Pioneer species are species that colonize previously uncolonized land, usually leading
to ecological succession. They are the first organism to start the chain of events
leading to a livable biosphere or ecosystem. Why is a lichen most likely to be a pioneer
species?

Answer:

This enables better survival and reproduction compared with other members of the species, leading to evolution. Organisms can adapt to an environment in different ways. They can adapt biologically, meaning they alter body functions.

Teams of scientists are digging fossils at each of the four locations shown in the diagram. The index fossils useful to scientists is It enables scientists to determine the age of the rock.

The index fossil is defined as the reference for determining the absolute age of the other fossils. The age of an index fossil can be determined using radioactive dating or another method that determines the absolute age of the index fossil.

Its age was used to calculate the ages of other fossils. An index fossil is a fossil that existed over a large geographic area but only for a short geologic time period. A trilobite is an excellent index fossil.

Therefore, Scientists are excavating fossils in each of the four locations depicted in the diagram. Scientists can use the index fossils. It allows scientists to calculate the age of the rock.

The circulatory and cardiovascular system are responsible for bringing nutrients and oxygen to all the cells, therefore, a complete blood count quantifies and evaluates different types of blood cells, while a complete blood count with differential consists in recognizing and assessing the proportions of the different varieties of leukocytes.

The cardiovascular system covers those structures (heart and blood vessels) that allow blood and lymphatic circulation (circulatory system).

It is a scheme that allows to represent the composition of the blood.

It is one of the tests that allows counting each of the leukocyte types.

Therefore, we can conclude that the circulatory and cardiovascular system are responsible for bringing nutrients and oxygen to all the cells, therefore, a complete blood count quantifies and evaluates different types of blood cells, while a complete blood count with differential consists in recognizing and assessing the proportions of the different varieties of leukocytes.

Answer:

Genetic diversity

Explanation:

Genetic diversity is when a population of a species, humans, in this case, have different genes between different individuals. One person may have blue eyes while the others have brown. This shows diversity within the gene pool.

Genetic diversity is also important to the survival of a species. Two-parent reproduction leads to genetic diversity. Having different alleles within a population allows for adaptation. On the other hand, one-parent reproduction does not allow for genetic diversity. This hinders the species because it does not let species to slowly improve the gene pool through natural selection and adaptation.

An irregularly shaped region within the prokaryotic cell that contains all or most of the genetic material.

The 16s rRNA gene encodes an RNA that would be used as a component of the ribosome during translation (Option c). It is a ribosomal RNA.

Ribosomal RNAs (rRNAs) represent fundamental components of the ribosomes, the protein factories of the cell.

Ribosomes play central roles during the process of translation by which an mRNA is used as a template to produce a polypeptide.

The 16S rRNA is a constituent of the bacterial small ribosomal subunit, which is used during translation.
