Explanation:
The structures responsible for completing the breakdown of carbohydrates into usable energy for the cell are the
A. Nuclei
B. Mitochondria
C. Ribosomes
D.chloroplasts
Answer:
The correct option is;
B. Mitochondria
Explanation:
The mitochondria are the organelle of the cell bund to the membrane that are referred to as the cell powerhouse they function in the same manner as the digestive system, such that they take in raw nutrients which are broken down to produce energy containing molecules which makes up the majority of the chemical energy required for the various biochemical reactions of the cell in a way such that the energy they produce are stored in adenosine triphosphate (ATP) molecules.
Answer:
B. Mitochondria
Explanation:
The mitochondria are cellular organelles found in eukaryotic cells. They are structures involved in cellular respiration, which is the process whereby energy in form of ATP is synthesized for use by the cell.
Cellular respiration in eukaryotes occurs in stages including glycolysis, kreb's cycle and oxidative phosphorylation. All these processes combine to breakdown carbohydrates (glucose) into usable energy for the cell. The structures responsible for this process is MITOCHONDRIA.
if your poop is green, is that a good thing or a bad thing.
Answer:

During a chemical reaction, increasing the temperature often
OA increases the rate of chemical change.
ОВ.
decreases the rate of chemical change
OC.
reverses the direction of chemical change.
OD. prevents a chemical change from occurring.
Answer:
A increases the rate of chemical change.Explanation:
Elements undergo chemical bonding-where electrons are shared, and rearranged to form various molecules and compounds. Bond formation in chemical reactions have specific requirements for molecular configurations and energy.
Molecules usually collide at random til conditions are favorable for bonding. Chemical change or reactions occur at faster rates at higher temperatures. Heating molecules increases their collision frequency and makes it more possible for the correct molecular orientation (for breaking and forming bonds) and energy to react are present.

O a. Humans depend upon other organisms for food and oxygen
b. Species have value to humans, both monetary and because we like them
c. Tourism depends on the preservation of certain animal species
d. Both (a) and (b)
Answer:
a) Humans depend upon other organisms for food and oxygen
Explanation:
Biodiversity refers to the richness in the species of organisms on Earth i.e the variety of biological organisms on the Earth. The importance of biodiversity cannot be overemphasized because of our dependence on the sustainability of biodiversity in our ecosystems.
The loss of biodiversity, which is becoming rampant by the day, is a major concern to us because we humans depend upon other organisms for food and oxygen. Humans are strictly heterotrophic and hence are reliant on variety of organisms for food. Plants also release oxygen gas via their photosynthetic process, which is key to our survival as a population.
The study of the environment is called ecology.
The correct answer is A.
The loss of animals and plants in the ecosystem is called loss of biodiversity. These reasons for the loss is as follows:-
Overexploitation.Invasion of alien speciesGreedHabitat lossThe loss of these species has a high impact on the ecosystem as these have an important function to form forests.
All the species are dependent on each other.
Hence, the correct option is A that is humans depend upon other organisms for food and oxygen

Which option describes a similarity between scientific laws and scientific theories? 1.Both can change in light of new evidence. 2.Both explain how a phenomenon works. 3.Both are purely observations of nature. 4.Both are suggested explanations that are starting points.
Answer:
1.Both can change in light of new evidence
2.Both explain how a phenomenon works
Explanation:
Law and theory can be defined to be part of the nature of scientific knowledge. A scientific theory is a well-established explanation for observations of the natural world which can be verified by applying the scientific method, while a scientific law is a statement obtained from repeated experimental and/or observational procedures to describe and/or predict natural phenomena. Scientific theories can change when researchers discover new lines of evidence, while scientific laws also change based on new empirical evidence.
