Answer:
Gas makes things buoyant by making the volume of an object lighter than the surrounding fluid it is trying to displace.
Gas Buoyancy is useful in the following ways;
• Airships
• Steel ships and
• All floating and flying vessels
Explanation:
Buoyancy is the tendency of an object to float in a fluid such as air or water. It is a phenomenon that was theorized by the mathematician, Archimedes known as the Archimedes Principle.
It states that the upward buoyant force that is exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces.
The principle explains the reason why objects float and fly.
So, when an object is immersed in a fluid, it can float due to the upward force exerted by the fluid on the object. But for this to happen, the object has to weigh less than the fluid it is displacing.
This is where the use of a gas comes into play.
Because the object may be heavier than the surrounding fluid it is trying to displace, it is filled with a large amount of gas (usually hydrogen and/or helium) which is lighter. This makes the volume of the gas and the object put together lighter than that of the surrounding air.
This is what causes objects to float or fly
Answer:
Research for species is done by microscopic view. The micro organism like fungi and bacteria are difficult to be observed by naked eye.
Explanation:
The research process includes the detailed view of the properties of micro organism. Their way of living separates them from each other. Parasites used to live in the body of their victim.
<h3>Adverse effects of covering the land with concrete and asphalt is Natural resources are depleted.</h3>
- Asphalt is a petroleum-based product. Concrete requires rock, sand and a fabricated cement component to strengthen the material hold the pavement material.
- Fortunately, industry innovation has led to meaningful progress toward resource conservation.
- Road construction companies have developed ways to reuse existing concrete and asphalt by remixing it materials.

Answer:
The correct answer is option d. "Its conformation will change when both an ion and a small molecule bind to it".
Explanation:
The secondary active transport is a form of active transport at which a ion (typically Na+ or H+) is transferred down its electrochemical gradient to the uphill movement of another molecule. Secondary active transport takes place by the conjunctive work of membrane-bound proteins and sodium–potassium pumps. During secondary active transport, both of these proteins change its conformation when an ion and a small molecule bind to it. This change in conformation makes possible that the ions and the small molecules pass through the membrane.
