Answer:
Explanation:
Genetics play a key part in understanding evolution. While two organisms may bear similar or no resemblance whatsoever to each other, their genes can tell us whether or not they were related- and creatures that show change (especially dramatic change) show us evolution through genetics.
Dylan wants to observe some onion cells with a microscope. He places the cells on a slide. Describe how Dylan uses the microscope so he can see the cells with a ×20 objective lens.
Answer:
See the answer below
Explanation:
After routinely cleaning the microscope and ensuring that all the parts are working fine, Dylan would have to place the slide on the stage of the microscope, switch on the light source, and adjust the diaphragm of the condenser to ensure that adequate light gets to the slide on the stage.
Thereafter, Dylan would need to turn the revolving nosepiece in order to shift to the lowest objective of the microscope assuming it is not already in place. Then, the slide on the stage is brought into focus (by viewing through the eyepiece/ocular) by using the coarse/fine adjustment knob to bring the stage up/down.
Once the slide is brought into clear focus, the revolving nosepiece is then turned to switch the x20 objective. Generally, at higher objectives, the coarse adjustment knob is rarely needed and the fine adjustment knob is solely used instead to bring the slide back into focus. Thus, Dylan can see the cells of the onion at the desired objective.

Answer: im just doing challenges
Explanation:
Source: "trust me"
Static frictional force is the minimum force that must be overcome for one object to slide over another.
What is frictional force?Frictional force is the force the acts between the surfaces of two objects in contact which oppose the motion of one object over the other.
The minimum force that must be overcome for one object to slide over another is known as static frictional force.
If the applied force is greater than static frictional force, the object will start moving over the other.
Therefore, static frictional force is the minimum force that must be overcome for one object to slide over another.

1. Compare neutron stars and black holes.
2. explain the role of white dwarfs in recycling matter
3. Distinguish between an astronomical unit and a light year
4. How does a convection zone transfer energy?
Thanks!
Answer:
1. Both neutron stars and black holes are the corpses of stars that died in explosions known as supernovas. Black holes form when the most massive stars die and neutron stars form when stars not as large die. They both have a very strong gravitational pull, but a black hole's pull is stronger than a neutron star. Neutron stars will turn into black holes if the force of gravity breaks the resistance of electrons.
2. White dwarfs are degenerate, which means they can compress matter. The material in a white dwarf no longer undergoes fusion reactions, so it is supported only by electron degeneracy pressure. This causes it to be extremely dense, saving space and energy.
3. A light year is the distance light travels in a year while an astronomical unit is the average distance between the earth and the sun.
4. A convection zone transfers energy by radiation and conduction.

What is the importance of forest to the stability of ecosystems and why does deforestation still take place despite the negative impacts?
Answer:
Deforestation not only removes vegetation that is important for removing carbon dioxide from the air, but the act of clearing the forests also produces greenhouse gas emissions. The Food and Agriculture Organization of the United Nations says that deforestation is the second-leading cause of climate change.
Answer:
Forests help provide many essential resouces such as wood, leafs, bark, food, oxygen, and maybe water if their are lakes. For the second question, mostly human activity, and carbon dioxide happen to negatively affect the forests, people are the stimulis to deforestation.

The amount of Cytosine plus Guanine is 40%. What would be the amount of Adenine?
Answer:
30%
Explanation:
Considering that the amount of Cytosine added to the amount of Guanine is 40%, that explains that Cytosine and Guanine each equal to 20%.
Cytosine: 20%Guanine: 20%Now, the remaining bit is 60%. Since Adenine and Thymine both equal the same, that would mean: 60/2 = 30.
Adenine: 30%Thymine: 30%Cytosine and Guanine pair together and will always be equal to one another. The same goes for Adenine and Thymine. (A=T, C=G)
Always remember that you want it to total up to 100% at the end.

Fall and Spring Equinoxes occur when days and nights are equal in length.
Summer solstice occurs when the Earth's North Pole is tilted toward the sun.
Winter solstice occurs when the Earth's North Pole is tilted away from the sun.
The tilt and revolution of the Earth causes the seasons

According to the Northern Hemisphere, all the statements given are exactly true.
What is the Northern hemisphere?It is one-half of the earth that is located in the north of the equator. It has about 90 percent of the world's population and most of the world's land.
Equinox means the duration of day and night are equal in length. There are two equinoxes in a year when the sun moves across the celestial equator, which lies directly above the earth's equator. The summer solstice occurs when the earth's pole is tilted towards the sun and receives more sunlight in the northern hemisphere. Winter solstice occurs when the earth's north pole is tilted away from the sun and receives less sunlight. Overall, the tilting and revolution of the earth is the main reason for the causation of different seasons.
Therefore, all the given statements are true with respect to the northern hemisphere.

QUICK I NEEE HELP !!!
Answer:
All cells come from existing cells
Explanation:
only answer that is part of the cell theory as far as i know
Please answer as soon as you can
Answer:
Differences in air temperature cause movement in the air, which creates pressure.
The radiant energy from the Sun is transferred to the atmosphere, causing air movement. The air becomes less dense, so it rises.
As the air falls, it becomes more dense and cools to Earth’s surface.
The higher the latitude, the colder the climate; the lower the latitude, the hotter the climate.

Answer:
A pH scale measures how acidic or basic a substance is.
Explanation:
The pH measures the H+ concentration in a substance. The more lower the pH, the more acidic the substance, the higher the pH, the more basic the substance. It measures from 0-14, with 7 being neutral. Anything less than 7, acidic. Anything above 7, basic.

Why solid melt when heated
Answer:
When a solid is heated the particles gain energy and start to vibrate faster and faster. Further heating provides more energy until the particles start to break free of the structure. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid.
