In some cases, people who test positive for genetic testing can receive
preventive treatments. For example, people who test positive for the breast
cancer genes BRCA1 and BRCA2 can have a preventive mastectomy (breast
removal surgery) before they develop the disease. In other cases, no preventive
treatments are available, but frequent monitoring can help detect a disease
earlier, when it's more easily treated.
What ethical or professional concerns does a health-care professional need to
address when he or she has a patient who wants to prematurely treat a genetic
disease? Do you think genetic testing should be part of normal preventive
healthcare? Why or why not?
Answer:
Discrimination occurs due to presence of "inferior" genes
Explanation:
Discrimination occurs due to presence of "inferior" genes is the ethical or professional concerns that the health-care professional need to address when he or she has a patient who wants to prematurely treat a genetic disease. Yes, I think that genetic testing should be a part of normal preventive healthcare because this genetic testing provides information about inheritable diseases. This testing can avoid future diseases by treating it before it causes severe damage to the body.

Why do we classify lionfish populations near the eastern United States as an invasive species? What suggests that these new populations are not an expansion of the lionfish’s natural range? View Available Hint(s) Why do we classify lionfish populations near the eastern United States as an invasive species? What suggests that these new populations are not an expansion of the lionfish’s natural range? Lionfish are native to the tropical Pacific. There are no natural water routes of warm water between the Pacific and Atlantic oceans.
Answer:
Lionfish is introduced in this region.
Explanation:
The lionfish populations near the eastern United States is considered as an invasive species because this fish is not native species of this region and they were introduced into this region. Due to no predator available for this lionfish will make it invasive species that eliminated the local fish species and disturb the ecosystem. Lionfish are native to the tropical Pacific and there are no natural water routes of warm water between the Pacific and Atlantic oceans which helps this lionfish to reach eastern United States so we can say that it was introduced by humans.
How does the presence of cosmic microwave background radiation support the big bang theory?
Check all that are true.
-It shows that here is a faint, leftover energy that is coming from all directions of the universe.
-It shows that the universe used to be smaller with a uniform temperature.
-It shows that the universe is coming back together and will collapse in a massive black hole.
-It shows that all matter and energy in the universe is accelerating.
Answer:
I'm pretty sure that it's B
It shows that the universe used to be smaller with a uniform temperature. Therefore, option (B) is correct.
What is cosmic microwave background radiation?According to the theory of the Big Bang, the cosmic microwave background is an electromagnetic radiation that is a relic from an earlier stage in the development of the universe. This radiation is also known as "relic radiation." The Cosmic Microwave Background (CMB) is the weak radiation that permeates all of space.
One of the primary confirmations of the Big Bang is thought to be its discovery and thorough studies of its attributes. The cosmic background radiation was accidentally discovered in 1965, which shows that the early cosmos was dominated by a radiation field with extraordinarily high temperatures and pressure.

Creepers and climbers have thin, slender stems and cannot stand upright on their own.
Climbers, such as jasmine, grapevine, and money plant, require external support to grow vertically. Creepers, such as watermelon and pumpkin, grow horizontally on the ground.
A grapevine, also known as a grape, is a stem-tendril climber plant with cascading growth that grows in an upward direction.
Every year, new shoots emerge from this plant. It is grown to a height of 19 meters or more, depending on the pruning technique used.

How is antibiotic resistance related to Natural selection?
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.
Explanation:
If a cow only had the dominant phenotypes what traits would be shown
Answer- Some examples of traits that are simply inherited with complete dominance are red/black coat color, horned/polled and lethal defects.

A. producers do not need energy
b. energy is never recycled
c. nutrients are never recycled
Answer:
B. Energy is never recycled.
Explanation:
Chemical nutrients and energy tend to flow in the same direction for most of an ecosystem. The big difference is that the chemical nutrients are recycled in the ecosystem while the energy is lost from the ecosystem to the universe at large. Energy in any ecosystem comes from the Sun.

Which description best contrasts the roles of the small and large intestines?
The small intestine breaks down compounds, while the large intestine absorbs water
The small intestine stores food waste, while the large intestine removes food waste.
The small intestine takes In nutrients, while the large intestine eliminates waste.
The small intestine excretes Juices to digest food, while the large intestine absorbs nutrients.
Answer:
The small intestine takes in nutrients, while the large intestine eliminate waste.
Explanation:
Small intestine doea not break down compounds, it is stomach's job. It is good at absorbing nutrients. Large intestine does not usually absorb nutrient, it absorbs water and eliminate waste. So combine all of this, the best answer is the third one.❤️

the maria have few craters compared to the surrounding areas because ______
Answer:
Due to absence of erosive agents.
Explanation:
The Maria have few craters compared to the surrounding areas because of no erosive agents such as winds and rain. The erosive agents only formed when there is atmosphere in the region. The atmosphere is responsible for the presence of winds and rainfall. If these erosive agents are present, there will be more craters as compared to the region where no erosive agents are present so that's why Maria have few craters in the region. as compared to the surrounding region.
How did the research of Miller and Urey contribute to the hypotheses about the origins of life on Earth?
Answer:
Miller and Urey's research showed that it was possible for organic molecules to be developed from inorganic molecules, which contributed to the hypotheses about the origin of the earth.
Explanation:
Stanley L. Miller and Harold C. Urey developed a series of research and experiments that showed that the planet earth, even in its primitive state, promoted a series of chemical reactions that used inorganic substances as a reagent, to create organic substances as a product and these organic compounds were the precursors of life on earth.
To reach this conclusion, they used a closed system, without the presence of oxygen, but with the presence of hydrogen, ammonia, methane and water vapor. They subjected this system to various cycles of electrical discharges, heating and condensation of the page, to create environments in which chemical reactions could happen. After some time, it was possible to observe the presence of organic molecules.
