b. the axis has a slight tilt
Based on the structure and arrangements of nucleotides in the <u>DNA </u>molecule, the molecule is an information molecule. It stores instructions and is read to produce proteins that direct cellular reproduction, produce new cellular components, and initiate cellular reproduction.
<h3>Describe DNA.</h3>
Deoxyribonucleic acid is referred to as a DNA Trusted Source. It includes units known as nucleotides, which are biological building blocks.
For most other organisms in addition to humans, DNA is an essential chemical. Our genes and genetic material, which are what gives us our individuality, are both found in our DNA.
<h3>What is the DNA's structure?</h3>
A DNA molecule is created from a group of nucleotides. There are three components in each nucleotide:
- a phosphate group
- a sugar
- a base of nitrogen
The name of the sugar in DNA is 2-deoxyribose. The "backbone" of the DNA strand is made up of these sugar molecules that are in alternation with phosphate groups.
In a nucleotide, each sugar is joined to a nitrogen base. Nitrogen bases come in four main varieties in DNA. They consist of:
- adenine (A)
- cytosine (C)
- Thymine(T)
- guanine (G)

Answer:
A. Those continents were once a part of one supercontinent.
Explanation:
This so called supercontinent is called Pangea, which existed during the late Paleozoic and early Mesozoic eras, and assembled approximately 335 million years ago, which began to break apart about 175 million years ago.
Answer:
The correct answer is -
differences: color, brightness, temperature, size, and mass
similarities: They are balls of gas, mostly hydrogen and helium
Explanation:
Stars look mostly the same from anywhere or any place and tough to differentiate or distinguish one from another. Star can be different on the various ground even they look similar from far away.
Stars can be of various colors from red to blue and brightness can be different as well, color depends on temperature, and brightness depends on the size of the star.
Stars are grouped by the size that ranges from dwarf to supergiant. The temperature of the stars also varies which affects the color and brightness as well.
Stars are the big balls of gases composed of mainly helium and hydrogen all are always under a nuclear reaction.
