Answer:

Based on experiment, since that microorganisms are obligate anerobes, they will likely to accumulate or settle at the top of the medium since they are strictly living with the presence of oxygen or toxicated with no presence of oxygen.

In a population of plants, the allele for long stems is completely dominant over the allele for short stems. If 35% of the popul

KatRina [158]

Assumptions:
1. Equilibrium has been reached for the allele proportions
2. Absence of evolutionary influences such as mate choice, mutation, selection, genetic drift, gene flow and meiotic drive.

Defining L=long stem, l=short stem, and L is dominant over l.
f(x) = frequency of allele x (expressed as a fraction of population)
Then the Hardy-Weinberg equilibrium law applies:
p^2+2pq+q^2=1
where
f(LL)=p^2
f(Ll)=2pq
f(ll)=q^2

Given f(ll)=0.35=q^2, we have
q=sqrt(0.35)=0.591608
p=1-q=0.408392
=>
f(Ll)
=2pq
=2*0.408392*0.591608=0.483216
= proportion of heterozygous population

Answer: percentage of heterozygous population is 48.32%

A nurse is caring for a client receiving oxygen therapy. what is the expected reference range when obtaining oxygen saturation l

Elena L [17]

The expected reference range when obtaining oxygen saturation level is 95%-100%.

The four reasons as to why the reference range may be lower is due to the following;

- Pulmonary edema

- Person with history of COPD

- Asthma and Emphysema

- Pneumonia

What is halogens element

DochEvi [55]

The halogen elements are the six elements in Group 17 of the periodic table. Group 17 is the second column from the right in the periodic table and contains six elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (As), and tennessine (Ts). Astatine and tennessine are radioactive elements with very short half-lives and thus do not occur naturally.

Tanya is training a turtle for a turtle race. For every 1/6 of an hour that the turtle is crawling he can travel 1/24 of a mile.

frozen [14]

The rate at which Tanya's turtle travels is 0.25mi/hr

This question is from a topic in mathematics called Rate.

This is a ratio in which different terms in different units are compared against each other.

In this question, for every 1/6 of an hour, the turtle is crawling 1/24 of mile.

Data given;
