Answer:
Point A - Intrusive igneous rock
Point B - Extrusive igneous rock
Explanation:
Intrusive igneous rocks are rocks which is formed by molten magma that cools and solidifies below and within the surface of the earth, thereby forming large crystals beneath the earth surface. Examples of Instrusive igneous rocks gabbro, granite, peridotite etc.
Intrusive Ignoeus rock is formed at point A in the diagram given above.
Extrusive Ignoeus rock, on the other hand, is the opposite of Intrusive igneous rock. Extrusive igneous rock is formed when molten rocks, called magma, erupts from beneath the earth and cools and solidifies on the surface of the earth, thereby forming small crystallized rocks. Examples of extrusive igneous rocks are basalt, pumice, etc.
Extrusive Ignoeus rocks would formed at point B in the diagram above.
Answer:
Answer is B. It did not reflect the actual evolutionary relationships among organisms very well.
Explanation:
The five-kingdom system of classification was initiated or formed by Robert H. Whittaker in 1969. And it involved the Kingdoms monera, fungi, protista, animalia and plantae.
This classification system was regarded as not so good because of placement of some certain organisms. For example, in the classification system, unicellular algae were put under the kingdom protista, when other multicellular organisms like algae were being classified under the kingdom Plantae.
The biodiversity will decrease due to an increase in pollution is the effect will have on the biodiversity on the river ecosystem.
Option A
<u>Explanation:</u>
Biodiversity is the actual collection of total amounts of flora and fauna present in a particular ecosystem. The river ecosystem consists of the aquatic plants, the aquatic animals like fishes,etc and even the surrounding land plants and animals, who utilize the river water for their living.
The inclusion of the polluted sewage of the surrounding area into the river directly mixes several chemicals to the water, which are potentially harmful for all the animals living there. This leads to destruction of the flora and fauna of both water and lands surrounding them. This hampers the biodiversity of the water as well as surrounding land.
