Answer:
Facilitated diffusion
Answer:
HERE IS YOUR ANSWER
Explanation:
Facilitated diffusion is the diffusion process used for those substances that cannot cross the lipid bilayer due to their size and/or polarity (Figure 3.18). A common example of facilitated diffusion is the movement of glucose into the cell, where it is used to make ATP

In which column on the chart below would the information below best fit for a mode of reproduction, CANNOT REPRODUCE WITHOUT A HOST?
Answer:
B. Virus.
Explanation:
Hello.
In this case, since bacteria (A.) reproduce via asexual reproduction via mitosis and the animal (D.) and vegetal (C.) cells could reproduce via sexual or asexual reproduction depending on the organism, they do not need a host to start the replication of the DNA and therefore reproduce. In such a way, it is widely known that viruses need a host that facilitates the replication of their DNA or RNA (depending on the virus) since they only have their genetic information but they do not have neither the RNA nor the DNA polymerase that favor such process, that is why they need a host.
Best regards.

A runner has a speed of 25 m/s. They see the finish line and speed up to 30 m/s. This happens in 5 seconds. If the runner has a mass of 75 kg, with what force did the runner cross the finish line? Show all work to receive full credit.
I know the answer is 75N but I don't know how to get 75N
Given parameters:
Initial velocity = 25m/s
Final velocity = 30m/s
Time = 5m/s
Mass of runner = 75kg
Unknown:
Force to finish the race = ?
Solution:
Force is defined as a pull or push on a body. According to Newton's first law, we can mathematically express force as the product of mass and acceleration;
Force = mass x acceleration
But we know that acceleration is the change in velocity with time, so;
Acceleration = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]
So, force;
Force = mass x [tex]\frac{Final velocity - Initial velocity}{time}[/tex]
Input the parameters and solve;
Force = 75 x [tex]\frac{30 -25}{5}[/tex] = 75N
The runner crosses the line with a force of 75N

What is photosynthesis?
Photosynthesis is the process by which plants
use energy from sunlight to produce food.
Without photosynthesis, life on Earth simply would not be possible.
Without photosynthesis, we would not be able to breathe
because it gives off the oxygen that we breathe into our lungs.
If a person's blood pressure is too high or too low, how might the other organ systems in their body be affected?
Answer:
When blood pressure is too high, organs and blood vessels can be damaged. High blood pressure can even cause rupture of a blood vessel and lead to bleeding or other complications. When blood pressure is too low, not enough blood reaches all parts of the body.

Which phrase best describes the independent variable in an experiment?
Answer:
In a scientific experiment, the dependent variable is the variable that is being tested and then measured. The answer referenced in D, the variable that is manipulated, is referring to the independent variable.
Explanation:
The independent variable is the thing you are changing in your experiment (eg.the temperature).

A genetic trait is inherited via the Y chromosome such that for a father with the trait, his male offspring have a 25% chance of inheriting it but his female offspring cannot inherit it. Suppose that in a certain population, 40% of offspring are male and offspring genders are independent events. For a father with the trait who has two offspring, what is the probability that the older offspring has the trait and the younger offspring does not?
Answer:
0.09
Explanation:
let us define these events as
O = older
Y = younger
Prob(O) = 40% offspring x 25% chance of inheritance
= 0.4x0.25
= 0.1
P(Y') = 40% offspring x (1-25%) +(1-40%)x1
= 0.4x0.75 + 0.6x1
= 0.3+0.6
= 0.9 this is the probability of having the trait.
Probability that older offspring has trait but younger does not have it
Prob(O n Y') = prob(O) x Prob(Y')
= 0.1x0.9
= 0.09

Striated muscles are cylindrical, unbranched, multinucleate and voluntary. These muscles are attached to bones hence, called as skeletal muscles. These muscles are under control of the conscious will.
Smooth muscles are spindle-shaped, uninucleate, unbranched and involuntary. These muscles are not under control of the conscious will.
Cardiac muscle cells are cylindrical, branched, uninucleate and involuntary. These muscles are not under control of the conscious will.

The Siamese cat breed has a light colored body and dark colored head, tail, and feet, all of which are called points. The Burmese cat breed has a dark colored body and points that are almost the same color as the body. Crossing Siamese with Burmese can produce the Tonkinese cat breed, which has coat and point color that is intermediate to the Siamese and Burmese parents.
In all three breeds, a temperature sensitive enzyme is responsible for the dark coloration of the points. However, it is active only at the extremes of the body where it is coolest. Select the statements that are true regarding the evidence of incomplete dominance and incomplete penetrance in these breeds.
a. Intermediate coat color in Tonkinese demonstrates incomplete dominance.
b. Development of points in Tonkinese demonstrates incomplete penetrance.
c. Light coat color in Siamese demonstrates incomplete penetrance.
d. Darker color at the extremes of the body in Tonkinese demonstrates incomplete dominance.
Answer:
Correct answer is A and B.
Explanation:
Because the Tonkinese breed has a coat that is intermediate to the coat color of the Siamese and Burmese, we can say that this demonstrates incomplete dominance which means that the dominant allele does not have the ability to completely mute the recessive allele in the phenotype.
This is also true because of the development points on the coat of the Tonkinese breed.
So the correct answer is A and B.
I hope this answer helps.

Answer:
reproduction

generation
Explanation:
Natural selection is differential reproduction among individuals, in a population due to differences in phenotypes, which are said to be adaptive.
Individuals with the adaptive phenotype have a reproductive advantage (increased reproductive fitness); therefore, they contribute a disproportionately high number of progeny to the next genotype.
The adaptive genotype and the underlying mutation will increase in frequency in the generation over time.
In rats, gene B produces black coat color if the genotype is B-, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D-, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. A third independently assorting gene involved in determination of coat color in rats is the C gene. At this locus, the genotype C- permits expression of pigment from genes B and D. The cc genotype, however, prevents expression of coat color and results in albino rats. For each of the following crosses, determine the expected phenotypes and their ratio in progeny:Part ABbDDCc x BbDdCcExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).Part BBBDdcc x BbddCcExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).Part CbbDDCc x BBddCcExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).Part DBbDdCC x BbDdCCExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).
