Answer: he crystallized tobacco mosaic virus ( TMV)
Explanation
Answer:
<h2>consensus</h2>
Explanation:
Such type of the nucleotide sequence that is mostly present at each position is called a consensus sequence. This sequence plays an important role in the sequence alignment and some other molecular biological research and some other fields. Generally, it is made up of a small segment of the nucleotide and also considered as a conserved sequence motif because its presence is conserved on the position where it is present.
Answer:
B. So you can always see the entire object at the higher magnification
Explanation:
A microscope is used to view objects smaller than the naked or unaided eyes can see. The objective lens, in conjunction with the occular or eye lens, is used to achieve this purpose. The objective lens are of different magnifications as follows: 10X, 40X, 100X etc.
However, as the magnification increases i.e. higher objective, the object in the field of view becomes smaller and less focused. Hence, the object in the field of view must first be centered at a lower magnification/objective lens before changing to a higher one in order for the entire object to be seen at a higher magnification.
Answer:
B) meteorite sample
Explanation:
The age of the solar system, derived from the study of meteorites (thought to be the oldest accessible material around) is near 5 billion years; that of the Earth is taken as 4.6 billion years. The oldest rocks on Earth are dated as 3.8 billion years.
