Answer: The options are not given, here are the options.
a. located in the space outside the nucleus.
b. spread evenly throughout an atom. c. concentrated at multiple sites in an atom.
d. concentrated in the center of an atom.
The correct option is D.
concentrated in the center of an atom.
Explanation:
In an atomic model, the atomic particles has the nucleus which is located at the center of the particle. This nucleus contain positive charge which is called proton at the center and the neutrons(no charge). The electrons is located out side the particle she'll or nucleus and atomic particles become neutral because the number of protons is equal to the number of electrons which is negatively charge orbiting outside the nucleus.

Fatigue? (Hint: consider how the reactants of aerobic respiration get to your musde cells)
Answer: Heart strength and healthy circulatory system
Explanation:
Fatigue is considered to be the state in which a person cannot maintain the level of performance or training expected. Muscles are able to obtain energy by aerobic or anaerobic respiration and both use carbohydrates or sugars, but only aerobics needs oxygen. To perform physical activity, the heart pumps more oxygen to the muscles that are performing the exercise. When the muscles work harder, the body consumes more oxygen and produces more carbon dioxide. So, aerobic respiration is a type of metabolism in which the organism uses energy from organic molecules, especially as glucose, where the carbon is oxidized by the oxygen. 36 molecules of ATP per glucose are produced during aerobic respiration.
During an effort, the energy produced by aerobic breathing is not enough and muscles need to produce a complementary energy through anaerobic respiration which provides less energy than aerobic respiration. This type of cellular respiration produces waste products that the cells must eliminate, for example lactic acid, which remains in the muscles producing pain after exercise. Only 2 molecules of ATP are produced for each glucose during anaerobic respiration.
Therefore, the heart strength is important because that organ is responsible for carrying oxygen to the muscles, which is needed to perform cellular respiration and get more energy to perform the exercise. And there must be also a healthy circulatory system that delivers that oxygen to every part of the body.
What are Metabolic Reactions?
Metabolism refers to all of the chemical reactions that take place inside living cells. Unicellular and multicellular organisms must control their metabolism in order to survive.
Give an example of a prokaryotic cell?
Answer:
blue-green algae
Explanation:
Answer:
Bacteria is the biggest example but these are also examples blue-green algae, E. coli, and mycoplasma.
Explanation:
This is what it is: Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.

how does tempature impact air movement?
Answer:
The heating of the earth, which in turn heats the atmosphere, is responsible for the motions and movements of the air in the atmosphere. The faster molecules move, the hotter the air. As the molecules heat and move faster, they are moving apart.
Explanation:
Answer:
As you move higher off the ground, it gets colder *and vice versa*.
Explanation:
When we move off the ground, density is pulled down to the ground due to gravity. Therefore, it gets colder. It's also because of our atmosphere. (Vice versa, of course)
P.S. Density and gravity are also key parts of climate change, keep that in mind.
Are eukaryotes multicellular or unicellular or both?
A. The deer population exceeded the carrying capacity, providing predators with a surplus of food. As the deer population
decreased, so did the carrying capacity.
B. The deer population increased as the carrying capacity stabilized. As the carrying capacity decreased, the deer population
decreased.
C. The deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there
was less food available, reducing the carrying capacity.
D. As the deer population reached a maximum so did the carrying capacity. As the deer population decreased, so did the
carrying capacity until the environment stabilized and the deer population could increase again.
Answer:
C seems to be the most reasonable answer.
Explanation:
The graph depicts that in an ecosystem the deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there was less food available, reducing the carrying capacity.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Review why carbon can form a variety of organic compounds in a variety of shapes.
Answer:
Carbon atoms readily bond with each other and can form long chains, branched molecules, and rings—an enormous variety of carbon backbones for organic molecules.
Explanation:
Carbon atoms easily connect with one another, allowing for the formation of lengthy chains, branching molecules, and rings—a vast array of carbon backbones for organic molecules.
What is carbon?Carbon is defined as the elements are distinguished by their capacity to form firmly bound chains that are sealed off by hydrogen atoms.
Carbon is also defined as an atomic number 6 chemical element with the symbol C.
Carbon is nonmetallic and tetravalent, with each atom releasing four electrons to form covalent chemical connections.
Carbon has the capacity to quickly form bonds with other atoms, which allows for greater flexibility in the shape and function of biomolecules such as DNA and RNA, which are required for the defining traits of life growth and replication.
An organic molecule is defined as a complex molecule composed mostly of carbon atoms that are bound with other elements and/or other carbon atoms.
Carbohydrate, lipids, nucleic acid and protein are some of the example of organic molecules.
Thus, carbon atoms easily connect with one another, allowing for the formation of lengthy chains, branching molecules, and rings—a vast array of carbon backbones for organic molecules.

What is the elephant getting when the bond is broken in sucrose?
Answer:
Energy
Explanation:
The elephant is getting energy when the bond is broken into sucrose because as sucrose is broken down, it is hydrolized by enzymes sucrase which break the glycosidic bond and convert it to glucose and fructose in the upper gastrointestinal tracts. Glucose and fructose are then absorbed into the blood stream which glucose serve as energy source or stored as glycogen in the gastrointestinal tracts.
