Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
Life processes are important to carry out daily life activities. They help to produce energy and maintain homeostasis in the body. The life processes help a body survive with the changes in the environment.
Answer:
Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.
The mitochondria creates carbon dioxide (CO2) as a waste product of cellular respiration (the process that makes energy for your body). Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell. It too is small and uncharged so it can pass through cell membranes easily.
These movements require no energy (in the form of ATP) on behalf of the cell.
Explanation:
Your BMI (body mass index) is 21.6, which is a normal BMI. So, you are NOT overweight.
Answer:
C. channel protein - allow passage of material through the hydrophilic pore
Explanation:
Channel Protein is a transport protein that has an aqueous channel throughout its transmembrane molecule, which allows the free movement of certain ions or molecules through diffusion, allowing these materials to pass through the hydrophilic pore.
From this we can conclude that the correct answer to your question is the letter C.
Answer:
The answer is "TRUE!"
Explanation:
Weight is a source of forceful motion that is generated by the pull of gravity. Gravity that is originated in the center of the earth, attracts smaller objects towards that center, in which the measurement of how strong that force really is, is weight.
