Answer:
The benefits and harms of learning about my DNA are mostly in medical, personal, civil and criminal fields.
Explanation:
a) Pros: learning about my genome sequence could provide new information on the genetic basis of poorly understood diseases with the potential to provide new therapies, immediate benefits based on the current understanding of genetic and health. Being aware of elevated risks for known diseases could allow me to make proactive decisions about my health such as visiting the doctor frequently for more check ups, screening. Choosing one type of prescription drug over another based on my metabolism, changing my diet or exercise plan, informing reproductive decisions, moreover, I would personalize my health care precisely.
b) Cons: the potential harms are the privacy invation, database exposure , which could lead to serious implications for the criminal justice system, which generally seeks to increase the availability of DNA samples from the population. It would create genetic discrimination, meaning that would be harder to find jobs, contract insurance, even though we have a Genetic Information Nondiscrimination Act.
The volume of oxygen gas that accumulates in the top of the tube is Moving the light source closer to the beaker. <u>Option A.</u>
<u />
The photo shows a student's experiment using Irodea a widespread aquatic plant. In this experiment, which is most likely to increase the amount of oxygen gas that collects at the top of the tube? Move the correct light source closer to the beaker.
Photosynthesis is the process that involves the chemical reaction between water and carbon dioxide in the presence of light to produce food for plants and release oxygen into the atmosphere as a by-product. The relationship between pressure and volume Boyle's Law. As the pressure of the gas increases the gas particles are pushed together thus reducing the volume of the gas.

Answer: Polyphyletic
Explanation: The kingdom Protista is considered Polyphyletic because their taxa do not share a common descendant that is many are developed by from many ancestral lineage. Protists are difficult to classify. They may be unicellular, colonial or multicellular. Polyphyletic groups mess up organizational systems.
As eukaryotes, protists can have many diverse organelles which includes a nucleus, mitochondria, contractile vacuoles, eyespots, plastids, pellicles, and flagella. The protists nuclei consist of chromosomes, with DNA linked with proteins. Protists can undergo sexual and asexual reproduction, meiosis, and mitosis. Protists can be free-living, or live symbiotically with another organism. This symbiosis can be mutual or parasitic. Many protists are economically beneficial to humans, while several others can cause fatal diseases. Protists make up the most of the planktons in aquatic life, where they areas the primary producer of the food chain. Many protists are motile using cilia, flagella, or pseudopodia (false feet) to move, while others are sessile( non-motile). They may be producing their own food from sunlight (autotrophs) or using a outside source of nutrition from outside (heterotrophs) . Researchers are currently comparing the RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) sequences of the protists with that of plants and animals, but no conclusive evidence has been reached. It is unknown to many researchers whether protists were the precursors to plants, animals or fungi or bacteria.
