The first colorimeter is precise, but it is not accurate. It seems to have a zero error of -5.
We can conclude its precision because the readings are closely grouped, but its lack of accuracy is due to its variation from the actual value. Moreover, the variation is consistently of 5 points lower than the actual value, so its zero error may be -5.
The second colorimeter may be referred to as being accurate.
Answer:
The correct answer is : B. Carbon dioxide gas is produced as a by-product of alcohol fermentation but not lactic acid fermentation.
Explanation:
In t5he lactic fermentation, the end product is lactic acid whereas in Alcohol fermentation produces by-product carbon dioxide gas which makes it more suitable for baking.
Alcohol fermentation takes place the bread is made as gas is what puts tiny air bubbles within the dough of the bread and makes bread lighter consistency we are used to. Yeast helps in producing carbon dioxide by alcohol fermentation.
The correct answer is option (A) the fossil record.
Coordinated stasis refers to the stasis or the no evolutionary changes in the organisms for millions of years, which is followed by extinction and formation of the new species.
Fossil records have the evidence of ecological and evolutionary stability in the species over a long period of geological time scale separated by intervals of abrupt change. The best example of this being the animals of the Middle Devonian Hamilton group. Thus, fossil record is the only source of record showing this long period of stasis and separated by periods of abrupt changes in the species due to environmental pressures.
Answer:
A.
Explanation:
Meiosis is a form of asexual reproduction.
Chromosomes are found in the nucleus of body cells. These chromosomes are made of protein and deoxyribose, which is a five-carbon sugar. Some of these chromosomes can be found in the mitochondria of a cell also. Hope this helps!
