Answer: PCR allows us to target and amplify one specific segment of DNA that is a few hundred base pairs in length out a complete genome of over 3 billion base pairs.

"Bingeing but not purging" is associated with binge-eating disorder.
Explanation:
Binge eating disorder (BED) is a severe, life-threatening, and curable ingestion illness categorized by recurring incidents of intake big amounts of nutrition (often very quickly and to the point of discomfort); a sensation of a loss of control throughout the binge; feeling disgrace, suffering or guilt later; and not frequently using unhealthy compensatory trials (e.g., purging) to pledge the binge eating. It is the most common eating disorder in the United States.
Answer:
Vascular plants have separate tubular tissues such as xylem, phloem for smooth transport of water, minerals and food while non-vascular plants do not show these attributes.
Explanation:
Although both life cycles are divided between the sporophytic and gametophytic generations, vascular plants have a dominant diploid sporophytic phase while non-vascular plants have a dominant haploid gametophytic phase.
Non-vascular plants are poikilohydric (they can withstand dehydration and can recover without any damage to their tissues), though they cannot control the water level in their cells and tissues. On the other hand, vascular plants are homoiohydry. They can survive in any habitat and can control the water content in cells and tissues, though they have low capacity to survive dessication compared to the non-vascular plants.
Non-vascular plants do not have true leaf. The leaves are mere chlorophyll containing. Photosynthesized food are directly sent from one cell to the other. They lack proper transport mechanism for food and water.
On the other hand, the vascular plants have complex multilayered leaf (cells) structure. The waxy layer cuticles on the leaves prevent dessication. That are more chlorophyll containing than their counterpart.
The correction is B.
The respiratory system is the one that is responsible for transportation of oxygen from the outside to the lungs and the reverse transportation of carbon dioxide from the body to the atmosphere. The muscular system is responsible for the contraction of muscles around the air passages during respiration. These two systems are negatively affected in asthma patients during respiration.
Answer:Environmental science is the pursuit of knowledge about the workings of the environment and our interactions with it. Environmentalism is a social movement dedicated to protecting the natural world. Nature makes resources at similar speeds.
