First answer. Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote).
Second answer. Crossing results in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive)
Third answer. Crossing results in 100% (homozygous recessive).
hope this helps!!!!!!!!!!

The correct option is D.<span>
Craig Venter contributed significantly to
science and humanity by inventing a synthetic cell. He accomplished this by
constructing the genome of a bacterium and by incorporating it into a
cell. The cell was made by joining together the genome of a pathogen from small stretches of DNA that are synthesized in the laboratory. The genome created was then inserted into an empty cytoplasm of a related bacterium. The pathogen use is called mycoplasma mycoides, it usually infect goats.</span>The cell is the first synthetic life form in the world and it open the
way for new types of research.
Answer:
Viruses are tinier than bacteria. In fact, the largest virus is smaller than the smallest bacterium. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host.
Explanation:
Aerial roots perform a number of functions unlike the usual functions performed by roots stationed on soils. They help with air exchange, propagation, stability and nourishment. In many cases, aerial roots can be removed without harm to the plant
Answer:Increase in ambient global temperatures.
Recyling energy to be used again
Regulation of oxygen and carbon dioxide levels
An increase of erosion and siltation along waterways
Explanation:
Conservational biologists think about the preservation of ecosystem by maintaining the environment in a human control way.
Increase in ambient global temperatures.: The humans must prevent the increase in global temperature worldwide by preventing the rise of greenhouse gases which can lead to global warming worldwide.
Recyling energy to be used again: The sources of energy like wood, waste water can be recycled again for reutilization.
Regulation of oxygen and carbon dioxide levels.: The oxygen and carbon dioxide levels must be regulated. As oxygen is the basic requirement for respiration. The increase in carbon dioxide levels due to human activities is likely to cause respiratory diseases and health hazards in living beings.
An increase of erosion and siltation along waterways.: The erosion and siltation will likely to deposit nutrients and debris which may either contaminate the waterway or may cause eutrophication.
