Answer:
Moves down the concentration gradient
Explanation:
Since diffusion moves materials from an area of higher concentration to an area of lower concentration, it is described as moving solutes "down the concentration gradient" (compared with active transport, which often moves material from area of low concentration to area of higher concentration...
The correct option is IPSILATERAL. The anatomical path of a reflex is called reflex arc. An ipsilateral reflex arc is one in which the motor output occur on the same side of the body where the stimulus is detected. Apart from ipsilateral reflex arc, there are other two types, which are conlateral and intersegmental reflex arc.
Polygenic traits are those traits that are controlled by more than one gene. Such traits may even be controlled by genes located on entirely different chromosomes. Human height, eye and hair color are examples of polygenic traits. Skin color is another polygenic trait for humans and a variety of other animals.
Answer:
Radiation, chemical, and infectious agents are mutagens or environmental factors that can cause a mutation
Explanation:
Mutagens are agents that can interfere with DNA and cause a mutation. They can cause chemical changes, structural changes or breakages that end up altering the sequence of the DNA. This results in mutations which can cause diseases such as cancer.
Contraction of skeletal muscles against the lymph vessel
The lymph usually move in the body in its own vessel and travels from the interstitial spaces to the subclavian veins at the neck area. The lymphatic system does not have a heart to pump and move the fluid. The movement of lymph depends on the movements of the muscles and joints in the body. In this mechanism upward movement is possible. It will move towards the neck where it will be filtered and will go again into the subclavian veins.
