What experiment demonstrated the function of proteins that allow diffusion facilitated?
denpristay [2]

The experiment by Peter Agre who discovered the protein Aquaporin demonstrated the function of proteins that allow facilitated diffusion of water.

Explanation:

Aquaporins are water channel proteins that facilitated diffusion of water. Agre was able to prove its function when a frog’s oocytes showed increased water permeability when an unknown protein (membranous) from the RBCs was introduced into them. The oocytes without proteins did not facilitate water diffusion.  

Aquaporins are membranous proteins that belong to larger intrinsic proteins but act as pores on the cellular membranes to facilitate water diffusion.

What is the biological significance of genetic diversity between populations? What is the biological significance of genetic div
mrs_skeptik [129]

Explanation:

<u>A) Genes for traits conferring an advantage to local conditions make microevolution possible.</u>

For example, Galapagos finches show variation in beak sizes and shapes related to their niches and available food source; the finches developed adaptations to their environment. Their specialized beaks allow them to adequately exploit the available resources, by utilizing the more abundant food source.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.  Crossing over, independent assortment, and random fertilization ensure genetic variation.

This variation refers to the genetic characteristics present within a species; they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring an advantage.  

Additionally, natural selection, mutation, genetic drift and gene flow lead to microevolution; over time, this is seen as changes to allelic frequencies within a population

Jamal is asked to write a science essay about molecular forces. He first turns to his science textbook for information. Which is
Arte-miy333 [17]
There are several sources in which one may turn to in order to establish a well-founded idea, information, and knowledge towards a given topic. From this item, books were collectively identified as the first source for Jamal's science essay.

The second one could be the information found in the internet. These information have lately became very accessible considering that one could directly upload/download information. The tricky part here is to identify which sources in the internet are reliable and which are not.
