How is a typhoon formed?
Answer:
A typhoon forms when winds blow into areas of the ocean where the water is warm. These winds collect moisture and rise, while colder air moves in below. This creates pressure, which causes the winds to move very quickly. The winds rotate, or spin, around a center called an eye.
Explanation:
Answer:
Compared to tropical cyclone, we have a few main requirements for typhoon development:
1. sufficiently warm sea surface temperatures,
2. Atmospheric instability,
3. High humidity in the lower to middle levels of the troposphere,
4. Enough Coriolis effect to develop a low pressure center,
5. pre-existing low level focus or disturbance, and
6. low vertical wind shear.

What factors limit population growth?
A garden contains 40 flowers, 30 of which are red. What is the frequency of red flowers?
Answer:
0.75
Explanation:
a frequency of 1.0 occurs when all the flowers are red
A garden that contains 40 flowers, 30 of which are red. Then, the frequency of red flowers is 75% of 1:3.
What is Frequency?Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as the temporal frequency for clarity, and is distinct from angular frequency. Frequency is usually measured in hertz (Hz) which is equal to one event per second.
Gene frequency is the fraction or percentage of a population which carries a particular allele at a particular gene locus. In this case, a garden has 40 flowers, in which 30 are red.
Therefore, the frequency of red flowers = Number of red flowers/ Total number of flowers
The frequency of red flowers = 30/ 40 = 75% or 1/3

Explanation:
What causes evolution to occur in organisms? Explain the process of evolution and how it is driven by various factors.
Answer:
Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift. This occurs because organisms with advantageous traits pass on more copies of these heritable traits to the next generation

How does the extinction of species affect humans?
A. Extinction generates new sources of medicine.
B. Extinction upsets the natural cycling of nutrients,
C. Extinction helps keep air and water clean.
D. Extinction makes the environment more pleasant.
Answer:
B. Extinction upsets the natural cycling of nutrients
The extinction of species affect humans as extinction upsets the natural cycling of nutrients. Therefore, option (B) is correct.
What do you mean by extinction of species?Extinction is the end of a sort of life form or of a gathering of sorts, normally an animal categories. The snapshot of annihilation is for the most part viewed as the passing of the last person of the species, albeit the ability to raise and recuperate.
As species go terminated, they are removed from the established pecking order. The animals that ate the species that has gone extinct must find new food or die. Other animal or plant populations could suffer as a result.
Habitat loss and degradation (primarily deforestation), overexploitation (hunting and overfishing), invasive species, climate change, and nitrogen pollution are the main modern causes of extinction.

why dont plants photosynthesise in the dark
Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.
The oxidation of water occurs during photosynthetic electron transport during the light reactions of photosynthesis. In the absence of a source of light energy (dark reactions have no direct requirement for light energy), oxygen is not produced.

Please help...Will mark brainiest....It is due and I need help
Answer:
Explanation:
For the 1st one with the Cheetah: It would be a long tail because it helps them balance when they turn. Sinch Cheetahs move extremely quickly they need a balance to ensure they don't topple over when they turn, this tail provides this balance.
For the 2nd one with the bear: Thick coats on a bare will help provide warmth whenever they go to hybernate. Thin fur would leave room for freezing and wouldn't be able to help them maintain the proper body temperature.
The 3rd one with the clownfish: A round tail provides a bigger boost when swimming since it is able to push more water. A forked tail would create a gap when they swim so they would have to expend more energy than with a round tail.
The 4th one with the Finch: Since grubs live underground a thinner beak would be able to dig them out and stab them faster. This allows them to reach farther and get more food.

Describe what it means when we say that DNA replication is semi-conservative:
Answer: Semi-conservative replication means that during DNA replication, the two strands of nucleotides separate. Both strands then form the template for free nucleotides to bind to to create the two identical daughter strands. Hence each daughter strand has half of the DNA from the original strand and half newly-formed DNA. brainliest

What are some ways that natural selection equips organisms for survival in their environment?
Answer:
Well organisms who have traits that are beneficial to them and would make them live long enough to usually reproduce, it would become an adaptive trait. That organism who has that trait will most likely live the longest and reproducing which will pass down their traits. Other same type of organisms who don’t have that trait will most likely die quicker then those who do and they won’t be able to pass on their genes which will lead to the natrual selection being very few of those types. If your born with a non useful trait, you jsut pass it down, you can’t just have the ones that benefit you unless yoru parents have it. This is why at the ”end” there will be more with useful traits and barley any with non.
