Answer:
Some people offer more prejudice on the sexual orientation because sexual orientation like gay marriages were not seen in the world before. Before the 21st century, the same- sex marriage was never seen or heard about. So, today people display more prejudice regarding this issue because sexual orientation began in the 21st century. Many people are of the view that this same sex marriage is not traditional and hence it is not right morally. While others believe that every person has the right of freedom and this is their civil right to do what they like.
The discrimination based on race and gender has been an issue from the start of human lives. Almost every country has a history which shows race and gender discrimination. Hence, though majority of the people today are against this but still is is not as a hot and new topic for prejudice as the topic of sexual orientation is.
The similarities between bones of humans and other animals shows that every living creature on earth has a common ancestor, even if that common ancestor is as simple as a sing-celled organism.
Answer:
The leaf discs only float in bicarbonate solution and in the light environment.
Explanation:
The bicarbonate dissolves in water to produce a source of inorganic CO2 in the reaction:
NaHCO3 + H2O → H2CO3 + OH- + Na+
Then, the HCO3- undergoes fixation through several complex steps in order to form a carbohydrate or sugar. These store the converted solar energy in their bonds as chemical energy to be used in metabolism.
Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. Energy in the form of glucose molecules is derived from solar or light energy, water, and inorganic carbon dioxide, while it releases oxygen (from the light reaction). The leaf discs float as O2 gas is produced, making them buoyant.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen
Answer:
Answer is B. Positive feedback regulation can generate an abrupt, all-or-none response in which the cell moves from ignoring a signal to responding to it very strongly.
Explanation:
Positive feedback can be described as an example of feedback, which is a natural mechanism that amplifies the action of a system.
It can be better be explained further, as a situation whereby the blood pressure decreases and the response of the body also makes or causes the blood pressure to decrease the more.
Other examples of a positive feedback also include blood clotting, ripening of fruits , uterus muscle contraction, resulting to the stretching of the uterus during pregnancy.
Therefore they are consider matter. Remember anything with a mass is matter.
