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.

Answers
Answer:
a) temperature
Explanation:
took test and got right
light intensity does not affect the rate of photosynthesis .
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.

Answers
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.

Which of the following would be affected when a protein is denatured?
a.) amino groups
b.) primary structure
c.) side chains
d.) tertiary structure
Answers
"b" why because primary structure needs protein and if protein denatured,primary structure will affected instantly!
#followandheartallmyquestion
When a protein is denatured by chemical, heat or other substances, the primary structure remains intact. Hence, the correct answer would be the tertiary structure.
Denaturation of proteins generally causes the breakage of weak bonds on which the folding and the entire protein structure is built. When this happens:
the peptide bonds between the component amino acids remain intact. Hence, the primary structure is conservedthe destruction of other bonds means that the secondary and tertiary structures are affected.Agents that are capable of denaturing proteins include high temperature, changes in acidity/basicity, UV radiation, high concentration of salts, and so on.
The correct answer as to which would be affected when a protein is denatured in this case would, therefore, be the tertiary structure.

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).

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