The sum of 8 and 5 times a number is 43. Which equation below can be used to find the unknown number?

Answers

Answer 1
Answer: Let the unknown number be x
The phrase “8 and” means addition so that’s 8 +
5 times a number is multiplication so that’s 5 times x, or simply, 5x
So the correct equation would be 8 + 5x = 43
And the correct value for variable x is 7
8 + 35 = 43
Answer 2
Answer:

8+5n=43 is the answer

E) because the exons remain present within the final mature RNA product of that gene after introns have been removed by RNA splicing.

Why do we need to destarch a plant

Answers

in photosynthesis experiment, the effect of the light will be observe during the starch production- thus you need to have a plant without a starch to observe if the starch is produced during photosynthesis. Letting the leaves of the plant deprived from light for 48 hours will be forced to use its reserved starch making the storage of the starch decrease.

A vaccine puts into the body weakened/dead pathogenic material, which by itself is incapable of causing disease. How does this help to protect the body in the case of infection by a live pathogen?

Answers

During the process of vaccination, an attenuated pathogen is inserted into the body the organisms. The attenuated pathogen is able to provoke the primary immune response in the body of the organism without causing any harm.

Once the primary immune response is generated, the body creates a memory in form of antibody to the pathogen. After vaccination, if the pathogen infects, the body recalls the memory and generates a secondary immune response. The intensity of the secondary immune response is much higher than the primary one, so, as soon as the pathogen enter in the body, the antibodies against it are activated and result in defeating the infection.

For a better understanding purpose, the intensity of the primary and the secondary immune response is given in the figure:

Answer:

d.  a vaccine causes the secretion of antibodies which remain in blood and fight the pathogen at the time of an infection.
