Hello! Thanks for posting this on brainly. Based on the passage i say A. Is the answer. Tell me if im correct please.
The volume of the cube of unknown substance is 
. The length of one side of the cube is 9 cm
<u>Explanation:</u>
As per the formula of mass and density, Mass / Density equals to volume. Therefore as the mass of the cube was given to be 81 g and the density of the cube is known to be 3.0 g/
,, to help Bill find out the volume. It is the ratio of mass and density and can be calculated as
As it is a cube, the volume is product of length, breadth, and height. Here, all sides are same as it is the cube.
I'd say your answer is,
C. the attraction and bonding of ions with equal opposite charges.
<span>From the proportions of phenotypes in the offspring. If Genes would be equal you would get 1/4 A, 1/4 B and 1/2 AB; but you often get 1/4 A and 3/4 B. </span>I hope that this is the answer that you were looking for and it has helped you.
Answer:
In humans, genetic variations are caused because humans reproduce by a sexual life cycle which is termed as meiosis. In such a life cycle, the offspring receives half the chromosomes from the mother and half from the father. Crossing over and random assortment of chromosomes are two phenomenons which occur during meiosis. Due to these two phenomenons, genetic variations are caused.
During crossing over, the exchange of DNA segments between the homologous chromosomes takes place which brings about the genetic variations.
