Answer:
There are no tables but it should be a bell curve. as a population of whales rise the population of seals will decrease, eventually creating a plateau in the whale population. shortly after the plateau in the whale population the whale population will begin to decline ( as food becomes less available) causing the seal population will begin to rise and restabilize. this pattern should continue cyclically creating a wave function on a graph!

QUICKLY! The chemical reaction equation of photosyntesis is shown here: What information is not given in this equation. It does not show if the reaction is reversible. It does not show the reactants needed for the reaction. It does not show that photosynthesis consists of many separate steps. It does not show the number of molecules required to produce glucose.
Answer:
C: It does not show that photosynthesis consists of many separate steps.
Explanation:
Photosynthesis is a unique process carried out by the cells of autotrophic organisms. It is the process whereby they synthesize their own food in form of sugars (glucose) in the presence of sunlight. Ideally, the photosynthetic process makes use of carbon dioxide (C02) and water (H20) in the presence of light energy (from sun) to produce glucose sugar (C6H12O6) and oxygen (02). The general photosynthetic equation is as follows:
6CO2 + 6H20 + light → C6H12O6 + 6O2
However, the process is not as simple as portrayed as it involves many separate steps that collectively forms the photosynthetic product (glucose). Photosynthesis occurs in two major stages namely: light stage and light independent stage, which in turn consists of series of reactions that forms the products.
Therefore, the equation attached to this question describes photosynthesis but It does not show that photosynthesis consists of many separate steps.
Answer:
C: It does not show that photosynthesis consists of many separate steps.
Explanation:
The force of a muscle contraction is higher when the muscle is stimulated every 0.5 secs than when stimulated with the same voltage every 0.05 seconds.
a. True
b. False
Answer:
b. False
Explanation:
Increasing the frequency of muscle stimulation causes wave summation to occur, which causes an overlap of muscle twitch. When this muscle summation happens, the force generated in the muscle increases. This means that stimulating the muscle every 0.5 seconds will generate less muscle contraction force than when stimulated every 0.05 seconds
The idea that chromosomes orient themeselves randomly during metaphase I is ________________________. This leads to ___________________ combinations of genes.
Answer:
The idea that chromosomes orient themselves randomly during metaphase I is Independent Assortment. This leads to more combinations of genes.
Explanation:
During metaphase I, the pair of chromosomes align in the plate of the cell. In this step, the independent assortment takes place.
The independent assortment is the distribution of different genes into two gametes, is independent, because the distribution of the different genes, does not influence the distribution of the other genes. The independent assortment leads to new combinations of genes from the parental and maternal side, resulting in offsprings that do not look exactly like their parents.

A purebred tall pea plant is cross-pollinated with a tall, heterozygous pea plant. Use a Punnett square to determine the probability the offspring inherita
recessive short allele. (I point)
75%
25%
0%
50%
Answer:
The correct answer is - 25%
Explanation:
A cross between true tall pea plant and heterozygous tall pea plant is the cross of tall allele whic is TT and heterozygous which is Tt, so the gametes will be formed would be - T and T by true tall plant and T, and t allele by heterozygous plant.
The Punnett square of this cross is attached with the answer, where 2 heterozygous offspring and two tall offspring produced. In which there is only two recessive short allele formed in this generation out of 8 alleles.
So the probability of short allele would be:
= (2/8) *100
= (1/4) *100
= 25%

The structure of DNA is double stranded, so each side serves as a template for a new strand. The correct option is C.
What is DNA replication?Replication is the procedure by which the DNA of the genetic code is copied in cells.
Before dividing, a cell must duplicate (or replicate) its a whole genome so that each eventually results daughter cell has its own entire genome.
The DNA replicates itself multiple times during the process of replication. It is a biological polymerization that goes through the steps of commencement, elongation, and termination.
The reaction is catalyzed by enzymes. The main enzyme in the process of replication is DNA Polymerase.
DNA replication occurs in eukaryotic cells' interphase nuclei. At the S-stage (synthesizing) of the cell cycle, DNA replication occurs prior to mitosis.
Thus, the correct option is C.

Hereditary fructose intolerance is a genetic condition caused by a variant in the ALDOB gene, which is critical for fructose metabolism. Infants with this condition do not initially display symptoms, but as they are transitioned from breast milk or formula to solid foods, in particular fruit-based foods, they begin to display symptoms, which include vomiting, diarrhea, and low blood sugar. Individuals who do not consume fructose do not display these symptoms. Which of the following describes this condition?
a. It is incompletely penetrant, due to environmental factors.
b. It has variable expressivity, due to environmental factors.incorrect
c. It is incompletely penetrant, due to genetic factors.
d. It has variable expressivity, due to genetic factors.
It has variable expressivity due to the environmental factors.
The variation in expressivity occurs due to the environmental factors of that individual. Expressivity describes the differences observed in the phenotype between two individuals that belongs to same genotype.
In the condition, when the patient is allowed to consume the fructose based food, so it expresses the change in its body due to no tolerance against fructose so we can conclude that the change occurs due to environment not due to genetics.

