During colonoscopy, a flexible Fiberoptic or video colonoscope is used to visualize, examine and photograph the large intestine including the anus, the rectum and the sigmoid, transverse and ascending colon. This procedure is most frequently used for cancer screening and for surveillance in patients with previous colon cancer or polyps. In addition, tissue biopsies can be obtained as needed and polyps can be removed and evaluated. Other uses of colonoscopy include the evaluation of patients with diarrhea of unknown cause, occult bleeding, or anemia; further study of abnormalities detected after a barium enema and diagnosis clarification and determination of the extent of inflammatory or other bowel disease. Colonoscopy is contraindicated if the patient has a suspected or documented colon perforation, acute severe diverticulitis or fulminant colitis.

Answer no 1:

The part labelled A is the upper epidermis . The main function of the epidermis is to protect the structure of the leaf.

The part labelled B is palisade tissues. These are the sites where the chlorophyll are present.

The part labelled C are the air spaces in the spongy mesophyll tissue. They allow carbon dioxide to move freely.

The part labelled D are the vascular tissues which transport water and food.

Answer No 20:

The correct option is B) Most of the carbohydrates are made in the palisade mesophyll.

The palisade mesophyll comprises of chloroplast which are the sites where photosynthesis takes place. Hence, these will be the sites where carbohydrates will be manufactured.

Answer No 21)

Cell Division Homework #1 Introduction to Cell Division Directions: Compare and contrast the following pairs of terms:
wel

Answer:

Sister chromatids / centromeres: When a single chromosome has been replicated in copies, each copy is called a sister chromatids.

A special part of the chromosome called the centromere holds the two sister chromatids together. A centromere is like a built-in rubber band for two sister chromosomes.

Mother cell / daughter cell: identical.

Daughter cells are genetically identical to the mother cell at the stage of production through mitosis.

On the other hand, at the stage of production through meiosis, the daughter cells are genetically different and contain only half of the genetic material of the mother cell.

Interphase / cell division: A cell spends most of its time in what is called interphase, and during this time it grows,

replicates its chromosomes, and prepare for cell division.

The cell then leaves Interphase, undergoes mitosis, and completes its division.

DNA / chromosome: Genes are segments of deoxyirbonucleic acid (DNA) that contain the code for specific protein that functions in one or more types of cell in the body

Chromosomes are structures within cells that contains a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Mitosis / cytokinesis: Basically, mitosis is a process by which the duplicated genome in a cell is separated into halves that are identical in nature.

Cytokinesis is the process where the cytoplasm of the cell divides to form two 'daughter' cells. The result is the formation of two 'daughter cells', each having a nucleus.
