Stem cells have the ability to replace damaged cells and treat disease. ... Stem cells, if they can be directed to differentiate into specific cell types, offer the possibility of a renewable source of replacement cells and tissues to treat diseases including Parkinson's, stroke, heart disease and diabetes.
Answer: The type of inheritance shown by the gene that control sickle cell anaemia is autosomal recessive inheritance
Explanation: Autosomal recessive inheritance means that there is mutation in two copies of the gene in a cell. Sickle cell anaemia is a condition caused by a single point mutation in the two beta chains of haemoglobin. Haemoglobin is a protein in the red blood cells responsible for oxygen transport to the cells. The mutation is caused by substitution of valine in place of glutamate at the sixth position of the two beta chains of haemoglobin.
Every individual has two copies of almost every gene, one from the mother, and one from the father. The autosomal recessive inheritance pattern of sickle cell gene means that for an individual to manifest outwardly as sickle cell, the two copies of the gene inherited from the parents are mutated.
Answer:
Angiosperms group
Explanation:
Angiosperms or commonly referred to as "flowering plants" are the most advanced and diverse group of plants in the Kingdom Plantae. They are a plant group characterized by the possession of a reproductive structure called FlOWERS, which develop into fruit and seeds when fertilized.
Therefore, if Racheal ate a fruit and drop its fruits in the backyard, where she later noticed the growth of a flower-producing plant, it means that plant that Rachel ate is an ANGIOSPERM because it produces FLOWERS. Flower is a distinguishing factor for Angiosperms.
