I don’t know the answer to this question
The best answer is C.
When an individual suffers a bacterial infection in the legs, immune proteins called acute phase proteins bind to the surface of the bacteria by a process called opsonisation.
Opsonised bacteria are therefore coated with molecules (self antigens) that phagocytic cells recognize. Activated phagocytes engulf and destroy opsonized bacteria by "swallowing " (engulfing) them.
Inside the phagocyte, enzymes break down the bacteria onto small fragments just the way food is broken down by enzymes in the digestive system. Phagocytes then present the fragments on their surface which helps in the final destruction of the bacteria within the phagocyte.
Answer: <u>Option A, OPEC
</u>
Explanation: Around 80 percent of oil production was accounted by OPEC in the year 2018. It is an organization of fifteen countries, which contain majority of oil reserves. Mainly the oil comes from the middle-eastern countries; namely Kuwait, Iran, Iraq, Qatar, etc.
United Nations and European Union hold very minute share in world's oil production. Exxon's share is also less than ten percent.
While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases oxygen
Answer:
Transgenic organism:
Transgenic organism may be defined as the organisms whose genetic makeup has been modified by the molecular techniques. These transgenic organism are mainly produced in the laboratory for research work. The genes of one species can be modified or some other gene has been inserted in the organism.
Advantage of transgenic crop.
The transgenic crop has been produced by the genetic alteration of the crop. The main advantage of the transgenic crop is to develop the enhanced quality and quantity of crop. Vitamin rich golden rice has been produced by the transgenic crop.
