Wilts, wood rot, sooty molds, rusts, and smuts. These are all types of plant diseases caused by Fungi. For example, dry rot is a wood decay caused by certain species of fungi that digest parts of the wood which give the wood stiffness and strength. All of them are plant diseases caused by fungi.
Carbon is the main atom used in the formation of molecules that build cells using the DNA based reproduction system. The carbon atom have affinity to bond to other atoms, and is widely available in Nature and is a stable atom.
Carbon forms four bonds in a tetrahedral arrangement around the carbon. This allows a carbon to bond to carbon or other elements with a great variety of shapes. 99% of the mass of a living organism, such as a human, is made up of just six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus with carbon making up the linking element between all others.
Carbon can from a chain that is linear or branched or form ring structures as well as bonding with other functional groups containing other elements from the periodic table.
Neither matter or energy is created or destroyed, it is simply reused.
Answer:
1. B, D and J.
2. A and C.
3. E, F, G, H, AND I.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
A membrane is a thin layer which forms the wall of the cell and typically controls what leaves and enters the cell.
Some of the effects of various biological conditions on membrane physiology are;
1. Makes RMP (Resting Membrane Potential) Less Negative: this simply means that it decreases RMP;
- Decreased concentration of leaky potassium channels in the membrane.
- ATP stores are declining through mitochondrial poison (arsenic).
- Increased concentration of leaky sodium channels in the membrane.
2. Influences the Ability of the Cell to Repolarize;
- Voltage regulated potassium channels are blocked.
- Acetylcholine esterase concentration is decreased.
3. Influences the Ability of the Cell to Depolarize;
- The size of the synaptic cleft is increased.
- Hyperhydration (high water concentration in ECF).
- Release of excitatory neurotransmitter by a presynaptic input is blocked.
- Hyponatremia (low ECF sodium).
- Neurotransmitter synthesis is compromised due to Golgi dysfunction in the presynaptic neuron.
