Out of the following given choices;
A. major changes in the structure of Earth's layers
B. major changes that occur in the solar system
C. major changes that are recorded in the fossil record
D. major changes in the
<span> arr</span>angement
of the continents
The answer is C.
Changes in the environment in prehistoric times can be best exhibited by the evolutionary
changes of living organisms. This is best shown
by fossil records. Changes in geological times are characterized by a high rate of varying individuals of a species
and with high extinction rates.

Leg bones
• long and skinny
Skull bones

Many skull bones are carved. Leg bones enable walking and standing. While skull bones are designed to protect the brain.
Answer:
The model is inaccurate because the base pairs are incorrect.
Explanation:
The model of DNA that the student made was:
G-G
A-A
T-T
C-C
G-G
A-A
T-T
C-C
The model is pairing the bases incorrectly since guanine (G) forms a base pair with cytosine (C) and adenine (A) with thymine (T). In other words, the bases do not pair with the same type.
The DNA strands, which have deoxyribose, phosphate groups, and different bases, are together thanks to hydrogen bonds between the pairs. The pair G-C has three hydrogen bonds, while the pair A-T has two hydrogen bonds.
