Answer:
False
Explanation:
Eukaryotes along with some prokaryotes also perform the process of photosynthesis. Photosynthesis needs chloroplast and it is also found in some of the prokaryotes.
Sinkholes one major environmental risk of underground mining because, Underground mines may collapse after mining is complete, which causes sinkholes.
<u>Explanation:</u>
The movement that occurs on the surface of the ground is known as mine subsidence. This is mainly caused due to the collapse that happens in the cola or any clay mining works that occurs in the underground surface. When anything is extracted form the underground surface, some holes are made in the underground surface which are sinkholes.
The damages that are caused as a result of this can be claimed by Mine Subsidence Insurance Policy. This type of underground mining is very dangerous as it give rise to the formation of sinkholes. This is forms when there is collapsing of the surfaces in the underground occurs after the completion of the mining work.
Answer:
<em>When a queen gets old or weak and slows her production of queen substance, she is generally replaced by a new queen. New queens are also produced in colonies about to swarm. Virgin queen bees take what is known as a "nuptial flight" sometime within the first week or two after emerging from the pupal chamber.</em>
True: because it acts as a semi permeable membrane.
The question is incomplete as it does not have the options which are:
- Yes, because people's eyes move during sleep, and this stimulates the rods and cones.
- No, because rods and cones only convert light energy into electrical signals.
- No, because rods and cones never produce electrical signals.
- Yes, because the rods and cones are reproducing images that are then sent to the brain.
Answer:
No, because rods and cones only convert light energy into electrical signals.
Explanation:
The rod and cone cells are the photoreceptor cells present on the retina of the eye which receives the physical stimulus in the form of light and then converts the light energy into the electrical energy which is sent to the brain.
When we dream, our remains closed and no light is able to enter the eye as a result of which the rods and cones do not send the signals to the brain.
Thus, the selected options are correct.
