Answer:
From higher concentration to lower.
Explanation:
The oxygen diffuses out from a region of higher concentration to the region of lower concentration because of diffusion. The air contain high amount of oxygen and human body has low oxygen level so the oxygen moves from the air to the lungs of the human body from there oxygen is loaded in the hemoglobin while on the other hand, carbondioxide is removed from the blood into the lungs which goes outside the body through breathing.
Parasitism.
There are several types of biotic relationships that is occurring
every single moment in the ecosystem and one is parasitism. In this scenario
with human beings and mosquitos, this phenomenon of interaction is
distinguished as parasitism where mosquitos draws blood that contains nutrients
from the human tissue to use it as its source of food and then leaves harmful
substances and bacteria in the human’s blood stream.
Answer and Explanation:
Prokaryotic Translation :
Initiation :
- First amino acid participating is f-methionine.
- Requires three initiation components are
,
and 
- Initiation complex framed at Shine-Dalgarno succession of mRNA.
- There is no concept of Kojak rule in prokaryotic.
Protein synthesis :
- Faster process. Adds 20 amino acids per sec.
Termination :After translation, the formyl group of first formylated methionine is removed. Methionine is retained in the polypeptide chain
Eukaryotic Translation :
Initiation :
- First amino acid taking part in translation if methionine.
- Requires a set of eleven initiation factors, named as eIFn.
- Initiation complex formed at 5’ end of mRNA.
- Kojak rule followed
Protein synthesis :
- Slow process. Adds 1 amino acid per second.
- mRNA is mono-cistronic.
- Occurs on 80S ribosome.
Termination :
Initiating methionine codon is removed from the polypeptide chain.
