First let's take a look at the two squares close to the electron transport chain. As you can see, the two boxes are connected, which means there is some type of "conversion" occuring. Oxygen goes in and water comes out. (In other words, upper square = oxygen, lower square = water).
Now, the box that is far from the rest corresponds to the mithocondrial matrix of a mithocondrion, since we're talking about .
The two boxes connected to the ATP synthase are aso connected to each other, one going towards the ATP synthase and the other going out. Now, we just have to guide ourselves with logic. It's called "ATP synthase", which means the product will be ATP. So, ADP goes in and ATP comes out.

I think some ellimination would do good to answer this question. First of all, salmon contains a reasonable amount of B12 and iron and has high amounts of protein, of course. So options B., D. and E. are incorrect.
Nor salmon nor garlic butter contain fiber, so option A. is also incorrect.
Answer:
C.

The Krebs cycle, the electron transport chain and respiration (aerobic) are closely related, because in anaerobic respiration we obtain oxygen, which functions as an electron acceptor in the electron transport chain, which produces NAD+ that is later used in the Krebs cycle to produce NADH and FADH2 that are used as electron carryiers in the ETC.
Answer:
C.

Answer: Option A) Parathyroid glands
Explanation:
The Parathyroid gland located in the neck region helps in the secretion of an hormone called Parathormone.
This hormone helps to raise the levels of calcium ions in the body, by preventing the loss of calcium ions through urine, and also preventing excess deposit of calcium ions in the bone, thus regulating bone density.
The correct answer is (b.) an increase in the width of the stem. The increase in the width of the stem could be referred to as the secondary growth of the stem. Whereas the primary growth is the upward growth of the plant.
Answer:
Henslow organised his herbarium to emphasize variation within species and determine the limits between species. He was a religious man who believed the orthodoxy of the day that species were stable and did not evolve. ... When Darwin took his famous trip on the HMS Beagle in 1831, his place was arranged by Henslow
Here are few of the things that scientists think may happen as the temperature rises. Some of them are already happening:
Glaciers melting - Many glaciers are already melting and shrinking throughout the world. If the temperature increases they will continue to melt. This will cause animals that rely on glaciers such as polar bears and other species to become extinct.
Ocean levels will rise - As the glaciers melt, the ocean levels will rise. This could cause flooding in cities located near the coast.
Migration of animals - Animals will migrate to cooler spots as their old habitats get too warm. This could upset the food chain and put some species in danger of extinction.
Extreme weather - Some scientists think that warming will fuel more powerful hurricanes as well as more droughts and flooding in different areas of the world.
Change in ecosystems - cold weather biomes such as the tundra will shrink, while desserts will continue to expand.
