Answer:
There is an increase in demand for higher quality and quantity of food and other products.
Explanation:
There is an increase in demand for higher quality and quantity of food and other products. So, there is a huge requirement for technological innovation. Investment is needed in research and development to develop crops that are pesticide-free, resistant to disease, and able to face various weather conditions. Vertical farming and carbon-capture technology can be used to meet growing world food demands.
Answer:
The correct answer is - through facilitated diffusion and active transport.
Explanation:
Glucose is a six-carbon sugar molecule that is directly utilized by cells to provide energy. A glucose molecule is large enough to go through a cell membrane with simple diffusion.
Cells help glucose molecules to cross the cell membrane through facilitated diffusion and active transport. Active transport is of two types primary and secondary active transport to help the glucose molecule to cross the membrane.
Thus, the correct answer is - through facilitated diffusion and active transport.
Answer:
Yes, the biotechnology are associated with the genetic engineering as, the genetic engineering are the direct modification or manipulation of the organism which are using the biotechnology.
Basically, it the set of technologies which are used to modify the genetic cells including the transferring of the genes across the boundary to produced the organism. And with the help of biotechnology, new DNA are obtain by copy the genetic material by using the methods of DNA.
Answer:
Explanation:
The cell membrane separates the cell from the outer environment. The extracellular fluid contains the sodium ions (Na+), chloride ions (Cl-), while intracellular fluid contains potassium (K +) and negative anions.
The potential difference arises when the membrane is selectively permeable to some ions. The resting potential is -70mV.
When the neurons get excited, the sodium ions start to enter by sodium channels.
Now there are more positive ions inside the cell membrane. It disturbs the resting potential i.e. -70mV. This stage is known as depolarization.
When the inside environment of the cell is more positively charged, the potassium ions start to move out of the cell. It goes out by the voltage-gated channels. Thus resting stage is maintained and it is known as repolarization.
But the initial stability of the cell membrane has to be maintained. To restore the resting stage, the sodium ions start to move out of the membrane and potassium ions enter into the cells again. This is an active transport and has done by the Na+ - K+ pump. Here 3 sodium ions move out and 2 potassium ions pumped into the cell through the plasma membrane.
Thus the resting potential regains. The potassium ions come back into the cells against the concentration gradient and ATP provides the energy for this phenomena.
i dont understand what you are saying but water gets evaporated from the oceans due to the suns warmth all the water vapors condense, once the clouds get too heavy and there are too many water vapors in the cloud for it to handle, it percipitates (rains)
