According to this image, as light intensity increases, the rate of photosynthesis...
Correct Answer
A. Increases
Explanation
The image shows a graph with light intensity on the x-axis and the rate of photosynthesis on the y-axis. As the light intensity increases, the rate of photosynthesis also increases. This can be seen from the upward trend of the graph. Therefore, the correct answer is "Increases".
2.
According to this image, as temperature increases, the rate of respiration...
Correct Answer
D. Not answered by this grapH
Explanation
The image does not provide any information or data about the rate of respiration as temperature increases. Therefore, we cannot determine the effect of temperature on the rate of respiration based on this graph.

This kingdom consists of prokaryotic cells commonly found in a classroom.
Correct Answer
C. Eubacteria
Explanation
The correct answer is Eubacteria because prokaryotic cells are typically found in this kingdom. Eubacteria are single-celled organisms that lack a nucleus and other membrane-bound organelles. They are commonly found in various environments, including classrooms. Archaea are also prokaryotes, but they are typically found in extreme environments. Protists are eukaryotic organisms, while fungi are a separate kingdom of eukaryotes. Therefore, Eubacteria is the most appropriate choice based on the given information.
4.
This kingdom consists of heterotrophic organisms with a cell wall, commonly decomposers.
Correct Answer
D. Fungi
Explanation
Fungi is the correct answer because fungi are heterotrophic organisms that have a cell wall. They obtain their nutrients by decomposing organic matter, making them common decomposers. This kingdom includes organisms such as mushrooms, molds, and yeasts.
5.
This kingdom consists of heterotrophic organisms lacking a cell wall.
Correct Answer
E. Animals
Explanation
Animals are the correct answer because they are heterotrophic organisms that lack a cell wall. Unlike plants and fungi, animals do not have a rigid cell wall made of cellulose or chitin. Instead, they have flexible cell membranes that allow for movement and interaction with their environment. Animals obtain their nutrients by consuming other organisms or organic matter, making them heterotrophs. This distinguishes them from autotrophic organisms like plants and algae, which can produce their own food through photosynthesis.
6.
This term describes organisms capable of obtaining (and storing) energy from inorganic sources (such as water and carbon dioxide and light).
Correct Answer
B. AutotropH
Explanation
Autotrophs are organisms that can produce their own food using inorganic sources such as water, carbon dioxide, and light. They are capable of converting these sources into energy through processes like photosynthesis. Unlike heterotrophs, which rely on consuming organic matter for energy, autotrophs have the ability to store and utilize energy from inorganic sources. This allows them to sustain themselves and play a vital role in the food chain by providing energy for other organisms.

A Purple, Tall pea plant (AaBb) is crossed with another Purple, Tall pea plant (AaBb). Out of sixteen offspring, how many would you expect to be Purple, dwarf?
Correct Answer
B. 3
Explanation
In this question, the parents are both heterozygous for the purple and tall traits (AaBb). When these parents are crossed, the possible combinations of alleles in the offspring are AB, Ab, aB, and ab. Out of these combinations, only Ab and aB would result in a purple, dwarf phenotype. Since there are two possible combinations that would result in the desired phenotype, we can expect 2 out of the 16 offspring to be purple, dwarf. Therefore, the correct answer is 3.
8.
A Purple, Tall pea plant (AaBb) is crossed with another Purple, Tall pea plant (AaBb). Out of sixteen offspring, how many would you expect to be Purple, Tall?
Correct Answer
D. 9
Explanation
When two plants with the genotype AaBb are crossed, there are four possible combinations of alleles in the offspring: AB, Ab, aB, and ab. Each combination has an equal chance of occurring, so there is a 1/4 probability of each. Out of the sixteen offspring, 1/4 of them would have the genotype AaBb, which represents being purple and tall. Therefore, we would expect 1/4 of sixteen, which is 4, to be purple and tall.
9.
Which of the following represents a recessive genotype?
Correct Answer
E. Aa
Explanation
The recessive genotype is represented by "aa". In genetics, a recessive genotype refers to a pair of alleles where the trait associated with that allele is only expressed when both alleles in the pair are the same. In this case, the lowercase "a" represents the recessive allele, and since both alleles are "a" in "aa", it indicates a recessive genotype.

Red/green color-blindness is a recessive, sex-linked trait. A woman is a carrier and her husband is not color-blind. What percent of the sons will be color-blind? What percentage of their daughters will be color-blind?
Correct Answer
B. 50%; 0%
Explanation
Since red/green color-blindness is a recessive, sex-linked trait, the woman being a carrier means that she has one normal allele and one color-blind allele. The husband, being not color-blind, has two normal alleles. When they have children, there is a 50% chance that a son will inherit the color-blind allele from the mother and be color-blind. However, since daughters inherit one normal allele from the father and one normal allele from the mother, they will not be color-blind. Therefore, the percent of sons that will be color-blind is 50% and the percentage of daughters that will be color-blind is 0%.

Most corn being planted in South Dakota is transgenic, meaning ....
Correct Answer
C. It has genes from more than one organism
Explanation
The correct answer is "It has genes from more than one organism." This means that the corn being planted in South Dakota has been genetically modified to contain genes from multiple organisms. This genetic modification is done to introduce desirable traits into the corn, such as resistance to pests or tolerance to herbicides. By incorporating genes from different organisms, scientists can enhance the characteristics of the corn and improve its overall performance.

According to this cladogram, lampreys ....
Correct Answer
C. Are vertebrates but lack jaws, fingers and toes
Explanation
According to the cladogram, lampreys are vertebrates but lack jaws, fingers, and toes. This means that lampreys have a backbone and are classified as vertebrates, but they do not possess jaws, fingers, or toes like other vertebrates such as mammals or reptiles.
13.
According to this cladogram,
Correct Answer
A. Lungfish are more closely related to ampHibians than sharks.
Explanation
The cladogram is a diagram that shows the evolutionary relationships among different species. In this case, the cladogram suggests that lungfish and amphibians share a more recent common ancestor than lungfish and sharks. This means that lungfish and amphibians are more closely related to each other than lungfish and sharks. The cladogram does not provide any information about land vertebrates sharing traits with lungfish or about the common ancestors of sharks and bony fish. Additionally, the cladogram does not indicate how many times bony ribs evolved in Earth's history.

The purpose of respiration is ...
Correct Answer
C. Release energy stored in food
Explanation
Respiration involves oxygen and breathing, but we need these things to release the energy stored in our food (simple form = glucose).
15.
Which of these organisms undergo respiration?
Correct Answer
E. Animals, Fungi and Plants
Explanation
Respiration releases energy from food (sugar). If plants didn't undergo respiration, they couldn't use the sugar they make. Remember bean seed in respiration lab!
