Answer:
Differentiated cells refer to the specialized cells in multicellular organisms modified to carry out a particular function, such as transporting a certain substance or executing a specific task, while undifferentiated cells refer to the stem cells capable of giving rise to indefinitely more cells of the same type,.
The Hawaiian Islands were formed by a hot spot occurring in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving. So, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed.
What is hotspot?
"In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle".
What is Pacific plate ?
"The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km2 (40 million sq mi), it is the largest tectonic plate".

Answer:
Explanation:
The Hawaiian Emperor seamount chain is a well-known example of a large seamount and island chain created by hot-spot volcanism. ... The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate.
The best definition for a macromolecules is the most abundant elements found in living cells. The correct option is d.
A macromolecule, such as a protein or nucleicacid, is a very large molecule that is important in biophysical processes.
It is made up of thousands of atoms that are covalentlybonded. Many macromolecules are polymers composed of smaller molecules known as monomers.
Macromolecules are essentially polymers, which are long chains of molecular subunits known as monomers.
Long polymers are found in carbohydrates, proteins, and nucleic acids. They are classified as macromolecules due to their polymeric nature and large size.
Macromolecules are made up of monomers, which are single units joined together by covalent bonds to form larger polymers. The most abundant elements found in living cells are the best definition for macromolecules.
Thus, the correct option is d.

Your question seems incomplete, the missing options are:
a. a trace element
b. a vitamin
c. an organic molecule necessary for life
d. the most abundant elements found in living cells
Answer:
There are no answers to choose from.
Explanation:
However, the prefix macro- means big, so the word macromolecule means large molecule. Macromolecules are also known as the molecules of life, they all contain carbon. The four macromolecules are carbohydrates, proteins, lipids, and nucleic acid. Carbohydrates are used as a quick energy source, they can be broken up into monosaccharides, dsaccharides, and polysaccharides. Proteins are used as catalyst to help speed up chemical reactions. Lipids are also known as fats, they can either be saturated or unsaturated. Nucleic acids contain information.
Examples of each:
Carbohydrate- Gluten
Protein- Lactase
Lipid- butter, or oil
Nucleic Acid- DNA or RNA
Answer:
The serious cell: The plasmacyst or
Explanation:
The plasmacyst is a lymphocytic cell, since the plasmacyst is the maturation of the B lymphocyte.
This cell manufactures antibodies such as immunoglobulins and if it suffers metaplasia or malignancy these will be secreted in equal or greater quantity.
Living things are divided into five kingdoms: animal, plant, fungi, protist and monera. Living things are divided into five kingdoms: animal, plant, fungi, protist and monera.
Answer:
2) JG cells are present in the vasa recta.
Explanation:
The vasa recta is a web of the blood capillary which supply blood to the medulla region of a kidney due to its high permeability of solutes and water. It runs parallel to the loop of Henle. It does not composed of the juxtaglomerular cells (JG cells). The juxtaglomerular cells (JG cells) present in kidney which synthesise and stores enzyme renin. Thus, option 2) JG cells are present in the vasa recta is not a true statement.
