Answer:
maintaning the essential internal parameters relatively constant is the phrase that best describes the process of homeostasis.
Organisms that do not survive or adapt in Hurricane Sandy are seabirds like woodpeckers, shorebirds such as sandpipers, sea mammals like dolphins, creatures that are less salt-water such as crabs, minnows, marsh grasses, fish hatchlings. These are the few examples of the living organisms that were affected when Hurricane Sandy strikes.
The correct answer to this open question is the following.
Although you forgot to include the context of the question and the options to answer it, we can comment based on our knowledge of this topic.
What scientists most likely can expect to find in the layers of rock that are about the same age as the impact is evidence of a gradual change of one species over time.
This question has to have the following context. Scientists found evidence of a large meteor impact on the coast of the Yucatán Peninsula in Mexico.
Scientists, researchers, and geologists use special methods to date rocks and fossils on planet Earth. In this case, they have used a method called radiometric dating. These methods are based on radiation. Yes, they use the natural radioactive decay of potassium, carbon, and other elements to get to the most exact date on when things happened. In this case, the time of the meteor impact on the Yucatán Peninsula in southern México.
Answer:
1. A plant of genotype
is testcrossed to
If the two loci are 10 m.u. apart, what proportion of progeny will be A B/a b?
45 percent of the progeny will be A B/a b
2. The A locus and the D locus are so tightly linked that no recombination is ever observed between them. If A d/A d is crossed to a D/a D, and the F1 is intercrossed, what phenotypes will be seen in the F2 and in what proportions?
P A d/A d × a D/a D
F1 A d/a D
F2 1 A d/A d
2 A d/a D
1 a D/a D
3. The R and S loci are 35 m.u. apart. If a plant of genotype
is selfed, what progeny phenotypes will be seen and in what proportions?
4. The cross E/E · F/F × e/e · f/f is made, and the F1 is then backcrossed to the recessive parent. The progeny genotypes are inferred from the phenotypes. The progeny genotypes, written as the gametic contributions of the heterozygous parent, are in the following proportions:
Explain these results.
The two genes are 33.3 map units (m.u.) apart.
5. A strain of Neurospora with the genotype H · I is crossed with a strain with the genotype h · i. Half the progeny are H · I, and half are h · i. Explain how this is possible.
Because only parental types were recovered, the two genes must be quite close to each other, making recombination quite rare.
