The answer is; C

Fossil fuels are the remains of an organism  that lived in the past and have been preserved  or their impression has been preserved. Fossils are studied to identify the difference (genetic and phenotypic) between past and future related organism  and are carbon dated to determine the time in which the organisms existed. The study of fossils is called paleontology.

In the hypothesis that C. stellatus (a species of barnacle) is competitively excluded from the lower intertidal zone by B. balan
lord [1]
<h2>Competitive exclusion principle.</h2>

Explanation:

The fundamental and realized niches of B. balanoides are identical, but the fundamental and realized niches of C. stellatus are different.

All the possible combination of resources and condition under which a species can grow, survive and reproduce is called its fundamental niche. Whereas, the more limited set of resources and condition under which a species can grow, survive and reproduce in the presence of competitors and predators is termed as its realized niche.

Competitive exclusion principle states that if two competing species coexist in a stable, homogeneous environment, then they do so as a result of differentiation in their realized niche.

<em>B. balanoides</em> can use a wider range of resources than<em> C. stellatus </em>because its fundamental and realized niches are identical . Hence thrives to exclude C.stellatus.

Why is osmosis important to the survival cell​
Rudiy27

The most important function of osmosis is stabilising the internal environment of an organism by keeping the water and intercellular fluids levels balanced. In all living organisms, nutrients and minerals make their way to the cells because of osmosis. This obviously is essential to the survival of a cell.

A(n) ____________________ is a sequence of organic nitrogen base pairs that codes for a polypeptide or a protein.
horsena [70]

A(n) <u>gene</u> is a sequence of organic nitrogen base pairs that codes for a polypeptide or a protein.

What is polypeptide?

Peptides are made up of short chains of amino acids joined together by peptide bonds. The word "peptide" comes from the Ancient Greek word "peptós," which means "digested." Oligopeptides, which comprise dipeptides, tripeptides, and tetrapeptides, are chains of fewer than twenty amino acids.

A polypeptide is a peptide chain that is longer, continuous, and unbranched.

 Therefore, along with nucleic acids, oligosaccharides, polysaccharides, and others, peptides belong to the large chemical families of biological polymers and oligomers.

A protein is a polypeptide that has more than 50 amino acids, on average. A protein is made up of one or more polypeptides that are structured in a biologically useful manner. Proteins are frequently coupled to other proteins, other macromolecules like DNA or RNA, or complex macromolecular assemblies.

Researchers can manipulate the genes of a mouse so that a single gene in a single tissue either produces an inactive protein (a
s2008m [1.1K]

Answer:

1) The genetic changes can lead to a reduction in the capacity of the mice to move glycogen at its branches points and lowers blood glucose levels between meals.

2) Genetic changed can lead to a decrease in the capacity to lower blood glucose due to the knock out of the hexokinase gene leading to elevated levels in the bloodstream.

(c) A knockout of FBPase2 will result in elevated levels of fructose-2,6-bisphosphate in

liver favoring the glycolytic pathway and inhibiting gluconeogenesis by the decrease of fructose 1,6-

bisphosphatase-1 activity

(d) An active FBPase-2 will now favor gluconeogenesis and this inhibits glycolysis. I.e. a decrease in PFK-1 activity while increasing FBPase-1 activity simultaneously.
