Answer:

Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process (see the 1ˢᵗ law of thermodynamics).

Shkiper50 [21]

The sequence with the correct word in place would be DNA --> Gene --> Chromosome

<h3>Organization of genetic information</h3>

The basic unit of genetic information is the gene.

Genes are made up of a base sequence of DNA.

Genes are organized into structures known as chromosomes.

Thus, DNA --> Gene ---> Chromosomes

Calculate the mass defect for oxygen-16 given this data. Round to the 5es001-1.jpg decimal place. mass of an oxygen-16 atom: 15.

Naya [18.7K]

Answer:

Explanation:

Given parameters:

Mass of oxygen atom = 15.994914amu

Mass of a proton = 1.00728amu

Mass of a neutron = 1.00866amu

Unknown:

Mass defect = ?

From the periodic table, the number of the elementary particles in a neutral Oxygen atom is given below:

Number of protons = 8

Number of neutrons = 8

Number of electrons = 8

Solution

The mass defect examines the difference between the actual mass of an atom and sum of masses of the nucleons.

The mass of an atom is concentrated in the nucleus which contains protons and neutrons. Electrons have little to no weight compared with the nucleons.

To calculate the mass defect, we first know the mass of the nucleons first:

1 proton has a mass of 1.00728amu

8 protons will weigh: (8 x 1.00728)amu = 8.05824amu

For the neutrons:

1 neutron has a mass of 1.00866amu

8 neutrons will weigh: (8 x 1.00866)amu = 8.06928amu

Mass of the nucleons = mass of protons + mass of neutrons

= 8.05824amu + 8.06928amu

= 16.12752amu

The mass defect = mass of the nucleons - mass of the atom

= 16.12752amu - 15.994914amu

= 0.132606amu ≅ 0.13261amu to 5 decimal places

A scientist is comparing the outer structure of an onion cell, structure X, to the outer structure of a human skin cell, structu

hammer [34]

Answer:

Structure X is only found in plant cells, and structure Y is found in plant and animal cells.

Explanation:

The structure found on the outside of the onion cell is the cell wall, which is specific to plants. The structure found on the outside of the skin cell is the cell membrane, which is found on all cells.

Structure X is not living, and structure Y is living. - this is false, both animal and plant cells are living.

Structure X can be found in some human cells, and structure Y can be found in some plant cells. - this is false, the opposite is true.

Structure X is only found in plant cells, and structure Y is found in plant and animal cells. - this is true structure X is the plant cell wall, and structure Y is the cell membrane

Structure X is semipermeable, and structure Y is selectively permeable. Semi-permeable and selectively permeable are essentially the same thing - it means the barrier allows some substances to pass through but not others.
