Answer:
1. Glucose breaks down into two pyruvates. CATABOLIC
2. Ammonia is added to glutamate to form glutamine. Anabolic
3. Four amino acids join to form tetrapeptides. Anabolic
4. A uracil base is added to an mRNA strand by RNA polymerase. Anabolic
5. Starches are digested into individual glucose molecules. CATABOLIC
6. Ribose and inorganic phosphate join together to form a nucleotide base. Anabolic
Explanation:
Chemical reactions are classified as anabolic and catabolic depending on whether they form or disintegrate structures, yielding energy to the medium or taking energy from the medium.
Anabolic reactions are those that take energy from the environment and therefore synthesize very complex molecules, of various bonds such as glycogen, starch, among other polysaccharides.
On the other hand, catabolism leads to the destruction of the unions of a chemical product, that is why they have greater entropy and is thus the greatest disorder.
Catabolism releases energy to the environment, it releases it.
For an anabolic reaction to happen, there must be a catabolic one, since it takes the energy released by catabolism, and for a catabolism to happen, an anabolism must first have arisen, that is, the formation of a molecule or particle that is dissociates.
The _____ variable, or factor, is what is being deliberately changed in the experimental group.
Answer:
Independent
Explanation:
The independent variable/factor is the one that is being changed on purpose during the experiment.
This variable is changed on purpose to see how it affects the dependent variable.
How do genes have an additive effect in polygenic inheritance?
Answer:
The traits that are determined by polygenic inheritance are not an effect of dominance and recessivity, and do not exhibit complete dominance as in Mendelian Genetics, where one allele dominates another. Instead, polygenic traits exhibit incomplete dominance so the phenotype displayed in offspring is a mixture of the phenotypes displayed in the parents. Each of the genes that contributes to a polygenic trait has an equal influence and each of the alleles has an additive effect on the phenotype outcome. Hope this helps!

A breakwater is a barrier built out into a body of water to protect a coast or harbor from the force of waves.
If every cell in the body gets the same DNA, how do the cells of an embryo make different structures and take on different roles
Answer: The options are not given, here are the options.
A. Different transcription factors are active in different cells
B. Different transcription factors are encoded in the DNA.
C. Genes are spliced differently in different cells.
D. Translation is regulated so that different cells may make more of certain proteins.
E. Some cells lack ribosomes while others use them.
F. cells delete a set of unused genes from their chromosomes.
The correct options are;
A. Different transcription factors are active in different cells
C. Genes are spliced differently in different cells.
D. Translation is regulated so that different cells may make more of certain proteins.
Explanation:
Every cell in the body have the same DNA but different function because a single cell in the body divides many times into several cells and these cells have the same DNA , DNA is the genetic information needed to make a person and it is stored in over 20,000 human genes found in almost all the cells in the body.
For the gene to be expressed into information, it must be made into protein and the protein goes out and perform some specific functions.
And for a cell to work, alot of proteins must be made to perform different functions.
Different transcription factors are active in different cells which make cells to perform different roles and functions.
Genes are spliced differently in different cells to make different proteins performing different task.

Primate communication can be compared to human communication in that:________.
a. primate communication is very simple and across all the species consists of only a handful of "meaningful" sounds; this is entirely different from human language.
b. although some primates have the ability to transmit meaning from one individual to another, this always happens within a species, never between species; this is similar to humans, since humans do not really understand other animals either.
c. many primates make sounds that seem to be labels for things, like specific food items or specific predators, but primate communication lacks nuance or complexity of any kind; this is unlike human language.
d. for at least some Old World monkeys and apes, communication seems to be very context dependent, and specific sounds can have different meanings by making small changes; this is like human language.
Answer:
b. although some primates have the ability to transmit meaning from one individual to another, this always happens within a species, never between species; this is similar to humans, since humans do not really understand other animals either.
Explanation:
Transmission of information or message often takes place between species of same kind.
Human can better understand the language, sounds, signs made by fellow human and not sounds from other species of animals or other organism, this is because language or system of communication is attached to a particular domain or organism of a species. Birds communicate differently from a Goat, human does likewise from other primates.
The system of communication is used to a particular locality and if not learned it is not understandable by another species of organism.
Primate communication can be compared to human communication in that for at least some Old World monkeys and apes, communication seems to be very context-dependent, and specific sounds can have different meanings by making small changes; this is like human language.
Primates use a variety of communication channels, including vocalizations, gestures, and facial expressions. These channels can be used to convey a wide range of information, including the location of food, the presence of danger, and the emotional state of the individual.
In some primates, communication seems to be very context-dependent. This means that the meaning of a particular vocalization or gesture can vary depending on the context in which it is used.
For example, a chimpanzee's "pant-hoot" vocalization can be used to greet another chimpanzee, warn of danger, or to initiate a sexual encounter.
Human language is also context-dependent. This is why we can use the same word to mean different things in different contexts. For example, the word "bank" can refer to a financial institution, a riverbank, or a slope.
The ability to use context to convey meaning is a key feature of human language. It is also a feature of the communication of some primates, which suggests that this ability may have evolved early in the history of the primates.

Constants ("controlled variables")
and a control are easily confused by
students! How would you explain the
difference between the two words?
Answer:
Please find the explanation below
Explanation:
The control variable of an experiment or constant are variables that the experimenter keeps constant or unchanged for all the groups throughout the experiment. The constant can influence the result of the experiment if not kept unchanged.
On the other hand, a control group is a group that does not receive any experimental treatment in order to compare the effect of the independent variable on the dependent variable. The control group receives every other thing including the constants, with the exception of the independent variable.
In a nutshell, the control group is used as a standard comparison for the experiment performed i.e. compare what will happen if an independent variable is changed in the experimental group while the control variable is simply a factor that must be kept constant throughout the experiment to avoid alterations.

