What are Four Examples of cells and what they do?
a stem cell... and it is a general cell that can change into a specific cell a red blood cell... it carries oxigen to parts of the body a white blood cell... it attacks and destroys some infections a skin cell... it defends the body from attacks on the outside....
Which kind of cell in the human body would have more mitochondria- a muscle cell or a skin cell?
Muscle cells have more mitochondria because they require more energy to contract than skin cells.
How many chromosomes doe s a human body cell have?
46 in a human body cell. 23 in the sex cell e.g. sperm and egg cell (gametes) when they combine you end up with 46 again.
Where is the cell wall located in a human body?
Cell walls are not found in human cells. Instead, human cells are surrounded by a cell membrane, also known as the plasma membrane, which helps control the movement of substances in and out of the cell.
What cell of the human body has more mitchondria a muscle cell or skin cell?
A muscle cell
What the longest cell in the human body?
Nerve cell is the longest cell in human body.
The longest cell in human body?
The Longest cell in the human body is the nerve cell.
What is the name for a regular human body cell?
Simply a "Cell", in general, anyway... Eukaryotic cell is the name for a regular human body cell.
The ability of a muscle to contract and relax is dependent on the flow of what?
The ability of a muscle to contract and relax is dependent on the flow of calcium ions. When a muscle is stimulated, calcium is released from storage sites within the muscle cell, allowing the muscle fibers to slide past each other and generate force. Removal of calcium from the muscle cell leads to relaxation of the muscle.

What is the smallest part of a human body?
the human cell
Which cell can contract and relax why?
Muscle cells can contract and relax due to their unique structure and function. They contain specialized proteins, such as actin and myosin, that interact to generate force and movement. When stimulated by nerve impulses, these proteins slide past each other, causing the muscle to shorten (contract) and then return to its original length (relax) when the stimulus is removed. This ability is essential for various bodily movements and functions.
Which type of cell in the human body lacks a cell nucleus?
Red blood cells, also known as erythrocytes, lack a cell nucleus in the human body.
Which kind of cell in the human body would have more mitochondria- a muscle cell or a skin cell?
Muscle cells have more mitochondria because they require more energy to contract than skin cells.
What is the smallest cell in the human body but isn't human?
Bacteria
What is the shortest cell in human body?
There are a number of contenders for the position of smallest cell in the human body. The head of the sperm is on average 5 to 6 micro meters. The flagellum is up to 50 micrometers long. Also some says Granule Cell of the Cerebellum is the smallest cell of the human body it is approximately 4um to 4.5um in size. The size of the RBC also found as around 5 micrometers. In terms of volume most of the scientists suggest that sperm is the smallest cell.
