Wind is the natural resource which is renewable. Therefore, option (B) is correct.
Wind energy is considered a renewable resource because it comes from the natural flow of air masses caused by the sun and the Earth's rotation. Wind turbines turn the kinetic energy of the wind into power, and as long as there is wind, this process can keep going forever.
Wind doesn't run out like coal and oil (options A and D), which are both solid fuels. Topsoil (choice C) is an important resource for agriculture, but it can be worn down or eroded over time, making it non-renewable in the short run if it is not managed well.

Use the data you calculated in parts A and B to explain why gypsy moths could threaten biodiversity in the ecosystem.
Answer: edmentum
The number of gypsy moths is growing exponentially in a short period of time, which suggests that there are few predators controlling their population. This growth also aids the exponential destruction of shrubs and trees, which native species rely on for food and shelter. Increased competition for these resources will likely cause the population of many native species to decline. Over time, some of the native species may die out or leave the area, leading to a decline in biodiversity.
Answer:
The number of moths are growing fast in just a short period of time, this means that their poulation is being controlled by their predators. As the population of the moths continue to grow, there will be an increase in the destruction of crops and trees within the moth's environment. Over time some of the species may die out and cause them to relocate and cause a decrease in biodiversity.
Explanation:
I put this answer in my own words, so you may copy and paste it.
The caterpillar of the Gypsy Moth provokes tree damage but since it is the only stage of the life cycle that utilizes food. When the population of feeding caterpillars reaches pandemic proportions, they can completely defoliate trees.
What is a biodiversity?The term biodiversity pertains to the diversity of life on Earth at all levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that enable life to exist.

How does the shape of organ relate to gene expression?
Answer:
The alleles for MADS-box genes get expressed at different levels. They form the “L” complex and the “SP” complex. These are a group of proteins that determine the shape of the petals. The more they L complex is expressed, the high the probability that the petals of the flower will form the ‘lip’ and the high the SP complex is expressed then the high the likelihood of dominant petals.

2. 2,3-bisphosphoglycerate is an allosteric inhibitor of oxygen binding to hemoglobin. a. Acclimatization to high altitude involves numerous physiological and biochemical changes, including an increase in the concentration of 2,3-bisphosphoglycerate in red blood cells. Explain why the 2,3 bisphosphoglycerate concentration increases at high altitude. b. The 2,3-bisphosphoglycerate concentration in maternal red blood cells also increases during pregnancy. Why
Answer:
A. At high altitude, increase in 2,3-bisphosphoglycerate (BPG) ensures that enough oxygen is delivered to the tissues despite the low oxygen saturation levels there.
B. An increase in 2,3-bisphosphoglycerate (BPG) is necessary during pregnancy as it ensures that both the pregnant woman and developing fetus have enough oxygen for their metabolic needs.
Explanation:
Atmospheric pressure is low at high altitudes with the result that oxygen molecules in the air are further apart. The reduction of oxygen availability in the air thus reduces the oxygen saturation in the blood and brain. Oxygen saturation levels refer to the extent hemoglobin is bound or saturated to oxygen.
2,3-bisphosphoglycerate (BPG) is an allosteric inhibitor of oxygen binding to hemoglobin. At low concentration, oxygen delivery to tissues is low while at hgh concentrations, oxygen delivery to tissues increases. It ensures that oxygen bound to hemoglobin in blood from the lungs is delivered to the tissues. Thus, at high altitude, increase in BPG ensures that enough oxygen is delivered to the tissues despite the low oxygen saturation levels there.
B. During pregnancy, there is a significant increase in oxygen demand. This is due to a 15% increase in the metabolic rate and a 20% increased consumption of oxygen as the developing fetus obtains nutrients and oxygen from the mother's blood.
An increase in 2,3-bisphosphoglycerate (BPG) is necessary during pregnancy as it ensures that both the pregnant woman and developing fetus have enough oxygen for their metabolic needs.

Many of the hardest rocks are metamorphic rocks. Why do you think metamorphic rocks are harder than sedimentary rocks?
Answer:
Metamorphic rocks are almost always harder than sedimentary rocks. They are generally as hard and sometimes harder than igneous rocks. They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are eroded away.
Because their mineral grains grew together tightly during metamorphism, they're generally strong rocks.

Fibroblasts can be placed on thin sheets of silicone rubber. Under normal circumstances, fibroblasts exert sufficient tension on the rubber so that it visibly wrinkles. Explain how the ability of fibroblasts to wrinkle rubber would change if the cells were treated with a permeable form of C3 transferase, a toxin (from the bacterium Clostridium botulinum) that covalently modifies an amino acid in Rho. The modification renders Rho unable to bind to proteins that it would normally bind to when active.
Answer:
C3 transferase decreases Rho activity and contractility by decreasing the number of stress fibers and thus also reducing wrinkles
Explanation:
Rho protein is a small GTPase, i.e., an enzyme that binds GTP to hydrolyze it to GDP, which is known to mediate the formation of stress fibers and focal adhesion. Rho protein is involved in diverse cellular functions including, among others, adhesion, motility, and division by reorganization of the actin cytoskeleton. The bacterial toxin C3 transferase derived from Clostridium botulinum is able to lock Rho in an inactive state. C3 transferase adds an ADP-ribose to Rho, thereby leading to the accumulation of a Rho-guanine nucleotide dissociation inhibitor (GDI) complex in the cytoplasm. In consequence, C3 transferase functions to decrease contractility by blocking Rho activity, decreasing the number of stress fibers and leading to a reduction in wrinkles.
