Answer:

E. 3, 6, 7, 4, 5, 8, 1, 2

Explanation:

Systemic circulation is the circulatory pathway which is involved in the transport of the oxygenated blood to the body when pumped by the heart through arteries, capillaries and then back to the heart.

In the given question, the order of vessels in the systemic circulation has been asked which begins with the entry of the deoxygenated blood to the heart.

1. The deoxygenated blood enters the blood from vena cava to the right ventricle.

2. From the right ventricle, the blood enters the right atrium which pumps the de-oxygenated blood to the lungs through an artery called the pulmonary artery.

3. In the lungs, the blood becomes oxygen rich and is returned to the left atrium through the pulmonary vein.

4. The blood then enters the left atrium which is then pumped to the body through the main artery called the aorta.

This completes the systemic circulation and thus, Option-E is correct.

Ceratium fusus is a protist that is found primarily in coastal waters, especially around the coast of the United Kingdom. These

A chemical defense mechanism is called bioluminescence.

As mentioned in the reaction, Ceratium fusus undergoes a special chemical reaction at night which helps them defend themselves from predators. During this reaction, light is produced inside a living organism. However, this type of reaction does not produce heat although it does produce light.

<h3>What is bioluminescence used for?</h3>

The most well-known purpose of bioluminescence is to defend the organism against attacks by predators. This is because the light confuses or frightens predators.

Besides confusing the predator, the light can also alert large predators to approach the location of the organism, in this way this large predator will eat the predator that is threatening the organism which in our question, is Ceratium fusus.

Many marine organisms use the phenomenon of bioluminescence for their defense, in particular marine invertebrates, vertebrates, certain micro-organisms as well as certain fish and fungi.

Hence concluded that the bioluminescence characteristic of Ceratium fusus is being described.

High salinity and drought conditions may both cause Arabidopsis plants to become:
Sever21 [200]

Answer:

Option-D

Explanation:

Arabidopsis is a model organism plant used by scientists all over the world to study the genetic mutations and the effect of various factors on the plant.

In the given case, it has been mentioned that the plants were growing in the drought or no water conditions and the high salinity or high salt conditions.

The high salt condition interferes with the absorption of other nutrients whereas, in less water condition, the loss of water from the plant not equals the absorption as a result of which the plant dehydrates.

Thus, Option-D is correct.

Describe the process by which cells produce the , and include the location
Masteriza [31]

Answer:

Photosynthesis

Explanation:

is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive. Oh yes, we need the food as well!
