Answer:
B. Human activities and natural events can damage the environment.,
Explanation:
Human activities are those activities carried out by a human being. The environment is being degraded daily as a result of the activities of man as well as natural occurrences e.g earthquake, tsunami, wild fire etc.

what is the endocrine system and how does it work
Answers
What Does the Endocrine System Do?
Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body.
The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction.
The endocrine system regulates how much of each hormone is released. This can depend on levels of hormones already in the blood, or on levels of other substances in the blood, like calcium. Many things affect hormone levels, such as stress, infection, and changes in the balance of fluid and minerals in blood.

3. You are studying a population of pangolins (a scaly anteater), and you determine that there are two scale phenotypes: a thick scale that is dominant to a thin scale. You also find that thick-scaled individuals are better able to survive encounters with predators.
What evidence would you need in order to determine if this selective advantage is changing the population? (1 point)
-The number of individuals displaying each phenotype in the current generation.
-The number of individuals displaying each phenotype in the offspring.
-The number of individuals that survive predator encounters.
-The number of individuals displaying each phenotype in both the current generation and the offspring.
Answers
Answer:
The number of individuals displaying each phenotype in both the current generation and the offspring.
Explanation:
The number of individuals displaying each phenotype in both the current generation and the offspring. The correct option is 4.
What is phenotype?The phenotype is the set of observable characteristics or traits of an organism in genetics.
The term encompasses the organism's morphology, developmental processes, biochemical and physiological properties, behaviour, and behavioural products.
To see if the thick scale phenotype's selective advantage is changing the population, we must compare the frequency of the thick scale phenotype in the current generation to its frequency in the next generation.
This would necessitate data on the number of people who exhibit each phenotype in both the current generation and their offspring.
As a result, the evidence we require to determine whether the selective advantage is changing the population is "the number of individuals displaying each phenotype in both the current generation and offspring."
Thus, the correct option is 4.

Cottontail rabbits closely resemble the fall and winter plants in which they hide

Answer:
In earlier generations, the rabbits that looked most like their surroundings survived and reproduced.
Explanation:
The cotton-tailed rabbits consist of 20 species that are found in America and have stubby tales with white under them. They're distributed over north, central, and southern America. They live in nests called forms, have an average life span of 2 years. Due to their camaflugeous nature, they change their coat color twice every year to protect themselves from predators.okay this is the question please answer if you know it because I'm not sure if it's a. or d. and thxxx :)

difference between parallel venation and reticulate venation
Answers
this is where you can get
The difference between parallel venation and reticulate venation is in parallel venation, the vein of the leaf blade is in a parallel pattern, and in reticulate the vein of the leaf blade is a net or web-like structure.
What is venation?Venation is the pattern of veins present in the leaves. There are different patterns of veins present in the leaves, parallel venation, for example, banana leaf, and reticulate venation, for example, papaya leaf.
Thus, In contrast to reticulate venation, where the vein of the leaf blade is arranged in a net-like pattern, parallel venation has the vein of the leaf blade arranged in a parallel pattern.

What is the importance of neutral variation in evolution?
A trait that is neutral in one environment may be advantageous in another.
It is usually removed from the population by natural selection due to its deleterious phenotypes in the environment.
A trait that is neutral will most likely be removed from the gene pool.
It will cause for a population to risk decline and extinction.
Answers
Answer:
A trait that is neutral in one environment may be advantageous in another.
Explanation:
Neutral variation refers to the variation (either genetic or phenotypic variation) which is unaffected by natural selection. Neutral variation is known to increase genetic variation, which is a prerequisite to evolutionary change. An allele may be neutral in one environment and beneficial (or deleterious) in another. In consequence, neutral variation in one environment may increase the response to selection in different environmental conditions.

Yellow-eyed salamanders have been cited as an example of Batesian mimicry; their orange body color and yellow eyes mimic the coloration of the toxic California newt. Although the salamanders are palatable, their mimicry of a unpalatable species tends to prevent predators from attacking. In a follow-up study, Kuchta et al. observed the reaction of Western scrub jays (predators with toxic newt experience) when presented with both a yellow-eyed salamander and a closely related species after being presented with a toxic newt. What was significant about this study
Answers
Answer:
It was a follow-up controlled experiment that showed how a species can influence selection in another species.
Explanation:
A follow-up (cohort) study is a type of study followed over time in order to determine the development of a particular outcome. Moreover, a controlled experiment is one in which conditions are controlled by the researcher, and thereby it is easier to determine the incidence of the outcome. In the case above described, researchers performed a follow-up controlled experiment in which they measured how a species can influence selective processes undergone by other species.
