In human body, three types of blood cells are present, which include red blood cells, platelets, and white blood cells. Although these cells are started out alike, they show different shapes, sizes, and functions due to instructions that differentiate them into different types. These instructions are given by particular chromosomes present in the cells as the chromosomes consist of DNA that provides information to the cells, which is responsible for characteristic behavior of that cell.
Hence, the correct answer for the blank is 'B) chromosomes.'
In biological systems, the chemical reactions concerning glucose and ATP as a product are vital for cellular respiration and photosynthesis. Shortcuts reduce the activation energy, which increases the net "gain" of products. I would go with the last one.

According to the model, the "villi" of small intestines is being damaged as an impact of celiac disease. Small intestines are responsible for absorption of nutrients and minerals from food, this occurs through villi, in case of damaged villi absorption is interfered, thus disturbing the digestive system. If the nutrients, minerals or vitamins are not being absorbed well by small intestines then they will be excreted out of the body and will not be transported to the blood and other areas, this would result in deficiency of minerals and vitamins in blood that cause weakness.

Answer: Well for one, Differentiate is when a cell matures and is used in a specific function. Meristem is a cell which never differeates and constantly divides so it is a mitotic cell. Elongation is the plant growing length wise therefore the meristem elongates the plant. Vascular cambium is the cambium which starts out in vascular bundles of the plant and then grows to form a ring inside the stem of plants that live for more than year- it causes and increase in thickness of the stem and branches.
hope this helped luv :)
