If the sun is so massive, why does the Earth have a greater pull on the moon than
the sun does?
Answer:
Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun
Viscosity is a measure of a fluid's resistance to
flow
A: True
B: False
Answer:
Viscosity is a measure of a fluid's resistence to flow is true i believe
Viscosity is a measure of fluids' resistance to flow a correct statement. So the correct option is True.
What is viscosity?The measurement of a fluid's resistance to its own flow and any objects that may be inserted in it is called viscosity.
Viscosity is given by the symbol η (eta) and is defined as the ratio of shearing stress (F/A) and the velocity gradient of the flow of a liquid (dvx/ dy).
Velocity is also defined in the form of Newton’s equation which states that the shear force resulting is directly proportional to the applied force and it is inversely proportional to the viscosity.
The SI unit for velocity is Pascal. Second (Pa S).
The other form of viscosity is called kinetic viscosity which is the ratio of a fluid’s viscosity to its density. It is given by ν (nu). It is a measure of the resistance of a liquid against flowing when it is under the influence of gravity. The SI unit of kinetic viscosity is a square meter per second.
Therefore, the above statement is true.

Which part of the environment incorporates carbon into the carbon cycle via water? (1 point)
O geosphere
o hydrosphere
O biosphere
O atmosphere
The part of the environment that incorporates carbon into the carbon cycle via water is the hydrosphere, which is present in the second option as in the hydrosphere water bodies are present, such as the ocean, etc.
What is the significance of the hydrosphere?On the earth, there are geospheres where the mountains and hills are present, and there are hydrosphere where the water bodies are present, and this hydrosphere is important because it is important for maintaining the carbon cycle. Carbon dioxide is exchanged between the atmosphere and the hydrosphere through processes such as photosynthesis and respiration that are carried out by plants and animals and these carbons is dissolved in water bodies.
Hence, part of the environment that incorporates carbon into the carbon cycle via water is the hydrosphere, which is present in the second option as in the hydrosphere water bodies are present, such as the ocean, etc.

Identify the plant cell organelle in which photosynthesis takes place.
Help pleaseeee!
Answer:
chloroplast
Explanation:
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
The plant cell organelle in which photosynthesis takes place is chloroplast. The correct option is D.
Plant cells and some algae contain unique organelles called chloroplasts. They have a green pigment called chlorophyll, which is in charge of absorbing solar light energy.
Chloroplasts utilize this light energy during photosynthesis to create glucose, a molecular energy source, and oxygen from carbon dioxide and water.
Because it enables them to transform light energy into chemical energy, which feeds their development and supplies them with nutrients, plants need this process to survive.
Because of their special adaptation for photosynthesis, chloroplasts are essential to the plant's capacity to produce food.
Thus, the correct option is D.

When Muhammed Ali beat Sonny Liston in 1965 to become heavyweight boxing champion of the world
Answer:
The correct answer is - option C. 2 billion.
Explanation:
Cyanobacteria or BGA are microscopic organisms that live in water bodies normally and make their own food. These are unicellular organisms that have been around 3 and a half million years and consider as the first photosynthetic organisms responsible for the availability of oxygen on earth. These cells are also considered as the cell that evolved in the eukaryotic cells by differentiation around 2 billion years ago. The aggregated form of the cells are known as the mats.

Answer:
They are renewable natural resources. They move round and round in cycles and never run out. When an animal like this cow eats a plant, it takes in nutrients. The nutrients are used in the animal's body and then many come out as waste, which returns the nutrients to the soil.

What do eukaryotic cells have that prokaryotic cells do not?

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.
Explanation:
An earthquake occurred three hundred miles off the shoreline, and massive flooding occurred on land as a result.
Which best describes what occurred?
- Continental shifting resulted in a tsunami.
- Continental shifting resulted in a volcano erupting.
- Tidal activity in the subduction zone caused a tsunami.
- Tidal activity in the subduction zone caused a volcano to erupt.
Answer:
An earthquake occurred three hundred miles off the shoreline, and massive flooding occurred on land as a result. Which best describes what occurred? Continental shifting resulted in a tsunami.
Explanation:
The best thing that describes the scenario that occurred is tidal activity in the subduction zone caused a tsunami. The correct option is C.
What is tsunami?The violent breaking of rock during an earthquake releases energy that travels through the earth in the form of resonance known as seismic waves.
These seismic waves radiate from the hypocenter in all directions, becoming weaker as they travel further away from the hypocenter.
Tsunamis are a series of large waves with extremely long wavelengths and periods that are usually caused by a violent, impulsive undersea disturbance or activity near the coast or in the ocean.
When a large earthquake ruptures, the faulting can cause vertical slip large enough to disturb the overlying ocean, causing a tsunami to travel in all directions.
Thus, the correct option is C.

DNA evidence analysis is an imperfect science. Provide two reasons why this may be the case.
For my Biomedical Science Class
Answer:
Not all DNA that was found at the scene has to be related to the scene.
Explanation:
Just because DNA was found at the scene, that doesn't mean that the person there is actually guilty. For example, in a case where person B is guilty, a strand of hair from Person A could be carried over to another scene on Persons B's clothing.
Answer:
Because DNA is more reliable than other forensics, scientists have shrugged off suggestions that it could fall victim to the vagaries of bias. But Dror noted that much DNA analysis involves interpretation. With interpretation comes subjectivity, and with subjectivity can come error. Only one-tenth of 1 percent of human DNA differs from one individual to the next and, although estimates vary, studies suggest that forensic DNA analysis is roughly 95 percent accurate.

Corals grow in dense groups on the floor of the ocean. Which type of distribution pattern does this represent, and what is the advantage of this distriubtion?
Answer:
Clumped distribution
Explanation:
Clumped distribution is a type of distribution in which organisms are clustered in groups. This is the most common form of distribution. Clumped distribution occurs in environment that are patchy (the patches are the part suitable for the organism to live in).
Clumped distribution is good because organisms have better protection from predators providing defense, and there is more access to food resources.
Since the Corals grow in groups on the ocean floor, hence it is a form of Clumped dispersions.
