How do some plants survive the intense desert heat and drought?

Biology

viva [34]3 years ago

The correct answer is:

Plants close their stomata during times of intense heat or drought in order to prevent water loss and maintain homeostasis.

Explanation:

Guard cells tend to open stomata within the day when there are lots of day and close stomata at night when the sun is not present and photosynthesis is not happening. They will also close stomata if the air is dry or hot, which minimizes water waste indoors evaporation.

I think the correct answer from the choices listed above is the first option. Some plants survive the intense desert heat and drought because these plants  close their stomata during times of intense heat or drought in order to prevent water loss and maintain homeostasis. Hope this answers the question.

Transcription in bacteria differs from transcription in a eukaryotic cell because __________________________. (a) RNA polymerase
Serggg [28]

The correct answer is: (a) RNA polymerase (along with its sigma subunit) can initiate transcription on its own.

More differences between prokaryotic and eukaryotic transcription:

• In prokaryotes transcription occurs in the cytoplasm (unlike in eukaryotes in nucleus) and it is simultaneous with translation,

• In prokaryotes there is only one type of RNA polymerase (in eukaryotes there are three types of them).

• There is no sigma subunit in eukaryotes, the initiation of transcription begins thanks to initiation factors.

• Promoter region in prokaryotes contains pribnow box, while in eukaryotes it contains TATA and CAT box.

Please identify <br> Label A<br> Label B<br> Label C<br> Label D
timurjin [86]

Answer:

Label A: Nucleus

Nucleus can be described as the organelle in which the DNA is enclosed. The nucleus is found in every eukaryotic cell.

Label B: Vacuole

Vacuole can be described as an organelle which is used to store material such as waste. Hence, vacuole is known to be the storage house of a cell.

Label C: Ribosomes

Ribosomes can be described as structures which are present usually on the rough endoplasmic reticulum. The process of translation occurs in the ribosomes and they are hence known to be the protein manufacturing units if a cell.

Label D: Centrioles

A centriole is a cylindrical organelle which is usually made up of the protein tubulin.

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.
