Answer:

A-They allow scientists to make predictions

Explanation:

Scientific models aid scientists in performing experiments by allowing them to better understand their subject. This rules out B. C and D simply do not make sense, as all good experiments should generally use data to prove the validity of their points and there’s no real way to prevent criticism. Hope it helps :)

Everything in the universe was created when the big bang occurred and the universe is expanding. So, the correct option is (A).

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).

Explanation:

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.These proteins provide structure and support for cells. On a larger scale, they also allow the body to move.

Answer:

It has 24 pairs and 48 number of chromosomes.

Explanation:

The Chimpanzee's diploid number of chromosome is 24 pairs instead of 48 because of the resemblance with the human cell that have 23 pairs of chromosome. The Chimpanzee has 24 pairs of chromosome or another words we can say that chimpanzee has 48 number of chromosomes not pairs. Humans have 23 pairs whereas apes have 24 pairs of chromosome. The theory suggested about this close number of chromosomes is that at some point two ape chromosomes fused to make a single human one.

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 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.

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.

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.

Answer: c

Explanation:

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.

Explanation:

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.
