Answer:

Polar regions

Explanation:

Because plants don't survive in the extreme cold and ice that cover these regions year-round.

Due to their intense and harsh environmental circumstances, polar regions like the Arctic and Antarctica often have the lowest levels of biodiversity. So, the correct option is B.

The term "biodiversity", which is short for "biological diversity", describes the range of living things and ecosystems that exist on Earth. It includes a wide range of species, genetic diversity within those species, a wide range of environments, and a range of ecological processes. Humans benefit greatly from biodiversity as it provides them with food, medicine and ecological services such as pollination and water and air purification.

Because of their intense and harsh environmental conditions, polar regions such as the Arctic and Antarctica often have the lowest levels of biodiversity. These regions have a relatively limited diversity of species because the cold and dry conditions make it difficult for many species to live. Furthermore, these areas often have low population density due to the severe environment and scarce resources.

So, the correct option is B.

Answer:

Bacteria are prokaryotes, lacking well-defined nuclei and membrane-bound organelles, and with chromosomes composed of a single closed DNA circle. They come in many shapes and sizes, from minute spheres, cylinders and spiral threads, to flagellated rods, and filamentous chains.

Explanation:

Answer:

Prokaryotes,both bacteria and archaea have prokaryotes, which means that the cells don't have a nucleus or other membrane-bound organelles in their cells. Like bacteria, the cells have a coiled ring of DNA, and the cell cytoplasm contains ribosomes for the production of cell proteins and other substances the cell needs.

Telomerase is an enzyme that longs telomeres, which are fundamental repeats at the ends of chromosomes whose length is associated with cellular aging.

Telomeres are specific long tandem repeats located at the ends of all chromosomes in the cells.

These repeats (telomeres) are fundamental during cell growth and cellular aging.

It has been shown that telomerase can avoid the shortness of telomeres and thus can be used to slow cellular aging.

The statement embryonic stage is the first phase of the prenatal stage, lasting only two weeks after conception is false.

An embryonic stage may be defined as the period after implantation, during which all of the major organs and structures within the growing mammal are formed.

The first two weeks after conception are known as the germinal stage, not the embryonic stage. The third through the eighth week is known as the embryonic period, and the time from the ninth week until birth is known as the fetal period.

X-linked genes are inherited. The affected girl's father is hemophilic (X-Y), and the mother might be either hemophilic (X-X-) or carrier normal (X+X-).

These are the genes located in the X séx chromosome and not in the somatic ones.

Traits coded by these genes are inherited. This is, X-linked genes are transmitted from parents to children through generations.

According to this, X-linked genetic disorder will be inherited as well.

Hemophilia is a X-linked recessive genetic disorder.

Let us represent the recessive allele with the symbol -, and the dominant allele with the symbol +.

For the affection to be expressed, the person must be either,

If the baby girl is found to have inherited the trait from her parents, then her genotype is X-X-. She must have received one X- chromosomes from each parent.

Options,

Cross 1) affected father x carrier mother

Parentals)   X-Y    x    X+X-

Gametes)  X-      Y    X+     X-
