Genetically modified (GM) foods make it possible to produce more food on less land. However,
Nuetrik [128]

Explanation:

<u>d. The high cost of GM seeds may force small farmers out of business.</u>

Modified crops have been patented and marketed by private companies. The seeds produced have been sold to many small farmers with the promise of improved yields and hardy crop. However, the high cost of repurchasing seeds may often be prohibitive to small farmers hoping to keep their businesses afloat.

Further Explanation:

Genetically modified species (GMs) have their DNA altered or improved through genetic engineering methods usually GMOs include modifications in DNA through the incorporation of genes from all creatures such as plants, fungi, viruses and animals. These are referred to as transgenic organisms, which lead to several developments by increasing global food security which is the supply of food for the entire population.

GM crops are believed to be more robust in nutritional value and taste, immune to adverse weather conditions such as droughts. These can be resistant to pests, and should reduce the use of herbicides and pesticides

Which of the following best describes how a blood cell and skin cell have the exact same DNA sequence and yet
Oliga [24]

Answer:

The proteins are expressed differently in each cell.

Explanation:

<u>The correct answer would be that the proteins are expressed differently in each cell. </u>

The regulation of gene expression is primarily responsible for differential functions of the same DNA sequence. Multiple proteins are formed from the same DNA sequence but only the required ones are specifically expressed depending on the cell.

<em>In other words, in the blood cells, the protein is expressed for performing blood-specific functions while it is expressed for performing skin-specific functions in the skin.</em>

Botulinum toxin is produced by Clostridium botulinum, a gram-negative bacterium. The toxin actually consists of 7 related toxins
Bess [88]

Answer:

A. Botulinum toxin possesses a heavy chain and a light chain, each of which takes part in the toxicity. The binding of the protein and its invasion within a nerve cell is permitted by the heavy chain. After the entry is permitted, the light chain functions like a protease and chops proteins, which would usually permit neurotransmitters to discharge out from the cell. This is basically a commotion of exocytosis or the discharging of neurotransmitters.  

The acetylcholine, that is, the obstructed neurotransmitter generally conducts a nerve impulse to a muscle, allowing the muscle to contract. By inhibiting the neurotransmitter, the botulinum toxin results in its distinctive flaccid paralysis.  

B. The small doses of the sterile, purified botulinum toxin when used in a medical setting as an injectable form prevent the release of a chemical known as acetylcholine by the nerve cells, which signal contraction of the muscles. By selectively interfering with the underlying tendency of the muscles to contract, the prevailing frown lines are smoothed out, and in the majority of the cases are almost invisible for a week.
