Answer:
All of the above.
Explanation:
For the study of protected animal species, biologists should follow some steps. Those animals which are in protective condition are placed in the natural environment so that they can live their natural life and can reproduce easily. So, for inspecting the animals in their area, the biologists should move on to the area where they live. Along with this, they have to apply for permission to enter into the habitat of the animals because they are protected. We know that entering into a protected area is not possible without permission.
The correct answer is the immune system, more specifically, the thymus gland. The thymus gland, while it produces hormones like thymosin, it is more closely related to the immune system rather than the endocrine system. This is because lymphocytes that go into the thymus gland mature into T lymphocytes that can either be a helper T cell or a cytotoxic T cell, depending on the stimulus.
The answer is cross-pollination.
Answer:
The statistics given has shown that night-migrating birds are driven by autonomous circadian clocks which is made possible by sunset cues. This timekeeping that is the autonomous circadian clocks system is probably the key factor in the overall control of nocturnal songbird migration.
Answer:
The correct answer would be d chloroplasts, which can be found in leaf cells of trees.
Chloroplasts are double-membrane cell organelle usually present in leaf cells of a plant.
They are the site of photosynthesis in plants by which plants convert solar energy into sugars. Oxygen is released as the byproduct of the process.
Light reaction of the photosynthesis takes place in the thylakoid membrane. It produces ATP and NADPH and releases oxygen.
Dark reaction takes place in the stroma of the chloroplast in which ATP and NADPH are used to fix carbon (obtained from carbon dioxide) into sugars (glucose).
The overall reaction is:
6CO₂ + 6H₂O + solar energy → C₆H₁₂O₆ + 6O₂
