Various reasons why five trained individuals might come up with different readings are - while carrying out an experiment, the accuracy with which each individual perform an experiment varies. The readings in different instruments used while performing an experiment also differs.
There is certain percentage of error that occurs while carrying out an experiment by each of the individual. Physical conditions such as temperature, pressure changes from one place to another where the experiments are being carried out.
Answer:
The gonads are reproductive organs responsible for the production of <u>gametes (sex cells) in their external secretion and in their internal secretion, hormones that exert their action on the organs involved in reproductive function.</u>
Explanation:
Gonads are glands that are part of two body systems: the endocrine system and the reproductive system; and there are two types of gonads: male and female, the first are the testicles and the second the ovaries and both produce steroid hormones (derived from cholesterol) exactly the same as those produced by the cortex of the adrenal glands.
Positive feedback is a control system that sends a signal to ( increase) a response.
Answer: C- glycolysis, krebs cycle, electron transport chain.
Explanation: Glycolysis is a catabolic reaction that comprises of series of steps that breaks down food to give off energy in a form of ATP. Pyruvate is the product of glycolysis together with two ATP molecules. Pyruvate is further broken down by joining the krebs cycle and finally the electron transport chain that transfer electrons using the redox reaction, to reduce NADH to NAD + H and FADH to FAD, creating the final product i.e ATP, Overall one glucose molecule gives 38 ATP molecules in aerobic respiration.
A trait is the organism's feature. So, a trait would be eye color. A phenotype would be hazel. An allele is a gene. It can be recessive or dominant.
