B, osmosis is the movement of water across a semi-permeable membrane according to the gradient of concentration. The water moves to were the concentration of  solute is higher, that way the solute concentration is equalized.

Fruit color in a particular plant is controlled by a set of three quantitative trait loci (i.e., QTLs or polygenes), that work i
tankabanditka [31]

Answer:

1/8

Explanation:

Given that the trihybrid parents have AaBbCc genotype for fruit color. The trait is a quantitative trait i.e. each dominant allele will have an additive effect on it. In this case, AaBbCc and AABBCC will not produce same fruit color because AaBbCc has only three loci contributing to the color while in AABBCC all the six loci are contributing to the color. For an offspring to be exactly similar to the AaBbCc parents it should have the same genotype of AaBbCc.

The probability of Aa to come from a cross between Aa and Aa is 2/4 or 1/2

The probability of Bb to come from a cross between Bb and Bb is 2/4 or 1/2

The probability of Cc to come from a cross between Cc and Cc is 2/4 or 1/2

So the collective probability of AaBbCc offspring from a cross between AaBbCc and AaBbCc parents would be=

1/2 * 1/2 * 1/2 = 1/8

Hence, assuming no effects of the environment, 1/8 of the offspring will have the same fruit color phenotype as the trihybrid parent.

What is the rock cycle and how does it explain the variations of rocks found on earth?
Licemer1 [7]
The rock cycle is a basic concept in geology that describes the time-consuming transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each of the types of rocks is altered or destroyed when it is forced out of its equilibrium conditions.

What are linked genes?
kumpel [21]

Answer:

Genes lying close to each other on chromosome

Explanation:

When genes lie close to each other on chromosome,  they are inherited together as an intact unit in meiosis cell division and such genes are termed as linked genes.During meiosis the genetic material (allele/genes) is exchanged between the homologous parent chromosome which causes  chromosome recombination and thus the formation of linkages These genes have high chances of recombination as they lie close to each other.
