A student wants to create a liquid volcano. The student observes bubbles in the soft drink prior to opening it.
The student first proceeds to open the soft drink bottle and place it on the floor.
Next the student drops candy tablets into the drink using a rolled piece of paper, so that the tablets are able to fall into the drink continuously. The student notices a very powerful reaction as the drink fizzes and starts to bubble.
In this scenario, what would be the catalyst ?
The candy tablets being added to the drink.
The gasses being released when the drink was first opened.
The piece of paper being placed over the soft drink.
The container that holds the liquid.
A. The candy tablets being added to the drink.
Right after the student proceeds to open the soft drink bottle and places it on the floor, they add the candy tablets into the drink. Notice how they notice the fizzes after the candy tablets were dropped in.
Your answer should be A.

paragraph about what life would be like if we had no minerals available.
Answer:
Minerals make up most of what we use to build, manufacture and stand on — including rocks and soil — so if we really ran out of minerals, we'd all be scrambling for a spot on the planet's shrunken surface areas. But if we were to run out of a mineral — as in, exhaust our supply — it probably wouldn't be because there's none of it left on Earth. The problem would be that the processes used to extract it have become too expensive, difficult or harmful to make mining worthwhile. Even then, as mining technology advances, previously inaccessible minerals will become available and lower-producing ores will be processed more efficiently.

How do single celled organism lives and grows
Answer: Growing is capable to a certain living organism. Growth means getting larger in size, and for multi-cellular organisms this is done by making more cells. Plants have special tissues called meristems where growth occurs. Single celled organisms increase their numbers by dividing and making more cells like themselves.

Which model best shows the movement of water during photosynthesis?
A. Atmosphere →plant
B. Soil → Plant
C. Atmosphere → Soil
D. Plant→ Soil
Answer:
B.
Explanation:
I picked it and it said B was the right answer.
Water is taken up by roots from the soil and moved as a liquid by xylem to the leaves. Small holes in the leaves allow CO2 to enter the leaf for photosynthesis and water to escape as a vapor. Thus option B is correct.
What is movement of water during photosynthesis?Water moves through a plant during transpiration, where it evaporates from aerial parts like leaves, stems, and flowers.
Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis.
Water molecules pass through a membrane during osmosis from an area of higher concentration to a region of lower concentration.
Water is taken up by the plant's roots and transported up its circulatory system via xylem tissue.
As water enters the leaf and is absorbed by osmosis into the cells that create glucose and oxygen when combined with CO2. The vacuole inside the cell can store water.
Therefore, Transpiration pull model best shows the movement of water during photosynthesis.

Answer:
temperature and precipitation
Explanation:
The biome concept organizes large-scale ecological variation. Terrestrial biomes are distinguished primarily by their predominant vegetation, and are mainly determined by temperature and rainfall. Differences in temperature or precipitation determine the types of plants that grow in a given area (Figure 1).

Which choice best describes the relationship between biodiversity and invasive species?
a. As invasive species increase, it causes biodiversity to increase
b. As invasive species increase, it causes biodiversity to decrease
C. As biodiversity increases, it causes invasive species to increase
d. As biodiversity increases, it causes invasive species to decrease
Answer:
b. As invasive species increase, it causes biodiversity to decrease
Explanation:
Invasive species refers to those species of organisms that are foreign (non-native) to a particular environment or habitat with the tendency to outgrow and outcompete the native species in that habitat. Due to their fast reproductive and growth rate, they tend to diminish the population of native species by using up the available nutrients.
Biodiversity is the richness of organism species on Earth. When invasive species increase in a particular habitat or ecosystem, they cause the biodiversity in that habitat to decrease because they tend to take charge and dominate, causing harm to every other species. Hence, As INVASIVE SPECIES INCREASE, it causes BIODIVERSITY TO DECREASE

8. Los compuestos no metálicos hidrogenados que se encuentran en medio
acuoso se denominan:
Answer:
La respuesta correcta es "hidruros metálicos".
Explanation:
Los hidruros metálicos son compuestos formados a partir de dos elementos: metal e hidrógeno. Los metales que pueden encontrarse en estos compuestos son aquellos presentes en el grupo IA y IIA de la tabla periódica (excepto el berilio y el magnesio). Los metales de este tipo forman un solo hidruro dado que actúan con su menor valencia. Los hidruros metálicos son sólidos cristalinos que pueden ser disueltos en medios acuosos.

How does a decrease/decline in a top predator impact biodiversity in an ecosystem?
Answer:
The most obvious result of the removal of the top predators in an ecosystem is a population explosion in the prey species. ... When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other. When the predators are removed, prey populations explode.

Can you describe how a researcher might use naturalistic observation, case studies, and survey research to investigate gender differences in aggressive behavior at the workplace? First state a hypothesis, and then describe your research approaches. What positive and negative features does each method have? List three benefits of using animals in psychological research.
Answer:
The specification of the circumstance is characterized underneath in the interpretation category.
Explanation:
To continue investigating differences between men and women throughout the aggressive behavior of employees, a research scientist can use observation methods, research papers, or observational studies. The naturalistic observation was being used without people's awareness to classify the actions of persons throughout the natural world. In this, the researcher examines individuals for some violent actions and often examines gender disparities throughout this workplace climate with aggressive behavior.Throughout the case research, the researcher does a throughout-depth study on gender disparities mostly in current workplace violent behavior. Here also, not only would the researcher observe the behavior, and address questions about the gender gaps between the departments. The investigator focuses on collecting information about the number, spread, and interrelationships of gender disparities throughout the large population through survey studies.Hypothesis:
Research hypothesis (H1): There seems to be a correlation among both gender differences but instead aggressive performance in the workplace. Null hypothesis (H0): There seems to be no correlation regarding disparities in gender as well as violent work performance.Research approach:
Qualitative descriptive research design could be employed throughout the descriptive research. In all of this, more attention is put on gathering knowledge about prevalence as well as the interconnection of gender disparities with occupational violent behavior. In this, this same data will be gathered by face-to-face interviews, questionnaires on genetic factors, and occupational hostile behavior.

2. Given a force of 100 N and an acceleration of 10 m/s, what is the mass?
Given:
Show your work:
F = 280n
a=0.5 m/s2
m=i
Explanation:
This question is a bit unclear. I think it's two questions conjoined. Anyways,
F=m×a
F=100N
a=10m/s^2
m=?
Making m the subject of formula
m=F/a
Substituting we have,
m= 100/10
m=10kg
Using the formula for m above
F=280N
a= 0.5m/s^2
m=?
m=280/0.5
m=560kg
Let's check our answers
F=m×a
F=10kg×10m/s^2
F=100N
Correct✓
F=560kg ×0.5m/s^2
F=280N
Correct✓
