Answer:

There are 2 types of resources - renewable and non renewable

Advantages:

Renewable resources:

1. As the name suggests, it can be renewed that means we could never run out of this source or its abundance will never end.

2. The cost and efficiency of this resource is totally dependent on the present technology. It can be produced locally with the technology used.

Non renewable resources:

1. They are very profitable in business.

2. They are easy to use and cost efficient.

Disadvantages:

Renewable resources:

1. The upfront and installation cost is much higher.

2. They depend on natural factors like sunlight, wind, water which are not constant. Thus they don’t have constant supply.

Non renewable resources

1. They lead into the emission of green house gases which pollutes the environment and causes acid rain, fire hazards etc.

2. They are limited in nature, once exhausted, they will take thousands of years to get ready for use.

Reporte la síntesis de proteínas

damaskus [11]

Answer:

La síntesis de proteínas se realiza en los ribosomas situados en el citoplasma celular. En el proceso de síntesis, los aminoácidos son transportados por ARN de transferencia correspondiente para cada aminoácido hasta el ARN mensajero donde se unen en la posición adecuada para formar las nuevas proteínas.

An individual with Huntington disease has two normal parents. What are plausible explanations for this pattern of inheritance? C

Vitek1552 [10]

Answer and Explanation:

The Huntington disease is caused by a mutation in the gene that codifies for the Huntingtin protein (Htt). The mutation produces an altered form of the protein leading to the neuron´s death in certain areas of the brain.

The Huntington disease characterizes for being,

Hereditary, passing from generation to generation. To express the disease, a person must have been born with an altered gene.

Autosomal, affecting men and women equally, because the mutated gene is located on an autosomal chromosome.

Dominant, which means that by getting only one copy of the altered gene coming from any of the parents, the receiving person will express the disease. The mutation in the gene dominates over the normal gene copy.

Expressed by heterozygosis. Most people affected by the disease are heterozygous, with a normal copy and a mutated copy.

There are just a few cases all around the world (3% approximately) in which the disease is expressed with no family history. The progenitors are not affected by the mutation. These cases are very rare and are called "de-novo" mutations. A new mutation is spontaneously produced and it is not inherited from any of the parentals. It consists of an increase in the number of CAG repetitions. In a normal person, the number of CAG repetitions is less than 35. When there are 40 or more repetitions it occurs the disease. But when there are between 35 and 39 repetitions, the penetrance of the disease is incomplete. This is a "gray zone". Those alleles that fall in the gray zone are unstable and might produce the HD. Individuals with these unstable alleles have a tendency to increase the number of repetitions from generation to generation until the number reaches 40 repetitions and the person expresses the disease. This usually occurs in the paternal germinal line, as it is particularly unstable in sperm and probably meiosis greatly affects their instability, causing an increase in the number of CAG repeats.

Cellular respiration and fermentation both. . A. begin with the breakdown of glucose in glycolysis. . B.produce the same number

Rus_ich [418]

The correct answer is:

A. begin with the breakdown of glucose in glycolysis.

Explanation:

They both begin with a sequence of reactions known as glycolysis, which breaks glucose particles into smaller pyruvate molecules. They are also related in that through both processes, ATP is generated for the cell to use. Glycolysis is the metabolic pathway that transforms glucose C6H12O6, into pyruvate, CH3COCOO− + H+. The free energy delivered in this process is applied to form the high-energy molecules ATP and NADH .
