Musk oxen are large animals that live in the coldest parts of the
artic and look something like shaggy cows. musk oxen have the
warmest wool of any mammal. How would a biologist explain how musk
oxen evolved this warm wool, assuming that their ancesotrs had wool
that was less warm?
Solutions
Expert Solution
1) Theory of Natural selection;
The Musk oxen have large hais which are not found in their common ancestor. And these hairs are look like shaggy cows. The musk oxen living this condition for many generation. There is found natural selection for the hair trait in the Musk individual. The individual which have Musk hair will survive more because the shaggy hair protect them from cold. Hence they reproduce more. And passes the trait to the offsprings. That's why the Musk oxen develops shaggy hair over generation.
2) convergent evolution:
The Musk oxen and Shaggy cow live in same environmental condition. There is found different ancestory but they merge to a single phenotype for the hair. This is the case of convergent evolution

Animals that live in colonies with alarm calls usually live in
large family groups. Animals that use alarm calls put themselves at
risk but increase the chances of their relatives’ survival. Alarm
calls put the caller at increased risk of predation by drawing
attention to its location. Why might this behavior be favored by
evolution?

Why would it be more challenging for animals to live during a
time when temperatures are fluctuating than in a time when
temperatures are more stable?

Arctic ground squirrels are small (~ 1 kg) animals that live in
a very cold climate. As such, they have evolved to spend a
significant portion of the year in hibernation where their body
temperature can drop as low as -3 C.
(A) If, at the time hibernation starts, the squirrel is 30% fat
(stored as tripalmitoylglycerol; 40 kJ/g) and consumes 15 kcal/day
while hibernating, how long can the squirrel stay in hibernation?
Provide your answer in days.

At a large university it is known that 45% of the students live
on campus. The director of student life is going to take a random
sample of 100 students. What is the probability that more than half
of the sampled students live on campus?

By and large, the features observed in animals, plants, fungi,
and biological organisms, in particular, are representative of
their function and shaped by natural selection in the context of
their environment. When we, as scientists, observe forms in nature,
such as differing limb structures in vertebrates, varying tooth
shapes in mammals, a diversity of leaf shapes in trees, or even the
different shapes and sizes of cell types, we see both the function
of the trait in question as well...

1. Anthrax spores can cause a very bad disease in humans and
animals. The spores look like the inset micrograph. Although not
quite spherical, when they are in the air they act very much like
spheres with a diameter of about 0.9 µm (.9e-6 m) and density (when
they are dried out) of 1.42 g/cubic centimeter (1,420 kg/m3), and a
total mass of about 540 fg (femtograms) which in kilograms is about
5.42 e-16 kg. When the spores are falling...

A sample of 1000 people that live in a large city was asked if
they believed that the city’s sales tax proposal was warranted. If
at least two-thirds of the city’s citizens believe that the sales
tax is warranted, then the mayor will take immediate steps to
formally propose the tax. The survey responses showed that 692 of
the 1000 people surveyed believe that the tax proposal is
warranted.

A large population of fish live in a lake. The color of their
scales is determined by two different alleles of the S
gene, S1 and S2. Homozygous S1 fish have
yellow scales, S2 homozygotes have blue scales, and
heterozygotes are green. Scientists catch 100 fish at random and
record their colors. Among those 100 fish are 30 yellow, 50 blue,
and 20 green ones.
