Question 1. What change led to an increase in the number of light-colored moths within the population?
1. More mutations
2. Decreased pollution
3. More dark colored trees
4. Fewer humans
Question 2. Claim: Individuals in a population have genetic variations that can be passed on to their offspring. Refer back to the rabbits in the desert from the natural selection activity we did in class. How could an organism's traits influence the survival rate of the population?
Answers
Answer: 1. 1. More mutations. 2. According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Explanation:
Hitchhiker’s thumb (H) is dominant to no hitchhiker’s thumb (h). A woman
who does not have hitchhiker’s thumb marries a man who is heterozygous for
hitchhiker’s thumb. What is the probable genotypic ratio of their
children?
Group of answer choices
50% Hh : 50% hh
100% HH : 0% hh
75% Hh : 25% hh
0% Hh : 100% hh
Answers
Answer:
there is a 50 50 chance
Explanation:
have a nice day!;)
The probable genotypic ratio of their children is 50% Hh : 50% hh because the man is heterozygous for the hitchhiker’s thumb, hence option A is correct.
What is a heterozygous condition?In some crosses, there are two conditions, in which some alleles are heterozygous and some are homozygous. In the homozygous trait, both alleles are the same, it may be dominant or recessive HH and hh, respectively.
The cross is between a woman who does not have a hitchhiker’s thumb and a man who is heterozygous for a hitchhiker’s thumb.
Cross: Hh X hh
Gametes: H and h
Genotype: Hh, Hh, hh, hh
Phenotype: 50% of hitchhiker’s thumb and 50% not having hitchhiker’s thumb.
The cross is attached in the image below.
Therefore, due to the heterozygous condition of man genotypic ratio of their children is 50% Hh: 50% hh.

Name and give examples of 2 major types of mutations. What do they have in common? How are they different?
Answers
Answer:
The correct answer would be - Two major types of mutations are deletions and substitutions.
Explanation:
The two major types of mutations are deletion and substitution, other than these there are many more mutations that are categorized under gene mutations and chromosomal mutation.
The deletion mutation takes place in the conditions where the DNA deletes or missed copying the nucleotide in a new DNA molecule. This type of mutation can occur in one or more nucleotides. Whereas Substitution mutation occurs when there is a wrong nucleotide added to the DNA sequence or substitute with other.
Both could be deleterious and takes place at the nucleotide level. Both mutation depends on the number of nucleotide or the location of the mutation on the gene.

Geranium leaves grow in positions that permit the optimum use of light as a result of
Answers
Answer:
do you work stop cheat broo this evan btw
Explanation:
Geranium leaves are typically arranged in a way that allows for optimal use of light through a process called "heliotropism" or "solar tracking."
What is heliotropism?Heliotropism is the ability of plants to orient themselves towards the direction of the sun to optimize their exposure to light.
Geranium leaves are arranged in a rosette pattern, with each leaf emerging from the base of the stem and spreading outwards. The leaves are arranged in a way that maximizes their surface area while minimizing shading of other leaves. This arrangement allows the leaves to capture the maximum amount of sunlight possible.
Additionally, geranium leaves have a waxy cuticle that helps to prevent excessive water loss and damage from UV radiation. The leaves also have chloroplasts, which contain chlorophyll and are responsible for photosynthesis, the process by which plants use sunlight to produce energy.

Houses have been built around a small retention pond, increasing the fertilizer runoff into the pond. This has led to algal blooms in the pond which periodically reduce the amount of dissolved oxygen available in the water. What will be the most likely long-term effect on the fish population living in the pond if the situation with the fertilizer does not change?
The fish population will grow as more offspring are born that can take advantage of the new conditions.
The population will be replaced by a different species of fish that consumes algae for food.
The fish population will learn to survive with less oxygen and more algae in the water.
