Answer:

ANIMALS: There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell's mass.

PLANTS: The three main classes of macromolecules found in plants are thus proteins, polysaccharides and nucleic acids. However, mixed polymers are also known. such as the glycoproteins, which contain both sugars and amino acids in covalent linkage.

I think it would be more like a book of blue prints because you have so much in your DNA like a book but one blue print just shows you one structure.

Answer:

11. b.

Explanation:

Photosynthesis stores energy in carbohydrates, cellular respiration releases energy from carbohydrates.

Glucose, C₆H₁₂O₆, is a carbohydrate.

Write out the equations:

Photosynthesis

carbon dioxide + water + light energy => oxygen + glucose/sugar

CO₂ + H₂O + light => O₂ + C₆H₁₂O₆

The carbohydrate is stored in the plant until it needs it, like to perform cellular respiration.

Cellular Respiration

oxygen + glucose/sugar => carbon dioxide + water + ATP energy

O₂ + C₆H₁₂O₆ => CO₂ + H₂O + ATP

The carbohydrate is used to make energy. Energy is released from carbohydrates.

Glucose, C₆H₁₂O₆, is a carbohydrate.

Fault in other options:

a. Photosynthesis and cellular respiration both occur in plants. Plants have mitochondria for cellular respiration.

c. Photosynthesis uses carbon dioxide and cellular respiration releases carbon dioxide.

d. Photosynthesis uses carbon dioxide, cellular respiration uses oxygen.

Researchers may be able to induce adult cells to behave like ______, an important advance in stem cell therapy.

ANEK [815]

Researchers may be able to induce adult cells to behave like embryonic stem cells an important advance in stem cell therapy.

Embryonic stem cells :

Embryonic stem cells are found in the inner cell mass of the human blastocyst, an early stage of the developing embryo lasting from the 4th to 7th day after fertilization. In normal embryonic development, they disappear after the 7th day, and begin to form the three embryonic tissue layers.

How embryonic stem cells are obtained?

Stem cells are now being collected from human embryos. In most cases, the embryos that are used have been aborted or left over from in vitro fertilization procedures. Although not technically feasible at this time, researchers expect that it is possible to clone stem cells from a patient's own somatic cells.

Cell therapy :

Cellular therapy (CT) is the transplantation of human cells to replace or repair damaged tissue and/or cells. With new technologies, innovative products, and limitless imagination, many different types of cells may be used as part of a therapy or treatment for a variety of diseases and conditions.
