Answer:
Essay on types of digestion
Explanation:
Digestion refers to the breakdown of large food molecules into small food molecules so that can be absorbed by the blood. There are two types of digestion i. e. mechanical digestion and chemical digestion. in mechanical digestion, the food is broken down into smaller parts physically with the help of teeth while on the other hand, in chemical digestion, food is broken down into small particles with the help of chemicals such as acids and enzymes. This chemical digestion is carried out in the stomach where different types of chemicals are present.

A) Blood pressure decreases greatly; blood flow to the heart is inadequate, and blood pressure decreases.
Explanation;
-With negative feedback, the output reduces the original effect of the stimulus. While in a positive feedback system, the output enhances the original stimulus.
-Negative feedback is the most commonly used feedback loop in the body. Negative feedback is used to negate or counteract a stimulus without completely eradicating it.
-One key difference between the two feedback is that positive feedback loops are used to eradicate a stimulus. Another key difference is that responses through positive feedback become more amplified over time. So once a stimulus activates a positive feedback loop it is not turned off until the stimulus is completely removed.
Answer:
Average annual temperature in US cities would range between 50-70 degrees Fahrenheit
Explanation:
There are several factors that can influence the temperature of city in general. Higher altitude has a lower temperature because it has less air density and absorbs less sunlight. The city latitude coordinate also determines how much sunlight they will get. The closer the city to the equator, the more sunlight they can get.
Distance to the sea will influence the rate of rainfall and also influence temperature. Ocean currents can move hot water from other regions too.
