Question 6(Multiple Choice Worth 3 points)
(04.01 MC)

Starting with the European settlers, humans have introduced earthworms from Europe and Asia into North American forests. These introductions continue through the transport of soil that contains non-native earthworms, such as during construction and through the release of non-native earthworms used for fishing. The effects of non-native earthworms are especially large in forests that did not have any native earthworms. For example, forests of the Great Lakes region did not previously have earthworms until humans introduced them. When non-native earthworms are introduced, the thick layer of leaves, known as leaf litter, covering the ground disappears quickly, thereby altering biogeochemical cycles.

Which of the following correctly traces a nutrient pathway in a Great Lakes forest that is invaded with non-native earthworms?


trees → leaf litter → earthworm → atmosphere
leaf litter → earthworm → soil → trees
bird → earthworm → soil → trees
earthworm → fungi → leaf litter → trees

Answers

Answer 1

The correct trace nutrient pathway in a Great Lakes forest that is invaded with non-native earthworms is leaf litter → earthworm → soil → trees. The correct option is B.

What is a nutrient pathway?

When there is an oversupply of food, nutrient-sensing pathways activate anabolism and storage, and when there is a shortage of food, homeostatic mechanisms including the mobilization of internal stores via mechanisms like autophagy are triggered.

Human metabolic illnesses frequently exhibit altered nutrient-sensing mechanisms.

Therefore, the correct option is B, leaf litter → earthworm → soil → trees.

What is Evolution?

This is referred to as the change in the heritable characteristics of biological populations over successive generations.

All an organism's characteristics can be inherited and evolves over a period of time as a result of the changing environmental conditions which helps them to adjust thereby increasing their chances of survival hence preventing extinction of species.

For example, over millions of years of evolution, many horses lost their side toes and developed a single hoof as a result of them needing to move at faster speeds to evade predators.

Answers

9 of the offsprings will be dominant for both traits in the above dihybrid cross.

What is a dihybrid cross?

A dihybrid cross is a cross between two individuals with two observed traits that are controlled by two distinct genes.

Gregor Johann Mendel known as the father of genetics was the first person to discover the basic principles of heredity during the mid-19th century.

In a dihybrid cross between two parents that are heterozygous for both traits, the cross will result in four different combinations of seeds in the F2 generation as follows:

Justify the researcher analyzing blood samples at many intermediate time points instead of at only the beginning and the end of the 20-week period.

Answers

Answer:

The dependent variable measured in the researcher’s experiment is the concentration of the drug in the blood samples. One control that the researcher could use to improve the validity of the experiment is to ensure that the same amount of the drug is administered to each participant.

Analyzing blood samples at many intermediate time points instead of at only the beginning and the end of the 20-week period allows the researcher to track changes in the concentration of the drug over time.

What is the answer for Tia makes a model of a glacier with clay, sand, and an ice cube. She pushes the ice cube over the clay that is covered with sand. Explain how she could use the model to show that glaciers carry soil.

Answers

The model prepared by Tia could be used to show the glaciers which carry soil as similar to the clay which carries the ice cubes and sand, the glaciers also carry various materials along with them.

What are Glaciers?

A glacier is a persistent body of dense ice and other materials that is constantly moving under its own weight and force. A glacier forms where the accumulation of snow exceeds the ablation over the period of many years, often centuries.

Glaciers acquire the distinguishing features, such as crevasses and seracs, as it slowly undergoes flow and deforms under the stresses which are induced by its own weight. As it moves constantly, it abrades rocks and debris from its substrate to create the major landforms such as cirques, moraines, or fjords. Although a glacier may flow into a waterbody, it forms only on the land surface and is distinct from that of much thinner sea ice and lake ice which form on the surface of bodies of water.

The similarity between parthenogenesis and sexual reproduction is “Parthenogenesis involves the formation of a zygote”

How is parthenogenesis similar to sexual reproduction?

This method is alike to the fusion of an egg and sperm in sexual reproduction since it shapes a diploid nucleus from the fusion of two dissimilar cells. The resulting offspring is a homozygote and gets about half of its mother's genetic disparity. This type of parthenogenesis could make either a female or a male.

Many years ago, scientists
considered sponges to belong to Kingdom Plantae. What sort of evidence convinced them that sponges belonged to Kingdom Animalia?

Answers

Sponges were originally classified as plants because they were immobile and seemed to lack the basic animal characteristics of muscles and nerves. However, in the 1820s, scientists began to question this classification and discovered that sponges possess certain characteristics that are more characteristic of animals. For example, sponges have cells called choanocytes, which have flagella and are responsible for creating water currents within the sponge. These cells are similar to the collar cells found in the simplest animals, known as choanoflagellates. In addition, sponges have cells called amoebocytes that can move and digest food, which are characteristics of animal cells. These and other discoveries led scientists to reclassify sponges as animals and place them in the kingdom Animalia.

B. Should the cleaner be taken off the market
C. Are there safer chemicals that could be used in the cleaner?
D.are there other possible causes of cancer?

Answers

D. are there other possible causes of cancer?

Scientific argumentation involves testing hypotheses through rigorous experimentation and examination of evidence. In this case, before drawing any conclusions about the relationship between the chemical in the household cleaner and cancer, other scientists would want to examine whether there are other possible causes of cancer that should be considered. The scientist who made the claim would need to show through experiments and studies that the chemical in question is the cause of cancer and not some other variable that was not controlled in the study. And therefore, evaluating the evidence and testing the hypothesis is the fundamental part of scientific argumentation.

Answer:

C wind erosion is most responsible for the formation of sand dunes.

Explanation:

Sand dunes are formed when wind blows loose sand from a beach, desert, or other location, and deposits it in a new location. The sand is then shaped by the wind into dunes, which can vary in size and shape depending on the strength and direction of the wind. Water erosion, volcanism, and glaciation can all also contribute to the formation of sand dunes to some extent, but wind erosion is typically the primary process responsible for their formation.
