Polystyrene is a good insulator as it has small air bubbles trapped inside of it. This means heat energy cannot flow through them therefore it is an effective material for keeping honeybees warm in the winter. Hope this helps :)
Answer:
Explanation:
Exons can be shuffled independently known as exon shuffling. It can be done in various ways, leading to infinite number of combinations to discover new and meaningful coding sequences hence various proteins. Due to exon shuffling, evolution need not occur only by the slow accumulation of point mutations but might also move ahead by “quantum leaps” with new proteins appearing in a single generation.
Answer:
The human skeleton performs six major functions: support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation

Answer:
(Twisted leaves)
The mutant allele is dominant to its corresponding wild-type allele
(Forked leaves)
The mutant allele is dominant to its corresponding wild-type allele
(pale leaves)
The mutant allele is neither dominant nor completely recessive to its corresponding wild-type allele

I have attached picture which explains phenomenon it self.
Answer:
The part of the microscope that is used to make small adjustments in the image of an object is the fine adjustment.
Explanation:
In the optical microscope, the fine adjustment knob allows precise focusing of the sample being studied. This means making minimal adjustments in order to better observe the microscopic image.
After the initial focusing with the coarse adjustment knob, with the fine adjustment it is possible to highlight the details that require more attention, as well as the refringency of the sample, if it exists.
The other options are not correct because:
<em> A. </em><em><u>Eyepiece</u></em><em> is the lens that receives the image from the objective lens, that has contact with the eyes of the observer.</em>
<em> C. </em><em><u>Coarse Adjustment </u></em><em>is the rough magnification, used for the initial approximation of the image.</em>
<em> D. </em><em><u>Objective lens</u></em><em> enlarges and defines the image of the sample on the slide.</em>
