i need help with this can someone help me?
Explanation:
Predation plays an important role in the overall health of an ecosystem since it regulates the population of preys as well as maintain the population of higher-level consumers. If predators were eliminated from an ecosystem, it would cause an increase of the population of preys and potentially decrease the population of other organisms on lower trophic levels. An example of such effect can be seen from the population of rabbits and plants supposing that foxes, eagles and snakes are eliminated from the ecosystem. The rabbit population will multiply, causing a decrease in the population of plants such as grass that rabbits feed on.
Hope this helps :)

What is the most distal interphalangeal joint?
How many carpal bones are in the wrist?
Answer:
"proximal interphalangeal joints" (PIJ or PIP), those between the first (also called proximal) and second (intermediate) phalanges.
"distal interphalangeal joints" (DIJ or DIP), those between the second (intermediate) and third (distal) phalanges.
our wrist is made up of eight small bones (carpal bones) plus two long bones in your forearm — the radius and the ulna. The most commonly injured carpal bone is the scaphoid bone, located near the base of your thumb.
Explanation:

Answer:
True
Explanation:
Answer:
true
Explanation:
According to CDC, between 1998 and 2011, about 79% of the dairy-related illness outbreaks were caused by
cheese or raw milk (unpasteurized) products. 148 outbreaks and 2,384 illnesses were reported during that time.
284 required hospitalizations and 2 deaths were caused by cheese or raw milk products. Although these numbers
seem small, there are risks. At a federal level, although the FDA forbids the sale or distribution of raw
(unpasteurized) milk, 13 states allow the sale of raw milk in their retail stores, and another 17 states allow the
sale of raw milk on the actual farm that the milk was produced.
Explain the thinking that caused the FDA to forbid the sale and distribution of raw milk.
A)
Unpasteurized milk has the shortest shelf-life.
B)
Parasitic organisms that live in cows can be passed on to humans.
Unpasteurized milk has a short shelf-life and costs more money to produce.
D)
Microorganisms found in unpasteurized milk can cause illness and even
death.
Answer: D
Explanation:
D relates to the answer, it is saying that a lot of bacteria and viruses can be on unpasteurized milk, this can really make the milk bad and you can get seriously ill or even die from this.

5.21 Unit Test: Water and Oceans - Part 1
What forms as a result of the wind's frictional force on water?
O deep sea currents that move in a path opposite to the wind currents
O surface currents that move in a path opposite to the wind currents
surface currents that move in a path similar to the wind currents
deep sea currents that move in a path similar to the wind current
Answer:
Surface currents that move in a path similar to the wind currents
Explanation:
One of the reasons of the movement of the surface of the oceans is the force of the blowing wind. When there is a movement of wind over the surface of the ocean, the surface friction is created. Because of this there is an energy transfer between the force of the wind and the surface of the ocean water. This results in the creation of roughness of the surface of the ocean. The more the surface area of the ocean, the more is the transfer of the energy.
How does the molecule marked A enter our body
Answer:
Explanation:
A, breathing. It contains oxygen and that is what we use to breath.
Answer:
eating.
Explanation:
glucose (C6H12O6) is a monosaccharide aka a carbohydrate that we eat.
The mitochondria is known as the “powerhouse of the cell." Why?*
glucose is broken down into cellular energy (ATP).
lipids release energy as they form polypeptide bonds.
glucose is created through the process of photosynthesis.
proteins create energy as they are converted from sugars.
Answer:
The correct answer is - glucose is broken down into cellular energy (ATP).
Explanation:
Mitochondria is the double membrane cell organelle presents in all eukaryotic cells that produce the energy by the process of cellular respiration from the food to the cell to perform its day to day functions.
The cellular respiration is the process that involves the braking of the sugars into simple molecules and these catabolic reaction produce energy with CO2 and water as waste. The energy is stored in the form of ATP which is generated in the inner membrane of mitochondria. ATP is used by the cell to perform its function.
Thus, the prower house of the cell is mitochondria.

What are negative impact of genetic testing in humans?The following are some drawbacks or hazards of genetic testing: Your stress and anxiety may increase throughout testing.
Results in some circumstances could be ambiguous or inconclusive. Detrimental effect on connections with family and friends.
Because the findings of genetic testing can expose information about family members besides the test subject, this causes conflict between families.
Another issue is the potential for genetic discrimination in insurance or the workplace.
Therefore, Genetic testing could cause discrimination by revealing health risks.
