Answer:
denatured
Explanation:
Each enzyme works best at their own pH, so at high pH the enzyme is said to be denatured, changing shape. The substrate is no longer able to bind to the active site.
Answer: A( adenine) G (Guanine) C (Cytosine) T (Thymine) U (Uracil)
Why? Nucleic acids are polynucleotides—that is, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. ... Each nucleic acid contains four of five possible nitrogen-containing bases: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U).
1. Once a dam is constructed, electricity can be produced at a constant rate.
<span>2. If electricity is not needed, the sluice gates can be shut, stopping electricity generation. The water can be saved for use another time when electricity demand is high. </span>
<span>3. Dams are designed to last many decades and so can contribute to the generation of electricity for many years / decades. </span>
<span>4. The lake that forms behind the dam can be used for water sports and leisure / pleasure activities. Often large dams become tourist attractions in their own right. </span><span> </span>
<span>5. The build up of water in the lake means that energy can be stored until needed, when the water is released to produce electricity.
6</span><span>. When in use, electricity produced by dam systems do not produce green house gases. They do not pollute the atmosphere </span>
<span>DISADVANATGES: </span>
<span>1. Dams are extremely expensive to build and must be built to a very high</span>
<span>2. The high cost of dam construction means that they must operate for many decades to become profitable. </span>
<span>3. The flooding of large areas of land means that the natural environment is destroyed. </span>
<span>4. People living in villages and towns that are in the valley to be flooded, must move out. This means that they lose their farms and businesses. In some countries, people are forcibly removed so that hydro-power schemes can go ahead. </span>
<span>5. Although modern planning and design of dams is good, in the past old dams have been known to be breached (the dam gives under the weight of water in the lake). This has led to deaths and flooding. </span>
<span>6. Dams built blocking the progress of a river in one country usually means that the water supply from the same river in the following country is out of their control. This can lead to serious problems between neighbouring countries. </span>
<span>7 Building a large dam alters the natural water table level. For example, the building of the Aswan Dam in Egypt has altered the level of the water table. This is slowly leading to damage of many of its ancient monuments as salts and destructive minerals are deposited in the stone work from ‘rising damp’ caused by the changing water table level.</span>
Complete question:
If the recessive allele for cystic fibrosis is represented as c, classify the following genotypes as homozygous dominant, homozygous recessive, or carriers: CC,Cc, and cc. State which one has the phenotype of cystic fibrosis.
Answer:
CC - homozygous dominant
cc - homozygous recessive
Cc - carriers
cc will have the phenotype
Explanation:
Cystic fibrosis is an autosomal recessive disorder that affects the production of mucus in the body, primarily affecting the lungs and digestive system.
Because it is autosomal recessive, an affected individual needs to inherit 2 copies of the faulty gene. The presence of just one normal copy of the gene is sufficient not to cause the disease
In genetics, the dominant allele is usually displayed as a capital letter and the recessive as a small letter. Homozygous means someone has 2 copies of the same allele, heterozygous means they have different alleles. Therefore, CC - homozygous dominant, cc - homozygous recessive, and Cc - carriers. Only those with a cc genotype will be affected, as the presence of one dominant allele is enough to block the phenotype
