Which category of environmental worldview do you think would be most likely to lead to a sustainable future if it were widely accepted and why
Answer:
There are three major types of environmental worldviews: anthropocentric (human-centered), biocentric (life-centered), or ecocentric (earth-centered).
Explanation:
Sustainable development is the only way to protect natural resources for future generations.
What is sustainable development?Sustainable development is an overarching theme for achieving human development goals while also preserving natural systems' ability to provide the natural ecosystem services and resources on which the economy and society rely.
Sustainable development is the sole way to preserve natural resources for future generations because development takes place but without causing harm to natural resources or the environment.
The United Nations adopted the Sustainable Development Goals (SDGs), also known as the Global Goals, in 2015 as a universal call to action to end poverty, safeguard the environment, and make sure that in future, all people enjoy peace and prosperity.
Thus, the category of environmental worldview do you think would be most likely to lead to a sustainable future if it were widely accepted is sustainable development.

Based on the literature, you hypothesize that students in traditional biology lectures will have the same grades as students in online biology lectures. You decide to test your hypothesis by comparing grades of students in traditional and online biology lectures over a semester. As a result of the experiment, you observe that the grades in the traditional lectures and the grades in the online lectures are not significantly different. What do these observations allow you to do
Answer:
See the answer below
Explanation:
The observation allows one to make a conclusion based on the hypothesis.
From the observation that the grades in the traditional lectures are significantly different from the grades in the online lectures, the hypothesis that students in traditional biology lectures will have the same grades as students in online biology lectures would be rejected.
The observation of the significant difference, thus, helps to reject the initial hypothesis, also known as the null hypothesis.

Which of the following is an example of an enzyme?
Carbohydrates
O Proteins
O Lipids
O Nucleic acids
Answer -proteins
Any of a set of enzymes that divide proteins into shorter pieces (peptides), and subsequently into their constituent amino acids, is known as a proteolytic enzyme. Thus, option B is correct.
What is role of enzymes as a protein?Enzymes are proteins that interact with substrate molecules to stabilize the transition state and lower the activation energy required for a chemical reaction to occur.
Through stability, reaction rates accelerate and reach physiologically important rates.
Proteins called enzymes are made up of amino acids connected by one or more polypeptide chains.
The fundamental structure of a polypeptide chain refers to this arrangement of amino acids. The three-dimensional structure of the enzyme, including the geometry of the active site, is then determined by this.
Therefore, Proteins are an example of an enzyme.

What's the independent variable? What's the dependent variable? How many bacteria were found at 30 degrees? How many bacteria were found at 15 degrees? How many more bacteria were found at 20 degrees than 10 degrees? How many more bacteria were found at 35 degrees than 0 degrees?
Answer: Temperature is the independent variable. The number of bacteria is the dependent variable.
Explanation:
The dependent and independent variables are the two main variables of any experiment or research.
A dependent variable is one whose values depend on another variable. In a function it is usually represented by 'y'. This variable 'y' is a function of the variable 'x', which is the independent variable. An independent variable is one whose value does not depend on that of another variable.
So, the independent variable is the one that changes or is controlled to study its effects on the dependent variable. The dependent is the variable that is investigated and measured.
The independent variable is represented on the x-axis (horizontal line) of a graph, while the dependent variable is represented on the y-axis (vertical line).
In your example, the temperature is the independent variable, because it does not depend on anything and its influence can affect the number of bacteria. And it can be changed or controlled by the scientists. The number of bacteria is the dependent variable, because it depends on the temperature. Also, the number of bacteria is what it is being measured, and can not be changed by the scientists.
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?
1.)
2.)The candy tablets being added to the drink. The gasses being released when the drink was first opened.
3.)The piece of paper being placed over the soft drink. The container that holds the liquid.
Answer:
candy tablets being added
Explanation:
The candy tablets being added to the drink would be the catalyst.
WHAT IS A CATALYST:
A catalyst is a substance that speeds up the rate of a chemical reaction. This is done by lowering the energy needed for the reaction to kickstart called activation energy.Catalyst makes chemical reactions 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: https://brainly.com/question/1565029?referrer=searchResults

Answer:
The correct answer is CCAM or Congenital Cystic Adenomatoid Malformation.
Explanation:
A benign lesion in the lungs, which originates before birth in the form of a mass or cyst in the chest is termed as CCAM or Congenital Cystic Adenomatoid Malformation. It is formed of an unusual lung tissue, which does not work appropriately, however, it continues to develop. CCAM is also known as CPAM or congenital pulmonary airway malformation.
It is a common fetal lung lesion. It originates before the birth of the baby, and can differ in size and can be either solid or filled with fluid. A small cyst or solid appearing lesion is known as microcystic, and a large cyst is termed as a macrocytic lesion. Most of the CCAM lesions are so small that they do not result in any kind of issues to the baby at the time of pregnancy and can be taken out after birth. However, some CCAMs can be dangerous if not diagnosed and treated earlier.
