Biology
1 answer:
ddd [48]2 years ago

By leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent ____________________.
shusha [124]

Answer:

Soil erosion.

Explanation:

No-till plowing can be defined as a farming method or technique which typically involves planting crops (seedlings) without tilling the soil rather the farmer would only open a narrow or very shallow trench of sufficient depth and width to cover up the seedlings. Thus, the no-till plowing makes crop residues to be left on the soil and by extension preventing soil erosion through the absorption of water by the crop residues.

Hence, by leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent soil erosion.

Additionally, the water retention ability of no-till plowing is usually a boon to farmers because it slows down evaporation and serves as a good protection for drought-stricken environments.

How does the possible impact of a chromosomal mutation that occurs?
Papessa [141]
  If the mutation occurs during meiosis, the mutation will be incorporated into a gamete. If that gamete is the one that eventually fuses with another gamete (i.e. if it's the sperm that fertilizes the egg), that mutation will be passed on to the offspring. As all the offspring's cells are the result of the first two gametes, all the organism's cells will have that mutation. Obviously this can have dire consequences for the offspring, if the mutation is harmful.

Because they often survive at extreme temperatures, _______ are thought you have been the first organisms on the early earth
zimovet [89]

Answer:

Extremophiles

Explanation:

Extremophiles are organisms that have been discovered on Earth that survive in environments that were once thought not to be able to sustain life. These extreme environments include intense heat, highly acidic environments, extreme pressure and extreme cold. Different organisms have developed varying ways of adapting to these environments, but most scientists agree that it is unlikely that life on Earth originated under such extremes.
