Answer:
The correct answer will be option-E
Explanation:
The autonomic nervous system or ANS activity in the brain is mainly controlled and regulated by the hypothalamus structure. The autonomic centres of the hypothalamus control the hormonal secretion adrenal medulla like adrenaline and norepinephrine.
The secretion of the hypothalamus controls the activity of the vasomotor center which help maintain the blood pressure.
Thus, option-hypothalamus is the correct answer.
Answer:
1.) neurilemma (option f)
2.) nissil bodies (chromatiophillic substance)
3.) neurofibrilis ( option g)
4.) myelin ( option e)
5.) dendrite ( option d)
6.) collateral ( option c)
7.) astrocytes (option a)
8.) axon ( option b)
9.) Unipolar neuron (option i)
Explanation:
The neurological terms described above are different parts of a nerve cell or neurones. The nerve cells are the basic Structural units of the nervous system. They are highly specialised for transmitting electric impulses. They can also be grouped according to the number of processes they possess, for example, the UNIPOLAR NEURONS( those with one process only). Each neuron, however, is composed of the same basic parts which include:
--> The CELL BODY: they may be angular or oval in shape with a large nucleus and dense granulated cytoplasm. In the cytoplasm, rough Endoplasmic reticulum which contains CHROMATIOPHILLIC SUBSTANCE (nissil bodies) and Golgi apparatus are also seen.Network of threadlike structures known as neurofibrilis are also seen within the cell body and extending into axon.
--> DENDRONS: these are one or more extensions which branches to form many fine dendrites. The DENDRONS carry nerve impulses( action potential) that their dendrites receive to the cell body.
--> AXON: this is a long process which branches at it's free end to end in synaptic knobs. It carries electric impulses away from the cell body. Most times, a substance of Schwann cell known as MYELIN SHEATH which is composed of lipoprotein insulates axons and increases impulse speed.
A major study has shed new light on the dim layer of the ocean called the "twilight zone" -- where mysterious processes affect the ocean's ability to absorb and store carbon dioxide accumulating in our atmosphere.
Answer:
Estimated size is 1600
Explanation:
Given data:
Size of lake is 250 hectares
Total number of trout who netted is 400
Total number of trout in next week is 200
Total number of trout having fin clip 50
estimation population size is estimated by mark rupture as follow
Estimated population size 
Estimated size
Estimated size is 1600
Survival would be correct
