This binding blocks the electron transport system in the mitochondria where ATP manufacture occurs
Answer:
B.During photosynthesis, plants take in carbon dioxide from the air.
Explanation:
A.During photosynthesis, plant roots take in water from soil. - water is part of the hydrosphere, not the atmosphere.
B.During photosynthesis, plants take in carbon dioxide from the air. - this is true, the plant - a living thing and part of the biosphere - takes carbon dioxide from the atmosphere to use during photosynthesis.
C.Through photosynthesis, energy stored in plants is released into the air. - this is false, plants release oxygen into the atmosphere as part of photosynthesis
, which synthesises glucose. It does not release energy.
D.Through photosynthesis, energy stored in plants is transferred to humans who eat them. - this is true, but does not involve the atmosphere (air in the environment)
<h2>Answer:</h2>
Option B, the diver will hear the sound first.
<h2>Explanation:</h2>
Sound need a medium to travel from one place to another, the medium where atoms are more closely packed together, the better will be speed of sound. That is why sound won’t travel in a vacuum because there are no particles to bump together to transmit the vibration.
- In air, the particles are generally far from each other so they travel further before they bump into one another.
- In water, the particles are much closer together, and they can quickly transmit vibration energy from one particle to the next. This means that the sound wave travels over four times faster than it would in air.
<span>The right answer is D. males have only one copy of the X chromosome.
</span>Hemophilia is a rare hereditary bleeding disorder disease. The blood of hemophiliacs does not coagulate normally. Bleeding is not more important, but without treatment, they can be more frequent and last longer than normal. Hence the importance of good monitoring and good treatment.
<span>The 2 types of hemophilia A and B are recessive and X-linked, but a third of hemophilia correspond to a de novo mutation. It is observed that a man who wears the X is always affected by the disease (because he has only one X chromosome in its genome) whereas the woman is only a carrier (she has two X chromosomes, so it can carry a safe X and a mutated X without being attempted by the disease but can transmit it to her descendants). This must be taken into account for genetic counseling.</span>
