A)Photosynthesis

Explanation:

  • Photosynthesis is the process by which green plant prepare glucose using carbon dioxide and water in presence of sunlight and chlorophyll.
  • The openings on the undersurface of the leaves are called stomata.
  • Stomata play a vital role in exchange of gases between tissues and the surrounding.
  • If these openings remain closed then carbon dioxide will not diffuse into the cells and oxygen will not diffuse out of the cell.
  • As a result,  photosynthesis will not take place and the plants will die due to lack of food and nutrients.

When the morning announcements call for you to rise to recite the pledge of allegiance, the signal to stand up on your feet is sent by the somatic nervous system. The somatic nervous system is <span>part of the peripheral nervous system. Its functions are : </span><span>voluntary movement of the muscles and organs and reflex movements.

Carbohydrates function in the diet to do which of the following
ad-work [718]

Answer:

carbohydrate like glucose, fructose, sucrose

they are either ketones or aldehyde

they can be of single. unit or made up of multiple units

carbohydrates are also called sugars because some are sweet and in daily life used as seeetner

what they do in body is provide fuel to body to carry out processes, helps in formation of atp and atp is used as energy currency

body doesn't let sugar come out of blood into urine

if its coming in urine we call it glucosuria

u may have diabetes if urine has glucose and protiens

aleksandrvk [35]

Methionine-methionine leucinelysine that a mutation in the DNA occurs so that the fourth base (counting from the 5' end) of the messenger RNA.

mRNA codons are read from 5' to 3' , and they specify the order of amino acids in a protein from N-terminus (methionine) to C-terminus. The mRNA sequence is: 5'-AUGAUCUCGUAA-5'

Ciodons which is broke the sequence into a series of three-nucleotide units. There are three-letter nature of codons that the four nucleotide found in mRNA such as  A, U, G, and C  all these can produce a total of 64 different combinations. The sequence of the tRNA anti-codon is 3'-UGC-5' and the tRNA will carry the amino acid which is the encoded by the codon.

Neurons have special proteins in their
Ilya [14]

Answer:

The ribosomes on the rough endoplasmic reticulum (RER) most likely produces neuronal special proteins.

Explanation:

Conduction of electrical impulses by action potentials of neurons takes place through controlled flow of charged ions through neuronal membranes. This ion transfer is controlled by specialized neuronal channel proteins which are present in the neuronal cell membrane.  

These channel proteins allow for hydrophillic passage of ions and water molecules across the neuronal membranes.  

Ribosomes that are attached to the RER are involved in protein synthesis. They carry the code for proteins carried by the mRNA and translate into respective protein.

The RER along with some free ribosomes cluster together as Nissl bodies and are mainly involved in neuronal specialized proteins.
