Answer:
C. Some marsupial mole rats had a natural immunity to the virus.
Explanation:
According to Darwin's evolutionary theory, over time some of marsupial moles may have acquired natural immunity which evolves as an adaptive trait in the population. Since these organisms have more chance to survive and reproduce (survival of the fittest), they will likely transmit the natural immunity to the next generation .

How does a mutation get passed from parent to offspring?
Answer:
Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations.

Without photosynthesis, life would not have been able to proliferate the way it had over the past several million years. Identify which single called organism made this possible
Answer:
This is the Photosynthetic Cyanobacteria. it was the ability of this unicellular organisms million of years ago, through photosynthesis; that lead to the emergence of separate singular organisms the plants. Plants constantly undergo photosynthesis as it absorbs CO2, and make use of sunlight to to produce carbohydrates for animals to survive. And this leads to the emergence of animals which feeds on the plants, and therefore re population of the Earth occurs.

What is the purpose of the cell cycle?
Answer:
The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. These processes define the two major phases of the cell cycle.

Explanation:
You learned about the aptly named enzyme Citrate Synthase. There are more enzymes that count citrate as substrate or product. Compare and contrast two reactions below that each split two carbons from citrate to make oxaloacetate. One catalyzed by the enzyme ATP Citrate Lyase and the second catalyzed by Citrate Lyase.
Acetyl-CoA
Citrate → ↑ → Oxaloacetate lyase
CoA-SH → ↑ ↑ ←ATP ↓→ ADP + Pi
ATP Citrate
Acetate
Citrate → ↑ ↓→ Oxaloacetate
Citrate lyase
Which of the following is an accurate statement about why ATP is required by ATP Citrate Lyase?
a) The hydrolysis of the thioester involving CoA-SH helps split ATP into ADP and Pi.
b) The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.
c) The Acetyl-CoA is pulled rapidly away to make lipids so the reaction needs extra energy to make it fast enough to keep up with demand.
d) The two carbons of acetate are more energetic than those on Acetyl-CoA and therefore don't need ATP to split them from citrate.
e) ATP is required to spit the two carbons from citrate.
Answer:
b) The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.
Explanation:
In the citrate cycle, we know that lysis is mediated by the hydrolysis of ATP, which is the fuel of the reaction, so the correct answer is B. The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.

Explanation:
In a garden plot, you count 50 tall plants and 50 short plants. All the plants are offspring of the same two parent plants. What is the ratio of tall to short plants?
Answer:
50 to 50
Explanation:
Let me know if it’s right
The ratio of tall to short plants is 1:1 or 50 tall plants to 50 short plants. The ratio is expressed as 1:1 because the number of tall plants and short plants are equal.
What is phenotype?Phenotype refers to the observable physical and behavioral characteristics of an organism, which are determined by the interaction between its genetic makeup (genotype) and the environment. The phenotype can include traits such as height, eye color, body shape, and even personality traits.
These characteristics are influenced by both genetic and environmental factors, such as exposure to sunlight, diet, and other environmental conditions. In many cases, a single gene may have multiple effects on the phenotype, and many genes may work together to produce a single trait. Phenotypic traits can also be influenced by epigenetic changes, which involve alterations in gene expression without changes to the underlying DNA sequence. Understanding the relationship between phenotype and genotype is crucial for fields such as medicine, agriculture, and genetics.

on what characteristic of an organism does natural selection exert pressure?
a. allele frequency
b. gene pool
c. genotype
d. phenotype
Answer: option D.
Phenotype
Explanation:
Theory of natural selection shows that different organism survive, adapt and reproduce in their environment due to their different phenotypic variation. The phenotypic variation exist among individual organisms and it is heritable which is transfer from one generation to another.
Phenotype are traits or physical characteristics or observable characteristics of organism e.g organisms appearance, behavior e.t.c.
Answer:
d. phenotype
Explanation:
Natural selection exert pressure on the physical characteristics of organisms, that is, the phenotype.
Natural selection refers to the variation in the survival and reproduction of individuals within a population based on how adaptable they are to the environment in which they live.
The forces of natural selection act on the physical characteristics of individuals, that is how physically fit or unfit individuals are. Individuals that posses physical characters that makes them to be better adapted to the environment survives and reproduce better than their counterparts that are less adapted. Natural selection thus selects for the physical characters that make the individuals to be better adapted.
The correct option is d.
What part of the fungus is seen in the woods or on the lawn? Please help I will mark you the branniest!
Damp conditions can bring out other types of fungi that can create more serious problems for your lawn. Brown patch, fusarium blight, and rust are a few of the diseases that thrive in wet grass.
Polypores are also called bracket fungi, and their woody fruiting bodies are called conks. Most polypores inhabit tree trunks or branches consuming the wood, but some soil-inhabiting species form mycorrhiza with trees. Polypores and their relatives corticioid fungi are the most important agents of wood decay.

When considering human impacts to ecosystems, identify the incorrect statement:
Select one:
a. cod, swordfish, halibut and mackerel populations are especially vulnerable to collapse
b. coral reefs providing critical habitat and sources of food for tropical fish are slowly recovering, due to successful enforcement of fishing quotas
c. aquaculture may provide a sustainable alternative for raising farmed fish to feed a growing human population, allowing ocean fisheries to recover
d. over half of global ocean fisheries populations have become severely overharvested within the past century
Answer:
coral reefs providing critical habitat and sources of food for tropical fish are slowly recovering, due to successful enforcement of fishing quotas
Explanation:
This is a wrong statement because coral reefs contrary to the statement is not recovering, Over-fishing an destructive fishing,(to meet up with increasing demand) are some of the human impacts reltively control by the enforcement.
But,acidification (eutrophication), and mass coral bleaching from global warming are not restricted by the enforcement of fishing quotas and are drastically reducing the population of the reefs.This in turn affecting the survival of the fishes, reducing the population,

Nadeau et al., (Royal Soc. B. 2007) Reconstructed dN/dS ratios for genes involved in sexually dimorphic plumage in pigeons and their relatives.
i. Let’s imagine that Nadeau et al., tested 5 genes, and got the followingdN/dS ratios:
gene1: 0.01
gene2: 0.05
gene 3: 0.90
gene 4: 1.01
gene 5: 2.34
Which gene has a dN/dS ratio that provides the strongest evidence of negative (‘purifying’) selection?
Answer:
The correct option is gene 1 with the dN/dS ratio of 0.01
Explanation:
In order for negative selection to occur, the dN/dS ratio has to be between 0 and 1. There three genes that lie within this range, and hence, we can choose the smallest one to provide the strongest evidence among those to represented as the one being negatively selected. Where the dN/dS ratio is equal to 1, it means neutral and where the dN/dS ratio is greater than 1, it means positive selection.
