Our entire body is covered with a protective layer of epithelial cells. The layer of epithelial cells acts as the first line of defense against invaders from the exterior. Skin cells are constantly dying. Additionally, they are frequently damaged, and this could lead to gaps in the epithelial barrier. This protective layer of cells is critical to homeostasis. How does our body counter epithelial cell death and damage to maintain homeostasis? A. Through the process of meiosis
B. Through cell replication or meiosis
C. By producing more than 2 daughter cells per meiotic division
D. By showing down the processes of the cell cycle

Lactic acid and energy are produced in muscle cells during choose 1 aerobic respiration cellular respiration anaerobic respiration cellular division

Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. which is most likely to result in the greatest amount of error in their scientific experiment? a.one student measures the plant stem widths by using calipers. the other student measures the widths of the same plant stems again by using a different pair of calipers. b.one student measures the plant stem widths by using calipers. the other student types the measurements as they are taken into a computer spreadsheet. c.one student weighs liquids for the experiment by using a calibrated scale. the other student weighs liquids for the experiment by using a different calibrated scale.
