The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.

LekaFEV [45]

Answer:D.D.) Suspend the cells in liquid agar culture and monitor which culture continues to grow.

Explanation

Options A-C are correct except D.

→Increase in Telomere length is indicative of abnormal growth, cancer cells can reactive  telomerase to increase cell's length.

→Once a monolayer is reached; this a stage of  a complete normal cell division , a cell that goes beyond this stage must be mutated. assuming all other factors are constant .

Uncontrolled cell division is an indication of virulent growth in mutated cells.

<u>Cancer cell requires a ,medium of  living host to thrive, alga medium will not support growth for carcinoma cells -the correct answer. </u>

<u></u>

Completed Que.

:Imagine that you are a graduate student working in a cancer lab. You accidentally mix unlabeled tubes of carcinoma cells with tubes of normal epithelial cells. Which of the following is NOT a possible strategy to allow you to distinguish which tubes contain carcinoma cells?

A.)Monitor telomere length over time during multiple cell divisions.

B.) Plate the cells in culture and look for the culture that stops dividing once a monolayer is reached.

C.) Monitor the rate of cell division.

D.) Suspend the cells in liquid agar culture and monitor which culture continues to grow.

1. The right answer is electron.

The electron, one of the components of the atom with neutrons and protons, is an elementary particle that has an elementary charge of negative sign. It is fundamental in chemistry because it participates in almost all types of chemical reactions and is an essential element of the bonds present in molecules.

The mass of an electron is 9.109 × 10-31 kg. The electron is about 2000 times lighter than the proton and neutron in the nucleus. The masses of the proton and the neutron are almost identical (10-27 kg).

2. The right answer is rapidly moving electrons.

The chemical, physical and electrical properties of an atom are related to the number of protons in the nucleus, which determines the number of electrons in the electron cloud.

The electron cloud is formed of electrons rotating at high speed around the nucleus in very complex trajectories. The electronic cloud is composed of electrons so its electric charge is always negative.

3. The right answer is Atoms of the same element can have different numbers of neutrons.

Isotopes (of a certain chemical element) are called the nuclides sharing the same number of protons (characteristic of this element), but having a different number of neutrons.

So what characterizes an element is the number of protons.

By extension, isotope is often called a nuclide characterized by its number of protons Z and its number of neutrons N (or its mass number A = Z + N), but without distinction regarding its spin or energy state.

4. The right answer is 8.

The atomic number (Z) is the term used in chemistry and physics to represent the number of protons in an atom. An atom can be schematized as a first approach by a compact agglomeration (atomic nucleus) of protons (p +) and neutrons (n), around which circulate electrons (e-).

5. The right answer is 18.

The relative atomic mass (or atomic weight) is the mass of an atom in particular or a chemical element in general (in which case an isotopic mixture is envisaged) expressed as a multiple of a reference elementary mass that wants to be close to that of a single nucleon. Indeed the mass of an atom is proportional in first approximation to the number of its nucleons (protons and neutrons), said number of mass.
