The number of fossils found, the fact that fossils are oftentimes just a cast/mold of the organism with no real remains, and no interbreeding.

As time moves forward, we still strive towards better methods to answer questions about extinct organisms.

Oxana [17]

Explanation:

All vital organs begin to lose some functionality as one ages during adulthood. Aging changes occur in all cells, tissues and organs of the body and affect the functioning of all body systems.

The living tissue is made up of cells. There are many different types of cells, but they all have the same basic structure. Tissues are layers of similar cells that fulfill a specific function. Different types of tissues group together to form organs.

There are four basic types of tissue:

The connective tissue supports the other tissues and joins them. This includes bone, blood and lymphatic tissue, in addition to the tissues that provide support and structure to the skin and internal organs.

The epithelial tissue provides coverage for the superficial and deeper layers of the body. The skin and lining of the ducts inside the body, such as the gastrointestinal system, are made of epithelial tissue.

Muscle tissue includes three types of tissue:

Striated muscles, such as those that move the skeleton (also called voluntary muscles)

Smooth muscles (also called involuntary muscles), such as the contents in the stomach and other internal organs

Myocardium, which makes up most of the wall of the heart (also an involuntary muscle)

Nervous tissue is composed of nerve cells (neurons) and is used to carry messages to and from different parts of the body. The brain, spinal cord and peripheral nerves are composed of nerve tissue.

Given what we know, we can confirm that if a cancer medicine wishes to stop cellular division, it must target the Centrioles of a cell.

<h3>What are the Centrioles of a cell?</h3>

The centrioles are cylinder-shaped organelles made up of microtubules.
Their function is to organize the contents of the cell before cellular division.
This is done to ensure that once the cell divides, its contents are split evenly to each daughter cell.
They also play a role in initiating the cellular division process.

Therefore, given the role of the centrioles in organizing the contents of the cell for cellular division, as well as initiating the first part of cell division, we can confirm that in order for a cancer medicine to stop cell division, it must target the centrioles.

The right answer is: <span>organelle, cell, and tissue

<span>Muscle is a soft tissue, found in animals. Composed of muscle tissue and connective tissue (+ blood vessels + nerves). The muscle cells (a component of the muscle tissue) contain actin and myosin protein filaments that slide on each other, producing a contraction that changes both the length and shape of the cell.
</span></span>The muscle cells, like other cells, consists of a plasma membrane containing a cytoplasm, which is formed of an aqueous solution (Cytosol) in which there are many biomolecules such as proteins and nucleic acids, organized or not in the context of organelles.<span>
