Answer:

D. The substances utilized in response to light are produced in the terminal bud.

Explanation:

The substances which are produced in the apical meristem are known as the auxins.  are responsible for solar tracking in plants. are a powerful growth hormone that are produced naturally by plants. They are mainly found in shoot and root tips and promote cell division, stem and root growth. They also drastically affect plant orientation by allowing cell division to one side of the plant in response to sunlight and gravity. That response to sunlight by the hormone is know as phototropism where the plant would move towards the source of light which promote its growth. The movement of auxins due to gravity it is known as geotropism where the hormones moves to one side of the root in response to gravity.

Answer:

In mammals, oxygen is carried through the red blood cells called hemoglobin. The reason is that the oxygen is very important for the cell for releasing energy. This energy is used by the cell in different processes.

2) These adaptations are adapted by the organisms in order to perform different functions. In slow twitch skeletal muscles having high number of mitochondria because it requires more energy while fast twitch skeletal muscles contains less amount of mitochondria due to low requirements of energy. These characteristics are adapted according to the performance of the body parts.

Why does transcription occur in the nucleus and not in the cytoplasm in eukaryotes?
pav-90 [236]
Transcription is the process by which the DNA molecule makes an RNA molecule using enzyme RNA polymerase and other proteins. The mRNA is then used to generate proteins by a process called translation which occurs in the cytoplasm. Transcription occurs in the nucleus because DNA cannot leave the nucleus.
