Answer:
move molecules into or out of cells of the body
Explanation:
Majorly, there are two types of transport used by living cells. These are; passive and active transport. Passive transport involves the movement of molecules down a concentration gradient without the need for energy (ATP) input. Example is DIFFUSION AND OSMOSIS.
On the other hand, active transport is a type of transport that moves molecules against a concentration gradient (low to high) with the aid of energy input (ATP). Example is sodium-pottasium proton pump.
Although there are obvious differences between these two processes (diffusion and active transport), but they both MOVE MOLECULES INTO OR OUT OF CELLS OF THE BODY.

(50pts) The evolution of the peppered moth over the last two hundred years has been studied in detail. Originally, the vast majority of peppered moths had light coloration. However, because of widespread pollution during the Industrial Revolution in England, the dark colored moths became much more common.
Question:
What specifically caused the shift in phenotype of the moths? Please explain in detail.
Answer:
The peppered moth is a temperate species of night-flying moth. Peppered moth evolution is an example of population genetics and natural selection and not artificial selection.
Explanation:
Answer:
The phenotype of the moth changed due to natural selection. During the Industrial Revolution, objects in England became a lot darker in color due to the settling of coal pollutants in the air. These light colored moths did not have good camouflage in this environment. Therefore, most of the light colored moths did not survive to reproduce. However, the dark colored moths had better camouflage, and were therefore more likely to survive and reproduce. This lead to a shift towards darker color moths, as they had a higher survival rate than the light colored moths.

How is antibiotic resistance related to natural selection?
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.

Which statement accurately describes how genetic information is transferred during meiosis?
Meiosis creates four daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates two daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates four daughter cells that have identical genetic information to the parent cells.
Meiosis creates two daughter cells that have identical genetic information to the parent cells.
Meiosis is the reductional division which creates four daughter cells that have identical genetic information to the parent cells. Thus, the correct option is C.
What is Meiosis?Meiosis is a special type of cell division which is also called as reductional division. This division takes place in the germ cells in sexually reproducing organisms which results into production of gametes, such as sperm or egg cells. Meiosis involves two rounds of division which ultimately result in the formation of four cells with only one copy of each chromosome or half genetic content.
Meiosis is divided into two divisions: Meiosis I and Meiosis II. In which, Meiosis II is similar to Mitosis and Meiosis I involves the reduction of genetic material to half.
Therefore, the correct option is C.

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?
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.

In one student's family, two of the children have curly hair, one child has wavy hair, and the fourth child has straight hair.
Which of these processes is responsible for the variety of hair texture in this family?
Answer:
A. sexual reproduction
Explanation:
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.

What explanation does science give about how the Mouflon found on an island in the Indian Ocean were able to maintain their genetic diversity under extraordinary circumstances?
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. However, the genetic diversity of the species has been maintained as natural selection is more essential to the evolutionary procedure than is considered generally. 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.)
