The urinary system removes liquid waste, while the excretory system removes solid waste.
Explanation:
Answer:
In the process of genetic engineering, the mixing of genes may occur between host genome and vector.
Explanation:
Genetic engineering is a process that applies biotechnology to the field of genetics, producing desirable alterations in the genome of an organism by introducing genes or fragments of genetic material from another organism.
The organism that is intended to produce the change or alteration is called the host organism, while the genetic information extracted from another organism to be introduced to the host is called the vector.
<u>The production of genetically modified organisms by genetic engineering responds to manipulation where the genes of a host are mixed with those of a vector</u>.
Answer:
option D
Explanation:
This is to test for the genotype of an organism that shows the dominant phenotype for a particular trait trait. To perform a testcross in determining the genotype of a plant, a true breeding pink flowering plant is usually utilized.
<h3><u>Answer and explanation;</u></h3>
- This can be done by<u> DNA sequencing which is the process of determining the accurate order of nucleotides within a DNA molecule</u>.
- By doing a DNA sequencing for the two sequences of DNA from the two species it will help compare the number of random mutations which have occurred in a molecular clock in the two species - that is, seeing how different the sequences are.
- This will make it possible to infer how long ago the species diverged.
Species A: GTTGAGCTAGTATGGACC
Species B: GATAAGCTAGTAAGGTCA
These species differ in 5 nucleotides.
This number should be multiplied by the rate of mutations; that is;
5 × 15 million years =75 million years.
