Answer:
Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.
Respiratory surfaces in both human beings and plants have several characteristics that are peculiar and similar to each other. There are some requirements to be met for gaseous exchange to occur.
Two characteristics that the respiratory surface used for gaseous exchange in human beings has in common with the respiratory surface used in flowering plants include ---
1. Respiratory surface must be thin and allow for rapid diffusion.
2. These surfaces must be in contact with air or fluid.
Respiratory surfaces in plant living cells in the stem are organized in thin layers close to the surface.Their loose packing ensures air spaces where they are in close contact with the airflow either in or out. In humans, the respiratory surface is thin allowing for rapid diffusion of oxygen in and CO₂ out. They are also always in contact with the bloodLearn more: https://brainly.com/question/9128660

How does Earth’s position relative to the Sun cause the four seasons?
a. Earth orbits the Sun once a year and is in a different position with respect to the Sun every three months, resulting in four seasons.
b. The tilt of Earth’s axis with respect to its orbit changes back and forth approximately 46 degrees every six months, resulting in four seasons.
c. Earth’s axis is tilted with respect to its orbit, so, as it revolves around the Sun its tilt with respect to the Sun changes, resulting in four seasons.
d. Earth rotates on its axis every twenty-four hours, and, since the axis is tilted with respect to the Sun, different parts of Earth experience different day-lengths, resulting in four seasons
Answer:
c. Earth’s axis is tilted with respect to its orbit, so, as it revolves around the Sun its tilt with respect to the Sun changes, resulting in four seasons.
Explanation:
Earth’s tilted cause the four seasons in different parts of earth. In summer, the surface of earth is present directly to the sun causes high temperature of that region while on the other hand, the same region experience cold temperature in winter due to tilt of the earth which does not allow the solar radiation comes directly to that region of the earth that leads to cold temperature.

What do you know - This pandemic started in Wuhan, China in December 2019
What do you wonder - If this pandemic will end in 2022 or in early 2022
What have you learned - The virus causes respiratory diseases.
Explanation: The coronavirus is a deadly virus that started in Wuhan, China in December 2019. At least 11.7M cases are reported, and 2.59M died. They're vaccines for it, but people 16+ can get the vaccine. People that didn't get the vaccine have a greater risk for catching it unless they're wearing a facemask. Facemasks can protect people from the virus because, the virus gets in you from your mouth, nose, and eyes. That's why people say to avoid touching your face.

Which of the following might restrict the growth of a population?
O Mild winters
O Increased predation
o Increased numbers of prey
O Ample rainfall
30 POINTS!!!!
Answer: Increased predation, and mild winters.
Explanation: As the prey population increases, there is more food for predators. So, as the number of predators increases, more prey are captured.
Mild winters would cause all of the plants to die, therefore prey would also die due to lack of food and cause predators to die as well for the same reason.
Side note: It might also be ample rainfall but I didn't know if they meant ample rainfall as in flooding or not, if it means flooding then that could be an answer, too. And I also wasn't sure if this was multiple choice or not.
Good luck! :)

How are humans circulatory system similar and different to other animals
Answer:
Humans have a heart with two atria and two ventricles that pushes blood in one direction. Some animals have hearts similar to humans but, other animals have only one atrium and one ventricle or a cardiovascular system that can push blood in two directions.
Humans circulatory system is similar due to presence of artrium and ventricles and different to other animals due to number of heart chambers.
How human circulatory system similar and different to other animals?Humans have a heart with two atria and two ventricles that prevents bactward flow of blood. Some animals have hearts similar to humans but, other animals have only one atrium and one ventricle that can push blood in two directions.
