Do viruses carry out all life processes? If not, which are they missing
Molodets [167]

Answer:

No, they only carry out reproduction.

Explanation:

individual viruses don't carry translational machinery, namely, the proteins needed to read their DNA and RNA and build new viruses. They invade a cell and hijack its genetic tools to do it for them.

Develop a hypothesis to explain why you think eurypterids developed legs even though they lived on the ocean floor.
expeople1 [14]

I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.

How do the structures in an organism relate to their functions?
finlep [7]

The study of the relationship between structures and functions is at the very heart of biology. This relationship is expressed in living beings by the adaptation of the first to the second and poses a series of absolutely fundamental problems, such as the relationship between causality and finality, analogy and homology, structural improvement and evolutionary level, etc.

For example, the structure of the hand is related to its function, thanks to the fingers and the thumb it is easy to wear and store objects.

The zigzag structure of the intestine is related to its absorption function, as this makes it possible to increase the contact surface between the alimentary bolus and the intestinal wall, and thus to increase the absorption.

Which of the following conversion factors would you use to change 18 meters to kilometers?
Y_Kistochka [10]
In converting a number with the unit of meter into kilometer we must use the conversion factor 1 km per 1000 meters.This is because in 1 kilometer there are 1000 meters and then the unit to be converted is already in meter so we need to divide it for us to convert.

Which of the following characteristics is directly related to the coding of a single amino acid during the process of translatio
likoan [24]

Answer:

C) the three-base sequence of mRNA

Explanation:

Three-base sequence of mRNA is called codon. One codon specifies a single amino acid. There are 64 codons in eukaryotic cells and three of them are stop codons (non-coding).

tRNA have three-base sequence called anticodon which is complementary to specific codon. During the process of translation codon and anticodon are paired which leads to addition of amino acid to growing polypeptide chain. Newly added amino acid is carried by tRNA.
