Biology MCQs

Notes:
In liver Simple sugars (monosaccharides) which are in excess are converted into complex polysaccharides like glycogen

Notes:
Helophyte are those plants which are typical of marshy or lake-edge environments, in which the perennating organ lies in soil or mud below the water level, but the aerial shoots protrude above the water for air.

Notes:
The protein responsible for the maintenance of osmotic pressure in the blood is albumin. Albumin, produced by the liver, constitutes about 60% of the total protein in plasma and plays a crucial role in regulating oncotic pressure, which helps retain fluid within the blood vessels. Low levels of albumin can lead to edema and other complications. In contrast, beta macroglobulin and gamma globulin (immunoglobulins) are involved in immune responses and do not primarily function in osmotic pressure regulation.

Notes:
Human papilloma virus (HPV) is a viral infection that’s passed between people through skin-to-skin contact. There are over 100 varieties of HPV. Human Papilloma Virus is 0related to Cervical cancer.

Notes:
Memory loss would most likely be due to a malfunction of the cerebrum. The cerebrum controls all voluntary activities and receives and interprets sensory information. The medulla controls involuntary actions such as breathing. The cerebellum coordinates muscle activity and controls balance. The pons is a mass of nerve fibers running across the surface of the mammalian brain.

Notes:
White-nose syndrome (WNS) is an emergent disease of hibernating bats that has spread from the north-eastern to the central United States at an alarming rate.

Notes:
The axillary bud is a bud that develops in the axil of a leaf of a plant (synonymous with lateral bud). Axillary buds develop from the nodes which then becomes a new stem.

Notes:
Lactobacillus Bacteria in Milk changes Milk to Curd. When milk is heated to a temperature of 30-40 degrees centigrade and a small amount of old curd added to it, the lactobacillus in that curd sample gets activated and multiplies. These convert the lactose into lactic acid.

Notes:
Iron is also found in many plant-based foods such as:
• Green vegetables, for example spinach, silverbeet and broccoli
• Lentils and beans
• Nuts and seeds
• Grains, for example whole wheat, brown rice and fortified breakfast cereals
• Dried fruit

Notes:
• If you are colorblind, you have difficulty distinguishing certain colors, such as blue and yellow or red and green. Color blindness is an inherited condition that affects males more frequently than females
• Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern. The genes associated with these conditions are located on the X chromosome, which is one of the two sex chromosomes. In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disorder.
• Sickle cell anemia is inherited as an autosomal recessive condition. This means that the gene can be passed on from a parent carrying it to male and female children.
