3. How do multiple transmembrane proteins get inserted correctly into the membrane?

Multiple transmembrane proteins get inserted correctly into the membrane thanks to signaling sequences.

The amino acid chain of transmembrane proteins (pass through a membrane one or more times) are inserted into the membrane by translocation. Transmembrane proteins must enter the ER before their insertion in cytoplasm and their transport is co-translational (the process of translocation occurs while the protein is still being synthesized on the ribosome). Protein should contain:  

• Signal peptide or signal sequence is a sequence of amino acids at the N terminal that gets recognized by signal recognition particle (SRP). This sequence is involved in cotranslational translocation into ER, where the protein should be folded.

• A stop-transfer sequence-signals that translation of the protein should continue in the cytosol (not in ER).

You call to a friend from a boat floating in the ocean. Which best describes the changes in the speed of the sound waves as they
Alina [70]

The correct answer is: The speed of sound is faster in the water than in the air.  

The speed of sound is different between those two mediums because they have different densities. Since, water is denser than air, more energy is required to generate a wave but once it stars, it travels faster than it would do in air. Sound waves’ travel can be presented by particles that transmit the energy one to another as they bump. The sound speed is lower in the air (than in water) because particles are far apart, so they travel further before they collide.

What of the following is ordered from LARGEST to SMALLEST? Select one: a. virus, mitochondrion, hemoglobin, glucose, water molec
choli [55]

Answer:

c. mitochondrion, virus, hemoglobin, glucose, water molecule

Explanation:

The mitochondrion is a membrane which is found in cytoplasm of eukaryotic cells. It is also known as power house of cells. This is largest from virus, hemoglobin, water molecule and glucose.

Virus is second largest and is small infectious agent. It has capability to infect many organisms and living cells. Hemoglobin is protein which is present in red blood cells. Glucose is a type of sugar presence in the blood. Water molecule is composed of hydrogen and oxygen and is smallest among the others.

Biocentrism is not considered when looking at life-centered environmental ethics
Murljashka [212]

The given statement is not true.  

Biocentrism in an ecological and political sense, as well as, in an ethical perspective encompasses intrinsic value to all the living creatures. It is an understanding of how the earth functions, mainly as it associates with biodiversity.  

The term biocentrism covers all the environmental ethics, which outspread the status of the moral object from human beings to all the living creatures in nature. Biocentrism witnesses each species as a component of the living biosphere.  

It witnesses the outcomes of minimizing biodiversity on both the large and small scales and emphasis towards the innate values all the species exhibits towards the environment.
