There is a nature law every actions has reaction. So when human being impact the environment in any way such as pollution, global warming etc., environment results to rise in the sea level or increase of disease that results to the death of the human beings.
Environment is defined as a sum total of all the non-living or living elements and their effects that influence human life.
Protect our water supply and keep our air cleaner and awareness in the people is only way to protect the environment. Other main important method to protect the environment is reuse, reduce, recycle.

The kingdom Animalia, which belongs to the Eukarya domain, is known for having organisms with cells that do not have cell walls. Other kingdoms, like Plantae and Fungi, typically have cell walls.
The kingdom known for containing organisms with cells that lack cell walls is the Animalia kingdom which exists within the Eukarya domain. In the classification of life, three main domains exist: Bacteria, Archaea, and Eukarya. The first two mainly include prokaryotic organisms which usually have cell walls. The Eukarya domain includes four kingdoms: Animalia, Plantae, Fungi, and Protista. Among these, it's typical for Plantae and Fungi to exhibit cell walls. Conversely, Animalia comprised of animals, do not have cell walls surrounding their cells. Their cells are surrounded by a plasma membrane which offers flexibility and aids in movement and interaction with the environment. This characteristic is one of the key distinguishers of the Animalia kingdom from other kingdoms.

+1-1+2-2+3-3+4-4
Answer:
+1, -1.
Explanation:
Ions may be defined as the molecules that contains charge in their structure. Ions that carry positive change is known as cations and ions that carry negative charge are known as anions.
The velency may be defined as the number of electrons present in the outermost shell. The +1 has the highest tendency to form cations because a little amount of ionization enthalpy is required to remove the 1 electrons. The -1 has highest tendency to form anion as it has the most negative electron gain enthalpy and can easily gains an electron.
Thus, the answer is +1 and -1.
If human sperm and eggs were produced by mitosis instead of meiosis, they would be diploid cells, possibly resulting in a zygote with an excess of chromosomes. This imbalance could lead to nonviable offspring and developmental complications, as necessary components for early development are only present in the egg cell.
Currently, human sperm and eggs are produced by the process of
meiosis
, which results in
haploid cells
that contain half the number of chromosomes as the parent cell. If, hypothetically, sperm and eggs were produced by mitosis, they would be
diploid cells
with a full set of chromosomes similar to normal body cells. With such a change, sexual reproduction, as we understand it, could not occur, as the fertilization event would result in a zygote with four sets of chromosomes, creating a significant imbalance in genetic material. This could potentially lead to numerous complications and abnormalities in the offspring, likely making them nonviable. Additionally, critical components necessary for early development are present in the cytoplasm of the egg cell, without which, no subsequent development would occur. In conclusion, the production of sperm and egg cells via mitosis instead of meiosis would fundamentally alter human reproduction and could potentially lead to severe problems in offspring development.
