Answer:
C. Slide A, plant cells; Slide B, animal cells
Explanation:
The slide A has some organelles that are unique to plant cells, and are mostly found in plant cells. Organelles such as a cell wall and chloroplasts are unique features of plant cells. They are normally absent in animal cells.
Therefore, slide A, which has these cell organelles can be rightly labelled as "plant cells", while side B, which has these organelles missing, can be labelled as "animal cells".
Since all of the three beetle species posses the protein, we can use it to determine their relations. We can study the sequence of the amino acids that make the protein and the 3D structure of the protein. The more differences there are in amino acid sequences and the structure of the protein, the species are more distantly related because they have diverged a long time ago and their genes that produce that protein have undergone many changes over time.
Answer:
The correct answer is E. Lactate and NAD+
Explanation:
Fermentation occurs in anaerobic condition and in humans, most of the energy is provided by aerobic respiration but when the body needs a lot of energy in a very quick time like in sprinting then muscles use lactic acid fermentation to gain energy.
After the consumption of all stored ATP during intense work, our body starts lactic acid fermentation to gain ATP. In lactic acid fermentation, the pyruvate molecule that was produced during glycolysis is converted into lactate molecule. In this process, NADH is oxidized to NAD+.
Therefore in lactic acid fermentation lactate and NAD+ are produced. So the correct answer is E.
The correct answer is option D
the pineal gland releases melatonin into the bloodstream
In the exocrine system the organ releases certain substance other than hormone while in the endocrine system , the organs releases hormones.
In option D, melatonin is a hormone released by pineal gland and thus it is an endocrine function
