Describe the changes that a country undergoes as it passes through the three stages of the demographic transition. Use the United States as an example.

Answers

Answer 1

In stage 1, both birthrate and death rate are high, and the population grows slowly. Stage 1 describes the US for the early years of history. Then during Stage 2, improvements in health care, sanitation, and nutrition all people to live longer and reduce the death rate. The birthrate however, remains high during this stage so the population increases rapidly. This occurred in the US in the 1800s. Eventually, birthrate decreases to match the low death rate and the population growth slows and eventually stops. This is the US today.

Why does a plant-based diet require fewer resources to produce? Do you think people should eat less meat? Why or why not?​

Answers

Answer:

I think that they are both equally nutritious and that they give us the nutrition that we need. a plant- based diet uses less resources because they use less water to produce the food as it suppress all animal based products. I think people should eat less meat because sometimes people put unhealthy chemicals in food that can be harmful and not healthy as a source to people.

b. seed tree cutting
C. group selection
d. single tree selection

Answers

Answer:

C. group

Explanation:

Removing a specific group of trees within a small area over a long period of time is group selection. The correct option is C.

What is group selection?

A quantitative definition of group selection is when the average group fitness is greater or less than the mean of the fitness values of the individual members.

Another definition of group selection is when features evolve in accordance with the fitness (survival and reproductive success) of groups.

The conclusion was that although group selection is theoretically feasible, in practice it almost always favors one group over another.

Group selection is the long-term removal of a certain group of trees in a constrained region. In a clearcut, all the trees in a specific region are taken out at once.

The removal of shelterwood cutting clears an area's also clears land cleared for shelterwood cutting, which also involves cutting downing shelterwood cutting, but it is a completes a method of clearing

Thus, the correct option is C.

On a scratch sheet of paper, complete the Punnett square of the cross between two heterozygous red-eyed flies (Rr). What color eyes will the offspring have?

Answers

Answer:

75% red, 25% other color (brown?)

Explanation:

A cross between two heterozygous red eye flies (Rr x Rr)

                     R                     r

R                  RR                   Rr

r                   Rr                   rr

The possible genotypes are RR, Rr, and rr. There are two possibilities of Rr.

Since the heterozygotes have red eyes, the red eye allele must be dominant. Therefore, RR and Rr genotypes will all have red eyes. That means 3/4 (75%) of offspring will have red eyes. 1/4 25% are h0m0zygous recessive (rr), and will therefore have the other eye color (question doesn't mention which colour this is, it is likely brown)

How many chromosomes will be found in
each of the two new cells formed as a result
of mitotic cell division?

Answers

At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

23 pairs of chromosomes will be found in each of the two new cells formed as a result of mitotic cell division.

WHAT IS MITOSIS:

Mitosis is a kind of cell division that results in the formation of two daughter cells with the same number of chromosomes as the parent cell.

Mitosis is used for growth and tissue repair in living organisms. In mitosis, a parent cell divides into two new daughter cells, however, each cell possess the same number of chromosomes as the parent.

In a somatic human cell, there are 23 pairs of chromosomes (46 chromosomes). If this cell undergoes mitotic division, then, there will be 23 pairs of chromosomes in each cell formed.

Answers

Answer:

instinct=migration

trial and error=putting a puzzle together

conditional response=getting hungry before lunch time

habit=brushing your hair

reflex=eye blinking

I hope this helped and was explained better

The behavior type of response with the corresponding action is instinct-migration, trial and error-putting a puzzle together, conditional response-getting hungry before lunchtime, habit-brushing your hair, and reflex-eye blinking.

What is the corresponding action?

The brain control action is regulated by the body some are involuntary and others are voluntary it creates a rhythm in our body to make the system regulate.

Migration is instinct but putting puzzle is a trial and error condition, when the eye is blinked is a reflex action, and crushing your hair is a habit while getting hungry before lunchtime is a conditional response.

All the action of the body is controlled by the body's action some signals are sent to the body to regulate every action to control conditional response or habit.

Therefore instinct-migration, trial and error-putting a puzzle together, conditional response-getting hungry before lunchtime, habit-brushing your hair, and reflex-eye blinking.
