What product produced by yeast cells during fermentation causes bread to rise?

All parts of fungi are composed of ____________ , or thin filaments of cells, packed closely together to form the main body of a

MAVERICK [17]

The right answer is hyphae for the first gap, mycelium for the second gap.

The hyphae constitute the vegetative apparatus of the mushrooms, while the visible part, that which is improperly called mushroom, is in fact its reproductive apparatus.

Hyphae are less branched filaments consisting of a single cell that can be several centimeters long. They contain several nuclei and can sometimes be partitioned.

The mycelium is a part of the mushroom (composed by many hyphae), which is in the form of white filaments and grows about fifteen centimeters under the ground. It is this part of the mushroom that has therapeutic properties because the filaments of the mycelium are going to draw the minerals in the soil.

In humans, Rh-positive individuals have the Rh antigen on their red blood cells, while Rh-negative individuals do not. If the Rh

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. It also specifies that these equilibrium frequencies can be represented as a simple function of the allelic frequencies at that locus. 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 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.

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

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.

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

predict what might happen to a population that is experiencing little immigration and emigration, low birth rate, and high death

bezimeni [28]

The population will later, cease to exist.

Since the population is experiencing (about) the same rates of immigration and emigration, these 2 factors will not change anything.

A low birth rate and a high death rate means that more people are dying than being born.

Therefore the population will decrease until there is nobody and it will cease to exist.

Many genetic technologies involve the transferring of genes from one organism to another. For example, a gene in human DNA codes

valentinak56 [21]

Answer:

The universality of genetic code.

Explanation:

The DNA is a molecule made up from 4 different nucleotides (A, T, C or G). The sequence in which these nucleotides are ordered constitute a code that gives a cell instructions to produce a specific protein. This is called the genetic code.

Every three nucleotides code for a specific amino acid. For example, ACG codes for Arginine, CUC codes for Proline, and so on.

The genetic code is universal. This means that in all living organisms, a particular sequence of three nucleotides will code for the same amino acid. This property guarantees that the human gene that codes for human insulin will also code for human insulin in bacteria.
