Answers

Answer 1

Answer:

Due to stomata.

Explanation:

Transpiration occurs mainly through leaves because of the presence of stomata n the lower side of the leaves. Transpiration refers to the loss of water from the body of plants so leaves has small pores which is used by the plant to regulate internal temperature.  Sunken stomata lower the rate of transpiration because it is not directly exposed to the surface which protects the escaping water vapor due to air.

How does cooling of magma affect crystal size?

A) Slow cooling creates small crystals

B) Fast cooling creates both large and small crystals.

C) Slow cooling creates large crystals

D) Fast cooling create large crystals

Answers

Answer:

When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

Answer:

I learned about this, Uhm...

C is the right answer bc igneous rocks cool and form crystals.

Lava, since it comes out of a volcano, cools faster and has smaller crystals since they could not be developed enough.

Magma, still underground, cools slower than lava because of all the density and heat, which causes bigger crystals.

Hope this helps :)

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.

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).

Macromolecules are polymers containing long chains of molecular sub-units known as monomers. These play an important role in biophysical processes and composed of thousands of atoms that are covalently bonded.

Carbohydrate is a biomolecule having carbon, hydrogen and oxygen atom.It is the main source of energy of the body.

Lipids are macromolecules that are insoluble in water and the main function is to serve as structural component of cell membrane.

Proteins are macromolecules that are extremely complex in structure and made up of amino acid residues joined by peptide bonds.

Nucleic acids are biopolymer macromolecules and composed of nucleotide. The function is to carry genetic information which helps to make RNA.

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.
