Explanation:
The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. ... A mate must be found, the egg must be fertilised by sperm, and then the offspring develop.
Answer:
because it increases the gene pool
Explanation:
So sexual reproduction requires two organisms, a male and a female, and their offspring has a combination of both of the parents, this varies the gene pool. Then the offspring creates more offspring, further varying the gene pool.

________ thousands of tiny projections that add even more surface area to villi
Answer:
Each villus, in turn, has thousands of even smaller projections called microvilli (singular: microvillus).
Explanation:
The villi contain capillaries, which are tiny blood vessels. Nutrients are absorbed into these capillaries across the surfaces of the villi and microvilli. Because there are millions of these tiny projections, they greatly increase the surface area for absorption.
The thin segment of the nephron loop's descending limb ________. The thin segment of the nephron loop's descending limb ________. is easily broken and replaced often aids in the passive movement of water out of the tubule aids in the passive excretion of nitrogenous waste helps to pack a greater number of nephron loops into a smaller space
Answer:
The correct answer is ''aids in the passive movement of water out of the tubule''
Explanation:
The nephron loop has a descending branch, which goes to the renal medulla, and an ascending branch, which goes back to the cortex. The nephrons of these kidneys can have loops of Henle of different dimensions. The thin segment of the loop has thin epithelial membranes, its cells are highly permeable to water, but not to solutes. The water that exits from the descending portion of the nephron loop into the medullary space is immediately reabsorbed by the peritubular capillaries, causing osmolality to increase in both the tubular fluid and the medullary interstitial fluid. The characteristics of the descending branch differ from one species to another, the normal thing is that in one way or another, the osmotic concentration of the urine that moves through it is balanced with that of the interstitial fluid.

Do you think the offspring produced by the two processes are genetically identical to organism 1? Explain your reasoning.
Answer:
Process 1 involves one parent, organism 1. So, the offspring produced through process 1 will be genetically identical to organism 1. Process 2 involves organism 1 and organism 2, so the offspring will have genes from both of them. These offspring will be genetically different from organism 1.
Explanation:
Trust me, this is the exact answer.
Question 4
In this Food Web Pyramid Which type of consumer gets only 10% of the energy stored in plants?
A. Herbivore
B. Carnivore
C. Omnivore
D. Secondary Consume
Answer:
Herbivore, of course, I'm really sure that we all know exactly what a herbivore is, but as a refresher, a herbivore is like a vegetarian, they have a diet strictly based on plants. Carnivore's eat meat, not vegies, and an omnivore eats both, most humans are labeled as omnivores, except vegetarians. So your answer is Secondary Consume. This is because they only receive 10% in vegies, Primary Consume get 90%, Herbivores are Primary Consume's.

a student wants to hold the sides of a garbage bag to the sides of her trash can she tries round rectangular and square shaped magnets but the magnets do not stick to the sides of the trash can, what is a reason the magnets do not stick to the sides of the trash can ?
Answer:
If the insulating material covered around the can.
Explanation:
If the can is covered with thick layer of insulating material then it can't be attracted by the magnet because there is a gap between magnet and metal. Can is a metal which is attracted by the magnets just like iron and copper etc. If there is no insulating material between magnet and can, then it must be attracted by the magnet so that's why we can say that insulating material is responsible for the no attachment of magnet to the can.

Hybrid cars can switch back and forth between gasoline power and electric power in a way that reduces fuel use
As a result, they are more fuel efficient than traditional cars that run only on gasoline. They offer one solution to
the problem of people consuming too many fossil fuels to meet their transportation needs.
Which of the following behaviors could further refine this solution?
A. People can drive hybrid cars instead of using more conservative tecnics.
B. People can drive separate hybrid cars instead of carpooling
C. People can use additional conservation tactics, like sometimes bicycling
D. People can drive hybrid cars more often than they need to
Answer:
C. People can use additional conservation tactics, like sometimes bicycling
Explanation:
According to this question, cars called HYBRID cars are said to have the ability to switch back and forth between gasoline power and electric power in a way that reduces fuel use. This solves the problem of buying excessive transport fuel.
Asides the hybrid car, one can also use a more conservative approach, which is bicycling. Hence, the use of additional conservation tactics, like sometimes bicycling.
