Four types of membrane proteins are Integral Membrane Protein, Peripheral Membrane Protein, Transmembrane Protein, and Integral Monotopic Proteins. Their functions are to transport stuff, signal stuff, and others.

kupik [55]
Rapid consumption of alcohol in a very short period of time is very dangerous; due to delayed absorption the drinker will not know how really drunk he is and intoxication from that kind of drinking can last for days and even weeks.

bixtya [17]

Answer: 60%

Explanation:

In population genetics, the Hardy-Weinberg Principle states that the genetic composition of a population remains in equilibrium as long as no natural selection or other factors are active and no mutations occur.

The frequencies of the genotypes of an individual locus will be set to a particular equilibrium value.<u> It also specifies that these equilibrium frequencies can be represented as a simple function of the allelic frequencies at that locus</u>. In the simplest case, with a locus with two alleles A and a, with allele frequencies of p and q respectively, the principle predicts that <u>the genotypic frequency for the dominant homozygous AA is p^2, that of the heterozygous Aa is 2pq and that of the recessive homozygous aa, is q^2. The allele frequency of a is represented as p and the frequency of recessive allele is q.</u>

The three genotypes AA : Aa : aa appear in a ratio p² : 2pq : q². If we add them up, we get the unit:

p^2 + 2pq + q^2 = (p + q)^2 = 1  

And p + q = 1

<u>Rh-positive genotypes are represented as AA (homozygous dominant) or Aa (heterozygous) since the presence of a single dominant allele is sufficient to express the phenotype. While Rh-negative genotypes are represented as aa. </u>

If 84% of the population is Rh-positive, that means that this percentage includes all those who are AA and Aa. Then 16% are aa.

F(aa)=q^2=0.16

then F(a)=q=0.4

And since p + q = 1, p + 0.4 = 1, then p is 0.6

We can also calculate the rest, then F(AA)=p^2= 0.36

So F(Aa)= 2pq = 2 x 0.6 x 0.4 = 0.48

Notice that 0.36 + 0.16 + 0.48 = 1

Rashid [163]

Answer : Option A) He asked what would happen if he deliberately inoculated someone with cowpox fluid from another person.

Explanation : Edward Jenner wanted to know what would happen if he deliberately inoculate the cowpox fluid from some person to another. He tested this experimental results and later on came up with the hypothesis. Which roughly state that someone will not get smallpox because they already had cowpox.

How does variation of beak type affect a birds ability to survive?
Blababa [14]
The variation in beak type enables the different individuals in a population to feed on different food sources.

The shape of the beak is key to determining the primary food source of the bird. Certain birds species have specialized beaks, but within populations of those species, there is a variation in beak shape.
This gives the population the ability to respond to changes in the environment and availability of different food sources.
For example, if because of a dry period there is a shortage of fruit, some individuals in the population have the beaks that enable them to feed on other things, survive and leave offspring.
