The correct answer is B) Heavy metals such as mercury.

Explanation:

Heavy metals such as mercury or lead are denser than regular metals, this causes it is common for these metals to be found in the surface of Earth rather than in the air or atmosphere. Indeed, mercury and other similar metals are extracted from the Earth's crust and then used for different purposes. As a result of this, mercury ends up in the surface of Earth or in water sources which causes soil or water pollution. This means mercury is not a common source of air pollution; on the opposite other such as CFCs, nitrogen oxides and smog remain in the air and therefore are sources of air pollution.

Proteins that affect the structure of dna bound to histones without altering histone chemical structure are called:_______
slamgirl [31]

Proteins that affect the structure of dna bound to histones without altering histone chemical structure are called Non-histone protein.

The proteins that remain after the histones have been taken out are known as non-histone proteins. A large group of heterogeneous proteins referred to as non-histone proteins organise and compress the chromosome into higher order structures.
They play a crucial role in regulating processes such nuclear transport, steroid hormone activity, nucleosome remodelling, DNA replication, RNA synthesis and processing, and the transition between interphase and mitosis.
Scaffold proteins, DNA polymerase, Heterochromatin Protein 1, and Polycomb are examples of typical non-histone proteins. This classification area also includes a large number of other structural, regulatory, and motor proteins. Non-histone proteins can be acidic. Other than histones, many proteins have the ability to bind to DNA and change the shape of the chromatin by means of epigenetic processes.

Describe the path an egg from the ovary to the outside of the female body
Elis [28]
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
