How does biological evolution work?

Answers

Answer 1

Answer: It uses natural selection to choose traits that are more favorable which is measured by if the species can make fertile offspring. For example horses can make fertile offspring like donkeys can also do this but a cross betweek male donkeys and female horses can make offspring(mule) but not fertile ones. Fertile offsprings are offsprings/ kids that can have kids.

The table below shows the average monthly temperatures of four locations.
Based on the table, which of these locations is most likely situated near the ocean? (4 points)
Location A
Location B
Location C
Location D

Answers

Answer:

Location A

Explanation:

Coastal areas have milder temperatures since they are close to water and water retains heat better than land (it's harder to warm it up and harder to cool it down). Due to this property of water, the location with the least temperature fluctuation would be the answer. Location A has the smallest range between the highest and lowest annual temperatures, making A the best answer choice. I hope I helped and that it's not too late for you.

Reasons why the queen is the most important in the hive.
(No LINK)

Answers

Answer:

I assume you are referring to bees?

Explanation:

From what I know and this is just surface level knowledge, she is the one who births the hive and usually designates their purpose once she has laid the eggs. She herself does not do much, she is just the one that the infrastructure of the hive follows in maintaining the hive itself. I hope this helps. Good luck!

The Queen Bee plays a vital role in the hive because she is the only female with fully developed ovaries. The queen's two primary purposes are to produce chemical scents that help regulate the unity of the colony and to lay lots of eggs.

native organisms in the area?
O A. The population will increase.
OB. The population will decrease.
C. The population will experience no change.
D. The population will decrease, then slowly increase.

Answers

Answer:A

Explanation:

Because n

Answer:the answer is B.the population will decrease.

Explanation:

The population will decrease because since the grassland is turning into a desert due to overgrazing, it will be causing the grass to die out, and since the grass is dying out, the grass eating native organisms population will start to go down as well because there will be no more grass to eat from, so therefore i think the answer is B. The population will decrease.

During normal mitotic cell division, a parent cell having forty-six chromosomes will produce two daughter cells, each containing what?

Answers

Answer:

46

Explanation:

This is because mitosis is a type of cell division where a parent cell divide into two daughter cells that are genetically identical to the parent cell i.e the same number of chromosomes is replicated or copied to the two daughter cells. Each daughter cells will carry the same number if chromosomes as the parent.

Therefore from the question, the daughter cells will have 46 chromosomes each as the parent.

Answer:

C. Pp, purple

Explanation:

P (dominant) = purple

p (recessive) = white

Capital letters are dominant, while lowercase letters are recessive. For a recessive trait to be expressed, there needs to be 2 of that allele (in this case two p alleles need to be expressed for the flower to be white). The question asks for a dominant allele and a recessive allele, so the answer must have P and p. Pp is the genotype of the plant, while purple is the phenotype. The genotype is the genetic makeup, while the phenotype is the physical appearance of the plant. In this instance, the flower will be purple because purple is dominant over white which is recessive

There are plenty of resources.
No predators are present.
There are no resources.

Answers

Answer:

There are plenty of resources.

No predators are present.

Explanation:

There r plenty of resources + no predators

Exponential population growth happens when there are plenty of resources and no predators are present.

What do you mean by Population growth?

Population growth may be defined as the change in population per unit of time.

Exponential growth occurs in the population of continuous breeders. For example, some insects, humans, bacteria, etc.

Exponential population growth requires an enormous amount of resources in habitat and no predator influence.

Therefore, exponential population growth happens when there are plenty of resources and no predators are present.

What provides energy to muscles and helps keep
them strong?

Answers

Answer:

The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body's biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells. So once muscle contraction starts, the making of more ATP must start quickly.

Answer:

adenosine triphosphate (ATP)

Explanation:

Creatine phosphate can supply the energy needs of a working muscle at a very high rate, but only for about 8–10 seconds.
