One summer you begin noticing ants in your kitchen. It starts off as just a few here and there, but pretty soon you begin notici

ng more and more appearing each day. Before long, it is apparent you have an ant infestation. While you wait for an exterminator to come to your house, you observe their behaviours. You notice that some ants seem to be congregating near crumbs, while other ants seem to avoid the crumbs and, instead, are eating the plant you have in the kitchen. You try to clear the ants away from the food, and when you do, you notice a strong, unpleasant scent. You then try to clear the ants away from the plants, and when you do, you observe no unpleasant odors. When the exterminator arrives, you ask him about these strange observances. Upon closer look at the ants, the exterminator concludes that you have an infestation of two different species, Crematogaster ashmeadi (acrobat ants) and Linepithema humile (Argentine ants). a) Propose the most probable type of speciation that occured between C. ashmeadi and L. humile. Justify your response. b) Identify one potential postzygotic isolating mechanism that reduces the fitness of the hybrid individuals.

Answer:

Sympatric speciation.

Explanation:

Sympatric speciation occurs between Crematogaster ashmeadi and Linepithema humile ants because they live on the same geographical location. Sympatric speciation is a type of speciation in which ancestral population evolve into separate species without separation of geography. Hybrid sterility is the postzygotic isolating mechanism that decreases the fitness of the hybrid individuals and helps in controlling the population of an organisms..

mariarad [96]

Answer:

The two types of lipoproteins are low density lipoprotein and high density lipoproteins

Explanation: As applying to low density lipoproteins (LDL), these are sometimes called the bad cholesterol because a high LDL level leads to a build up of cholesterol in the arteries. This condition narrows the arteries and increases the risk of heart attack, Strom and peripheral artery diseases.

High Density Lipoproteins (HDL), also known as the good cholesterol acts as a scavenger carrying LDL away from the arteries and back to the liver where the LDL is break down and passed from the body.

Consider a population of wildflowers in which the frequency of the red allele cr is p = 0.7. what is the frequency of the white
anygoal [31]
I) Alleles is the alternative form of a gene or in other terms the variant form of a gene. If there are two alleles at a locus p and q are used to represent their frequencies. Frequencies of all alleles in a population will add up to 1. 
Therefore, in this case if red allele CW is p=0.7, then the frequency of the white allele in this population (q) is 0.3.

ii) From the punnet square the expected genotypes frequencies in the offspring generation will be 0.49 CRCR (red flowers, o.42 CRCW (pink flowers) and 0.09 CWCW (white flowers).
