Answer:
True
Explanation:
Light behaves in specific ways. It can be reflected, refracted, or absorbed, and under certain conditions, run into different kinds of interference. Which explanation best describes why light is refracted as it enters water?
A. The light bends when it enters water due to its reflection.
B. The speed of light remains the same as it moves from air to water, causing the light to reflect.
C. The speed of light increases when it enters a different medium, but it doesn't bend.
D. The speed of light changes as it moves from air to water, causing the light to bend.
Answer:
D
Explanation:
Refraction is generally defined as the change in the direction of a wave as it travels from one medium to another. Light is a form of wave and light refraction is caused by a change in the speed of light as it moves from air to water, causing the light to bend in the process. The medium of travelling has to be transparent.
The change in the speed and direction is due to the variability in the refractive index of media. Light travels faster as it moves from a medium of higher refractive index to a medium of lower refractive index and vice versa.
The correct option is D.

Answer:
The viral proteins will be radioactive.
Explanation: Bacteria are microorganisms that have been found to be the cause of many diseases of living organisms.
T2 phage is usually called enterobacterio phage T2 which has been known to be very virulent and infectious to a bacteria like E-coli when done in the presence of sulfur it usually leads to the formation of radioactive viral proteins due to the impact of radiation.

How do scientists say the melting ice can contribute to disease occurrence? Also example
Answer:
In the melting of icebergs, icebergs could potentially contain long-dormant bacteria and viruses. Those viruses trapped in ice and permafrost for centuries, can be reactivated. That means melting those ice could potentially open a Pandora's box of diseases. Including some that have caused global epidemics in the distant past.
Example: babesiosis
As of regular ice. The freezing of bacteria in water isn't just an old practice and ice from unclean sources could also contain disease, when melted and ingested or touched this ice as well could transmit disease not so long-dormant, however still unpleasant.
Example: AIDS

The decline in approximately 70% of the world’s bird species is particularly alarming to scientists because ____ .
Answer:
See the answer below
Explanation:
The approximately 70% decline in the world's bird species is alarming to scientists because some species of birds have been found to be good indicators of the health status of the environment. Birds are generally easy to detect in an environment and the ability to fly away due to terrible conditions of habitat makes them a good indicator of the health of habitats or environment in general.
A 70% reduction in the species of birds worldwide is thus alarming due to the direct correlation that exists between the species diversity of birds and the health of the environment. It could presumably be an indication that about 70% of the world's habitat has been destroyed or impacted negatively.

Answer:The only difference between a molecule of a compound and a molecule of an element is that in a molecule of an element, all the atoms are the same. For example, in a molecule of water (a compound), there is one oxygen atom and two hydrogen atoms. But in a molecule of oxygen (an element), both of the atoms are oxygen.

1. How does a clock and its internal and intricate mechanical parts make up a system(Explain)
2. Is it a living or nonliving system? (Explain)
3. How may it support a living system? (Explain)
4. Therefore what is an good example of a definition of a system?
Answer:
1. A clock with internal mechanical parts comprises a system because it is a combination of various parts that a heterogeneous in nature and function working together to achieve one end - indicating the time accurately.
Some mechanical clocks comprise of at least 10 parts namely:
Gear train: This component alone is a sub-system that comprises of at least 8 parts. These parts are broadly classified into wheels, pinions, and barrels.Main SpringPalletEscapement Escapement WheelBarrell Barrell WheelBalance Spring etc2. A clock is a non-living system.
Living systems have certain characteristics. Some of them are:
Stimuli: Response to the environmentGrowth and development: The are able to increase in size and dimensionsHomeostasis: this is the capability of self-regulation regardless of external conditions such as temperature and pressure. etc3. A cannot support a living system. It can however help a human being (which is essentially a combination of various systems) to tell the time.
4. a system is a combination of heterogeneous parts that work in unison to form a whole complex entity that can perform one or more functions.

Different cell types can react differently to epinephrine in the human body. Choose two cell types in the human body and briefly describe the cellular effect that occurs in the presence of epinephrine.
Answer:
I haven't really learned about cell types but I did find this information
Explanation:
How can epinephrine have different effects on different cells? Different cells have different receptors that bind epinephrine. Different cells activate different enzymes as a result of epinephrine binding.
epinephrine induces increased vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction. Other significant effects include increased heart rate, myocardial contractility, and renin release

What role does iodine play within the thyroid?
three sentences about the role termites play in modifying the natural proses of water carbon or nitrogen cycle
Answer:
-help to store water in the soil (by increasing infiltration) rather than evaporating (enabling the plants survive long periods of drought)
-mix inorganic and organic compounds in the soil (and thus it can better resist the process of erosion)
-termite’s feces help to prevent erosion
Explanation:
Decomposers break down complex organic matter into basic compounds containing nitrogen, phosphorus, and calcium, generating water (H2O) and carbon dioxide (CO2) during this process. Termites are critical in an ecosystem because they are decomposers, i.e., they are recyclers that break down organic material into nutrient-rich soil. For example, termites digest the cellulose from dead plants (due to the presence of specific bacteria in their digestive tract), thus allowing the carbon cycle.
An aquarium with a glass lid is an example of an isolated system.
true
false
Answer:
The answer is false!
Explanation:
I took the K12 science quiz. I hope this helps! Have a blessed day! :)
The statement "An aquarium with a glass lid is an example of an isolated system" is false as light, air, and heat can transfer through the glass lid.
What is an aquarium?An aquarium is an artificial place that is made for putting fish and other water animals in houses buildings and other places. Aquariums are made up of glass so can we, so we can see the fish's aquarium also have oxygen pumps the water also changed in the aquarium from time to time and. The aquarium is kind of decorative.
Aquariums are made up of glass, and they are open from the top so that fish can get air.
An aquarium is not an isolated system as light year and heat can transfer through the top and fishes are living organisms that need an open system to breathe and live.
Therefore, the statement is false.
