Answer:
I believe it's c I could be wrong but I'm pretty sure
Answer:
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. Figure below shows the hands of several different mammals. They all have the same basic pattern of bones
Answer:
Explanation:
This question is a practical question and would require some sort of experiment. However, let's define what rate of reaction means. The rate of a chemical reaction (in this case fermentation) can be described as the speed at which the reaction occurs; meaning the speed at which product is formed per unit time.
The "claim" in the attachment in the question can be referred to as hypothesis since this question is an experiment. The null hypothesis here will be "<u>the rate of alcoholic fermentation is not affected by the type of sugar used as an energy source</u>".
The "evidence" from the attachment will be result of the experiment conducted which cannot be provided here.
However, the conclusion of this experiment (which also answers the main question; does the rate of alcoholic fermentation differ when different types of sugar are used as a source of energy?) should show that the rate of alcoholic fermentation should differ based on the type of sugar used. This is because different enzymes are responsible for the conversion of this disaccharide to the glucose monosaccharide which is what finally undergoes alcoholic fermentation. For example sucrose is broken down into glucose and fructose by sucrase while lactose is broken down into glucose and galactose by the enzyme lactase.
Note that the reaction rate from glucose to produce CO₂ (a product of fermentation) will be the same (regardless of source) but the reaction time from the disaccharide to glucose will be different because of the difference in enzyme and can also be determined by comparing the time to produce the CO₂ by the sugars and the time to produce same amount of CO₂ when given water in the experiment .
Answer:
Endoplasmic reticulum
Explanation:
Endoplasmic reticulum is known to be a site where many cellular components are synthesized and also, it is found to be internal membrane of the eukaryotes. Thus, endoplasmic reticulum exists in two forms which include rough and smooth endoplasmic reticulum. Furthermore, it perform important role in the synthesis of lipids and modification of proteins.
A. Solar energy drives both weather and the water cycle.
