Basically the seed contains 2 parts, the testa, which is the seed coat that protects the seed and cotelydon, which is the inside of the seed, containing the radical and plumle.
for seed to germinate, we need 3 basic conditions,
warmth, it is the suitable temperature for seed germination, it can influence the activity of enzymes. providing a optimum temperature
water, to soften down the testa so that the shoot can break out from the testa
and oxygen, for aerobic respiration
.
If these conditions are absent, the seed may be in the state of dormancy. where is won't germinate until it meets the suitable conduction.
after that, the enzyme will digest the nutrient inside the seed and provide amino acid, which is necessary to seed germination. and meanwhile the aerobic respiration provides energy, so that the plumlecan shoot out, and be the shoot of the plant.
and then until it grows leaves, it'll start to complete photosynthesis, instead of using the nutrients inside the cotelydon.
The answer to this is Gonads.

Answer:
The tilt of earth's rotation axis stays the same as it orbits the sun.
Explanation:
The axis of the Earth is an imaginary line around which the Earth is known to orbit. The axis of the earth is known to tilt at an angle of 66 and a half degrees. The tilt of the axis of the Earth remains the same and it does nor change as the earth orbits around the sun. The orbiting of the Earth around its axis causes day and night to occur on the planet Earth. The rotation of the Earth around its axis is slowing with time.
If the earth's atmosphere gets bigger, every creatures and humans die by pressure
