Answer:
In the freshwater food web,
the relationship between the minnow and the water fleas can be described as <u><em> Predator-prey relationship</em></u>
Explanation:
A food web can be described as a diagram which shows multiple food chains. It represents the 'predator-prey' relationship in an ecosystem.
The freshwater food web will described all the predator-prey relationships in the fresh water.
The minnows in the fresh water feed on larval fishes, mosquito larvae and water fleas. Hence, minnows will be the predators and water fleas will be the preys. So, these organisms will show a predator-prey relationship.
EcosystemTropical Savanna is found between sections of tropical rain forest and deserts. They have 2 seasons; wet (constant humidity) and dry (long periods of dry spells and drought that may cause fires).
Both savanna buffalo and forest buffalo live close to water. The buffalo are found throughout the northern and southern savanna as well
as the lowland rain forest.
<span>How might this population suddenly increase? How might this affect the ecosystem? If there was an increase in population; grasslands during the wet season will be gone, more predators will flock for an abundance of buffalo.
</span>
<span>What might happen to the ecosystem if this population was removed? If you remove the buffalo from the savanna ecosystem, it can cause a ripple effect such as populations of small mammal (mouse) will double, which will attract more snakes (venomous), it can cause the flea and tick population to increase, and the increase in tick/fleas can cause the risk of transmission of flea/tick borne pathogens.</span>
Answer:
Multiple Sclerosis is an inflammatory disease in which myelin sheath of nerve cells of brain and spinal cord are damaged.
Explanation:
Cause:- (Exact cause of inflammation is not known)
- But damage is caused due to attack by autoimmune cells or antibodies against myelin sheath.
Types of tissues attack:-
- Oligodendrocytes and myelin sheath is damaged and stripped away from axon and the process is known as demyelination.
- Myelin sheaths are made up of fatty tissues and help in transmission of electric impulse.
Result of immune system attack:-
- Damaged myelin sheath stop forming whIte matter of central nervous system.
- Hence disrupt coordinating communication between different brain regions.
Signs and symptoms:- vary from person to person
- Diminished eyesight.
- Disrupt motor coordination.
- Weak sensory perception.
- Fatigue and dizziness.
- Speech disorder.
- Muscle weakness and spasticity.
- Difficulty in urination and stool.
Diagnosis and treatment:-
- Diagnosis include MRI T2 findings and cerebrospinal fluid specific oligoclonal bands.
