I’m pretty sure it’s a. sorry if i’m wrong <3
<h2>Answer:</h2>
The correct options are A,D and E which are plant trees, irrigate dry field and remove dead leaves respectively.
<h3>Explanation:</h3>
- Wind erosion is the creation of big dust storm by small air rolls containing small particles like tillage and small dust particles.
- Plant trees stops the formation of the small air rolls y providing physical resistance.
- Remove dead leaves stops the tillage to contribute in dust storm.
- Irrigate dry field decreases dust in air.
Answer:
Chromosomes will not align at the equator of the cell, and subsequently will not separate to opposite poles.
Explanation:
Mitosis is a cellular division that results in daughter cells with identical copies of the genetic material as the parent cell. Mitosis is characterized by different stages viz: Prophase, Metaphase, Anaphase, and Telophase. The centromere is a very important part of the cell during division as it produces microtubules that grows out and bind to the kinetochore of each chromosome, hence, aligning them at the CELL PLATE (cell equator) and subsequently pulls them apart to opposite poles. This alignment and pulling apart occurs during METAPHASE and ANAPHASE respectively.
Mutation is any change that occurs in the nuceleotide sequence of the genetic material (DNA). If a change/mutation occurs leading to a defective or non-functional centromere, the centromere will no longer be able to produce microtubules that will bind to the kinetochores of each chromosome. Therefore, the chromosomes will be unable to align at the equator/middle of the cell and most importantly, inability to separate to opposite poles, which is the main point of Mitosis.
Savannas can be found anywhere but must be located in a tropical climate to thrive.
The U.S.A. has a very moderate climate, and for the most part is the same overall. Thus, a savanna wouldn't be able to exist in the U.S.A without the tropical climate, which means all 12 months have temperatures around 64 degrees Fahrenheit, and there are only two seasons: wet and dry.
As opposed to the U.S.A's Moderate Springs, Blazing summers, chilly falls, and cold winters (may fluctuate depending on the state), a savanna wouldn't be able to thrive.
Your answer is D: they exist only in the tropics.
~Hope this helps!
It is false that all of the waters of the Earth form the biosphere.
