A patient who has been diagnosed with cancer has been given a blood test in order for their doctors to investigate their genetic code. What information from the test would help confirm the patient's cancer diagnosis? A) Data indicating somatic cell production is being inhibited by the patient's cancer cells.

B) Data indicating there is a genetic mutation in a protein controlling the patient's cell cycle.

C) Data indicating gametes are becoming diploid cells due to the introduction of cancerous cells.

D) Data indicating that cells are increasing their chromosome number due to the occurrence of cancer cells.

Mouse liver cells were homogenized and the homogenate subjected to equilibrium density-gradient centrifugation with sucrose gradients. fractions obtained from these gradients were assayed for marker molecules (i.e., molecules that are limited to specific organelles). the results of these assays are shown in the figure. the marker molecules have the following functions: cytochrome oxidase is an enzyme involved in the process by which atp is formed in the complete aerobic degradation of glucose or fatty acids; ribosomal rna forms part of the protein-synthesizing ribosomes; catalase catalyzes decomposition of hydrogen peroxide; acid phosphatase hydrolysis monophosphoric esters at acid ph; cytidylyltransferase is involved in phospholipid biosynthesis; and amino acid permease aids in transport of amino acids across membranes. a) name the marker molecule and give the number of the fraction that is most enriched for each of the following cell components: lysosomes; peroxisomes; mitochondria; plasma membrane; rough endoplasmic reticulum; smooth endoplasmic reticulum.

The pressurized plants and fungi mentioned in the video have some surprising similarities. what differences would you expect them to have?

Which of these is an example of land degradation? a. containers designed to store pollutants leak. b. fertilizers provide too many nutrients to crops. c. garbage is buried so the land can be reclaimed later. d. a drought kills all the plants in an area, leaving bare land
