Answer:

c. limiting factor.

Explanation:

The limiting factors are environmental or ecological factors that act directly on the living beings of a population, limiting their size, since these factors determine their birth, mortality, migrations, etc. They are the ones that regulate the growth and expansion of a species.

If environmental factors are optimal for the development of a living being, they favor the growth of that organism in that biotope. But if any of these factors prevents the growth of a species, there is talk of a limiting factor.

Among these physical and chemical factors that determine the biotope include:

- Abiotic factors (do not depend on population density):

Climate:

Light. Only the most superficial organisms access it in water. On land, there is also competition in leafy areas to access it.

Temperature. Some living beings cannot live at the temperature that others live.

Water: It is necessary that it rains or that living beings can access water in order to live. If there is no water, they die.

Atmospheric pressure.

Non-climatic:

Soil factors: The chemical composition of the soil, its pH, salinity, etc. It makes some plant species may or may not survive in it.

Factors of the aquatic environment: The concentration of O2, dissolved CO2, the degree of salinity, the existence of currents, etc., limits the development of some organisms.

- Biotic factors (depend on population density):

Food. If they do not have enough food, the population will have to be smaller.

Interspecific relationships. The number of predators limits the number of prey, and vice versa.

Intraspecific relationships. The relationships established between individuals of the same species can also limit their existence.

What would be the anti codon in the tRNA for the amino acid trp (tryophan)?
MrRissso [65]
How do the genes in our DNA influence our characteristics? For example, how can a gene determine whether a person is an albino with very pale skin and hair? Basically, a gene is a segment of DNA that provides the instructions for making a protein, and proteins influence our characteristics. This chart describes how two different versions of a gene result in two different versions of a protein which in turn can result in either normal skin and hair color or albinism. DNA  Protein  Characteristic   Version of the gene that provides instructions to make normal protein enzyme  Normal enzyme that makes the pigment molecule in skin and hair  Normal skin and hair color Version of the gene that provides instructions to make defective enzyme  Defective enzyme that does not make this pigment molecule  Albinism (very pale skin and hair) A gene directs the synthesis of a protein by a two-step process. The first step is transcription of the gene in the DNA. Transcription produces a messenger RNA (mRNA) molecule. The second step is translation of the mRNA molecule. Translation produces a protein molecule. During transcription, the sequence of nucleotides in a gene in the DNA is copied to a corresponding sequence of nucleotides in mRNA. During translation, the sequence of nucleotides in the mRNA determines the sequence of amino acids in the protein. After translation, the sequence of amino acids in the protein determines the structure and function of the protein. Differences in protein function can influence characteristics such as normal skin and hair color vs. albinism.

1.Explain how the TATA box and transcription
jeka94

Answer:

The TATA box is an alternating sequence of Adenine and Guanine nucleotides that transcription factors bind to. The TATA box is found just before a gene. The transcription factors tell the RNA polymerase where to bind to begin transcription. This ensures the RNA polymerase will know where to start and which gene to transcribe.

Which structures that distinguish a eukaryotic cell from a prokaryotic cell are part of the internal membrane system?
Nat2105 [25]

Answer:

nuclear membrane, endoplasmic reticulum, Golgi apparatus, and vesicle

Explanation:

The structures or organelles in internal membrane system in the cell do all production, processing and secretion function together. A prokaryotic cell does not contain any membrane bound organelles but Eukaryotic cells do have. Nuclear membrane has double membrane and golgi-rendoplasmic reticulum and vesicle contain single membrane so all these organelles are membrane bounded.
