A student examined two slides in the laboratory, one slide with normally dividing cells and another slide with cancerous cells.
Which statement best predicts what the student will observe on the slide with cancer cells compared to the slide with normally dividing cells? Answer A: The slide with cancer cells will show more cells in interphase because they are growing in preparation for cell division.
Answer B: The slide with cancer cells will show more cells in interphase because the stages of mitosis take longer to complete.
Answer C: The slide with cancer cells will show fewer cells in interphase because the cells are dividing rapidly.
Answer D: The slide with cancer cells will show fewer cells in interphase because the cells are not dividing.
Mutation usually occurs when there is an error in the pairing of gametes during the crossing over stage of meiosis. There are many types of chromosomal mutation and these are: translocation, duplication, deletion, and inversion. Changes in the number of chromosomes may lead to unique changes in physical and behavioral traits of organisms.
Proteins store energy long term, provide lubrication, and insulate the body
Proteins in the form of enzymes catalyze chemical reactions
Proteins provide structures in the body, such as hair and muscles
Proteins in the cell membrane help transport substances into and out of cells
Answer:
Proteins store energy long term, provide lubrication, and insulate the body
Explanation:
Proteins store energy long term, provide lubrication, and insulate the body - this is false, this describes the role of fats.
Proteins in the form of enzymes catalyze chemical reactions - this is true, enzymes are an important class of proteins in the body
Proteins provide structures in the body, such as hair and muscles - this is true, for example our hair is made of a protein called keratin
Proteins in the cell membrane help transport substances into and out of cells - this is true, proteins form important pumps and channels in the cell membrane
