Answer:
The correct answer will be option-B.
Explanation:
The plant tissues are composed of three types of cells: parenchyma, collenchyma and sclerenchyma.
The parenchyma and collenchyma remain alive at their maturity but sclerenchyma loses their protoplasm and become dead. These cells deposit lignin in their secondary walls and form hard tissues of the plant-like hard shell of a coconut. Sclerenchyma provides mechanical strength to the plant.
Thus, Option-B is the correct answer.

Explanation:
Answer:
C) autonomic nervous system (ANS) within the motor division
Explanation:
Autonomic nervous system is the involuntary portion of the nervous system.
The motor (efferent) portion of the autonomic nervous system is the major neural pathway for information transmission from the central nervous system to the involuntary effector organs like smooth muscles , cardiac muscles , exocrine glands etc.
Hence the autonomic system within the motor division doesn't appear to show some effects.
Hence option C) autonomic nervous system (ANS) within the motor division is the right answer.
scientific theory consists of one or more hypotheses that have been supported through repeated testing. Theories are one of the pinnacles of science and are widely accepted in the scientific community as being true. A theory must never be shown to be wrong; if it is, the theory is disproven. Theories can also evolve. This doesn’t mean the old theory was wrong. It just wasn’t complete.
The right answer is: Leptin
.
Leptin is a hormone closely linked to the regulation of energy consumption and expenditure: appetite, metabolism, and hunger.
A hormone is a protein with a messenger function. This means that once released into the bloodstream, she goes to another part of the body to transmit a message to specific receptors.
Leptin is manufactured in white adipocytes (adipose tissue) where triglycerides (fats) are stored and acts on the hypothalamus.
