Im studying human scalp does anyone know what this is?
The picture represents the atypical mole or also known as dysplastic nevi. Such types of moles are looking unusual and have irregular features under the microscope.
What is a Human scalp?A human scalp may be defined as the fraction of the envelope of the human head usually covered with hair in both sexes. It is the region that is composed of soft tissue layers that cover the cranium.
The dysplastic nevi are although benign in nature but significantly have a potent threat to melanoma which is a dangerous form of skin cancer.
Such types of moles are painful, itching, crusting, and swelling with the duration of time. They are required to be checked immediately by a trusted dermatologist.
Therefore, the picture represents the atypical mole or also known as dysplastic nevi.

If a people consume more protein than their body needs, the excess protein is __________. excreted in their urine deaminated and used/stored as glucose or fat stored in their muscles excreted in their feces
When you consume more protein than your body needs, the excess protein is used to provide your body with energy or turned into fat.
How is protein essential for the body?The protein need for the body depends on the age, physical activities, development and changes. For all these processes, body need a large amount of protein. Our body is at the phase of breaking and building muscles, so high amount of protein is not harmful. Excess amount of protein is stored in the body in form of fats and break down when need for body energy requirements. So if the amount is increase it will result in weight gain and body size.
Even a high amount of proteins is healthy and safe, but massive increase in amount can cause harm to the body.
Thus,harmful effects of massive amount of protein depend on patient health.

Cell theory will not ever become the law of cells because cells undergo changes as mutations occur within them, and developing anything beyond cell theory would be impractical.
What do you mean by Cell theory?Cell theory may be defined as a theory given by M.J. Schleiden and T Schwann which states that all living organisms are made up of cells which are the smallest unit of all living entities.
It is only due to mutations, cell changes its identity and properties randomly. Hence, it seems very tough for scientists to analyze all the mutations in the cell.
Therefore, cell theory will not ever become the law of cells because cells undergo changes as mutations occur within them, and developing anything beyond cell theory would be impractical.

what is the overall reaction ( equation ) for photosynthesis?
Answer:
6CO2 + 6H2O → C6H12O6 + 6O2
Explanation:
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

Cyanobacteria are photosynthetic marine organisms. why would these organisms likely be found only in shallow ocean zones? the current in deeper ocean zones is too traumatic. the amount of oxygen in deeper ocean zones is too high. the amount of light in deeper ocean zones is too dim. the amount of pressure in deeper ocean zones is too low.
Cyanobacteria as photosynthetic organisms would likely be found only in shallow ocean zones because the amount of light in deeper ocean zones is too dim.
What are cyanobacteria?Cyanobacteria are any of the very many photosynthetic prokaryotic microorganisms, of phylum Cyanobacteria, once known as blue-green algae.
Cyanobacteria are photosynthetic organisms, hence, require sunlight energy to undergo the process.
Light from the sun can only reach the photic zone of a water body, hence, cyanobacteria as photosynthetic organisms would likely be found only in shallow ocean zones because the amount of light in deeper ocean zones is too dim.

Answer:
The amount of light in deeper ocean zones is too dim.
Explanation:
Not: the amount of oxygen in deeper ocean zones is too high, because their is barely any oxygen in deep ocean. Not:
The current in deeper ocean zones is too traumatic, it is very still, no currents.
The amount of pressure in deeper ocean zones is too low, there is high pressure deep ocean, like for example, when you go deeper in water your ears get filled, like you can't hear because of the high pressure.
So the answer is; The amount of light in deeper ocean zones is too dim.
