Answer:
Explanation:
The rock cycle is driven by two forces: (1) Earth's internal heat engine, which moves ... enough to drive mantle convection and there is no atmosphere or liquid water. ... In describing the rock cycle, we can start anywhere we like, although it's ... Referring to the rock cycle (Figure 3.2), list the steps that are necessary to cycle
The researchers will use mice instead of opossums or humans to determine whether the cells of the ear bones originated from the same embryonic cells as the cells that form the jaw in other vertebrates because in this type of experiment, organisms that are ideal are the ones that have a short life span, easy to be researched on and easy to mantain.
It will be very tedious and demanding to use opossums and humans in this type of practical experiment because,it is against the culture and norms guilding human living and existence to use humans as model organisms,opossums as well are very bad model organisms because unlike the mice,opossums are long lived and it will be very difficult to raise and maintain an opossum in a laboratory.
Humans and mice are both mammals just that human is a higher mammal but they share similar features in terms of pattern of development,though there is a clear difference during their early development,so because of the common ancestry shared by the mice and humans,the result of the experiment on the mice with share a close similarity with the pattern that is expected in humans.

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.
1. The centriole forms the pole of the spindle apparatus chromatin
2. The nuclear envelope, also known as the nuclear membrane, is made up of two lipid bilayer membranes which surrounds the nucleus
3. Haploid
4. Chromatids
5.Meiosis
6. Spindle Apparatus
7. Anaphase
8. Mitosis
9. Chromatin
10. Interphase
