I found the attached image on the internet and I believe it has the tiles referred to on the question.
As we can see on the image, the A-site, P-site, and E-site are represented. The A-site is occupied by the tRNA linked to the growing peptide chain. The P-site is the one occupied by the tRNA that works accepting the growing protein for peptide bond formation.
Firstly, the protein is formed, it is the
first tile from the left.
Then, the
first tile from the right is where the Leu is formed.
On the
second tile from the right the Leu is then added to the protein.
The process is then repeated again as there are two cycles of elongation adding a Leu in each of them:
third tile from the right,
third tile from the left,
second tile from the left.
Answer:
C) polarity
Explanation:
The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.
- In water molecules hydrogen bonds provides a special dipole - dipole attraction.
- Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine).
- This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge.
- This makes the molecule of water polar.
- By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.
This property of water is polarity of water.
Answer:
The innate or nonspecific immune system includes two lines of defense in the human body. Non-specific means that it does not act on the specific pathogen. It works equally to keep all types of pathogens such as bacteria, viruses, parasites et cetera out of the body.
The first line of defense includes physical barrier which prevents the entry of pathogens into the body. It includes skin, respiratory tract, gastrointestinal tract, cilia, nasopharynx, eyelashes, and body hairs.
It also includes chemical barriers such as mucus, gastric acid, bile, tears, sweat, and saliva.
The second line of defense includes anti-inflammatory responses, fever, and nonspecific cellular responses such as phagocytes, macrophages, complement system et cetera.
Thus, the virus has to pass physical, chemical, and nonspecific cellular responses of the body in order to infect the body.
<span>The answer is a) mitosis, meiosis. Body cells may produce additional body cells by means of mitosis. Organisms that reproduce sexually produce gametes by means of the process of meiosis. Mitosis is a process which results in two identical cells being produced through division, whereas meiosis results in the splitting of a cell to create two genetically different daughter cells. </span>
Yes, we can recover it. But not the same as before. Maybe we will make a new one. By planting trees and cleaning the area.The loss of biodiversity has two significant impacts on human health and the spread of disease. First, it increases the number of disease carrying animals in local populations. ... At the same time, habitat fragmentation brings humans in closer and more frequent contact with these disease carrying species.Participating in Biodiversity Conservation. Identify locations of critical wildlife habitat for species at risk and the threats to these areas. ... Keep vehicles on main roads to reduce the spread of weeds and disturbance to wildlife. Monitor and assess your pets' impact on biodiversity.
