What else can I help you with?
All cells attached to the basement membrane but not all cells reach free surfaces is a description of what?
This describes the simple columnar epithelium tissue. In this tissue, all cells are attached to the basement membrane, but not all cells reach the free surface, as some may be buried below the apical surface of the tissue layer.
What are analogies for basal bodies?
Basal bodies are like the "anchors" of cilia and flagella, providing a structural base for their movement. They can be compared to the "roots" of a tree, stabilizing and supporting the growth of the structure. Alternatively, they are akin to the "foundation" of a building, ensuring stability and proper functioning.
How do you identify a psuedostratified epithelial tissue?
Pseudostratified epithelial tissue appears to be stratified due to the varying positions of the cell nuclei, but all cells are actually attached to the basement membrane. This type of tissue typically contains cells with cilia and can be found lining the respiratory tract. Observing the nuclei at different levels within the tissue can help identify it as pseudostratified.
What do cohesion surface tension and adhesion all have in common with reference to water?
Cohesion, surface tension, and adhesion are all properties of water that stem from its ability to form hydrogen bonds between water molecules. Cohesion refers to water molecules sticking to each other, surface tension is the result of the cohesive forces at the surface of water, and adhesion is the attraction of water molecules to other substances.
Where is the meristem located?
Groups of cells that are the source of new cells form tissue called meristem. Meristem cells aren't specialized, but when they divide, some of the new cells specialize into tissues. Areas of growth that lengthen the tips of roots and stems are called apical meristems. Lateral meristems, found all along woody roots and stems, increase the thickness of these plant parts.
Do epithelial tissues always exhibit polarity?
Yes, epithelial tissues typically exhibit polarity, with distinct apical and basal surfaces. The apical surface faces the external environment or a body cavity, while the basal surface is anchored to a basement membrane. This polarity allows for the specialized functions of epithelial cells, such as secretion and absorption.
All cells attached to the basement membrane but not all cells reach free surfaces is a description of what?
This describes the simple columnar epithelium tissue. In this tissue, all cells are attached to the basement membrane, but not all cells reach the free surface, as some may be buried below the apical surface of the tissue layer.
What is the basis of biologist to classify a specific epithelial tissue?
Epithelia are tissues consisting of closely apposed cells without intervening intercellular substances. Epithelia are avascular, but all epithelia "grow" on an underlying layer of vascular connective tissue. The connective tissue and the epithelium are separated by a basement membrane. Epithelium covers all free surfaces of the body. Epithelium also lines the large internal body cavities, where it is termed mesothelium.
What is the fuel for all energy-requiring processes in the body?
basal metabolism
What systems are lined with epithelial tissue?
Epithelia tissue lines all the body's surfaces and cavities.It is found on the surface of the body (skin) and lines the entire digestive tract, reproduction tract, respiratory track and lungs, excretory system, and endocrine system.Epithelia tissues that line the spaces of the body that are not directly open to the outside of the body such as the lymphatic system, blood system, and endocrine system is called endothelium. (Endothelia is a type of epithelia tissue by definition.)
Is a region that produces cells in a plant?
cork cambium, apical meristem, and vascular cambium. all the above
What is most common types of skin cancer?
There are three major types of skin cancer - basal cell carcinoma, squamous cell carcinoma and melanoma.
When do you check the apical pulse instead of radial pulse?
Apical pulse will never be less than the radial pulse. A radial pulse rate less than the apical rate is an example of a pulse deficit, and can be the result of a heart murmur, but the opposite will never occur.

What is a description of Pseudostratified ciliated epithelium?
Pseudostratified ciliated epithelium is a type of epithelial tissue found in the respiratory tract. It appears to be stratified due to the nuclei being at different levels, but all cells are in contact with the basement membrane. Most of the cells have cilia on their apical surface, which help in moving debris and mucus out of the respiratory system.
What is basal rate?
Your metabolism is the processing of food into energy that the body can use. Anything that you do, any activity at all, requires some degree of metabolism. But if you are not doing anything (other than resting) then your metabolism is at the lowest rate that it ever is. That is called the basal metabolic rate.
The body's rate of kilocalorie consumption needed to fuel all ongoing activities is called the?
basal metabolic rate. Its not basal metabolic rate because The basal metabolic rate (BMR) is the energy the body needs to perform only its most essential activities such as breathing and maintaining resting levels of organ function. Total Metabolic Rate because The total metabolic rate (TMR) is the rate of kilocalorie consumption needed to fuel all ongoing activities (involuntary and voluntary).
