Gennadij [26K]

Scorpion cells undergo aerobic respiration, during aerobic respiration oxygen is used, and ATP is created.

During aerobic cellular respiration, glucose is absorbed with oxygen to form ATP, which can be used by cells. Carbon dioxide and air are formed as by-products. The overall extension to aerobic cellular respiration is: During cellular respiration, glucose and oxygen form ATP.

This process takes place in the mitochondria. So respiration occurs in animals and plants because both have mitochondria.

Aerobic respiration is respiration that requires oxygen while anaerobic respiration is respiration that does not require oxygen. Aerobic respiration consists of several stages, namely: glycolysis, oxidative decarboxylation, Krebs cycle, and the electron transport chain which have been discussed in the previous material.

In DNA fingerprinting explain how DNA moves through the gel
Zielflug [23.3K]

Answer:

B. The smaller DNA pieces travel farthest towards the positive end of the box

Explanation:

Gel-electrophoresis technique is a technique which is used to separate the fragments of DNA based on their size. The technique is employed in the DNA fingerprint analysis.

The DNA samples are loaded on one side of the gel and when an electric current is applied, the DNA moves from the wells towards the electrodes.

The DNA is a negatively charged molecule which travels through pores in the gel and reaches towards the electrode with positive charge. The smaller the size of the DNA fragment, the faster it moves.

Thus, Option-B is correct.
