Answer:
Yes
Explanation:
In the atmospheric pressure present at sea level, water boils at 100 °C (212 °F). At an altitude of 63,000 feet (19,000 m), it boils at only 37 °C (99 °F), the normal body temperature of humans. This altitude is known as Armstrong's Line. In practice bodily fluids do not boil off at this altitude.
Answer:
There are 11 major organ systems in the human body.
Explanation:
The 11 organ systems include the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems.
The nine major organ systems in the human body are the integumentary system, the musculoskeletal system, the respiratory system, the circulatory system, the digestive system, the excretory system, the nervous system, the endocrine system, and the reproductive system.

<u>enzymes</u>
<h2>
Explanation:</h2>
Chemical reactions convert <u>reactants</u> to <u>products</u>. In nonliving systems, the presence of a(n) <u>catalyst </u>allows the reaction to proceed very quickly and have a lower <u>activation energy</u>. In living systems, this function is carried out by proteins called <u>enzymes</u>.
The phylum Echinodermata , which contains about 6000 species, gets its name from the Greek, literally meaning "spiny skin." Many echinoderms actually do have "spiny" skin, but others do not. This phylum exists exclusively in the sea, and cannot be found on land or in fresh water. All echinoderms have one thing in common: radial symmetry. This means that the creatures have appendages (or body construction) which point outward from the center of the body like the spokes on a bicycle wheel. Furthermore, these appendages usually occur in multiples of five, although there are a few exceptions. There are several well known members of this group, like sea stars and sea urchins. The radial symmetry is obvious in these creatures.
