Study Notes
Asexual Reproduction
- Asexual reproduction involves six types: Binary Fission, Budding, Vegetative, Spores, Fragmentation, and Regeneration.
- Advantages of asexual reproduction: rapid production of offspring, no need to find a partner, and no energy investment.
- Disadvantages of asexual reproduction: lack of genetic diversity, prone to extinction, and no adaptation.
Sexual Reproduction
- Sexual reproduction produces four haploid daughter cells through meiosis.
- Advantages of sexual reproduction: genetic variation, adaptation to new environments, and reduced disease susceptibility.
- Disadvantages of sexual reproduction: higher energy investment, longer development time, and requirement for a partner.
DNA Base Pairing
- Adenine (A) pairs with thymine (T).
- Cytosine (C) pairs with guanine (G).
Electricity
- Static electricity: stationary or accumulated on an object's surface.
- Current electricity: rapid flow through a conductor.
- Resistance (R) measured in Ohms (Ω).
- Potential difference (V) measured in Volts (V).
- Current (I) measured in Amperes (Amps) (A).
- Parallel circuit: multiple pathways for current flow.
- Series circuit: single pathway for current flow.
- Law of attraction: opposite charges attract each other.
- Law of repulsion: same charges repel each other.
- Conductors: materials allowing electrons to move freely.
- Insulators: materials blocking electron flow.
- Open circuit: "off" or not allowing electricity to flow.
- Closed circuit: "on" or allowing electricity to flow.
