Answer:
Enzymes can only be used once
Explanation:
Enzymes are there forever
Enzymes are the bio-catalysts that play a crucial role in several chemical reactions and metabolic cycles of the body.
The statement for the enzyme that is false is:
Option D. Enzymes can only be used once
The role of enzymes are:
1. The enzymes are the protein molecules, which are made up of long chains of amino acid residues.
2. Enzymes are highly specific because they have different shaped active sites for the binding of respective substrates.
3. Enzymes are the important parts of reactions and are the bio-catalysts. They lower the activation energy for the reactions and fasten the rate of reaction.
4. The enzymes are referred to as catalysts, and thus they are not utilized in the reaction, thus, they can be reused again.
Thus, Option D is false for enzymes.

Which of the following refers to a physical trait, such as color, size, or odor? A. experimental group B. qualitative trait C. quantitative trait D. control group
Answer:
B Qualitative
Explanation:
color, size and smell are all qualities of the organism
Type of data that is in the form of a description; example: color of the water
Answer:
The correct answer is - qualitative data.
Explanation:
Qualitative data are the consequence of arranging or explaining traits of a object, population or other things. qualitative data are additionally often called as categorical data.
Example of qualitative data is color of water, blood type, ethnic gathering, the vehicle an individual drives, and the road an individual lives on are instances of qualitative(categorical) information.
Thus, the correct answer is - qualitative data.

Based on the graph, at what temperature does this enzyme work best? * Captionless Image 47 C 30 C 40 C 15 C
The enzyme works best at optimum temperature. They will best at 37 degree celcius.
What is the optimum temperature?Enzymes function best between 20 and 35 °C. At very low temperatures, they become inactive, and at very high temperatures, higher than 45°C, they get denatured, or destroyed.
A greater rate of collisions between enzymes and substrates may result from increased molecular activity brought on by temperature increases.
However, if the temperature increases too much, the enzymes may become denatured and the beneficial benefits of the temperature increase may be reversed.
Therefore, The enzyme works best at optimum temperature. They will best at 37 degree celcius.

What type of bond is formed when two atoms share a pair of electrons?
The change in allele frequencies that occur due to the colonization of a new location by a small group of individuals is called
Answer:
Founder effect.
Explanation:
The founder effect is a case of genetic drift in which a small population sample of a limited number of individuals is shed from a larger population, its gene pool carrying only a part of the genetic diversity represented in the source population. Thus, it is likely that the genetic destinies of the population of origin and of the new population are established in different ways. When a new generation has randomly distributed alleles, with a large enough sample size, we can expect that the gene pool of the new generation will more or less represent the gene pool of the previous generation.

Water has the ability to moderate temperature.
Water is a versatile solvent.
Water displays cohesive behavior.
Answer: A, B, C, D
I am pretty sure it is all of them.
Explanation:
I say this because when molecules freeze they stop moving as fast. And then waters like oceans can monitor their tempurature by storing and realesing heat from the sun. Also water is a solvent because it breaks apart most subsentces. The solvent one I am not so sure about because it does not break down everything but idk. And also it can be cohesive, that is how water can stay on top of a glass. I hope I am not wrong and i hope this helps! :)

Calculate to average diameter for each bubble solution. Super bubble=____cm regular bubble soap____cm
Use the results on the chart
The average diameter of superbubbles is 15.1 cm and the average diameter of regular soap bubbles is 11.5.
What is meant by average value?
The mean obtained by obtaining the ratio of the sum of total values in a set of data and the total number of values in a given data is called the average of the data.
The formula for average had several applications. The average number of people suffering from a disease can help in the study of the disease.
The average is calculated by finding the sum of numbers and dividing it by the total values of numbers.
Thus
The average diameter of superbubbles =
[tex]\frac{15+10+12+18+22+13+16+18+15+12 }{10} = 15.1[/tex]
The average diameter of regular bubbles =
[tex]\frac{10+5+16+11+12+11+15+15+6}{10} =11.5[/tex]
Therefore, the average diameter of superbubbles is greater than the average diameter of regular bubbles.

Carlos noticed a large population of anoles in the park across from his school. The anoles are a variety of colors and sizes. Carlos decided to measure the anoles. He believed that the brighter colored anoles are smaller than the darker colored anoles. His results are below:
Answer:
This question is incomplete; the missing fragment of the question is:
The results are as follows:
12.9 neon, 13.8 neon, 13.9 dark, 14.2 brown, 14.2 blue, 15.5 neon, 15.6 gray, 15.8 gray, 16.1 blue
Did Carlos' data support his hypothesis?
The answer is NO
Explanation:
According to the question, Carlos observed a large population of anoles, which are a variety of colors and sizes in the park across from his school. He then decided to measure the anoles.
However, he hypothesized that: the brighter colored anoles are smaller than the darker colored anoles. In his results, he measured the following sizes for each color of anole:
12.9 neon, 13.8 neon, 13.9 dark, 14.2 brown, 14.2 blue, 15.5 neon, 15.6 gray, 15.8 gray, 16.1 blue
Based on this data, the hypothesis IS NOT SUPPORTED BY THE DATA. This is because the measurements contained same color of anoles that varied in size. If his hypothesis were correct, anoles of the same color should have the same size when measured.
Which organelle is responsible for packaging and sending out proteins to their proper destinations? Choose 1 answer: (Choice A) A Mitochondria (Choice B) B Golgi body (Choice C) C Nucleus (Choice D) D Lysosome
Answer:
(Choice B) Golgi Body
Explanation:
The rough endoplasmic reticulum works with the Golgi apparatus to move new proteins to their proper destinations in the cell.
The Golgi body is in charge of storing proteins from the rough endoplasmic reticulum in membrane-bound vesicles, which are small lipid bilayer storage units that move molecules to the cell membrane, hence option B is correct.
What is the Golgi body?In all eukaryotic cells, the cytoplasm a gel-like fluid retained in the cell membrane contains a stack of membranes that make up the Golgi apparatus (i.e., complex cells).
Camillo Golgi, who discovered a reticular structure in the cytoplasm of several cell types using silver chromate staining, gave the Golgi apparatus (also known as Golgi to its admirers), its first official name in 1888.
Therefore, the nucleus and rough endoplasmic reticulum are frequently located nearby, an organelle involved in protein synthesis, hence option B is correct.

The four levels of protein structure are the
primary, secondary, tertiary, and quaternary structures.Primary structure: The Primary structure is the basic sequence of amino acids that form a polypeptide chain. There are basically 20 amino acids in a protein.
Secondary structure: This is the regular pattern of folding in the basic structure of a protein. The foldings occur as the alpha and beta sheets.
Tertiary structure: This is the 3 dimensional folding of the polypeptide chain as found in most enzymes.
Quaternary structure: This protein structure is formed from two or more polypeptide chains. The hemoglobin molecule is an example.
