Look up intelligent design. Intelligent design is an acceptance and understanding of both creation and evolution going together.
Answer:
Yes
Explanation:
This can be explained with the concept of induced resistance. it is the ability of a plant to respond the certain chemical released from the damaged body parts,The diffusion of the chemical stimulates all other plants parts and other plants to be less tasty and therefore not pleasant to eat. Thus the more the extent of damage to the plant,the higher the volume of chemicals released and therefore the less tasty the plants and lower the damages-negative feedback mechanisms. Since this restored the plants to relatively constant internal environments,this is homeostasis.
Hornworm caterpillar damages tomatoes plants leaves,leaving holes.When a tomato plant is eaten,it releases chemical substance called methyl jasmonate. The latter would be received by adjacent plants parts or other tomato plants. The receptive tomatoes plants therefore becomes less tasty. Hence the caterpillar after destroying the initial part of the tomato plants would not be able to continue with the feeding and therefore feed on one another leading to their death,turning them to cannibal caterpillars.
Since in an attempt to maintain the relatively constant internal environment plant releases methyl jasmonate to prevent futher damage and therefore ensures stability of the plant.
Answer:
B) astrocytes
Explanation:
Cells other than neurons that play an important role in the normal functioning of nervous system are called Neuroglia or glial cells.
Satellite cells, astrocytes, schwann cells and oligodendrocytes are all examples of glial cells.
⇒Satellite cells provide protection and nutrition to cells in peripheral nervous system ( peripheral nerves and ganglia).
⇒<em><u>Astrocytes</u></em> play an important role in central nervous system (brain and spinal cord). They provide protection to neurons, scavenge ions, form the blood-brain barrier and also maintain extracellular environment suitable for neuronal functioning.
⇒Schwann cells are found in the peripheral nervous system and myelinate the axons of neurons.
⇒Oligodendrocytes are found in central nervous system and produce myelin sheath which myelinates (insulates) axons of neurons. Their function is similar to schwann cells but in the central nervous system.
From the above discussion it is clear that the answer is B) Astrocytes as these maintain a suitable chemical environment for the neurons.
