It is FALSE that it would be impossible to eliminate measles because the measles vaccine is only partly protective.
The measles vaccine, when administered according to the recommended schedule, is highly effective in providing protection against measles. The measles-mumps-rubella (MMR) vaccine is a two-dose series that has been shown to provide long-lasting immunity in the majority of individuals who receive it. The vaccine is estimated to be about 97% effective after two doses.
Measles elimination is feasible through high vaccination coverage rates. The concept of herd immunity plays a crucial role in controlling and potentially eradicating measles. When a high proportion of the population is immune to the virus, it helps protect vulnerable individuals who cannot be vaccinated, such as infants or individuals with weakened immune systems.
While no vaccine is 100% effective, the high effectiveness of the measles vaccine, coupled with robust vaccination efforts and public health measures, has led to the successful elimination of measles in certain regions. Continued vaccination efforts and maintaining high vaccination coverage rates are essential for preventing measles outbreaks and moving towards global eradication.

if there is only a runner on 2nd base and the batter hits a ball on the ground- the fielder must ____________ to get the runner out.
If there is only a runner on 2nd base and the batter hits a ball on the ground, the fielder must make a play to get the runner out.
The specific action the fielder must take depends on the circumstances and the location of the hit ball.Typically, in this situation, the fielder will attempt to field the ball and make a throw to first base to retire the batter. This play is commonly known as a "force play" because the runner on 2nd base is forced to advance to 3rd base when the batter becomes a runner. The fielder's objective is to make a quick and accurate throw to first base before the batter reaches it, thereby forcing the runner at 2nd base to advance to 3rd base.
However, if the hit ball is slow or the fielder is positioned closer to 2nd base, the fielder may opt to make a play directly on the runner at 2nd base, attempting to tag them out before they reach 3rd base. This would be considered a "fielder's choice" play, where the fielder chooses which base to make the out.
The specific action the fielder takes to get the runner out will depend on the speed of the hit ball, the fielder's position, the game situation, and the overall strategy employed by the fielding team.

Fitness is a term used to describe an individual's ability to survive and reproduce in a given environment. Components of fitness are specific traits or characteristics that contribute to an individual's overall fitness.
These components can include physical traits such as strength and endurance, as well as behavioral traits such as aggression and social skills. Reproductive success refers to an individual's ability to produce offspring that survive to reproductive age. It is a key component of fitness, as an individual's ability to pass on their genes to the next generation is a primary measure of their evolutionary success.
When it comes to estimating reproductive success, some components of fitness may be more important than others. For example, physical fitness may play a larger role in reproductive success in species where physical prowess is important for acquiring mates or defending territory. In these species, traits such as strength and endurance may be more strongly correlated with reproductive success than behavioral traits such as social skills.
On the other hand, in species where social skills are critical for acquiring mates or forming alliances, behavioral traits may be more important for reproductive success. In these species, individuals with strong social skills and the ability to form strong bonds with others may be more successful at reproducing.
Overall, the importance of different components of fitness for reproductive success is likely to vary depending on the species and the specific environmental conditions in which they live. While some traits may be more important than others, all components of fitness are likely to contribute in some way to an individual's overall reproductive success.

if a current of 110 μaμa is passed through the leg of a patient, how many chloride ions pass a cross section of the leg per second?
6.868 x 10¹² chloride ions pass a cross-section of the leg per second when a current of 110 μA is passed through it.
The amount of substance produced at an electrode is directly proportional to the quantity of electricity passed through it, as stated by Faraday's law of electrolysis. Therefore, the number of chloride ions passing a cross-section of the leg per second can be calculated using the formula:
Number of ions = (electric current) ÷ (charge carried by one ion)
The charge carried by one chloride ion can be calculated using the charge of an electron and the valency of chloride ion, which is -1. Therefore, the charge carried by one chloride ion is:
Charge carried by one chloride ion = (charge of an electron) x (valency of chloride ion)
= 1.602 x 10⁻¹⁹ C
Number of chloride ions = (110 x 10⁻⁶ A) ÷ (1.602 x 10⁻¹⁹ C)
