How do wetlands improve water quality in an ecosystem?
tankabanditka [31]
One of the most important benefits that wetlands provide is their capacity to maintain and improve water quality. When healthy, wetlands have a rich natural diversity of plants and animals. These can act as filtering systems, removing sediment, nutrients and pollutants from water.

Which of the following is an example of post-transcriptional control of gene expression?
konstantin123 [22]

Answer:

Option (c).

Explanation:

Transcription may be defined as the process of formation of RNA molecule from the template DNA with the help of enzymes and transcription factors. The transcription occurs in 5' to 3' direction.

Post trancriptional modification occurs in the RNA molecule that plays an important role in transcription as well as translation. The introns are removed from the RNA transcript and exons joined together is known as splicing. The alternative splicing occurs in which different protein isoforms are formed by the single exons.

Thus, the correct answer is option (c).

We breathe more quickly and deeply when we exercise. Why does this make sense? Select all that apply. a) Because when we exercis
storchak [24]

Answer:

a) Because when we exercise, we hydrolyze more ATP to ADP and Pi, and O2 is necessary for the hydrolysis, so we increase our intake of oxygen.

c) Because when we exercise, we produce more CO2 and increased ventilation is necessary to rid ourselves of CO2.

d) Because when we exercise, we use more ATP, and additional O2 is necessary to generate sufficient ATP.

Explanation:

During exercise , our body needs more energy in the form of ATP. This ATP comes from break down of food materials in the mitochondria of the cell during cellular respiration. With the addition of oxygen, more ATP is produced during respiration and this ATP is used by the body. With ATP, carbon dioxide is produced as a waste material which can be removed by exhaled out during breathing.

Pepsi [2]

Answer: The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties.

Explanation:

Starch and Cellulose flare both polysaccharides which are constructed from the same monomer called glucose. The functions they provide in plants are different which includes the following:

- STARCH is used by plants for energy storage because unlike Cellulose, it's formed from glucose units( oriented in the same direction) connected by alpha linkages which can form compact structures that can easily be broken down.

- Cellulose provides structural support for plant cell wall because unlike Starch, it's formed from glucose units( which rotates 180 degrees around the axis of the polymer backbone chain) connected by beta linkages. This pattern gives Cellulose it's rigid features as is allows for hydrogen bonding between two molecules of Cellulose.

Therefore the statement that best describes why starch and cellulose provide different functions in plants is that (The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties).
