Answer:
1. the DNA of which has been modified using genetic engineering methods. In most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species.
2. GM crops are made through a process known as genetic engineering. Genes of commercial interest are transferred from one organism to another. Two primary methods currently exist for introducing transgenes into plant genomes. The first involves a device called a 'gene gun'.
3. Crops do not damage the environment simply because they are GM. Some farming practices, such as the overuse of herbicides resulting in the excessive eradication of wild plants from farmland have been shown to harm the environment. These problems are similar for non-GM and GM crops.
Answer:
Because natural selection selects for it. Thus it persists.
Explanation:
You have to understand heterozygote advantage. Basically, it's where heterozygotes have an advantage over homozygotes. In the case of sickle cell disease, heterozygotes have an advantage, and natural selection favors whatever is advantageous. Thus, because heterozygotes each have one recessive sickle-cell allele, as natural selection favors the heterozygotes, the recessive sickle-cell allele persists and remains in the gene pool.
Answer:
Life processes are the series of actions that are essential to determine if an animal is alive. 2. What are the Life Processes? There are seven essential processes in common: movement, respiration, sensitivity, growth, reproduction, excretion and nutrition or MRS GREN.

People with central sleep apnea experience a complete cessation of respiratory activity for brief periods of time yet do not have frequent awakenings and do not tend to feel tired during the day.
<h3>What is sleep apnea?</h3>
Breathing regularly stops and starts during sleep, which is known as sleep apnea. People may have sleep apnea if they snore loudly and still feel exhausted after a full night's sleep.
These are the primary forms of sleep apnea:
The more prevalent type of obstructive sleep apnea happens when throat muscles relax.
Central sleep apnea, which develops when your brain fails to properly activate the breathing muscles,
When a person has both central and obstructive sleep apnea, it is known as complex sleep apnea syndrome, also called treatment-emergent sleep apnea.
