of the body? 6 choocline glands secretes a hormone that directly affects the metabolic hyroid B) Ovary C) Pituitary D) Pancreas The type of gene mutation that results in the change of a triplet (GAG) in a normal hemoglobin nother triplet (GTG) in sickle-cellhemoglobi n is sertion mutation B)Deletior mutation C)Substitution mutationD)No n-disjunction The ability of carnivores to survive in an ecosystem is dependent on the availability of prey.This be considered as atastrophic factor B ) Abiotic factor C)Edaphic factor D)Biotic factor Which nitrogen base is not found in RNA? uanine B)Uracil C)Thymine D)Adenine Which one of the following cells is formed as a result of meiosis? B) Blood cell C) Muscle cell D ) Egg cell in cell Which one of the following organic molecules has ester bounds in its molecular structure? B) Glycogen C) Amino acid D Cellulose iglyceride

## Step1<br />The first question is about the gland that secretes a hormone that directly affects the metabolic rate of the body. The thyroid gland is known for this function.<br /><br />## Step2<br />The second question is about the type of gene mutation that results in the change of a triplet (GAG) in a normal hemoglobin to another triplet (GTG) in sickle-cell hemoglobin. This is a substitution mutation, where one base is replaced by another.<br /><br />## Step3<br />The third question is about the ability of carnivores to survive in an ecosystem, which is dependent on the availability of prey. This is a biotic factor, as it involves living organisms.<br /><br />## Step4<br />The fourth question is about the nitrogen base that is not found in RNA. Thymine is not found in RNA, it is replaced by Uracil.<br /><br />## Step5<br />The fifth question is about the type of cell that is formed as a result of meiosis. Egg cells are formed as a result of meiosis.<br /><br />## Step6<br />The sixth question is about the organic molecule that has ester bounds in its molecular structure. Triglycerides have ester bounds in their molecular structure.
