Answer: Warm air rises and causes high air pressure. Cold air stays closer to earth and causes low air pressure which is known as low pressure. When there is a low-pressure system in the area- In contrast, a high-pressure system allows for rain clouds "I believe since water vapor is formed when water is heated and it can form when something heats".

The rest are taken, and I can't answer them because of the shortage and they dont make sense :(

Explanation: I'm sorry if im wrong, I'm just trying to be helpful.

What do the variables in the Hardy-Weinberg equation represent? p p2 q q2 2pq frequency of the homozygous recessive genotype arr

kompoz [17]

Explanation:

In Hardy-Weinberg equilibrium...

$p^{2} + 2pq +q^{2} = 1$

p represents the dominant allele frequency

q represents the frequency of the recessive allele

q^2 = the genotypic frequency of the homozygous recessive

p^2= the genotypic frequency of the homozygous dominant

2pq= the frequency of the heterozygous genotype

Further Explanation:

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences form new alleles, and affect the corresponding mRNA and thus the protein encoded. Along with genetic drift, selective mating and natural selection, evolution may occur within populations.

Some alleles become fixed within a population over time. In Hardy-Weinberg equilibrium for a specific gene that is not undergoing evolution- allelic frequencies are stable over several generations. During this period, mutations do not occur within the population.

lara31 [8.8K]

Answer:

The cytosol is best described as semifluid substance in which organelles are suspended.

Explanation:

Cells have different components. They can be divided in eukaryotic and prokaryotic. When it comes to the first type, they have a defined membrane for the nucleus. When it comes to the second ones, they have their nucleus in all the cytosol. <em>The cytosol is the space in the cell made of a semifluid subtance with different organelles suspended</em>.

Just to mention some of the organelles that can be there, we can find mitochondrion , endoplasmic reticulum , centriole , among others.

Verdich [7]

Answer:

You should never take shelter under a tree when lightening. You should get away from the tree and get as low down to the ground as possible. You do not always have enough time to get to a building so it depends on your surroundings/situation.
