Answer:
Crossing over is a process in which exchange of segments occur between two non sister chromatids.
Explanation:
Crossing over is a process in which two non-sister chromatids of homologous chromosomes exchange the segments of genetic material with each other during meiosis. Due to this process, variation occurs in an organism.
Independent assortment is a process in which different alleles are sorted to different gametes which occurs independently and does not effect one another. This process occurs in metaphase of meiosis l.
Joining of sex cells is a process in which sex cells of male and female join together formed a zygote which turn into a new organism. These sex cells are formed during meiosis which are haploid in nature.
Mutation and crossing over are the factors that cause inherited genetic variations within populations.
Sudden change occurs in the genes of an organism due to the exposure of the cell to radiation or chemicals.
Lysosomes use or make use of hydrolyzing and other digestive enzymes to break down foreign matter and dead cells. Upon releasing such substances, these substances are broken down and are released from the cell.
The second answer. The atmosphere blocks of absorbs them.
Answer:
Serum or urine components
Explanation:
Multiple myeloma is the cancer developed in the plasma cell that is a kind of white blood cell. The plasma cell helps in production of antibodies that protects the body from infection. Multiple myeloma causes the cancerous cells to aggregate in the bone marrow and covers the healthy cells.
The diagnosis of this type of cancer includes bone marrow biopsy, urine and blood tests. The bone marrow plasmocytosis includes the increase in plasma cells number in the bone marrow. The areas of bone damage that are due to cancerous plasma cell are the lytic bone lesions.
The proteins produced by the cancerous cells are detected in serum and urine samples. Thus, definitive diagnosis of multiple myeloma includes the triad of bone marrow plasmacytosis, lytic bone lesions, and <u>Serum</u>.
