<h3><u>Answer;</u></h3>
The above statement is <u>false</u>
<h3><u>Explanation</u>;</h3>
- Rocks have different porosity and permeability characteristics, which means that water does not move around the same way in all rocks below ground.
- Permeability greater than 250 mD are considered very good, while permeability less than 1 mD are considered poor.
- Low porosity normally results in low permeability, but high porosity does not necessarily imply high permeability. It is possible to have a highly porous rock with little or no interconnections between pores.
Answer:
The phenomenon that explains the trend seen in the data is that the mosquitoes' evolution has led them to develop resistance to the compound.
Explanation:
This is a very common factor that we can see in insects. The effect of DDT on the species will have different levels of impact. One is going to be more vulnerable to the compound that the rest. However, after many times of exposition to the compound, a few survivors will develop resistance to the compound and their offspring is going to inherit that resistance. Making them increase the resistance over time.
Answer:
a structure composed of several proteins that associate with the centromere region of a chromosome and that can bind to spindle microtubules
Explanation:
Kinetochores have vvery important role in the cell division-mitosis.
During the metaphase of mitosis, spindle fibers attach to kinetochores. Some of the microtubules bind to kinetochore (kinetochore microtubules) while other don’t: they connect with the microtubules from the opposite pole, stabilizing the spindle.
During the anaphase, kinetochore microtubules pull chromosomes toward poles, helping the sister chromatids separate from each other.
