Make a list of the potential benefits and harms that might arise from knowing your complete genome sequence.
MaRussiya [10]

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.

Cells will usually divide if they receive the proper signal at a checkpoint in which phase of the cell cycle? see concept 12.3 (
miskamm [114]
Cells will usually divide if they receive the proper signal at a checkpoint in the G1 phase of the cell cycle. In mammalian cells , this checkpoint is called the restriction point. The G1 phase is a phase of the cell cycle that takes place in eukaryotic cell division. In this phase the cell synthesizes mRNA and proteins in preparation for the subsequent steps leading to mitosis. It ends when the cell moves into the S phase of interphase.

Question 23 (6 points)
Stels [109]

Answer: 1. Sea urchins and sea otters

2. They are prey for carnivores.

3. Sea otters, star fish

Explanation:

Sea urchins and sea otters are carnivores as they eat on the flesh of starfish and sea urchins respectively.

Starfish feed on the kelp forests which are the producers in the food chain and the starfish is the primary consumer and prey for sea urchins.  So, starfish and kelp forests are the prey in the marine ecosystem.

Keystone species is the one which controls the population of other inferior species in an ecosystem. Here, sea otters consume sea urchins so the population of sea urchins remained in control Starfish controls the population of kelp forest.

The digestive system and the excretory system both excrete waste. Which best describes how waste is secreted in each system?
miss Akunina [59]
I'm not 100% sure, but I think that the digestive system excretes solid wastes only and the excretory system excretes liquid wastes only. So the 3rd option is probably correct.
