Answer:
Sympathetic nervous system
Explanation:
The sympathetic nervous system of the autonomic division prepares the body for stress or emergency conditions by generating the “fight-or-flight” responses. The sympathetic nervous system triggers the release of stress hormones from the adrenal medulla to generate the set of physiological responses.
There is dilation of the pupil, and an increased rate of heartbeat and increased blood pressure. Other responses include dilation of airways and dilation of blood vessels that supply blood to skeletal muscles, heart muscles, liver, etc. Under the given emergency condition, the sympathetic nervous system of Meghan was activated to generate the fight or flight response.
Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth's surface.
For the answer to the question above, there is no such thing as a non-living organism. Because organisms are only a term for living things.
1. Cellular structure: all living organisms generally have a cellular structure i.e., they are made up of one or more cells.
<span>The protoplasm is the physical basis of life. </span>
<span>There is no such fundamental and structural unit called cell in non-living things. </span>
<span>2. metabolism : The various life processes taking place within the body of an organism is collectively termed metabolism. The metabolic processes can occur only in living organisms and not in nonliving things. </span>
<span>3. growth, repair and death : Growth consists of the living organism absorbing materials entirely different from those that make up its body and convert them into body building substances. Growth in non-living substances such as crystal is at the cost of material similar to that of which it consists. Same substance is added without conversion. </span>
<span>The growth is permanent, irreversible process in living organisms but can be reversed in non-living things. </span>
<span>Growth is different in different parts of the body of an organism. Growth is uniform throughout in the non-living things. </span>
<span>Respiration, nutrition,excretion, movement,irritability, reproduction, life span, death, evolvability are other properties of a living organism.</span>
Answer: I would say the answer is D. ( my opinion )
Answer:
The correct options are:
- <em>The population of birds with large beaks will increase on the island.</em>
- <em>The trait for large beaks will be passed on to future generations through natural selection.</em>
Explanation:
According to the theory of natural selection, those organisms tend to survive in an environment which are better adapted to live in an environment and which can better adapt to changes that occur in an environment.
The drought caused the small, soft seeds to decrease more in number as compared to the large, hard seeds. As a result, the birds having large beaks were better adapted to live in the environment as compared to the birds having small beaks. So the population of the large beak birds increased and they passed their characteristics to the future generations.
