Question

6. Answer the following- a) Explain the germination of a seed. Support your answer with diagram. b) How many different types of buds does your tongue have? Name them. Draw a diagram to show the location of the buds. c) Describe the structure of a ball and socket joint. What movement does such a joint allow? d) How is petroleum formed? Write three uses of it.​

Answer 1

a)Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. Under proper conditions,like appropriate amount of water soil and warmth

Answer 2

Answer:

1.

Step 1: Imbibition: water fills the seed.

Step 2: The water activates enzymes that begin the plant's growth.

Step 3: The seed grows a root to access water underground.

Step 4: The seed grows shoots that grow towards the sun.

Step 5: The shoots grow leaves and begin photomorphogenesis.

Circumvallate taste buds papillae: They are inverted V-shaped, larger and more complex, and are located in the posterior one-third of the tongue look up an Image

3. The ball and socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. The distal bone is capable of motion around an indefinite number of axes, which have one common center. It allows movement in all directions

4. After water, petroleum is another liquid that humans are most dependent upon. It is a source of fuel and is mostly found in many consumer products. As such we will look at some points about this chemical substance in this page. To begin with, petroleum is a naturally occurring element which is in liquid state. It is either yellow or black. It is usually found in geological formations underneath the earth’s crust.

Talking about the composition, petroleum is a mix of thousands of molecules and organic compounds. However, hydrocarbons of various molecular weights form the majority of them.

Petroleum products include transportation fuels, fuel oils for heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials that are in nearly everything we use.
