The absolute zero is the temperature at which molecular motion ceases i.e translational kinetic of molecules become zero, but the molecules possess the potential energy, according to the Kinetic theory of gases. Thus, the absolute zero is not the zero energy temperature.
1.Double stranded
2.Single stranded
3.Contains the nitrogen base Uracil in place of Thymine
4.Backbone contains the sugar ribose
5.Backbone contains the sugar deoxyribose
6.Contains the nitrogen base Thymine in place of Uracil
Answer:
Three items that are unique to RNA are as follows:
2. Single-stranded.
3. Contains the nitrogen base Uracil in place of Thymine.
4. Backbone contains the sugar ribose.
Explanation:
B) False
2)The process of translation occurs at the ribosome
A)True
B) False
3)Transcription must occur before translation may occur
A) True
B) False
Answer:
1. False
2. True
3. True
Explanation:
hope this helps you :)
RNA contains ribose, not deoxyribose. Translation occurs at the ribosome. Transcription must occur before translation.
1) The sugar found in RNA is called deoxyribose
B) False
RNA contains the sugar ribose, not deoxyribose. Deoxyribose is the sugar found in DNA.
2) The process of translation occurs at the ribosome
A) True
Translation is the process of synthesizing proteins from mRNA at the ribosome.
3) Transcription must occur before translation may occur
A) True
Transcription is the process of synthesizing mRNA from a DNA template. It occurs before translation can begin.

Answer:
Screen door
Explanation:
Because it holds things out but let air in.
A plastic bag is an everyday object that behaves like an animal cell. The bag itself represents the plasma membrane of a cell, while the items inside the bag represent the different organelles, each with its distinct function.
An everyday object that acts like an animal cell could be a plastic bag. Let me explain why. The plastic bag acts like the plasma membrane, which is the outer lining of an animal cell. It holds everything inside, much like the way a plastic bag holds whatever you put into it. Then, you have your belongings inside the bag resembling the organelles, the functional components of an animal cell. Each item in the bag has a different purpose, similar to how each organelle in a cell has a unique function.

The final radii of the arteriole is reduced by the factor of 0.409 after the constriction of the arteriole.
The flow rate is defined as the amount of fluid flow through the artery in the given time period at the cross-sectional area.
The flow rate for the artery is given by:
Where, P is the pressure, r is the radius, is the viscosity, and l is the length.
The value of flow rate is reduced to 2.80 % of its natural values. The reduced flow rate is given as:
The ratio of the flow rate is given as:
The final radii of the arteriole is reduced by the factor of 0.409 after the constriction of the arteriole.

Answer:
The main factor that causes vasoconstriction is the high concentration calcium inside muscle cells.
Explanation:
When the vessels suffer vasoconstriction, the blood supply is decreased and in this way the heat of the body is maintained. The way this happens is because the blood can no longer reach the surface and therefore decreases outward heat radiation. The main factor that causes vasoconstriction is the high concentration calcium inside muscle cells. There are several factors that cause vasoconstriction, internal or external. Environment is one of the external factors, and what happens to the penguins' feet is an example for it, since they are trying to preserve body heat to survive.
