<h2>Succession </h2>
Explanation:
Succession is a phenomenon in which older communities are replaced by advanced and newer communities
- Primary succession is the one in which succession occurs at newer area where none of the community previously evolved
- Secondary succession is the one in which the substrate has already been prepared by the older communities so that the newer community which will arrive grow faster that is why secondary succession has faster pace
- Glacial retreats leave behind nothing but bare rock as they retreat from an area, leaving barren land from which primary succession can occur which enables scientist to study plant succession
Answer:
the answer is 3.2 x 10⁴
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology to exponentially amplify a specific DNA sample from a small amount of DNA. For this purpose, the PCR technique uses: 1- a DNA polymerase enzyme in order to synthesize new DNA copies and 2- one pair of DNA oligonucleotides (primers) which are complementary to the ends of the target DNA sequence. During each round of PCR, the double-stranded DNA template is unwound and each strand is used to synthesize a new DNA strand, thereby forming two new double-stranded DNA molecules. In consequence, each round of PCR doubles the amount of DNA.
All cells require ATP for energy.
The correct choice is D.
A karyotype is the layout of chromosomes, in size order from largest to smallest. These chromosomes are ALWAYS in pairs, meaning that it would be easy to notice which of the 23 chromosome pairs have 3 chromosomes instead of the usual pair.
Answer:
Mitochondria is the Powerhouse of the cell.
Explanation:
You use your muscles for basically everything you do. So, it wouldn't be more surprising if the muscles need more energy. You need them to have more energy or you wouldn't be able to do anything.
