1.) Photosynthesis and cellular respiration are often described as been chemically opposite because the product of the photosynthesis process is the reactant of the cellular respiration process and vice versa.

<em>The reactants of cellular respiration are glucose and oxygen and these happen to be the products of photosynthesis also. During the process of photosynthesis, plants take in carbon dioxide and water in the presence of sunlight to produce glucose and oxygen. During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water, which are the reactants of the photosynthesis process. </em>


2.) Photosynthesis and cellular processes are related to each other, this is because, the photosynthesis process produces the glucose, which cellular respiration used to synthesis energy in the cells of living organisms. <em>Thus, the glucose producing plants depend on the living organisms that carried out cellular respiration to produce carbon dioxide and water, which is the necessary reactants for photosynthesis process. The organisms using cellular respiration also depend on plants to produce glucose and oxygen for their use.</em>

Hope this helps,

There are 20 naturally occurring amino acids, therefore, there are only 20 mRNA codons. True or false
weqwewe [10]

Answer:

False. There are 20 amino acids, but 64 possible codons.

Explanation:

Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.

The codons indicating the initiation or stop points during the translation process are:

• The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG.

• The end codons are UAA, UAG, UGA.

What is the relationship between the cytoplasm and nucleus of a cell
Olegator [25]

Answer:

The nucleus is a cell's central organelle, which contains the cell's DNA (Figure 3.6). The cytoplasm is composed of two parts, the cytosol and organelles. Cytosol, the jelly-like substance within the cell, provides the fluid medium necessary for biochemical reactions.
