How does dna replication occur?
Answer:
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.

What is coal used for
Answer: Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.

1. Which systems (2) are primarily responsible for movement of the body
Answer:
The correct answer is -muscular system and skeletal system.
Explanation:
The skeletal system and the muscular system work together to move the body or body parts. Different types of tissues form the muscular system that and their action on bones controls the movement of the body in vertebrates.
Tendons are tough muscles that attach with the bones and joints allow the movement by contraction of muscle that helps in moving bones from joint. Muscle normally acts by contracting and relaxing in pairs.
Which statements about geocentric model and heliocentric model are true? Select the two correct answers.
A. They both are models of the solar system.
B. They both show the position of Earth relative to the Sun.
C. They both show Earth at the center of the solar system.
D. They both show the Sun at the center of the solar system.
Answer: Your correct answer would be both A & B.
Explanation: A is the correct answer because both of these models are in fact models of our solar system. The geocentric model had Earth at the center of the solar system with all the other planets and sun rotating around us. The heliocentric model is the accepted model of our solar system today with the sun at the center and planets rotating in slightly elliptical fashions around it due to gravitational pull. B is also correct because as I just explained, both models position Earth in relativity to the sun though both models vary greatly. The aim of both of these models was to specify where Earth was exactly in the solar system. I hope this has been of use to you! Please do not hesitate to ask if you have other questions :)
The two correct statements about the geocentric and the heliocentric model are:
They both show the position of Earth relative to the Sun. They both are models of the solar system.The geocentric model
The geocentric model has the assumption that the earth is at the center of the universe. The sun and the planets are said to revolve around the earth in this model
The heliocentric model:
The heliocentric model has the assumption that the sun is at the center of the universe. The earth and the planets revolve around it.

Everything in the universe was created when the big bang occurred and the universe is expanding. So, the correct option is (A).
What is Big Bang Theory ?The Big Bang theory is an attempt to explain what happened at the beginning of our universe. Major discoveries in Astronomy and Physics have explained that our universe actually had a beginning. Before that moment there was nothing and after that jump there was something which is our universe.
According to the widely known theory, our universe sprang into existence as "singularity" which goes back around 13.7 billion years ago. Singularities are basically zones which flout our knowledge of physics. They are assumed to be present at the core of "black holes."
Black holes are regions of enormous gravitational pressure. The pressure is assumed to be so extreme that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of interminable density are called "singularities."
Thus, everything in the universe was created when the big bang occurred and the universe is expanding. So, the correct option is (A).

If DNA code consists of only four nitrogenous bases, how can it produce so much variety among
organisms of the same species?
Explanation:
I tnought this will help you
If DNA code consists of only four nitrogenous bases, still it produces so much variety among organisms of the same species with the help of Codons and amino acids sequences.
What do you mean by Nitrogenous bases?Nitrogenous bases may be defined as a molecule that contains nitrogen and possesses the chemical properties of a base. The nitrogenous bases that are found in DNA are Adenine (A), Guanine (G), Thymine (T). and Cytosine (C). Uracil (U) is present instead of Thymine in RNA.
There is a total of 4 nitrogenous bases that are found in DNA and RNA. Each codon codes with the help of three nitrogenous bases. So, total variations = [tex]4^3[/tex] = 64.
But there are only 20 amino acids that are commonly known. Some codons are stop codons, they do not code for any amino acids. While some codons code for the same amino acids.
Therefore, If DNA code consists of only four nitrogenous bases, still it produces so much variety among organisms of the same species with the help of Codons and amino acids sequences.

A(n)\ is an area of the planet that shaves similar conditions of climate, fauna (animal life), flora (plant life) and geography .
1.biome
2.environment
3.habitat
4.ecosystem
Answer: A BIOME is an area of the planet that shaves similar conditions of climate, fauna (animal life), flora (plant life) and geography . The correct option is 1.
Explanation:
BIOME is defined as large natural terrestrial ecosystems which shares similar conditions of climate and consists of plants and animals that equally have common characteristics with their environment. The word terrestrial is used because plants form the bulk of the community in an ecosystem. The type of vegetation in a biome is largely determined by climatic factors, especially rainfall and temperature. Regions throughout the world which have similar climates have similar biomes. This causes zones of different biomes to occur from the equator to the Arctic and to the Antarctic. For example,
--> in equatorial and tropical areas where temperature is high all the year round tropical forests occur;
--> in temperate regions coniferous and deciduous forests occur;
--> while treeless plains (tundra) are found in the cold arctic regions.
Climates also changes with height above the sea level.

If there weren't alleles for different traits, but rather only one version of a gene for different traits, how would humans be different?
Answer:
Humans would look exactly alike
Explanation:
An allele which is a variation of a gene which expresses a particular trait(Phenotype).
For example, if humans have a gene for eye color but has different alleles for the color being black or brown for example, their phenotypes are different since the alleles are different.
But, if the alleles for the eye color are all the same, the eye color and every other phenotype would be the same. So, there would be no variations in eye color, height, color of skin etc. So, all humans would thus look alike having one set of genes for the different traits.
