What cellular organelle is a projection that moves substances onto epithelial surfaces?
Cilia are cellular projections that move substances along the surface of epithelial cells. They beat in a coordinated manner to propel mucus and other substances across the epithelial surface, aiding in functions such as mucus clearance in the respiratory tract.
What system for mapping the round earth on a flat surface called?
A map projection is a way to represent the curved surface of the Earth on the flat surface of a map.
An adaptation to increase the surface area of a part of a cell that is involved in cellular respiration?
Microvilli are small protrusions found on the surface of cells, particularly in the intestines and kidneys, that increase surface area for absorption. These structures contain enzymes and transport proteins important for cellular respiration.
What is the sharp projection from the surface of a bone?
A sharp projection from the surface of a bone is called a process. Bones can have different types of processes, such as a spinous process, which is a sharp, pointed projection; or a tuberosity, which is a large, rounded projection. Processes serve as attachment points for ligaments and tendons.
Is a higher surface area to volume ratio is more efficient for cellular activity?
Yes, a higher surface area to volume ratio is more efficient for cellular activity because it allows for faster exchange of substances with the environment, such as nutrients and waste products. This is important for processes like cellular respiration and nutrient uptake.

Which organelle is involved with cellular transport?
The endoplasmic reticulum (ER) is the organelle primarily involved in cellular transport. It plays a key role in the synthesis and transport of proteins and lipids within the cell. The rough ER, with ribosomes attached to its surface, is particularly involved in protein synthesis and trafficking.
Whiplike cellular extensions that move substances along the cell surface are called?
Cilia are whiplike cellular extensions that move substances along the cell surface. They are found in various cell types and are important for processes such as maintaining airway clearance and moving fluids in the body.

What is a characteristic of mitochondria that suggests that they might have evolved from free living bacteria?
The plasma membrane of a mitochondrion, forming the surface of this organelle, is the site of many important steps of cellular respiration.
What is the earths flat surface called?
Projection

What developable surface is used to create the Mercator Projection?
A cylinder is used to create the Mercator Projection. The Earth's surface is projected onto the cylinder, which is then unrolled to create a flat map. This projection results in distortions in the polar regions.
What organelle has a lot of surface area?
The endoplasmic reticulum (ER) has a lot of surface area due to its membrane structure, which folds and extends extensively throughout the cell. This large surface area allows for important cellular processes such as protein synthesis and lipid metabolism to occur efficiently.
Which surface of the elbow is in contact with the IR when taking an AP projection of the elbow?
The posterior surface of the elbow is in contact with the IR when taking an AP projection of the elbow. When doing an AP projection of the forearm, the elbow should be extended and parallel to the IR.
