Biology

Stels [109]3 years ago

Answer:

A living being or organism is a complex set of organizational material, in which molecular communication systems intervene that relate it internally and with the environment in an exchange of matter and energy in an orderly manner, having the ability to perform the basic functions of life that are nutrition, relationship and reproduction, in such a way that living beings work by themselves without losing their structural level until their death.

Explanation:

The matter that composes living beings is formed in 95% by four elements (bioelements) that are carbon, hydrogen, oxygen and nitrogen, from which biomolecules are formed: 3 4

Organic biomolecules or immediate principles: carbohydrates, lipids, proteins and nucleic acids.

Inorganic biomolecules: water, mineral salts and gases.

These molecules are constantly repeated in all living beings, so the origin of life comes from a common ancestor, as it would be very unlikely that two living beings with the same organic molecules have independently appeared.5 6 Stromatolites have been found 3700 million years old, 7 so that life could have arisen on Earth 4100-3800 million years ago.1 8 9

All living things are made up of cells. Inside these are carried out the sequences of chemical reactions, catalyzed by enzymes, necessary for life.

The science that studies living things is biology.

Tanya [424]

Answer:

The correct answer is D) assimilation of external DNA into a cell

Explanation:

A bacteria is called transformed when it consist a genetic material that is not it's own but taken from outside the cell. So transformation of bacterial cell defines the uptake of foreign DNA by bacterial cell from its surrounding.

This transformation in bacteria is necessary because it provides bacteria some new and extra genes that help it to survive in the adverse and changing environment.  

Transformation can result in getting the antibiotic-resistant gene to the bacteria which protect the bacteria from antibiotics during infection when antibiotic is used against it.

So the right answer is D) assimilation of external DNA into a cell.

Which variable is likely to undergo the largest change in value resulting from a mutation that introduces a new allele into a po
dsp73

Answer:

b. average heterozygosity

Explanation:

From the available options:

a. nucleotide variability

b. average heterozygosity

c. average number of loci

d. geographic variability

Nucleotide variability represents a form of genetic variation that occur as a result of difference in nucleotide sequence of deoxy ribonucleic acid.

The locus is a region on the chromosome where genes are located. Average number of locus thus refers to total number of loci per total number of individuals in a population.

Geographic variability refers to difference in genetic traits across the various geographical distribution of a population.

Average heterozygosity is the percentage or proportion of heterozygous individuals for a trait within a population. It is a common measure of genetic variation in a population.

When a mutation occur within a population and this leads to the introduction of a new allele at a locus for which some individuals within the population are homozygous, it will directly affect the average heterozygosity of the population because more individuals will lose their homozygosity and become heterozygous.

<em>The correct option is b.</em>
