Answer:

Glucose: is a simple sugar which is an important energy source in living organisms and is a component of many carbohydrates.

Fructose: or fruit sugar, is a simple ketonic monosaccharide found in many plants.

Deoxyribose: sugar derived from ribose by replacing a hydroxyl group with hydrogen.

Ribose: is a kind of sugar that is produced by the body. It is used as a medicine. Ribose is used for heart disease, mental function, athletic performance, chronic fatigue syndrome (CFS), fibromyalgia, and many other conditions, but there is no good scientific evidence to support these uses.

Glyceraldehyde (glyceral) is a triose monosaccharide with chemical formula

based on what learned in bio202, arrange the following five events in an order that explains the mass flow of materials in the p
svp [43]

The correct order of the following events on the mass flow of materials in the phloem is:

  1. Leaf cells produce sugar by photosynthesis.
  2. Solutes are actively transported into sieve tubes.
  3. Water diffuses into the sieve tubes.
  4. Sugar moves down the stem.

Correct answer: letter C.

This is because the mass flow of materials in the phloem must pass through all these processes in a consecutive and orderly manner, from the cell to the stem, in order to allow nutrients and other vital materials to reach from the plant roots to the leaves and fruits.

<h3>How is this transport of nutrients and other vital materials achieved?</h3>

This is accomplished by the transport of solutes through the phloem's network of channels, which contain fluids, mineral salts, vitamins and other nutrients essential to plant health. Mass flow also helps distribute oxygen and carbon dioxide to all parts of the plant. These materials are necessary for plant respiration and growth.

Kipish [7]

A codon is a tree letter nucleotide sequence in the mRNA. The tRNA anticodon attached to the corresponding amino acid recognizes the mRNA codon. A single amino acid can have more than one codon. 

The serine codon can be one of the following:

The quantity of each type of organelle in a cell varies depending on the tasks the individual cell must perform. If a scientist
tester [92]

The correct answer is option C. A leaf growing in full sunlight

The chloroplast is an organelle, which helps the plants to carry out the process of the photosynthesis. The leaves are the main site of the photosynthesis in the plants, hence, they have an abundant number of chloroplasts present in the cells. In the presence of the sunlight, they perform the light dependent reactions of the photosynthesis process. In case, a scientist find out the cell, which have a high number of chloroplast, then the cell must be specialised to perform photosynthesis, hence, the cell would belong to the leaves, which are growing in full sunlight.
