Answer:
Empty calories may be grasshoppers' downfall.
Explanation:
Many insect populations are declining, and a provocative new hypothesis suggests one problem is that rising levels of atmospheric carbon dioxide (CO2) are making plants less nutritious. That could spell trouble not just for insects, but for plant eaters of all sizes.
A positive charge is created in the cell that travels down it does a nerve
impulse begin in a neuron. Thus, the correct option is A.
<h3>
How the neuron get stimulus?</h3>
When a neuron receives a chemical stimulation, a nerve impulse is formed. The electrical action potential of the nerve impulse passes along the axon membrane to the axon terminal. Neurotransmitters are released at the axon terminal, which transfer the nerve impulse to the next cell.
The resting potential of a neuron is the electrical differential across its membrane. The sodium-potassium pump, a transport protein, creates the resting potential. This protein generates a positive charge by moving a high number of sodium ions (Na+) outside the cell.

Hey there!
Here is your answer:
<u>The proper answer to this question is option A "spiral".</u>
Reason:
<u>A spiral galaxy has a little rotation, but not enough to flatten out. </u><span><u>Spiral galaxies consist of a flat, rotating disc containing stars, gas and dust. These galaxies contain what any other galaxy would have for example: Stars, planets, moons, etc... </u>
Therefore the answer is option A.

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:
True.
