Answer:
A-2
B-4
C-1
D-3
Explanation:
In description A, the car is first moving at a constant speed, which means it will have a constant slope. Then, it stops, which causes a slope of 0. Finally, it moves in the opposite direction, which will cause a negative slope. The second graph has a positive, zero, and negative slope; therefore, it fits A.
Description B has a constant slope, a zero slope, and a higher slope. Graph 4 goes up normally, then stops, and finally goes steeper. This fits description B.
Description C has a constant and then a higher slope. Graph 1, increases steadily and then sharply increases; which fits C.
Description D has a constant and then a lower slope. Graph 3 increases fast but then flattens, which matches the slopes in the description.
C because it is the smallest lenghth
Answer:
Please read the explanation section.
Explanation:
They are called polymers because they contain many small, repeating sub-units bonded together.
In the chemical and biological science, some small molecules make a polymer, which is a molecule. A polymer is that kind of molecule, which is the result of binding up between smaller molecules called monomers.
A monomer is a type of polymer that is resulting from the assembly of many small units that are similar in nature. A monomer has a chemical compound with repetitive structural units. A polymer is a molecule made up of a chain of similar molecules, called
E.g., DNA, glycogen, amino acid, and proteins are polymers
The diagram for evolution of plants in the 4 stages is attached below.
<u>Explanation:</u>
The plants evolution has 4 main periods:
<u>A. 1st Period of Plant Evolution
</u>
About 420 million years ago, plants evolved from algae. Formation of cuticle was the first terrestrial adaption.
<u>B. 2nd Period of Plant Evolution
</u>
Abut 400 million years ago, the diversification of vascular plants came into being. The early vascular plants lacked seeds.
<u>C. 3rd Period of Plant Evolution
</u>
This was around 360 million years ago, that the seed evolved. The plants had seeds, but they did not have any covering, so they were called naked seeds. These plants were gymnosperms.
<u>
D. 4th Period of Plant Evolution
</u>
This was the evolution of flowering plants, happened around 130 million years ago (during early Cretaceous period). The flowering plants were called angiosperms.
Set point would be the correct answer i believe
