A. graph 2 below
B. graph 3 below
C. graph 4 below
D. graph 5 below
Answer:
B. graph 3 below
D. graph 5 below
Explanation:
The original population of beetles (Graph 1) shows that most individuals had an intermediate phenotype between dark and light color. The graph expresses its highest point in the middle of the phenotypic ax, while the curve´s tails coincide with light and dark colors.
Probably, most of the trees inhabiting the whole island had some darkish color tone, which beetles used to camouflage and avoid predation.
When the company cleared the area and reforested, they planted light trees on one half and dark trees on the other half of the island. This change in the environment modeled the beetled phenotype, together with predation pressure.
If we consider the whole original population, we should say that it went under a disruptive selection. But if we think about the sides of the island separately, we could say that the population living on each side went under directional selection. We are not thinking about the whole population of beetled inhabiting the whole island, but two groups inhabiting each side of the island.
Graph 3 represents the beetles inhabiting the part of the land with dark trees. The population went under directional selection, and most of them turned into dark-colored to camouflage with the substrate in which they live.Graph 5 represents the beetles inhabiting the other part of the land with light trees. The population went under directional selection, and most of them became light-colored to camouflage with the substrate in which they live.In primary mutant screens, A) mutant flies are identified by morphology and then the mutant genes are isolated and studied. B) mutant flies are created by RNAi using random RNA sequences and then the genes affected identified. C) mutant flies are created by gain-of-function expression of random genes. D) two mutant flies are mated to determine if there is an effect on morphology.
Answer:
A) mutant flies are identified by morphology and then the mutant genes are isolated and studied.
Explanation:
The visualization of mutant flies is done with an experiment, where drosophila flies, also known as fruit flies, are captured and placed in closed bottles. The bottles have a mixture of banana and agar so that the flies can feed for a period of 15 days. During these 15 days, the flies made several crosses and over time, it will be possible to identify the appearance of mutant flies as a result of the number of crosses made inside the bottle. The mutant flies will be identified when the researcher is able to observe flies with legs, eyes and wings in different numbers than what is presented in a normal fly.
After being identified by their different morphology, the mutant flies will have their mutant genes isolated and studied.

Consider what you have learned about the role of genes, and in some cases their interaction with environmental factors, in human disease and traits, including complex traits associated with behavior and identify. How might this information be useful to your personal, social, academic and/or professional life?
Answer:
to adopt a healthy lifestyle in order to prevent and/or reduce the risk of developing complex diseases
Explanation:
Complex genetic diseases are diseases that have a genetic basis but often don't show a clear pattern of inheritance, i.e., the genes that encode for the trait of interest are localized in quantitative trait loci (QTL). In general, complex genetic diseases are multifactorial because both genetic and environmental factors play important roles in the development of this type of disease. Some well-known examples of multifactorial genetic diseases include, among others, heart diseases, diabetes, asthma, some type of cancers, etc. It is well known that healthy lifestyle habits such as maintaining a healthy weight, eating healthy foods, avoiding harmful substances, etc., can prevent complex genetic conditions from manifesting.

Does every gene combination show up in the offspring?
Answer:
Answer!
Explanation:
Okay so, genes come in different varieties; which are called allele. somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. BUT, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.
During meiosis I, chromosomal pairs randomly align along the metaphase plate. Each chromosome pair member carries one allele for each gene. Every gene combination shows up in the offspring.
Chance determines which of the 23 homologous pairs of both parents' chromosomes are inherited. The possible combinations of 23 chromosomal pairs total 8,324,608. As a result, the chromosomal combinations of two gametes are almost never identical.
Actually, each parent has two distinct gene pools. Additionally, only half of each parent's DNA is passed on to their offspring. and that the randomness of the portion that is passed down. All of these factors work together to guarantee that every child has a distinct collection of genes.

The graphs here show the distribution of beak depths for the ground
finches on Daphne Major, an island in the Galapagos. The bird beaks were
measured over a multi-year study, including a time period before and after
a drought. The drought reduced the supply of seeds and left most of the
seeds as thick-walled nuts that survived the drought. Analyze the data and
select the claim about natural selection and genetic diversity that is
supported by the data.
Natural selection tends to reduce genetic variation, as there was a smaller distribution
of beak depths, but it tends to select for the most fit phenotypes, as there was an
increase in average beak depth after the drought.
Natural selection tends to increase genetic variation, as there were more ground
finches after the drought, and it tends to select for the most fit phenotypes, as there
was an increase in average beak depth after the drought.
Natural selection tends to reduce genetic variation, as there was a smaller distribution

What are Decomposers?Decomposers are organisms that convert decaying organic matter into more basic components. They are an important component of the nutrition cycle because they convert complex chemical substances, such as nitrogen and carbon, into direct nutrients that can be absorbed by plants and other living things.
Some species of bacteria, fungi and insects are specialized decomposers. These organisms are essential to maintaining healthy soil because they aid in the recycling of nutrients and the breakdown of organic matter, which would otherwise build up and cause nutrient imbalances. Decomposers, which break down dead organisms and aid in the containment of pathogens, may be important in disease prevention.

Answer:
The correct answer is - not getting all NAD+ so burning more ATP to make up for the energy loss.
Explanation:
If the drug was administered and it would cause impedetion of the binding of NAD+ to electrons which causes decrease availability of the NAD+ that leads to less energy formation due to the use up more ATPs in the process of cellular respiration.
If NADH couldn't be formed as NAD+ will not binding, the cells will lose out on ATP produced. It will lead to weight loss due to burning out more ATP to make up for the energy loss.
