Answer:
Chromosome structure consists of a long arm region and a short arm region connected at a central region known as a centromere. The ends of a chromosome are called telomeres. Duplicated or replicated chromosomes have the familiar X-shape and are composed of identical sister chromatids.

Explanation:
1. Integumentary system.
This is an organ system that consists of hair, skin, nails and exocrine glands with receptors that senses the outer stimulus and environmental conditions, through homeostasis maintain stability of the internal environment.
2. Nervous system.
It receives sensory information and signals, convert them to nerve impulses that are transmitted to the body and brain via the spinal cord using nuerons and axons. It also intergrates, retains and analyses information in the brain.
3.Endocrine system.
Secretes hormones and chemicals in response to stimulus from the nervous system to maintain balance using feedback loops i.e, negative and positive.
4. Lymphatic system.
Part of the immune system that consist of vessels that carries lymph, cleaning the blood by filtering lymph with foreign particles into the lymph node.
5. Urinary system.
Used to eliminate waste from the body, regulates blood pressure, volume and pH. It also used to retain electrolytes and metabolites.
6. Respiratory system.
Used for gaseous exchange using the blood, heart and lungs. Air enters the lungs, transported by blood and is pumped by the heart to all body parts where oxygen is dropped, carbon dioxide is collected by the veins to the lungs and released to the atmosphere.

Biologist
study life to the extent to which they can uncover, unearth and investigate unseen,
latent and concealed life forms that are still many in number, these crawling
and under the water creatures. And in experimental sense, many biologists are
guided by the ethics in researching life forms. This is to protect and inhibit
other biologist in killing thousands of these living organisms and prevent them
from becoming extinct. Remember that biologists or any other scientists study
because of knowledge and to contribute to the scientific world of making the
ecosystem including us into a much better and cultured place and not the
opposite.
Hence, there are non-experimental and experimental approaches which
are all subject to ethics. In exploring life forms, it is quite unlimited but
studying life forms in experimental sense, it is somehow depends on the number
of species that the biologists’ study.
