Scientists use biotechnology to create all of the following except waste products. The correct answer is D.
Answer:
D. If all of the offspring are short-tailed, the unknown individual is the homozygous dominant genotype.
Explanation:
The short tail phenotype is completely dominant over the long tail phenotype. When a short tailed salamander with unknown genotype is crossed with a homozygous recessive long tailed salamander, the cross is called testcross. Lets assume that the allele "S" gives "short tail" phenotype while the allele "s" gives "long tail" phenotype.
If the "short tailed salamander" with unknown genotype is homozygous dominant (SS), the process of the testcross will express only dominant trait (cross 1). On the other hand, if the "short tailed salamander" with unknown genotype is heterozygous dominant (Ss), segregation of alleles during gamete formation would form two types of gametes (cross 2). The 50% progeny would express the "long tail" phenotype while rest 50% will express the "short tail" phenotype.
Life forms that depend on remineralize shells and skeletons will be harmed by ocean chemistry, as would species that are acid-sensitive and organisms higher in the food chain that eat these sensitive animals.
<h3>An organism is what, then?</h3>
An organism is a collection of molecules working together to form an more or less permanent together that demonstrates the characteristics of life. Definitions in dictionaries frequently use general terms like "any biological entity, such as a plant or animal reproduction."
<h3>What two kinds of organisms are there?</h3>
Prokaryotic and eukaryotic organisms are the two primary categories. These type the cells that form the organism are the basis for this differentiation. Prokaryotic cells have a very basic, rudimentary structure without a nucleus. Additionally, membrane-bound organelles are absent.

Answer:
a variety of genes are involved in the control of cell growth and division. the cell replicates itself in an organized, step by step fashion known as the cell cycle.
Explanation:
tight regulation of this process ensures a dividing cell's DNA is copied properly, any errors in the DNA are repaired and each daughter cell receives a full set of chromosomes.
I strongly think it's c mainly because it;s the only one that talks about everyone being the same and not evolving like they should.
