Answer:
Explanation:The large molecules necessary for life that are built from smaller organic molecules are called biological macromolecules. There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell’s mass. Biological macromolecules are organic, meaning that they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, phosphorus, sulfur, and additional minor elements.
Carbon
It is often said that life is “carbon-based.” This means that carbon atoms, bonded to other carbon atoms or other elements, form the fundamental components of many, if not most, of the molecules found uniquely in living things. Other elements play important roles in biological molecules, but carbon certainly qualifies as the “foundation” element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role

<span>Weathering is a process where the rocks and minerals are dissolved and broken down on the surface of the earth.
After weathering, a process called erosion takes place which transports the bits of rocks and minerals. Weathering helps in smoothening of the sharp and rough rocks.
This process also helps in creating SOIL <span>due to the mixing of the tiny rock bits with the remains of animals and plants.</span></span>
Answer:
mitosis
Explanation:
Gametes are produced by mitosis (not meiosis) and after fertilization a diploid zygote is created. The single zygote cell never grows or divides my mitosis. It can only divide by meiosis to produce haploid cells once more, which then produce the main adult body.
Answer:
Explanation:
The high intensity disturbance is likely to reduce the diversity of species by creating environmental stress that can be responsible for exceeding the tolerance of many species the intolerant species is likely to be excluded. This will affect the equilibrium of the species diversity as non-adapting and intolerant species population may reduce or extinct.
For example, the fire is an ecological factor. The forest fire is utilized by some plants for the dispersal of seed by burning of the hard coat fruits like pine cones but it reduces the population of weed species. Thus this affect the equilibrium of the species diversity.
