If there is a newly discovered lineage that is a sister lineage to the lineage containing lizards and salamanders, it is most likely that this newly discovered lineage shares a common ancestor with the lineage containing lizards and salamanders.

The term "lineage" refers to a series of organisms, populations, cells, or genes that are derived from a single ancestor. The term "sister lineage" refers to two or more lineages that share a common ancestor but diverged from each other. Thus, if there is a newly discovered lineage that is a sister lineage to the lineage containing lizards and salamanders, it means that this newly discovered lineage is closely related to the lineage containing lizards and salamanders and shares a common ancestor with it. The statement "shares a common ancestor" means that this newly discovered lineage diverged from the lineage containing lizards and salamanders at some point in the past but they share a common ancestor from which they both descended. Therefore, it is most likely that this newly discovered lineage also has some traits or characteristics in common with the lineage containing lizards and salamanders due to their shared ancestry.

The effect of different cereal flours, e.g. wheat, barley, corn and rice flours on the lesser mealworm, Alphitobius diaperinus (Panzer) has been worked out. Cereal flours reduced the growth of all the developmental stages of the beetle. The pupal and adult recoveries (%) were also lowered, and the larval and pupal durations were lengthened in the tenebrionid when grown on cereal flours. The fecundity and egg viability (%) of A. diaperinus were also significantly reduced when reared on these flours.

Studies show that the average global temperature of oceans is rising at both the surface and in the deep ocean. Given how the temperature affects water's ability to absorb gases, the most likely happening to the ocean's ability to absorb carbon dioxide, nitrogen, and oxygen is decreasing. Thus, the correct option is A.

Climate change are the long-term shifts in the temperatures and weather patterns of the planet. These shifts in climate may be natural, but since the period of 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels such as coal, oil, and gas, which produces heat-trapping gases.

Oceans are the largest heat sink on the planet. They absorb about 90% of the excess heat which is caused by climate change. Oceans are also a very efficient carbon sink, which absorbs about 23% of the human-caused carbon dioxide emissions. If they fail to absorb the gases from ecosystem, this may result into increase in temperature of the ecosystem.

Therefore, the correct option is A.

The long term results of planting more genetically modified crops with an increased tolerance to insects are complex and multifaceted, and there are both potential benefits and potential risks that need to be considered.

One of the potential long term results of planting more genetically modified crops with an increased tolerance to insects is a decrease in the use of pesticides. This can have a positive effect on the environment, as there will be less chemical runoff into waterways and less potential for harm to non-target species.

However, there is also the potential for insects to develop resistance to the genetically modified crops, leading to a need for new methods of pest control.
Another potential long term result is an increase in crop yield, as the crops will be less likely to be damaged by insects. This can lead to a more stable food supply and potentially lower food prices.
However, there are also concerns about the potential impact of genetically modified crops on biodiversity and the potential for unintended consequences.

For example, there could be unintended effects on other species in the ecosystem or potential health risks for humans consuming the crops.

Explanation:

The initial outcome of decreasing the number of photosynthetic organisms on earth with no change in the number of organisms using cellular respiration would be a. carbon dioxide levels would increase

Photosynthetic organisms, such as green plants and algae, are those that transform light energy into organic molecules using photosynthesis. They are the primary producers in almost all terrestrial and aquatic ecosystems, generating the basic food source for nearly all animals, including humans. The organisms that undergo cellular respiration, on the other hand, are animals, fungi, and other bacteria that respire organic substances, such as sugars, to acquire energy for their metabolic processes. They are consumers that depend on producers to survive.

Carbon dioxide \((CO_{2} )\) is produced during the respiration process. The more the number of organisms using cellular respiration, the greater the amount of \((CO_{2} )\) they will release into the environment. Because there is no change in the number of organisms using cellular respiration, a decrease in photosynthetic organisms would result in an increase in \((CO_{2} )\). This is because there would be fewer producers using \((CO_{2} )\) and more consumers respiring \((CO_{2} )\), resulting in an overall increase in the atmospheric \((CO_{2} )\) concentration.

As a result, decreasing the number of photosynthetic organisms on earth with no change in the number of organisms using cellular respiration would cause carbon dioxide levels to rise. Therefore, option A is the correct answer.

The statement about when constructing a standard curve, you always include the unknown as one of the data points on the line is false the standard curve is created using known concentrations.

A standard curve is a graph with a series of known concentrations of a particular analyte along the horizontal (x) axis, and the response produced by the same analyte under identical conditions along the vertical (y) axis. The analyte is the chemical or compound you're measuring (for example, glucose or cholesterol), and the response is the measurement signal that corresponds to that analyte's concentration (for example, absorbance, fluorescence, or luminescence).

Thus, when creating a standard curve, you do not include the unknown in the data points on the line. The standard curve is created using known concentrations, and then the unknown is determined by comparing its value to the established curve.
