QUESTION 1 1.1. Scientist designed an experiment to investigate the water holding capacity of sand, loam and clay soil. Soil samples from these soil types were placed in funnels lined with filter paper. 100m of water was added to ALL three soil samples at exactly the same time. The filtrates were collected in measuring cylinders. The results are shown in the following table. Volume of filtrate (in cm”) Time (in minutes) Loam Clay 0 2 4 6 8 10 20 40 60 Sand 10 20 35 50 65 75 10 20 35 45 55 60 65 0 5 10 12 14 16 75 75 (3) 1.1.1. State a possible hypothesis for this experiment. 1.1.2. Identify: (a) the dependent factor (b) any TWO fixed variables 1.1.3. Which type of soil will be most suitable for gardening? Motivate your answer. (3) [093​

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
