The San Marcos salamander, Eurycea nana, is a light reddish-brown
translucent salamander about 2-5 cm in length. E. nana is found only in
Spring Lake and a portion of the San Marcos River.
Which human activity would most likely decrease the ability of the
salamanders to survive?
The addition of a new food source into the river that limits competition for
resources
Tourism that helps fund the educational programs related to river ecosystem
conservation
Public transportation that reduces the number of automobiles that contribute to
pollution runoff into the river
Increasing water consumption that decreases the flow of clean water from the
springs that feed the river
Answer: Increasing water consumption that decreases the flow of clean water from the
springs that feed the river
Explanation: Because the salamanders have less clean water, pollution becomes more of a problem, also all of the other options would help the salamanders.
The human activity that would most likely decrease the ability of the salamanders to survive is increasing water consumption, which decreases the flow of clean water from the springs that feed the river, which is the last option.
What are the human activities that lead to habitat loss?The salamander is only found in a limited area of the San Marcos River, which relies on clean water from the springs, so decreasing the flow of clean water would negatively impact the salamander's survival, as it depends on specific water conditions for survival. As water is withdrawn from the springs to meet human needs, such as agriculture, industry, or household use, less water is available, which can have a detrimental effect on the habitat that the salamander requires because of human needs.
Hence, increasing water consumption decreases the flow of clean water from the springs that feed the river, so the last option is the correct option.

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.

ALL elements that make up glucose can be rearranged to make carbohydrates, proteins AND lipids.
True or False
Glucose is a simple sugar made up of 6 carbon, 6 oxygen and 12 hydrogen atom. It is an aldohexose because of the presence of the aldehyde group. It is the most abundant monosaccharide sugar.
The given statement is:
False.
The explanation for this is:
Carbohydrate is a molecule of biological importance and is made up of carbon, hydrogen and oxygen atoms. Hence, the elements of glucose can be rearranged to make carbohydrates.Similarly, lipids are insoluble bio compounds made up of carbon, oxygen and hydrogen.Proteins are molecules that are very crucial for cell functioning and structure. They are composed of carbon, hydrogen, oxygen and nitrogen mainly sometimes they even have sulfur or phosphorus in them.Therefore, the elements of glucose cannot be rearranged to carbohydrates, lipids and proteins.

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

Name THREE ways Earth’s oceans affect your life.
The ocean is good for animals, animals need the water and animals help the water in some type of way. And half of the people including me loves sea animals, so without the ocean, there will be no sea animals.
And the ocean is good because it produces oxygen and carbon dioxide.
Three ways by which Earth's ocean affects your life are it supplies freshwater (most rain comes from the ocean) and nearly all of Earth's oxygen. The ocean moderates the Earth's climate influences our weather and impacts human health.
What are the oceans' effects?It offers food, medications, minerals, and sources of renewable energy. Fishing, seafood, pleasure, and science are all supported by it. Our ocean is the first "super-highway," connecting economies and moving people and things around the world.
Animals benefit from the ocean, as they both need and contribute to the water in some form. And since I am one of the people that like sea life, there wouldn't be any sea life without the ocean.
Therefore, additionally, the ocean is beneficial since it emits carbon dioxide and oxygen.

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.

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.
