The Bond between oxygen and hydrogen is Covalent bond .. ( within the same water molecule)
The force between two or more watter molecules is hydrogen bond. ツ
Mouth. Food starts to move through your GI tract when you eat. When you swallow, your tongue pushes the food into your throat. A small flap of tissue, called the epiglottis, folds over your windpipe to prevent choking and the food passes into your esophagus.
Esophagus. Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins.
Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach. This sphincter usually stays closed to keep what’s in your stomach from flowing back into your esophagus.
Stomach. After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine.
Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine.
Large intestine. Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum.
Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement
Answer:
The term “epigenetics” was introduced in 1942 by embryologist Conrad Waddington, who, relating it to the 17th century concept of “epigenesis”, defined it as the complex of developmental processes between the genotype and phenotype.
Explanation:
Alkaline fluid that contributes 30% of semen and provides for the sperm to be active in a protective alkaline environment so that the sperm could move about freely inside the female genital tract
a) RR red BB Blue and RB purple are the genotypes of flower colour in incomplete dominance.
b) 0% probability
c) There is 100% probability of purple colour flowers
d) 0% probability
Explanation:
a)If a poofkin with red flower is crossed with blue flowers:
Alleles for red colour RR
Alleles for blue colour BB
By Punnett square:
R R
B RB RB
B RB RB
b) genotype of red flower = no red flower hence 0% probability
c) probability of purple flowers = 100%
d) probability of blue flowers = 0% probability
The incomplete dominance is a phenomenon in which both the genotypes are expressed in the phenotype of the progeny. It occurs when both the alleles of the gene are dominant over each other resulting into intermediate characteristic. The heterozygous progeny will be the intermediate in phenotypic characters.
