- There are most chances of sexual reproduction.
Answer:
two of the gametes will Java chromosomes identical to the chromosomes found in the original diploid cell,while two of the gametes will have chromosomes that are different
Answer:
B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules
Explanation:
DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.
In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.
Answer:
All the different plants, animals, fungi, microorganisms, and variety of ecosystems found on Earth
Explanation:
Biodiversity can be broken down into "Biological" and "diversity" which means the how diverse in number and variety is the life found on Earth. Life represents all living organisms like plants, animals, microbes etc.
Based on this, all the different plants, animals, fungi, microorganisms, and variety of ecosystems found on Earth is the option that best defines biodiversity. The other options leaves out the variety (talked about only one species) and biological aspect of the term.
