"A testcross involves an individual exhibiting the dominant phenotype but an unknown genotype being crossed with an individual that has a(n) ___________ genotype."
Answer:
The correct answer is - h(omo)zygous recessive
Explanation:
When a cross between the organism with dominant phenotype, that can be heterozygous genotype or h(omo)zygous genotype, with a organism of h(omo)zygous recessive takes place, the cross known as test cross.
Test cross always exhibit an individual with the dominant phenotype. he aim of test cross is to find if the dominant individual is h(omo)zygous or heterozygous.
Thus, the correct answer is - h(omo)zygous recessive.

Carbon is transferred from the
atmosphere to organisms through
Answer:
photosynthesis process
Explanation:
carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide. Through the process of photosynthesis process, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.
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.

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.

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

What are proteins?A protein is a found naturally, a highly complicated substance made up of amino acid residues linked together by peptide bonds.
Proteins are found in all living organisms and contain a variety of important biologically active compounds such as enzymatic reactions, hormones, and immunoglobulin.
Proteins are massive complex molecules that perform numerous important functions in the body.
They are essential for the structure, operation, and regulatory oversight of the body's tissues and organs and do the majority of the work in cells.
