The mass of an atom is contained primarily in its _____. A. Electron Shell B. Nucleus C. Proton D. Size

Answers

Answer 1

Answer: The mass of the atom is contained mainly in the nucleus itself. The nucleus is composed of a number of protons and neutrons which are positively charged and neutrally charged sub particle components. The nucleus are surrounded by electrons.

Answer 2

Answer: The mass of an atom is contained primarily in its NUCLEUS.
An atom is made up of three sub particles, which are proton, neutrons and electrons. The proton and the neutrons are located in the nucleus of the atom while the electron are located outside the nucleus where they move about in continuous motion around the nucleus. The proton and the neutrons, which are located in the nucleus have the same relative mass of 1, which has been estimated to be about 2,000 times bigger than that of the electron, which has a relative mass of 0.0005. This shows that, the mass of an atom is located primarily in its nucleus.

Rephrase the law of conservation of mass in your own words

Answers

the mass of matter remains the same even when undergoing a chemical change because matter can neither be created or destroyed

The law of conservation of mass basically says that nothig can be "created" or "destroyed" but that thigs just under go transformations and change into something else. For example, take a pile of wood. If light it on fire it doesnt disappear, i have just changed it into ash and thermal energy.

How does gravitational electrical and magnetic forces act on a maglev train

Answers

The gravitational force is being felt as the Earth pulls the train downwards using the two forces. The coils that provide the forces releases an electrical current which makes an electromagnetic field. It repels the materials with an equal force that goes up as well.

Which characteristic defines all dichotomous keys?Each key is a series of statements.
Each key is organized as a table.
Each key is organized as a flowchart.
Each key is a mathematical formula.

Answers

Answer:

c. Each key is organized as a flowchart.

Explanation:

A dichotomous key is a device that enables users to recognise natural world objects, such as wildflowers, trees, reptiles, mammals, fish and rocks. it used for the Identification whereby groups of species are frequently divided into two categories with increasing sequential division, more information on the basic characteristics of a particular organism is released.

Dichotomous keys are represented in two ways including either as descriptive representation in which a series of paired statements arraged in a numbered sequence or as a branching flowchart (diagrammatic representation).

Hence, the correct option is c.

Answer:

Each is a series of statements

Explanation:

If you have seen dichotomous keys you see that there are tables and flo charts. Notice each answer choice says "Each" but there are many different kinds. Dichotomous keys are definitely not mathematical formulas. SO you can infer it is a series of statements. Also I took the test

For any given gene, what ultimately determines which dna strand serves as the template strand?

Answers

The answer is the base sequence of gene's promoter.

DNA is a two-stranded helix. One strand is called a template strand, the other one is called a coding strand. The template strand is copied into mRNA, and the coding strand is complementary to the template strand. RNA polymerase, an enzyme responsible for transcription, has to recognize the right strand before transcription begins. So, it recognizes one or more short sequences on the coding strand. This is the base sequence of gene's promoter. Thus, the complementary strand is the template strand.
