This through the process of mitosis. Mitosis is a type of cell division which responds to the multiplication of cells or more specifically the duplication of diploid cells. Diploid cells contain the complete DNA number in contrast to the haploid cells.
Answer: B
Explanation:
The observed differences between the groups most likely resulted from differences in the ability of the seedlings to produce amino acids.
Differences observed in the plant groups would most likely be due to their differing abilities to produce glucose, a monomer that forms cellulose and other sugars vital for plant functions. Other options such as amino acids, cellulose and DNA also play crucial roles in the plant's life processes.
The observed differences between the groups most likely resulted from differences in the ability of the seedlings to produce glucose. Glucose is a monosaccharide, or a simple sugar, that serves as the primary fuel for plants. Glucose monomers form structures like cellulose, which primarily make up a plant's cell wall, providing it with structural support. Glucose is also involved in the formation of other types of sugars such as sucrose and lactose when combined with fructose and galactose, respectively.
However, it's important to note that all the options given - glucose, amino acids, cellulose, and DNA - are monomers or polymers that play vital roles in the life functions of a plant. Amino acids are the building blocks of proteins, cellulose is a structural polysaccharide composed of glucose units, and DNA holds the genetic information of the plant.

Ground water pollution can be caused by chemical spills, road salt, pesticides, fertilizers.
Groundwater pollution also described as groundwater contamination happens when pollutants are discharged to the ground and make their process down into groundwater. This type of water pollution can also happen commonly due to the appearance of an insignificant and unwanted component, contaminant or contamination in the groundwater, in which event it is more likely related to as contagion rather than pollution.
The cell membrane is also called selectively permeable membrane for its composition, it is composed of amphipathic lipid, protein and small amount of cholesterol which form a bilayer structure allow only specific substance.
The cell membrane is a thin selectively semi-permeable membrane and act as an outer covering surrounding cell cytoplasm, Proteins and lipids are the major components.
The major lipids are phospholipid, which form a semi-permeable lipid bilayer which have both hydrophilic or water loving head group and hydrophobic or water hating tail group and form bilayer structure.
Hence both group can interact with polar and non polar molecule individually called as amphipathic in nature, Some organelles like nucleus and mitochondria also have its own cell membrane.
The proteins are peripheral, extrinsic and intrinsic type and the function of cell membrane is to protect the cell and maintain the structural integrity of the internal environment of the cell.

The cell membrane is also called selectively permeable membrane for the sole reason being it is selective in nature.
It forms a physical barrier and as a barrier between the cell and the external environment as it allows only selected necessary molecules to pass through it and at the same time prevents entry of unwanted / unnecessary substances.
It also regulates the entry and exit of molecules into and out of the cell.
The cell membrane permits the entry of vital molecules like
water, oxygen, amino acids and glucose into the cell as they are crucial for various life processes and at the same time metabolic waste products are expelled through the cell membrane.
