Cell division, torso axis formation, tissue and organ development are all part of development, and cell differentiation refers to acquiring a final cell type identity.
What is cell division?The process by which a parent cell divides into two daughter cells is known as cell division.
Cell division is usually part of a larger cell cycle during which the cell grows and replicates its chromosomes before dividing.
Cell division occurs in two stages: mitosis and meiosis. When most people say "cell division," they're referring to mitosis, the process of creating new body cells.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
Multicellular organisms form in a variety of ways, including cell division and the aggregation of many single cells. Colonial organisms form when many identical individuals band together to form a colony.
Thus, this way, organisms with many cell types develop from a single cell.

what's mitosis and meiosis?
Answer:
MITOSIS AND MEIOSIS*Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. ... During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
What meiosis means?Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.
What is mitosis explain?Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
What is meiosis important?Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
What is Mitosis important?Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

Are any change in the sequence of bases in DNA or RNA that can cause by mutagen or can happen spontaneously in the cell
Answer:
MUTATION
Explanation:
Mutation is a change or alteration in the genetic sequence of a DNA or RNA (nucleic acid) that are induced by a chemical substance called MUTAGEN or by a spontaneous occurrence. Mutation are of different types depending on how it occurs in the cell. A mutation can be deletion (removal), substitution (replacement), insertion (addition) etc.
Based on this question that states that "any change in the sequence of bases in DNA or RNA that can be caused by mutagen or can happen spontaneously in the cell", the process of MUTATION is being described.

A
Explanation:
Thick clouds can trap lots of heat. This has a warming effect on earth.
Answer:
B.. More evaporation due to warmer temperatures increases water vapor, forming high, thin clouds

Without genetic variation, natural selection would not be possible. Explain why.
Answer:
Without genetic variation, natural selection is only able to grow the number of allelomorphs that previously exited in the population. Natural selection occurs through an interaction between the environment and the variability of the individual organisms making up a population.

Explain the mechanism of ventilation in human lungs (you should talk about the diaphragm, abdominal muscles and rib cage and intercostal muscles)
Answer: When the diaphragm contracts, it moves inferiorly toward the abdominal cavity, creating a larger thoracic cavity and more space for the lungs. Contraction of the external intercostal muscles moves the ribs upward and outward, causing the rib cage to expand, which increases the volume of the thoracic cavity.
The movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.
The ventilation in human lungs or pulmonary ventilation is defined as the process of intake of air during inhalation, and expiration as the release out of air. It is also termed as breathing.
What is the mechanism of pulmonary ventilation?The lungs are present in the thoracic cavity, with the diaphragm below the lungs separating the thoracic cavity from the abdominal cavity. The rib cage is present outside lungs and prevent them.
Inhalation process in pulmonary ventilationThe inhalation is the process of taking in air. The increase in the volume of lungs results in the increased movement of diaphragm to the abdominal cavity.
The intercostal muscles move upwards and the rib cage move outwards. Thus, the air is inhaled in the system.
Exhalation process in pulmonary ventilationThe exhalation of air is performed antagonist to the inhalation. The relaxation of diaphragm and the movement of rib cage results in the decreased volume of the lungs, and the air is expelled.
Thus, the movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.

Regan is trying to determine if an unknown element is a metal. She does not want to damage or change the physical appearance of the element in any way. Design an experiment that could determine if the mystery element is a metal without changing its appearance.
Explanation:
Well, one could use a magnet to see if it's ferrous. One could melt it to check which type it is, use a metal detector, or just use their senses: If it dings or clinks like metal, and feels like it’s texture. If it polishes with metal polish, is reflective, can be shaped or shape when heated… It usually is a metal. If it rusts, or oxidizes, it is or contains metal. If it “smells" like metal, most likely, it is metal. Finally, if it walks like metal, and quacks like metal, most likely we have a metal

let me know if it's correct or not, these were the only ones I could think of.
Few natural elements have a greater density than gold are plutonium, neptunium, and osmium.
What is an element?
An element is define as a type of substance that is impossible to break into smaller pieces by the help of chemical process. There are several rules that should be followed at the time of assinging name of the elements. The first rule is name of the element is not a proper noun. The second rule is the symbols of the element that must be of one or more than one symbol.
Density is define as the mass per unit volume it means that 1 kg mass present in 1 meter cube is called density, density is also states that the how compact an material.
Mathematically
Density = mass/volume
S.I unit of density is kg/m^3
Density is higher in solid as compare to liquid and density of liquid is higher than gas so density is in order of SOLID>LIQUID>GAS. So we know that solid is compact in nature as compare to liquid and gas.
Therefore, Few natural elements have a greater density than gold are plutonium, neptunium, and osmium.
