2.2 A learner gives you a rather expensive cycad in a pot for your birthday. The class monitored and documented its growth throughout Term 3. You decided to leave it outside your classroom during the school holidays but found it dead when you returned to school. Explain to your class why this might have happened. (5)
Cycads are an group of vascular plants that are ancient and were prominent components of the world's flora. As the cycad should not be kept dry, leaving it outside the classroom during holiday and not watering properly was the main reason behind the loss of that cycad.
What are the conditions in which a cycad can grow well?Cycads usually prefer warm, moist environments in full sun for survival. As some species are also adapted to dry arid areas, with less winter rainfall.
With respect to the soil, Cycads can tolerate most garden soils with the addition of compost and organic matter, till they are well-watered.
As the cycad was left in the classroom during the school holidays and was not watered and given compost properly, it was found dead.
Thus, watering and composting was the main reason behind the loss of that expensive cycad.

identify the different forms that water takes as altitude increases. (surface to the upper troposphere)
At sea level water occur in natural liquid form in seas, lakes, rivers, waterfall. Water can be salty or freshwater.
What is troposphere?The layer of the atmosphere closest to the earth is the troposphere. This layer is where weather occurs. It starts at the surface of the earth and extends out to about 4- 12 miles. The temperature of the troposphere decreases with height. This layer is known as the lower atmosphere.
As the altitude increases water changes its form as on the mountains where temperature is very low, exist in snow form. As the more height increases, the water changes into water vapour. In stratosphere water changes into gaseous form called as clouds.

What is genotype?Genotype is the genetic representation of an individual.
A blood genotype indicates the genetic composition of the blood type of an individual.
Blood genotype represents the following phenotype:
IAIA or IAi as blood group AIBIB or IBi as blood group B.IAIB as blood group AB.ii as blood group O.Thus, according to the given scenario, the genotype of mother is IAIA and father is IBi, so the phenotypes will be A and B respectively.

how can the process melting and cooling of magma affect the rock cycle
Answer:
Lava eruptions can be “fire fountains” of liquid rock or thick, slow-moving rivers of molten material. Lava cools to form volcanic rock as well as volcanic glass. Magma can also extrude into Earth's atmosphere as part of a violent volcanic explosion. This magma solidifies in the air to form volcanic rock called tephra.
