The diagram below shows a light ray striking Medium A and Medium B at the same angle. (4 points)

A rectangle labeled Medium A is drawn on the left. A ray of light travels through air and strikes the surface of medium A making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium A and makes an angle of about 15 degrees with the vertical. A rectangle labeled Medium B is drawn on the right. A ray of light travels through air and strikes the surface of medium B making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium B and makes an angle of about 25 degrees with the vertical.

Which statement is correct?
The speed of the light ray is the same in air and Medium A.

The speed of the light ray is the same in air and Medium B.

Which is an environmental factor that affects skin color in humans?
O number of genes inherited
O amount of sunlight absorbed
O number of linked genes
O amount of food consumed

Answers

QUESTION:-

Which is an environmental factor that affects skin color in humans?

O number of genes inherited

O amount of sunlight absorbed

O number of linked genes

O amount of food consumed

ANSWER:-

AMOUNT OF SUNLIGHT ABSORBED.

Number of gene for color of the skin is same in all the human beings and also it's a genetic factors is there will be any absence of gene due to its deletion AMOUNT OF SUNLIGHT it is variable in variable reasons which is a imp factor for the color in variation in earth. In regions near to the equator have high amount of the light so they have darker skin color then the people near the poles as there is less amount of light .Number of gene inherited is also same for each and every individual for single species for human which is 378 gene loci and if there is any variation in number due to any genetics disorder it would be a genetic factor again.amount of food consumed is different for different people with same color in same region as it only depends on the work which is done by the individual in the society for its existence. though it is a environmental factor bit it didn't effect color of the species.

SO ACCORDING TO ABOVE DETAILS WE CAN CONCLUDE (2) AMOUNT OF THE SUNLIGHT IS THE ENVIRONMENTAL FACTOR WHICH IS RESPONSIBLE FOR THE COLOR OF THE SKIN IN HUMANS

What goes on during interphase?

Answers

Explanation:

During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). ... Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions.

Explanation:

During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The cytoplasm is usually divided as well, resulting in two daughter cells

B. Antibiotics treat the symptoms, and antivirals destroy the causing organism.

C. Antibiotics are in liquid form, and antivirals are in mist form.

D. Antibiotics treat patients who have Staphylococcus, and antivirals treat patients who have the flu.

The answer is D

Explanation:

Specific drugs are used to curb infection or diseases caused by specific pathogens. An infection can be caused by either bacteria, virus or fungi. Considering their different mechanism of infection, viral infections are treated with the use of ANTIVIRAL DRUGS while bacterial infections are treated with the use of ANTIBIOTICS.

According to this question, staphylococcus is a bacterial genus and hence, patients with staphylococcus can be treated with antibiotics while flu is a viral disease, hence can only be treated with antivirals.

Write down the functions of
1.microtubules
2.tripletsof microtubules

Answers

Answer:

Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility

Centrioles are cylindrical structures that are made up of protein tubes called microtubules. Specifically, nine groups of three microtubules, known as triplet microtubules, are linked together to make the walls of the cylinder.

Hope it helps :)

Answer:

Microtubules have several functions. For example, they provide the rigid, organized components of the cytoskeleton that give shape to many cells, and they are major components of cilia and flagella (cellular locomotory projections). They participate in the formation of the spindle during cell division (mitosis).

triplet microtubules are linked together to make the walls of the cylinder.

During a recent hurricane, 25 individuals of the same butterfly species were blown onto a barrier island in southern Florida. Prior to this event, this species did not inhabit the island, but with the ample vegetation on the island and a lack of predators, the displaced individuals were able to survive and reproduce. When the butterflies initially arrived on the island, they did not have to compete for food or space. What type of population growth did they likely exhibit

Answers

Answer: Exponential

Explanation:

The main requirement for the population of a species to grow is food. When there is food, a organisms that are born will be able to live longer because food will be able to sustain them.

This is what happened with humans during the Neolithic Revolution when we began farming.

The general trend is that the more food that is available, the higher the population growth. When these butterflies arrived and found no competition for food, their population would increase in the highest way possible which is exponentially because there would be plenty of food to go around.

Answer:

Exponential growth

Explanation:

Without any competition for food or space, the butterfly species likely experienced exponential growth.

The lack of competition would have allowed the population to flourish, as they would have excess amounts of resources, food, space, and other limiting factors.

So, they most likely exhibited exponential growth.

When can exponential growth happen?

O A. When there are limited resources

O B. When the death rate is high
Han

O C. When carrying capacity is reached

O D. When there is no competition

Answers

Answer:

D. When there is no competition

Explanation:

If there is no competition in a population, exponential growth can occur.

Without competition, resources are not limited and a population can grow rapidly.

With limited resources, a high death rate, and a reached carrying capacity, population growth is strongly limited and cannot grow at an exponential rate.

So, answer choices A, B, and C are all incorrect.

The correct answer is D. When there is no competition

Explanation:

Naturla selection is the survival and reproduction of individuals due to different phenotypes. The naturla selection represents a mechanism of evolution and changes in traits of species.

In order for natural selection to occur, organisms must :

have a variation that can be passed from one generation to the next.have differential reproductive success.

Natural Selection is a mechanism of evolution that occurs when there is a heritable variation for a trait and individuals with one version of the trait have greater reproductive success than do individuals with a different version of the trait.

In order for natural selection to occur, three conditions must be met:

There must be variation for the particular trait within a population.The variation must be inheritableIndividuals with one version of the trait must produce more offspring than those with a different version of the trait.

Thus,

In order for natural selection to occur, organisms must :

have a variation that can be passed from one generation to the next.have differential reproductive success.
