Lisa [10]3 years ago

The Hardy – Weinberg principle has seven conditions that should occur in the evolution of the population. One is when mutation does not happen. Two, is when natural selection is not occurring. Three, if the population is infinitely large. Four, if all the members of the population produce offspring.  Five, sexual intercourse is random. Six, the population will produce the same number of offspring. And lastly, the population does not migrate from one place into the other. The thing that would disrupt the genetic equilibrium is the mutation.

A nurse fails to communicate a change in the client's condition to the physician. which element related to proving malpractice h
Brums [2.3K]
I would say that this would be an example of negligence with the nurse failing to report in a change of the patient's condition to the doctor because it is the duty of the nurse to not only find out changes in the patient's condition but also to share it with the main person who can do something about it or make a decision on how to deal with a different condition.

A researcher claims that only a portion of the light energy captured by green plants is available for growth and repair. Which o
gtnhenbr [62]

Answer:

This question lacks options, the options are:

A) Light-capturing pigment molecules in green plants absorb red, blue and violet light but reflect green light.

B) The energy of a photon of light is proportional to its frequency and inversely proportional to its wavelength

C) As light energy is converted to chemical energy by metabolic processes, some of the energy is lost as heat

D) Captured energy is stored in the molecular bonds of organic molecules, including simple sugars and starch

The answer is:

As light energy is converted to chemical energy by metabolic processes, some of the energy is lost as heat.

Explanation:

Green plants are capable of synthesizing their own food via a process called photosynthesis. The photosynthetic process uses light energy from the sun to form organic chemicals necessary for the growth and repair of plant tissues.

Plants are able to capture light energy from the sun using their chlorophyll pigment. Out of this captured energy, only a portion of the light energy captured by green plants is available for growth and repair. This is because as light energy is converted to chemical energy (stored in chemical bonds) by metabolic processes, some of the energy is lost as heat.

Which of the following is TRUE? Species on Earth today are just a fraction of all species that ever lived. The number of species
Orlov [11]

Answer:

Until recent history,extinctions have always happened gradually and on a small scale.

Explanation:

Extinction occur when environmental factors like natural disaster,habitat fragmentation,over exploitation,global change don't favor the survival of species thus gradually leads to extinction of species.

Some times human activity becomes the major problem for extinction.More over,poor reproduction,decline in population number and genetic inbreeding also leads to extinction.

99% of all species that exist on earth become disappeared.

Evolution leas to speciation which leas to formation of new species but species become extinct when they are unable to survive against competition.

There are 100 cats in a population that follows hardy-weinberg conditions. 4 cats display a recessive white coat color. how many
mr Goodwill [35]

We know that Hardy-Weinberg conditions include the following equations:


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


where p+q=1


And where p = dominant, and q = recessive; this means that p^{2} is equal to the homozygous dominant, 2pq is the heterozygous, and q^{2} is the homozygous recessive .


So we have 100 total cats, with 4 having the recessive white coat color. That means we have a ratio of \frac{4}{100} or 0.04. Let that equal our q^{2} value.


So when we solve for q, we get:


q^{2}=0.04

q=\sqrt{0.04} =0.2


Now that we have our q value, we can use the other equation to find p:


p+q=1


p+0.2=1


p=0.8


So then we can solve for our heterozygous population:


2pq=2(0.8)(0.2)=0.32


This is the ratio of the population. So we then multiply this number by 100 to get the number of cats that are heterozygous:


0.32*100=32cats


So now we know that there are 32 heterozygous cats in the population.
