Explain why is it important to investigate water retention properties of soils
Answer:
Soil water can affect the structural integrity or coherence of a soil; saturated soils can become unstable and result in structural failure and mass movement. Soil water, its changes over time and management are of interest to geo-technicians and soil conservationists with an interest in maintaining soil stability.

The movement of water across cellular membranes through aquaporins is known as?(1 point)
endocytosis
active transport
simple diffusion
osmosis
Answer:
- osmosis -
Explanation:
The quick trick is that osmosis can only occur in water or insolvent movements!
Think of fish, fish have a lot to do with osmosis because the water will go through the fish's skin/gills which will help them breathe and thrive.
!! hope that helps love you guys !!
The movement of water across cellular membranes through aquaporins is known as osmosis. Water moves down the concentration gradient. The fourth option is the correct answer.
How do molecules move across the cell membrane?Molecules can pass the cell membrane both actively and passively. In passive transport, no energy or ATP is required. Molecules can move from a higher concentration to a lower concentration.
Diffusion and osmosis are examples of passive transports. In diffusion, gases and other small molecules pass the cell membrane from a higher to a lower concentration. Water is a polar molecule, so it doesn't pass the membrane due to its nonpolar nature. Cells have aquaporin channels that are made for water.
Through aquaporins, water passes into the cell. This is called osmosis. In active transport, energy is required. When a molecule passes from a lower concentration to a higher concentration, energy is needed. An example is sodium-potassium ATPase.
Hence, the correct answer is osmosis. The fourth option is the correct answer.

Which of the following is NOT an accessory gland of the male reproductive system?
Answer:
a. Testosterone gland
Explanation:post protected
Testosterone gland is not an accessory gland of the male reproductive system.
What is Testosterone gland?Testosterone is a hormone that is primarily produced in the testicles in males and in small amounts in the ovaries and adrenal glands in females. It is a vital hormone that plays a critical role in the development of male reproductive tissues and secondary sexual characteristics, such as muscle mass, bone density, and body hair growth.
Testosterone is also essential for maintaining sex drive and overall physical health in both men and women. The production of testosterone is regulated by the hypothalamus and pituitary gland in the brain, which release signals to the testes to produce testosterone.
Certain medical conditions, lifestyle factors, and aging can affect testosterone production and levels, which can have significant impacts on health and wellbeing. Treatment options are available to address testosterone deficiencies and imbalances.

7. Explain the following: All compounds are substances,
but not all substances are compounds."
Answer:
Below
Explanation:
"All compounds are substances, but not all substances are compounds."
In simpler terms, let us use an example. Look at the image below.
In a big circle, there are substances. And in the small there are compounds. Since the compounds are inside the big circle, they are compounds, but as you can see, the substances are not inside the compounds so they cannot be considered compounds.
If you think about it, a substance is anything. So would you think a bottle, for instance, is a compound? A compound is a mixture of molecules. And a substance is most likely a combination of atoms, which are elements.