Which of the following is the term for tightly packed sheets of cells that cover organs and outer surfaces?
a. Epithelial tissue
b. Connective tissue
c. Muscle tissue
d. Nervous tissue
Answer:
Epithelial tissue
Explanation:
The correct option would be the epithelial tissue.
Epithelial tissues are made up of tightly arranged cells and primarily functions as protective covers for organs and outer surfaces. Usually, a side of the component cells in epithelial tissue are in contact with organs which they are covering through a non-cellular basement membrane and the other side of the cells are free.
The non-cellular basement membrane that connects the cells in epithelial tissues to organs and surfaces is secreted jointly by the epithelial and connective tissues and usually made up of protein and carbohydrate.

When does facilitated diffusion occur?
-When one liquid has a higher osmotic pressure than the other.
-When certain large molecules are unable to move through the membrane
without the help of channel proteins.
-When ATP is available to assist in moving molecules.
-When there's a strong membrane potential present, with the inside of the cell
being more negative than the outside of the cell.
Answer:
When certain large molecules are unable to move through the membrane without the help of channel proteins
Explanation:
Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.
Bats have oversized ears, which help the bad you sound waves to detect the motion of their prey which example of the characteristics of life is most similar
This question is incomplete because there are no options; here is the complete question:
Bats have oversized ears, which help the bad you sound waves to detect the motion of their prey which example of the characteristics of life is most similar
A) A yeast cell splits itself in half to create a new organism.
B) A rat hides in its hole when it sees an approaching predator.
C) A fungal cell releases carbon dioxide back to the atmosphere.
D) A human child grows taller every year.
The answer to this question is B) A rat hides in its hole when it sees an approaching predator.
Explanation:
One of the characteristics of living organisms is the ability to adapt or respond to the environment. This feature of life is the one shown by bats in this case because the oversized ears are a result of evolution and adaptation that help bats to have more chances of survival. Similarly, rats hiding to avoid predators is a result of adaptation that helps rats survive by avoiding predators. Thus, rats and bat show the same characteristic of life.

Describe Dr. Vellend's unifying theory of ecological communities (the factors that determine community structure). Where do concepts like competition, predation, habitat suitability, disease and parasitism, and disturbance (most of what we covered this semester) fit into his theory
Answer and Explanation:
Community ecology is a discipline that studies the organism's communities and the manner in which populations of species interact with each other within a particular habitat. Mark Vellend is an eco-evolutionist that developed a theoretical framework of ecological communities from a unified functional perspective. This theory is based on four forces of evolutionary biology: selection, drift, dispersal and speciation. This theory is used to explain how species interactions including parasitism, competition and predation may influence population fluctuations. On the other hand, this theoretical framework can also be used to understand how colonization, disturbance and habitat suitability components alter the dynamics of interacting species.
population of squirrels live together in forest an event occurred that caused the population to diverge into two different species over a long period of time which of the following is most likely the event occurred
A natural disaster.
Explanation:
A natural disaster would most likely have occurred to have the population of squirrels completely diverge from each other in order for them to become two separate species.
If a tornado, flood, earthquake, or another type of a natural disaster were to happen, it may have caused drastic damage to the ecosystem and environment of the squirrels. This would most likely cause the squirrels to split up, or diverge from each other and go to separate places in search of a new home.
Over time, these squirrels will reproduce with their own group. Each new group of squirrels, as they are both in different environments now, will have different adaptations from each other. This will eventually make it so they will never be able to reproduce with each other again if they were to meet, as they are now completely different species of squirrel.

Consider a material for a vascular graft application with proteins adsorbed to its surface and a second material with proteins covalently attached to its surface. For which material would you expect the protein layer to be more stable under flow conditions similar to those found in a blood vessel? Why?
Answer is given below :
Explanation:
Individual-specific proteins are placed on the graft material so that the body does not recognize the graft as a foreign substance and treats it as a part of the body’s natural tissue structure. If the body recognizes the graft as a foreign substance, it produces an immune response against it and leads to a graft rejection reaction by the body. In order for these proteins to attach to grafts, a covalent bond for absorption must be preferred. Absorption is a reversible process and, if used, can lead to de-absorption of bound proteins, including blood, after dissolving by turbulence and pulling to the grafting material by blood flow (velocity up to 40 cm/sec). The remaining infectious tissue is detected foreignly, activating the immune response. On the other hand, covalent bonding is irreversible in nature and vascular flow does not have a disruptive effect on the bond between the graft and the protein, reducing the stable state of the graft and the possibility of rejection.Put the vocabulary words in order from largest level of organization to smallest.
