<span>The genotype is
required for you to use a punnet square. In the construction of a punnet's
square, the genotypes of both parents are required. In the three by three
square, the first column shows the genetic representation of one parent and the
first row shows the genotype of the other parent. The two are combined, and
they yield a genetic combination of both parents, giving all the possible
outcomes of the offspring's genotypes. Using the punnet's square, you can be
able to identify the percentage of the offspring that will be heterozygous or
homozygous.</span>
Answer:
Natural enzymes called restriction enzymes Can cut and copy DNA at specific sites. Then the DNA fragments can be separated by the process of gel electrophoresis.
Explanation:
Restriction enzymes recognize restriction sites in the DNA and bind to them. Then they will cut the two DNA strands and give two separate sequences of DNA that can bind to another piece of DNA if the sequence match.
Gel electrophoresis will separate the different cut fragments of DNA by size and charge. The scientists put the DNA fragments in indentations in the gel, then the gel is placed into a gel box with a buffer solution, a negative electrode near the indentations, and a positive electrode on the bottom. When the electric current goes through the gel, the DNA fragments will start to descend towards the positive electrode since the DNA has a negative charge. As a result, DNA strands will descend faster through the gel's pores than the larger strands. The final step is to dye the gel to see the different bands with fragments of various DNA sizes.
First stage of photosynthesis in which light energy from the sun is captured and changed into chemical energy that is stored in ATP and NADPH; also known as the light-dependent reactions. ... The splitting of a water molecule to replace electrons used during the light reactions; splitting by light
Answer: The correct answer is Diffusion.
The molecules of carbon dioxide enter the oceans through the process of diffusion into the surface of sea water and dissolve by a physio-chemical process. The factors affecting the amount of carbon dioxide diffusion includes wind, concentration of carbon dioxide, temperature of the water etc. The carbon dioxide which diffuses into the oceans reacts with water forming carbonic acid, carbonate and bicarbonate ions. The gaseous form of carbon dioxide in atmosphere is converted to non-gaseous form reduces the carbon dioxide pressure in the water and promotes more diffusion from the atmosphere.
