From smallest to largest, the levels are species, genus, family, order, class, phylum, and kingdom. Each of the ranking levels is called a taxon. Just as a genus is a group of similar species, a family is a group of similar genera. An order is a group of similar families.

In Figure 7-2, which picture shows weathering that involves carbonic acid: A, B, or C?
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.

After reading the paragraph below, answer the question that follows.Scientists interested in knowing the best way to restore an area after a temporary road was built through it completed a study comparing two treatments: (1) restoring the contour of an area so that there was no longer a depression or cut-through where the road was previously and (2) simply abandoning the area to allow vegetation to return on its own. They wanted to know whether either or both of these treatments would return the aboveground vegetation and the belowground soil properties to their original state, as seen in a similar area where there had never been a road.In this experiment, the area that had never had a road is useful to the experiment because:________________
Answer:
it acts as the control group in the experiment
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.

Explain the 3 types of symbiosis. Give examples of each and explain which organism is benefited, harmed or is neutral to the relationship.
Answer:
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.

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.
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).

D. They are inorganic molecules that all contain carbon.
Answer:
A. They are organic molecules that all contain carbon.
Explanation:
All known life on earth is carbon-based. Most molecules used as building blocks are organic i.e. consisting of based on carbon. This means that they consist of atoms of carbon, hydrogen, oxygen with other variations like nitrogen.
Some macromolecules include glucose-based polysaccharides, amino-acid based proteins and lipids consisting of glycerol and fatty acids.

What is the role of lactase? which sugar does the act on in reaction?
Answer:
This enzyme helps to digest lactose, a sugar found in milk and other dairy products. Lactase is produced by cells that line the walls of the small intestine. ... Lactase functions at the brush border to break down lactose into smaller sugars called glucose and galactose for absorption.
Explanation:
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.
Extension Questions
12. Scientists may design an experiment with a control group, which is a set of organisms or sam-
ples that do not receive the treatment (the independent variable) that is being tested. Scientists
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.
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.
