Buffers in our blood are able to neutralize changes in the bloods pH.
Answer:
The endosymbiotic theory states that chloroplast originated from A Cyanobacteria entering and remaining in the cytoplasm of another cell.
Explanation:
Endosymbiotic theory in an important theory of evolution which states that Eukaryotic cells are originated from prokaryotic organism.
The theory deals with the fact that chloroplast and mitocondria were free living prokaryotic organism at Past. The similarities between prokaryotic cell and these Eukaryotic organelles(Mitocondria,Chloroplast) and the evolution of mitocondria and chloroplast from the prokaryotic cells is best exlained by the theory of endosymbiosis.
Mitocondria evolved from the Endocytosis of aerobic bacteria,whereas Choroplast are originated from photosynthetic bacteria such as cyanobacteria.
Answer:
Toxic waste
Explanation:
Toxic waste are chemical substances which are poisonous, can cause cancer, can cause birth defects and may lead death or severe ailment. Toxic waste can lead to poisoning occurs when ingested, inhaled, or absorbed by the skin.
Examples of toxic wastes are Lead-Acid Battery, Mercury (mercury pollution), Pesticides Pollution, Arsenic in Ground Water etc.
Mercury vapors can cause neurological and behavioral disorders like tremors, emotional instability, insomnia, memory loss and so on.
Answer:
Matthias Schleiden, Theodor Schwann, and Rudolf Virchow are the contributors of cell theory.
Explanation:
Matthias Schleiden and Theodor Schwann formulated the cell theory in 1839 after studying tissues. They said that cell is the basic unit of life, new cells are formed from the old cells through cell division and all living things are made up of one or more cells. Matthias Schleiden, Theodor Schwann, and Rudolf Virchow are the three scientists who made important contribution to cell theory.
Answer: (A) Genetic drift
Explanation:
The genetic drift is one of the process of random sampling in which the existent gene frequency are get changed in the organisms and it is also refers as the allelic effect.
According to the given question, In a small remote area the different types of people are living and in that area the "Blue skin" condition is highly incidence due to the variation in the hemoglobin structure.
So, the high frequency in the Blue skin in that specific area is one of the example of the genetic drift and the main role of the genetic drift is to determining the sampling error from the different generation gene.
Therefore, Option (A) is correct answer.
