Weigh 10 grams of sugar and then dissolve in 100 mL of water (2
tools).
Answer:
180 gramsExplanation:
The solubility of sugar would be about 180 (a maximum of 180 grams of sugar can dissolve in 100 milliliters of water at room temperature). When a solvent has dissolved the most solute it is called a saturated solutionYou would need a scale to weigh it and a beaker/test tube to hold the water...
although farmers once used only organic fertilizers to replenish nutrients in the soils, some have been replaced with synthetic fertilizers. Although synthetic fertilizers keep nutrient levels high and increase crop yields, they can have an effect on the environment. Which of the following would most likely lead to a ban of synthetic fertilizers?
A. Synthetic fertilizers help prevent the spread of diseases.
B. Synthetic fertilizers are less expensive than organic fertilizers.
C. Synthetic fertilizers increase the potential for environmental pollution.
D. Synthetic fertilizers provide nutrients, like nitrogen that can disrupt nutrient cycling.
Answer: C. Synthetic fertilizers increase the potential for environmental pollution.
Explanation:
A fertilizer is a material which when applied to soil ,supply one or more plant nutrients essential to the growth of plants.
Fertilizers could be organic ( obtained from nature ) or could be synthetic ( made artificially in labs).
Though synthetic fertilizers such as urea keep nutrient levels high and increase crop yields but they also kill beneficial microorganisms in the soil that convert dead human and plant remains into nutrient-rich organic matter. The non biodegardable synthetic fertilizers seep into groundwater and increase its toxicity, causing water pollution.
Synthetic fertilizers damage the natural makeup of the soil. Plants that grow in soils which use synthetic fertilizers are deficient in iron, zinc, carotene, vitamin C, copper and protein.

According to the concept of "survival of the fittest," if a population of birds eats worms that they find deep under ground by using their beaks, birds that have longer beaks would be more likely to survive, which is present in Option B.
What is natural selection?Natural selection is a process in which the only organisms that can adapt to the environment and its changing conditions are chosen by nature, such as in the case of the Darwinian finches. when different types of birds are present in the ecosystem and all can get their favorable food source, but when an adverse climate occurs and food is only available in deep ground, only long-beaked birds can survive because they can get food. This explains the survival of the fittest by the natural selection.
Hence, as per “survival of the fittest," if a population of birds eats worms that they find deep under the ground by using their beaks, birds that have longer beaks would be more likely to survive, which is present in Option B.

Identify the natural processes that occur on the earth's surface to make and destroy rocks.
Answer:
You learned about the three rock types: igneous, sedimentary, and metamorphic. You also learned that all of these rocks can change. In fact, any rock can change to become any other type of rock. These changes usually happen very slowly. Some changes happen below Earth’s surface. Some changes happen above ground. These changes are all part of the rock cycle. The rock cycle describes each of the main types of rocks, how they form, and how they change.
The figure below shows how the three main rock types are related to each other (Figure below). The arrows within the circle show how one type of rock may change to rock of another type. These are the processes that change one rock type to another rock type.

Growers around the world produce about 3.2 x 107 metric tons of sunflowers each year. One
metric ton is the same as 1.1 short tons. How many short tons of sunflowers do worldwide
growers produce annually?
Answer:
3.5264 x [tex]10^{7}[/tex]
Explanation:
The metric ton is used as a unit of mass. The metric ton in British units can be represented as 2240 pounds or long ton whereas in United state is termed as 1.102 short ton.
In the given question, it has been mentioned that the growers around the world produce about 3.2 x [tex]10^{7}[/tex] a metric ton of sunflower.
So the short ton produced will be
= ( 3.2 x [tex]10^{7}[/tex] ) x 1.102
= 3.5264 x [tex]10^{7}[/tex] short ton.
Thus, 3.5264 x [tex]10^{7}[/tex] is the correct answer.

Why do disruptive selection pressures tend to favor rapid evolutionary changes?
a. They result in sudden gene frequency changes.
b. They eliminate extreme genetic traits.
c. They select for one variation of a genetic trait.
d. They result in environmental adaptation.
Answer:
The correct answer is a. They result in sudden gene frequency changes.
Explanation:
The evolution of life, its diversity, is reduced to the processes of microevolution or speciation. But not all evolutionary processes in populations end with the formation of a new species. Disruptive selection is a type of natural selection that selects against the average individual in a population. The composition of this type of population would show phenotypes (individuals with groups of traits) of both extremes but with very few individuals in between. Disruptive selection tends to increase intra-population variability and, to this end, favors individuals at both ends of the phenotypic distribution, that is, as a final result there is a break in two different populations, which can lead to speciation.

A"They result in sudden gene frequency changes."Explanation:

Which factor makes enzymes well-suited to the role of catalyst in a biochemical reaction?
A)Enzymes do not affect the energy of a reaction.
B)Enzymes slow down reactions so products can form.
C)Enzymes can be reused because they do not permanently bond with substrate.
D)Enzymes can only bind to other enzymes so the same product is formed each time.
Answer: C
Explanation: Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction.
Enzymes can be reused because they do not permanently bond with substrate.
What are Enzymes?
A biological catalyst called an enzyme is usually always a protein. It accelerates a certain chemical reaction in the cell. The enzyme is continuously employed during the reaction and is not destroyed. Each enzyme molecule found in a cell is unique and tailored to a particular chemical reaction.
Proteins called enzymes assist our bodies' chemical reactions move forward more quickly. For several processes, including digestion and liver function, enzymes are crucial.
Health issues might result from having too much or too little of a specific enzyme. Healthcare professionals can also use the enzymes in our blood to look for injuries and illnesses.
Therefore, Enzymes can be reused because they do not permanently bond with substrate.
