Which Statement Best Explains Why Muscle Cells And Skin Cells Do Not Look And Act The Same?

Terms in this set (3) In your body why do muscle cells and skin cells look and behave differently? Their genes are being expressed differently.

Why do muscle cells and skin cells do not look and act the same?

Skin cells and muscle cells will need to turn “on” the genes that help use energy – all cells need energy to live! … Epigenetic marks are why different cells in your body look and act differently even though they all have the same DNA: they’re reading different parts of your DNA’s instructions.

Why do muscle cells act differently than skin cells?

Skin cells are specialized to be quickly shed and replaced and do not have much mitochondria (which helps produce energy). Muscle cells conversely have lots of mitochondria because they need energy to produce movement.

Why do muscle cells and skin cells look different and have different shapes?

Bone cells muscle cells and skin cells look different because (C) different genes are active in each kind of cell. Every cell in the body has the same number and type of genes as every other cell.

How are skin cells and muscle cells different?

Skin cells are the epidermal cells which cover all the organs of the body by forming a tissue called the skin. … Muscle cells have many mitochondria which provide lot of energy during contraction and relaxation of the cells. Muscle cells form structures called as muscles.

What causes your muscle cells and your skin cells to have such different structures and functions?

All cells have the same genes but not all make the same proteins. What causes your muscle cells and your skin cells to have such different structures and functions? … All cells have the same DNA/genes BUT ALL CELLS ARE NOT THE SAME Expression of those genes is what makes somatic cells differ from one another.

Which best explains why muscle is considered a tissue?

Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.

Why do your cells not all look and function the same?

Different cells in a multicellular organism may express very different sets of genes even though they contain the same DNA. The set of genes expressed in a cell determines the set of proteins and functional RNAs it contains giving it its unique properties.

Why do different cells look different?

Cells have different shapes because they do different things. Each cell type has its own role to play in helping our bodies to work properly and their shapes help them carry out these roles effectively.

Why do some of these cells look so different from each other?

In order for cells to become whole organisms they must divide and differentiate. Cells divide all the time. … All the cells contain the same genetic material and all of them are from one original cell that started as a fertilized egg but they look different and act different from one another. This is differentiation.

Why is it that some cells are muscle cells Some cells are nerve cells and other cells are skin cells?

Why is it that some cells are muscle cells some cells are nerve cells and other cells are skin cells? Different genes are expressed in different cell types. … Chromosomes line up in the middle of the cell. Chromosomes move apart.

Which explains why muscle cells are different from blood cells despite having the same DNA?

Which best explains why muscle cells are different from blood cells? … Different genes are activated in muscle cells than in blood cells. Muscle cells experience different environmental influences than blood cells. Muscle cells are produced by the brain but blood cells are produced by the heart.

Do skin cells and muscle cells have the same genes?

We learned in biology class that every cell in the body has the same DNA. Whether a heart cell skin cell or muscle cell—they all read from the same genetic blueprint.

Do muscle cells and nerve cells have the same proteome?

Some proteins are the same in most cells: muscle cells and nerve cells need to build common structures like mitochondria. But there are also unique ingredients in both cell types: a muscle cell needs special proteins that let the muscle cells move during contraction.

Do muscle cells use more energy than skin cells?

There are more mitochondria in muscle cells than there are in skin cells. … Cells that are more active and/or move more will require a greater energy produced via cellular respiration. Therefore cells that are more active usually contain more mitochondria than cells that are not as active.

What statement applies to tissues?

Which statement applies to tissues? Cells within a tissue cooperate and each tissue has a specific function.

Why is it important for a cell to regulate protein production?

In general why is it important for a cell to regulate protein production? The cell needs enough protein for its needs but at the same time if there are too many the system may be overwhelmed or energy could be wasted.

What is gene expression PDF?

Gene expression is the process by which. information from a gene is used in the synthesis of. a functional gene product. These products are often. proteins but in non-protein coding genes such as.

Which term best describes a muscle cell?

