How does the distance from the mainland affect the number of species?
Answer:
Area increases diversity because a larger plot is likely to have more habitats, hence niches, to support a greater variety of species. How does the distance from the mainland affect the number of species? The farther from the mainland you go, the less species richness.

Explanation:
Explain why diversity is important for the survival of a species?
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.

Budding. Organisms reproduce by splitting off new individuals from existing ones, resulting in genetically identical parent and daughter organisms.
What do you mean budding?Budding is an asexual mode of organism formation. A new organism is formed from a small part of the parent's body during this process. A newly formed bud separates to form a new organism. The newly formed organism remains attached as it grows.To create an advantageous variety (cultivar) and rootstock combination, a single bud from a desirable plant is inserted into an opening in the bark of a compatible rootstock.Budding, also known as bud grafting, is a type of vegetative or clonal plant propagation that produces an exact replica of the parent plant. Chip budding and T budding are two slightly different methods of budding.To learn more about : Budding

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.
What are proteins?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.

A).blood
B).brain
C.)eye
D.)leukocyte
E.)muscle
Among the listed components, the brain and the eye are the organs. Skeletal muscles are also classified as organs.
What are the levels of the organization?In anatomical studies of an individual, the classification of the hierarchy of the structures of the organism is useful for the estimation of the complexity level of the individual.
The chemical level of organization is the first level of organization where atoms are combined for the formation of molecules. Molecules are combined to form macromolecules.
Different types of macromolecules result in the cellular level of organization. The macromolecules that are the components of cells are called biomolecules.
Cells of the same kind are combined and work in the association as a tissue, for example, nerve cells form nerve tissue.
These tissues of similar functions combine to form organs. For example, multiple nerve tissues are combined to form the brain and the spinal cord.
The nerve cells, nerve tissues, spinal cord, and brain are studied together as an organ system called the nervous system. Several organ systems like this are grouped to form an individual.
Therefore, the brain and eye are examples of organs.

Bromothymol blue (BTB) is a chemical indicator for carbon dioxide (CO2). In the presence of carbon dioxide (CO2), BTB turns from blue to yellow. An aquatic plant was placed into two test tubes containing BTB, and the test tubes were closed with a stopper. Then, one test tube was placed in the dark, and the other test tube was placed in direct sunlight. The test tube in sunlight stayed blue indicating no CO2 was present, while the test tube in the dark changed to yellow. Which statement best explains why the solution in the test tube placed in the dark changed to yellow?
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.
what is different between leaching and erosion
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.
What do you mean by soil erosion?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.

Many different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis?
silent
missense
nonsense
deletion
Answer:
Deletion
Explanation:
I think it is the last one
Deletion
If it really helped please give me brainliest
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.
