Answer:
DNA molecular weight standard controls, also known as DNA ladders
Explanation:
A DNA ladder is a molecular-weight size marker used to identify the size of the PCR products in a gel electrophoresis. The DNA ladder consists of a solution containing double-stranded DNA fragments with different molecular weights including, among others, 50 base pairs (bp), 100 bp, 1000 bp and 3000 bp DNA fragments. The concentration of each DNA fragment in the DNA ladder must be sufficiently high to be visualized on the electrophoresis gel.
D because the common types of phytoplankton is cyanobacteria,
silica-encased diatoms, dinoflagellates, green algae, and chalk-coated coccolithophores.
Answer:
<em>The correct option is A. mitospore</em>
Explanation:
A mitospore can be described as a haploid or diploid spore. Generally, a spore is formed by meiosis but under certain conditions it can form by the process of mitosis and is known as mitospore.
When spores are formed by sexual methods, meiosis occurs. When they are formed by asexual methods, mitosis occurs. Asexually, there are different ways by which mitospores form by mitosis.
Answer:
False.
Explanation:
It is just a regular mutation.
Answer:
4 1/4
Explanation:
17/4 = 4/4 + 4/4 + 4/4 + 4/4 + 1/4
4 + 4 = 8
4 + 4 = 8
8+8=16 = 16/4
16/4 + the 1/4 remaining in the equation = 17/4
so 4/4 + 4/4 + 4/4 + 4/4 = 4
4 + 1/4 = 4 1/4
sorry if you couldnt follow along. I am not good at explaining things but the answer is 4 1/4
(I also took the test)