Since muscle cells are called muscle fibers the myofibrils are the smaller fiber-like organelles within a muscle fiber.

Which statement best explains why nerve cells and red blood cells have structural differences?

A determine the differences in ages of a set of people B identify how closely two individuals are related C determine how effective certain medications are D identify different blood types Biology Page 4 Page 5 2 The diagram illustrates the activity of vesicles during a cellular process.

What cells make up muscle tissue?

Muscle cells commonly known as myocytes are the cells that make up muscle tissue. There are 3 types of muscle cells in the human body cardiac skeletal and smooth. Cardiac and skeletal myocytes are sometimes referred to as muscle fibers due to their long and fibrous shape.

Do all cells have the same function explain?

Cells have many parts each with a different function. Some of these parts called organelles are specialized structures that perform certain tasks within the cell.

Why are all cells not the same?

This is because all of the cells in our bodies start from a single fertilized egg. With few exceptions all cells in a person’s body have the same DNA and genes. As cells divide and grow different genes are expressed resulting in different cell types.

Why do cells that belong to the same multicellular organism have a different structure and function?

The cell types in a multicellular organism become different from one another because they synthesize and accumulate different sets of RNA and protein molecules. They generally do this without altering the sequence of their DNA. … Often one of these individual cells can regenerate an entire adult plant (Figure 7-2B).

Why do different cells make different proteins?

All the cells of higher organisms have the same DNA but not the same proteins. Each type of specialised cell that forms a tissue has its own pattern of gene expression and consequently it contains a particular set of proteins that determine its function.

Why does the body need different types of cells give some examples of different cells?

Different cells have different jobs to do. Each cell has a size and shape that is suited to its job. Cells that do the same job combine together to form body tissue such as muscle skin or bone tissue. Groups of different types of cells make up the organs in your body such as your heart liver or lungs.

In what ways do cells differ from each other quizlet?

Cells differ from each other by their functions/specialization and their organelles.

Why do your heart cells brain cells eye cells and skin cells all have the same genes?

It sounds like you are already well aware of the fact that every cell in our body has the same set of genes. This is because all of the cells in our bodies start from a single fertilized egg. That first cell divided over and over again until a new baby was made.

How can nerve cells and muscle cells differ in structure and function?

Hint: Muscle cells are found specifically in muscles and can be either voluntary or involuntary. Nerve cells are functional units of the nervous system that are always involuntary.
…
Complete answer:

Muscle Cells (Myocytes)	Nerve Cells (Neurons)
Muscle fibers or cells can divide.	Nerve fibers or cells cannot divide.

What do nerve cells and muscle cells have in common?

Nerve cells and muscle cells are excitable. Their cell membrane can produce electrochemical impulses and conduct them along the membrane. … The origin of the membrane voltage is the same in nerve cells as in muscle cells. In both cell types the membrane generates an impulse as a consequence of excitation.

Why is it important for cells to grow before cell division?

It is important for cells to divide so you can grow and so your cuts heal. It is also important for cells to stop dividing at the right time. If a cell can not stop dividing when it is supposed to stop this can lead to a disease called cancer. Some cells like skin cells are constantly dividing.

How do blood cells interact with muscle cells?

When oxygenated blood reaches muscle cells the bond between oxygen and hemoglobin molecules loosens. When the red blood cells pass single file through the tiny capillaries that surround muscle cells (figure 3.2) oxygen molecules are released from hemoglobin and diffuse into the muscle cells.

What is the main difference between muscle cells and nerve cells?

The main difference between muscle cells and nerve cells is that muscle cells are responsible for the contraction and relaxation of muscles whereas nerve cells are responsible for the coordination of the functions of the body through the transmission of nerve impulses between the body and the central nervous system.

Do muscle cells and nerve cells contain different DNA?

Each cell contains all of the organism’s genetic instructions stored as DNA. … For example a muscle cell uses the DNA that specifies the muscle apparatus whereas a nerve cell uses DNA that specifies the nervous system.
