A student wanted to look at germination of five different seeds in vermiculite (a soil additive). He planted the seeds in identi

cal containers and left them together in full sunlight. He gave each seed the same amount of water and charted the germination of each seed type. What is the independent variable in this experiment? (a) vermiculite (b) germination rate (c) seed type (d) light (e) amounts of water

Answer: (c) seed type

Explanation:

An independent variable is the one which can be altered or manually manipulated in an experiment. The effect of such manipulation can be examined on the dependent variable of the experiment. The dependent variable cannot be manipulated in an experiment instead it is the outcome of the experiment.

The seed type is the correct answer because the seed type can vary and the effect of which can be examined on the seed germination process and rate of seed germination.

Since fish feeds primarily on large amphipod, therefore what we expect to remain to evolve on ponds containing fish would be smaller amphipod or crustacean. Then correct answer to this question would be:

Can fatigue seriously impair driving ability.<br> a.no<br> b.yes
NikAS [45]
The correct answer is B.

When your body and mind are fatigued you are out into a field of fuzziness. When dealing with extreme fatigue, there is the obvious problem of falling asleep in the road, which could result in terrible and most likely fatal accidents. But there are also other problems mentally and visually that can occur that would impair your driving ability when facing extreme fatigue.

I hope this helps! :)

identify the subcellular structure of the neuron that forms the basis for the transmission of nerve impulses. (2 points) describ
melisa1 [442]

The subcellular structures of neuron that forms the basis for transmission of nerve impulses are the synaptic vesicles.

What are the steps in impulse transmission between neurons?

  • The action potential or nerve impulse reaches the <u>axon</u> of neuron and depolarises the membrane.
  • Voltage gated Calcium channels open .
  • Arrival of action potential causes the synaptic vesicle to attach to presynaptic membrane.
  • Calcium influx triggers release of neurotransmitter.
  • This neurotransmitters bind to postsynaptic membrane and new impulses are created.

Synaptic vesicle under resting condition:

  1. The neurotransmitter molecules are stored in synaptic vesicles.
  2. If the neurotransmitter leak from the vesicles, they are destroyed by enzymes.
  3. During resting condition, they are placed randomly.
  4. When an impulse reaches the axon, vesicles are arranged in the presynaptic membrane.

Thus from the above we can conclude that, synaptic vesicles are the subcellular structures in transmission of nerve impulses and , under resting condition they are placed randomly.
