Answer:
0 just count all the atoms
by their color
Explanation:
Answer: Epithelium tissue refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. Connective tissue binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart. Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body
Explanation:
Answer:
Option C, making ATP to power cell activities
Explanation:
In cellular respiration, the energy stored in food is converted to readily available energy form i.e ATP (Adenosine Triphosphate) molecule. During cell respiration, the cell breakdown the glucose (carbohydrate) molecule into carbon dioxide (CO2), H2Oand ATP (energy molecule).
ATP being an energy molecule act as a source of energy for all metabolic processes. Along with ATP , higher level energy molecules like NADH is also produced.
Hence, option C is correct
Answer;
-Central conic vision
Explanation;
-Central vision is when our eyes focus straight ahead, allowing us to drive, read, and see details sharply.
-Central vision only covers about three degrees of our visual field, but it allows us to make very important judgments like estimating distance and understanding details in the path ahead.
Our sharpest, clearest vision is called central conic and is only about 3 to 5 degrees. This is our most focused vision where we can identify details and color
Surface area is an important factor in limiting cell growth because
a. the cell can burst if the membrane becomes too large.
b. materials cannot enter the cell if the surface is too large.
c. the cell may become too large to take in enough food and to remove enough wastes.
d. waste products cannot leave the cell if the cell is too small.
Answer:
c. the cell may become too large to take in enough food and to remove enough wastes.
Explanation:
The exchange of substances with surroundings is done by cells by the process of diffusion. The rate of diffusion of substances requires the presence of a higher surface area than volume. As the cells become larger, their surface area is reduced with respect to the volume. Therefore, larger cells can not support the diffusion of substances in and out as required for its proper functioning. If cells are allowed to grow continuously, they will not be able to intake the requires materials such as food and to release the waste outside.
