Note that mitosis is also valuable for repairing damaged tissue, replacing worn out cells, growing, and developing, not just asexual reproduction.
Asexual reproduction does not occur by meiosis.
Final answer:
Mitosis is a form of asexual reproduction because it allows a single cell to divide and produce two genetically identical daughter cells. There is no exchange of genetic material, making the offspring an exact copy of the parent.
Explanation:
Mitosis is considered a form of asexual reproduction because it enables a single cell to divide and produce two daughter cells that are genetically identical to the parent cell. In asexual reproduction, there is no exchange of genetic material, thus ensuring that the offspring is an exact copy of the parent. This is the main reason why mitosis, with its mechanism of copying and separating chromosomes, is classified as asexual reproduction.
For instance, a bacterium reproduces by mitosis; first, it duplicates its DNA and then divides into two cells. Each of these two cells has exactly the same DNA as the parent bacterium.

Technology is built to give means, tools, and machinery for the preservation of the environment's resources from the damaging effects of climate change and global warming, and the environment in turn provides the materials, which is how technology and the environment are interdependent.
What is global warming ?
The gradual increase in the planet's surface temperature is known as global warming. Although this warming trend has been around for a while, the burning of fossil fuels has greatly accelerated its pace over the past century. The amount of fossil fuels burned has increased along with the size of the human population.
The two main ways that these technologies have harmed our planet are through pollution and the depletion of natural resources. When dangerous or excessive levels of gases like carbon dioxide, carbon monoxide, sulfur dioxide, nitric oxide, and methane are released into the earth's atmosphere, air pollution results.
Technology and society have a reciprocal interaction. Technological advancement shapes society, while technological advancement drives it.
Thus, the environment's resources from the damaging effects of climate change and global warming, and the environment in turn provides the materials.

The sky is not solid, not liquid but of gas. It is also called the atmosphere, one of the important spheres on earth that influences the climate –temperature, humidity, precipitation, atmospheric pressure, and the biotic community as a whole. The atmosphere or the sky is composed of many layers and is responsible to protecting the living organisms of the earth against the deadly ultraviolet rays and other strong radiation coming from the sun.
Answer:
gas
Explanation:
The sky is not a solid body, nor does it have all of the same the physical properties of a solid body. In terms of its behavior, physically a gas is much closer to a liquid than a solid. If you drop the temperature of the atmosphere quick enough and low enough it can become a solid.

Net ionic equation:
Ca⁺²(aq) + CO²⁻₃(aq) → CaCO₃(s)
Explanation:
Chemical equation:
K₂CO₃ + CaCl₂ → KCl + CaCO₃
Balance chemical equation:
K₂CO₃(aq) + CaCl₂(aq) → 2KCl(aq) + CaCO₃(s)
Ionic equation:
2K⁺(aq) + CO²⁻₃(aq) + Ca⁺²(aq) + 2Cl⁻(aq) → 2K⁺(aq) + 2Cl⁻(aq) + CaCO₃(s)
Net ionic equation:
CO²⁻₃(aq) + Ca⁺²(aq) → CaCO₃(s)
The K⁺(aq) and Cl⁻ (aq) are spectator ions that's why these are not written in net ionic equation. The CaCO₃ can not be splitted into ions because it is present in solid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
Final answer:
The net ionic equation for the reaction between K2CO3 and CaCl2 is Ca2+(aq) + CO3^2-(aq) --> CaCO3(s). This is obtained after removing the spectator ions (K+ and Cl-) from the full ionic equation.
Explanation:
The subject of discussion is the net ionic equation for the given chemical reaction between K2CO3(aq) and CaCl2(aq). An ionic equation represents the ions that are present in a chemical reaction, and a net ionic equation only shows the ions that actually participate in the reaction.
To form the net ionic equation, we first write the complete ionic equation. In this case, K2CO3(aq) breaks down into 2 K+(aq) + CO3^2-(aq), and CaCl2(aq) breaks down into Ca2+(aq) + 2 Cl-(aq). The products would be 2 K+(aq) + 2 Cl-(aq) + CaCO3(s).
The net ionic equation is then formed by canceling out the spectator ions (ions that do not participate in the reaction). Here, the spectator ions are K+ and Cl-. So, the net ionic equation is: Ca2+(aq) + CO3^2-(aq) --> CaCO3(s)
