Answer: The atom is mostly empty space.
Explanation:
Before to Rutherford, the accepted model for the atom was Thomson's model:
The atoms were a positive sphere, with electrons occupying space in it".
This was called the "plum pudding model".
Then came Ernest Rutherford, and he created a model where the atoms are mostly empty space (void) with a positive charged nucleus (really compressed in the center), and the electrons were orbiting around it.
Then the correct option is that the atom is mostly empty space.
Answer:
The atom is mostly empty space

Which of the following is true about ischemic stroke? a. Often caused by emboli from the basilar arteries b. Has risk factors that include atherosclerosis c. Can be a result of a hypercoagulable state d. Results from hemorrhage into brain tissue Is associated with acute hypertension
Answer: Option B.
Has risk factors that include atherosclerosis
Explanation:
Ishchemic stroke has a risk factor that include Atherosclerosis because it is when blood clot causes a blockage to artery that supplies blood to the brain.
This is major caused by buildup of plagues or deposition of cholesterol ( atherosclerosis). The blockage reduces the blood flow and oxygen to the brain, which cause damage or death of brain cells
If the arteries become too narrow, blood cells may collect and form blood clots.

Laboratory aprons are often required during lab activities. Your instructor will tell you whether it is mandatory or not. True False
Answer:
True
Explanation:
Before students can begin work in a laboratory, they would need proper orientation on the dos and don'ts in the laboratory. The orientation is important because the laboratory is a place where serious work is done and which houses chemicals that could be dangerous when not handled properly. The orientation is provided by an instructor who among other things explains to the students why an apron is important and should be worn at all times during laboratory activities.
The laboratory apron is important as it protects people in the laboratory against corrosive materials. It is also designed in a way that it can be easily pulled from the wearer when an accident occurs. After this orientation the students would not have to be reminded everyday by the instructor about the importance of laboratory aprons.
It is true that laboratory aprons are often required during lab activities. Your instructor will tell you whether it is mandatory or not.
When performing lab work, aprons are frequently needed to protect the wearer's clothing from possible spills, splashes, or chemical exposures.
The particular requirements for donning a lab apron, however, could differ based on the lab, institution, or type of experiment being carried out.
In order to determine whether or not a laboratory apron is required for a given lab activity, the instructor or lab supervisor is the reliable source.
To ensure safety and compliance with the unique procedures of the laboratory, it is crucial to adhere to the directions and guidelines given by the teacher.
Thus, the given statement is true.

2. the year the next magnetic reversal will take place
3. the location of ancient faults caused by seismic activity
4. the exact location of the next earthquake along the California coast
5. the direction plates are moving relative to each other
6. the speed of one plate as it subducts below another plate
Answer:
1. the cause of magnetic pole reversals
2. the year the next magnetic reversal will take place
4. the exact location of the next earthquake along the California coast
Explanation:
Due to magnetic striping patterns, the magnetic pole of earth go in reverse direction. When the magma comes out from the ocean floor so it spreads on the ocean floor making new bands. So these new bands that spreads the ocean floor make a new floor which change the polarity of the ocean floor in opposite direction. Due to this magnetic striping, the magnetic reversal will take place in which polarity of the earth crust reverses.
Answer:
The direction plates are moving relative to each other
The speed of one plate as it subducts below another plate
The location of ancient faults caused by seismic activity

Which is emergent property is not correctly matched with the level of organization: organism: personality ecosystem: nutrient cycling organ: reproduction of self population: social structure?
Answer:
organ: reproduction of self
Explanation:
Emergent properties are defined as the properties that arises when different system components working together and it do not represent property of an individual.
Self reproduction of an organ is not an emergent property because it is representing an individuals property and do not show any interaction with other level of organisation.
Hence, the correct answer is "organ: reproduction of self ".

Explanation:
The endomembrane system (endo- = “within”) is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins. It includes a variety of organelles, such as the nuclear envelope and lysosomes, which you may already know, and the endoplasmic reticulum and Golgi apparatus, which we will cover shortly.
Although it's not technically inside the cell, the plasma membrane is also part of the endomembrane system. As we'll see, the plasma membrane interacts with the other endomembrane organelles, and it's the site where secreted proteins (like the pancreatic enzymes in the intro) are exported. Important note: the endomembrane system does not include mitochondria, chloroplasts, or peroxisomes.
Let's take a closer look at the different parts of the endomembrane system and how they function in the shipping of proteins and lipids.

