Answer:
it would be half the the gravitational attraction(D) because the distance Has doubled.
If the mass of the moon were doubled and the distance between them is also doubled, then it will have half the gravitational attraction. The correct option is D.
What is gravitational force?The gravitational force is basically a force that attracts any two mass-bearing objects. The gravitational force is called attractive because it always tries to pull masses together rather than pushing them apart.
According to Newton's law of gravitation, the force of gravitation is inversely proportional to the square of the distance between the bodies. Thus, doubling the distance reduces the force of gravitation by 1/4.
If one of the objects' mass is doubled, the force of gravity between them is also doubled. If one of the objects' mass is tripled, so is the force of gravity between them. If the mass of both objects is doubled, the gravitational force between them is quadrupled, and so on.
Now, here, the mass is being doubled which is making the gravitational attraction doubled. But distance is also increasing by two.
So in this case, the gravitational attraction will get 1/4, so the net attraction will be half.

Only plants can photosynthesize, and only animals can perform cellular respiration
O True
O False
Answer:
false, plants and animals perform cellular respiration but only plants can photosynethesize.
Explanation:
Only plants can photosynthesize, and only animals can perform cellular respiration. The given statement is false.
What the process of cellular respiration involves?
The process of cellular respiration involves the oxidation of biological fuels in the presence of an inorganic electron acceptor, like as oxygen, to generate significant quantities of energy that are used to power the major creation of ATP. The process of converting chemical energy from foods into adenosine triphosphate (ATP) in an organism's cells, followed by the discharge of waste products, is known as cellular respiration.
During catabolic processes, which divide big molecules into smaller ones and release energy, respiration takes place. One of the main mechanisms through which a cell produces chemical energy to power cellular activity is respiration. A sequence of biochemical stages, some of which include redox reactions, make up the total process.
Therefore, Only plants can photosynthesize, and only animals can perform cellular respiration. The given statement is false.

how do enzymes speed up chemical reactions
3 ways
also one of them is lower activation energy and idk what else
Answer:
Enzymes lower the activation energy of a reaction by...
making the molecules' transition state stableproviding alternate reaction pathwaysdestabilising substratesExplanation:
Enzymes are complex, folded protein structures - in biological processes they facilitate chemical reactions.
Molecules usually collide at random, and specific chemical reactions (breaking and forming bonds) require the correct molecular orientation and energy to react. Enzymes..
provide an alternate reaction pathway with lower energy requirements. stabilize the molecules, keeping them in their transition states til they can react- these usually enter short lived, reactive and high-energydistort the substrate. These slightly alter their typical structures- bonds under stress are easier to manipulate and break, requiring less energy input for changes later onTime and large amounts of energy, are needed to arrive at these orientations to allow the reactions to occur- this is a barrier called activation energy.
Thus, enzymes help by lowering the activation energy needed for the reaction (e.g. hydrolyzing a bond) to progress, and they increase the rate of chemical reactions.

Answer:

Explanation:
Just took the quiz
The statement that best describes the role of plate tectonics in changes that occur on earth is that the movement of plates builds pressure that is released during an earthquake, which is option a.
What is plate tectonics?Plate tectonics is the theory that explains the large-scale movements and interactions of the Earth's lithospheric plates, which make up the outermost layer of the Earth. These plates are made up of both the crust and the uppermost part of the mantle, and they move and interact with each other over time. The movement of plates is driven by convection currents in the Earth's mantle, which is the layer of hot, molten rock that lies beneath the crust. These currents cause the plates to move apart from each other at divergent plate boundaries, where new ocean crust is created.
Hence, the correct answer is that the movement of plates builds pressure that is released during an earthquake, which is option a.

What is a chemical reaction?
A chemical reaction is a chemical change occuring for matter where the atoms are regrouped into new products through bond making or bond breaking or both.
The change in energy during a reaction is called enthalpy change, where each reactant is associated with a standard energy and the energy may change with temperature or other external factor.
There may more than two reactants and some reactions are completing through several stages and may lead to complex products which are having entirely different properties from the reactants. Therefore, all the given statements about chemical reactions are correct.

The southern United States experiences periodic occurrences of severe cold and drought conditions. Which weather phenomenon most likely causes this and why?
La Niña, because the jet stream is displaced southwards
La Niña, because the jet stream is displaced northwards
El Niño, because of increased upwelling of cooler waters
El Niño, because of decreased upwelling of cooler waters
Answer:
D give Brainlist
Explanation:
La Nia is a climatic phenomenon that causes the surface ocean water temperature along South America's west coast to decrease. It causes the sea water's temperature to be lower than usual, hence option D is correct.
Why are periodic occurrences of severe cold and drought conditions?Lower temperatures lead the central and eastern Pacific to have higher than usual pressure, which reduces rainfall. Due to up-welling, rainfall decreases as cloud formation does.
The "ENSO," also known as the El Nino-Southern oscillation, is a cyclical climate phenomenon that periodically affects the tropical Pacific. Its warm and cool periods are called El Nino and La Nina, respectively.
Therefore, the trend switches back and forth occasionally every two to seven years, disrupting tropical wind and rainfall patterns, hence option D is correct.
