The equation indicates that in the presence of light, precisely 6 molecules of carbon dioxide will combine with exactly 6 molecules of water to form exactly 1 molecule of sugar and 6 molecules of diatomic oxygen. Because of the law of conservation of matter, the right answer will maintain the original equation's ratio of reactants to products. Only the second answer choice yields a proportionate equation to the original equation: because the coefficient of each reactant is doubled, the coefficient of each product is similarly doubled. The other response options all improperly change the product-to-reactant ratios and violate the rule of conservation of matter.
Salty foods are less prone to bacterial attack because most bacteria can’t grow in environments that are too salty.
Following the emergence of little seeds, the evolutionary branch split several more times, resulting in the development of tomatoes, watermelons, oranges, and lemons.
The number of sulfur and fluorine molecules on either side of the reaction must be equal due to the rule of conservation of matter. As a result, the S8 on the reactant side requires 8 SF6 molecules on the product side. This results in a total of 6 8 = 48 fluorine molecules being produced on the product side, which must be balanced on the reactant side. Fluorine is known to react as F2, and we know that 48 total fluorine atoms are required; dividing 48 by 2 yields the right coefficient for the reacting F2.
It is important to note that environmental impact, E, is positively associated to both population, P, and energy consumption, N, while it is negatively related to new technology development, T. This means that if population or energy demand doubles, so would the environmental impact. It also suggests that doubling the development of new technology reduces the environmental impact by half. If population grows, two scenarios will sustain environmental impact: a corresponding decrease in energy use or a proportional increase in new technology development. Only the second possibility, a rise in technology, is an available answer choice.
The moon's gravitational influence on Earth causes periodic fluctuations in sea levels, often known as tides. Wind intensity can generate waves in ocean waters, but it is insufficient to influence tides. Ocean currents can be caused by density changes in saltwater. The movement of tectonic plates in the water can result in large-scale ocean disasters like tsunamis. Tides are not influenced by density variations or tectonic plate movement since they are not powerful or constant enough.
The offspring of a white (gg) mouse and a grey (Gg) mouse have a 50% chance of having white fur (gg). The complete Punnett square demonstrates that the offspring have a 2/4 chance of possessing the genotype that creates the phenotype for white fur. The other half of the period, the genotype (Gg), which is the phenotypic for grey fur, is obtained.
Someone who has blood type A can donate blood to those who don’t have antibodies for A. These include other people with type A blood (they have antibodies for B only) and those with type AB blood (they don’t have any antibodies).
Natural Selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution. In this case, polar bears with thicker fur were able to better survive in their environment while thinner furred polar bears died off over time.
A wetland is a land area that is saturated with water, either permanently or seasonally. A wetland ecosystem supports many species including, amphibians and reptiles.
Natural Selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring.
Because it is made up of a bar and a fulcrum, a seesaw is an example of a lever. A wedge, also known as an incline plane, is a triangular machine that allows for less effort to be delivered over a longer distance to do the same amount of work. A pulley is a two or more wheeled equipment that provides mechanical advantage while lifting goods using a rope. To increase mechanical advantage, pulleys and levers can be coupled. A seesaw is a lever that does not have a pulley attached to it.
The body must first process the requirement for change and then properly signal the appropriate change given the scenario. Sweating acts as a cooling process by removing heat via evaporation. Shivering generates heat energy through small, fast mechanical muscle movements.
Mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations.
With the introduction and increasing population size of the Grey wolf, the population sizes of the Rocky Mountain wolf and their deer prey decreased, implying that the Rocky Mountain and Grey wolves compete for their deer prey. Mutualism is a relationship in which both members of the interacting populations benefit. It would be surprising to see a decline in the size of the Rocky Mountain wolf population if the wolf species had a mutualistic relationship because neither wolf species is expected to prey on the other. One member of the interacting population benefits and the other is unaffected.
Scientists utilize both independent and dependent variables in experiments. An independent variable is one that scientists adjust in an experiment to see how it affects the dependent variable. The variable being measured is known as the dependent variable. The scientist controls two variables in this study: skin type and UV light. The level of redness on the skin is the dependent variable.
Brewers will be unable to distinguish which variable contributes to a sweeter coffee by modifying two of the variables, brew time and nitrous gas pressure. If they want to experiment with alternative brew times, they should do it in a separate experiment that employs nitrous gas at a consistent pressure.
Animal cells usually don’t have a cell wall. Other statements are true.
Coats provide insulation by reducing the amount of heat lost from the body.
Correct answer is cell, tissue, organ, organ system.
