Answer:
They are all carbohydrates.
Explanation:
Homo polysaccharides include starch, glycogen, and cellulose (same type of sugar-all made of glucose).
1- Amylose and Amyloprotein are the components of starch. Amylose is a branched chain with alpha 1–4 and alpha 1–6 at the branch point, whereas Amylopectin is a linear chain with alpha 1–4 and alpha 1–6 at the branch point.
2- Glycogen is created by forming a branched chain from glucose at alpha 1–6. It has a lot of branches.
3- Cellulose is a linear chain of glucose molecules with beta bonds.
Starch and glycogen serve as short-term energy stores in plants and animals, cellulose found in plant cell wall only.
Growth factors are cell-surface receptor-binding proteins that encourage the growth and development of target cells.
<h3>What is Growth Factor ?</h3>
A growth factor is a naturally occurring chemical that promotes cell proliferation, wound healing, and, on rare occasions, cellular differentiation. It is usually a secreted protein or a steroid hormone. Growth factors play a crucial role in the regulation of many cellular processes.
- A growth factor is a protein that stimulates the growth of specific tissues. Growth factors are found in a wide variety of animals, including insects, amphibians, humans, and plants, and they serve a crucial role in encouraging cellular differentiation and cell division.
- Growth factors are commonly used as a signaling molecule between cells. Cytokines and hormones, for example, attach to specific receptors on the surface of their target cells. As a result, the correct answer is proteins that bind to surface receptors and excite target cells.
Growth factors are local regulators that - bind to cell-surface receptors and stimulate growth and development of target cells.

A rough endoplasmic reticulum has ribosomes on it's surface. A smooth ER does not.
Answer:
Genotype: 100% or 4/4 of the progeny will be heterozygous for the trait, Yy.
Explanation:
<u>Available data:</u>
- Two plants differ in the seed color they produce.
- One plant produces green seeds, the other produces yellow seeds.
- Yellow is the dominant phenotype, over green which is the recessive phenotype
- The parental plants are true-breeding
Let us say that the allele Y expresses yellow color and is dominant over the allele y which expresses the green color and in the recessive one.
Cross: a green-seeded plant with a yellow-seeded plant
Parental) YY x yy
Phenotype) Yellow seeds Green seeds
Gametes) Y Y y y
Punnet square) Y Y
y Yy Yy
y Yy Yy
F1) Phenotype: 100% of the progeny will be yellow-seeded
Genotype: 100% or 4/4 of the progeny will be heterozygous for the trait
