Answer:
This is the site of gaseous exchange
Explanation:
Gaseous exchange is the mechanism by which oxygen is substituted for CO₂ in the body. CO₂ laden blood is carried to the alveoli, which is wrapped with numerous capillary beds and with walls that are thin. When a person inhales, the difference in the partial pressure of the various gases ( oxygen and carbon dioxide) causes them t move down their concentration gradients, with CO₂ diffusion into the lungs from red blood cells, and oxygen binding to the haemoglobin in the red blood cells, after which they are carried to all body tissues for cellular respiration. During exhalation, the CO₂ in the lungs is expelled to the exterior and the process repeats.

An 8-mer oligopeptide has the following amino acids:
A D E E F M W Y (two Es are present)
Here is your evidence:
1. Edman degradation produces A.
2. CNBr produces a 5-mer and a 3-mer that contains W.
3. Chymotrypsin produces two dipeptides and a tetrapeptide. The tetrapeptide has a total net charge of -4 at pH 12.5.
4. Staphylococcal protease in phosphate buffer produces a tetrapeptide (4-mer), dipeptide, free D, and free W.
5. Staphylococcal protease in acetate buffer produces a pentapeptide (5-mer), dipeptide, and free W.
Put in the sequence of the 8-mer (use caps here) i.e. ABCDEFGH.

The RNA that is translated into a polypeptide is ______ RNA
Answer:
The RNA that is translated into a polypeptide is messenger RNA
Explanation:
Brainliest please! :)
The RNA that is translated into a polypeptide would be the messenger RNA.
For translation to occur, genetic information on DNA is first transcribed to messenger RNA in the nucleus in a process known as transcription. The pre-mRNA then undergo some modifications before being transported to the cytoplasm where it gets translated into protein.
The mRNA binds to the ribosome and another RNA, the transfer RNA, binds with its anticodons. The genetic codes on the mRNA are read in 3s and the respective amino acids corresponding to the anticodons on the tRNA are released. The amino acids are then linked together by peptide bonds.

How does a flash flood compare to flooding?
Answer:
Flood: An overflow of water onto normally dry land. ... Ponding of water at or near the point where the rain fell. Flooding is a longer term event than flash flooding: it may last days or weeks. Flash flood: A flood caused by heavy or excessive rainfall in a short period of time, generally less than 6 hours.
Explanation:
Answer:
They both cause floods and fill up some places and they are both sometimes caused by rains or broken dams for a pretty long time. Flood is caused by rain and bad weather while flash flood is the result of water overflowing from a contained location like a lake, river or reservoirs. Flood is a term that can be used to describe any type of water overflow while flash floods are specific to broken dams, overflowing lakes and clogged rivers. The word flood both stands for their meaning.
What are factors in an experiment that are not changed but are kept the same for both and normal group and the experiment group?
Explanation:
The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is "controlled" or held constant in the control group.

The oxygen released during photosynthesis comes from molecules of water
True or False
Answer: False
Photolysis takes place in the light dependent reaction of the photosynthesis. The reaction can be represented as: H 2 O + 2 photons --> 2 e − + 2H + + O. Here, the electrons released are accepted by the photosystem to fulfill the electron gap. The last electron acceptor is the oxygen and thus, the oxygen is liberated from the water molecule. The experiments conducted by Samuel Ruben and Martin Kamen by using radioactive isotopes helped to prove that the oxygen liberated during photosynthesis came from photolysis the water.
Explanation:
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.Carbon dioxide is released during photosynthesis. Plants which synthesise their food themselves are called saprotrophs.
