answer: mitosis (M phase)
the cell grows in G1 and G2 stages of the cell cycle
Answer:
- The recoil force of a bazooka (reaction) + the accelerating force of a missile
- When walking, the foot pushes down and back (action) + the floor pushes up and forward
- When a rocket is taking off, the combustion of the fuels (an action) creates a direct and opposite reaction which is the thrust of the rocket upwards.
Explanation:
Newton's third law states that for every action (force) in nature there is an equal and opposite reaction. Simply put, forces act in approximately equal and opposite pairs (Action and Reaction).
This law is one of the reasons why the foundation of a building must be built in such as way that is exerting equal and opposite pressure against the building which it is carrying. When the forces are equal, the balance of forces are said to be in equilibrium.

1. The main aim of the Human Genome Project was to determine the DNA Sequence of every human gene.
2. Variation in skin colour is an example of polygenic inheritance
This Human Karyotype is unusual because it has an extra chromosome at chromosome 21.
Klinefelters syndrome is shown in the second figure
Explanation:
1. The Human Genome Project's main goal was to sequence all the 30,000 genes and 3 million base pairs in their makeup for the early detection of diseases, gene therapy and molecular level studies.
2. Human skin colour is determined by the pigment melanin. The Dominant allele is responsible for dark colours as it produces more melanin. The melanocortin 1 receptor (MC1R) gene and Tyrosinase enzyme codes for the human skin colour. Polygenic inheritance are the traits which are controlled by one or more genes.

<u>The extra chro</u>mosome at the 21st chromosome pairs is called trisomy 21 or Down's Syndrome. It is due to the abnormal cell division/meiosis resulting in an extra X chromosome. This leads to thechanges the in physical development of the individual.
Klinefelter's Syndrome: There are 47 chromosomes and 2 or more X chromosomes in this syndrome of males. The resulting male suffering from Klinefelter would be sterile and have poorly developed testicles.
The answer to this question would be:<span>D. delusions of grandeur.
Characteristics that are unique in schizophrenia is that they have delusion and hallucination. In schizotypal patient, they have a strange idea and behavior. Sometimes they also have an idea of reference. note that the schizotypal is a personality disorder so it is on a different axis than the schizophrenia.</span>
