Describe the process of seed germination

Biology

Slav-nsk [51]3 years ago

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.

Answer:

Explanation:

1. Describe two effects of insecticide use on the forest ecosystem other than the intended reduction of moths to protect the trees.  

1. Insecticides when sprayed on a certain areas or spots can be blown by the wind to other areas or flow with rain water into nearby streams or local water bodies or seep through the soil into ground water. This is called indirect application or secondary poisoning,

2. Insecticides can affect the food chain because they reduce the biomass of primary consumers and there is is less food available to secondary consumers which eat poisoned plants or prey those who have been exposed to pesticides.

Insecticides can travel great distances through the environment and they can also flow with rain water into streams so fish can be directly or indirectly impacted by pesticides. The phenomenon of nutrient enrichment of aquatic bodies is known as eutrophication, which deteriorate the water quality leading to death of fish. Some long-term exposures cause abnormalities or mutations in developing fish larvae, while acute exposure can cause immediate fish die-offs. The liver, kidney, brain and gills of exposed fish are extremely vulnerable to chemical exposure.

denis-greek [22]

Answer: specialized service

Explanation:

An economy experiencing high interest rates will have to reduce investment generally, BECAUSE higher rates increase the BORROWING and demands that ONLY investments with prospect of HIGHER RETURNS (i.e PROFITABLE) should be considered.

Thus, all options are profitable EXCEPT specialized services, as they would be considered a luxury (too costly)
