The correct answers are:
B. Warmer air promotes more evaporation.
D. Humidity refers to the amount of water vapor in the air.
E. Areas with a lot of surface water have higher humidity than drier areas.
The humidity can simply be described as the amount of water vapor in the air. The humidity can vary, and it can be very high in certain place for the whole year, very low at other places for the whole year, or to be changing seasonally.
The areas that have a lot of surface water (the Amazon River Basin) tend to have higher humidity than the places that lack surface water (Sahara Desert). Also, the humidity depends a lot on the temperature of the air. The warmer the air is, the higher the humidity, and vice versa, the colder the air is, the lower the humidity.
Answer:
In Amoeba and Paramoecium, osmoregulation occurs through contractile vacoule. Osmoregulation is a phenomenon in which contractile vacuole plays an important role in maintaining the water balance of the cell. Paramoecium contains two contractile vacuoles which have fixed position.
A- when the atoms covalently bond, the two hydrogens share an electron with the oxygen. As a result, they both acquire the ‘noble gas’ rank of having a full out energy shell (8 valence electrons).
Answer:
If the specific sequence of nitrogenous bases in DNA is changed, this will in turn change the sequence of nitrogenous bases in the mRNA (after transcription). During the process of translation, different amino acids will be incorporated in a different sequence due to the different mRNA codons in the mRNA strand. This would most likely result in a non-functional protein or a different protein with other chemical properties than the one specified in the original DNA sequence.
Asexual reproduction involves only one parent and the offspring is identical to the parent. An example of an organism that reproduces asexually is Archaea or bacteria. Sexual reproduction involves two parents and the offspring's genes are equally contributed by each parent. An example of organisms that reproduce sexually are some land mammals. The chromosomes of a parent and offspring in asexual reproduction are identical and there is no difference in the chromosomes.
