Answer:

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.

Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.

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.

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.

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:-

The 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
