The answer is D) unlimited flow of water into or out of the cell for #9.
For #10, the answer is C) endocytosis and exocytosis.
Answer:
B) The completely-plated phenotype is controlled by a dominant allele of a single gene.
Explanation:
<em>The results from the breeding experiment showed that the completely-plated phenotype is controlled by a dominant allele of a single gene because it followed Mendelian pattern of inheritance.</em>
According to Mendel, in a dominant/recessive gene situation, the recessive gene do not manifest physically in F1 generation and at F2, the phenotypic ratio of dominant to recessive gene is usually 3:1.
For example, assuming the completely-plated gene is represented by P and the alternate form (low-plated) by p.
At F1: PP x pp
Progeny: all Pp, completely-plated stickleback in appearance.
At F2: Pp x Pp
Progeny: PP, Pp, Pp, and pp
3/4 of the progeny have completely-plated appearance while 1/4 have low-plated appearance. The ratio of completely-plated to low-plated is 3:1.
The correct option is B.
The physical property that makes iron useful for cooking and baking food is : ( A ) They have low specific heat
<h3>Property of Iron </h3>
Irons are used for making cooking pots and pans because they can easily retain heat energy once absorbed, i.e even after the heat source have been removed, this property means that irons have a lower specific heat.
Hence we can conclude that the physical property that makes iron useful for cooking and baking food is that it has a low specific heat.

write the procedure in the passive voice (reporting fashion )
Answer:
C. Can be made up of a combination of different elements
Explanation:
The definition of a chemical compound is: "A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. Two atoms of the same element bonded in a molecule do not form a chemical compound."
