C. 5
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.
Answer:
The correct answer will be option-B
Explanation:
The data collected on the bacterial species in the Yellowstone national park involved:
1. habitat characteristics
2.DNA of bacteria from each population
3. compared with other species of the park
Based on these features, the biologist could apply all the types of species concept like ecological species concept which allows the study of the species from the same niche.
Also, they compared the DNA of the species of the bacteria and compared them which allows to trace the evolutionary patterns and showing the phylogenetic relationship.
Since bacteria do not reproduce by the sexual reproduction, therefore, a biologist cannot apply the biological species concept which states that species can be called species which can reproduce only with the closely rated species only or the individual of the same species.
Thus, Option-B is the correct answer.
Answer:
Collaborative empiricism
