Answer:

Scientific question:

Does light intensity effect the growth of a plant?

Hypothesis:

If the light intensity is increased, then the plants will grow more.

Experiments and observation:

Place a plant in dark, take three other plants and vary the amount of light intensity in them. For plant 1, the light could be given for 2 hours a day. For plant 2,the light could be given for 4 hours a day. For plant 3, the light could be given for 6 hours a day.

Results:

We see that the plant which received 6 hours of light grew more.

Conclusion:

The hypothesis is correct. The light intensity effects the growth of plants. Plants which receive more light grow more.

BRAINLIESTTTT ASAP!!!<br><br> How can space exploration impact the economy and culture of a region?
Lilit [14]
Hello, Geny5!! Space exploration has affected the economy by simple things such as technology and airline businesses. In the technology field, portable devices, like cell phones, mostly started with portable communication systems in space. Whereas the airline business, a lot of the technology in airplanes today was used in order to travel to space and for exploration. If you think about it, when astronauts talk to each other in space, they are using portable technology like cell phones. In airplanes, they have oxygen and the ability to control how to stay in the air/fly/land, like rockets and other things NASA uses. Culturally, it would boil down to technology, again. Many things in our lives today are centered around technology, just like space exploration. They have to have the technology to get them into space and come back down. If it wasn’t for space exploration, we wouldn’t have computers, cell phones, or even solar panels. I hope this helped!! Have a great evening!! :)

A preganglionic sympathetic nerve cell, with an axon terminal in the superior cervical ganglion, that releases acetylcholine ont
givi [52]

Answer:

neurotransmission

Explanation:

  • When the nerve impulses are transmitted from one neuron to another or from one neuron to a muscle, then such a type of signalling is known as neurotransmission.
  • When neurotransmission occurs between two nerves, then the neurons communicate by release a neurotransmitter into the synapse between the two neurons.
  • The neurotransmitters are released by the axon terminals from the presynaptic neuron and they bind onto the dendrites of the postsynaptic neurons.
  • Therefore, in the given example the release of acetylcholine (neurotransmitter) from the preganglionic nerve cell onto the postganglionic nerve cell is an example of neurotransmission.

Compare the reproductive capacity of a starfish with at least three other animals you know about.
Alja [10]

Answer: The reproductive capacity of the star fish is asexual.

Explanation: The starfish is known to reproduce another of its kind by fragmenting. It is by breaking a part of its one or more arms. The broken fragment grows to be individual starfish. And if you are wondering the broken arm of the parent starfish, well it regrows.  

You can observe this phenomenon in plants as well and definitely with other sea creatures and bacteria, e.g., corals, sponges, and cyanobacteria
