Answer: pollen
Explanation: The anthers bear the pollen grains which contains the male gamete(sperm).
In this case, it is given that <em>Mycoplasma pneumoniae </em>lacks cell wall. some antibiotics such as penicillin works by interfering the synthesis of the cell walls. As these microbes do not have cell wall, the penicillin like antibiotics would not work.
In this case, the antibiotics, which interferes with the DNA (deoxyribonucleic acid) formation and replication can work. The ciproflaxin is an antibiotic, which work by inactivating the enzyme required for DNA replication in bacteria. Hence, the antibiotic ciproflaxin would be effective for treating the given condition.

The urinary system is the main excretory system of the body after the gastrointestinal tract (large intestine) and lungs, In these questions it is necessary to prioritize the urinary tract.
The right answer is D. Bladder
The bladder belongs to the urinary excretory system.
The bladder receives the urine produced by the kidneys via the ureter and has the function of storing it before its elimination during urination through the urethra. The muscles surrounding the bladder help to prevent urine reflux to the ureter.
The right answer is C. Kidneys
The main purpose of the renal excretory system is to eliminate nitrogenous wastes while maintaining homeostasis, all through the formation of urine.
The kidney has a secretory function (filtration of blood in the glomeruli) and excretory from the pyelon (triangle based on the renal hilum) origin of the ureter. We speak of pyelo-ureteral junction. Each kidney contains about 1 million nephron.
In natural selection, there are three main things you need to know. There must be a variance in the genepool of course, or else to selection or evolution will take place. There also must be a selective force and time. Now, lets say that there is a population of many colored moths. But lets say that the brown colored moth blends in with the environment. This means that predators (selective force in this case) will have a much harder time finding these brown moths instead of easily finding some of the other colored moths (variation). This means that the brown moths will survive at a much higher rate because the are harder to find, and over time, the gene pool will narrow down to just brown moths because the rest of the moths die out due to predators and competition. This also means that this moth species has evolved over time to just become the brown colored moths only. Hope you can understand this but feel free to ask for clarification.
