Read the scenario.

A biologist is studying golden frogs that live in cool streams running through the rain forests of Central America. The biologist conducts a survey of the population and counts over 100 frogs in one mile of stream. The biologist returns to the same location one year later and counts only 20 frogs in that same stretch of stream. The biologist wonders why there are suddenly so few golden frogs.

The biologist also observes that a mining company has set up a copper mine only a few miles from the stream. By reading studies on copper mining operations in other parts of the world, the biologist learns that the wastewater runoff from the mines is highly acidic and contains potentially toxic compounds.

Which part of the scientific method is best illustrated by the biologist wondering why there were so few frogs in the second year compared to the first?

a making an observation and asking a question

b collecting data

c setting up an experiment

d forming a hypothesis

Answer:

According to psychologist Gordon Allport, social psychology uses scientific methods "to understand and explain how the thoughts, feelings, and behavior of individuals are influenced by the actual, imagined, or implied presence of other human beings." What social psychology does is that it teaches us how people's social behavior is, and how we can match certain aspects of our emotions to uncalled attitudes. For example, someone may lash out at someone they truly love when they don't mean it, solely because they are upset. Social psychology can teach us how our feelings are coordinated with our beliefs and how we can react to them appropriately.

Explanation:

Answer:

Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence

Explanation:

Scientific methodology includes the following: Objective observation: Measurement and data (possibly although not necessarily using mathematics as a tool) Evidence.

Answer:

Yes, that is correct

Explanation:

The bond between monomers of carbohydrates, e.g. glucose and fructose is a glycosidic bond-forming in this case a sucrose molecule (disaccharide). A glycosidic linkage is a C-O-C bond (ether). The underlying reaction is a condensation reaction where 1 OH- and 1 H+ are split off resulting in the formation of H2O.

Explanation:

The cell cycle directly follows prophase is metaphase.

A cell's growth and division are accompanied by a sequence of processes known as a cell cycle. A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide.

The cell then exits interphase, goes through mitosis, and finishes dividing. Each of the resultant cells, referred to as daughter cells, enters its own interphase to start a fresh cycle of the cell.

The procedure through which cells multiply and divide into two new cells as the cell cycle. G1, S, G2, and M are the phases of the cell cycle, respectively. Cells are getting ready to divide at the G1 stage.

Therefore, The cell cycle directly follows prophase is metaphase.

Answer:

d) trace minerals

Explanation:

Boron (B) and molybdenum (Mo), two of the seven essential micronutrients, also known as trace elements, are required for the normal growth of most plants.

researchgatenet

Boron and molybdenum are essential nutrients classified as trace minerals. Therefore, option D is correct.

An important nutrient is one that the plants cannot produce on their own or cannot produce in sufficient levels for basic activities, hence it must be obtained from the environment in order for the plant to function normally.

Essential elements are classified into two categories on the basis of the requirements of the plant and those are macro nutrients and micro nutrients. Macro minerals contain oxygen, nitrogen, sulfur, hydrogen, magnesium, manganese, and carbon. Microminerals contain boron, molybdenum, and zinc.

Thus, boron and molybdenum are essential nutrients classified as trace minerals. Therefore, option D is correct.

catabolic pathway/ catabolism

Explanation:

The energy profile diagram shows an exothermic or exergonic process - as the process releases energy. Catabolic reactions breakdown larger molecules into smaller ones, giving off energy. For example the glycolysis.

The supply of fresh water is increased.  Therefore, option (B) is correct.

Desalination is the process of removing salt and other minerals from seawater in order to make it suitable for drinking or irrigation. There are several different methods of desalination, including reverse osmosis, thermal distillation, and electrodialysis. These processes are used to produce fresh water from seawater in areas where there is a shortage of fresh water resources.

Desalination can be an effective way to increase the supply of fresh water in areas that are prone to drought or have limited access to other sources of water, but it can be expensive and energy-intensive.

Comminution

 In order to separate the valuable components of an ore from the waste rock, the minerals must be liberated from their interlocked state physically by comminution.

The step that immediately follows separating the mineral from the waste rock during the mining process is crushing and milling. Therefore, the correct statement is option C.

When the mineral gets separated from the waste rock in the form of large chunks, it further needs to be processed before it can be used. Crushing and milling break down the mineral into smaller pieces, which are easy to be processed early and refined.

Crushing uses mechanical force to break down the mineral, while milling grinds the mineral into a fine powder using heavy machinery such as crushers, ball mills, etc.

After the crushing and milling process, the mineral is more suitable for further processing, which involves additional steps such as flotation, leaching, etc. The final product formed is then distributed to the market.

Therefore, crushing and milling involve separating the mineral from the waste rock during the mining process.
