Answer:
Traits Are Inherited from a Parent through Transmission of DNA. Drosophila chromosome
sorry if this is not the right answer
Answer: When genes found on different chromosomes, said to be not linked.
When genes seen close together on the same chromosomes said to be linked.
Explanation:
(a)
According to Mendel’s law of independent assortment, when genes located more than 50 map units and found on different chromosomes as far apart on the same chromosome so they divide independently and obviously said as not linked.
(b)
It is found that when genes located and seen tightly close together on the same chromosome, known to called as Linked which means that alleles or genes look close together on the same chromosome can be inherited afterwards as a unit frequently than not. For instance, when two genes are linked and become tightly close together by using data from genetic crosses lead to calculate recombination frequency as well.
Similarly, when we finding recombination frequencies for more than one gene pairs, can make linkage maps among them that finally show the relative distance between them.
A nonconformity exists between sedimentary rocks and metamorphic or igneous rocks when the sedimentary rock lies above and was deposited on the pre-existing and eroded metamorphic or igneous rock
C) all cells divide to form new cells
Antarctic fish species requires an adaptation to cold environment. Living at cold temperature environment would demand certain biological responses such as cutaneous respiration, enlarged blood vessels, and producing greater amounts of fat. Most of these fat are composed of higher phospolipid levels which are primarily due to phosphatidylethanolamine. This phospolipid is responsible for destabilizing cell membranes and make it more fluid thereby allowing unrestricted blood flow. The fatty acid composition of the membrane lipid is important for membrane fluidity, this is mainly attributed to unsaturated fatty acids which are responsible for decreasing the order of membrane lipids thereby decreasing viscosity. At extremely low temperatures, organisms with low concentration of unsaturated fatty acids would freeze cell membranes. That's why antarctic fishes have higher levels of unsaturated fatty acids.
