The earth , the sun , and the seven other planets that are in orbit around the sun are part of the solar system. How does the size of the solar system compare with the size of the milky way galaxy ?
Answers
Answer:
Size of milky way galaxy is very large than our solar system.
Explanation:
The size of the solar system is much smaller than the size of the milky way galaxy because our solar system is a part of milky way galaxy. The radius of our solar system is 4.545 billion km while on the other hand, the radius of the milky way galaxy is 52,850 light years which is very very large than the radius of our solar system. Milky way galaxy has 100–400 billion planets while in our solar system has only eight planets.

when do birds use their teeth????
Answers
Answer:
to eat worms
Explanation:
Answer:
Birds do not have teeth, however...Explanation:
[tex]--------------------------------------------[/tex]
According to The Cornell Lab, "Birds do not have teeth, however, they may have ridges on their bills that help them grip food, but this does not count as teeth. So what about birds that have “tooth” in their name, like Double-toothed Kite? Some birds of prey have a sharp ridge or “tomial tooth” on the bill that they use to bite into their prey when subduing it. But these modifications to the bill surface are not considered the same thing as individualized teeth seen in other animals."

Considering ethical questions is part of a marine scientist’s job. Part of being ethical is doing your homework and exploring all sides of an issue. Choose a current ethical issue in marine science, such as the use of genetically modified organisms (GMOs), conditions in fish farms, or another topic your instructor approves. Find two perspectives supporting one side of the ethical issue and two supporting the other. Be sure to use reliable sources, such as university web sites or newspaper/magazine articles. Create an outline with at least five points for each side. Then write a brief paragraph explaining what you believe an ethical choice around this issue is. Remember, ethical problems are difficult because both sides have valid points. Be sure to consider and discuss at least one point you think is valid from the side that you disagree with in your conclusion as you explain why your choice is the ethical one. Also, include a list of sources that you used. Two is the minimum for each point of view.

One current ethical issue in marine science is the use of genetically modified organisms (GMOs) in aquaculture.
What are genetically modified organisms?Genetically modified organisms (GMOs) are living organisms whose genetic material has been artificially altered in a laboratory using genetic engineering techniques.Here are two perspectives supporting each side of the issue:
Perspective 1: According to a report by the World Health Organization (WHO), GMOs have the potential to reduce the environmental impact of aquaculture by decreasing the need for wild fish as feed, reducing the use of antibiotics, and decreasing the risk of disease outbreaks.
Perspective 2: Opponents of GMOs in aquaculture argue that they pose a significant risk to wild fish populations and the environment. According to the Ocean Conservancy, GMO fish can escape from fish farms and breed with wild fish, potentially altering the genetic makeup of natural populations and harming biodiversity.
Therefore, use of GMO's is profitable as well as hazardous for the environment.

please help this is due at 3pm
Answers
1: For example, rhinovirus has over 100 different serotypes. Now, the good news is that you can't get ill from the same virus serotype right after getting better, due to the fact that you'll have developed antibodies which help to protect your immune system for a little while.
2:Most children in the United States are now vaccinated against measles virus; before vaccination was widespread, most were naturally exposed to this virus and suffered from an acute, unpleasant, and potentially dangerous viral illness. Whether through vaccination or infection, children exposed to the virus acquire long-term protection from measles. The same is true of many other acute infectious diseases: this state of protection is a consequence of immunological memory.
The basis of immunological memory has been hard to explore experimentally. Although the phenomenon was first recorded by the ancient Greeks and has been exploited routinely in vaccination programs for over 200 years, it is just now becoming clear that memory reflects a persistent population of specialized memory cells that is independent of the continued persistence of the original antigen that induced them. This mechanism of maintaining memory is consistent with the finding that only individuals who were themselves previously exposed to a given infectious agent are immune, and that memory is not dependent on repeated exposure to infection as a result of contacts with other infected individuals. This was established by observations made on remote island populations, where a virus such as measles can cause an epidemic, infecting all people living on the island at that time, after which the virus disappears for many years. On reintroduction from outside the island, the virus does not affect the original population but causes disease in those people born since the first epidemic. This means that immunological memory need not be maintained by repeated exposure to infectious virus
Osmosis requires energy
True

False
Answers
Answer:
Diffusion and osmosis don't require the cell to expend any of its own energy, as they are passive processes. As we know both are passive processes and yet (in basic, short terms) diffusion is higher to lower and osmosis is lower to higher, so movement to concentration doesn't determine whether it is active or passive.

Scientists discover two planets orbiting a distant star. The average distance from the star to Planet A is 4 AU, and it takes 432 Earth days for Planet A to orbit the star. If it takes 1,460 days for Planet B to complete an orbit, what is the average distance from Planet B to the star?
Answers
Answer:
3.3
Explanation:
no reason for the explanation
Answer:
C. 9 AU
Explanation:
The period (T) of Planet A is 432365=1.2 Earth years. The period of Planet B is 1,458365=4.0 Earth years. Kepler's Third Law states that
a3=kT2
Substituting the known values of a and T for Planet A, we have
43=k⋅1.22
64=k⋅1.4
k=45.7
Using this value for k, we can solve for the distance from Planet B to the star
a3=45.7⋅4.02
a3=731.2
a=9.0AU
An alternative solution is to notice that a3T2=k for both orbits, which means that the ratio a3T2 is the same for both orbits. So, 434322=x314582. Solving this proportion gives x3=729, so x=9.0AU.

Which mechanism explains how both A and B antigens produce type AB blood?
Answers
Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
Hence, The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.

Creativity in narrative essays oftentimes manifests itself in the form of authorial perspective. narrative essays are effective when the language is carefully, particularly, and artfully chosen. Use specific language to evoke specific emotions and senses in the reader. the use of the first person pronoun ‘I’ is welcomed; though it is welcomed it is not necessary—nor should it be overused for lack of clearer diction.have a clear introduction that sets the tone for the remainder of the essay. Do not leave the reader guessing about the purpose of your narrative; you are in control of the essay, so guide it where you desire (just make sure your audience can follow your lead).I hope that this helps you!
