Which features results when plates of different densities converge and one
plate slips under the other?
Explanation:
Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. ... Subduction zones are sites that usually have a high rate of volcanism and earthquakes.

4. How does ADP get converted to ATP?
5. Which molecule has a higher potential energy. ADP or ATP?
Answer:The ATP molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule.
Explanation:
The left side of the diagram is adenine, the middle part is ribose which is a sugar.
A sugar molecule is composed of 12 carbon, 22 hydrogen, and 11 oxygen atoms that is made the structure of the sugar.
In ATP molecules, energy is stored in the covalent bonds that is present between phosphates. The greatest amount of energy is present in the bond between the second and third phosphate groups.
ADP is converted to ATP by the addition of a high-energy phosphate group to ADP making it ATP.
ATP has more potential energy than ADP. ATP has three negatively charged phosphates whereas ADP has two phosphates.

Why are there so many tornadoes in Central Texas, lowa, Kansas, Nebraska, and
east to Ohio, which is referred to as Tornado Alley?
The topography of the land allows winds to increase in speed, causing the
development of tornadoes.
Storms are caused when dry cold air moving south from Canada meets warm
moist air traveling north from the Gulf of Mexico.
It is the result of Climate Change and the Greenhouse Effect.
Wildfires deplete the atmosphere of oxygen creating a funnel, which develops
into a tornado.
The answer is Storms are caused when dry cold air moving south from Canada meets warm moist air traveling north from the Gulf of Mexico

A) El agua es imprescindible para la vida porque... Regula los valores de temperatura humedad en los medios terrestres Es el medio perfecto para que habiten muchos organismos Contiene disuelta todas las sustancias que necesitan los seres vivos Todas son correctas
Answer:
Todas son correctas
Explanation:
El agua (H2O) es una molécula clave que forma parte de los ecosistemas naturales y cuya presencia es crítica para el sostenimiento y la reproducción de la vida en la Tierra, ya que solamente este compuesto permite llevar a cabo procesos biológicos y reacciones químicas que hacen posible la vida. El agua es el principal componente del cuerpo en todos los seres vivos, representando el 65% del cuerpo en el hombre, 95% en una medusa, 90% en un hongo o 90-95% en la mayoría de las plantas. De este modo, el agua es imprecindible para la vida tal y como la conocemos. Además, el agua es un componente abundante en los ecosistemas naturales y alrededor del 70% del planeta está cubierto por agua, siendo este un ambiente propicio para el sostenimiento de la vida de una gran parte de los organismos que habitan la Tierra. Finalmente, el agua es una molécula polar que constituye un poderoso disolvente en estado líquido para diferentes sustancias tales como, por ejemplo, ácidos, álcalis, azúcares y gases incluyendo el oxígeno (O2) y el dióxido de carbono (CO2).
Describe the lithosphere and its role in plate tectonics.
The lithosphere,which is the rigid outermost shell of the planet(the crust,and upper mantle),is broken into tectonic plates.The earth's lithosphere is composed of seven or eight major plates(depending on how they are defined)and many minor plates.In this way,the total surface of the lithosphere remain,the same.
The upper mantle, crust, and lithosphere, the planet's solid outermost shell, are divided into tectonic plates. Depending on how they are classified, the lithosphere of the earth is made up of seven or eight major plates as well as several lesser plates. The lithosphere's overall surface remains constant in this fashion.
What lithosphere and its role in plate tectonics?In terms of plate tectonics, the lithosphere serves as the “plate.” Seismic waves enter the warm, plastic Asthenosphere at a slower speed in this "low-velocity” seismic zone, which denotes the base of the lithospheres. With a property known as plastic behavior, the Asthenosphere (weak sphere) is a component of the flowing Mantle.
Therefore, In plate tectonics, the Earth's lithosphere, which is composed of the crust and upper mantle, is divided into sizable rocky plates. These plates are situated on top of the asthenosphere, a rock layer that is still partially molten.

Suppose you must design an experiment to test how a paper airplane's shape affects the distance will fly. Your plane must fly halfway across your classroom to get the best grade. The teacher reminds you to use both imagination and logical reasoning in your design.
Answer:
First I would make controls for the experiment, for example:
-Each plane must be one piece of paper
-No tape
Then make categories for certain shapes of planes, for example:
-Folding longways or shortways (that's a word right?)
-Wing length between 6-8 cm is one category, 8-10 is another category
-Test if a folded nose or pointed nose of the plane works better
-Find professional designs and test which long-distance one is the best
Bananas (and other fruits) change as they ripen.
What happens to the carbohydrate molecules in the fruit as they ripen?
1. Use the tests to identify how the 2 different carbohydrate molecules change in the banana from unripe to ripe. (You will need to run both the Carbohydrates tests - One that tests for glucose and one that tests for starch for BOTH the unripe banana AND the ripe banana and record the results below).
2. Based on how you like your fruit (ripe or unripe), make a claim about how each of the different molecules tastes (sweet or unsweet-- think about which carbohydrate tastes more sweet starch or glucose?).
HELPPPPPPPPPP
Answer:
What happens to the carbohydrate molecules in the fruit as they ripen?
During ripening, there is an increase in the breakdown of starch inside the fruit, and a corresponding increase in the amount of simple sugars which taste sweet, such as sucrose, glucose, and fructose. This process is particularly obvious in bananas as they ripen. Green bananas do not taste sweet at all, and the riper they get, the sweeter they taste. There is also a decrease in acidity as the fruit ripens and a decrease in bitter plant substances, such as alkaloids. Last, as fruits ripen they produce complex compounds that are released into the surrounding air, giving a ripe fruit its pleasant aroma.
The breakdown of complex carbohydrates in the fruits increases in the fruits as they ripen.
What happens to ripened fruits?When fruits are growing on the plants, the plant is constantly providing them with water and nutrients for their development. Initially, the growing fruits are protecting the seeds inside them.
In the growing stage, fruits are not edible and do not attract predators. This allows the fruit and the seed inside it to develop properly.
After completion of seed development and the growth of fruit, it changes in appearance to attract consumers including birds, humans and animals.
The fruit also starts to get softer as the cell wall begins to break down. The cell wall is made up of complex carbohydrates with glucose as its monomer.
The cell wall is broken down by the protein enzymes that accompany the fruits as they ripen.
Therefore, the breakdown of complex carbohydrates in the fruits increases as they ripen.

A mutation causes a tomato plant to have much fewer, smaller leaves. Plants use their leaves to make food. Which best describes this mutation? It is harmful because it obviously affects the plant’s ability to survive. It is beneficial because it affects the plant’s physical appearance. It is neutral because it does not obviously affect the plant’s ability to survive. It is neutral because it affects the plant’s physical appearance.
Answer:
It is harmful because it obviously affects the plant’s ability to surviveExplanation:
Mutations are alterations in the genetic code that may occur due to environmental or chemical mutagens. Mutagens, are substances or agents that induce changes in the genetic code.
Photosynthesis is a complex biochemical process; plants convert solar energy into chemical energy as sugars like the polysaccharide glucose. They also use inorganic carbon from [tex]CO_{2[/tex] along with [tex]H_{2}O[/tex].
Plants photosynthesize in their leaves- these organs contain tissues for [tex]CO_{2[/tex] intake, along with the chloroplasts and mitochondria, the sites of photosynthesis and respiration. If the number of leaves are reduced, this reduces the amount of tissue capable of carrying out this essential process, limiting the plant's chance for meeting its energetic needs, and thus survival.
