NemiM [27]3 years ago

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.

Identify the ways the ancient greek scientists pythagoras and euclid contributed to mathematics and science.
8_murik_8 [283]

Numerous scientific and technological advances were accomplished by the Ancient Greeks. Greek philosophers started to adopt new perspectives on the world. They developed hypotheses about how the universe operated and believed that the natural world adhered to a set of rules that could be observed and understood via research.

Pythagoras studied geometry. Pythagoras kept track of all the mathematical advancements that were accomplished in Greece over time. To determine the sides of a right triangle, he established the Pythagorean Theorem, which is still in use today.

Euclid was arguably the most significant Greek mathematician. Numerous works titled Elements were written by Euclid on the subject of geometry. For 2000 years, these texts served as the de facto reference on the subject. Sometimes referred to as the most influential textbook in history, Euclid's Elements.

In familial hypercholesterolemia, individuals homozygous for the allele causing the disorder completely lack receptors on liver
JulsSmile [24]

Answer:

The correct answer is - incomplete dominance.

Explanation:

A inheritance pattern that is characterized by pattern in which the one allele is not completely dominant over the its recessive variant of the allele and due to its incomplete dominance a third phenotype expressed over, termed as the incomplete dominance.

In the case of the familial hypercholesterlemia, it is genetic disorder in which the individual lacks the receptors on liver cells remove cholesterol from the blood. This condition occur in the homozygous allele case. In normal people have receptors normal while in heterozygous condition individual have half of the total receptors.

Thus, it is the case of incomplete dominance.

Novay_Z [31]

Answer: Most viruses can use host machinery to produce more of themselves

Explanation:

Since viruses carry out no metabolism themselves, they rely solely on the living cells of the host (organism they infect) to replicate and spread from cell to cell.

Thus, viruses do not kill the cells they infect since they need them, and use them to replicate more offsprings
