Answer:
anterior pituitary gland.
Explanation:
The growth hormone from the anterior pituitary gland is responsible for the growth of bones and soft tissues during the growing age. The hormone stimulates lipolysis to increase the release of fatty acids for ATP production as required for growth.
It also reduces the uptake of glucose from the blood to ensure fuel availability for growth. In the absence of growth hormone or its hypo-secretion from anterior pituitary results in stunted growth. The individual is short in stature than the other individuals of the same age group. The condition is called dwarfism.
Answer:
cell wall, chloroplast, and one big vacuole
Explanation:
Cell wall - exterior to the cell membrane is a rigid cell wall made up of cellulose. It is freely permeable to water and solutes but prevents the cell from bursting
Chloroplast- contains green pigment, chlorophyll, which traps light used in photosynthesis.
Vacuole- filled with sap which contains sugar, salts and waste products and enclosed by tonoplast. Acts as a store for sugars and salts. Maintains the shape of the cell.
Capacity of cell nucleus is in the range of 10^-15
Answer:
Fossils generally helps in relative dating of rocks.
The Trilobites are considered the oldest in this rock sequence when we apply the principle of superposition of strata.
The principle states that "in an undeformed/undisturbed sequence of rock, the oldest is always at the bottom while the youngest is on top" .
This principle therefore explains why the Trilobites at the base are considered the oldest.
