A population of crabs live on a light-colored sandy beach. In this environment there is a population of birds that eat the crabs. One year, there is a volcanic eruption near the beach and dark volcanic ash covers the beach. The sand is now much darker than it used to be. Scientists studying the area are most likely to predict which outcome?
A.
Some of the light-colored crabs will try to change their body color to be darker and pass on those traits to their offspring.
B.
Some of the light-colored crabs will try to change their body color to be lighter and pass on those traits to their offspring.
C.

A dumping site in the small town of Love Canal, New York, was used for the disposal of industrial chemical wastes from 1970-1975. In 1980, the housing inspector noticed traces of toxic substances in the basement walls of the local schools and homes. The local hospital noticed that there were 25% higher numbers of birth defects during 1970-1980. The hospital then offered free genetic tests and found that 20% of the adult volunteers/residents of Love Canal contained genetic abnormalities. The exposure to those industrial chemical wastes must have been the cause the genetic abnormalities and higher birth defect incidence. Your Interpretation:
Answers
Answer:
There is no control group and variables were not addressed.
Explanation:
In the context, it is given that there is a dumping ground in a small town called Love Canal and harmful chemical waste of industries are dumped there. Lately, it is noticed that there were traces of the toxic substances on the walls of the schools and the hospitals. The hospitals also noticed that during the period of 1970 to 1980, there were increase in the number of the birth defects in the area. The people of the Love Canal has genetic abnormalities and the chemical waste is responsible for it.
Thus it can be concluded that there is a no such any control group in this case. The confounding variables like the comorbidities as well as the family history of the genetic defects were not addressed.

productivity. (4 points)
Answers
Answer:
Gross productivity refers to the amount of carbon fixed.
Explanation:
Gross productivity refers to the amount of carbon fixed during the process of photosynthesis by all producers such as plants and algae etc in the ecosystem. A large part of the energy that is produced in the process of photosynthesis is used by the plants in the metabolic processes of the producers such as respiration. The net productivity indicates that carbon dioxide plants that is used during the photosynthesis process substracted from carbon dioxide the plants releases during the process of respiration.

How is antibiotic resistance related to natural selection?
Answers
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

In many parts of the United States, homeowners use a significant portion of their energy budget to heat their home in the winter. It has been determined that lowering a thermostat by 3°F in the winter can reduce the energy costs by about 10 percent in many homes. An individual homeowner lowers their thermostat by 3 degrees exactly halfway through the billing period. For the month that the thermostat was lowered, the heating bill was $95. How much money did the family save in the month in which they lowered the thermostat setting halfway through the billing period?
Answers
Answer:
B. $5
Explanation:
$95/10 percent = 9.5
9.5/2 (because it is halfway through the billing period) = 4.75
4.75 rounded up to the nearest tenths place is 5.
A billing period is a duration of time that starts from the last closing date of the statement of the specific invoice. The billing amount fluctuates according to the usage of the services taken or used.
$5 will be saved by the family in a month when they lower the thermostat setting halfway through the billing period.
The amount can be estimated by:Given,
The heating bill when the thermostat was lowered = $95Reducing thermostats can reduce energy costs by = 10%10% of the total bill will be:
[tex]\dfrac {\$95}{10\%} = 9.5[/tex]
Divide the value by 2 because the thermostat was lowered in the middle of billing time.
[tex]\begin{aligned} \dfrac{9.5}{2} & = 4.5\\ &= \$ 5\end{aligned}[/tex]
Therefore, 5$ was saved by the family.

The inheritance of multiple phenotype genes that is the mother will have heterozygous as well as the father will have the heterozygous condition as well. The process is included in genetics and the genetics is related to it.
What is genetics ?It is defined as the study of genes and study of genes expression along with all the genetic factors associated with it.
The expression of the hair that is expressed in the progeny of the parents where the multiple expression is present can show incomplete dominance as well where none of the phenotype that is the alleles and the genes that are present in the parents will not express it in the child.
The process is also called as recombination where both the traits re expressed in the child and the characters both associated with the parents will express in the child.

