how do potassium channels select the ion that can travel through the channel? group of answer choices membrane-spanning subunits concentration pore loop voltage

Answers

Answer 1

Answer: Potassium channels allow K+ ions to easily diffuse through their pores while effectively preventing smaller Na+ ions from permeation. ... This selection process occurs at the narrow selectivity filter that contains structurally identified K+ binding-sites

Explanation:

Answer 2

When the Potassium channels allow K+ ions to easily diffuse through their pores while effectively preventing smaller Na+ ions from permeation. Although when This selection is processed occurs at the narrow selectivity filter that contains structurally identified K+ binding-sitesAfter that, The remarkable ability of the potassium channel to pass that is only potassium ions is accomplished by a selectivity filter at one end of the pore, as shown here from PDB entry 1k4c. when To pass through the selectivity filter, that is each potassium ion has to shed these water molecules.

What is the difference between El Nino and La Nina in science terms of climate?

Answers

Answer:

El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds. La Niña is the opposite – a cooling phase of ENSO that tends to have global climate impacts opposite to those of it. El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.

Hope this helps

Answer:

Well, El Niño(warmer environment) impacts weather systems around the world, while La Nina(cold environment) tends to have global climate affects opposite to El Nino.

which muscle group relates best with the term midline?

Answers

The oblique is the muscle group that best relates with the term midline.

The anterolateral abdominal wall contains a muscle group in which there are flat muscles whose fibers originate in the posterolateral part, pass forward and become an aponeurosis towards the midline:

The external oblique muscle is the thickest and most superficial of the three muscles on the lateral wall of the abdomen.

It follows an inferomedial direction and the muscle-tendon limit descends in such a way that, towards the midline and also below the height of the anterior superior iliac spine, it is completely transformed into an aponeurosis.

The aponeurosis of the external oblique joins that of the internal oblique and passes in front of the rectus abdominis; its fibers intersect in the midline with those on the opposite side and contribute to the linea alba.

Therefore, we can conclude that the oblique is the muscle group that best relates with the term midline.

In living organisms the cell
cycle is closely regulated.
What do you think will
happen if cell division is not
controlled?

Answers

Answer:

Explanation:

Disruption of normal regulation of the cell cycle can lead to diseases such as cancer. When the cell cycle proceeds without control, cells can divide without order and accumulate genetic errors that can lead to a cancerous tumor

The cell life cycle is controlled meaning that:

The reproduction of the cell is controlled.

The cell has a "programated death" meaning that at some point, all normal cells die.

If there is a problem with these (uncontrolled reproduction or cells that just not die) a tumor will appear.

Where the tumor is just a mass of these cells that reproduce uncontrolled and that don't die naturally.

So the thing that happens if cell division is not controlled, is that a tumor will appear.

In eukaryotes, gene expression is regulated mostly by _____.

Answers

Answer:

Gene expression in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription.

Explanation:

In eukaryotes, gene expression is regulated mostly by transcription factors.

What are transcription factors?

Transcription factors are proteins that bind to DNA in the promoter region of a gene, and they play a critical role in controlling when and to what extent a gene is expressed.

They can either activate or repress gene expression by promoting or inhibiting the recruitment of RNA polymerase. Transcription factors are themselves regulated by a variety of signals, including hormones, growth factors, and other external cues, as well as by feedback loops and other regulatory mechanisms within the cell.

Ultimately, this complex interplay of factors allows eukaryotic cells to precisely control which genes are expressed, when they are expressed, and to what degree, enabling them to respond to changing internal and external environments.

Answers

Answer:

Most plants are auto trophic able to use sunlight as their primary source of energy,in a process called photosynthesis.This process enables them to turn carbon dioxide from the air into food,The carbon and oxygen which they need in order to build up their bodies ultimately comes from this carbon dioxide.

All animals are heterotrophs, which means that they cannot make their own food as plants do. Rather, animals must obtain the energy, carbon, hydrogen, oxygen, nitrogen, and minerals they need by consuming other living things. Animals are also animate, which means that they are capable of movement.
