The correct option is A.
A basic solution has a high concentration of hydroxide ions more than any type of ion and that is why it is basic in nature. An acidic solution has a higher concentration of hydrogen ions and that is why it is acidic in nature. A neutral solution has equal amount of hydroxide and hydrogen ions. Solutions are usually classified as either basic or acidic based on their hydrogen ion concentration.
Answer: Option (C)
Explanation: The rocks at the continental crust are present since a long time, and the oldest rocks so far encountered from the continental crust is approximately 4.4 billion years old.
This has been determined by the Uranium-Lead dating method (Ur₂₃₈-Pb₂₀₆).
Oceanic rocks are estimated to be of very recent age i.e about only 180 million years old.
Answer:
How do punnet squares allow you to predict how traits are passed from one generation to the next?
This is simply achieved by crossing which enable each gene of both parents to be paired with one another
Explanation:
Option (B) Interdependent is the correct answer.
How do organisms live in an ecosystem?
An ecosystem comprises two components ie. living and non-living. Living components include all the organisms such as animals, humans, plants, etc., and nonliving components include soil, air, water, etc. All the organisms which live in the same ecosystem are interdependent, as well as dependent on nonliving components too. This is called interdependence.
They are dependent on each other for food, shelter, pollination, seed dispersal, etc.
The food chains and food webs are the most important example of interdependence shown by organisms living in an ecosystem.
