<u>Answer</u>:
1. C. Process one describes cloning and process two describe artificial selection
Through cloning a genetically identical individual is obtained from a single individual. Through artificial selection a hybrid between two individuals with desirable traits is obtained.
2. C. Polygenic
A trait that has a continuous variation has a polygenic inheritance pattern as it is controlled by multiple genes.
3. C. The BW mice would have black and white patches
Codominant genes will produce an individual with an intermediate phenotype as both alleles are simultaneously expressed in the heterozygote.
4. D. Polygenic
Polygenic inheritance occurs when two or more genes determine a trait that has a continuous variation. Each gene has a small effect, but all together have a cumulative effect. Examples of such patterns are height, sking color, eye color, weight etc.
There are no choices but examples of biotic factors are trees, mosses, ferns, fungi, mammals, birds, reptiles, worms, plants, and lichens.
Answer:
option D is incorrect
Explanation:
the sedimentation coefficient is measured in Svedberg units named after the scientist Theodore Svedberg. the shape of the particle being measured in the ultracentrifuge is one of the factors that determines the sedimentation coefficient. the values are usually not additive as the sedimentation coefficient is based on the rate at which a particle sediments in an ultracentrifuge and not on the size. for example, the sedimentation coefficient of eukaryotic ribosome is 80S but is made up of the 60S large subunit and the 40S small subunit.
Answer:
No atoms are created or destroyed in chemical reactions.
Explanation:
Matter cannot be created or destroyed. When two reactants contact each other, a chemical reaction occurs which breaks the bonds between atoms and rearranges them, forming new bonds which transform them into the product. The same amount of atoms exists before and after the reaction.
From what I understood, the answer is 2a (:
