Shalnov [3]
<span>The most serious consequence of acute pancreatitis resulting from biliary obstruction is the development of circulatory shock.</span>
<span>In rare cases, acute pancreatitis can lead to necrosis of pancreas tissues. Pancreatic enzymes may get into the bloodstream and cause inflammation and damage to other organs which then can lead to shock, respiratory failure, kidney failure and other complications. This is a very serious situation which can be fatal.</span>

Explain why a hydrogen atom can become either an ion or a part of molecule?
NikAS [45]

<span>If it loses that 1 electron (0 electrons, 1 proton, 1 neutron) it become an ion that is positively charge because it has more protons than electrons. [Ignore the neutrons] </span>

<span>If it gains an electron (2 electrons, 1 proton, 1 neutron) it becomes an ion that is negatively charge because it has more electrons than protons </span>

<span>A molecule - when 2 or more "different" elements combine or when 2 or more of the "same" elements combine </span>

<span>1 proton 1 electron <----- that is considered to be neutral </span>

<span>3 protons, 3 electrons <----- neutral </span>

<span>5 protons 5 electrons <----- neutral </span>

<span>6 protons, 5 electrons <-- positive ion [more protons than electrons] </span>

<span>5 protons, 8 electrons <--- negative ion [more electrons than protons] </span>

An allosteric protein demonstrates a decrease in its Kg for molecule Y as the concentration of molecule X increases. Based on th
djyliett [7]

Answer:

X is negative heterotropic modulator

Explanation:

In allosteric regulations, modulators are molecules that causes a change in the conformation of an enzyme, hence, resulting a change in enzyme activity. It can lead to a decrease or an increase of the enzyme.  When a molecule decreases the enzyme activity it called a negative modulator, when it increases or activates the enzyme activity, it is called a positive modulator.

A positive or negative modulator can either be homotrophic (substrate acts as modulator) or heterotropic (another ligand acts as modulator).

In the example above, X is negative heterotropic modulator, because the modulator is different from the substrate and it also decreases the enzyme activity.

4. Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If t
lisov135 [29]

Answer:

The correct answer would be:

  • Genotype ratio: 1 (PP) : 2 (Pp) : 1 (pp)
  • Phenotypic ratio: 3 (polka-dot tails) : solid colored tail

The genotype of both parents is Pp (heterozygous).

Thus, both the parent would produce two types of gametes which are P and p.

The cross would result in the production of offspring with three types of genotype PP, Pp, and pp in 1:2:1.

Offspring with PP and Pp will have a polka-dotted tail as it is the dominant trait.

Thus, the phenotype ratio would be 3 (polka-dotted tail) : 1 (solid colored tail).
