Answer:NH2 side group and COOH side group.

Explanation:

Proteins can buffer a drop in pH by their NH2 side groups and can buffer an increase in pH by their COOH side groups.

Large, intricate molecules known as proteins play a variety of vital functions in the body. They are crucial for the structure, operation, and control of the body's tissues and organs and carry out the majority of their job inside cells.

Many thousands of amino acids, which are smaller building blocks of proteins, are linked together in lengthy chains to form proteins. To create a protein, 20 distinct kinds of amino acids can be mixed. Each protein's precise function and distinctive 3-dimensional structure are determined by the order of the amino acids.

Combinations of three DNA building units (nucleotides), which are dictated by the order of genes, are used to code for amino acids.

Therefore, Proteins can buffer a drop in pH by their NH2 side groups and can buffer an increase in pH by their COOH side groups.

The formation of one isochromosome

Explanation:

In cytogenetics, an isochromosome is a structurally abnormal chromosome that renders two chromosome arms which are identical inverses of each other. An isochromosome is caused by simultaneous duplication and deletion of genetic information during DNA replication. The resulting isochromosome will contain two identical copies of either the long or short chromosome arms that are disposed as a mirror image.

The provided question is incomplete as it lack the group of choice required to answer, however, the correct options are as follows:

A) increased extracellular fluid water levels

B) decreased filtrate NaCl concentration

C) sympathetic stimulation

D) decreased stretch due to decreased blood pressure

Answer:

The correct answer is option A) increased extracellular fluid water levels

Explanation:

Juxtaglomerular granular cells are the group of cells present in the kidney that produce, store and release the enzyme known as the renin. These cells are present in the walls of the afferent arterioles mainly.

Renin is the enzyme release in order to release angiotensin I in order to increase the blood pressure. The release of the renin is depend on various triggers sense by juxtaglomerular granular cells such as decreased filtrate NaCl concentration , decreased stretch due to decreased blood pressure and sympathetic stimulation  or other stimuli. However, increased extracellular fluid water levels is not responsible for the release of renin.

Answer:

Increased  evaporation and transpiration  dries out the ground  leaving  less water to move to the atmosphere fewer clouds and less  precipitation, which can lead to drought conditions.

In some areas evaporation and transpiration from plants can be so high that the amount of water available to move to the atmosphere is significantly reduced. This is usually the case in areas that are lacking in open water resources.

As there is less water moving to the atmosphere, there will be less water condensing into clouds and thus less rain. If this persists, it can lead to a drought.

The option that best describes something that occurs during translation is an mRNA template being used to create an amino acid chain.

Translation, also known as protein synthesis, is one of the steps in gene expression. It involves the translation of genetic codes in an mRNA molecule to their respective amino acids in the ribosome.

The first step in gene expression is the transcription of genetic information on DNA into codes in the form of an mRNA. The mRNA then undergoes some processing before the genetic codes are translated, with the help of the tRNA which carries the anticodons, in the ribosome.

The codes are not just translated to their respective amino acids but the latter are joined together by peptide bonds to form the primary structure of proteins.

Answer:

NADP is the cofactors in photosynthesis which loses electrons,becomes reduced(NADPH) in photosynthesis. It transfer  electrons  in reduced form(NADPH) into the stroma of the chloroplast. The H is splits into e- and H+

These electrons for the ETC chains, generates the PMF for pumping H+ as protrons into the thylakoid  intramembranes.

Outer membrane covers  the intramembrane space, between these two membranes layers. The protons in the intramembrane space generate the electrochemical gradient for the supply of  the energy used by ATPase synthase for ATP synthesis from phosphorylation with ADP.

The chloroplast is made up of both the outer and inner membrane,separated by the intramembrane space. The walls of the intramembrane space is guided by the outer envelope. 

Therefore with the outer envelope removed, the intramembrane is exposed,more protons(H+) are released, but can not be held in the outer envelope to form electrochemical gradients,beacause the intramembrane space is now permable.

Thus   the rate of reduction of DCPIP is faster.The  color changes to colorless increases when reduced , from blue color.

Explanation:

The reduction of the dye DCPIP (2,6-dichlorophenolindophenol) works best using chloroplasts whose outer envelopes have been damaged during preparation because it allows easier access for DCPIP to the electron transport chain (ETC) components.

The outer envelope of chloroplasts contains phospholipid bilayers that act as barriers, limiting the movement of molecules in and out of the chloroplasts.

When the outer envelopes are damaged, DCPIP can diffuse more freely into the chloroplasts and come into contact with the ETC components, particularly photosystem I.

DCPIP acts as an electron acceptor, and in the presence of light, it is reduced by electrons from photosystem I, resulting in its color change from blue to colorless.

The damaged outer envelopes facilitate the interaction between DCPIP and the ETC, leading to more efficient reduction.

Answer:

A 550

Explanation:

0.55 hectometers is equivalent to 550 decimeters.

Since 0.01 hectometers and 10 decimeters (1 meters) are both equal to one meter, :550 decimeters (55 meters)  are equal to 0.55 hectometers. Thus, option A is correct.

What are hectometers and decimeters?

The International System of Units (SI) defines the hectometer (International spelling as used by the International Bureau of Weights and Measures; SI symbol: hm) or hectometer (American spelling) as a unit of length that is equal to 100 meters and one tenth of a kilometer.

The ruler, which is 12 inches (0.3 m) (in) or 30 centimeters (cm) long and equals one foot or slightly under one-third of a meter, is visible. 100 meters make up a hectometer.

To produce one hectometer or 328 feet (99.97 meters), that would need about 328 rulers. That is a lot of rulers, I must say. Here is a simpler method for recalling a hectometer's length.

Decimeter measurements are uncommon in everyday life. It is simpler to use 0.1 m or 0.5 m when the length is less than a meter because one meter is not a particularly  length.

Therefore, 550 decimeters (55 meters)  are equal to 0.55 hectometers.
