Which structure is highlighted?
Answer:
i believe is pulmonary arterioles
Explanation:
The structure which is highlighted is the pulmonary arterioles.
What do you mean by Structure?A structure may be defined as any systematic representation of any object or thing in a visible manner.
Pulmonary arterioles are the terminal branches of the mammalian pulmonary arterial tree. These arterioles do not consist of smooth muscles. The specific role of the pulmonary arteries is to carry blood that's low in oxygen and high in carbon dioxide waste to the pulmonary capillaries of the lungs, where this exchange takes place.
Therefore, the structure which is highlighted is the pulmonary arterioles.

A car accelerates from rest to a speed of 24 m/s in 8 seconds. What is the car's average acceleration?
A 16 m/s2
B. 24 m/s2
C 3 m/s2
D. 192 m/s2
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
We know that,
[tex]a = \dfrac{v - u}{t} [/tex]where,
a = avg acceleration v = final velocity = 24 m/su = initial velocity = 0 m/st = time taken = 8 secso, let's find avg acceleration :
[tex]a = \dfrac{24 - 0}{8} [/tex][tex]a = \dfrac{24}{8} [/tex][tex]a = 3 \: \: m {s}^{ - 2} [/tex]hence, correct choice is C
If a car accelerates from rest to a speed of 24 m/s in 8 seconds, then the car's average acceleration would be 3 meters / second², therefore the correct answer is option C.
What is acceleration?The rate of change of the velocity with respect to time is known as the acceleration of the object.
As given in the problem if a car accelerates from rest to a speed of 24 m/s in 8 seconds, then we have to find out what is the car's average acceleration,
The average acceleration of the car = final velocity - initial velocity/time
= 24 -0 /8
= 3 meters / second²
Thus, the correct answer is option C.

3. Human skin cells divide at a higher rate than neurons (nerve cells). Hypothesize why this may be.
Answer:
the skin cells prevent germs from coming in our bodies
Explanation:
Skin temperature varies more than core temperature since it is more exposed to the outside environment. As the body attempts to lower your internal temperature, the skin will cool due to factors like sweat and evaporation, for example.
What are the reason that skin temperature is high?Because of exposure to the environment and changes in blood circulation brought on mostly by thermoregulatory responses, skin temperature varies throughout the body.
The temperature of the proximal section of the limbs and the trunk fluctuate less (3° to 4 °C) than the fingers and toes, which can vary by up to 30 °C.
Therefore, Because skin cells keep bacteria from entering our bodies. It must proliferate more quickly, since skin cells can be removed extremely readily.

16. Why does a plant cell need a larger vacuole?
Answer:
The plant has the largest vacuole than animal cells because in plant cells the larger central vacuole performs two functions, one is to store water and the other is to help the plant remain upright. In animal cells, vacuoles are smaller but more in number because they do not require vacuole for rigidity or pressure.

Sexual reproduction lead to variation of species explain why variation is an advantage of species such as enearld dove
I WILL GIVE BRAINLIEST Explain why variation is an advantage for a species such as the common emerald dove
Answer:
Variation refers to the differences between members of the same species. Having variation within a species means that if the environment changes there may be individuals within the species more able to withstand the change and survive. There is usually extensive genetic variation within a population of organisms or a species.
The advantages of sexual reproduction:
it produces variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease or change in environment is less likely to affect all the individuals in a population
Humans can speed up natural selection through selective breeding, which can increase food productions.
Variation refers to the differences between members of the same species.
What is Variation?variation within a species means that if the environment changes there may be individuals within the species more able to withstand the change and survive. There is usually extensive genetic variation within a population of organisms or a species.
Individual or population differences due to genetic variation, including changes in DNA. Human genetic diversity, including genetic variations within and between human groups.
