Answer:

Aquaporin protein is a type of protein composed of a bundle of six transmembrane α-helices.

Explanation:

Aquaporin protein is a type of protein composed of a bundle of six transmembrane α-helices. These aquaporin protein have different size of water channels that allow water through to pass through it but it does not allow glucose to move through it due to its large size. The direction of water movement is toward the cell because there is low water inside the cell as compared to outside environment so the water moves inside the cell and  rate of water movement slows down over time due to filling of empty spaces with water.

Which of the following is a correct difference between active transport and facilitated diffusion?
sweet-ann [11.9K]

Answer:

Active transport requires energy from ATP while facilitated diffusion does not

Explanation:

Active transport and facilitated diffusion with the use of channel and carrier proteins are both ways by which ions, polar and large molecules cross a selectively permeable membrane.

The major difference is that; Active transport transport these particles from a low to high concentration, which is against concentration gradient and hence, energy is required to perform the task

Facilitated diffusion transport from a high to low concentration, which is through a concentration gradient and hence, no energy is required to perform the task.

Is the neurone a cell, tissue or an organ?
cupoosta [38]

Answer:

Cell

Explanation:

Glial cells and neurons are the two types of cells that make up the nervous system. Four tasks are carried out by glial cells, which make up the nervous system's supporting framework: Give the neurons structural support. protect the neurons. A neuron is a specialized, impulse-conducting cell that is the functional unit of the nervous system, consisting of the cell body and its processes, the axon and dendrites.  Three components make up neurons (nerve cells), which perform the integration and communication processes. Axon terminals, dendrites, and axons. The cell body, also known as the soma, is their fourth component and is responsible for the fundamental functions of neurons. In the illustration to the right, a "typical" neuron is depicted. The neuron, a specialized cell created to send information to other nerve cells, muscle cells, or gland cells, is the basic functional unit of the brain. Neurons are nervous system cells that communicate information to other nerve, muscle, and gland cells. Axons, dendrites, and a cell body make up the majority of neurons.

Foreign particles circulating in the blood are filtered by the ____________.
babunello [35]

Answer:

spleen is a correct answer.

Explanation:

Foreign particles circulating in the blood are filtered by the spleen

Spleen is present in the upper left area of the abdomen.

Spleen function is to filter the foreign particles from the blood as it acts as a blood filter.

Spleen recognizes the damage and old red blood cells, foreign particles.

As the blood flows into the spleen the white blood cell present remove and they attack the foreign particles.

Spleen acts as a blood filter by this way foreign particle are removed and the blood is filtered.

Thus(spleen) is a correct answer.
