XX and XY chromosomes are only found in humans.
The XX set of chromosome set is found in females only.
The XY set of chromosome set is found in males only.
Hope this helps!
The biome that covers most of the central United States, from North
Dakota to Texas, is temperate grasslands. Temperate grassland is the
term used for a larger grouping of biomes that includes within it
tropical savannas. They are defined by a dominance of grasses, and have a
large temperature difference between different parts of the year.
The answer should be NEURONES (nerve cells).
Neurons transmit electrical signals called NERVE IMPULSES from the cell body through the axon to the end plate. The junction between the end plate and the adjacent cell is called SYNAPSE. impulses passes through the synapse by diffusion of chemicals.
Answer: Colon cancer
Explanation:
All cancers, but especially colon and rectal cancers, commonly referred to as colorectal cancer (CRC), have hereditary factors that potentially increase one’s risk.
Genetic testing is determine if there is an increased risk of colon cancer. Apolipoprotein E (apoE) plays a major role in the metabolism of bile acids, cholesterol and triglycerides, and has recently been proposed as being involved in the carcinogenic process. Given the potential role of bile acids in colorectal cancer etiology, it is reasonable that colorectal cancer risk might be modified by apoE genotype. The absence of an e3 apoE allele significantly increased the risk of colon cancer especially for individuals above 50years.
