Answer:
D (Genotype)
Explanation:
A genotype is the genetic make up of an organism i.e. what the genetic material
of an organism constitutes. Genotype describes the set of genes contained in an organism's genome. According to Mendel, an organism receives two forms of genes called ALLELE for a trait, one from each parent. The genotype of a specific gene coding for a trait is represented by each pair of allele for that trait.
Although the genotype of an organism is outwardly invisible i.e. cannot be seen, but it determines the phenotype of that organism i.e. the outward appearance. For example, if a plant receives T and T alleles coding for tallness, from each parent. The genotype of that plant for the specific height trait will be (TT). Hence, the TT genotype although invisible but controls the tallness of the plant.
Answer:
1. Circulatory System
2. Respiratory System
3. Endocrine System
4. Nervous System
5. Urinary/ Excretory System
Explanation:
1. Circulatory System- The heart pumps blood and blood vessels such as arteries and veins, transports the blood to every part of our body providing organs and muscles with nourishment.
2. Respiratory System- This system maintains our breathing. It supplies the body with oxygen for cellular respiration.
3. Endocrine System- The glands of the endocrine system secrete chemicals called hormones that regulate most of the processes in our bodies like growth, reproduction, metabolism, etc...
4. Nervous System- The entire nervous system controls all of the other systems of the body and it also transmits information to the brain, such as pain and external sensations.
5. Urinary/Excretory System- This system is responsible for eliminating waste products of metabolism and other materials from the body that are of no use.
