The phospholipids molecules are made up of two fatty acid chain and one glycerol compound which is attached to a phosphate group. Phospholipids are divided into two distinct regions, the head and the tail regions. The head region is polar while the tail region is non-polar.
The phosphate group which is located at the head region of the phospholipid molecules causes the glycero head to become hydrophillic [water loving]. Thus, the phosphate group impact polarity property on the head region of the phospholipid molecules.
Answer:
a. The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs. Hairs and mucus lining the nasal cavity help to trap dust, before it reached the inner portions of the body.
b. It filtered the air to protect you from illness irritation of the respiratory tract
c. It traps smaller particles like pollen or smoke.
d. It regulate the passage of air to the lungs and food to the esophagus. The throat, is the passageway leading from the mouth and nose to the esophagus and larynx.
e. It seal off the windpipe during eating, so that food is not accidentally inhaled.
f. Glottis opens into the windpipe and is responsible for the production of sound
g. It serves as passage for air and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles.
h. It helps support the trachea while still allowing it to move and flex during breathing.
i. It produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts.
j. It takes up the oxygen you breathe in and keep your body going.
Explanation:
<span>The scientific community ensure that all work done and shared is purely objective and based on solid facts and complete experimental procedure. Therefore, the scientific method is adopted to avoid bias in experiments. A bias would cause results to be skewed to fit the researchers' personal views, making the finding unreliable.</span>
Amino acids that must be obtained from foods in order for the body to function properly are called <u>essential amino acids.</u>
<u></u>
- The body is unable to produce essential amino acids. They must therefore originate from food.
- Organic substances known as amino acids are primarily made up of nitrogen, carbon, hydrogen, and oxygen.
- Twenty distinct amino acids are required by your body for growth and optimal operation. Despite the fact that all 20 of these are crucial for your health, just nine are considered essential.
- These include <u>valine, tryptophan, isoleucine, leucine, lysine, methionine, phenylalanine, and threonine.</u>
- While your body may produce non-essential amino acids, it is unable to produce essential amino acids; therefore, you must obtain them through diet.
- Animal proteins including meat, eggs, and poultry are the richest providers of necessary amino acids.
- But some plant meals, such edamame and tofu made from soy, do contain all nine essential amino acids. They are "complete" sources of protein.

Cell division in Prokaryotes is more simple because prokaryotes only have one circular chromosome, no nucleus, and few other organelles. However, eukaryotes have multiple chromosomes contained within a nucleus and many other organelles.
