Answer:

I think ‘there will be less oxygen available for the aquatic life due to the microbial activity’. Too much microbial activity utilizes the oxygen dissolved in the water hence making the waters anoxic. This occurs especially after algae blooms. When the algae grow exponentially and later die, microbes that oxidize the organic matter for energy utilize the oxygen and cause dissolved oxygen in the water to deplete. This hence suffocates other aquatic life.

answers: When dissolved oxygen becomes too low, fish and other aquatic organisms cannot survive.

explanation: The colder water is, the more oxygen it can hold. As the water becomes warmer, less oxygen can be dissolved in the water.

3.a An antibiotic is added to a large population of bacteria. Explain why not all bacteria die?

drek231 [11]

Answer: Antibiotic Resistant Mutation

Explanation: Not all of the bacteria die because there are individuals in the population that have an antibiotic resistant mutation, which causes them to be adapted to dealing with the antibiotic. There will be a large population of bacteria again because the ones with the mutation survive, reproduce, and pass the antibiotic resistance trait on.

If a cells nucleus has 55% adenine bases, how many cytosine bases will be present?

Nostrana [21]

If a cell’s nucleus has 55% adenine bases it also has 55% thymine bases, so the percentage of cytosine bases is 45% as same as guanine bases.

This is known as Chargaff's rule which states that DNA should have a 1:1 ratio of pyrimidine and purine bases (the amount of guanine should be equal to cytosine and the same thing with adenine and thymine).

DNA molecule globally has percentage base pair equality: %A = %T and %G = %C.

Músculos: DELTOIDES, BICEPS, ADUCTOR, PECTORAL, GEMELOS, DORSAL, CUADRICEPS, IZQUIOTIBIAL, CORAZON, ABDOMINAL.

Articulaciones: CODO, MUÑECA, CADERA, TOBILLO, HOMBRO, CRANEO.

Explanation:

Los huesos son órganos que tienen la función de dar estructura, protección y soporte al cuerpo. A los huesos se le unen los músculos, los cuales hacen que los huesos se muevan al contraerse estos. Las articulaciones unen los huesos entre sí y permiten junto con los músculos el movimiento del cuerpo y de sus diferentes partes.
