Explain why respiratory surfaces must be moist
Answers
Answer:
In animals, the process of respiration is aerobic respiration, exchange of gases takes place ( carbon dioxide leaving the cell, oxygen entering)
Single cellular organisms can exchange gases directly across their cell membrane through the process o diffusion.
Large animals cannot maintain gas exchange by diffusion across their outer surface. A respiratory surface is covered with thin, moist epithelial cells that allow oxygen and carbon dioxide to exchange. Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.
Explanation:
Answer:
so that carbon dioxide and oxygen can exchange
Explanation:
Those gases can only cross cell membranes when they are dissolved in water or aqueous solution.
The diagram shows some of the structures in a human lung. Where is the carbon dioxide concentration highest? Support your answer with the scientific details required.
Answers
Answer:
W - Facilitates movement of air by expansion and contraction, X - Traps dust and helps to filter inhaled air, Y - Prevents the wind pipe from collapsing, Z - Help in exchange of gases.
Explanation:
Diaphragm is the muscle that separates the thoracic cavity from the abdomen. The diaphragm is the main muscle of respiration. Contraction of the diaphragm muscle expands the lungs during inspiration when breathing air in. The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs. Hairs and mucus lining the nasal cavity help to trap dust, mold, pollen and other environmental contaminants before they can reach the inner portions of the body. The trachea, or windpipe, is a 5-inch long tube made of C-shaped hyaline cartilage rings lined with pseudostratified ciliated columnar epithelium. The trachea connects the larynx to the bronchi and allows air to pass through the neck and into the thorax. The rings of cartilage making up the trachea allow it to remain open to air at all times. Gas exchange of oxygen and carbon dioxide takes place in the alveoli. Oxygen from the inhaled air diffuses through the walls of the alveoli and adjacent capillaries into the red blood cells. The oxygen is then carried by the blood to the body tissues.
The part of the lungs where Carbon Dioxide concentration is highest is in the part labeled A.
The entire diagram is called ALVEOLI.
This structure is a semi-permeable membrane wired with blood vessels on its walls. It is in these sacs that the body gives off carbon dioxide and takes in oxygen. The blood vessels which are wired around the sacs are called Capillaries.
The part labeled B is the pulmonary artery. It feeds de-oxygenated blood to the capillaries. Through the walls of the capillaries, the carbon dioxide is removed from the blood into the alveoli and takes up oxygen from the air in the alveoli. The oxygenated blood then moves back into the body via the pulmonary vein which is labeled D on the diagram.

11. How would sheep be kept and fed in an extensive grazing system?
O A. Sheep would be kept on feedlots to reduce the amount of space they take up.
O B. Sheep would be allowed to graze on rangelands without rotational stocking.
O C. Sheep would be allowed to graze on a pasture during specific times of the year.
O D. Sheep would be rotated through paddocks to allow land to rest between grazings.
Answers
Answer:
Option B
Explanation:
In an extensive farming, animals are raised in the most natural way and hence the animals are allowed to roam around the farmlands without any barrier and they are free to express and control their behavior.
Sheep in extensive farming are allowed to graze freely across the farmland at any time of the day.
Hence, option B is correct.

A man who is color blind married a woman with normal color vision whose father was colorblind, what is the probability of a child with colorblindness?
Answers
Answer:
However, in this case, it would seem that due to the genetic inheritance of the mother the chances of their child being color blind would be approximately 50% because each parent is a carrier. However, the chances of inheriting a colorblind X chromosome would be twice as likely for a female child.

True or False: Growing crops raises the carbon levels and causes global warming.
Answers
Answer:
For rainfed wheat grown in more arid climates, such as southern Africa and India, results show that doubled carbon dioxide levels, and their associated climate change impacts, increase yield by 8 percent, an increase that's driven by improved crop water productivity of up to 50 percent. true
Explanation: do you want one?
Growing crops does not raise the carbon levels and does not cause global warming ; ( i.e. the statement in the question is False ).
Crops/plant make use of carbon dioxide in the atmosphere during photosynthesis, releasing oxygen and energy into the atmosphere as a by product from photosynthesis.
Global warming is caused by the presence of green house gases in the atmosphere and the removal of CO₂ by plants from the atmosphere during photosynthesis helps with reduction of a green house gas ( CO₂ ).
Hence we can conclude that Growing crops does not raise the carbon levels and does not cause global warming .

log?
Answers
Answer:It is a parasitic relationship
Explanation:This is because the mushroom feeds of the Log and the log doesnt get anything in return
Answer:
(4)
Explanation:
Mushrooms grow on logs for their nutrients. Remember mushrooms are decomposers that is why they would use the log for nutrients. The tree is already dead and is rotting so it can’t produce oxygen and the log isn’t benefiting from the mushrooms since it’s dead
this is why the correct answer is (4) The mushrooms use the log as a food source.

B) A worm that lives inside a bear.
C) A bear that kills and eats fish.
D) A bear that has worms in its gut.
Answers
Answer:
B) A worm that lives inside a bear.
Explanation:
A parasite is a living organism that lives inside or outside of another organism called a HOST in order to obtain nourishment from such organism. A parasite that lives inside its host is called ENDOPARASITE while a parasite that lives outside its host is called ECTOPARASITE.
In this question, a worm that lives inside a bear is a PARASITE because it is living inside the bear, which is the host in order to obtain nourishments. Note that, the answer is not option D because the bear is a HOST not a parasite.
