Answer:

The most likely explanation for the high rate of sympatric speciation that apparently existed among the cichlids of Lake Victoria in the past is sexual selection.

Explanation:

Divergent sexual and natural selection on the visual system has been confirmed earlier in sympatric, morphologically comparable sister species of Lake Victoria cichlids, but this seems not to reveal the exact morphological variations within them.

Cichlid fish reasonably describe the enormous inventory of standards of speciation and reproductive isolation without geographical or ecological separation.

Most of the recent observations have not confirmed the hypothesis, implying that sexual selection may be effective for the bursting cichlid speciation in the lake. Workroom practices have shown that reproductive isolation of three morphologically comparable species of rock-dwelling cichlid fish.

What is genectic monotony​
Art [367]

Answer:

Genetic monotony is the result of asexual reproduction which generation after generation exactly identical progeny develops.

Explanation:

The process of sexual reproduction involves two parents, each of hem contributing one gamete. Gametes are produced by a process called meiosis, which starts by the duplication of the chromosomes, followed by two rounds of cell divisions and halving of the chromosome number. Gametes have half the chromosome number of other adult cells of an organism.

A tobacco plant is heterozygous for the genes for long stems (Ss), large leaves (Ll), and fibrous roots (Rr). It is crossed with
Ainat [17]
Firstly, start by doing Punnett squares for each of the characteristics. Attached are the three Punnet squares, made by me, as they should look in end.

For each of the Punnet squares, one characteristic each, we find that half of the offspring will be heterozygous for that characteristic.
Therefore, according to the product rule, you should now multiply the quantity of heterozygous for each characteristic and then obtain the total part of the offspring that's fully heterozygous.

\frac{1}{2}Ss×\frac{1}{2}Ll×\frac{1}{2}Rr=\frac{1}{8}SsLlRr

Total offspring×\frac{1}{8}=10
There is 10 plants in the total offspring that are heterozygous for all the considered three genes.

Look at the data related to honey bee population losses between 2006 and 2013 (Figure 1). Expand on the data. How would you revi
olga_2 [115]

In order to improve the graph and make it more detailed in order to get a better perception why the honey bee populations are decreasing, there's few things that can be added.

- Number of bee keepers over the period

The number of the honey bee colonies is directly connected as to how many bee keepers there are. If there's a trend of a decline in the bee keepers, than there will be a trend in the decline of the honey bees.

- Area of trees suitable for the honey bees

The trees are crucial for the honey bees to be able to produce honey, thus it is very important that they have a certain area of trees on which they can feed upon. If there's a decline in the number of trees for the bees, than the bees will be dying from starvation.

- Pollution

The honey bees are animals that are very sensitive to changes in the environment, especially when it comes to pollution. If the levels of pollution are increasing in areas where there's honey bees, it will certainly affect their numbers in a negative manner.

There are 6 molecules of O2.



"O2" is the formula for one molecule oxygen, which has 2 atoms.

The subscript (small) "2" tells you how many atoms are in the molecule.

The coefficient is the big number tells you the number of molecules.

In 6O2, there are 12 atoms in total (6 molecules of 2 atoms each).
