Answer:
R1 and R2 exhibit codominance.
Explanation:
In the given plant, pleiotropic locus regulates both berry color and berry size. The R1 allele gives red berries while the R0 allele is responsible for white berries. The heterozygote R0R1 also has red berries, which means that R1 is dominant over R0 for the color of berries. The R2 allele is responsible for the "small" size of berries in homozygous genotype.
The genotype R0R2 also has small berries, which means that R2 is also dominant to R0. However, the genotype R1R2 imparts red color and small size to berries. In the genotype R1R2, both the R1 (responsible for the red color of berries) and R2 (responsible for the small size of berries) alleles are expressed. This represents the fact that the R1 and R2 alleles are codominant and express themselves in heterozygous R1R2 genotype.
Just before mitosis occur in a stage known as Interphase the cell grows and makes copies of its genetic material in preparation for the cell's division into two identical cells. Therefore, option (C) is correct.
In the study of cell biology, the phase of the cell cycle known as mitosis is the stage at which replicated chromosomes are partitioned into two new nuclei. Mitosis is a method of cell division that results in the production of cells that are genetically similar and in which the total number of chromosomes is preserved. Since this occurs during mitosis, the process is often referred to as equational division.
Conventionally, the process of mitosis is broken down into five stages that are referred to as prophase, prometaphase, metaphase, anaphase, and telophase.

Answer:
The correct answer will be option-
1. Liquid portion of blood- blood plasma.
2. RBC- erythrocytes.
3. WBC- leukocytes.
4. Cell fragments- platelets.
5. Process- hematopoiesis.
Explanation:
The blood is the connective tissue present in the body which connects the two or more systems of the body.The centrifugation of blood showed that the blood is composed of liquid and solid particles as the liquid portion is suspended in the supernatant while the solid particles are present in the pellets.
The liquid portion of the blood is known as blood plasma while the solid portion is composed of three types pf cell: the red blood cell (erythrocytes), white blood cells (leukocytes) and the platelets. All these cells perform different functions like RBC helps in the transport of oxygen, WBC provides immunity to the cell and platelets helps in clotting of the blood.
These blood cells are formed in adults in bone marrow through hematopoiesis from the stem cells presents in the marrow.
Thus, the options are correct.
The liquid portion of blood is plasma, making up about 55% of it's volume. The remaining consists of erythrocytes (red blood cells), leukocytes (white blood cells), and platelets which clot blood. These elements are developed in the bone marrow through a process called hematopoiesis.
The liquid portion of the blood is called plasma and makes up about 55% of the blood volume. The rest of the blood is made up of what's known as the formed elements. These consist of the erythrocytes (another word for red blood cells) and the leukocytes (another word for white blood cells) and cell fragments called platelets which are responsible for clotting. All the blood cells are developed in the bone marrow through a process called hematopoiesis.

In the digestive tract, mouth is the primary location where enzymes act to break the bonds between disaccharides into monosaccharides.
It consists of the gastrointestinal tract along with the accessory organs which are present in digestion process . It involves the breakdown of complex food into smaller components which can be easily assimilated and absorbed by the body.
The digestion process has 3 phases: cephalic phase , gastric phase and intestinal phase.Cephalic phase begins with secretion of gastric juices from gastric glands in response to sight and smell of food.It involves chewing and chemical breakdown of food by the action of digestive enzymes ,saliva in the mouth contain enzymes like lipase and amylase which are secreted by the salivary and serous glands present on the tongue.

Answer:
Mouth.
Explanation:
Mouth contain saliva.Saliva have enzyme salivary amylase (ptyline) which breakdown disaccharides(starch) into Monoscchrides .About 30% disaccharides(starch ) digeation occur in mouth.
