Photosynthesis: This is a main activity permed by most plant cells where carbon dioxide, water, and sunlight are used to make glucose and oxygen. This process is especially important for all living organisms since glucose is a main source of cellular energy.
Cellular respiration: This activity takes glucose and breaks it down so that cellular energy can be made. If cellular respiration is not performed by any cell, they will have a hard time living and thriving.
Mitosis: This activity is where a parent cell divides into two identical daughter cells. It is important for the cell to have identical copies of every organelle and genetic information to complete this process.
Cleaning, Storing, and Building: These, and many more, are some of the other activities performed by a plant cell that help maintain homeostasis. The cells organelles are constantly cleaning up waste, storing necessary nutrients and genetic information away, and building new proteins that will help other
Answer:
B
Explanation:
blood only absorbs end products of digested food .
Studying animals in the wild is considered somewhat experimentally out of control because of several reasons.
<u>Explanation:</u>
Study of wild animals can be done using several methods but none will be as effective as studying captivated animals. Using stationary cameras is a method to observe animals in the wild. The stationary nature of the camera makes it necessary for the animals to appear within the field of the camera.
This is difficult in places of low animal density. In addition to that placing camera at a longer distance to watch a larger area decreases the resolution of the images. When it comes to shallow water systems, the field imagery used to track the aquatic species frequently gets affected by issues like sun flicker.
Unmanned aerial vehicles can also be used to track and study animals in the wild. This is good alternative but filming through dense canopies or turbid water is a limitation. Bio loggers can also be used for animal tracking but it is limited by weight since it has to be carried by animals.
Both are myelinated, however, the oligodendrocyte myelinates up to 40 axons and the schwann cells myelinates a section of one axon.
Answer:
NAD+ act both as coenzyme as well as electron acceptor compound and get reduced to NADH by accepting electron.
Explanation:
NAD+ act as co enzyme of various biological catalyst such as malate dehydrogenase, isocitrate dehydrogenase etc.
NAD+ can act as co enzyme only in its oxidized form but not in its reduced form called NADH.
Many reaction needs NAD+ to occur such as conversion of glyceraldehyde 3 phosphate to 1,3 bisphosphoglycerate, malate to oxaloacetate.
That"s why NAD+/NADH ratio is kept very high because if this ratio bychance get low then it will hamper the normal redox potential of NAD+/NADH.As a result many biochemical reaction will not take place.
