What backs up a scientific law?
Answer:
Scientific laws are similar to mathematical postulates. They don't really need any complex external proofs; they are accepted at face value based upon the fact that they have always been observed to be true. Specifically, scientific laws must be simple, true, universal, and absolute.
Explanation:
Of the three waves shown, Wave 2 has the greatest
wave speed, because it has more crests than the other ropes
O frequency because it has a large wavelength than the other ropes
wave speed because the rope is moving up and down faster than the other ropes
frequency, because there are more crests in the same length of rope than there are in the other waves
Answer:
D. frequency, because there are more crests in the same length of rope than there are in the other waves
Explanation:
Wave frequency is defined as the number of waves passing a fixed point at a given time.
Wave frequency is highly influenced by the number of crests in the wave that pass the fixed point in 1 second. It means, more is the number of crests in the same length of rope, the higher will be the wave frequency.
Wave 2 has a maximum number of crests and thus wave 2 has the greatest wave frequency in comparison to other ropes.
Hence, the correct answer is "D".
What would happen if the mitochondria were missing from a cell?
Answer:
We'd be in big trouble...
Explanation:
The mitochondria is the powerhouse of the cell, without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration.
The absence of mitochondria would have a profound effect on cellular function, including the cell's ability to produce energy, regulate ROS levels, and control important signaling and metabolic pathways. Such a cell would likely be unable to survive for very long.
What is the effect of mitochondrial removal?Without mitochondria, the cell would not be able to generate ATP through aerobic respiration, which takes place in the mitochondria. Instead, the cell would have to rely on other, less efficient metabolic pathways to produce energy. Mitochondria are also important for regulating the levels of reactive oxygen species (ROS) in the cell. Without mitochondria, the levels of ROS would likely increase, leading to oxidative damage to the cell's proteins, lipids, and DNA. Mitochondria play important roles in cell signaling pathways, including those involved in apoptosis (programmed cell death) and calcium signaling. Without mitochondria, these pathways would likely be altered, which could have profound effects on cellular function and survival.
Hence, such a cell would likely be unable to survive for very long.

Earth is 150 million kilometers from the sun, and the solar "wind" travels at about 400 km/sec. How long does it take particles from a solar storm to reach Earth? (Hint: Time = Distance / Speed. To convert from seconds to hours, divide the time in seconds by 3600.)
Answer:
The correct answer is - 4.34 days.
Explanation:
Given:
Distance from the sun to earth = 150 million kilometer
= 1500,00,000 km
The solar "wind" travels = 400 km/sec
= 400*60*60 km/ hour
= 1440000 km/hour
Then time = distance/speed
time = 1500,00,000 km/1440000 km/hour
time = 104.166666667 hours
time = 104.166666667/24
= 4.34 days.

A microorganism that can replicate inside a host cell and able to disrupt the homeostasis and leads to the killing or death of the cell. A virus can be either a fast-acting or slow-acting virus.
Meningitis is one of the fast-acting virus so fast that can result in the death of the person within 24 hours if not get proper medical assistance. Whereas retroviruses, a group of viruses that is slow-acting and grouped on the basis of their structure and replication method, the major disease that is caused by these viruses is AIDS by a retrovirus called HIV.

Suppose we completely stopped burning fossil fuels immediately. How many years would it take to return to atmospheric CO2 levels from the year 1800, about 600 GtC? Use the Gizmo to find the answer.
Answer:
Explanation:
It would take 50 years to return to atmospheric CO2 levels from the year 1800. I know this because I set the fossil fuel usage to 0 and proceeded to simulate 50 years and that’s when the atmospheric CO2 levels returned to 600 GtC.
As per observation It could take 50 years to go back to atmospheric CO2 degrees from the yr 1800.
Each year, there has been no extrade in the quantity of CO2 withinside the ecosystem because of soil and land plants. coal also can be the answer.
What is co2 quantity ?Since 2000, the worldwide atmospheric carbon dioxide quantity has grown with the aid of using 43.5ppm, an growth of 12 percent. The contemporary-day document of atmospheric carbon dioxide degrees commenced with observations recorded at Mauna Loa Observatory in Hawaii.

base on what you have learned from the previous activities, define speech context in your own words.
plsss help
Answer:
This refers to the condition, environment and or circumstance under which a speech or communication was made.
Explanation:
The context of a speech can significantly alter their meaning even though the body of the information has not changed. This is why understanding contexts are very crucial.
The context of a speech helps the receiver to make a decision about what to place importance on and about what, he or she can safely make assumptions about.
Some examples of communication contexts are:
Mass communicationIntrapersonal communicationInterpersonal communicationGroup communicationPublic communicationCheers
Speech context has to do with the circumstances that are available which affects the meaning of a speech.
There are three types of speech context which include:
Intrapersonal InterpersonalPublicAs a result of this, when a person is making a speech to either himself, one more person, or to a group of people, it is important to note that the audience is very important so that the message will be well received.
Interpersonal communication has to do with the communication between people you have a close relationship with.
Intrapersonal communication is the type of communication where a person talks to himself, usually loudly.
Public communication is the communication among a group of people.

Large, circular lily pads are able to float on the water's surface.
Answer:
true
Explanation:
they're buoyancy
The property of water in "Large, circular lily pads are able to float on the water's surface" is cohesion.
What is cohesion?Cohesion refers to the attraction of one water to another. This force will cause the water in the lake to develop surface tension. The large and thin leaf of the water lily gives it a low force per area.
The leaf will float above the water if the force acting on the surface is not greater than surface tension. The ability of water spiders to walk on the surface tension of the water.
The leaves of lotus float on the water because the bottom of the leaves have edges and thick ribs that capture air between them, which helps them to float on the water.
Thus, the property of water that is shown in the given statement is cohesion.

what determines how far south the cold air from the north pole travels
Answer:
Please mark as Brainliest.
Explanation:
Polar easterlies are the cold and dry wind that blows from the polar regions (North pole and South pole) to the region of 60 degrees latitude. This type of wind is formed due to the sinking of the cold air resulting in the formation of a high pressure zone at both the poles. This wind when blows from the poles to the 60 degrees latitude, it slightly gets deviated towards the western side because of the effect of the Coriolis force. This Coriolis force comes into the picture due to the earth's continuous rotation.
Thus, the polar easterlies determines how far south the cold air travels from the North Pole.
Why are the tais pointing inward in layer H
Answer:
Because they are hydrophobic
Explanation:
The image shows a cell membrane, which is made up a phospholipid bilayer. The phospholipid bilayer is made up of a phosphate head, which is hydrophillic, and fatty acid tail, which is hydrophobic. That means they are repelled by water.
Because the tails are hydrophobic, they are repelled by the water towards one another, while the heads remain facing outwards,
