The muscular system contributes to maintaining homeostasis by working with other body systems to regulate body temperature and dilate or constrict blood vessels close to the skin's surface, according to OpenCurriculum. The muscular, nervous, cardiovascular, endocrine and integumentary systems work together to cause sweating and shivering in the body, which contribute to homeostasis.
DNA is made up of deoxyribose sugar while mRNa is made up of ribose sugar. DNA has thymine as one of the two pyrimidines while mRNA has uracil as its pyrimidines base. DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis. DNA is double stranded while mRNA is single stranded.
Hope this is helped ;)
After the digestion of carbohydrates, fats, and proteins in duodenum, the digested nutrients are absorbed in the ileum.
Ileum is a section of the small intestine, after duodenum.
Food is absorbed by diffusion and active transport. Villi on the walls of the ileum helps this process, since it can increase its surface area and provide a good blood supply, thus increase the rate of absorption.
Note that water can also be absorbed in the large intestine, those water absorbed there are the ones that cannot be absorbed in the ileum.
However, not all water is absorbed as we can notice that faeces are wet.
Answer:
Biodiversity will increase which will make the ecosystem more immune towards diseases and changes in weather.
Explanation:
Example: If u have 1 type of fish in a lake and suddenly the water became salty for some reason, that kind of fish may not survive and if it doesn't there will be no life left in the lake, but if there were multiple types of fish and other animals then some of them would be able to survive and adapt on the change in environment. Hope I helped!
Answer;
B) Neurons, epithelial cells
Explanation;
-Primary lateral sclerosis (PLS) is a rare neuromuscular disease with slowly progressive weakness in voluntary muscle movement. PLS belongs to a group of disorders known as motor neuron diseases. PLS affects the upper motor neurons (also called corticospinal neurons) in the arms, legs, and face.
-It occurs when nerve cells in the motor regions of the cerebral cortex (the thin layer of cells covering the brain which is responsible for most higher level mental functions) gradually degenerate, causing movements to be slow and effortful. The disorder often affects the legs first, followed by the body, trunk, arms and hands, and, finally the bulbar muscles (muscles that control speech, swallowing, and chewing).
