Across
3. A sugar normally present in milk.
4. What the air temperature actually
feels like to people. This varies
with the relative humidity of the
air.
8. An enzyme produced by mammals to
break down milk sugar that they
consume. This enzyme is needed
for the digestion of uncooked
dairy products. A deficiency of
it results in diarrhea and other
symptoms of physical intolerance
of most dairy products.
9. The medical condition of babies
and very young children resulting
from a severe protein deficiency
in their diet. Symptoms include
edema (or swelling) due to water
retention (especially in the
abdomen), stick-like legs and arms
with little fat or muscle mass,
apathy, and loss of hair and skin
pigmentation in patches. As in
the case of marasmus, children
with this disease are likely to
have their growth retarded.
11. What happens to the body when it
is deprived of sufficient oxygen.
12. The process by which populations
of organisms respond to long term
environmental stresses by
permanent genetic change—i.e.,
evolution.
13. The people who are native to the
harsh arctic and subarctic regions
of North America and Greenland.
17. A change in the normal growth
patterns and development of an
individual that occurs in
childhood as a result of specific
cultural practices or other
environmental processes. The
anatomical and physiological
changes that result are mostly
irreversible by adulthood.
Example: stunted growth and mild
mental retardation due to severe,
prolonged undernourishment.
18. The measure of the total energy
utilized by the body to maintain
necessary body processes. It is
also the minimum level of heat
produced by the body at rest.
19. He said that within the same
species of warm-blooded animals,
there is a tendency for more
heavily pigmented skin to occur in
animals near the equator and
lighter pigmented skin farther
from it.
20. The freezing or partial freezing
of part of the body, especially soft tissue. This condition may
result in gangrene and the loss of
appendages, such as fingers and
toes.
22. The medical condition resulting
from prolonged undernourishment.
Symptoms include extreme
emaciation, diarrhea, anemia, and
apathy. Children who survive this
condition usually develop short
adult stature and some degree of
permanent brain damage.
23. The medical condition resulting
from an unusually high core body
temperature.
24. Cells that produce melanin in the
skin of humans.
25. The process of losing heat by
giving off infrared rays from the
surface of our bodies. Other
processes responsible for human
heat loss are convection,
conduction, and evaporative
cooling.
26. He said that within the same
species of warm-blooded animals,
individuals from populations
living in colder environments
usually have shorter appendages than do those from populations in
warmer areas. |
Down
1. A term for the temperature of an
individual’s internal organs in
the chest cavity, abdominal
region, and head.
2. An inadequacy or an excess of some
key element(s) in the diet, such
as proteins or specific minerals
and vitamins.
5. Abnormal accumulation of fluid in
the lungs resulting from severe
oxygen deprivation at high
altitudes. This can cause
pneumonia-like symptoms and death.
6. Temporary changes in the body in
response to environmental stresses
such as high or low temperatures,
intense ultraviolet radiation from
sun light, or high altitude.
These anatomical and physiological
changes are usually reversible.
Example: developing a suntan in
the summer and losing it in the
winter.
7. An organic pigment produced in the
skin. High concentrations of this
pigment near the surface of the
skin result in a darker
complexion. Suntanned skin also
has higher concentrations of it.
10. The medical condition resulting
from an unusually low core body
temperature.
14. The process by which individual
organisms respond to environmental
stresses during their lifetime
without changing genetically.
These changes are generally not
inheritable.
15. A severe deficiency of calories in
the diet.
16. A constriction or narrowing of
blood vessels resulting in a
decrease in the flow. This is the
opposite of vasodilation.
21. He said that within the same
species of warm-blooded animals,
individuals from populations
living in colder environments
usually have greater body mass
than do those from populations in
warmer areas. |
