The options attached to this question are given below:

A. Their masses are always equal.

B. Each element always contributes the same number of atoms.

C. Atoms of different elements always combine in the same way.

D. Their volumes are always equal.

ANSWER

The correct option is C.

John Dalton was an English Chemist, he was the one who proposed  the statements that are called Dalton's atomic theory. The theory  is made up of five main points, they include the following:

1. All matters are made up of atoms.

2. Atoms of the same elements are identical.

3. Atoms of different elements vary in size and mass.

4. Compounds are formed when elements combined in whole ratios.

5. A chemical reaction result in rearrangement of the atoms in the reactants to form products.

Dalton atomic theory has been extensively revised.

In science why is it important to have more than one piece of evidence to support your claim?
My name is Ann [436]

Answer:

It is important to have more than one piece of evidence to make sure that the evidence is actually evidence. Or in other words, that the evidence is proven true. With only one piece of evidence, you can't be fully sure if calculations were correct, if the source was trustworthy, etc.

Multiple evidence is kinda like double checking math problems. If you don't do it, you can't be 100% certain the answer is correct.

Suppose a point mutation, such as a change from an adenine to a guanine, occurs in the genome of a human sperm cell. The mutatio
yulyashka [42]

Answer:

B. The mutation results in a new, dominant allele

C. The mutation occurs in a gene that controls development and alters differentiation of a cell type during development.

D. The mutation occurs in a codon and alters the function of the final protein

Explanation:

All the above things will change the <u>ultimate expression</u> or phenotype by altering the proteins. Choices B, C, and D will all change the outer functioning.

Choice A only affects the rate of transcription, so it may go faster or slower, but the end product will be the same.

This part that doesn't look like it's one of the choices ("The mutation occurs in a portion of an intron not responsible for exon splicing.") would not affect phenotype, because introns are removed before the RNA is sent out.

Choice E says that the amino acid sequence is unchanged, meaning the protein final product will be the same and the expression will not change.

Explain the relationship between crossing over and genetic variation
Semmy [17]

A variation is a reference to the differences or deviations, such as the structure and form, as for crossing over is the exchange of genetic material between the non-sister chromatids of the homologous chromosomes during meiosis.

Describe how a food differs from a food web and explain what the arrows on the food chain show
Vsevolod [243]

Answer:

A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.
