What biomolecule determines whether an individual inherits the inability to produce the enzyme needed to break down the amino ac
julsineya [31]

Answer:

NUCLEIC ACIDS

Explanation:

Four biomolecules are found in living systems and they are responsible for every process undergone by cells of living organisms. Nucleic acid is one of the four biomolecules, which is the precursor of another biomolecule called PROTEIN.

DNA and RNA are the two nucleic acids which contains segments called GENES that encodes the information needed for the synthesis of proteins and transfer of this information to offsprings. Genes found on nucleic acid biomolecules undergo expression to produce proteins. ENZYMES are proteinous molecules that catalyse biochemical reactions in living systems.

From the explanation above, this means that ENZYMES that catalyze reactions like breaking down amino acids are PROTEINS, which in turn are made from GENES carried by NUCLEIC ACID biomolecules.

Therefore, NUCLEIC ACIDS determine whether an individual inherits the inability to produce the enzyme needed to break down the amino acids

How are grasslands formed?
agasfer [191]

Answer:

Grasslands arose during the period of cooling and drying of the global climate, which occurred during the Cenozoic Era (65.5 million years ago till present).

Grasslands  are said to be in between a forest and a desert when it comes to rainfall ( they do not receive enough rainfall to grow trees like a forest but they contain lots of grass so they receive more rain than a desert)

Hypothesize what potential impact a mutated EGFR allele will have on a cell. Give one possible impact and explain your answer.
NemiM [27]

Answer/Explanation:

EGFR stands for epidermal growth factor receptor. It is a transmembrane protein acting as a tyrosine kinase receptor for epidermal growth factor ligands, which are associated with promoting cell division and proliferation. When epidermal growth factor binds to the receptor, it becomes activated and undergoes dimerization and autophosphorylation.

A mutation could occur making the receptor overactive. That is, it does not require ligand binding to become activated, meaning it is always in an "on" state. This would lead to uncontrolled proliferation, a hallmark of cancer.

B) They all require the same type of food. 
C) They are part of a community.
D) They are abiotic factors in a forest.</span>

The answer is C. A community is the summation of all the species population interacting in a habitat/ecosystem. These interaction between the population could include commensalism, predation, symbiosis, parasitism, and etcetera.
