Answer:
can occur instantaneously through formation of polyploid offspring.
Explanation:
In Sympatric speciation, species are not geographically isolated but reproductively isolated from each other as two varying types of species is observed to have emerged from one original. Take for example, in Fruit Flies where each species have different food choices, making each one to feed on separate fruits.
"SYMPATHETIC SPECIATION do occur instantaneously through formation of polyploid offspring (it has double the normal amount of chromosomes)". And it's most likely take place due to natural selection. It relies on the process of disruptive selection acting against hybrids.
Answer:
Farming affects biodiversity as it needs space and chemicals.
Explanation:
Farming requires space, so it firstly contributes in the habitat loss of many plants and animals species that were already present there. Then seeds are sown to grow the desired
I would say the growth, the repair, and the reproduction.
The correct answer is - D. Volcanic mountains form on land but not on the ocean floor.
The volcanic mountains are a result of the volcanic activity. They appear at places where there's a plate boundary, most often in the places where there's a subduction zone.
These mountains can only form on the land or above the surface of the water, but not on the ocean floor. The reason why they can not form on the ocean floor is because the magma is cooling down almost instantly, and it is pretty much impossible for a volcanic mountain to form. On the other hand, they can be found totally submerged in water, but those are volcanic mountains that have formed on land, got eroded, and sunk bellow the water.
Seed technology is the science dealing with the methods of improving physical and genetical characteristics of seed. It involves such activities as variety development, evolution and release of varieties, seed production, seed processing, seed certification and storage. Thus seed technology is interdisciplinary science which includes broad range of subjects. It also includes seed quality control, seed marketing, seed distribution and research on above aspects of seed.
