The allele of the human transport protein associated with light skin is found almost exclusively in people with European ancestry. The other common allele for darker skin, which appears to be the ancestral allele, is found in people with African ancestry. What is a plausible explanation for how the lighter-skin allele came to be so common in those with European ancestry
Answer:
See Explanation
Explanation:
Darwin's theory of natural selection has it that organisms that are better adapted to their environment happen to survive and reproduce passing on their favorable characteristics to their offspring.
It must have been that a gene mutation occurred in the ancestors of the Europeans which led to the appearance of the allele for lighter skin.
This trait became favorable in their environment and people that had it were able to survive and pass the trait on to their offspring hence it became predominant throughout the population.

Answer:
Algae actively absorb carbon dioxide, and therefore reduce the greenhouse effect. Fuel from microalgae is called third-generation biofuel, and development for its production is currently underway. With sufficient information on the composition of biofuels, researchers can significantly improve production processes.
Explanation:
Interactions between organisms and their environment impact the organism’s overall population. The jaguar Panthera onca is the largest cat in North America. It is found in areas across the Southwest, including Arizona, New Mexico, and Texas. It is a carnivore that has powerful jaws and sharp teeth and preys on fish, turtles, and many smaller mammals. Which shows the relationship between the jaguar and turtles?
Answer:
The correct answer is - predator-prey
Explanation:
The relationship between predator and prey is the interaction between predator and prey. A predator is is an organism that lives on hunting down other organisms for their nutrition and energy while the prey is an organism that is getting killed or hunted down by a predator. The population of prey is controlled by predators.
Here, the jaguar depends for their nutrition and energy on turtle and other organisms, therefore, jaguar hunt the turtles for their food which makes this a predator-prey relationship.

Three common methods employed in the cleanup of oil spills are aeration of water, skimmer boats, and genetically engineered bacteria aeration of water, skimmer boats, and genetically engineered bacteria A aeration of water, phytoremediation, and genetically engineered bacteria aeration of water, phytoremediation, and genetically engineered bacteria B skimmer boats, high temperature incineration, and phytoremediation skimmer boats, high temperature incineration, and phytoremediation C large floating booms, high temperature incineration, and phytoremediation large floating booms, high temperature incineration, and phytoremediation D large floating booms, skimmer boats, and genetically engineered bacteria
Answer:
large floating booms, skimmer boats, and genetically engineered bacteria
Explanation:
Skimmers are used in the clean up of oil spills it makes use of containment skims that act like a fence and the surface of water and prevent the oil spill from moving or spreading across the water surface. It contains the oil into a particular place. Floating booms helps in the sucking out of oil in the confined area, its act like a vacuum pump and suck out all the oil spills available in the areas confined by the skimmers.
Bioremediation involves the use of microorganisms to clean up spills this micro organism breaks down this petroleum product into harmless substance through their metabolic activities. Genetically modified Bacterial can be use for this purpose to help break down this hydrocarbons and make them less toxic.

How can independent assortment help explain genetic diversity in humans? Hint: How many pairs of chromosomes are in a human diploid cell?
Answer:
please give me brainlist and follow
Explanation:
Independent assortment states that all alleles are inherited independently of other alleles. This helps diversity because it helps to further the randomization of traits. If traits were always inherited together, as a "package deal", there would naturally be less diversity than the situation that exists.

In the mouse model of malaria, the researchers injected Plasmodium-infected human red blood cells into the mice because the Plasmodium species had surface ligand proteins that bound only to cell membrane proteins of human red blood cells. Assume that the researchers noticed that some of the parasites no longer infected human red blood cells but instead infected mouse red blood cells. Predict the most likely cause of this change in the host specificity of the parasites. Plasmodium reproduces both sexually in the host vertebrate and asexually in mosquitoes. The researchers claim that the Plasmodium organisms that infect the two different types of red blood cells are likely to evolve into two separate species of Plasmodium. Based on the biological species concept, provide reasoning that would support the researchers’ claim.
Which of the following describe Aristotle's model of the solar system? Select the three correct answers.
Each planet spins on an epicycle.
The Sun is at the center.
The Earth was at a point slightly offset from the center.
The stars are attached to the outermost sphere.
Earth is at the center.
Each planet is attached to a crystalline sphere.
Answer:
The Earth is at the center
Explanation:
Aristotle was the first to believe the earth was round but he still thought everything revolved around the earth.
Aristotle's geocentric model of the solar system was based on the belief that the planet moves around the earth at the same speed.
One peculiar thing about this model was that the earth was said to be at the centre, which is why it is described as the geocentric model.
Some characteristics of this model include:

reproduce much more rapidly and grow much faster, causing a green "bloom” to cover the whole surface of the
lake. Which of the following is the most likely cause of this bloom"?
Answer: I think that it would be C because blooms are due to eutrophication, which means that there are high levels of phosphate in the water. Phosphate is a main ingredient in pesticides, which can run-off into rivers.
Someone suggested that everything to be sent to the base on the moon must be sterelized so that no bacteria of any kind are present.Do you think this is a good idea
Answer:
Yes.
Explanation:
Yes, it is a good idea by sterilizing everything because this sterilization process kills bacteria or other harmful microbes on the items and no chance of bacterial infection occurs in the base that is present on the moon. This sterilization process is very important in order to make the health of the crew members and scientists that lives in the base on the moon. If the bacteria or other harmful microbes enters in the base so its maintained environment will triggers its growth and infections in the humans so it is a good idea.

7. How do environment factors and genetic factors affect natural selection?
Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. 2. Adaptedness is the state of being adapted: the degree to which an organism is able to live and reproduce in a given set of habitats.
On the western peninsula, the changing climate means different weather is turning sheets of snow and ice into a land of rain and mud. Older penguins are equipped with waterproof layers of feathers allowing them to move swiftly in the water, and also allowing them to stay warm on land.

Carrying capacity can be defined as a species' average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.
6.Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.
