The phanerozoic geologic era is divided into three and the paleozoic era is the first among them. The paleozoic era occurred about 902 million years ago and it divided into six different periods. It was a time of dramatic changes in term of climate, geology and evolution.
During the first period of the paleozoic era large number of creatures evolved, this is called Cambrian explosion. Most of the biological classes that are still prevalent today such as primitive fish and coral were evolved during this era. Mass evolution of fish also occured during this era. <span />
Gymnosperm plants important adaptation of the seed allowed plants to spread quickly across the land.
What is a gymnosperm ?
- Unlike angiosperms, or flowering plants, whose seeds are enclosed by fully developed ovaries, or fruits, gymnosperms, or any vascular plant, reproduce by the use of an exposed seed, or ovule.
- Many gymnosperms bear their seeds in cones, which are known as "raw seeds" because they are not visible until they are fully developed.
- Yew ,Gingko biloba, Cycads , Pines, Spruce are examples of gymnosperm
What is adaption in plants?
- Special characteristics that enable a plant or animal to survive in a specific location or habitat are known as adaptations.
- The plant can find it exceedingly challenging to live in a foreign environment because of these adaptations.
- This explains why some plants are only found in particular places.

A high-fiber diet might help decrease blood cholesterol levels by
a) preventing ketosis
b) keeping stools soft
c)trapping cholesterol in pockets in the large intestine
d)Causing fiber to bind with bile and more cholesterol to be excreted
Answer:
Causing fiber to bind with bile and more cholesterol to be excreted
Explanation:
High fiber diet include whole grain cereals, fruits, vegetables, nuts and potatoes etc., when consumed,they bind with cholesterol to aid degeneration in order for excretion to occur. They aid digestion and increase bowel movement, helps the body to lose weight, stay full longer, and improve health.
Answer:
Igneous rock , formed by the cooling of magma (molten rock) inside the Earth or on the surface. Sedimentary rocks, formed from the products of weathering by cementation or precipitation on the Earth's surface. Metamorphic rocks, formed by temperature and pressure changes inside the Earth.
