other molecules, and helps regulate certain reactions in the human body?
A. carbohydrates
B.lipids
C. proteins
D. nucleic acids

Answers

Answer:

C : Proteins

Explanation:

(Can I get brainlest?)

Proteins are the molecules that provide building blocks for tissues, transports other molecules, and helps regulate certain reactions in the human body. The correct option is C.

What are proteins?

A protein is a found naturally, extremely complex substance composed of amino acid residues linked together by peptide bonds.

Proteins are found in all living life forms and contain a variety of important biological compounds such as enzymes, hormones, and antibodies.

Proteins are massive complex molecules that perform numerous important functions in the body.

They are essential for the structure, function, and regulation of the body's tissues and organs and do the majority of the work in cells.

Proteins are molecules that serve as foundation for tissues, transport other molecules, and aid in the regulation of certain bodily reactions.

Thus, the correct option is C.

#SPJ2

The average molecular weight of proteins encoded in the human genome is about 50,000. A few proteins are very much larger than this average. For example, the protein called titin, which is made by muscle cells, has a molecular weight of 3,000,000. Estimate how long it will take a muscle cell to translate an mRNA coding for an average protein and one coding for titin. The average molecular mass of amino acids is about 110 daltons. Assume that the translation rate is two amino acids per second.

Answers

Answer:

13,636 seconds = 227.3 minutes = 3.79 hours

Explanation:

The titin protein has a molecular weight of 3,000,000 daltons, while the average molecular mass of one amino acid is 110 daltons, so it is expected that this protein is composed of 27,273 amino acids (3,000,000 daltons/110 daltons = 27,272.72). Moreover, and since the translation rate is two amino acids per sec, it is expected that the protein will be synthesized in approximately 3.79 hours (27,272.72/2 = 13,636 seconds = 227.3 minutes = 3.79 hours).

Explain why the cell membrane is the brain of the cell, as opposed to the nucleus.

Answers

Answer:

because it holds the information needed to conduct most of the cell's functions.

Cell membrane controls the transport of molecules across the cell and its external environment, Thus, it is called as the brain of the cell.

Why is cell membrane important?

Cell membrane regulates most of the cellular activities through the property of selective permeability.

It is responsible for maintaining the cellular equilibrium through influx and efflux of ions and molecules.

There are various receptors present on the cell membrane which regulates the vital biochemical processes taking place in the body.

Cell membrane functions in the cell-cell recognition and cell signalling through various receptors.

Cell membrane is important in regulating body homeostasis. It offers the protective environment to the cell.

Control and regulation of activities is processed through brain.

Therefore, cell membrane is considered as the brain of the cell.

state two features of diffusion that do no apply to active transport​

Answers

diffusion moves ions from high concentration to low using no metabolic energy and active transport uses metabolic energy in the form of atp to move ions from high concentration to low concentration

What does active transport require that diffusion does not? Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

What two features distinguish active transport from diffusion? An example of diffusion is oxygen moving from the airways to the lungs - there is very little oxygen in the lungs but lots in the air. Active transport is the movement of particles from an area of low concentration to an area of high concentration. This process requires energy (ATP)

What are the 2 key features of active transport? There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient. An example of active transport in human physiology is the uptake of glucose in the intestines.
Both use ion channels to move ions across the cell membrane, in or out of the cell. Differences: Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.

O A. the body's nitrogen levels
B. the body's internal environment
OCthe body's external skin and hair
0
D. the body's support for movement

Answers

Answer:

B. the body's internal environment

Explanation:

Homeostasis is defined as the process of maintaining the internal environment of the body.

All the systems work together to maintain homeostasis. The nervous and endocrine systems are two important system that helps in maintaining homeostasis.

The nervous and endocrine systems are linked with hypothalamus that controls the internal environment of the body by releasing and inhibiting hormones. These hormones keep pH,  temperature,  and other internal conditions stable that support homeostasis.

Hence, the correct answer is "B. the body's internal environment".

what is photosynthesis ?

The process in which plants, algae and certain bacteria use light energy of sunlight, water, carbon dioxide and convert light them into chemical energy and starch. called as photosynthesis.

Photosynthesis occur in special organelles named chloroplast which has its own DNA, genes and hence can synthesize their own proteins.

Chloroplasts have stroma, fluid, and stack of thylakoids known as grana, three types of chlorophyll such as chlorophyll a, chlorophyll b, and carotenoids.

Oxygenic photosynthesis is  commonly observed in plants, algae and cyanobacteria where electrons are transferred from water to carbon dioxide by using light energy, to produce energy,  oxygen is produced along with carbohydrates.

C. Phyletic gradualism states that speciation occurs constantly over time, and punctuated equilibrium states that many species evolve rapidly at specific points in time
D. Phyletic gradualism is supported by the fossil record, but punctuated equilibrium isn't

Answers

A is the correct answer

A. Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is

Punctuated equilibrium and phyletic gradualism are two opposing evolutionary tendencies that can be seen in the geological record. Species in punctuated equilibrium tend to demonstrate morphological stasis between rapid speciation episodes, whereas species in phyletic gradualism change more frequently. "Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is," says the statement that best summarizes the ideas of phyletic gradualism and punctuated equilibrium.
