Structures that move things on the surface of some human cells include cilia and flagella. Cilia are small, hair-like projections that beat in coordinated waves to move substances along the cell surface, while flagella are longer and whip-like, primarily used for the locomotion of sperm cells. Both structures are composed of microtubules arranged in a specific pattern and are important for various cellular processes, including the movement of mucus in the respiratory tract.
What else can I help you with?
What cellular structures are found in the epidermal cells of humans but not in epidermal cell of leaves?
Melanocytes, which produce melanin for skin pigmentation, are found in human epidermal cells but not in leaf epidermal cells. Additionally, human epidermal cells contain structures like Langerhans cells for immune response, which are not present in leaf epidermal cells.
A protein on the surface of HIV can attach to proteins on the surface of healthy human cells. theses attachment sites on the surface of he cells are known as?
The attachment sites on the surface of healthy human cells that allow HIV to bind are known as CD4 receptors. Additionally, HIV also requires co-receptors, such as CCR5 or CXCR4, to facilitate entry into the cells. This interaction is crucial for the virus to infect the host cells and propagate the infection.
A protein on the surface of HIV can attach to what proteins on the surface of healthy human cells?
HIV's surface protein, gp120, can attach to CD4 receptors on healthy human cells. This interaction allows HIV to enter and infect the cell by binding to the CCR5 or CXCR4 co-receptors on the cell surface.
Are bacteria cells the same as human skin cells?
No, bacteria cells are prokaryotic cells, meaning they do not have a nucleus or membrane-bound organelles, while human skin cells are eukaryotic cells with a nucleus and organelles. Additionally, bacteria cells are much smaller in size compared to human skin cells.
Is the human nerve cells living things?
Yep. Every part of the human body is living. Your hair, nails, cells, etc.
Human cheek cells are part of what organ system?
Human cheek cells are part of the integumentary system, which includes the skin and its associated structures. Cheek cells are found on the surface of the skin lining the inside of the cheeks.
Are cells the same in the human body?
There are different types of cells, but the structures are basically same, with similar organelles and other structures.
How are cells and the human body alike?
Cells form the human body. Both things are alive.
Does the human eye shed skin?
Yes, the human eye can shed skin cells from the surface of the cornea. These cells are constantly sloughed off and replaced with new cells to maintain a healthy ocular surface.
What is good for the human cells?
There are many different things that are good for human cells. These things include food and many different vitamins and minerals.
What cellular structures are found in the epidermal cells of humans but not in epidermal cell of leaves?
Melanocytes, which produce melanin for skin pigmentation, are found in human epidermal cells but not in leaf epidermal cells. Additionally, human epidermal cells contain structures like Langerhans cells for immune response, which are not present in leaf epidermal cells.
What packages things in the human body?
cells... but inside the cells, the Golgi apparatus.. think of it as a post office... it packages and ships things out of a cell into the human body
Different between human cell and animal cell?
Human and animal cells have the same basic structures, yet human cells usually have different jobs pertaining only to that particular cell.

How do antibiotics work to target bacteria without causing harm to the surrounding human cells?
Antibiotics work by targeting specific structures or processes in bacteria that are essential for their survival, such as cell wall formation or protein synthesis. These structures or processes are not present in human cells, so the antibiotics are able to selectively kill the bacteria without harming human cells.
What does the Periosteum supply the bone cells with?
The periosteum porects the bone from surrounding structures, anchors blood vessels and nerves to the surface of the bone, and provides stem cells for bone width growth and fracture repair. (McKinley, Michael. Human Anatomy. McGraw-Hill. 2008. p151)
