Answer: This is an opinion question so I will give you the facts so you can form your own opinion for this answer.

Explanation:

<u>PRO GMO:</u>

Manufacturers use genetic modification to give foods desirable traits. For example, they have designed two new varieties of apple that turn less brown when cut or bruised.

The reasoning usually involves making crops more resistant to diseases as they grow. Manufacturers also engineer produce to be more nutritious or tolerant of herbicides.

Crop protection is the main rationale behind this type of genetic modification. Plants that are more resistant to diseases spread by insects or viruses result in higher yields for farmers and a more attractive product.

Genetically modification can also increase nutritional value or enhance flavor.

All of these factors contribute to lower costs for the consumer. They can also ensure that more people have access to quality food.

<u>CONS of GMO</u>

Because genetically engineering foods is a relatively new practice, little is known about the long-term effects and safety.

There are many purported downsides, but the evidence varies, and the main health issues associated with GMO foods are hotly debated. Research is ongoing.

Some of the cons include: Allergies, Cancer, antibacterial resistance, and outcrossing which refers to the risk of genes from certain GMO plants mixing with those of conventional crops.

Which statements are true regarding pharmacodynamics and the pediatric client? select all that apply?
prisoha [69]
The statements that are true are the following:
1. The levels of microsomal enzymes are decreased.
Microsomal enzymes are functional parts of the human liver, which participate actively in the drug metabolism. It has been shown that the activity of these enzymes is lower in children, reaching its full activity in adult individuals. 
2. First pass elimination is reduced because of the immaturity of the liver.
First pass elimination is a phenomenon of drug metabolism, that occurs in the liver or the gut and involves the reduction of the drug concentration before it reaches the systemic circulation. In neonates, the liver is immature and undergoes several changes during the postnatal period.
3. Gastric emptying is slowed because of slow or irregular peristalsis.
 Peristalsis is a term referring to the movement of food to several positions of the digestive tract, through muscle contractions. Gastric emptying is strongly affected by peristalsis. Some children have irregular peristaltic movement.

Select all that apply. Choose the cells that are diploid. egg nerve bone sperm muscle
Natali5045456 [20]
The diploid cells in this case include nerve cell, bone cell and muscle cell. A diploid cell is a cell that contains two sets of chromosomes, which is double the haploid chromosome number. They include all the somatic cells with exception of germ line cells. Gametes are haploid cells meaning they only have one set of chromosomes. During sexual reproduction, gametes (sperm and egg cells) fuse at fertilization to form a diploid zygote which develops into a diploid organism.
