What is the primary reason the signaling molecule is not received by every cell nucleus? Option 1: Cell nuclei have varying sizes. Option 2: The signaling molecule is too large. Option 3: Not all cells have receptors for the molecule. Option 4: The molecule is rapidly degraded.

Answers

Answer:

3. Not all cells have receptors for the molecule.

The main reason a signaling molecule is not receive by every cell nucleus is that not all cells have receptors for that particular molecule. Cells have specific receptors on their surface to recognize and respond to their corresponding signaling molecule. Cells that lack the specific receptors for a given signaling molecule will not respond to it, regardless of the size of the cell nuclei or other factors such as the stability of the molecule itself.

Toxic waste spills are a direct source of water pollution.
a. True
b. False

Answers

There are twotypes of sources of water pollution; the direct sources and indirect sources. Directsources include effluent streams from factories, refineries, was treatment plantsand others. Whereas for indirect sources, includes contaminants that enter the watersupply from soil or groundwater systems and from the atmosphere via rain. Most ofthese sources derive from human activities. Toxic waste spills are by-productsfrom the industrial plants or factories. It is a direct source of waterpollution. The answer is true.
Toxic waste spills are a direct source of water pollution.

What do bacteria have in common with the cells of other living organisms

Answers

Answer:

Bacteria and other living cells have some universal features that are, they are present in all the living cells.

These features include:

Plasma membrane: The lipid bilayer which separates the cell from the external environment. It is present in all the living organism.

Cytoplasm: It is a gel-like substance present within the plasma membrane of the cell (excluding nucleus). It contains and supports all the cell organelles and cell parts.

Ribosome: It is a vesicular structure made up of protein and ribosomal RNA. It is the main site of protein synthesis in all the cells. Prokaryotes generally contain 70S ribosomes and eukaryotes generally contain 80S ribosomes.

Genetic material: All the living organisms contains genetic material (usually DNA) either confined in the nucleus or floating freely in the cytoplasm.
They have ribosomes.They contain cytoplasm.
Some things bacteria have in common with cells of other livingorganisms is they both have chromosomes, they both have organellesand a nucleus, and are alive.

The developmental period during which a being grows from a single cell to an organism complete with brain and behavioral capabilities in 9 months is called

Answers

Answer:

Prenatal development

Explanation:

Prenatal development is the phase of growth and development in which a single-celled zygote grows into an embryo followed by the fetus and then a baby in the womb of a lady.

The process of prenatal development is very complicated which is divided into three phases:

1. Germinal phase: during the first two weeks after the conception in which the single-celled zygote develops.

2. Embryonic period: during which the zygote grows into the embryo and lasts from the second week to the eighth week.

3. Fetal period: During which the embryo grows to form a fetus which matures into a baby and is born.

Thus, Prenatal development is the correct answer.

Answer:

Prenatal.

Explanation:

The sexual reproduction may be defined the process of fusion of the male sperm and female ovum that leads to the formation of the zygote. Zygote is diploid in nature.

The prenatal development includes all the stages that are involved in the development of the single cell till the completion of the nine months of the fetus. The development of all organs and the process of the cell specification all occurs in the prenatal development stage.

Thus, the answer is prenatal.
