Control is something that remains the same or constant through an experiment. And an experiment group is the group you test the one change on. (Also called the dependent variable)
Answer:
An emulsifying agent is typically characterized by having <u><em>d. one polar end and one nonpolar end.</em></u>
Explanation:
Emulsifiers are substances that have the ability to bind, for example, fats with those substances that have mostly water in their conformation. In other words, the emulsifier facilitates mixtures of two or more immiscible liquid substances.
This is because the molecules of an emulsifier are often lipophilic (attract oil) at one end and hydrophilic (attract water) at the other. In other words it consists of a polar (hydrophilic) head group and a non-polar (hydrophobic) tail.
<u><em>An emulsifying agent is typically characterized by having d. one polar end and one nonpolar end.</em></u>
Answer:
The total pressure is 724 mmHg
Explanation:
If you want to know the total pressure of the mixture, you must sum each partial pressure.
555 mmHg + 149 mmHg + 13 mmHg + 7 mmHg = 724 mmHg
<span>They both produce eggs inside of shells, which contain the developing offspring.</span>
After mating, the females of both groups produce eggs which envelope, nourish, and protect the developing offspring until they are ready to hatch. This is an adaptation that allows these groups to live their entire lives on land without having to return to the water in order to reproduce the way amphibians do.
All birds and most reptiles are oviparous, meaning that they lay their eggs outside of their bodies, in which the offspring develop until they hatch.
Some snakes are ovoviviparous, which means that after the mother produces the eggs, she retains the eggs until they hatch and she gives birth to live young. This is not the same as female mammals in which there is a uterus, an embryo, an amniotic sac, and a placenta.
