The majority of electrons in an active mitochondrion travel through which pathway: citric acid cycle, Nadph, aerobic respiration, and oxygen.
Unattached or attached to an atom, an electron is a negatively charged elementary particle (not bound). One of the three main types of atoms inside an atom, along with protons and neutrons, is indeed an electron that is linked to the atom. An atom's nucleus is made up of electrons, protons, and neutrons. The exterior of the nucleus is surrounded by negatively charged electrons in orbit. It can be challenging for scientists to monitor them since they rotate so quickly. They are the littlest particles in a particle and can fit 1 million of them into a central particle. People are drawn to the protons' positive charge.

Select the statement that describes the major site where antiviral action is blocked by the protease inhibitors. Select one: a. The protease inhibitors block the ability of the human immunodeficiency virus from attaching and entering the cell membrane. b. The protease inhibitors block the uncoating process of the human immunodeficiency virus by binding to protease. c. The protease inhibitors block the nucleic acid synthesis of the human immunodeficiency virus. d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.
Answer:
d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.
Explanation:
Protease inhibitors are antiviral agents used to fight against pathogenic viruses such as retroviruses (e.g., human immunodeficiency virus, HIV) and RNA viruses (e.g., hepatitis C virus). Protease inhibitors can drastically reduce the viral load. Protease inhibitors may target 1-virus-encoded proteases which are responsible to produce functional proteins from polyprotein precursors and 2-processing structural proteins that are required for virus assembly. Some examples of protease inhibitors include, among others, ritonavir and indinavir, which are used in patients with HIV infection.

The word “contract” in this paragraph tell you:
A. The muscles are involuntary
B. The muscles are aching
C. The muscles become larger
D. The muscle tighten inward
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.

A student created a table to compare animal adaptations. Based on the table, which
animal has a behavioral adaptation, and how does it give the animal an advantage?
Animal Adaptation
Duck Webbed feet
Squirrel Collects and stores food
The duck, because the behavioral adaptation allows it to catch prey.
The duck, because the behavioral adaptation helps it survive the environment.
The squirrel, because the behavioral adaptation provides food during winter.
The squirrel, because the behavioral adaptation to have more offspring.
Answer:
B
Explanation:
Ducks have the webbed feet so, they could swim in the water so they don't drown. That is animal adaptation to the environment.
Based on the given table, the animal with a behavioral adaptation is the squirrel, which collects and stores food. This adaptation gives the squirrel an advantage by helping it survive during times when food is scarce, such as during the winter months, which is in the third option.
What is behavioral adaptation?The behavioral adaptation of collecting and storing food is an important survival strategy for many animals, including squirrels. During times of abundance, such as the fall months, squirrels will collect and store food, such as nuts and seeds, in order to have a food source during times of scarcity, such as the winter months. This allows the squirrel to survive and avoid starvation during times when food is less readily available.
Hence, Based on the given table, the animal with a behavioral adaptation is the squirrel, which collects and stores food. This adaptation gives the squirrel an advantage by helping it survive during times when food is scarce, such as during the winter months, which is in the third option.

How would life on earth change if there was no clean water or air?
Answer:
With no water supply, all vegetation would soon die out and the world would resemble a brownish dot, rather than a green and blue one. Clouds would cease to formulate and precipitation would stop as a necessary consequence, meaning that the weather would be dictated almost entirely by wind patterns.
are food will die then the animals will die then we would die and the earth wouldn't be green no more it will be brown and bry there will be no clouds ether or grass

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.
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.

What is the molecule called that all living things use for immediate
useable energy?
ATP, Sugar,fat, All of these
Hello there!
I think ATP would be the answer in this instance. See, ATP is the pure form of energy that cells prefer to use. Sugars and fats are good for energy, too - but sugars and fats must be converted into energy before use. So ATP is the only energy source listed that doesn't need to be metabolized before the cell can use the energy.

Explain how the nervous and endocrine systems work together to control the body and maintain homeostasis in a paragraph.
Answer:
Explanation:
The nervous system controls virtually all body activities, and the endocrine system secretes hormones that regulate these activities. Functioning together, the organ systems supply body cells with all the substances they need and eliminate their wastes. The glands of the endocrine system secrete hormones into the bloodstream to maintain homeostasis and regulate metabolism. The hypothalamus and the pituitary gland are the command and control centers, directing hormones to other glands and throughout the body.
