Answer 1

Answer:

Option A) is correct.

Explanation:

Electromagnetic waves refer to waves that are created due to vibrations between a magnetic field and an electric field.

How is your body temperature held constant despite different weather temperatures
outside?​

Answers

Answer:

Core body temperature The body can only stay at a constant temperature if the heat generated is balanced and equal to the heat lost. Although the core temperature must be close to 37°C, fingers and toes can be colder. This is because energy is transferred from the blood as it travels to the fingers and toes.

Answer: When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.

During his voyage on the HMS Beagle, Darwin observed the
beaks and behavior of finches. These finches were similar
in some ways to the single finch species that existed on
the mainland of South America. On the Galápagos Islands,
however, there were 13 different species, each with
different beaks and different diets. Later, Darwin
hypothesized that natural selection could explain the
differences in the finch species. Many years later,
Rosemary and Peter Grant of Princeton University began to
test Darwin's hypothesis.
Scientists have recently developed a hypothesis based on
evolutionary concepts and the Grants' work. First, finches
from South America arrived on one of the islands. Then,
the finches that arrived on the island had to survive in a
new environment. The plants on the island were different
from the plants on the mainland. As a result, the
population on the island evolved differently from the
population on the mainland.
Later, a few finches from the island may have flown to
another island and begun the speciation process again.
This process may have been repeated many times. Now
there are 13 distinct species.

You are replicating Gregor Mendel's famous experiment with sweet peas. The genotype for dominant smooth-seeded parent is designated AA, while the genotype for the wrinkled-seeded parent is aa. Using a punnet square predict the first generation for this cross. What are the genotypic and phenotypic ratios? SHOW ALL WORK.

Answers

Answer:

The correct answer is -

A. genotype ration = 1/1 or 100% of Aa.

B. phenotype = all smooth-seeded.

Explanation:

According to the question, in this experiment, the smooth seed is the dominant trait over the wrinkled seed. The wrinkled seed is recessive, therefore, represented by aa and dominant is represented by AA

gametes: A and A from smooth seeded parent and a and a from the wrinkled-seeded parent.

Punnett square:

       A          A

a      Aa       Aa

a      Aa       Aa

In this cross of F1 generation, all the offsprings are Aa in genotype 4/4 or 1/1 or 100 percent chances.

And phenotypically 100% chances of the smooth seed plants.

Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.

Use the scenario to answer the following question. A forest ecosystem is home to mountain lions, coyotes, bobcats and deer. The deer eat grass. The mountain tions, coyotes, and babcats eat deer. Hunters began killing large numbers of mountain lions, coyotes, and bobcats. About twenty years later, the deer population had largely increased. The teacher asked the students to explain why the population of deer had a large increase in population size. Which student's argument MOST accurately explains the increase in the deer population? A Student 4: The deer population increased because with fewer mountain lions, coyotes, and babcats there was less competition within the deer population. B. Student 1The number of deer increased because deer populations are always increasing, even when there are mountain lions, coyotes, and bobcats preying on them. Student 3: The number of deer increased because with fewer mountain lions, coyotes, and bobcats, the deer had more food available to eat. D Student 2: The number of deer increased because without mountain , coyotes, and bobcats, the deer longer and had more offspring that also lived longer,

Answers

Answer:

A. student 4

Explanation:

The population of deer increase because with fewer mountain lions, coyotes and bobcats there was less competition within the deer population

The correct statement is that; The number of deer increased because without mountain , coyotes, and bobcats, the deer lived longer and had more offspring that also lived longer."

What is food chain?

The food chain describes the feeding relationships that exists in nature. Now this ecosystem has the food chain; grass ---> Deer ----> babcats ---> coyotes  ----> mountain lions.

Now we are also told that the mountain lions eat the the bobcats and the hunters are killing the mountain lions, coyotes, and bobcats, the predators of the deer hence been removed hence the deer population multiplies.

Therefore, the correct statement is that; The number of deer increased because without mountain , coyotes, and bobcats, the deer lived longer and had more offspring that also lived longer."

A population ecologist wished to determine the size of a population of white-footed deer mice, Peromyscus leucopus, in a 1-hectare field. Her first trapping yielded 80 mice, all of which were marked with a dab of purple hair dye on the back of the neck. Two weeks later, the trapping was repeated. This time 75 mice were trapped, out of which 48 of the mice were marked. Using the formula below, what is the population of mice in the field

Answers

Answer: 125

Explanation:

Population size is the number of individuals in a population. First, the trapping yielded 80 mice that were marked. Two weeks later, 75 mice were trapped and 48 of them had the mark.

The formula used for this question is:

N=mn/x

N= population size in the 1-hectare field. m= number of individuals marked and released the first time. n= number of individuals captured the second time. x= number of marked individuals that are recaptured.

The experiment consist on a randome collect sample of individuals which are then marked and released.  Next, take a sample again.

So, replacing the values we get:

N=(80)(75)/48

N=125 individuals.
