Gorging oneself after a period of starvation and then purging the body through induced vomiting and further fasting is a major s

Nastasia [14]

The correct answer is bulimia.
Bulimia is an eating disorder where a person eats as much food as they can, only to throw up everything they have eaten - they induce themselves to vomit to get rid of all the food they took.
Anorexia doesn't necessarily involve vomiting. Hypertension is high blood pressure. Obesity refers to extremely overweight people.

In rabbits, short hair is due to a dominant allele, S, and long hair to its recessive allele, s. Black hair is due to a dominant

Natali5045456 [20]

Answer:

SsBB x SsBB

or

SsBB x SsBb

Explanation:

SS- short hair

ss - long hair

BB- black hair

bb- white hair

Total the number of offspring produced = 2518+817=3335

Where 2518= short haired, black offspring SSBB or SsBb

817= Longed Hair, black offspring ssBB or ssBb

To get the offspring proportion for short hair black offspring

2518/3335×100 = 75.5%

long-haired, blackoffspring =817/3335×100 = 25%

This gives ratio of 3:1 as against the proposed dihybrid phenotypic ratio of Mendel experiment 9:3:3:1

Now, if you remember a dihybrid cross results in 9:3:3:1 phentoype ratio. That is when both parents are heterozygous for both alleles. So we can rule that out since it doesn't match our 3:1 ratio.

Since all the offspring are black , it means one parent is homozygous dominant for black and the other parent is either homozygous or heterozygous for the black allele.

Since the ratio is 3:1, for the hair length

That leaves us with the short hair. Since the ratio is 3:1, both parents are heterozygous for hair length.

Therefore, the possible parental genotype is

SsBB x SsBB

or

SsBB x SsBb

Describe alternating current and direct current. Include two ways that they are alike

Vilka [71]

AC can be produced by using a device is called as an alternator. This device is a special type of electrical generator designed to produce alternating current. A loop of wire is rotated inside of a magnetic field, which induces a current along the wire.

A sodium-potassium pump _____. moves three potassium ions out of a cell and two sodium ions into a cell while producing an atp f

SVETLANKA909090 [29]

Move three sodium ions out of a cell and two potassium ions into a cell while consuming an atp for each cycle

Explanation:

By pumping three (3) Na+ to the outside and two (2) K+ to the inside of the cell, there is a net positive charge on the outside leaving the inside of the cell electronegative. This process is achieved by the Na+/K+ pump and is a process that consumes ATP energy.

This is much more important in a neuron cell who ¾ of its energy is used to maintain a -70mV resting potential that is important for the nerve to pass impulse when depolarised.

In other cells, the gradient created in important in maintaining the homeostatic osmolarity inside the cell to avoid swelling and lysis of cells due to uptake of excess water by osmosis. The Na+ gradient is also used to import other molecules into the cell such as glucose and amino acids. These molecules are coupled with Na+ and then are absorbed efficiently as the Na+ flow back inside the cell down the Na+ concentration gradient.