Need help answering this Neurons are constantly firing on a regular basis in order to keep your body functioning. In your words, describe how a neuron utilizes a stimulus to create an action potential. (Be detailed)
Answers
Answer:
Action potentials are generated when information are sent down an axon through the neuron.
Explanation:
Neurons are nerve fibres which uses electrically charged chemicals to bring about an electrical change.
Action potentials can be defined as rapid changes in the membrane potential that spread rapidly along the nerve fiber membrane. Each action potential begins with a sudden change from the normal resting negative membrane potential to a positive potential and then ends with an almost equally rapid change back to the negative potential. The are three stages of action potential, these include:
--> Resting stage: This is the resting membrane potential before the action potential begins. The membrane is said to be 'polarized' during this stage.
--> Depolarisation stage: in this stage, the membrane suddenly becomes very permeable to sodium ions, allowing tremendous numbers of positively charged sodium ions to diffuse to the interior of the axon. That is, the normal polarised state, for example -90 millivolts, is immediately neutralised by the inflowing positively charged sodium ions, with the potential rising rapidly in the positive direction. This is called DEPOLARISATION.
--> Repolarisation stage: This occurs within a few seconds after the membrane becomes highly permeable to sodium ions, the sodium channels begin to close and the potassium channels open more than normal. Then, rapid diffusion of potassium ions to the exterior re- establishes the normal negative resting membrane potential. This is called REPOLARISATION of the membrane.
How many of the offspring are heterozygous?

The parent plants both have heterozygous (YG) genotypes, there will be 25% YY, 50% YG, and 25% GG offspring on average. These percentages are determined based on the fact that each of the 4 offspring boxes in a Punnett square is 25% (1 out of 4).
Assume that (B) is dominant and (b) is recessive: Bb mates with Bb
A. About 50% of the offspring will show the recessive trait
B. All the offspring will show the dominant trait
C. All the offspring will show the recessive trait
D. About 75% of the offspring will show the dominant trait
Answers
If B is dominant over b and Bb mates with Bb, about 75% of the offspring will show the dominant trait.
Looking at the cross:
Bb x Bb
BB Bb Bb bb
BB and Bb will show the dominant trait while only bb will show the recessive trait.
Thus, the chances of the offspring showing the dominant trait would be 3/4 or 75% while the chances of showing the recessive trait would be 1/4 or 25%

Answers
Answer:
According to Dr. David Coltman, the models of the genetic drift predict that the genetic diversity of the Mouflon should have been lost with time. However, the genetic diversity of the species has been maintained as natural selection is more essential to the evolutionary procedure than is considered generally. According to Dr. David Coltman, the models of the genetic drift predict that the genetic diversity of the Mouflon should have been lost with time.

The extreme conditions of the island are considered to have inhibited genetic drift, due to this premium advantage, the more genetically diverse mouflon on the island hold over their less genetically diverse counterparts.Answer:
Dr. David Coltman, an evolutionary geneticist at the University of Alberta, says that although the models of genetic drift predict the genetic diversity of the Mouflon should have been lost over time. The genetic diversity of the Mouflon has been maintained because "natural selection is more important to the evolutionary process than is commonly believed," according to Dr. Coltman. The extreme conditions of the island are thought to have prevented genetic drift because of the premium advantage the more genetically diverse mouflon on the island hold over their less genetically diverse cousins...
(If this is an of several small islands near the coast of Iran then cross breeding with male aboriginal Iranian Muzzistock is sufficient to maintain diversity but has shown to be detrimental to both species as evidenced in the fall in diversity of the Iranian Moui population.
Given many subspecies exists-- some of which were quasi-domesticated, it is possible the gene pool was replenished via shipwreck survivors from Iranian/Persian pirate or merchant shipwrecks --as the sheep were often kept as ocean going companions, milk, and, meat sources. It also depends on the islands location and if there was a land bridge 10-12-16,000 years ago during the last maximum glacial.)
