The brachial plexus is associated with which of the following?
A. Innervation of the upper limbs
B.Innervation of the lower limbs
C.Axillary nerve is a terminal branch
D. A and B are correct
E. A and Care correct
Answer:
innervation of the upper limbs
The brachial plexus is a nerve network located at the base of the neck and the axillary fossa associated with sensory and motor innervation for the entire upper limb.
What is the brachial plexus?It is responsible for providing the motor (muscle), sensory and sympathetic innervation of the upper limb.
Through it, the spinal cord is connected with all the peripheral nerves of the upper limbs and all the sensorimotor information of these segments is also transmitted.
Therefore, we can conclude that the brachial plexus is a nerve network located at the base of the neck and the axillary fossa associated with sensory and motor innervation for the entire upper limb.

Which factors were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection?
(1 point)
1. a change in the diet of human populations as they settled in colder climates
2. the clothing worn by humans in the early 8th century
3.the interaction of human populations with predators in colder climates
4.the impact of UV radiation on folate and Vitamin D levels in human populations
Answer: The answer is 4
Explanation:
Vitamin D controls your skin pigment. It's kind of like when someone has an iron deficiency they get bruises and they turn a whiter shade.
Hope I helped :)
The factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection are the impact of UV radiation on folate and Vitamin D levels in human populations.
Ultraviolet B radiation produces diet D in human skin. Ultraviolet radiation can, however, smash folate. Folate is critical for the speedy increase of cells, particularly at some point in which its deficiency can motivate neural tube defects. The human frame additionally has a mechanism to save you overproduction of vitamins.
What is UV radiation?Ultraviolet is a shape of electromagnetic radiation with a wavelength from 10 nm to four hundred nm, shorter than that of seen light, but longer than X-rays. UV radiation is found in sunlight and constitutes approximately 10% of the whole electromagnetic radiation output from the Sun.
Thus it is learned that the above answers are well-explained factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection bout.

What is the answer to this question?
Answer:
DDDDDDDDDDDDDDDDDDDDDDDDDD
Answer:
The answer is C.
Explanation:
This is because for A, this statement says nothing about corundum being yellow which means that this doesn’t apply and is incorrect. For B is pretty much the same as A, this statement about corundum doesn’t say anything about it being able to flavor or being flavorful. Lastly for D, the fact that corundum is hard means it would be impractical and probably impossible to use it as pencil lead because, all lead it doing with a pencil is being crushes and ground into the paper as you write.

How does competition affects behavior of species
Answer:
The way organisms compete with each other determines species distributions, population dynamics, community structure, food webs, and social dominance hierarchies. ... These stressors affect the way that organisms compete with each other and their ability to survive and co-exist.
Explanation:
A population of tree frogs living in the Amazon rainforest have two skin color phenotypes controlled by the same gene. Hozygous dominant and heterozygous individuals have green skin while hozygous recessive individuals have blue skin. In the first generation, analysis of the alleles for this gene shows that 70 alleles of this gene are green, and 130 alleles of this gene are blue in the population. In the second generation, 90 alleles are green and 110 alleles are blue. Finally, in the third generation, 120 alleles are green and only 80 are blue. Based on this data, which description best describes this population of tree frogs?(1 point)
A) The green skin color is being selected over blue skin color.
B) The frogs are randomly mating with each other.
C) The population size of frogs is very large.
D) There are no individuals migrating into or out of the population.
Answer:
A
Explanation: You can see that the green colored frogs were once lower than the blue and as time started progressing the green started getting a higher population over the blue, as the blue decreased.
For the frogs, the green skin color is being selected over blue skin color. This leads to the abundance of the skin color in the third generation.
What is natural selection?
Natural selection refers to a situation in which traits that enable organisms to better survive and adapt in their habitat tend to persist whiole other traits gradually disappear.
In this case, we can say that the green skin color is being selected over blue skin color.

__from farmland is often contaminated with pesticides, herbicides,
fertilizers, and oils used in farm equipment.
A. ammonia buildup
B. runoff
C. livestock
D. acid rain
Answer:
B. Runoff
Explanation:
A farmer often sprays a certain kind of insecticide, a chemical that kills insects, on his plants to prevent locust bugs from eating all of his corn crops. One day there was a random change in the sequence of DNA in a locust egg cell. When the egg cell hatched, the locust was resistant to the insecticide (it would not be killed by it). Since that locust could survive and reproduce, natural selection occurred until the entire population evolved to become resistant.
A) Identify the variation that existed in the insect population. _________________________________
B) Identify the process that created this variation. _________________________________
C) Explain why the variations in the insect population would be passed on to the next generation.
D) Is this locust population likely to survive, why or why not?
Answer:
as they were living in that environment they adopted it and were able to in it ; the population was able to survive because they adopted it
Which structure in the heart'separates
oxygenated blood from deoxygenated blood?
Answer:
pericardium
Explanation:
A double-walled membrane, the pericardium, separates the right and left chambers, preventing oxygen-rich blood from mixing up with the one without oxygen. So, the heart functions go smoothly. Deoxygenated blood enters the right atrium.

What effect would building a highway have on an ecosystem?
A) increase in butterfly migration
B) Decrease in destruction of a habitat
C) Increase in carbon dioxide
D) Increase in oxygen
Answer:
C
Explanation:
Building a highway destroys an ecosystem/habitat, so not b. With the ecosystem destroyed there will be a reduced number of trees that produce oxygen, so not d. Now you make an educated guess. If there is a large highway there will be a lot of cars which produce lots of carbon dioxide. No butterflies.

When thinking about genotypes and phenotypes, which is the cause and which is the effect?
Answer:
A particular genotype does not necessarily guarantee a particular phenotype. Understanding what factors can change this expression is quite complex.. What is what i believe that above statement meant.
Explanation:
Error is the stochastic variation associated with a particular observation of the phenotype (and is managed by use of replication and and appropriate experimental design). The phenotype is the result not only of the average effect of the different alleles at a given locus across test units and across environments, but is impacted by the interaction between the different alleles and the environments (including genetic backgrounds) in which they are evaluated. Phenotype is not simply the sum of the genotype effect and the environment effect, as indicated in the mathematical formula that you provide.
