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 ? O 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 O The container that holds the liquid
Answers
Answer: the candy tablets being added
Explanation:
just took it
The candy tablets being added to the drink would be the catalyst of the reaction in the drink.
WHAT IS A CATALYST:
A catalyst is any substance that makes the rate of a chemical reaction faster by lowering the activation energy needed for the reaction to occur.Catalyst makes a reaction proceed faster than usual. In this case, a student who wants to make a liquid volcano notices bubbling in a sealed drink bottle. She then opens it and began to add candy tablets using a rolled piece of paper.She notices that a very powerful reaction occured as she constantly puts the candy tablets in the drink. This suggests that the catalyst of this reaction in the drink is the CANDY TABLETS.Learn more: brainly.com/question/1565029?referrer=searchResults

A students is planning an experiment to find out how the heights from which he drops a ball affects how high the ball bounces. The dependent variable is the _____________.
Answers
Answer:
height of the ball when it bounces
Explanation:
The dependent variable in the experiment would be the height attained by the bouncing ball after dropping it.
The dependent variable during research or an experiment is the actual variable being measured by the researcher. It is the variable whose value is dependent on other variables in an experiment.
In this case, the height at which the ball is dropped would determine the height reached by the ball as it bounces. Hence, the height at which the ball is dropped is referred to as the independent variable while the height reached when it bounces is the dependent variable.

There are various kinds of plants that grow in various climatic conditions. All these varieties require different conditions for their growth.
The conditions required for growth depend on the structure and chemical properties of the plants. The amount of sunlight, water and nutrition required differs in these physical and chemical and chemical properties.
The kind of soil required is also different according to the different kinds of plants. Soil availability depends on the geographical location. Therefore, to grow a particular kind of plant it's important to ensure that the soil required for its growth is available in that geographical location.
So, knowledge of all this is required to grow and maintain plants in a classroom.

Describe how cohesion and adhesion contribute to the upward movement of water through a plant.
Answers
Answer:
Cohesive forces makes molecules stick to become a mass. This force ensures that the water molecules stick together to form a mass. This enables water to fill the xylem which is a vascular bundle in plants.
Adhesion forces is what enables the water molecules which are now in form of a single mass to move upward in the columns of the cells for distribution of water and nutrients.

Dr. Benjamin Carson was a neurosurgeon that is currently the Secretary of Housing and Urban Development. The scientific method has been around a long time, so it does not make sense that it would be him.
Charles Darwin is famous for his evolution theory, not the scientific method.
Carl Linnaeus was the dude that came up with the idea of naming organisms, so this option is not correct.

recent studies in bone research indicate that using ultrasound on a broken bone can decrease the healng time by 25% which of these are the most basic levels of organization involved when a bone heals
Answers
Answer:
This question is incomplete, it lacks options. The options are:
A. Cells and tissue
B. Cells and organ system
C. Organ system and organism
D. Tissue and organ system
The answer is A. Cells and tissue
Explanation:
A fractured/broken bone is capable of healing with time, although the process can be time-consuming. What occurs during the process is that blood clots develop around the area of the broken bone in order to protect the fracture and supply cells needed for the repair of the broken bone.
The aggregation of these cells form a tissue, which is the repair substance needed for the joining of the broken fragments. This repair substance is called CALLUS, which is initially made up of cartilage but later changes into bone tissue.
Hence, the most basic levels of organization involved when a bone heals are the CELLS and TISSUES.

Human predators are drastically reducing population size. Humans' use of resources in general is greater than resource availability. There is no evidence that humans have reached carrying capacity. Humans have exhausted available space.
Answers
Answer
There is no evidence that human has reached carrying capacity.
Explanation:
It should be understood that carrying capacity is the situation whereby the person or organism involved can no longer perform its activity again. In other words, it means when someone or somebody has reached his/ her maximum capacity.
And in this case, it can not be said that human beings have reached their carrying capacity, this is because they are continually developing and making things that will keep on increasing their ability in terms of production to meet the continuous growth of their population.
