Answer:
Mitosis
Explanation:
Mitosis is the process in which new cells are formed from older ones by equational division in which ploidy of the cell (chromosome number) remains the same.
which of the following kinds of cells perform basic functiona as obtaining energy from food
Answer:
Both plant cells and animal cells.
Explanation:
This is due to the requirement for survival in both plant and animal cells, which provides movement and work energy to food.
Other possibilities are not correct, as either cell or none of them acquire food energy is false.

What is a hypothesis
A hypothesis is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories.
A hypothesis is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it.
Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Hypothesis Daily exposure to the sun increases levels of satisfaction. In this case, the independent variable and attributed cause is sun exposure. Happiness level is the regression coefficient and the assumed effect.
Simply expressed, a hypothesis is a descriptive method that also identifies the expected or predicted result of the study. Without a working hypothesis, no scientific experiment or investigation can be carried out.

What is the role of berries in plant reproduction? Fill in the blanks to summarize their function
For the berries to grow, a pollinator must first visit
plant's flower. It spreads the

long-spined sea urchins in 1983, set the Sea urchin infection rate to 90% How do you think this will affect
the reef?
I NEED IT NOW PLEASE AND THANK UU
Answer:
More number of algae is present on coral reef.
Explanation:
The population of algae present on the coral reef highly increases because the sea urchin feeds on the algae present on the coral reef. Sea urchin abundance of species populations is very important for coral reefs as a counterweight. It acts as a balancer of coral reefs due to the sea urchins themselves which generally eat algae found on coral reefs so if sea urchin population decreases, the algae present on coral reef increase in population.

Explanation:
Im really struggling with this project can someone please help?
Answer:
1/2 or 50% for each.
Explanation:
I just spent 20 min writing my in-depth answer and it did not save, so sorry for the short-cut answer:
After producing a cross, the results are Mm, Mm, mm, mm. 2/4 are Mm and the other 2 are mm. This means each have a 1/2 chance or 50% probability of being found in the offspring.
For #3, a rec phenotype is only displayed when the actual rec genotype is expressed (mm, in this case). So, the probability for this scenario would also be a 1/2 chance or 50%.
It was being weird and wouldn't let me type some of the words out for some reason, sorry! Hope this helps, anyways! Have a goodnight!1. How are seasons connected to the annual CO2 cycle?
CO2 in the atmosphere decreases during the growing season and increases during the rest of the year, which leads to maximum buildup in April and May before photosynthesis begins to take over again.
There's more carbon dioxide in the winter and a bit less in the summer. That's the collective breathing of all the plants in the Northern Hemisphere. "Plants are accumulating carbon in the spring and summer when they're active, and they're releasing carbon back to the air in the fall and winter," Graven explains.
3. Describe the changes that take place during the menstrual cycle from day 1-4 in the eggs in the overys
Answer: The average length of the menstrual cycle is 28–29 days,
Explanation:
but this can vary between ... Both pads and tampons need to be changed regularly (at least every four hours). ... Ovulation is the release of a mature egg from the surface of the ovary. This usually occurs mid-cycle, around two weeks or so before menstruation starts.

The stomata of plants are responsible for allowing water to escape through the leaf of a plant. Which of the following would you expect to observe under a microscope in a leaf that was picked during a rain storm in Houston? A. There would be a larger amount of closed stomata to prevent the loss of water through transpiration. B. There would be a larger amount of open stomata to allow the loss of water through transpiration. C.There would be a larger amount of closed stomata to prevent the loss of water through absorption. D. There would be a larger amount of open stomata to allow the loss of water through absorption.
The correct answer is B. During drought, stomata can be closed to prevent excessive water loss through the process of transpiration.
Stomata are tiny pores or openings which are in plant tissue and they allow exchange of gas. They are found in the leaves of a plant.
Guard cells helps in the opening and closing of stomata. The pores allows in, carbon dioxide into the plant which is well known as needed during the process of photosynthesis.
They help in reducing water loss and that is why the leaves close when it is dry or hot. The closing and opening of stomata helps in the process of transpiration.

Is homosexuality natural?
Answer:
It really just depends on who you're asking this, too.
Whether it's your mom or your friend, they'd both would have different answers and perspectives to the response to this question. I'm not familiar with everything that goes on in the LGBTQ+ community because I'm not in it myself, but it's safe to say that we are who we want to be. And that is most definitely natural.

Explain why your skin feels hot when you have a fever. Multiple Choice Vasoconstriction of the vessels in the dermis is causing the body to lose heat, and blood flow from the deeper tissues to the skin is decreased. Vasoconstriction of the vessels in the dermis is causing the body to lose heat. Blood vessel dilation in the dermis is allowing increased blood flow from the deeper tissues to the skin.
Answer:
Blood vessel dilation in the dermis is allowing increased blood flow from the deeper tissues to the skin.
Explanation:
Our skin feels hot when you have a fever because of the process known as vasodilation in which the widening of blood vessels occurs that increases the blood flow. Due to this process, blood flow to the skin increases that causes the temperature to rise and as as result sweating as well as dehydration occurs in order to remove heat from the body. So we can say that vasodilation is responsible for the increase in temperature of our body.

help please TwT
Answer:
yes they do. the amount depends on what's used. solar panels take a lot of mining and causes a lot of pollution to make and isn't reliable for large scale power like the US. like in Germany, they either have energy droughts or have to sell excess energy at a net loss to other countries. the best cleanest energy we have now is nuclear and we can process nuclear waste into more nuclear energy until it's spent so much that we can just throw it out

c. Provide one possible explanation for the change in bird numbers and beak characteristics.
Answer:
Evolution
Explanation:
If there is an environmental stressor, then animals will evolve to overcome it.
Birds may begin producing more or fewer offspring depending on how much food is available. If there is more food available, birds will have more offspring. If there is less food available, birds will produce fewer offspring.
Beak characteristics change depending on food options, mating rituals, or environment. A bird will need a narrow beak for most bugs, but it will need a wider and stronger beak for nuts and seeds. A bird's beak may also be used to help interact with its environment. For example, a woodpecker has a strong narrow beak to help it break into tree bark to eat.
