dimulka [17.4K]3 years ago
5 0

Answer:

 Anaerobes are not able to have growth in the presence of much of oxygen environment as they do not have catalse .Catalse is the enzyme for clearance of oxygen.There are also anaerobes protects their own self from oxygen by production of an enzyme known as super oxide dismutase. Therefore, it is not easy task for creation an oxygen-absent environment for anaerobes in the vitro so they cannot be grown in vitro.

Which of these statements is true:
PilotLPTM [1.2K]

Answer:

Option a is the one, that is true.

Sister chromatids separate in anaphase of mitosis and anaphase Il of meiosis

Explanation:

After the interphase in the cell division cycle, the mitosis process begins, which is composed of 4 phases, prophase, metaphase, anaphase and telophase. The prophase occurs when the chromatin is condensed and the mitotic spindle is formed, the metaphase the chromosomes align along the cell equator, in the anaphase the separation of the sister chromatids occurs and in the telophase finally the heterochromatin is converted into euchromatin and the envelope is formed nuclear cell.

Meiosis, which is the cell division of germ cells, also has the same phases but they occur on two occasions: prophase I, metaphase I, anaphase I and telophase I for meiosis I and for meiosis II, prophase II, metaphase II, anaphase II and telophase II. In the anaphase I the homologous chromosomes are separated, they are condensed in the prophase II while in anaphase II the chromatids are separated.

What would be a consequence of a person having na levels in the blood and interstitial fluids that are well below normal?
Vladimir79 [104]

Consequence of a person having Na levels in the blood and interstitial fluids is that Neurons would not be able to undergo normal action potentials.

Nausea and vomiting. Lethargy, or low energy. Headache and confusion. Mental status changes. Normal motion capacity reaching the end of the axon. while an movement potential reaches the quit of an axon, vesicles fuse with the plasma membrane and launch neurotransmitter into the synaptic cleft.

At the peak of the action capability, two methods occur concurrently. First, a number of the voltage-gated sodium channels begin to near. 2d, many more potassium channels open, allowing wonderful fees to depart the mobile. Neurotransmitter is released from nerve ending when something must be excited or inspired , however when the task is carried out the neurotransmitter needs to be eliminated, otherwise the receptor may be in continuous nation of excitation which can be harmful.

What would be a consequence of a person having Na+ levels in the blood and interstitial fluids that are well below normal?

A) Neurons would all be depolarized.

B) Neurons would not be able to undergo normal action potentials.

C) Action potentials would occur with greater frequency.

D) Neurons would remain refractory following closure of voltage-gated sodium channels.

E) K+ channels would open to compensate for changes in membrane potential.

Hence the answer is option B Neurons would not be able to undergo normal action potentials.
