Which of the following conditions are required for natural selection?
I. overproduction of offspring
II. competition for resources
III. genetic variation
IV. natural disasters
Answer:
I. overproduction of offspring
Explanation:
Overproduction of offspring is the idea that species produce far more offspring than an environment can support because most of the juveniles will not make it to adulthood. This allows only the fittest to survive and reproduce.
Answer:
overproduction and offspring& genetic variation

Which two processes are involved in mitotic
cell division?
nuclear duplication and cytoplasmic
division
B nuclear duplication and cytoplasmic
duplication
C. spermatogenesis and cytoplasmic
duplication
D. oogenesis and cytoplasmic division
Answer:
A. nuclear duplication and cytoplasmic division
The two processes are involved in mitotic cell division include nuclear duplication and cytoplasm division.
Mitosis produces two identical daughter cells and is an asexual reproductive process which takes place during cell growth processes such as nuclear duplication and cytoplasm division.
Spermatogenesis and oogenesis are examples of sexual reproductive processes which involves the production of sperm and egg cells respectively. This makes them fall under meiosis and not mitosis.

Meiosis is an example of which type of process? A. asexual B. sexual C.generic D. somatic
Sexual reproduction includes meiosis, gamete production occurs during meiosis (eggs and sperm), hence option B is correct.
What is sexual reproduction?Meiosis specifically produces novel genetic material combinations in each of the four daughter cells. These novel pairings are the consequence of DNA switching between linked chromosomes.
Meiosis specifically produces novel genetic material combinations in each of the four daughter cells.

Explanation:
Like most stars in our universe, the Sun is on the main sequence stage of its life. This means nuclear fusion reactions in its core fused hydrogen into helium. However, this process cannot last forever since there is a finite amount of hydrogen in the core of the Sun. Currently it has more than 72% hydrogen.

Ashley is charting the motion of her pet rabbit. The diagram below shows its position every 0.25 seconds.
Which of the following statements about the rabbit's motion is true?
A. The rabbit's speed is increasing through time.
B. The rabbit is moving at a constant speed.
C. The rabbit's position is not changing through time.
D. The rabbit's speed is decreasing through time.
Answer:A
Explanation:
its is
The rabbit's speed is increasing over time, and it is known as velocity. Therefore, option A is correct.
What is velocity?Velocity is a term used in physics to describe the speed of an object in a particular direction. It is a vector quantity, which means it has both magnitude (speed) and direction.
The formula for calculating velocity is:
Velocity = displacement/time
In other words, velocity is often used interchangeably with speed, which is also a measure of how fast something is moving. However, velocity specifically refers to the speed of an object in a particular direction, whereas speed does not take direction into account.
Thus, The statement which is true about the rabbit's motion is "the rabbit's speed is increasing over time". Therefore, option A is correct.

Answer:
Genetics is the study of the body's makeup
Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in organisms. Though heredity had been observed for millennia, Gregor Mendel, Moravian scientist and Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically.

pesticides are chemicals that are often sprayed on crops to kill plant-eating insects, preventing damage to the crops. WHile pesticides are effective initially, many researchers claim that any single pesticide will see reduced effectiveness in as little as ten to fifteen years. Which of the following best supports the claim by scientists that the pesticides will eventually lose their effectiveness?
A. Insects will evolve to avoid any plant sprayed with pesticides to increase their chances of survival.
B. Insects that are naturally resistant to the pesticide will survive and reproduce more than the insects that are sensitive to the pesticide.
C. The insects will build up a tolerance to the pesticides, and eventually the pesticide will not affect them.
D. The pesticides will increase the mutation rate in the insects, resulting in higher genetic diversity and higher survival rate.
Pesticides will eventually lose their effectiveness as the pesticides will increase the rate of mutation in the insects, resulting in higher genetic diversity and higher survival rates. So, the correct option is D.
What are Pesticides?Any chemical or substance used for destroying the activity of insects or other organisms harmful to cultivated plants or to animals is known as pesticides.
It has been observed by scientists that the pesticides will eventually lose their effectiveness because pests have developed resistance - a significant decrease in sensitivity to a pesticide. The pesticide that is sprayed on crops allows increasing the mutation rate in the insects leads to increases in genetic diversity as well as their survival rate.
Therefore, Pesticides will eventually lose their effectiveness as the pesticides will increase the rate of mutation in the insects, resulting in higher genetic diversity and higher survival rates.

Answer: 3. Structure is a better indicator of a relationship between two organisms because function can be caused by environment, not common ancestry. Structure is better than function because the structure is based on genetics. For example, the wings on a fly and the wings on a bird perform the same function, but their genetic bases are different. However, the wings on a bird and the arms on a primate are coded by similar genes even though the functions are different.

A 10-micrometer cell is viewed through a 10x objective and a 10x eyepiece. How large will the cell appear to the microscope user?
Answer:
A 10x Eyepiece magnifies 10 times; in other words, an object viewed through the eyepiece, in focus, will seem ten times larger than normal. ... In this case, a 10x Eyepiece and a 10x Objective Lens would combine to show a 100x image, or an image 100 times the actual size.
Explanation:
If a 10-micrometer cell is viewed through a 10x objective and a 10x eyepiece, the cell will appear 100 times bigger than normal to the microscope user.
Magnification is defined as the ratio of the image distance to the object distance.
Magnification determines the number of times an image is larger or smaller than the object.
If the magnification is greater than 1, it means that the image is enlarged but if the magnification is less than 1, the image is a diminished image.
According to the question, if a 10-micrometer cell is viewed through a 10x objective and a 10x eyepiece, the total magnification will be:
M = Mo × Me
M = 10 × 10
M = 100
This shows that if a 10-micrometer cell is viewed through a 10x objective and a 10x eyepiece, the cell will appear 100 times bigger than normal to the microscope user.
