Explanation:
:) answer mom
The charge of object y will be positive since it will have excess proton and less electron.
What is positive charge?A positive charge is obtained when an atom losses its electron usually a metal. It simply defines the excess of proton in an atom or deficient of electron in an atom.
If object x acquires a negative charge, then object y must have supplied the excess electron to it.
Thus, the charge of object y will be positive since it will have excess proton and less electron.

c) CCG GCU AAG UGG
d) CCG GCA AAG UGG
Answer:
The Answer is D, trust. I got all of them wrong and the system showed that this was the correct one.
Explanation:
The transcription of G G C C G T T T C A C C to mRNA is CCG GCA AAG UGG. Hence, option D is correct.
What do you mean by Transcription?Transcription may be defined as a biological process that involves the transformation of a DNA strand into its mRNA sequence. It occurs in the nucleus of the cell.
In mRNA, Adenine is transcribed into Urcail instead of thymine. So, the mRNA sequence will be synthesized according to that.
Therefore, the correct option for this question is D.

Explain this term as related to fossils.
inference
To figure out something based on observation or provided information is termed an inference. Information about the fossils is used by geologists to draw inferences about the organisms that existed long ago.
What are fossils?Fossils are the remains of once-alive organisms that are altered geologically. The dead remains of past lives had been preserved by the earth's crust. They are of interest to geologists and are used to determine the age of rocks
Any living creature – animal, plant, bacteria, and fungus – can be fossilized, but because fossilization is a process of destruction, not all fossilized organisms survive. Most fossilized organisms are consumed, rot or die out in the environment before they can become fossils.
Under normal conditions, only the outermost layers of the most difficult animals and plants fossilize. However, sometimes the conditions are right to fossilize entire soft-bodied organisms.
