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

What has the most control over water being a gas, liquid or solid ice? A. The amount of water B. It’s temperature C. If its being used D. It’s age
Answer:
B. Its temperature
Explanation:
The different states of matter are largely influenced by both temperature and pressure. The temperature has most control over water being a gas, liquid or solid ice. If the temperature is very high, the molecules in the water increases their kinetic energy. This movement causes the compound ([tex]H_{2} O[/tex]) to break its bond. Thus, it turns into a gas. On the contrary, if the temperature is very low, the molecules of the water moves closer to each other. This causes them to solidify and turn into ice.
Franklin was performing an experiment by combining hydrochloric acid and sodium hydroxide. He measured the mass of his reactant materials to be 35g. The reaction resulted in the production of salt and water. He reported that his products weighed 32g. Which best describes the results of Franklin’s experiment? No error occurred, some of the products are always lost as heat. An error occurred, the mass of the reactants should equal the mass of the products. An error occurred, the products should weigh more than the reactants. No error occurred, water is not weighed when determining the weight of the products.
Answer:
B) an error occurred, the mass of the reactants should equal the mass of the products.
Explanation:
The answer choices are:
A) no error occurred, some of the products are always lost as heat.
B) an error occurred, the mass of the reactants should equal the mass of the products.
C) an error occurred, the products should weigh more than the reactants.
D) no error occurred, water is not weighed when determining the weight of the products.
Solution
The basis to answer this question is the law of conservation of mass.
Any chemical reaction satisfies the law of conservation of mass: mass cannot be either created nor destroyed, so, always, the mass of the reactants equal the mass of the products.
Thus, since he measured the mass of his reactant materials to be 35g and he reported that his products weighed 32g, his data are in clear contradiction of the law of conservation of mass. So, there is an error in his results: the mass of the reactants should equal the mass of the products.

Which statement best describes how the Great Rift Valley in Africa formed?
The rift valley formed when the crust pulled apart.
The rift valley formed due to subduction.
The rift valley formed similarly to an island arc.
The rift valley formed at a convergent boundary.
Answer:
The rift valley formed when the crust pulled apart.
Explanation:
The Great Rift Valley in Africa formed when the crust pulled apart along a divergent margin.
Rift valley systems are produced within a continent at divergent margins within a plate. The rifting system makes the earth in that region prone to frequent earthquakes as the continents continues pulling apart. It results from the divergence of the Arabian plate and the Somalia/Nubian plate. It is one of the longest rift valley systems on earth.Answer: a. The rift valley formed when the crust pulled apart
Matter and Chemical Formula
Let us learn about
Atoms and molecules
Element, compound and mixture
Chemical symbol and chemical formula
Atomicity and valency
Answer:
Atoms are the basic units comprising matter, and interact in a variety of ways.
Explanation
The most fundamental unit of matter that makes up elements is called atoms. Atoms comprise nucleus-orbiting electrons- while protons and nuetrons make up a stable nuclues. Here, the neutrons are uncharged, while the negatively charged electrons are attracted to the positively charged protons at the atom's center
The number of protons the atom determines its atomic number, and the sum of protons and neutrons determine the atomic mass.
Elements in the periodic table, are typically represented by chemical symbols- abbreviations of their atomic name. They are arranged in order of valency- atoms in the same group typically have the same number f electrons on their valence shells, and thus their physical properties behave similarly (conductivity, melting points, boiling points).
Valence electrons, on outer valence shells, also influence bonding. The atoms donate, accept or share valence electrons in order to achieve more stable atoms. Bonding between elements form molecules, that may interact with molecules to form compounds.
