Which describes the process of glycolysis?
question 14 options:

aerobic process that breaks down glucose

aerobic process that manufactures glucose

anaerobic process that breaks down glucose

anaerobic process that manufactures glucose

The correct answer is anaerobic process that breaks down glucose.

Explanation:

Glycolysis helps in the catabolism or breakdown of glucose into pyruvate.The glycolysis process does not requires oxygen to proceed it simply means glycolysis occur in absence of oxygen.

       The cellular respiration will be aerobic or anaerobic depending on the reaction carried out by the pyruvate.

 If the pyruvate is converted to acetyl CoA then the process is aerobic respiration but if the pyruvate is converted to either lactate or ethanol then the process is called anaerobic respiration.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
