The correct answers are:
-Genetic variation decreases in a population of prey after natural selection acts on it.
-Genetic variation exists in a population leading to individuals with adaptations with different survival frequencies.
Genetic variation creates new variants of a gene; such a variant is called an allele. These variations occur as a result of the interaction between individuals with their environment, where it affects them in a way that determines their survival or not, as a consequence of their adaptability to the surrounding context. Thus, natural selection occurs, which establishes which individuals survive and which individuals do not. Thus, individuals characterized as prey who develop defense elements against hunters will be the ones who survive, while those who do not will be the ones who will perish.

Photosynthesis stops due to the atmosphere filled with dust after a meteor strike on Earth. Why would the dust cloud stop photosynthesis?
The rays of sunlight has been obscured by the dust cloud thereby stopping photosynthesis.
Photosynthesis is defined as the process which green plants use in the production of their own food. in the presence of sunlight.
A meteor strike occurs when an extraterrestrial object such as an asteroid or meteoroid passes through the earths atmosphere or hits the earth. this can lead to the atmosphere being filled with dust especially when the incident hits the earth surface.
In the process of photosynthesis, the light stage depends on sunlight to take place.
Because the rays from the sunlight has been hindered by the dust after the meteor strike, the light stage of photosynthesis is inhibited (stopped). Therefore, photosynthesis cannot occur.

write two advantage from the study of life cycle of mosquito
Answer:
Knowing the different stages of the mosquito's life will help you prevent mosquitoes around your home and also help you choose the right pesticides for your needs, if you decide to use them. All mosquito species go through four distinct stages during their life cycle: Egg - hatches when exposed to water.
The two advantage from the study of life cycle of mosquito are:
•It enables us to have better understanding of the ways to reduce and prevent mosquitos bites.
•It helps us to go for the right mosquitos spray that will help in controlling the spread of mosquitos.
Mosquitoes is an insect that be found any where which is why preventing measure needs to put in place so as to avoid or prevent them from biting you skin so as to suck up blood or transmit virus.
Mosquitos are often very energetic especially at sunset to sunrise and they can be found at:
• Home
•Outside Home
•Where their is stagnant water etc
The disease or virus transfer by mosquitos is Malaria, this is cause by Anopheles mosquitoes as it tend to carry the virus in which after biting it victim it transfer the virus into the blood stream of the victim causing what is called Malaria .
Inconclusion The two advantage from the study of life cycle of mosquito are:
•It enables us to have better understanding of the ways to reduce and prevent mosquitos bites.
•It helps us to go for the right mosquitos spray that will help in controlling the spread of mosquitos.

The optic nerves pass through the ----- of the ------- bone.
Answer:
sphenoid bone
Explanation:
Extracranial. The optic nerve is formed by the convergence of axons from the retinal ganglion cells. These cells in turn receive impulses from the photoreceptors of the eye (the rods and cones). After its formation, the nerve leaves the bony orbit via the optic canal, a passageway through the sphenoid bone.

B) Carbon dioxide levels and temperature changes are direct related in the studies.
C) Studies show that atmospheric carbon dioxide has increased over the past 150 years.
D) The distribution of many organisms has already shifted as a result of warming.
Answer: D: The distribution of many organisms has already shifted as a result of warming.
Explanation: I just took the quiz on FLVS
The statement that supports the biological predictions as it relates to change in climate is : ( D ) The distribution of many organisms has already shifted as a result of warming
What is climate change ?Climate change is the long term change in the Average weather conditions of a region, province or territory. Climate change is associated to global warming caused by the activities of man which affects the weather conditions of a given region in the long term.
As the climate continues to change, many organisms begin to redistribute themselves to regions with favourable weather conditions, and this is the biological prediction/effect of climate change on the environment.
Hence we can conclude that The distribution of many organisms has already shifted as a result of warming is the correct statement.

how does the liver help in maintaining homeostasis
Answer:
The liver plays a major role in blood glucose homeostasis by maintaining a balance between the uptake and storage of glucose via glycogenolysis and gluconeogenesis. The liver is the primary organ for glucose metabolism.
Glycogenolysis: Glycogenolysis is the biochemical pathway in which glycogen breaks down into glucose-1-phosphate and glycogen.
Gluconeogenesis: Gluconeogenesis is the synthesis of glucose from non-sugar precursors, such as lactate, pyruvate, and the carbon skeleton of glucogenic amino acids.
if your leg was to get cut off where would you feel the pain?
The thigh area will feel much more pain as when leg is cut off , all nerves are together in thighs, so more pain will be there.
Hope it helps you... pls mark brainliest if it helped you
Answer:
The nerve(s) in your leg.
Explanation:
It's not your leg that will hurt but the nerve in your leg. So wherever the leg is cut, the nerves will have to be cut as well, but also after one of your limbs is amputated, you may feel like the limb is still there. That's called phantom sensation. You might feel pain in your limb even though it is physically not there.

por que un globo con aire se agranda al sol y se achica en la heladera
Answer: El globo congelado se contrajo porque la energía cinética promedio de las moléculas de gas en un globo disminuye cuando la temperatura disminuye. Esto hace que las moléculas se muevan más lentamente y tengan colisiones menos frecuentes y más débiles con la pared interior del globo, lo que hace que el globo se encoja un poco.

Proteins can be denatured in many ways.
Which of the following will NOT denature
a protein?
A. pH
B. temperature
C. too many enzymes
D. salt content
Answer:
Explanation:
However, at very high salt concentration, the increased surface tension of water generates a competition between protein and salt ions for hydration. Salts strip off the essential layer of water molecules from the protein surface eventually denaturing the protein
Too many enzymes cannot denature protein.
Enzymes are a type of protein so they will not get denatured in presence of one another.Enzymes are proteins that speed up any biochemical reaction in the body.What is denaturation of protein?It is a process of modifying the molecular structure of a protein.It involve breakage of many of the weak bonds within the protein molecule that are responsible for the structure of protein and its order.It can happen due to high temperature, pH, salt concentration and mechanical concentration.To know more about denaturation of protein here
