A log has a density of .8 g/cm³. This log will _______ in freshwater, which has a density of 1.0 g/cm³ .
m_a_m_a [10]
The log will float on the water because his density is lower than the liquid, so it will stay at the top due to Archimedes' principle.

<span>Archimedes' principle is a physical law that describes the upward force (the vertical thrust) experienced by any body immersed in a fluid (liquid or gas). This force is strongly related to the density of both the fluid and the body.
</span>
You can try the experience at home, by using an object that has a lower density than the water like the sunflower oil, you will see that it will stay at the top of the water too.

For what purpose is mitochondrial genomics used
bezimeni [28]

<span>The mitochondria are famously known as the powerhouse of the cell since it is the one that gives the cells energy that is also used by the human being.  This energy conversion is called oxidative phosphorylation. Mitochondria are found in eukaryotic cells, including humans.  These organelles also had its own genome, or what we called as DNA which is known as mitochondrial DNA, or mtDNA which is present in the mitochondrial matrix.  The role of mtDNA or mitochondrial DNA is to convert the energy from food into any other forms that it thinks the cell can use.  It is containing 37 genes which are all necessary for a normal mitochondrial function.</span>

A plant's stem _____.
Natali5045456 [20]

Answer:

All the above

Explanation:

A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports fluids between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue.

Stems have four main functions which are:[1]

Support for and the elevation of leaves, flowers and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits.

Transport of fluids between the roots and the shoots in the xylem and phloem(see below)

Storage of nutrients

Production of new living tissue. The normal lifespan of plant cells is one to three years. Stems have cells called meristems that annually generate new living tissue.

The INDEPENDENT VARIABLE:
klemol [59]

Answer:

B. Is what the scientists manipulate in the experiment.

Explanation:

The Independent variable is not dependent, or doesn't rely, on another variable in the experiment. So, it would make the most sense that they would manipulate the Independent so that they can watch and see how the dependent variable reacts to the manipulation, or the change, in the independent variable.
