2 answers:

7 0

<span>The fourth level of cell organization is the organ level. The organ level is a structure composed of collections of tissues that perform specific functions in a living organism. Organs that are found in a human body are the heart, lungs, brain, pancreas, liver, among others. These organs perform specific functions and work in an interconnected manner for the human body to function well. When organs work together, they are called organ systems which are already the fifth level of cell organization.</span>

Describe an arctic summer

aev [14]

<span>Summer temperatures in the Arctic remain cool, fluttering around zero in many places, from June through September. In fact, Arctic residents must frequently heat their homes all year long. Neighbourhoods near the sea tend to remain close to 0°C throughout the summer, but inland areas, particularly in the south, regularly reach 7°C–13°C, and hardly as much as 20°C. One reason for the opposition is that the sea ice, which gradually melts, consumes much of the sun's energy, giving little to heat the air over it.

Hope this helped! :)</span>

Perhaps the single greatest contribution Linnaeus made to science was his method of naming species. This method, called binomial

ehidna [41]

Answer:

Binomial nomenclature is the naming system developed by Carolus Linnaeus. In this system, latin language was used because it is a dead language which cannot be spoken by people in the world. In binomial nomenclature, two names are used. One for genus and the second for specie. For example, Rana tigrina is the scientific name of frog. In this name rana is genus and tigrina is specie.

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.
