Answer:
Rabbit's population will reduce drastically
Explanation:
As it is clear from the given description, that drought adversely affects the production of flower and berries and hence the population of rabbits depending on berries and flowers will be adversely affected. Therefore, there are high chances of rabbits dying because of insufficient food during drought
Also, the foxes and hawks feed on the babies of rabbit. This further reduces the population of rabbits as the new ones are killed before attaining fertility.
Overall due to both predation (by foxes and hawks) and the drought the population will reduce drastically.
Answer:
Abiotic factors affecting life in the polar regions include temperature, sunlight and precipitation.
Answer:
<em>condensation or dehydration synthesis</em>
Explanation:
A condensation reaction can be described as a reaction in which two molecules combine to form a larger molecule. A water molecule is usually dispersed during this reaction.
For example, two amino acids join to form a protein. The bond formed between them is known as dipeptide bond.
Dehydration synthesis is also a reaction in which molecules via covalent bonds to form larger molecules. As water molecule is released during this process, this reaction is termed as dehydration synthesis.
Answer:
B. Curare will only affect muscles with ACh receptors, paralyzing them.
Explanation:
Acetylcholine receptors are located on the surface of muscle cells, especially in the synapse between muscle cells and nerve cells. Muscles are constantly pumping sodium out of their cells, so, when they are relaxed, there is more sodium outside than inside. When they get the signal from the nerve, the channels open and sodium ions get back inside, starting the process muscle contraction. IF curare binds to the site where Acetylcholine is supposed to act, and thus blocking all this muscle contraction signal, it will produce a progressive paralysis of all muscles.
