Answer:

d) B and C are both true            

Explanation:

Prokaryotic cells: The term "prokaryotic cells" are described as cells that don't consist of "membrane-bound organelles" or "true nucleus". However, the organisms that come under the domain of Archaea and bacteria tend to possess prokaryotic cells and it has been described that organisms that consist of prokaryotic cells are abundant in nature and make most of the Earth Biomass. Prokaryotic cells don't possess the nucleus rather have one chromosome.

In the question above, the correct answer is option D.

Which of the following observations helped Darwin shape his concept of descent with modification?
Zarrin [17]

Answer:

The correct answer will be option-D.

Explanation:

Darwin is best known for his theory of evolution which he proposes after collecting the specimens of plants and animals on his voyage.

He observed the similarity and differences of the morphological pattern as well as the species present in the area. On the basis of his conclusions, he suggested that organism get traits from their parents and species to change over time also called descent with modification.

One of the evidence that supported his concept is that he observed plant species in South America and found that these species closely resembled the species of the tropical regions of South America rather than species of the temperate region of Europe as the habitat was same.

Thus, option-D is the correct answer.

following a meal, glucose must move from the gut lumen, where there is a high glucose concentration, through membrane proteins a
True [87]

Following a meal, glucose must move from the gut lumen, where there is a high glucose concentration, through membrane proteins and into intestinal cells, where there is a relatively low level of glucose. this movement is called <u>diffusion</u>

This is simply because glucose moves from a region where it is highly concentrated in the gut lumen to a region of less concentration in the intestinal wall.

<h3>Diffusion</h3>

Diffusion can simply be defined as the movement of substances from a region of high concentration to a region of low concentration.

So therefore, Following a meal, glucose must move from the gut lumen, where there is a high glucose concentration, through membrane proteins and into intestinal cells, where there is a relatively low level of glucose. this movement is called diffusion

What information from the client would support the diagnosis of guillain-barré syndrome?
Rus_ich [418]

The most patients with typical GBS present with rapidly progressive bilateral leg weakness with hypo/areflexia in the affected limbs. In rare cases, patients can present with facial, oculomotor, bulbar, i.e. difficulty with swallowing and speaking, weakness, or primary sensory symptoms.

The clinical diagnosis of GBS needs to be confirmed by cerebrospinal fluid analysis and nerve conduction studies. Lumbar puncture is indicated in every case of suspected GBS.

The things to be monitor in Guillain-Barré syndrome (GBS) respiratory status of patients with GBS must therefore be carefully and frequently monitored. Pulse oximetry and blood gases are inadequate for early detection of failure because hypoxemia and hypercarbia are very late manifestations.

Darina [25.2K]

Answer:

red

Explanation:

When the source of light moves away or comes closer to an individual, the wavelength of the light decreases or increases respectively and the color of the light changes slightly in what is known as the <u>doppler effect</u>.  

When the light source moves towards an individual, the wavelength shifts towards the <u>blue</u> end of the spectrum, and the phenomenon is known as the <u>blueshift</u>. When the source of light moves away from an individual, the wavelength shifts towards the <u>red region</u> of the spectrum, and the phenomenon is known as the <u>redshift</u>.
