A)
Therefore:Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote).
b)
Therefore:Crossing results in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).
c)
Therefore:Crossing results in 100% (homozygous recessive).
we risk losing due to climate change is food. Thus option C is correct.
<h3>What are the impact of climate change on species ?</h3>
Climate is the crucial factor for all living organism, as it determine whether an organism is going to survive or not.
Global warming is one of the major factor resulted from release of green house gases.
It leads to habitat loss, change the migration capabilities, alter the competitive relationships.
The fate of the species completely depend on climate change, those who are able to move new area with new climatic condition they will meet their physical, biological, and climatic needs.
Thus option C is correct.

Answer:
Explanation:The Carnian Pluvial Episode (Late Triassic) was a time of global to a major extinction event and might have been the trigger of the spectacular known delta system by area (1,000,000 km2) in Earth history.
Firstly, the enzyme, DNA Helicase breaks the Hydrogen bonds between a specific region of the DNA molecule and unwinds the duplex DNA molecule at the targeted gene sequence site.
Then, RNA Polymerase binds at the 3` site of the gene sequence of the sense/coding strand(only one strand) that acts as the template for mRNA synthesis. RNA Polymerase then matches free nucleotides by complementary base-pairing(A-U & C=G), working in the 5`to3` direction. Hydrogen bonds then form between the complementary bases, holding the nucleotides in place. Each free adjacent nucleotide is joined at 3` ends by Condensation reactions with the other to form Phosphodiester bonds.
Once the mRNA molecule is formed, it is separated from the synthesis complex and leaves the nucleus through pores in the nuclear envelope to moves towards ribosomes for Translation.
Lastly, the DNA double helix rewinds by forming Hydrogen Bonds.
"Identical twins come from a single fertilized egg, or zygote, that splits in two. Both halves contain the same DNA and eventually form two fetuses. But clones are formed in a different way. The first step in making a clone is to empty the DNA out of a fertilized egg".
