omeli [17]

Answer:

The correct answer is option A) "cause iron in ocean water and terrestrial rocks to rust (oxidize)".

Explanation:

During ancient times, the reproduction success of plants and cyanobacterias led to the accumulation of oxygen gas in the atmosphere. One early consequence of this accumulation was the oxidation of the iron in ocean water and terrestrial rocks. This phenomenon is the cause of banded iron formations, which formed in seawater and sank to the ocean bed.

asambeis [7]

Answer:

oxygen gas

red blood cells

platelets

Explanation:

» <u>Concepts</u>

Your blood is composed of four main things: <u>red blood cells</u> (that transport <u>oxygen</u>), <u>white blood cells</u>, <u>platelets</u>, and <u>plasma</u>. Red blood cells transports oxygen and takes out CO2, white blood cells fight bacteria and viruses, and platelets clot together to stop bleeding.

<u>Bile</u> is a fluid that is produced by the liver and stored in the gallbladder, so it's not a main component of blood.

How does extracellular glucose inhibit transcription of the lac operon?
Genrish500 [490]

The extracellular glucose inhibit transcription of the lac operon (D) by reducing the levels of intracellular cAMP.

Lac operon is the assembly of various genes that are involved in the uptake and metabolism of lactose of E. coli or any other bacteria. It consists of a regulator gene, promoter gene, operator and structural gene. Structural genes are three: z, y and a. Each codes for a different enzyme.

cAMP is the cyclic Adenosine Monophosphate. It is produced by the bacteria when there are low levels of glucose in it. Hence it is also named as hunger signals. Therefore, cAMP is responsible for activating the operon to produce lactose.

What causes changes in air pressure in the atmosphere
harina [27]

Answer:

Air pressure is caused by the weight of the air molecules above

Explanation:

Air pressure is caused by the weight of the air molecules above. Even tiny air molecules have some weight, and the huge numbers of air molecules that make up the layers of our atmosphere collectively have a great deal of weight, which presses down on whatever is below.

A student decided to investigate the effect of pH on the activity of the enzyme lipase , five different test tubes are set up ,e
castortr0y [4]

Answer:

the pH

Explanation:

The condition that should not be kept the same in each of the five test tubes is the pH.

Since <u>the aim of the experiment is to investigate the effect of pH on the activity of the lipase enzyme</u>, the pH is, therefore, the <em>independent variable</em>. Thus, it must be controlled or varied in all the test tubes in order to see its effect on the activity of the enzyme, which, in this case, would be the dependent variable.
