Erosion is the natural process by which soil / rock are removed from the Earth's surface by exogenetic processes whereas Leaching is the removal of soluble material from soil or other material by percolating water.

Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, and animals.

Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.

Removing trees and plants, plowing fields, and overgrazing by livestock disrupts roots that stabilize sediment and soil. These human activities can increase erosion rates 10 to 100 times that of non-human geologic processes.

Answer:

The importance of genetic diversity. More specifically, genetic diversity can be a species natural defence system against disease and survival even under extreme weather conditions but more importantly, genetic diversity can help weed out unfavourable traits in species which maximises opportunities for thriving in any environment². hoped it helped.

Explanation:

Increased genetic diversity leads to increased chance of species survival. Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity.

1. The reader knows that the boy is about to break up with his girlfriend, but the girlfriend doesn't know. That is dramatic irony

because  Dramatic Irony appears when the readers know something the character does not know. For example, in scary stories, the reader often knows where the bad guy hides, but the character does not. As the character approaches the hiding spot, the readers may experience heightened suspense due to the dramatic irony.

2.Dave's blood pressure medicine game him a heart attack.  That is

Situational irony.

Situational Irony happens when something happens that the reader does not expect to happen. For example, if someone robs a thief in a story, that portrays situational irony. Readers would not expect a thief who robs others to be the one who gets robbed.

3. "Oh, great! I'm so glad it's raining, and I forgot my umbrella."  That is Verbal irony

Verbal Irony occurs when a character says one thing but means something else. This type of irony is also known as sarcasm. For example, a parent might reveal verbal irony, or sarcasm, by showing up at the door of an extremely messy room and commenting, "I've never seen your room this clean before! You are grounded." Clearly, the parent revealed sarcasm when commenting about the cleanliness of the room.

The basic unit of life has to be a living thing, atoms aren't alive yet they make up cells, which are alive. However, atoms are building blocks of everything. Yet cells themselves are living, therefore are the building blocks of all forms of life.

Atoms are smaller than cells. Yet cells are the building blocks of life because atoms are not living, and living organisms are made up of cells because cells are living components.

Cells are the basic components of living organisms. Atoms are the basic and smallest unit of matter that is nonliving.

Since atoms do not have life, they cannot be the fundamental building block of life; nonetheless, they do makeup living cells.

Atoms are the fundamental units of matter, nevertheless. However, because cells are living entities in and of themselves, they serve as the foundation for all life.

Thus, cells are larger than atoms. However, as atoms are not alive, cells are the fundamental unit of life, and since cells are living entities, they are the foundation of all living things.

Here are some atoms that can be found in protein hydrogen, carbon, sulfur, oxygen, and nitrogen.

Hope this helps :)

Protein has been the organic molecule that are polymers of amino acids. Proteins are composed of five major atoms of carbon, oxygen, hydrogen, sulfur, and nitrogen.

Proteins are the macromolecules that are polymers of amino acids. The monomeric units (amino acids) of the protein molecule are linked by the polypeptide bonds. They are involved in the majority of the activities that are crucial for the body to function.

The amino acid, the monomer has been composed of the carboxylic and the amine group that includes the atoms of nitrogen, carbon, oxygen, and hydrogen while the substitutional group may include the sulfur atoms. The carbon is the central atom attached to the other molecules.

Therefore, hydrogen, nitrogen, carbon, sulfur, and oxygen are the atoms of proteins.

Answer:

Explanation:

Although no options was given, the explanation below should give detail explanation.

The Chemical  reactants(  internal factors) for the process of photosynthesis are C02 and H20, and enzymes. Other external factors  are sunlight and chlorophyll.Therefore for a plant to undergo photosynthesis these reactants must be present in the presence of sunlight.

In the present scenario the plant in the test tube exposed to sunlight must used up the C02  with water and exposed sunlight to produce O2 -the by products and  CHO,Protein and Lipids in plants.

Since the C02 has  metabolised,no CO2 would be present in the test tube  of the plant and the water, hence BTB is negative,blue- no C02.

However,the plants in the dark lacks  the supply  of  sunlight therefore no photosynthesis could occur.Consequentially the C02 is not metabolized,and its concentration is high in the leaf in the test tube placed in the dark.This is indicated as yellow positive by the BTB which change from Blue to yellow.

A nonsense mutation is one mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence.

Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene.

The CFTR gene codes for the CFTR protein whose function is as an anion   channel (chloride ion) which helps control the movement of water in and out of the membrane of cells that are specialized to produce mucus, sweat, saliva, tears and digestive enzymes

When CFTR protein is defective  or absent, thick, sticky mucus accumulates in these cells, obstructing the airways and glands.

The most common mutation of the CFTR gene is a deletion whereby the codon for the amino avid phenylalanine is deleted resulting in the production of a defective CFTR protein.

Another form of mutation in the CFTR gene is a nonsense mutation in which a stop codon is inserted in the middle of the gene resulting in the production of a shortened CFTR protein, which is then degraded by the cell.

Therefore, a nonsense mutation in the CFTR gene leads to cystic fibrosis by causing translation to end earlier in the gene sequence.
