Answer:
<em>Cellular transport is the movement of ions or molecules across the membrane of the cell through either active or passive process.</em>
Explanation:
During active transport, ATP (Adenosine triphosphate) is used. In passive transport, ATP is not used. In active cellular transport, the ions move across the membrane against the concentration gradient.
For ATP to be used, it has to get hydrolyzed thereby forming ADP and inorganic phosphate. On the other hand, ADP captures the energy through the oxidation process taking place in the cell.
A) The answer is 0.1/year.
The reproductive rate for the population can be expressed as:
(number of births - number of deaths)/number of individuals = (55-5)/500 = 50/500 = 0.1
b) The answer is exponential growth.
The exponential type of population growth occurs
when resources are unlimited. <span>When there are no limiting factors, population
exhibits exponential growth. If every year population has mentioned reproductive rate, that means it is not limited by any factor (food, space, etc.). Thus, it must be exponential growth.</span>
Hello.
The difference between plant and animal vacuoles is that plants have one large vacuole enclosed by a membrane and animal cells have many, smaller vacuoles. The vacuole in a plant cell will often take up nearly 90 percent of the cell’s volume.
Only animal cells have lysosomes, only plant cells have chloroplasts,While plants cells have a rigid cell wall, animal cells have a thin and flexible plasma membrane,Plants cells have a large central vacuole and animal cells have many small vacuoles.
Have a nice day
Answer:
3,2,4,1 is the correct order.
Explanation:
3 would be cuz initially there were no life forms. 2 cuz bacteria came and then primitive and simple animals and plants evolved. Then 4 cuz simple life came from bacteria. Then 1 bc from those simple life an complexed life evolved.
Three roles of the DNA molecule in heritage are in storage, copying and transmitting genes.
A-DNA: It is a right-handed double helix similar to the B-DNA form. ...
B-DNA: This is the most common DNA conformation and is a right-handed helix. ...
Z-DNA: Z-DNA is a left-handed DNA where the double helix winds to the left in a zig-zag pattern.
