The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication.

What is the sequence the organs that are involved in each step of digestion

Cloud [144]

Answer:

The gastrointestinal tract comprises of Mouth-Esophagus-Stomach-Small intestine-Colon-Rectum.

Liver, pancreas and gallbladder are solid organs of digestive system.

Explanation:

Digestion is the process involved in the conversion of large complex food molecules into smaller nutrients that can be used by body cells for survival and carry out their function. The digestive system comprises of various subsequent organs that digest the food.

Digestion starts in mouth where salivary glands digest the carbohydrates.
The food moves from mouth to stomach through alimentary canal known as esophagus. It includes peristalsis movements.
The stomach mixes the food with digestive juices and move the chyme to small intestine.
The small intestine mixes the food with juices secreted from pancreas, liver and intestine and pass it to large intestine.
The large intestine digest the water content from indigested food and pass the reamining to rectum.
The rectum store the undigested food and excrete it through anus.

Please help!!!! very confused pt 2

Schach [20]

Answer:

If the genotype of the parents are Iᵃi and Iᵇi, then four type of offspring will be produced.The genotype of the offspring are, IᵃIᵇ, Iᵃi,Iᵇi, and ii.

Explanation:

IᵃIᵇ = As the alleles are co-dominant in nature, so both type of alleles are expressed. The blood group will be AB. So, both A and B type of antigen will be found in plasma membrane of RBC.

Iᵃi= In this type of genotype only A type of antigen will be expressed in the membrane of RBC. The blood group will be A type.

Iᵇi= In this type of genotype only B type of antigen will be expressed in the membrane of RBC. The blood group will be B type.

ii= This is a recessive type of genotype. So, no antigen will be found on the membrane of the RBC. And the blood group will be O type.

The offspring's ratio will be 1:1:1:1.
