Answer:
Autocrine = Autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell.This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.
Juxtacrine = Juxtacrine signalling (or contact-dependent signalling) is a type of cell–cell or cell–extracellular matrix signalling in multicellular organisms that requires close contact.
Endocrine = Endocrine signaling occurs when endocrine cells release hormones that act on distant target cells in the body. Endocrine signaling can be distinguished from two other types of signaling: neural signaling and paracrine signaling. ... Neurons are connected to their target cells via synapses.
Paracrine = Paracrine signaling is a form of cell signaling or cell-to-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behaviour of those cells.
In any food chain, the percentage of energy passed from one level to another usually reduced by a factor of 10%.
In the food chain given in the question, we are told that the rabbit ate grass and the hawk ate the rabbit.
The grass carried out photosynthesis and obtained 100% energy from the sun. When the rabbit ate the grass, he obtained 10% of the energy from the grass, thus, the quantity of energy it gained from eating the grass is 10%, that is, 100/10 = 10%.
When the hawk ate the rabbit, it was only able to get 10% of the energy in the rabbit, thus, the quantity of the energy it gained is 1%, that is 10/10 = 1%.
Therefore, 1% of the energy stored by the grass is passed on to the hawk.
The answer is B. Stomata intakes carbon dioxide from the air and relapses cardon dioxide.
