In humans, a pair of chromosomes (one from each parent) determines the sex of the baby. Females have
two X chromosomes, while males have an X and a Y chromosome. The baby always gets an X
chromosome from the mother, so in humans, the father determines the sex of the baby by supplying it with
either an X chromosome to make it female, or a Y chromosome to make it male. In birds, like in humans, a
pair of chromosomes determines the sex. Birds with two W chromosomes are male. Birds with a W
chromosome and a Z chromosome are female. Which statement is true about birds?

A species may live in association with another species. Such an arrangement is called symbiosis.
Symbiosis in which both species benefit is called mutualism. If the symbiosis is beneficial to one species
and neither beneficial nor harmful to the other, it is called commensalism. If one species benefits at the
expense of the other, the relationship is called parasitism. A tick that attaches to the skin of a human or
animal and feeds on its blood is an example of

An island in the Adriatic Sea was overpopulated with snakes. Sailors who came to the island brought and
let loose mongooses, animals that feed on snakes. The population of snakes started decreasing, since the
mongooses were eating them. The mongoose population started increasing since there was ample food
around. The mongooses were not native to the island and there was no predator on the island to keep the
mongoose population in check. At some point, there were hardly any snakes left on the island, and people
started populating it. The mongoose, facing a shortage of snakes, started eating chickens that people kept
for their eggs and meat. However, people caught on and protected the chickens from getting eaten. The
mongoose population decreased. Some remain on the island, but their number is now at equilibrium, kept
in check by the availability of food.
The passage illustrates

There are four blood types in humans: A, B, AB, and O. An individual with blood type A has antibodies for B,
so he or she can't receive type B blood. Similarly, a person with blood type B has antibodies for type A and
can't receive type A blood. A person with AB blood type has no antibodies and can receive blood from
anyone. A person with type O blood has both A and B antibodies and can receive blood only from someone
else with type O blood. Based on this information, someone with type B blood can donate to
