Landforms Shaped by Water and Tectonic Forces
Landforms Shaped by Water Erosion
On hillsides or slopes, this model is given by wild waters or streams. Wild waters or streams occur on very steep slopes where there is little vegetation. The action of these waters gives modeled as fairy chimneys, gullies, or furrows on the earth.
Floods, in contrast, although there are also just as wild waters when it rains or snowmelt, have a channel that is divided into:
- Catchment area: Usually a lot of small grooves that carry the water.
- Drainage channel: Collects
Motherboard Expansion Slots and RAM Types
Motherboard Expansion Slots
Expansion slots on motherboards allow additional components, such as video cards, sound cards, or network cards, to be added to enhance the computer’s functionality. These slots vary in type and capacity depending on the motherboard’s design and format (e.g., full ATX or micro-ATX). Common types of expansion slots include:
- ISA (Industry Standard Architecture): Older 8 or 16-bit slots used primarily before 1997, often black and with two parts (shorter and longer). Phased
Photosynthesis, Respiration, Reproduction & Stimuli Response
Photosynthesis and Cellular Respiration
1. What is Photosynthesis and Cellular Respiration?
Photosynthesis: It is a process carried out by living organisms, such as plants, algae, and some bacteria, to synthesize organic molecules from inorganic molecules absorbed from the environment, using the sun’s energy. Photosynthesis primarily takes place in the leaves and stems where chlorophyll is present.
Cellular Respiration: It is a process of decomposition of glucose molecules to release energy, which

Telegraphic Speech
Telegraphic speech: The final stage of language acquisition is the telegraphic stage. This stage is named as it is because it is similar to what is seen in a telegram; containing just enough information for the sentence to make sense. This stage contains many three and four word sentences. Sometime during this stage the child begins to see the links between words and objects, and therefore overgeneralization comes in. Some examples of sentences in the telegraphic stage are “Mummy

Cell Structures and Their Functions
Mitochondria: These have a double membrane. The outer membrane is flat, and the inner is folded, forming cristae. Cellular respiration takes place inside.
Ribosomes: Made up of two subunits, ribosomes synthesize cell proteins.
Golgi Apparatus: Stacks of flattened membrane sacs called cisternae, which form vesicles. It processes and packages substances.
Endoplasmic Reticulum: A network of flattened membrane sacs and tubes. It transports proteins and sends them to the
