What organism(s) and processes led to O2 accumulation in our atmosphere?

1 answer:

7 0

Plants are the organisms that produce oxygen, or O2. To do this, they go through a process called photosynthesis. They take carbon dioxide, water, and sunlight, and convert it into oxygen and glucose (sugar). Without plants, you, me, your pet, and all other living organisms wouldn't have oxygen :) hope this helped!

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.

What is the estimated expected (mean) time for project completion?

il63 [147K]

The estimated expected (mean) time for project completion is 50 weeks, time management includes all the activities necessary to achieve the target date of delivery of the project. It includes the following activities: identification of activities, logical sequencing of activities, estimation of duration of activities, and preparation of the project schedule. For the preparation of the schedule we will see various methods such as resource leveling, simulation, and the critical chain method.
