In what areas of the world is biodiversity the lowest?
tropical regions
polar regions
temperate regions
ocean regions
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.
What is Biodiversity?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.

Telomere shortening puts a limit on the number of times a cell can divide. Research has shown that telomerase can extend the life span of cultured human cells. How might adding telomerase affect cellular aging?.
Telomerase is an enzyme that longs telomeres, which are fundamental repeats at the ends of chromosomes whose length is associated with cellular aging.
What are telomeres?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.

what type of cell are bacteria and archaea made of ?
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.

What is the main reason that it takes 2 to 3 minutes for the reaction to occur between sucrose and sulfuric acid in the dehydration of sucrose? the activation energy needs to be overcome in the reaction. the activation energy must be removed from the intermediates. the sulfuric acid has to be consumed before the reaction takes place. the sucrose molecules must rearrange to become the catalyst.
The main reason for this activity is the activation energy needs to be overcome in the reaction.
What do you mean by Dehydration?Dehydration may be defined as a process where there is a removal or loss of water takes place from something.
When the reaction between sucrose and and sulfuric acid is carried, it may leads to dehydration of sucrose. As a result of this, activation energy requires to come up in the reaction.

16. Why should the recessive phenotype be used first to determine the q squared value instead of the dominant phenotype to determine the p squared value?
The recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.
What is a recessive phenotype?A recessive phenotype is a phenotype which expresses the recessive trait of a gene.
The recessive phenotype is always h0m0zygous for that triat to be expressed.
In the Hardy-Weinberg equilibrium equation, the allele and phenotype frequencies are given as follows:
p^2 + 2pq + q^2 = 1where;
p^2 is the h0m0zygous dominant phenotype frequency2pq is the heterozygous phenotype frequencyq^2 is the h0m0zygous recessive phenotype frequencyTherefore, the recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

Hemophilia is an X-linked recessive genetic disorder. A baby girl is found to have inherited the trait from her parents. What are the phenotypes of the parents?
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-).
What are the X-linked genes?
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.
Men have a high probability of being affected since they only have one copy of the X chromosome. In women, the effect of the mutation might be musk in heter0zyg0us state.Hemophilia is a X-linked recessive genetic disorder.
Let us represent the recessive allele with the symbol -, and the dominant allele with the symbol +.
X- is the chromosome carrying the recessive allele X+ is the chromosome carrying the dominant alleleFor the affection to be expressed, the person must be either,
X-X- ⇒ woman/girlX-Y ⇒ man/boyIf 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.
Her father provided the X chromosome, so he must be hemophilic (X-Y)Her mother provided the other X chromosome, but she can be either a carrier (heter0zyg0us, X+X-) or hemophilic (h0m0zyg0us recessive, X-X-).Options,
Cross 1) affected father x carrier mother

F1) 1/2 = 50% of the progeny is expected to be healthy (25% X+X- girls + 25% X+Y boys)
