Answer:

<h2>Air pollution.</h2><h2>Landscape degradation.</h2>

Explanation:

Mining the surface have specific consequences. Since that is at the surface, air is gonna contaminate rapidly because of all those factors that don't belong to that context. Also, the soil is gonna be damaged, because to do mining activities you have to dig, changing the structure and consistency of the surface.

What are the three examples to justify Newton first law of motion .

Sergeu [11.5K]

Explanation:

1.Law of Inertia

Inertia : is the ability to resist change in motion.

Example; if you roll a ball it will keep running unless you change it's direction with the help of friction..

2. second law of motion states that an object will accelerate when an unbalanced force is applied on a mass..

unbalanced force is a type of force where total force≠zero, means the object will move..

Example; if you will try to push a truck will be less but if you push a car the acceleration will be more.. because car has less mass..

3. the third law of motion state that foreign every action there is a opposite reaction..

Example; can you throw a ball on the floor ...the floor pushes back that the ball..

Match the following. 1. the basic building block of all forms of life resolving power 2. the idea of Schleiden and Schwann that

Roman55 [17]

Answer:

1. Cell

2. cell theory

3. Organismal theory

4. resolving power

Explanation:

The cell is the smallest known unit of all living organisms. They are called the building blocks of life. An organism can be unicellular (made up of one cell) or multi-cellular (made up of many cells).

2. Cell theory was formulated and developed by Schleiden, Schwann, and Virchow. They are considered as the basic principles of biology.

It states:

1. Living organisms are made up of cells.

2. Cells are the basic unit of life.

3. Cells are formed from pre-existing cells.

4. Energy flows inside the cell.

5. DNA is passed on from cell to cell.

6. All cells have the same basic chemical composition.

3. Organismal theory is the intended counter-argument of the cell theory. It was developed by Reichert, Strasberger, Sherrington, and Pavlov. It argues that the basic unit of life is the organism itself, suggesting that an organism came about from a cell that expanded.

4. Resolving power is the ability of an optical instrument like a microscope or a telescope to view objects that are close together as separate, abling the viewer to distinguish the two from each other.

A lamp that plugs into a wall socket draws energy which flows through a thin wire in the bulb causing it to glow. What energy tr

Softa [21]

Answer:

Electrical>thermal>light

Explanation:

Electrical energy refers to energy which is gotten from potential energy. This energy source could be a wall socket.

Thermal energy on the other hand refers to internal energy of a system where temperature is constant.

Light energy is made up of photons which transmits electromagnetic radiation which move in waves and become visible to human eye.

Therefore, the energy transformation taking place according to the question is option D.

Regular human body cells contain a total of 46 chromosomes. Therefore, because of meiosis, sperm cells contain ____ chromosomes.

Nataliya [291]

Regular human body cells or somatic cells have a total of 46 chromosomes. Therefore, because of meiosis, sperm cells, which are gametes or sex cells must contain 1/2 of the number of total chromosomes found within a somatic cell, to make sure that the chromosome number within an organism is maintained, this would be 23 in this case.
