We communicate to outside world with eye contact, hand gestures and nonverbal communication (whistles, whines, screams, etc.). This can be compared to the warning calls made by packs of animals about approaching prey. The world communicates to us in touch (i.e. dog rubbing up against your leg to show affection), gestures (i.e. crossing guard gesturing when to cross the street) and sounds (i.e. train whistle announcing approaching train). Hope this helps!
fossilized tree sap, also known as amber, prevents scavengers, water, and oxygen from getting to the organism and destroying its remains.
Amber is a fossilized tree sap that has been prized since Neolithic times for its color and natural beauty. Amber has long been valued as a gemstone, and it is now used to create a variety of decorative objects. Tree resin is a fluid (Sap) produced by plants (most commonly trees), but it is not the same as sap. Sap is a watery, sweet substance, whereas resin is thicker and stickier. Frankincense, Myrrh, Benzoin, and Copal are examples of well-known resins.

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.
Answer:
Life processes are the series of actions that are essential to determine if an animal is alive. 2. What are the Life Processes? There are seven essential processes in common: movement, respiration, sensitivity, growth, reproduction, excretion and nutrition or MRS GREN.
