egg albumen protease dilute hydrochloric acidExplanation:
A protease is a kind of peptidase enzyme that breaks down proteins into peptide molecules. As a digestive enzyme it is located in the lining of the stomach where, relative to the hydrochloric acid in digestive juices, the pH is usually low/ acidic.
Enzymes speed up reaction rates by providing alternative pathways. By modifying the enzyme composition, supplying more collision energy, and changing the collisions between and the ratio of reactants, certain variables will increase the reaction rate.
Proteases function well at 37℃, the typical internal temperature of the human body- this temperature provides adequate energy for the reaction. Similarly, proteases require low pH for the correct configuration, and beyond this pH and temperature, they may become denatured or simply not function well as catalysts.

Some people can roll the tongue into a tube shape, while others cannot. Practicing is not likely to help because tongue-rolling is an inherited trait. The allele for rolling the tongue (R) is dominant to the allele for not being able to roll the tongue (r).
Create a Punnett square. Make sure that it shows a cross between two parents with at least one R allele.
Answers
Hope this helps :)
The Punnett square, showing a cross between two parents with at least one R (rolling the tongue) allele, is mentioned below.
What is a Punnet square?A Punnett square is a graphical tool used by geneticists to predict the probability of offspring genotypes resulting from a cross between two parents with known genotypes.
In the Punnett square, the uppercase R represents the dominant allele for tongue rolling, and the lowercase r represents the recessive allele for not being able to roll the tongue.
The possible offspring genotypes are shown in the boxes within the table. The ratio of genotypes is 1:2:1, with 25% of the offspring having the homozygous dominant genotype (RR), 50% having the heterozygous genotype (Rr), and 25% having the homozygous recessive genotype (rr).

Lactase is an enzyme produced by many organisms. It is located in the brush border of the small intestine of humans and other mammals. Lactase is essential to the complete digestion of whole milk; it breaks down lactose, a sugar which gives milk its sweetness.
In Figure 7-2, which picture shows weathering that involves carbonic acid: A, B, or C?
Answers
Answer: C
Explanation: Carbonic acid is the culprit when it comes to the carbonation type of chemical weathering. As rain goes through the air and into the ground, it grabs carbon dioxide, creating carbonic acid. This weak acid reacts with the calcium carbonate in stones when it seeps into the cracks.

mutualism-commensalism-parasitism.
Explanation:
There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism. Mutualism: both partners benefit. ... Commensalism: only one species benefits while the other is neither helped nor harmed.
Mutualism: both partners benefit. An example of mutualism is the relationship between the Egyptian plover and the crocodile. ...
Commensalism: only one species benefits while the other is neither helped nor harmed. ...
Parasitism: One organism (the parasite) gains, while the other (the host) suffers.
Benifited and harmed :-Mutualism is a symbiotic relationship in which both species benefit. Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed.

12. Scientists may design an experiment with a control group, which is a set of organisms or sam-

can then compare normal changes in organisms or samples with those that may have occurred
because of the treatment. The idea of a control group is not the same as a controlled variable.
Suppose a scientist is doing an experiment to determine the effect of an all-organic diet on the
occurrence of cancer in rats.
a. What variables should the scientist control in the experiment?
b. Describe the control group for this experiment.
Answers
Answer:
a) same species of rats
b) Some rats will not be given the all-organic diet
Explanation:
In an experiment, a control group is the group that do not receive the treatment (the independent variable) that is being tested while the control variables or constants are the variables that must be kept constant throughout the course of the experiment in order not to alter the experiment's outcome.
In this experiment where a scientist is trying to determine the effect of an all-organic diet on the occurrence of cancer in rats, the control group would be the GROUP OF RAT THAT DO NOT RECEIVE THE ORGANIC DIET. Also, a control variable would be the SAME SPECIES OF RAT USED throughout the experiment.

Answers
Answer:

Explanation:
The area that had never had a road is extremely useful because it acts as the control group in the experiment. The researchers can use this untouched area of land as a benchmark for the rest of the experiment. Once they implement both test scenarios on the pieces of road, they can then compare the results gathered from each study with the data gathered from the area that had never been a road in order to determine which option provides results that best compare to the original properties of the piece of area that has never been made into a road.