It is actually the ____________ of molecules between chloroplasts and mitochondria that allows a ____________ of energy from the sun through all living things.
Answer:
It is actually the cycling of molecules between chloroplasts and mitochondria that allows a flow of energy from the sun through all living things.
Hope it helps.
Please mark it as Brainliest.
It is actually the transfer of molecules between chloroplasts and mitochondria that allows a flow of energy from the sun through all living things.
Chloroplasts and mitochondria are two organelles found in cells. Chloroplasts are found in plant cells, while mitochondria are found in all eukaryotic cells. Chloroplasts are responsible for photosynthesis, the process by which plants convert light energy into chemical energy. Mitochondria are responsible for cellular respiration, the process by which cells use chemical energy to produce ATP, the cell's energy currency.
The transfer of molecules between chloroplasts and mitochondria allows a flow of energy from the sun through all living things. In photosynthesis, chloroplasts use light energy to convert carbon dioxide and water into glucose and oxygen. Glucose is then used by cells as a source of energy, and the oxygen is released into the atmosphere. In cellular respiration, mitochondria use glucose and oxygen to produce ATP. ATP is then used by cells to power their activities.

Which characteristics is used to identify an amino acid?
Answer:
Each amino acid contains a central C atom, an amino group (NH2), a carboxyl group (COOH), and a specific R group. The R group determines the characteristics (size, polarity, and pH) for each type of amino acid.
Explanation:
In order to identify an amino acid, there are several characteristics that can be used. One of the main characteristics is the presence of an amino group (-NH2) and a carboxyl group (-COOH) in the molecule.
What are the key characteristics of amino acids?This is a functional group containing a nitrogen atom, represented as -NH2. All amino acids have an amino group attached. This is another functional group present in amino acids, represented as -COOH.
Other key characteristics include the presence of a side chain (R group) that can be polar, nonpolar, or charged, and the ability to form peptide bonds with other amino acids.
Amino acids are the building blocks of proteins and are essential for many biological processes. There are 20 different amino acids that are commonly found in proteins, each with its own unique side chain and properties.
By understanding the characteristics of these amino acids, scientists can better understand the structure and function of proteins and how they contribute to the workings of the body.

Lucy lab tech is to administer a glucose tolerance test on Mrs. Sweet. Mrs. Sweet is a fairly large lady weighing 330 pounds. The normal 8 oz. bottle of glucola used in the test is designed for patients with a weight range of 100-220 pounds. Patients weighting less that 90 or more than 250 pounds should be given a dosage of 2 ml/kg. How many ounces (oz) of glucola should Lucy give to Mrs. Sweet?
Answer:
10.12 oz
Explanation:
Since Mrs. Sweet weighs outside the 100-220 pounds, she will receive a dosage of 2 ml/kg. Her weight is 330 pounds.
1 pound = 0.453592 kg
330 pounds = 330 x 0.453592 = 149.685 kg
2 mL of glucola is required for 1 kg of weight. Hence 149.685 kg would require;
2 x 149.685 = 299.37 mL
1 oz. of glucola is equivalent to 29.5735 mL. Hence 299.37 mL would be equivalent to,
299.37/29.5735 = 10.12 oz. of glucola
Lucy should therefore give Mrs. Sweet 10.12 ounces of glucola.
⦁ Do most of the finches have beak depths near the lower extreme, the middle, or the higher extreme of the range?
Answer:
Near to the middle.
Explanation:
Most finches have beak depths close to the middle, which benefits the feeding and justifies the reason why most of these birds have this beak extension.
As you know, tendons are birds of the family of fringilids, they are known for having a very pleasant song, which allows people to wish to have them at home, as a pet.
They feed on grass seeds and insects. This type of food is benefited by the medium sized beak, allowing the tendons that have this type of beak to have survival advantages.
Answer:
Most of the finches have beak depths near the middle extreme of the range since the graph shows us that most of the finches (270) have a beak depth of 10mm, so we can infer most of them have a medium sized beak, which provides them many survival advantages.

Telomeres serve as caps at the ends of linear chromosomes. Which of the following is not true regarding the replication of telomeric sequences?
A) The lagging-strand telomeres are not completely replicated by DNA polymerase.
B) Telomeres are made of repeating sequences.
C) Additional repeated sequences are added to the template strand.
D) The leading strand doubles back on itself to form a primer for the lagging strand.
Answer:
D) The leading strand doubles back on itself to form a primer for the lagging strand.
Explanation:
Telomeres are the end sequences of the linear cromosomes of DNA, and are formed by tandem repeats of simple DNA sequences. Because DNA polimerases can only extend the primers in the 5' to 3' direction, they can not copy the 5' ends of the linear molecules of DNA. A reverse transcriptase called telomerase is needed to replicate the telomeres.
This telomerase carries its own RNA template, which is complementary to the repeated sequences in the telomeres, as part of the enzymatic complex. The loose end of telomeric DNA binds to the ARN in telomerase, which will then function as a template for the extension of the template conductor strand in another unity of repetition. The lagging strand can be synthesized as a conventional initiation of RNA and polimerase activity.

"The application of evolutionary theory to the debate over modern human origins focuses on which process of evolution?"
Answer:
The process of gene flow
Explanation:
Gene flow refers to the transference of genetic variation from one population to another. High rates of gene flow are known to modify the allele frequencies and reduce genetic differences among groups. Gene flow limits the process of speciation by combining gene pools form different groups. In humans, for example, it has been shown that migration in the past decreased genetic variation among their populations, thereby leading to the homogenization of genotype frequencies among geographic groups. It is for that reason that in population genetics the concept of 'human races' is now often recognized as erroneous and inadequate.
