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
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.

Answers
Herbivorous plants are plants that obtain their nutrients by consuming animals or animal products, rather than by photosynthesis. These plants can be divided into three main categories: carnivorous plants, which capture and digest insects and other small animals; omnivorous plants, which obtain nutrients from both animal and plant material; and parasites, which obtain nutrients by attaching themselves to a host plant or animal and extracting nutrients from it. Some examples of herbivorous plants include Venus flytraps, pitcher plants, and the Western Australian Christmas tree

Identify the type of macromolecule (carbohydrate, lipid, nucleic acid,
protein) that changes when Glu changes to Asp. Explain your answer.
Answers
Answer: The type of macromolecule that changes when Glu changes to Asp is a protein.
Explanation: The type of macromolecule that changes when Glu changes to Asp is a protein. This is because proteins are made up of long chains of amino acids, which are the building blocks of proteins. Glu and Asp are both amino acids, and they can be incorporated into a protein chain during protein synthesis. When Glu changes to Asp, it means that one of the amino acids in the protein chain has been replaced by a different amino acid. This can potentially alter the structure and function of the protein, depending on the specific role that the amino acid plays within the protein.

Is mass measured by Pan balance?Two pans are located on either side of a lever in the pan balancing scale. To achieve balance and determine the weight of the other thing, weights are placed on one side of the object and on the other side. Typically, the mass is expressed in grammes or kilogrammes.
Because of its practicality and accuracy, comparative weighing is frequently used to compare two things' masses rather than their absolute values. When preparing reagents and stock solutions, a top pan balance is typically used for rough weighing because minor weight differences do not significantly affect the outcome of analysis.

is there an impact on the environment if blue whales went extinct? Who or what would it impact?
Answers
Without whales, krill would probably consume a large portion of the free-floating phytoplankton on the ocean's surface, accelerating climate change noticeably.
What makes the blue whale significant in terms of the environment?
Although blue whales have a huge food need, the ocean environment benefits from them rather than being burdened by them. Their iron-rich excrement is a crucial supply of nutrients for the marine food web, boosting production in the Southern Ocean and increasing fisheries yields.
What impact does blue whale extinction have on biodiversity?
The food source for many animals in the marine ecosystem is the carcasses of whales. The disappearance of whales would deprive other marine species of nutrients, which will have an impact on all species in the ocean.

A.
violet flowers = 0.55, white flowers = 0.45
B.
violet flowers = 0.62, white flowers = 0.38
C.
violet flowers = 0.3, white flowers = 0.7
D.
violet flowers = 0.49, white flowers = 0.61
Answers
The allelic frequency of each type of flower is violet flowers = 0.3, white flowers = 0.7, option C.
What is allelic frequency?The incidence of a gene variant in a population is represented by the allele frequency. The number of times the allele of interest is observed in a population is divided by the total number of copies of all the alleles at that particular genetic locus in the population to calculate the allele frequency and can be expressed as a decimal, a percentage, or a fraction.
To find the allele frequency:
Frequency = 98/200 = p = 0.49 for white (v) flowers
VV - dominant homozygote with violet flowers and with frequency p²
Vv - heterozygote with violet flowers and with frequency 2pq
vv - recessive homozygote with white flowers and with frequency q²
q² = 0.49 = √q² = √0.49 = 0.7
Therefore q in the formula p + q = 1, = p + 0.7 = 1
p = 1 - 0.7 = 0.3
The frequency for violet flowers, p is 0.3 and white flowers, q is 0.7 with substitution method of the "p + q = 1, p2 + 2pq + q2 = 1" formula.

Briefly, explain how Tiktaalik could have existed in this Canadian environment.
Answers
Tiktaalik, an extinct fish species, could have existed in a Canadian environment due to the presence of shallow freshwater environments with low oxygen levels, which would have been suitable for its lung-like structure and ability to breathe air.
What is Tiktaalik?Tiktaalik is an extinct genus of fish that lived about 385 million years ago during the Late Devonian period. It is considered a transitional fossil, as it has characteristics of both fish and early tetrapods, four-legged land-dwelling animals. Tiktaalik could have existed in a Canadian environment, as it is known to have been found in the Canadian Arctic, specifically in the Elpistostege watsoni fossil beds of the Nunavut territory.
The environment during Late Devonian period in this region was a shallow freshwater delta or coastal plain that was home to a diverse array of fish and other aquatic organisms. Tiktaalik likely lived in the shallow water, and had adaptations such as flexible neck and fins with bones that resemble the limb bones of four-legged animals, which would have allowed it to move in shallow water and on land.

Match the phase described

The cell cycle can be explained as a sequence of events by which a cell duplicates its genome, synthesizes other cell constituents, and eventually divides into two daughter cells.
explanation
The two primary phases of the cell cycle are
1. The interphase It is the phase between two successive M phases. It follows cytokinesis. It is divided into G1, S, and G2 phases.The DNA replication occurs in the S phase of the interphase2. The M phaseThe M phase has four stages
ProphaseMetaphaseAnaphaseTelophaseCytokinesis follows the M phase.
The prophase is the first stage of the M phase. Here, the initiation of condensation of chromosome material takes place. As a result of this, the mitotic spindle is developed. The metaphase is characterized by the complete disintegration of the nuclear envelope. And, the chromosomes move to the spindle equator. In anaphase, two daughter chromatids are formed from the chromosomes. Telophase is characterized by the decondensation of the chromosome material and the formation of two new nuclei (Karyokinesis) and as a result, the mitotic spindle disappearsThe cytokinesis is the last step. Here, the cell gets divided into two daughter cells. In animal cells, it can be achieved by the appearance of a deep furrow in the plasma membrane. However, plant cells require a cell plate as they are enclosed by a cell wall.ConclusionSo, the final answers are,
Interphase - Replication of DNA and follows the cytokinesis.Prophase - Formation of the mitotic spindleTelophase - Mitotic spindle disappears as two new sets of chromosomes arrive at the opposite poles.Cytokinesis - The cell is split into two daughter cells and plants require the formation of a cell plate.why the birds fly on v-formation

Answers
Ionic bonds are preferred as they are stronger than covalent bonds.
Why Ionic bonds are stronger than covalent bonds?Ionic bonds result in a stable composite when all of the electrons between the components are transferred. While two elements only share electrons to form a stable molecule in a covalent bond.
Electrostatic force and Van Der Waals force are the forces that keep ions together and covalently linked elements together, respectively.
Cations and anions are created as a result of the complete transfer of electrons in ionic connections. As a result, these ions are attracted to one another strongly by electrostatic forces.
The Van Der Waal's force that exists between two covalently bonded elements is weaker than the electrostatic force because covalently bonded components only share electrons.

the blank determines which traits are adaptive during the process of natural selection
Answers
The environment determines which traits are adaptive during the process of natural selection.
What is natural selection?Natural selection is the process by which certain traits become more or less common in a population over time based on their effect on the survival and reproduction of the individuals that possess them. The individuals with traits that are better suited to their environment are more likely to survive and reproduce, passing those traits on to their offspring. Over time, this can lead to the evolution of species, as certain traits become more common in the population.
Natural selection is one of the main mechanisms of evolution and is often referred to as "survival of the fittest," although the term "fitness" in this context refers to how well an organism can survive and reproduce in its specific environment, rather than its physical strength or athleticism. Charles Darwin and Alfred Russel Wallace were the first to propose the theory of natural selection, it's based on observations of natural variation within populations, heritability of traits and the fact that more individuals are born than can survive to reproduce.
