How would you expect the attenuation of light (like with increased turbidity) to influence net productivity? Why?

olga55 [171]

Having things other than chlorophyll (or bacteriochlorophyll or bacteriorhodopsin) absorbing the light will decrease productivity in any ecosystem whose biotic basis is photoautotrophs.

Is neon different from oxygen?And how is it different? Please explain.

EleoNora [17]

Neon is a member of the noble gas family. Other elements in this family includes helium, argon, krypton, xenon, and radon. These gases are in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The noble gases are sometimes called the inert gases. This name comes from the fact that these elements do not react very readily. In fact, compounds exist for only three noble gases—krypton, radon, and xenon. Chemists have yet to prepare compounds of helium, neon, or argon.

Neon was discovered in 1898 by British chemists William Ramsay (1852-1916) and Morris Travers (1872-1961). It occurs naturally in the atmosphere, but only in very small amounts.

Complete question:

17. In the 1950’s a young woman sued film star/director Charlie Chaplin for parental support of her illegitimate child. Charlie Chaplin’s blood type was already on record as type AB. The mother of the child had type A (AO) and her son had type O blood (OO).

a. Complete a Punnett square for the possible cross of Charlie and the mother.

b. The judge ruled in favor of the mother and ordered Charlie Chaplin to pay child support costs of the child. Was the judge correct in his decision based on blood typing evidence? Explain why or why not. *refer to any Punnett squares to support your answer.

Answer:

The judge committed a mistake in his decision. There are no chances for this couple to have a child who has 0 blood type.

Explanation:

Available data:

Charlie Chaplin’s blood type was AB
The mother of the child had type A (AO)
The son had type O blood (OO).

Cross: Charlie Chaplin x The Woman

Parental) IAIB x IAi

Gametes) IA IB IA i

Punnett square) IA IB

IA IAIA IAIB

i IAi IBi

F1) 1/4 = 25% of the progeny would have IAIA genotype, blood type A

1/4 = 25% of the progeny would have IAi genotype, blood type A

1/4 = 25% of the progeny would have IAIB genotype, blood type AB

1/4 = 25% of the progeny wouldl have IBi genotype, blood type B

According to the results of the cross observed in the Punnett square, there are no chances for this couple to have a child who has 0 blood type.

Blood type 0 can only be produced by two recessive alleles i, one inherited from each parent. The mother could provide the recessive allele because she is IBi, but Chaplin could not pass to his progeny any recessive allele.

The judge committed a mistake in his decision.
