Answer:

If the question is referring to Mendel's postulates, all options are correct

Explanation:

Gregor Mendel discovered that certain components he called UNIT FACTORS determine inheritance. This unit factors were later described to be genes in modern genetics. He discovered that an organism receives two forms of this unit factors from each parent, which he called ALLELES. In his experiments, he observed that one of the pair of alleles have the ability to mask the expression of its variant pair. He called the allele that masks, DOMINANT allele while the allele that is masked, RECESSIVE allele.

During his cross experiment, he discovered that the alleles of a gene (unit factor) separates into gametes, he called this LAW OF SEGREGATION. He notably discovered in his cross involving two different characters that the segregation of the alleles of one gene into gametes does not influence the segregation of the alleles of the other gene. He termed this his LAW OF INDEPENDENT ASSORTMENT.

algol13

Answer:

Changes that occur in species, over a long period of time and that include the the replacement of unfavorable characteristics by helpful variations lead to evolution (second option).

Explanation:

Evolution, in terms of biology, consists of the genetic, anatomical and functional changes that occur in individuals of different species, acquiring useful characteristics that replace unfavorable characteristics, due to processes such as natural selection, proposed by <u>Charles Darwin</u>.

<u>Biological evolution</u> raises the existence of a common ancestor, from which all current known species are known, and an evolutionary line for each of those species. Evolution is considered the basis of <u>biodiversity</u>, due to the genetic changes it has produced over many years.

Why doesnât gastric juice digest the inside of the stomach?
arlik [135]
The inside of a stomach is coated with a lining that protects it.
This lining is made up of cells called epithelial cells. They coat the stomach with a mucus that neutralizes the acid.

The mucus contains bi-carbonate (a base), similar to baking soda.
Acid + Base = water and salt
So, that’s why taking tums or swallowing baking soda water helps an upset stomach.

When your stomach is upset, it means there’s too much acid. Taking a tums neutralizes that overproduction eating also helps to absorb the excess acid.
