The organ that produces clotting factors and albumin is the:
A. Kidney
B. Pancreas
C. Spleen
D. Liver
Answer: Option D
Solution (By JKExamLibrary)
The liver synthesizes most plasma proteins, including albumin (osmotic pressure) and clotting factors (I, II, VII, IX, X). The kidneys produce erythropoietin and active vitamin D, pancreas digestive enzymes, spleen filters.
Explanation:
Secretin is released from the duodenum when acidic chyme enters, stimulating the pancreas to secrete bicarbonate-rich fluid, neutralizing the acid.
Explanation:
Louis Pasteur developed the first rabies vaccine in 1885, using dried spinal cords from infected rabbits. Jenner developed smallpox vaccine, Koch identified tuberculosis bacterium, Salk developed inactivated polio vaccine.
Consider statements about genetics: 1. A gene is a segment of DNA that codes for a protein. 2. Alleles are alternative forms of a gene. 3. The phenotype is the genetic makeup of an organism. Which are correct?
Explanation:
A gene is a specific sequence of nucleotides in DNA that serves as the fundamental unit of heredity, typically coding for a specific protein or RNA molecule. Alleles are different versions or alternative forms of the same gene that occupy the same locus on homologous chromosomes and determine variations in a trait. The genotype is the genetic makeup of an organism, while the phenotype is the observable physical or biochemical characteristics. Thus, statements 1 and 2 are correct.
