Answer:

The correct answer is mesosphere.

Explanation:

The atmosphere exhibits five distinct layers, which are determined by the modifications in temperature that take place with the upsurging altitude. These are troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Of the mentioned layers, the mesosphere, that is, the layer present above the stratosphere is considered as the coldest layer of the atmosphere. The coldest portions of the atmosphere are situated in this layer and can reach up to -90 degree Celsius.

Answer:

Tofu and soy oil come from soy bean plants that are grown on farms. Many farmers grow soy beans as cash crops that they can send to places such as tofu processing plants. Soybean plants are legumes. Legumes have bacteria on nodules which are on the roots of the plant. The bacteria on the nodules takes nitrogen from the air and fixes it into the soil, so that other plants that require nitrogen can use it as well.

This nitrogen cycle that was breifly discussed above is used in what farmers call a crop rotation. Farmers use soybeans and other legumes in roatations with grass crops such as corn or wheat. Grass crops are unable to take their own nitrogen from the air so they either need the nitrogen in the soil that the legumes provide for them in a crop rotation or they need a chemical fertilizer containing nitrogen. Many farmers choose to use both. Most farmers use a two or four year rotation on their fields. In a two year rotation a farmer will alternate a year of a legume such as soybeans and a year of a grass crop such as corn. In a four year rotation a farmer will alternate back and forth between legumes and grass crops just as in a two year rotation, but instead he will use four differnt crops. For example, a farmer may plant a rotation of soybeans, corn, alfalfa (a legume), then wheat (a grass).

In which phase of meiosis will sister chromatids separate and move to opposite end of the cell
yawa3891 [41]
The Telophase 2 is the fourth step or process during Meiosis (cell division). During Telophase 2, a nuclear envelope forms around each set of new chromosomes. In this stage, cytokinesis occurs, which is responsible for producing four daughter cells each with a haploid set of chromosomes. During the crossing-over phase some chromosomes are observed to have segments that have recombined with the original parent chromosomes.  
<span>
When the phase is over, the two cells are now finally separated and their nuclear membranes are fully formed causing the meiosis cell division to be completed.</span>

Explain why rabbits are more destructive in Australia than in the U.S.?
Dmitrij [34]
There are no natural predators of rabbits in Australia, so they are able to reproduce at an alarming rate unharmed. In the US however, there are foxes and other animals that prey on rabbits, which helps keep the rabbit population lower.
