Photosynthesis Factors: Temperature, Light, and CO2 Impact
Photosynthesis: Factors Affecting the Rate
Temperature
- At low temperatures, the rate of photosynthesis is very low.
- Photosynthesis requires enzymes. As the temperature increases, the kinetic energy of the reactants increases, thereby increasing the rate of photosynthesis.
- This rate increases until an optimum temperature is reached. In plants, this optimum temperature is usually between 25°C and 35°C.
- After the optimum temperature is reached, the rate of photosynthesis drops dramatically because the

The Neuron: The Building Block of the Nervous System
A neuron is the fundamental cell of nervous tissue.
Neuron Components:
- Cell Body (Soma): Located around the nucleus, containing most of the cytoplasm. It generates nerve impulses.
- Dendrites: Short, branching extensions that receive nerve impulses from other neurons.
- Axon: A long, slender extension that transmits nerve impulses away from the cell body to other neurons or effector cells.
Types of Neurons:
- Sensory Neurons: Transmit nerve impulses from sensory

Grasshopper Anatomy: A Detailed Look at Key Structures
Grasshopper Anatomy: Key Structures and Functions
Here’s a detailed breakdown of the grasshopper’s anatomy, covering its key structures and their respective functions:
1. Head
Contains nervous tissue and sensory organs.
2. Thorax
Bears structures associated with movement.
3. Abdomen
Contains reproductive and digestive organs.
4. Clypeus
Delimits the lower margin of the face.
5. Labrum
Protects the delicate mouthparts.
6. Mandibles
Grab and tear food into smaller pieces.
7. Maxillae
Move food particles into the

DNA (Deoxyribonucleic Acid): The genetic material that carries hereditary information. The central dogma of molecular biology is DNA → RNA → Proteins. These proteins, often polypeptides, form structures like enzymes, which participate in the formation and breakdown of biomolecules, including nucleic acids, lipids, carbohydrates, and proteins.
RNA (Ribonucleic Acid): Another type of nucleic acid essential for various biological roles.
Genotype: The genetic information of an organism.
Phenotype:

Mitosis
- Interphase: Visible nucleolus, chromosomes or diffuse chromatin.
- Prophase: Nucleolus disappears. Centrioles and asters appear and separate. The spindle forms, and each chromosome that constitutes two chromatids reappears together by the centromere.
- Metaphase: The nuclear membrane disappears, and the spindle extends to the poles. Chromosomes align on the spindle.
- Anaphase: Each centromere divides. Sister chromatids separate and go to opposite poles. The separated chromatids are now considered
