This relationship is called complementary bases paring. These complementary bases are bonded together via hydrogen bonds, which can be easy broken apart what the DNA need to unzip and duplicate itself
After a community is disrupted by a large-scale event, such as a forest fire, a new community is established through
which process?
a. climax succession
b. secondary succession
c. primary succession
d. soil formation
After a community is disrupted by a large-scale event, such as a forest fire, a new community is established through secondary succession The correct option is b.
What is secondary succession?Secondary succession occurs when a disturbance affects a climax or intermediate community. This restarts the succession cycle, but not all the way back to the beginning soil and nutrients are still present.
When the severity of a disturbance is insufficient to remove all of the existing vegetation and soil from a site, secondary succession occurs.
Secondary succession can be initiated by a variety of disturbances, including fire, flooding, windstorms, and human activities (for example, logging of forests).
Tropical forests gain structural complexity, taxonomic diversity, and functional diversity during secondary succession.
These changes result in the accumulation of carbon and nutrients in aboveground vegetation, as well as the creation of habitat for forest animal species.
Thus, the correct option is b.

B) Chemical reactions involve changes in the energies of the molecules involved in the reaction
C) Organisms take in the matter and rearrange those atoms during chemical reactions.
D)Both A and B
E)All the Above
chemical reactions involve changes in the energies of the molecules involved in the reaction
During a chemical reaction, bonds are formed or breaked to make new products which may complex than the reactants. Energy changes can be happened in a reaction during rearrangement of atoms. Thus, all of the statements are correct.
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.

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.
which statement best describes the role of plate tectonics in changes that occur on earth
A. the movement of plates builds pressure that is released during an earthquakes
B. convection currents in the mantle cause mountain ranges to slowly collapse over time
C. the subduction of oceanic crust cools the mantle and prevents volcanic eruptions
D. seafloor spreading causing ocean basins to get smaller and shallower over time
Answer:
A
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.

If an organism is eukaryotic, many celled, can move and cannot make it owns food but must hunt or gather food, which kingdom would it be be placed into?
Answer:
Kingdom Animalia
Explanation:
An organism that is many-celled, can move, and cannot make its own food but must hunt or gather food would be placed in the kingdom Animalia.
Animals are generally heterotrophic, multicellular, and are able to move from one place to another. They ingest their foods and carry out digestion within their bodies and egest out undigested foods.
Animals are different from plants primarily in that they cannot make their own foods through photosynthesis. They are different from fungi in that they cannot carry out extracellular digestion of foods. Also, animals are different from bacteria and protists in that they multicellular rather than being unicellular.
