Answer:
DNA Sequencing.
Explanation:
In field of Biotechnology, we use an instrument known as "Gel Electrophoresis" in this instrument, different sized DNA Fragments are placed. After that, Electricity is applied due to which Negatively charged DNA fragments move towards positive charge through Gel Medium. Small sized DNA Fragments reach destiny before large fragments.
This is an application of Electrophoresis.
The correct answer is: dependent variable.
There are two main variables in an experiment: the independent and dependent variable.
The experimenter changes the independent variable and that has the influence on dependent variable. So, the effect on the dependent variable is tested (observed and recorded).
Answer:
they would provide nutrients for new living things to feed on.
Explanation:
Fish eating birds would need important in the formation of a new community of living things because as they feed on these fishes on the rocks, they would also be eliminating wastes. The wastes that are being eliminated would serve as a source of nutrient on the Island. With time there would be enough nutrients for plants to tart growing
Below are the questions:
A) A hovering mosquito is hit by a raindrop that is 45 times as massive and falling at 8.9m/s , a typical raindrop speed. How fast is the raindrop, with the attached mosquito, falling immediately afterward if the collision is perfectly inelastic?
<span>B) Because a raindrop is "soft" and deformable, the collision duration is a relatively long 8.0 ms. What is the mosquito's average acceleration, in g's, during the collision? The peak acceleration is roughly twice the value you found, but the mosquito's rigid exoskeleton allows it to survive accelerations of this magnitude. In contrast, humans cannot survive an acceleration of more than about 10 g.

Below are the answers:
a. <span>MU = (M + m)V; where M = 45 m, U = 8.9 m/s, find V = ?. V = (45/46)*8.9 = 8.7 m/s
</span>
b. <span>F = m dV/dT = m 8.7/8E-3 = m 1.0875E+03; so G = 1.0875E+03/9.8 = 111 G's.</span>
Answer:
Explanation:
Endocrine cells in the pancreas are referred to as Islets of Langerhan. There are two major types; Beta cell that produce insulin and alpha cells that produce glucagon.
They are identified when viewed under slides based on their colour reactions with histological dyes. Tinctorial techniques that can be used to identify them under microscope includes; Mallory-Heidenhain azan trichrome, chromium hematoxylin and phloxine, aldehyde fuchsin, and silver impregnation methods.
Islets of Langerhan cells make up minority of the cell. Majority of them are for exocrine functions.
