Answer:
Explanation:
Cancer is a disease of uncontrolled cellular growth. Your body has many mechanisms in place to prevent a cell from dividing uncontrollably. But when the DNA of a cell is mutated, the proteins that govern cell cycle activity can be changed, and a cell may be able to circumvent the body's mechanisms
Answer:

D. 6
E. 2
F. 1
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.
The pollen grain is actually the male gametophyte generation of seed plants. Inside the anther, pollen mother cells divide by meiosis to form pollen grains whose nuclei contain half the number of chromosomes characteristic of the parent plant.
(hope that helped answer the question)
Answer:
Sulfur, phosphorous.... sedimentary cycle.
Carbon, oxygen and nitrogen.... gaseous cycle
Answer:
4778.4 cm³
Explanation:
The formulae of finding the volume of a cone = 1/3 * π * r² * h
(r = radius; h = height)
Therefore replacing the variable with values gives = 1/3 * π * 13² * 27
= 4,778.3624261100755157016805859681
Volume to the nearest tenth = 4778.4 cm³
