When two solutions are separated by the membrane through which water can pass but starch cannot, the osmosis will occur.

Osmosis is described as the spontaneous movement of water through membrane from a region of lower solute concentration into a region of higher solute concentration. Water movement tends to equalize the solute concentrations on the two sides.

Answer:

Water will move from its region of high concentration towards the starch

Explanation:

As given in the problem statement , water can pass through the membrane but starch cannot pass through it. Thus, water will start permeating through the permeable membrane governed by the concept of osmosis where fluid at higher concentration starts moving towards the low concentration chamber.

Thus, water being at higher concentration on one side starts moving from its side to the side of starch and hence the starch solution level will rise while the level of water will lower down.

Mitosis is a process used for normal growth and development. Explain how and why a mutation in a BRCA gene may affect the cell c
Romashka [77]

Answer:

The BRCA gene is a tumor-suppressor gene found in the breast; to be more specific, it produces proteins that suppress cancerous activities/abnormal growth in the body. A mutation in a BRCA gene would allow these abnormal growth activities to go unchecked and thus increase the rate of mitosis. Cell cycle checkpoints would significantly be worse at their jobs of checking and correcting for errors during the cell cycle. Tumors would result as well, as cancerous growth continues, and the tumor can become metastatic.

Svetach [21]
<span>The answer is B.mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein. According to the central dogma of molecular biology, DNA sequence specifies RNA sequence which specifies protein sequence. DNA sequence is first copied into mRNA sequence during transcription. Later, during translation, mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein</span>

How is the oxygen cycle disturbed by deforestation
eimsori [14]

Answer:

If deforestation is disturbed then the photosynthesis cycle is disturbed, which results in the oxygen cycle being affected. With a decrease in trees, a decrease in photosynthesis occurs, which cause a decline in the oxygen cycle. A decline in the oxygen cycle results in more polluted air.

Explanation:

Without trees, humans would not be able survive because the air would be unsuitable for breathing. Due to deforestation, there would be fewer trees to "clean" the air. Deforestation is the action or process of clearing of forests, or the state of having been cleared of forests.

Trees and plants, in general, produce energy for growth using a process known as photosynthesis. Using light, water and carbon dioxide, a plant produces energy in the form of sugar and releases oxygen into the air.

Deforestation, as well as a rise in the emissions and our global temperature, affects the air that we breathe. This is because all trees take in carbon dioxide and other pollutants which are known to cause a lot of problems in the atmosphere and to humans. This inevitably results in people breathing dirtier and more polluted air that normally wouldn't happen.  

Long-term exposure to polluted air can have permanent health effects such as: Accelerated aging of the lungs. Loss of lung capacity and decreased lung function. Development of diseases such as asthma, bronchitis, emphysema, and possibly cancer.

Trees are responsible for taking the carbon from the atmosphere through photosynthesis in order to make energy. This carbon is then either transferred into oxygen and released into the air by respiration or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly higher amounts of carbon dioxide in the air and lower amounts of oxygen. This bad quality air would also be full of airborne particles and pollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide.

In addition to the decrease of oxygen in the atmosphere, it would allow excessive amounts of carbon dioxide to remain. In the short term, since CO2 is one of the major greenhouse gases, it will undoubtedly lead to higher global temperatures which, in turn, would quicken the melting of the polar ice caps.
