Water in ocean currents can descend when it becomes colder and saltier thanthe surrounding water. If water descends to the bottom of the ocean, then other
water must rise to the top. What causes water to rise to the top of the ocean?*
It is forced upward by underwater mountain ranges
It cools down and dissolves additional salt
It is brought upward by organisms that live in the ocean
It becomes less dense than the surrounding water

Answers

Answer 1
Answer:

Answer: D it becomes less dense than the surrounding water

Explanation: when the water becomes colder and saltier it becomes more dense so the less dense water rises to the top.

Sand for beaches comes from rocks in the area that are weathered down, andtheir sediment is deposited in the area beaches. The beaches are then eroded,
and the sediment is moved away from the beaches. If rocks stopped weathering,
how would the beach change?

Answers

Answer:

Beaches would shrink until they were no longer there because the sediment is pulled away from the shores by the tide and there would be no new rock sediment to replace the old rock sediment.

Which process enables the use of resources repeatedly​

Answers

Answer:

Reversible process

Explanation:

Reversible process is the process in which the reactants and the products both are used. They both are produced also. We can consume either the product or the reactant. So, if we need a resource to be produced repeatedly, we should put it in a reversible process.

What is the relationship between the strength of your heart and aerobic respiration efficiency

Answers


The relationship between the strength of your heart and aerobic respiration efficiency is this one:
If your heart is stronger, it pumps more oxygen and glucose in the blood to cells - increasing the efficiency of aerobic respiration

The synthesis of an amino acid follows this pathway: precursor A → intermediate B → amino acid C. Each reaction is catalyzed by a different enzyme. This metabolic pathway is controlled by feedback inhibition with amino acid C inhibiting the conversion of precursor A to intermediate B. Amino acid C acts as a _____ of the first enzyme in the pathway.

Answers

Answer:

The synthesis of an amino acid follows this pathway: precursor A → intermediate B → amino acid C. Each reaction is catalyzed by a different enzyme. This metabolic pathway is controlled by feedback inhibition with amino acid C inhibiting the conversion of precursor A to intermediate B. Amino acid C acts as a noncompetitive inhibitor of the first enzyme in the pathway.

Explanation:

A no-competitive inhibitor reduces the activity of an enzyme by binding at its active site although it has already bound to the corresponding substrate

Final answer:

Amino acid C acts as a noncompetitive inhibitor, regulating its own production via feedback inhibition. This is a common mechanism used in metabolic pathways to maintain balance.

Explanation:

In the described pathway, amino acid C regulates its own production by inhibiting the first step of the pathway. This is an example of a regulatory mechanism called feedback inhibition. Essentially, when there's plenty of amino acid C present, it will bind to the first enzyme in the pathway, preventing its action and thus stopping more of amino acid C from being produced. So, in this scenario, amino acid C is acting as a noncompetitive inhibitor of the first enzyme in the pathway.

A train accelerates at a rate of 2.5 km/hr/sec. During the acceleration period, its velocity changes by 55 km/hr. Choose the exact time of the train's acceleration.A. 1,200 s

B. 22 hr

C. 22 s

D. 0.045 s

Answers

Using the formula :
v = u + at
a = accelaration = 2.5 km/hour^2
v = final velocity = 55 km / hour
u = initial velocity (in this case u=0)
t = time

hence,
v = 0 + at
v = at
55 km /hour = 2.5 km/hour^2 * t
t = 55 km /hour / 2.5 km/hour^2 
t = 22 hours

Answer:

22 hr
