Answer:
This question describes a PROTEIN
Explanation:
Proteins are one of the four biological molecules in living systems. It is a biological polymer composed of monomeric units called amino acids, which are chemically joined together by peptide bonds.
An amino acid structurally consists of a central carbon atom bonded to an hydrogen atom, carboxylic acid group (-COOH), an amine group (-NH2) and a R side chain, which distinguishes one amino acid from another. Since all amino acids have a nitrogen-containing amine group, all proteins also contains nitrogen in their structure. Hence, a protein consist of an hydrocarbon (CHO) with a nitrogen atom.
Identify the eukaryotic cellular locations of the fundamental processes that are involved in the central dogma of molecular biology by dragging the correct labels to their targets.
Answer:
See the answer below
Explanation:
The central dogma gives a description of how genetic information travels in biological cells from DNAs to proteins. DNAs are first transcribed into messenger RNAs in a process known as transcription and the resulting mRNAs are used in the synthesis of proteins in a process known as translation.
In eukaryotic cells, transcription process happens within the confines of the nucleus because the genetic material in the form of DNAs are always located in the nucleus. Thereafter, the mRNAs generated from transcription are transported to the cytoplasm of the cell where they become translated into proteins.
Hence;
Transcription happens in the nucleus of the cell.Translation happens in the cytoplasm of the cell.Select the term that describes the constant mutation of the influenza virus glycoproteins over time:_________.

In a muscle twitch, which best describes what is happening during the latent period?
Answer:
During latent period, the muscle is preparing itself for contraction which comprises of biochemical activities from the stage acetylcholine bind to sarcolemma through cross-bridge formation.
Explanation:
A single muscle twitch has three stages which are latent period, contraction phase and relaxation stage
During latent period, the muscle is preparing itself for contraction which comprises of biochemical activities from the stage acetylcholine bind to sarcolemma through cross-bridge formation because the latent period is a short delay from the time the action potential get to the muscles until tension can be seen clearly in the muscle and the action potential is being propagated along the sarcolemma.

The scuba diver is a living system. The scuba gear, or self-contained underwater breathing apparatus, is a system of air exchange. How are these two systems interacting? What are the inputs and outputs of these systems?
Answer:
Input: oxygen (or air generally), breathed in by the scuba diver
Output: carbon dioxide exhaled by the scuba diver
Explanation:
The scuba gear is absolutely essential to sustaining this activity by sea divers. It serves the purpose of recycling the air breathed out by the person by filtering out the carbon dioxide. It also makes up for the oxygen that gets used so that the diver can continue breathing in a circuit. Thus, oxygen is considered as input and CO2 as output in this case.

Explanation:
Plate tectonics is the theory that the Earth’s crust is made up of plates that glide over a layer of mantle. A prediction of this theory is that the plates will move relative to each other as they move over the mantle. To test this hypothesis, a scientist places a marker on two adjacent plates to measure their movement over a decade. What would be the expected result of the experiment? How would you interpret the results if the scientist sees no movement?
Answer: So the result of this experiment would be that the makers are either further away from each other or closer to each other, confirming that the tectonic plates which are moving and are not static. North America plate, and on the South American plate, they move at pretty much the same speed, and also in the same direction, so with setting up makers we can not get to valid result. This is why they don't see no moment.
Answer: The result for this given experiment is that makers are further away from each other or closer to each other. North america plate and the south plate can move at the same speed, the same direction, by the same time. This is why they don't see no movement.
What is the probability that the first offspring from the cross listed below will be heterozygous for all loci?
aa Bb dd Ee x AA bb Dd Ee
Answer and Explanation:
Cross: aa Bb dd Ee x AA bb Dd Ee
We can calculate the probability of getting heterozygous individuals in the progeny by using the product rule. Assuming that these four genes assort independently (events that occur independently from each other), we can infer that the F1 will have the next genotypic proportions for each gene:
1) aa x AA
F1) 4/4=1 Aa
2) Bb x bb
F1) ½ bb
½ Bb
3) dd x Dd
F1) ½ dd
½ Dd
4) Ee x Ee
F1) ¼ EE
2/4 = ½ Ee
¼ ee
So, to know what the probability is that the F1 of being heterozygous for all loci, we must multiply the respective individual probabilities of getting a heterozygous genotype, like this:
1 Aa x ½ Bb x ½ Dd x ½ Ee = 1/8 AaBbDdEe
Researchers have suggested that people can be divided into chronotypes. A chronotype identifies an individual as a(n)
Answer: morning type or an evening type
Explanation: According to research, a chronotype identifies an individual as a morning type or an evening type. By definition, a chronotype is the natural disposition of an individual to be more alert or lethargic at different times of the day (especially in the morning or in the evening), depending on a variety of factors associated with circadian rhythms (the 'internal body' clock that regulates the 24-hour cycle of biological processes in both animals and plants).

