Answer:
s the cube size increases, the surface-area-to-volume ratio decreases (click to enlarge the table below). The vinegar can only enter the cube through its surface, so as that ratio decreases, the time it takes for diffusion to occur throughout the whole volume increases significantly.
There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy. Passive transport is explained in this section and Active transport is explained in the next section, Active Transport and Homeostasis.
Explanation:
<span>This is an example of convergent evolution. These animals gained these similar antler structures to be able to survive in similar environments. Convergent evolution gives organisms who are unrelated similar characteristics as they evolve. The characteristics are influenced by the organism's similar habitats and are given to them to make sure the organisms are able to adapt to survive.</span>
Answer:
as explained below:
Explanation:
it results as follow:
while you are jogging or doing any physical activity than your body requires alot of energy and produce a lot of carbon dioxide which causes the heart to beat fast as to remove co2 and take o2 from the blood leading to higher rate of pulse.
on the secon hand if you are sedentary , consumption and production of o2 and co2 respectively will decrease leading to the slow beating of heart leading to low pulse
The anesthetic that should be used is Propofol. Propofol would be the ideal choice for this
long operation, the patient would be put to sleep and feel no pain so the
surgeon can proceed with the operation and Propofol is used to help you relax
before and during general anesthesia for surgery or other medical procedure and
critically ill patients who require a breathing tube connected to a ventilator.
Answer:
A cell is defined as the structural and functional unit of an organism.
The average size of the prokaryotic cell lies between 0.1 to 10 micrometers whereas the average size of the eukaryotic cell is approximately 25 micrometers.
Four things are found in all the cells: genetic material (either DNA or RNA), cell membrane, cytoplasm, and the ribosome.
All the living cells grow and reproduce (sexually or asexually) and have the ability to respond to stimuli.
Thus, characteristics of a cell may include: cell grows and reproduces, responds to stimuli, contains DNA or RNA, not both , and contains a cell membrane.
