In many tropical rainforests, people clear land by cutting down trees and burning them. After a few years, the soil runs out of nutrients and cannot be farmed any longer. How does this affect Earth's atmosphere?
Answer:
Land will convert into desert eventually
Explanation:
When the soil gets devoid of nutrient, it will be unable to support trees, plants or vegetation of any type. Trees and plants are responsible for holding the soil tightly and prevent it from eroding.
Once there will be no nutrient in soil, there will be no trees, plants or vegetation and hence there will be no mechanism to prevent soil erosion. Thus, the soil will erode due to deforestation and the land will convert into desert eventually

Explanation:
What might occur if the stoma were all located on the top of the leaves?
Answer:
It depends on the plant and its environment. In a mesic terrestrial environment, the plant wouldn’t be optimized. Natural selection would then come into play and there would be an evolutionary trend towards stomata located on the lower leaf surface.
In the case of water lily, the lower epidermis is in contact of the water, and stomata are restricted to the upper surface of the leaf. This is an optimal solution for the plant. Natural selection will work to conserve that arrangement. In this case, stomata on the lower surface would exist at a water-air interface, and the diffusion of gasses across that interface would be glacially slow. Further, the stomata on the lower surface would present an opening where pathogens can enter the leaf.

A friend of mine came to see me one day and told me a story of how he met his identical twin that he never knew about. When I questioned him about the details, I got some information about the two men.
John Smith (my friend)
DOB: 11/12/77
Height: 6’1
Eyes: Brown
Hair: Brown
Dave Jones (suspected twin)
DOB: 11/11/77
Height: 6’1
Eyes: Brown

What should I tell him about his twin?
In a certain ecosystem, there is a population of lynx that feed on snowshoe hares. If there is less food for the hare for several years, what will most likely be the result for the lynx population?
A. The lynx population will increase.
B. The lynx population will decrease.
C. The lynx population will go extinct.
D. The lynx population will stay the same.
Answer:
B
Explanation:
since the will be less food for the hare, less hare will be able to survive. that means some lynx will not get hare and the lynx will die which means the lynx population will decrease

Explanation:
It is flu season! The flu is caused by a virus. Scientists continue to debate whether or not viruses are alive. If we consider the image of the flu virus seen here, we could say that a virus is NOT alive because https://www.usatestprep.com/modules/gallery/file.php?id=1531 for the picture
Answer: the answer is D
Explanation:
Answer: There is no cellular structure
Explanation: If we use the image to support our argument, we could say a virus s not living because there is no cellular structure. All prokaryotic cells lack a nucleus. We cannot tell, from the image, anything about its way of life.

What do the NADPH and ATP do in the Calvin cycle?
Answer:
ATP and NADPH produced by the light reactions are used in the Calvin cycle to reduce carbon dioxide to sugar. ATP is the energy source, while NADPH is the reducing agent that adds high-energy electrons to form sugar.

Two interacting systems involved in plant transport are shown here. Which statement best describes the function of xylem and phloem in transporting substances throughout the plant?
Answer:
C. Xylem transport water and nutrients from the soil to the leaves while phloem transport carbohydrates from the leaves to the rest of the plant.
Explanation:
In corgis, a breed of dog, short tails are completely dominant to long tails. If two long-tailed corgis have puppies, what is the percent chance of having a puppy with a short tail?
Answer:
0%
Explanation:
This question involves a single gene coding for tail length in a breed of dog called Corgis. The allele for short tail (S) is dominant over the allele for long tail (s).
According to this question, two long-tailed corgis are crossed i.e. ss × ss. Each parent corgis will produce only 's' gametes. Using this gametes in a punnet square (see attached image), the following proportion of puppies will be produced:
All ss (long-tailed) offsprings/puppies.
Based on the question asked, 0% or none of the puppies produced will have a short tail.
Write a paragraph explaining the steps involved in a muscle contraction starting from the brain sending a signal to the muscle and ending with the muscle contraction.
Answer:
A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles.Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron. The neuromuscular junction is the name of the place where the motor neuron reaches a muscle cell. Skeletal muscle tissue is composed of cells called muscle fibers. When the nervous system signal reaches the neuromuscular junction a chemical message is released by the motor neuron. The chemical message, a neurotransmitter called acetylcholine, binds to receptors on the outside of the muscle fiber. That starts a chemical reaction within the muscle.Acetylcholine Is Released and Binds to Receptors on the Muscle Membrane.
A multistep molecular process within the muscle fiber begins when acetylcholine binds to receptors on the muscle fiber membrane. The proteins inside muscle fibers are organized into long chains that can interact with each other, reorganizing to shorten and relax. When acetylcholine reaches receptors on the membranes of muscle fibers, membrane channels open and the process that contracts a relaxed muscle fibers begins:
Open channels allow an influx of sodium ions into the cytoplasm of the muscle fiber.
The sodium influx also sends a message within the muscle fiber to trigger the release of stored calcium ions.
The calcium ions diffuse into the muscle fiber.
The relationship between the chains of proteins within the muscle cells changes, leading to the contraction.
