Answer:

The pathway of oxygen from lungs to the body tissues is alveoli → red blood cells → blood vessels → tissues (option b).

Explanation:

The oxygen (O₂) required by the tissues comes from the air inspired by the respiratory system. The pathway of entry of O₂ to the body and tissues is:

O₂ from the air reaches the lungs.
In the pulmonary alveoli, gas exchange occurs, that is, O₂ passes into the blood capillaries and is captured by the red blood cells, while CO₂ is released and passes into the alveoli to be eliminated.
O₂ in the red blood cells travels through the blood vessels.
The tissues receive the O₂ and a second gaseous exchange occurs at the tissue level, as they release CO₂ that will be carried to the alveoli.

Tissue oxygenation depends on the integrity of the respiratory and circulatory systems.

<em> The other options do not show the correct order in which the oxygen travels from the alveoli to the tissues.</em>

List name three characteristics of scientists that are important to their work but also found in nonscience

zimovet [89]

The right answer is research reading and writing.

The research includes a collection of data, information, and facts for the advancement of knowledge.

Reading is undoubtedly an entertainment, but it is also a precious help to learn to express oneself and to think.

Reading is an awakening of the soul and the heart. Enjoyment of thought and feeling.

Writing is a graphic expression of language, it is a process that is currently used to immobilize, to fix the articulated language, fleeting in essence.

andriy [413]

Answer:

The correct answer is B. the two strands of DNA must separate.

Explanation:

DNA is a double-stranded structure. The two strands are joined together by the formation of hydrogen bonds between complementary nucleotides. So before the replication takes place these two strands must be separated.

The separation of DNA strand is accomplished by the action of a helicase enzyme which breaks the hydrogen bond between complementary nucleotides and separated the two DNA strands.

After separation, the DNA polymerase binds to separated DNA and replicating the DNA. So the right answer is B.

Which of the following results when a person’s hand is near an open flame?

Ede4ka [16]

Given what we know, we can confirm that when a person's hand is near an open flame, the brain is required to integrate incoming and outgoing information. Option C is correct.

<h3>What happens when a person's hand is near a flame?</h3>

We can say that the information from the heat being generated by the flame is received by sensory neurons in the person's hand. This information generates a pain response which is integrated as incoming information in the brain, which then produces a motor response to move the hand away from the flame, as an outgoing signal.

Therefore, we can confirm that when a person's hand is near an open flame, the brain is required to integrate incoming and outgoing information. Option C is correct.
