Answer: to protect the body from invasion in the gut
Explanation: Gut-associated lymphoid tissue (GALT) is a component of the mucosa-associated lymphoid tissue (MALT) which works in the immune system to protect the body from invasion in the gut.
Answer:a) a sturdy-finned, shallow-water lobe-fin whose appendages had skeletal supports similar to those of terrestrial vertebrates.
Explanation:
An ancestor - An earlier type of a species at any distant time — a progenitor.
A tetrapod is any vertebrate with four limbs. It includes any vertebrate (such as birds or snakes) that have evolved from early tetrapods — especially all members of the superclass Tetrapoda.
The presence of bones that support the appendages in Lobe – fin fish were found to be similar to the categorical skeletal supports found in the limbs of sample tetrapods. The sub class crossopterygii includes the Lobe – fin fish, which is seen as one of the recent common ancestor of living tetrapod today.
Answer:
relating to genes or heredity or relating to origin, or arising from a common origin.
Explanation:
Answer:
Most likely diagnosis is Basal Cell Carcinoma (BCC), most likely caused by years of prolonged exposure to sunlight over time.
Explanation:
Basal Cell Carcinoma (BCC) is a common type of skin cancer that develops when the basal cells that is responsible for producing new skin cells when they die, become mutated and causes the basal cell to abnormally multiply rapidly and continues to grow. The accumulation of these abnormal cells is what results in cancerous tumors that appears like ulcers on the skin. Prolong and intense exposure to the ultraviolet (UV) radiation from sunlight has been linked to the most likely cause for the mutation of the DNA in the basal cells which leads the abnormal cell growth and multiplication. People who expose themselves to the radiation of the sun for longer periods, over time, are at high risk of developing this cancer.
