Answers

Answer:

Because different telescopes are used to study and observe different types of objects in space.

Explanation:

They need many different types of telescopes to look at space because each telescope shows them different things. Light comes in wavelengths from short to long. Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study. And it also depends on the telescope itself.

Answers

The primary function of cellular respiration is to break down food molecules and generate ATP.

What is cellular respiration?

Cellular respiration is the process by which living organisms obtain energy in form of ATP by breaking down food molecules in their cells.

Cellular respiration occurs in all living organisms because energy is required for their daily metabolic activities.

Therefore, the primary function of cellular respiration is to break down food molecules and generate ATP.

PUMPS BLOOD

It pumps blood allowing the distribution of nutrients to all parts of the body

HEART

noun

The heart is the organ in circulatory system that pumps blood throughout the body by the help of the atriums and ventricles that supply oxygen, nutrients to the body and take out deoxygenated blood away to the lungs.

ATRIUMS AND VENTRICLES

The right atrium is the upper chamber of the heart that receives deoxygenated blood from the vena cava and pumps it into the right ventricle which sends the blood out to the lungs so that it become oxygenated.

Left ventricle the thickest of all the heart's chambers is responsible for the pumping of oxygenated blood to tissues all throughout the body.

This is the correct sequence of events of the cardiac cycle.

Answers

Given what we know we can confirm that the correct sequence of events for the cardiac cycle is atrial systole, ventricular systole, atrial diastole and  ventricular diastole.

What is the cardiac cycle?

The cardiac cycle is what we define as the cycle in which the heart beats. This cycle begins with the systole of both the atria and the ventricles, in which they contract, first the atria, then the ventricle. This is to pump blood into the next part of the circulatory tract. This is followed by the diastole of each cavity, in which they fill with blood once more.

Therefore, we can confirm that the correct sequence of events for the cardiac cycle is atrial systole, ventricular systole, atrial diastole, and ventricular diastole.

Meaning of cardiac cycle

Cardiac cycle is a measure of the heart performance start form a single beat to the beginning of the next heartbeat. it occurs in four phases which starts with the Ventricular filling phase and ends with the isovolumetric relaxation.

Hence we can conclude that the correct sequence of events of cardiac cycle is as listed above.

6. How did natural selection work in the red-eye frog egg hatching?
7. What was the explanation regarding the phenotypic plasticity of the red-eye frog eggs?

Answers

We can confirm that natural selection resulted in the coloration of the red-eye frog due to its higher chance of survival with this change in pigment.

Why would this color help the frog survive?

Bright pigments are a common defense mechanism in nature. Organisms that are poisonous often evolve bright coloration as a warning to predators. Over time, natural selection ensures that the organisms who've successfully incorporated this pigmentation have much higher survival rates and therefore the species entirely evolves into possessing this trait, as was the case with the red-eye frog.

Therefore, we can confirm that natural selection resulted in the bright pigmentation of the red-eye frog because of the much higher survival rate that this adaptation afforded the organism.

C. Individuals with thicker fur had a survival advantage in the cold, allowing these individuals to reproduce moe often and create more offspring.

Explanation:

Natural selection means the process of changing the adapting the new environment. Based on the given data one can conclude that the individual with thicker fur had a survival advantage in the cold environment.

Why natural selection occurs?

Natural selection takes place due to 3 underlying reasons:

Reproduction

Heredity

Variation in fitness of organisms.

Due to these reasons, natural selection can leads to speciation.

As the individual are living in cold environment, they need to adapt the change in environment. So, individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offsprings.

Thus, option C is correct.

Proteins of smaller molecular size may be reabsorbed from the glomerular filtrate by the specific transport process of __________.

Answers

Proteins of smaller molecular size may be reabsorbed from the glomerular filtrate by the specific transport process of endocytosis.

What do you mean by Glomerular filtrate?

The Glomerular filtrate may be defined as the liquid in the lumen of the Bowman's capsule of the nephron that has been purified from the capillaries of the glomerulus.  

The small molecular size proteins may be absorbed from the glomerular filtrate by receptor-mediated endocytosis. Then moved into the endosomes, and finally to the lysosomes for the degradation.

Therefore, proteins of smaller molecular size may be reabsorbed from the glomerular filtrate by the specific transport process of endocytosis.
