The defecation reflex involves two postive feedback loops. these loops are the stretch receptors in the rectal walls and the sacral parasympathetic system. Defecation reflex empties the rectum by peristaltic movements push fecal matter from the sigmoid colon into the rectum. Then this distension of the rectal walls stimulates stretch receptors which results in defecation.

Answer: DNA
Explanation:
DNA also referred to as deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Almost every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus.
Answer:
Green peas if it does not have a dominant allele for yellow peas.
Explanation:
In pea plants, yellow is the dominant allele color of peas and green is the recessive allele color of the pea. So the genotype that makes yellow color pea is YY or Yy and the genotype that is responsible for producing green color pea is only YY.
This shows that homozygous dominant or heterozygous dominant condition gives rise to yellow color pea and only homozygous recessive condition would give rise to green color pea plants.
Therefore if a pea plant has the recessive allele for green peas it will produce green peas if it does not have a dominant allele for yellow peas.
Yes, the all living tissues contains the catalase, Catalase protects cellular organelles and tissues from damage by peroxide.
<h3>
Do all living tissues contain catalase?</h3>
Catalase is a common antioxidant enzyme which is present in all living tissues of an organism and it is responsible for the degradation or reduction of hydrogen peroxide to water and molecular oxygen using either iron or manganese as a cofactor.
Liver, potatoes and other living tissues contain the enzyme catalase. This enzyme breaks down hydrogen peroxide which is a harmful by-product of the process of cellular respiration. If it builds up in concentration in the cells, the cells are adversely affected which leads to serious complications in the organisms.
So we can conclude that all living tissues contains the catalase, Catalase protects cellular organelles and tissues from damage by peroxide.
