Answer:
Active transport.
Explanation:
The kidney uses active transport to move these substances from the nephron to the renal vein because these substances did not moves from the nephron bowl to the renal vein through simple diffusion so for this purpose active transport is used in which energy is spent in order to move the substances from one region to another so we can say that kidney must use active transport to move reabsorbed substances from the nephron to the renal vein.

<span>How are the dark reactions that occur in plants dependent on the light reactions?
a.The chemical energy used in the dark reactions is produced in the light reactions.
Photosynthesis is divided into two parts.
1) Light - dependent reaction
2) Light - independent reaction
Light dependent reaction absorb energy from the sun to produce ATP and NADPH, these energies are used in the light-independent reaction. The ATP provides the energy, while the NADPH provides the electrons required to fix the carbon dioxide into carbohydrates.

Answer:
Option 2, Arousal
Explanation:
Reticular activating system (RAS) or the ascending arousal system consists of nuclei and tracts and is involved in the regulation of wakefulness, sleep aspects and arousal.
RAS is located in the mesopons and interacts with the basal forebrainand thalamocortical systems. It activates the cerebral cortex and thereby maintain the consiusness. The neurons located at the pontomesencephalic junctionparticipates in this activity of arousal.
Hence, option 2 is correct
Correct answer: D) Loss of insulation around vital organs
Fat is a nutrient should be to be taken in the diet but not in excess amount, it provides energy and help the body to absorb the vitamins.
It consists of a hydrocarbon chain and served to provide the structural and functional unit of the cell. The cell membrane is made up of a phospholipid bilayer, which consists of phosphate and glycerol.
The main function played by the fat inside the body include the transformation of energy and providing heat insulation to the body.
The adipose tissue of the body act as an insulator. As it contains fat molecule, and fat is a poor conductor of the heat, it traps the heat across the vital organ of the body such as heart, eyes etc. Due to the bad conductivity, fat molecule act as an insulator. It also acts as a cushion for most of the important organ of the body and protects them from damage and mechanical injury.
