A. How are radio waves used to create radar maps?
B. How does reflectivity help meteorologists figure out the weather shown on
radar maps?
Answer:
A. These signals have been calibrated against actual visual and location readings for the amount of rain falling and cloud water content. ... Thus the computer generates a visual image according to the reflectivity of the amount of water in colors on a map.
B. Reflectivity of an object helps indicate the amount of water that a cloud may carry. The stronger the reflected signal from the radar signal sent out, the easier the meteorologist will be able to tell what to expect. ... This in turn is interpreted by the meteorologist from past experience as what to expect in the future.

if a cell is in a state in which it no longer divides then the cell is probably arrested at which stage of the cell cycle?
Answer:
Interphase
I
Explanation:
Interphase is the period of the cell cycle during which the cell is not dividing. The majority of cells are in interphase most of the time. Mitosis is the division of genetic material, during which the cell nucleus breaks down and two new, fully functional, nuclei are formed.

write the function of these in your body. carbohydrates, protein, vitamin
Answer:
Carbohydrates- is the main source of energy of your body. They help you fuel your brain, kidneys, heart muscles, and central nervous system.
Protein- A lot of your body is protein. Your muscles are just about all protein, and most of your organs are protein. Many of the chemical reactions in your body are speeded up by other types of protein. Your body can make some of the components of protein by itself, and it must get some of the components from outside of the body.
You need protein daily for your tissue to repair itself, normal function, and perhaps to grow.
Vitamin- Vitamins allow your body to grow and develop. They also play important roles in bodily functions such as metabolism, immunity and digestion.

Can sunlight change the distribution of traits in a population?(1 point)
No, because the environment can only change behaviors.
Yes, because the environment is the only factor that can change traits.
Yes, because the environment can factor into the distribution of traits.
No, because the environment can only change traits in individual organisms.
A number of factors including environmental factors (for example sunlight) can also play a role in how the traits in a particular population is distributed.
Sunlight can change the distribution of traits in a population because the environment can factor into the distribution of traits.
The distribution of traits is changed when factors in the environment change/evolve and influence natural selection. These environmental factors including sunlight alter the selection of traits passed to generations and can have an effect on the distribution of the traits on Earth.Learn more about environmental factors: https://brainly.com/question/3638961
The sunlight can be a factor for the distribution of traits in a population. Option C is correct.
Natural selection:
It is phenomenon in the evolution in which a population of species in distributed in the habitat or evolve by the certain traits that fits in the nature.
For example-
A population of a species have two types of traits,
1. Individuals that can bear the intense light.
2. Individuals that can not bear the intense light, prefer low light.
After several generation the whole population will divide in the groups according to their ability to bear the intensity of light.
It can also result in the new species that only wake up at night to avoid the sun.
Therefore, the sunlight can be a factor for the distribution of traits in a population.

why is it important for gametes to be haploid jiskha
Answer:
its important for gametes to be haploid so when fusion of the Male and female gametes take place after fertilization the correct amount of chromosome numbers specific to the species can be restored
It is important for gametes to be haploid as just to maintain the chromosomal number. It is present for the sake of incorporation of both of the sets of chromosome in the progeny.
What is the number of chromosomes in humans ?It is having 23 pairs of chromosomes that is having total of 46 chromosomes.
Because meiosis just creates cells which are destined to be the gametes and in this reduction in the chromosome number is just critical that is without the process, the union of the two gametes that are during the fertilization that will result in the offspring with just twice of normal number of the chromosomes.
Haploid cells in the humans are just produced out by meiosis. This is type of the cell division in which the single diploid parent cell just divides to just produce four with the non-identical type of the haploid daughter cells. In meiosis is just used to get the type of the produced type of gametes and is are a necessary kind of precursor to the sexual reproduction.
