lungs and capillaries both have porous linings that allow certain substances to move into or out of the structures. Which function do these porous linings most likely serve in living organisms?
A. heat release
B. gas exchange
C. carbohydrate absorption
D. osmotic pressure regulation
Answer:
B. Gas exchange
Explanation:
because the lungs bring air into your body, it needs a way to transfer the oxygen into your blood stream.
Luckily for us, our lungs have porous linings, which will help the oxygen go directly into our blood stream.
The porous structure of the blood capillaries and lung tissue allow the them to exchange gas
The porous structure of the lungs allow to exchange gas from the gas in the blood. Blood capillaries are tiny blood vessels in the body.
The gas in the blood was collected from the tissue from the body parts which is made possible because of the porous lining of the blood capillaries.
Therefore, the porous structure of the blood capillaries and lung tissue allow the them to exchange gas.

In what year should we expect ocean pH to adversely affect zooplankton population?
The year we should expect ocean pH to adversely affect zooplankton population is 2030.
What are zooplanktons?Zooplankton is a small floating or weakly swimming organisms that drift with water currents and, with phytoplankton, make up the planktonic food supply upon which almost all oceanic organisms are ultimately dependent.
Ocean acidification may affect zooplankton directly by decreasing in pH, as well as indirectly by trophic pathways, where changes in carbon availability or pH effects on primary producers may cascade up the food web thereby altering ecosystem functioning and community composition.

Explain how nitrate ions help plants to grow.
Answer:
Explanation:
Both nitrate ions and ammonium ions can be taken up by plants (some prefer one to the other). These ions provide nitrogen for the plant to make its own amino acids for protein synthesis. Except in very high nitrogen soils, the addition of extra nitrate will stimulate plant growth.
Nitrogen is an essential macronutrient that is a component of many essential molecules, such as amino acids, proteins, nucleic acids, and chlorophyll.
What are the roles of nitrate in the growth of plants?Nitrate ions are essential nutrients for plant growth and development. Nitrogen is the fourth most abundant element in plants and is crucial for the growth of leaves, stems, and roots.
Plants require nitrogen in the form of nitrate because it is the most oxidized. It is an easily available form of nitrogen for plants to take up from the soil. Nitrate is absorbed by plants through their roots and transported to the plant cells, where it is used to synthesize amino acids, proteins, and other essential molecules.
Nitrate plays a crucial role in the process of photosynthesis, which is the process by which plants convert sunlight into energy.

Answer:
Protect coastlines from storms, erosion and provide habitat.
Explanation:
Coral reefs protect coastlines from storms and erosion as well as provide a habitat for thousands of aquatic animals. These points rashid must include in his seminar. Coral reefs are very important for the marine ecosystem because it can save the soil from erosion and decreases the intensity of storms by acting just like barrier. It provides food as well as living place for many organisms so these point are very important to be included in the seminar.

which structure in the figure would most likely be used to form muscles and connective tissue
Q3 because the muscle tissue isnt that complex and it inst that connective.Explanation:
Bone and muscles are the connective tissue. Muscle tissue is made up of sheets and fibers of muscle cells woven together.
What is connective tissue?Animals have a specific tissue called muscle that contracts when activated, applying forces to various body parts. Together, these fibers and sheets are referred to as muscles, which regulate many other contractile processes as well as an organism's movements.
Depending on their purpose, animals have one of three types of muscle. Despite modest differences, these muscles have a similar structure and function. Muscle tissue has a unified function and is frequently joined by the same nerve bundles.
Therefore, Bone and muscles are the connective tissue. Muscle tissue is made up of sheets and fibers of muscle cells woven together.

HELP! A 20-kg bag of rice dropped from an airplane. What is the gravitational force on the bag? Acceleration due to gravity is 9.8 m/s/s.)
10.02 N
19.6 N
20.8 N
196 N
Answer:
20.8
Explanation:
I took it and it was right
196N is the gravitational force on the bag. So, the correct option is D.
What is gravitational force?Any two items in the universe can be attracted to one another by the gravitational force. All mass-containing objects are drawn towards one another by this attraction, which also keeps the moon in its orbit around the Earth and the planets in their orbits around the sun.
The mass of the two objects and their separation determine the gravitational force's strength. The force of gravity between two objects is directly proportional to their masses and inversely correlated to the square of their distance, according to Newton's law of universal gravitation.
The gravitational force on the bag can be calculated using the formula:
force = mass x acceleration due to gravity
Plugging in the given values, we get:
Force = 20 kg x 9.8 m/s/s
Force = 196 N
Therefore, the correct option is D.
