Answer: A) reproductive cloning of humans.

Biotechnology is the broad discipline of biology in which living organisms and their products are manipulated in such a way that they can be utilized for the purpose of human society. The antibiotics, hormones, industrial products and genetically modified organisms are the products of biotechnology.

Reproductive cloning of humans cannot be considered as the advantage of biotechnology because of the following reasons:

1. Difficulty in establishing identity:  We human beings differ from each other on the basis of differences in the physical and genetic features. If the clones are developed than it would become difficult to assign identity to a person.  

2. It is against ethics: The human beings and other organisms are natural creation the human induced technology to develop a life can be against the nature's regulation. Therefore, human cloning is against the ethics.

3. It can be costly and technology efficient process: The technology used to create human clone can be expensive and time consuming.

In glycolysis, pyruvate, ATP, and NADH are produced. The lactic acid fermentation process uses the NADH molecule from glycolysis
jekas [21]

Answer:

Explanation:

<em>Fermentation does not involve an electron transport system, and no ATP is made by the fermentation process directly. Fermenters make very little ATP—only two ATP molecules per glucose molecule during glycolysis. ... During lactic acid fermentation, pyruvate accepts electrons from NADH and is reduced to lactic acid.</em>

Based on the information in the table, which of the following changes is least likely to produce a phenotypic
yaroslaw [1]

GAU to GAC​ is least likely to change phenotype of an organism.

<h3><u>Explanation</u>:</h3>

Phenotype of an organism is defined as the physical characteristics of an organism. This phenotype is dependent on the genotype of the organisms. This means the phenotypic characters are actually the expressions of the genes of the organisms. Now the genes are expressed in form of codons that are the three nitrogen base sequences. Each codon codes for a particular amino acid which in turn polymerises to from the protein which actually forms the phenotype of the organism.

Now there are 20 amino acids and 64 codons. Thus there are more than 1 codons for a single amino acid. So, if a codon is replaced by another codon which codes for same amino acid, then the phenotype is least likely to be affected.

Both the GAU and  GAC​ codes for aspartic acid. So the phenotype won't be affected much by this mutation

The row of energy in a grassland ecosystem is shown
bixtya [17]

The populations with the trophic levels that receive the least amount of the total energy from the grass would be Hognose snakes and owls.

<h3>Trophic Level</h3>

The higher we move up a trophic level, the lower the amount of energy transferred from the previous levels.

More precisely put, only about 10% of the total energy available at one trophic level is transferred to the next while the rest is lost as heat to the surrounding.

In this case, Hognose snakes and owls represent the two highest trophic levels in the ecosystem. Thus, their populations would receive the lowest amount of energy from the producer, the grass.
