If the birth rate and death rate are balanced in a population, how might a population increase in size?
lara [203]

Answer:

Population change is governed by the balance between birth rates and death rates. If the birth rate stays the same and the death rate decreases, then population numbers will grow. If the birth rate increases and the death rate stays the same, then population will also grow

Explanation:

Natural increase in a population occurs where Birth rate is greater than death rate. ... Natural decrease occurs when death rate is greater than birth rate. This means that more deaths occur in a population than babies are born so population numbers decline

Anastasy [175]
I think, Lipogenesis is a common for organic molecules because the intermediate Acetyl-CoA is formed in most metabolic processes. Lipogenesis involves the formation of fatty acids from Acetyl-CoA. Acetyl-CoA is an intermediate stage in metabolism of simple sugars, such as glucose, which is the preferred source of energy for most living organisms.

Should water be included in the model as a reactant or product? if so, how should it be included?
solong [7]

Water be included in the model as a reactant and a product

<u>Explanation:</u>

  • Reactants are the one that react together in a chemical equation. The product is the result formed due to the chemical reaction occurring between the reactants.
  • For example if natural gas is burnt the methane and the oxygen are the reactants. The product produced due to the chemical reaction is Carbon dioxide and water as the product.
  • For the production of ADP water acts with ATP to reduce Triphosphate to diphosphate. In this, it is the reactant and in chemical reaction the bonds are broken between the atoms and new bonds are produced between the products.

Assume that the mother's genotype is AZ/az, and the father's genotype is Az/aZ, and the recombination rate is 10%. What are the
Varvara68 [4.7K]

Answer:

.45 from mom, .05 from dad

Explanation:

Given that:

the mother's genotype is AZ/az

i.e AZ = 50%

az = 50%     (parental)

But  we  were also told that the recombination rate is 10% which will like wise affect the mother's genotype

So 100% -10% = 90 % of the mother's genotype

We have a new genotype

AZ = 45%

az = 45% (parental)

Therefore the probability of az gamete from the mother = \frac{45}{100}

= 0.45

Similarly; the genotype of the father is:  Az/aZ

This is an heterozygous father who is diploid hence, there is a remarkable presence of two copies of each autosomal chromosome.

Az is the allele of the genes in one chromosomes and aZ is the allele of the genes in the other.

The gametes of this self cross are: Aa, AZ, az, zZ

Therefore; the recombinants are:

AZ

az

Since there are 10% recombinant; then

AZ = 5%

az = 5%

Therefore the probability of az gamete from the father = \frac{5}{100}

= .05

Draw conclusions: how well did the punnett squares predict the offspring percentages for each parent pair?
rjkz [21]

<span>It may be subjected to the number of dissimilar genes in the punnet square. In the characteristic Aa v Aa square it is a 1:2:1 ratio, 25% AA, 50% Aa, and 25% aa. These percentages are autonomous of how many offspring, for instance if you have 3 in a row that are AA the probabilities that the next one will be AA are identical as in the original.</span>
