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.
Answer:
1. Flower-The biological function of a flower is to affect reproduction, usually by providing a mechanism for the union of sperm with eggs.
2. leave-Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food
3. Stem-The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots
4. Roots-Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels ( xylem )

Answer:
<u>would increase, population, and chances of getting more food for survival.
</u>
Explanation:
By the increase in secondary consumers, that would give more food and energy and the ease of finding food for the tertiary consumers, which will give more energy for activities and therefore sexual activity can no longer be lacking the energy barrier, and due to that the population of tertiary consumers increases, eventually leading to the same effect and increase in Quaternary consumers.
The answer is A it's the action of purifying water
They would fall in the clumped or even category
