There are two types of mutations, positive and negative. A positive mutation benefits the individual and the negative harms the individual. In some cases the mutation doesn't affect the individual at all. So, <u>if the wrong amino acid is put into sequence the effects could either be positive, negative, or neutral.</u>
In plants, a new cell wall is fashioned between the new daughter cells. In animal cells, the cell membrane constricts to pinch the parent cell into daughter cells.
Answer:
Bacteria and protozoa are the examples of unicellular organisms.
Explanation:
Unicellular are the organisms which madeup of single cell such as bacteria and protozoa. Bacteria are prokaryotic organisms i. e. no true nucleus. Some bacteria make their own food from photosynthesis and some bacteria are parasites and other are decomposers.
Protozoa are eukaryotic organisms which are heterotrophic in nature i. e. feed on other organisms. Amoeba and paramecium are the examples of protozoa.
Option D
polymerase chain reaction (PCR) do Makes more copies of a sample of DNA
<u>Explanation:</u>
A procedure to create several portraits of a distinct DNA section is termed as Polymerase chain reaction. In other words, it is a lab routine handled to compose various representations of a portion of DNA. PCR is extremely explicit and can be utilized to increase, or model, a particular DNA destination from a hybrid of DNA particles.
In PCR, the effect is regularly cycled within a range of temperature variations, which deduct countless models of the destination range to be exhibited. PCR intends to obtain sufficient of the objective DNA region that it can be examined or applied in some other way.
If you have a second fixture around, you can use the same test of putting a tube in a working socket and see if it lights. It is not uncommon in fluorescent fixtures to have the ballast burn out. You may detect a burnt smell or see the bulbs flickering.
