Which organelle is the powerhouse of the cell
Answer:
The mitochondria
Explanation: Mitochondria (sing. Mitochondrion) are known as the powerhouse of the cell because they are responsible for the release of energy from food ,i.e, cellular respiration. This energy is released in the form of ATP (adenosine triphosphate), the energy currency of the cell.

What is natural selection? Is it similar to survival of the fittest? How are the 2 alike? How are they different?
Answer:
Difference: Survival for the fittest is the survival of species/organisms with genes better suited to the environment and are selected for survival and passed to the next generation while natural selection works by giving species who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted.
Explanation:
Evolution is the slow/gradual development of human beings from simple life forms into higher forms of life over millions of years ago as stated by Charles Darwin in his book 'The Origin of Species' in 1959. He argues that human beings evolved from simple life forms into higher forms of life through:
1.Mutation - abrupt change in the form of a living organism as dictated by the climate or genetic components of the living thing involved.
2.Natural selection - a process in which the stronger species out compete the weaker ones for resources (Survival for the fittest).
3.Environmental adaptation - follows after the first two, where the surviving species isolate themselves from others as they adapt to the new environment.

Question 9 options:
Both of these
None of these
Relative dating
Radiometric dating
Scientists can determine the exact age of a fossil by a technique called Radiometric dating. Radiocarbon dating involves the determination of how much carbon is left in the fossil.
In radiocarbon dating, it is possible to determine how much carbon is left in the fossil, by looking at its half-life period.
Radiocarbon dating (also known as carbon dating) refers to the technique aimed at determining the age of a fossil by exploring the properties of a radioactive carbon isotope called radiocarbon.
Radiocarbon or carbon-14 (14C) is a radioactive carbon isotope of carbon that contains 6 protons and 8 neutrons, whose amount in a sample can de be used to determine the age of a given organic material.

How and why does the surface of the earth change
of the earth has changed?
Answer:
How and why does the surface of the earth change
of the earth has changed?
It can be hard to describe change on the surface without bringing up the interior. Earth is a system of constantly changing interactions between interior, surface conditions, and external events.
Volcanoes bring up new material and even create land. The Hawaiian islands, for instance are a chain of volcanoes on the surface, but the underlying structure is a single magma plume. In a way, the entire chain of islands is a single volcano that breaks through different places as the crust moves over it.
On that note: plates. Earth is made of tectonic plates that constantly move. Some grind against one another, others collide, and some pull apart. Depending on direction and interaction, you get anything from mountains, to spreading valleys, oceans, and anything else you care to name. Mountains can almost be viewed as something akin to the ridges of build up ice on a window scraper.
Erosion by water, wind, sand, chemicals, and living things changes the surface too. Materials on the surface face an incredible number of forces breaking them down and dragging them away, even as those same forces in different places and situations deposit those materials in other places, building things back up.
“Stardust” is also a thing. Rocks, dust, debris, and all sorts of random, natural cra.,p is constantly hitting our atmosphere. Regardless of whether or not it stays mostly intact, some material breaks off, and most of it does tend to make it to the surface, adding tiny amounts of matter all the time. …of course something BIG enough hitting the surface can throw rocks and chunks of surface clear into space, so that’s a thing too.
Remember when I mentioned living things? Living things D.,IE! Gac.k! And when they do, they break down into organic gunk. Soil - the stuff we grow crops in - is basically minerals and dead things that are decaying into nutritious, yummy, dir.,t.
Weather changes things too. Rain erodes, but rain that soaks a rock, and then is frozen by low temperatures, breaks the rock. Too much rain can create flooding, which results in a lot of sediment moving downstream. Heat can dry things out, crack the ground, and even slowly cook one kind of soil into another. Lightning can make glass out of sand, snow can collapse weak ground, not enough rain can dry out ground that could si.nk down without the extra pressure, and too much rain can literally move mountainsides if enough water adds its weight to the rocks and dir.t.
It’s always changing, and there is always more complexity to go into when studying it. There’s seldom a single cause, or reason, or effect for anything.
Explanation:
Have a great day!
The surface of the earth is constantly changing.
Explanation:
Wind, water,and ice break down large rocks and move sediments on the surface. Some events, though, change earth's surface much more quickly. These include volcanic eruptions, earthquakes, and landslides.
In which state elements occurs?
An element is said to exist in free state if it does not combine with any other element. Rather, free state elements are stable even without combining.
The Maine Department of Transportation (DOT) has a fleet of roughly 400 plow trucks that are used to control snow and ice on approximately 8300 lane miles of Maine’s state roads. They usually plan on an average of about 30 treatable events in a winter. This includes the use of rock salt, salt brine and winter sand, a mix of sand and salt. Salt brine is used on roads and bridges prior to a storm to delay ice and snow from sticking to the roadway and is also used in plowing to fight the buildup of ice and snow throughout the storm. Rock salt helps keep roads safe when winter storms hit, reducing winter road accidents, but it can also have negative effects on plant life and aquatic ecosystems. What are the environmental effects of salting that must be mitigated? Select ALL that apply.A) Salt kills roadside plants. B) Salt builds up in roadside soil , changing its pH, preventing the growth of plants. C) Salt corrodes metals like automobile brake linings, frames, and bumpers, and can cause cosmetic corrosion. D) Elk, moose and sheep eat road salt causing "salt toxicosis" where they lose their fear of vehicles and humans, causing many fatal encounters. E) Salt doesn't evaporate, or otherwise get removed once applied, so it remains a persistent risk to aquatic ecosystems due to runoff or ground

That is option B and E.
The effects of road salting on the environmentRoad salting is a technique that is used to melt snow and ice during winter season. This keeps the streets and side sidewalks clear and prevents slick driving conditions.
The types of salt used for road salting include:
rock salt, salt brine,winter sand, a mix of sand and salt.The impact of road salting on the environment include the following:
Decrease in reproduction and growth of plants: This is because increase salinity are toxic to plants and as the concentration of these ions increases, the plant is poisoned and dies.Negative effect on aquatic ecosystems: This affects mostly the freshwater ecosystems as high levels of salt are very toxic to the aquatic organisms.Learn more about aquatic ecosystems here:

The group of components of the Earth work together to make an environment we live in.
What are the different components of the Earth?The interactions between Earth's five systems—the geosphere, biosphere, cryosphere, hydrosphere, and atmosphere—create the environment we are accustomed to.
The Earth's interior and surface, which are both formed of rocks, make up the first system, the geosphere. The second system is made up of the little area of the planet that may sustain life; this area is known as the biosphere. The third system contains the hydrosphere, or regions of Earth that are completely covered with water. The fourth system is the atmosphere, a gaseous envelope that maintains the planet's temperature while also supplying carbon dioxide for photosynthesis and oxygen for breathing. The cryosphere, which is composed of enormous amounts of ice in the poles and elsewhere, is the fifth system. The maintenance of the Earth as we know it depends on the interaction of all five of these vast and intricate systems.
