Answer:

The first thing to do is carbon dating, to find out how old these bones are.

Explanation:

Carbon dating is done by a technique called "Carbon-14" and is performed when a skeleton is found to determine how many years have passed since the death of that organism. This technique allows the years of this skeleton to be counted, because living beings are rich in carbon molecules in their composition. When an individual dies, the carbon-14 molecule in its composition dies too, so dating that molecule allows you to date how long that organism has been dead.

omeli [17]

Answer:

A. red blood cells containing malaria

Explanation:

Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite Plasmodium sp., which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.

When they multiply within the red blood cell, they burst the red blood cell open, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.

Malaria is a deadly illness, causing harm to its hosts, and in many cases death. Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.

Fudgin [204]

Answer:

True.

Explanation:

Lymphatic system is one of the most important system of the body that carries the lymph fluid towards the heart. This system plays an important role in the body immune system.

The pressure in the lymph vessels are very low. The movement of adjacent tissue in the lymph is important to propel it through the lymphatics. The intrinsic or extrinsic compression are important for the lymph flow.

Thus, the correct answer is True.

The value of the dependent variable is based upon changes in the values of the independent variable.

<h3>What is the dependent and independent variable?</h3>

The term independent variable has to do with the variable that is being intentionally manipulated in an experiment. The dependent variable is the variable that changes in value as the independent variable is manipulated.

Now, the question is unclear however, we do know that in an experiment, the value of the dependent variable is based upon changes in the values of the independent variable.