How might you explain the discrepancy between the normal length of prolactin (199 amino acids) and the length of the polypeptide synthesized in your experiment (227 amino acids)
The best way to explain the discrepancy between the normal length of prolactin (199 amino acids) and the length of the polypeptide synthesized in the experiment (227 amino acids) is that in the absence of Signal Recognition Particle (SRP) and the Endoplasmic Reticulum membrane,a prolactin precursor molecule is therefore synthesized.
Prolactin also plays a role in the stimulation of the proliferation of oligodendrocyte precursor cells.
Relating to all, The Signal Recognition Particle plays a crucial role in mediating the transport of secretory and membrane protein to the Endoplasmic Reticulum or plasma membrane.
This can occur both in the prokaryotic or eukaryotic cell.

HELP ME PLEASE! The global climate is changing, and this change is apparent across many of Earth’s subsystems. Multiple sources attribute the global warming of the past 50 years to human activity and influence. Activities such as deforestation and burning fossil fuels such as coal, oil, and natural gas release carbon dioxide (CO2), methane, and nitrous oxide into the atmosphere. These heat-trapping “greenhouse gases” have increased global temperatures and caused changes such as melting glaciers and powerful storms. These changes are happening because Earth's air, water, and land are all linked to its climate. How do you think greenhouse gas emissions and global climate will change during the next 50 years? If greenhouse gas emissions and global temperatures continue rising, what other changes might you expect to see throughout the world? Humans are working to reduce the amount of greenhouse gases released into the atmosphere, but are their current solutions going to make a big enough impact? In addition to reducing human dependence on fossil fuels, what other solutions could help combat greenhouse gas emissions and global warming?
Explanation:to control global warming we should control the green house gases which are the carbon dioxide formed by burning fossil fuels, methne formed by burning Agricultural fields, and also the nitrous oxide from nylon manufacturing.
So as a solution we should use technologies whichcan reduce smokes like by using solar and electric cars and recycling wastes instead of burning

As stated last unit, people are the ones at fault for destroying the earth, which was proven during the April 2020 quarantine. The earth was healing itself since it didn't have people to hurt it, which is sad when you think about it. I think we are on the right track with using more renewable energy sources, carpooling when possible, drive electric cars, etc. If nothing is done, then we could see possible extinction of species, due to the disruption of the food chain, melting of polar ice caps, etc.
But I believe that 50 years from now, the climate will be much worse than it is today. I think that global warming will reach a peak, most likely within the next century, and then start cooling down as people realize they need to start being more careful with their planet. I believe that because of the heat, the ice caps will start melting more and more, leading to the rising of sea levels and drastic flooding. People are trying to help save the planet, but it might not be enough. Solar power, electric cars, and making deforestation illegal all help, but we need to do more. We need to make solar power and electric cars more popular and wider spread. We also need to make growing back the destroyed forests a top priority. I believe that humans are trying, but we need to get more people on board to help.

There are usually more prey compared to the
predators that feed on them.
Which of the following statements explains this?
All of the energy stored in the prey is transferred up the
food chain
Predators need energy for cellular respiration but their
prey do not
Only some of the energy stored in the prey can be used
by the predators to stay alive
Answer:
Hi! The answer is Only some of the energy stored in the prey can be used by the predators to stay alive.
Explanation:
Predators are fewer in number than prey because they are higher up the food chain. In a food chain, an organism passes on only part of the energy it receives from food. With less energy, each level in a food chain supports fewer individuals than the one below it.

Please Help Me: Why would water have to be present on Earth before life?
Answer:
cells have processes that must be carried out like respiration etc that requires a transfer of material from cell to cell or within the cell therefore water is a medium for this transfer
Water would have to be present on earth before life because it is one of the main constituents of cells as well as its membrane.
What is the function of water in living cells?The function of water in living cells is that it acts as a solvent in order to assist cells in transport and utilize substances like oxygen or other significant nutrients.
It is necessary to have water before the imagination of life on the earth's surface. This is already mentioned that water is essential for all metabolic activities, cell transport, etc. Water is extremely filled in the cell's cytoplasm and delivers important cellular functions.
Apart from this, the majority of living beings need water to eliminate thirst as well as other physiological processes.
