Answer:
Whiplash occurs when the muscles in your neck suffer a severe strain sue to the abrupt and extreme movement of your head moving backward and then forward. This motion can cause your neck's muscles and tendons to stretch unnaturally, and even tear. Symptoms would include neck swelling, and spasms in the trapezius muscles, cervical spine, and anterior cervical spine.
Explanation:
Answer: b. DNA
Explanation:
DNA is a genetic material commonly found in all living beings. It is present in a thread like structure that is called as the chromosome. The DNA is double helical structure which exhibits the segments of small units called as the genes. The gene is a hereditary material which encodes for a particular protein. Each gene is responsible for determining a particular trait in living beings.
Answer:
Anabolic-builds large molecules from smaller ones/requires Atp
Catabolic- breaks down large molecules into smaller ones/ Produces ATP
Explanation:
Anabolic pathways are those that require energy to synthesize large molecules. Catabolic pathways are those that generate energy by breaking down larger molecules.
Explanation:
a. Nasal cavity: the epithelium in this zone is meant to provide a physical barrier to the invasion of microorganism or particles, it also secretes and remove mucus and foreign particles, these epithelial cells are also involved in the igE producing process (perpetuating allergic responses. <em>The nose is the first barrier to the air that enters our body, that's why the epithelial cells in this zone focus in filtering foreign particles. </em>
b. Bronchiole: epithelium is ciliated and no ciliated, it becomes cuboidal in smaller passages as it continues to branch. The no ciliated cells, also known as club cells are the ones that produce surfactant. <em>Since bronchioles are passages to direct the air to the alveoles epithelial cells in this zone have adapted to go from larger branches to smaller ones to reach the alveoli. </em>
c. Alveolus: it's composed of two types of cells, type one, that constitute the air-blood barrier and type two, cells that produce surfactant to reduce surface tension to keep the alveolus shape when breathing.<em> Since alveoli's function is to allows oxygen/carbon dioxide to move between bloodstream the epithelial cells in this organ evolved to cover this job.</em>
