Answer:
e. All of the above are correct.
Explanation:
Active transport is a type of transport in living systems in which molecules/ions/substances are moved or transported against their concentration gradient i.e. from a region where the substance is LOW to a region which it is HIGH, across a membrane. Since molecules are transported across a memembrane against their concentration gradient, an energy input in form of ATP is needed to do so.
Active transport is used in living systems to transport out secretory products and waste material against concentration gradients, take up nutrients from the environment against concentrations gradients etc. Since ions are substance moved by active transport from a low region to high region, there is an imbalance in the intracellular concentration of ions, such as Na, K etc.
Since there is no equilibrium in the concentration of ions on opposite sides of the membrane, an electric potential is formed across the membrane i.e. one part of the membrane will be more positively charged than the other.
Answer:
Explanation:
a, since binary means two number. For instance, computers run on binary programming code(1's and 0's).
Answer:
A
Explanation:
If the woman has only A and B, that means she has no recessive genes and that her blood type is IA and IB, and since the man has no A or B, it means that he only has recessive so he would have i and i. Hope this helps!
Ps. It looks like A and B are the same answer but, in B for the 5th box (Row 2, Column 2) the order of the lowercase i and the uppercase I are switched.
Hmm good question. Well I would have to test it for where there are no living life. I would have to build another NASA in the County because there is plenty of room there. Mars is made out of Dusty Crust that is about 30 miles thick. And let's say that the desert's Dusty Crust is about 5 miles - 15 miles thick. That will give about the same amount of surface that mars has. So we would know what to build for a perfect lander to work on Mars. This isn't much but it is something.
