Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time. Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation. Often cells can recognize any potentially mutation-causing damage and repair it before it becomes a fixed mutation.
Mutations contribute to genetic variation within species. Mutations can also be inherited, particularly if they have a positive effect. For example, the disorder sickle cell anaemia is caused by a mutation in the gene that instructs the building of a protein called hemoglobin. This causes the red blood cells to become an abnormal, rigid, sickle shape. However, in African populations, having this mutation also protects against malaria.
However, mutation can also disrupt normal gene activity and cause diseases, like cancer. Cancer is the most common human genetic disease; it is caused by mutations occurring in a number of growth-controlling genes. Sometimes faulty, cancer-causing genes can exist from birth, increasing a person’s chance of getting cancer.
Answer: Other organs and tissues serve a purpose in only one body system. Examples include the respiratory system, nervous system, and digestive system.
Explanation:
Body systems are groups of organs and tissues that work together to perform important jobs for the body.
Glucose Molecule is formed during the light-independent phase of photosynthesis
Explanation:
In plant Carbon dioxide enters through stomata and in stomata it is diffuses over small distances through the inter-cellular process. it reaches the mesophyll cells.
The other name of light independent phase is Calvin cycle whose name is in name of the person who discovered it. The light is not involved in this reaction so it is called light independent or dark cycle.

♡Henlo, here's your answer♡
~They use pseudopods to move away from bright light or to trap food.
Therefore, yes, they do use similar structures to move.
