Cyanobacteria, also known as blue-green algae, are found in vast quantities in fresh and salt water. Cyanobacteria are able to conduct photosynthesis. By utilising energy from the sun, they produce carbohydrates from water and carbon dioxide. As a byproduct, they produce oxygen. So cyanobacteria provided oxygen to the atmosphere that allowed other lifeforms to develop.
Answer:
Transport vesicles, containing partially processed proteins, fuse with the folds of the <u>Golgi apparatus (cisternae)</u> on the cis face and bud from the cisternae on the more distal side (trans face).
Explanation:
Some of the matrix proteins form long, filamentous tethers that are thought to help retain Golgi transport vesicles close to the organelle. When the cell prepares to divide, mitotic protein kinases phosphorylate the Golgi matrix proteins, causing the Golgi apparatus to fragment and disperse throughout the cytosol.
Answer:
The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
Speciation is the evolution of one species into two different kinds, and when they become isolated, that is the final step, since they cannot interbreed any longer.
Answer:
B. Energy can be thrown away.
Explanation:
Answer:
<em>The correct option is D) The energy of the car will decrease, and the energy of the block will increase. </em>
Explanation:
As we know energy cannot be created or destroyed but it can change from one form to another. When the wooden car will collide with the wooden block, some of the kinetic energy with which the car was moving will be passed to the wooden block. As a result, the wooden block will also get pushed along the track. Meanwhile, as the wooden car had transferred some of its energy, its energy level will decrease and it will move slower than before pushing the wooden block along with it.
