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

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

why does a male body produce more testosterone than a female's body
Answer:
Levels depend on a person's age, sex, and health. Males usually have much higher levels of testosterone in their body than females
Explanation:
As the metabolism of testosterone in males is more pronounced, the daily production is about 20 times greater in men. Females are also more sensitive to the hormone

The government wants to set new regulations that prohibit chlorofluorocarbons (CFCs) use in aerosol sprays and refrigerants. How will this act help with the sustainability of our environment?
Answer:
The new regulation will help reduce the amount of green house gases available in the atmosphere thereby saving our environment from the Green house effect
Explanation:
Chlorofluorocarbons are examples of greenhouse gases which contribute to the Green house effect been experienced in our environment, by destroying the earths' Ozone layer
If the Government sets a new regulation that prohibit its use in sprays and refrigerants it will help reduce the amount of green house gases available in the atmosphere thereby saving our environment from the Green house effect
Answer:
that act will help the sustainability of out environment because : C. It will slow down the degradation of the ozone layer
The usage of CFC will crate chlorine atoms that catalyze ozone degradation. By prohibiting this product, Government will slow down Ozone's degradation

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.
What is the difference between the original strand of DNA and the mutated
strand?
(HELPP)
Answer:
An original section of dna has the base sequence agcgttaccgt. A mutation in this dna strand results in the base sequence aggcgttaccgt. This change represents a frameshift mutation. It is a genetic mutation caused by indels (insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three.

one is a mutant

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

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.

Each kidney contains ____ of nephrons. Each is _____ but extremely _____, much like a neuron(but shorter).
Answer:
One million.
Explanation:
Each kidney contains about one million of nephrons. The nephron is the structural and functional unit of the kidney means that our kidney is made up of nephrons. The main function of nephron is to produces urine in the process of removing waste, toxic and excess substances from the blood. kidney is responsible for the filtration of blood by removing all the waste materials and taken these waste materials to the excretory organs in order to remove from the body.
How do toothed whales produce echolocating sounds?
Answer:
Toothed whales (including dolphins) have developed a remarkable sensory ability used for locating food and for navigation underwater called echolocation. Toothed whales produce a variety of sounds by moving air between air-spaces or sinuses in the head.
Explanation:
Answer:
Toothed whales can direct sound by bouncing it off air sacs in their nose and possibly by using face muscles to alter the shape of the melon.

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.
