Answer:
the colour change
Explanation:
because experimental group refers to the things that are exposed to or get affected by the independent variable
Answer:
A Ligase
B False
C To separate the double‑stranded DNA
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories in order to make millions of copies of a specific sequence of DNA. PCR requires deoxynucleotide triphosphates (dNTPs) to synthesize new copies of the target DNA fragment, a thermostable DNA polymerase that adds nucleotides to new DNA strands, and primers that attach to complementary ends at each DNA strand. PCR has three phases: 1-Denaturation, where the double-stranded DNA molecule is heated to separate it into two single (separated) strands; 2-annealing, where the temperature is lowered in order to allow the primers to attach each DNA strand, and 3- extension, where the temperature is increased (again), and the thermostable DNA polymerase adds the appropriate dNTPs to new DNA strands. In consequence, annealing occurs at the lowest temperature. Moreover, during the denaturation stage, the temperature is increased at 90–95°C in order to denature the DNA strands into single strands.
The correct answer is: asexual reproduction via spores
Sporogenesis is the type of asexual reproduction which includes production of reproductive cells - spores, and the growth of a new organism from them. Spores can be produced by bacteria, fungi, algae, and plants. Spores are beneficial for a species that live in an area prone to droughts because spores can do through the resting, or dormant stage. Dormant stage can last until period of unfavourable conditions stops.
