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.

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

in recent years much of califorinia has had drought conditions much of our food comes from califorinia and there are many growing cities in that state what do you think has happened to the ground water supply as droughts have occured there explain how a diversion system could be useful califorinia including the parts of such a system
Answer:
The level of ground water decreases.
Explanation:
Due to drought condition, the level of ground water decreases because of pumping of water for the irrigation purpose. Huge amount of water is required to irrigate a large area of California and in the drought conditions ground water is the only solution for this problem. The diversion system will be useful California by diverging river into these drought affected areas in order to fulfill the need of water for growing crops so we can conclude that this diversion system helps to fulfill the necessity of water during drought situation.

How is phylogeny related to classification?
Answer:
Most modern systems of classification are based on evolutionary relationships among organisms – that is, on the organisms' phylogeny. Classification systems based on phylogeny organize species or other groups in ways that reflect our understanding of how they evolved from their common ancestors.

what is photolysis? Define it.
Answer:
i think you meant to type photosynthesis? If not, please comment it so i can edit my answer
Explanation:
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Producers used photosynthesis by getting energy from sunlight. Photo basically means light and synthesis means produce.
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.

Climate change could mean global warming and deforestation. Deforestation means less transpiration which leads to more droughts and less habitats. This could make animals or plants endangered or extinct.
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.

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.

i need the answer to the last question
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.
The best measure of relatedness is the underlying genomic DNA.

Stromatolites contributed oxygen to the early atmosphere through photosynthesis.
What are stromatolites ?Stromatolites are layered sedimentary formations that are created mainly by photosynthetic microorganisms such as cyanobacteria, sulfate-reducing bacteria, etc. that lives today in a wide range of environments ranging from the shallow shelf to lakes, rivers, and even soils.
Cyanobacteria were ultimately responsible for one of the most important global changes that the Earth has undergone. Being photosynthetic, cyanobacteria produce oxygen as a by-product.
