How does wind affect the amount of rain?

Answers

Answer:

please give me brainlist and follow

Explanation:

The rainfall loss rate increases as the wind speed increases and/or the rainfall intensity decreases.

Air Currents

Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.

If the blockage is removed from the blood vessel, what will happen to blood flow after removal?

Answers

Answer:

the blood would stop pumping, because the blockage allows the blood to move one way, but when there is not blockage, the blood would enter from both ways making it impossible to regulate

⦁ What is the purpose of the tiny hairs called cilia in your nose?
⦁ What are the purposes of the pharynx?
⦁ What is the purpose of the epiglottis?
⦁ How is the respiratory system linked to the cardiovascular system

Answers

Answer:

1. The respiratory system allows us to breathe . They bring oxygen into our body and remove carbon dioxide from the body .

2. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.

3. The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).

4. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.

5. The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to be transmitted to the whole body

(2 pts) Describe the process in which an ecosystem moves from a pioneer species to a climax community.

Answers

Answer:

As an ecological community develops, it goes through a series of stages called ecological succession. The enduring community, in which specific and environmental changes are minimized, is called the climax community.

Explanation:

Succession is a process that generally begins after a significant alteration or extinction of an existing community. During succession, a community begins from a point where pioneer species colonize a new area. Pioneer species actively work to provide nutrients to soils and thus allow life to begin to form in them.During this time, there is widespread growth of these fast-growing species. If this new development is in an area that has never been settled before, this is called primary succession. If colonization occurs where an area has been so severely disturbed that the original community no longer exists, this is called secondary succession. Primary succession begins with the establishment of pioneer species such as lichens and mosses. These change the physico-chemical characteristics of the substrate. Later, small plants such as grasses, shrubs and then trees arrive, until culminating in a climax community dominated by certain species. The equilibrium that characterizes the climax community can be altered by climatic, ecological and evolutionary factors.
