Answer:
The correct answer is that the spliceosome is non-functional.
Explanation:
A spliceosome refers to a composite and large molecular apparatus found mainly inside the nucleus of the eukaryotic cells. The prime function of the spliceosome is to remove the introns from a transcribed pre-mRNA, that is, a kind of primary transcript.
In case if the spliceosome machinery gets failed to function, the mRNA will not remove the introns, that is, the non-coding parts and retains it. This will eventually lead to the formation of longer mRNAs.
Answer:
Five (5)
Explanation:
A <u>total of five (5) paramecia </u>can be accommodated within the FOV.
The field of view of a microscope represents the area of the visible region under the ocular/eyepiece at a specific magnification. In other words, the diameter of the circular area visible through the ocular of the microscope at a specific magnification represents the field of view.
<em>If a paramecium was found to occupy 20% of the total field of view of a microscope at X40 magnification, then the total number of paramecia that can be accommodated within the field would be:</em>
100/20 = 5 paramecia
Cyril Ramaphosa the president of South Africa is currently 68 years old
Answer:
option D. and B. and C.
Explanation:
option a. atmosphere contains 78% nitrogen, but it is in the crude form and very few organisms can absorb nitrogen in the atmosphere. so it is necessary for the nitrogen cycle to take place. therefore option a. is false
option b. ATP, adenosine triphosphate, contain Adenine, which has a portion of nitrogen. And nitrogen is known to be one of the main components of energy storing molecules.
option c. Nitrogen is an important part of amino acid, proteins and any of such.
option D. nitrogen is required for all organic molecules of organisms.
Answer: lipids are nonpolar
Explanation:
because water is polar and lipid is non polar, so it is insoluble in water that is it floats water
