Answer:
B
Explanation:
a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one,
Answer:
A change in pH will cause many cellular processes to be disrupted because they affect the biomolecules (protein and nucleic acid) responsible for these processes.
Explanation:
pH refers to the degree of acidity or alkalinity. In a cell, the structures and processes that occur in them are impossible without the biomolecules, which are carbohydrate, protein, lipids and protein.
However, unfavorable conditions like a change in pH can cause the structure of some of these biomolecules to be affected. Proteins are made up of amino acids, which gives them their shape that is peculiar to their functioning. Also, nucleic acids such as DNA are composed of nucleotides responsible for their functioning.
A change in pH will cause the bonds of the protein to be disrupted, hence altering its shape and ultimately its functioning. Likewise, the hydrogen bonds in the DNA will be broken in the presence of a high pH causing the DNA to be dysfunctional.
When these biomolecules are affected, the vital functions that they perform in a cell, which is key to the cell's survival are disrupted) are likewise affected. Therefore, the cell is affected negatively.
Answer: d)All of the above
Explanation: Competitive effect is defined as the interaction created between species or organism , which usually results in negative situation. There are certain condition for the competition such as supply of any resource in limited quantity, etc.So competition is also invoked by the density of the species present and in order to exist in an ecosystem and thus there is the high chances of the overlapping of species as well.
Therefore,option(d) is the correct option.
CLOUD FORMATION, he said it under the question but i put it here so it would be easier too find
Answer:
a) not accompanied by purging
Explanation:
- If a person has episodes of uncontrollable eating then the person is said to have a problem of binge eating.
- When a person shows a tendency of frequent and recurring binge eating then the person is said to have binge eating disorder.
- Binge eating disorder is differentiated from another similar problem which is known as bulimia nervosa.
- In the case of binge eating disorder a person has a tendency of binge eating but without purging, unlike bulimia nervosa where purging is a characteristic feature.
- Purging is an attempt to get rid of the excess food consumed and this attempt is not made in case of binge eating.
