More than 150 years ago, inventors began working on a bright idea that would have a dramatic impact on how we use energy in our homes and offices. This invention changed the way we design buildings, increased the length of the average workday and jumpstarted new businesses. It also led to new energy breakthroughs -- from power plants and electric transmission lines to home appliances and electric motors.
Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today.
The correct option is A: have a faster rate of osmosis
A cell containing many aquaporins will have a faster rate of osmosis.
Aquaporins are micro water channels within the membrane that allow for the exchange of water and other neutral molecules over the biological membranes of other organisms.
Due to the presence of Aquaporins in plants, they have a high diversity of regulation properties, localizations, and transport selectivity.
The rate of osmosis increases as the aquaporins facilitate the transfer of water at a faster rate.

Answer:
The correct option is option b that is<em> Homo erectus</em> is the common ancestor of<em> Homo neanderthalensis</em> and<em> Homo sapiens.</em>

They became extinct as they did't fight against environmental hazards and the major cause of their extinction that scientists have claimed that they did't adapt the modern techniques that the modern human does.
Process, transmit, and receive nerve impulses (electrical signals) from periphery to central nervous system.
Answer:
The answer would be D. 3,360
Explanation:
The solution is found by multiplying 16 times 15 times 14. The club has 16 members and after one role (president) is filled, there are 15 left to fill the next (vice). The same goes for the next role (treasurer). So 16 is multiplied with 15, then 14. This is more of a math question that biology btw.