A. They initiate DNA repair processes to resolve DNA damage.
B. They promote uncontrolled cell division.
C. They induce apoptosis in response to DNA damage.
D. They act at cell cycle checkpoints to regulate progression through the cycle.
E. They enhance cell growth by causing certain signaling pathways to remain constitutive active.
Answer:
A, C and D
Explanation:
Tumor suppressor genes encode proteins that act to inhibit cell proliferation and thus repress the development of tumors, while oncogenes are genes whose overexpression induce carcinogenesis. Tumor suppressor proteins inhibit tumor growth by repairing errors during DNA replication, by suppressing cell cycle progression and by inducing apoptosis (cell death). A well-know tumor suppressor is the protein p53, which is a transcription factor that triggers antiproliferative cell programs by inducing or inhibiting critical effector genes.

The independent variable in the experiment is A. the jar covers.
Explanation:
The independent variable in an experiment represents the thing that the person conducting the experiment changes or alters. One group in the experiment had covers (this represents the experimental group) and the other group had no cover (this represents the control group which was not exposed to the independent variable). Since the only thing that Redi changed between the two groups was whether or not the jars were covered, this represents the independent variable.
The number of jars and the contents of the jars were constant in both experiments, and the number of maggots on the meat is the dependent variable (the result of changing the independent variable).

Joe has been diagnosed with major depressive disorder. He interprets negative stressful events using a pessimistic explanatory style. This explanatory style creates a hopeless, depressed state, which then hampers the way he thinks and acts, causing more negative stressful events. Joe's depression is thus, at least in part, due to:
state-dependent memory.
rumination.
a biochemical imbalance.
indicators of depression.
Answer:
The correct answer is : state - dependent memory.
Explanation:
State dependent memories are recollections of memories that are set off or enhanced or increased by an individual's present mind-set in view of the relationship to memories framed when you were in a comparative state.
For example, pleasant memories are all the more effectively or strongly recalled when one is feeling happy and the equivalent goes for negative thoughts and sadness or outrage towards something. In this case Joe having more negative thoughts in response of depression or negative thoughts.
Thus, the correct answer is : state - dependent memory.
Joe's depression caused by pessimistic explanatory style of negative events is due to State dependent memory,
State dependent memory:
It is phenomenon in which people recall more information if their mental or physical state is same as the time event.

If a splice site were mutated so that splicing could not take place, what would the effect be on the mRNA?
Answer:
The mRNA will contain intron sequences and eventually be translated into a non-functional protein.
Explanation:
Splicing is the last stage involved in mRNA processing (the first two being 5' capping and polyadenylation). A mRNA transcript (result of transcription) contains both protein-coding regions (exons) and non-coding regions (introns). Splicing involves the removal of the introns from the mRNA sequence (by spliceosomes) and the rejoining of the exons.
If the site where splicing process should occur were mutated and splicing does not take place, this means that the introns will not be removed from the mRNA sequence, hence, the final transcript will contain both protein coding and non-coding regions.
If translation (synthesis of protein) eventually occurs, the mRNA that didn't undergo splicing will be translated into a protein molecule that is not functional. This is because the non-coding sequences will interfere with the reading frame of the coding sequences.

Select all of the following that are characteristics of heat.
In humans there is a dominant allele (A) for the absence of moles; while the recessive allele (a) results in the presence of moles. A couple who are both heterozygous for this locus (Aa) plan to have seven children.
a. Expand the binomial (p + q)7.
b. What is the probability that:
(i) The first child that is born will not have moles.
(ii) All of the children will have moles.
(iii) The first two children will have no moles and the last five will have moles.
(iv) Of the 7 children, 4 will have no moles and 3 will have moles
c. Assume this couple now have two children, one with moles and one without moles. What is the probability that the child born without moles is a carrier of the a-allele (ie heterozygous)?
Answer:
a. [tex](p + q)^7[/tex] = [tex]p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7[/tex]
b. i. 0.75
ii. 0.000061
iii. 0.012
iv. 0.17
c. 0.67
Explanation:
a. The expansion of the binomial (p + q)7 would be such that:
[tex](p + q)^7[/tex] = [tex]p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7[/tex]
b. Both couples are heterozygous:
Aa x Aa
AA Aa Aa aa
Since A is dominant over a,
probability of having mole (aa) = 1/4
probability of not having moles = 3/4
Therefore, the probability of the first child not having moles = 3/4 or 0.75
ii. Let the probability of not having mole = p and the probability of having mole = q. From the binomial expansion:
[tex](p + q)^7[/tex] = [tex]p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7[/tex]
Probability that all of the children will have moles = [tex]p^0q^7[/tex]
since p = 3/4 and q = 1/4
[tex]p^0q^7[/tex] = [tex](3/4)^0(1/4)^7[/tex] = 0.000061
iii. Probability that the first two children will have no moles and the last five will have moles = [tex]21p^2q5[/tex]
= [tex]21(3/4)^2(1/4)^5[/tex]
= 0.012
iv. Probability that 4 will have no moles and 3 will have moles out of the 7 children = [tex]35p^4q^3[/tex]
= [tex]35(3/4)^4(1/4)^3[/tex]
= 0.17
c. Probability that the child born without moles is a carrier of the a-allele = probability of heterozygous.
From the cross in (b), the genotypes of those born without moles are AA and 2Aa. Therefore, the probability of not having moles and be Aa is:
= 2/3 or 0.67
