Answer: Provides support for the blade of the leaves.
Explanation:
Vascular tissues are conducting tissues formed from specialized cells . The two conducting vascular tissues in plants are xylem and phloem.
Xylem tissue transport water and nutrients from plant roots to all part of the plants. Phloem transport sugars. It also provide structural support for plants. Vascular tissues run through the veins of the leaves and provide support. Vascular tissues are found in vascular plants.
Answer:
Neuron would be unable to receive signal from environment and previous neuron.
Explanation:
A neuron cell comprises of dendrites, cell body and axon. Dendrites are the projections of neuron cells that receive the electrochemical signal from other neurons and transfer them to soma (body) of a neuron cell. While axon transfer it to next neuron from cell body.
So if the mutation cause loss of dendrites of neuron cells it would be unable to receive the signal from the previous neuron and environment because receptors to receive signals are present on dendrites. Consequently the cell would loss the communication with other cell and that cell may dies and it can also cause paralysis of that particular area because of loss of communication.
There seems to be a typograhical error in option B and C: the word 'community' was repeated twice. However, I've corrected it
Answer: Option B) A community refers to all the populations in an area; a ecosystem includes both biotic and abiotic components
Explanation:
The important difference between community and ecosystem is that the effect of abiotic i.e non- living factors, are considered in an ecosystem, unlike in a community.
Thus, an ecosystem refers to a community of biotic factors i.e plants, animals and microorganisms, interacting together with their non-living environment.
Community, on the other hand, refers to interdependence that occur within a group of plants and animals that occupy a given area. Thus, community considers only biotic factors.
