Upturned Face by Stephen Crane (excerpt)

Read the excerpt about two men trying to bury a dead soldier right in the middle of a battle.

"Yes," said Lean. The two privates stood waiting, bent over their implements. "I suppose," said Lean, "it would be better if we laid him in ourselves."

"Yes," said the adjutant. Then apparently remembering that he had made Lean search the body, he stooped with great fortitude and took hold of the dead officer's clothing. Lean joined him. Both were particular that their fingers should not feel the corpse. They tugged away; the corpse lifted, heaved, toppled, flopped into the grave, and the two officers, straightening, looked again at each other—they were always looking at each other. They sighed with relief.

The adjutant said, "I suppose we should—we should say something. Do you know the service, Tim?"

"They don't read the service until the grave is filled in," said Lean, pressing his lips to an academic expression.

"Don't they?" said the adjutant, shocked that he had made the mistake.

"Oh, well," he cried, suddenly, "let us—let us say something—while he can hear us."

"All right," said Lean. "Do you know the service?"

"I can't remember a line of it," said the adjutant.

Lean was extremely dubious. "I can repeat two lines, but—"

"Well, do it," said the adjutant. "Go as far as you can. That's better than nothing. And the beasts have got our range exactly."

Lean looked at his two men. "Attention," he barked. The privates came to attention with a click, looking much aggrieved. The adjutant lowered his helmet to his knee. Lean, bareheaded, he stood over the grave. The Rostina sharpshooters fired briskly.

What is some conlusive evidence that organisms of two different species share a common ancestor?

Answers

Well, according to the theory of evolution, the reason that organisms of two different species would share a common ancestor is that way back before evolution really took place, there were species that were all grouped together. After time, these species needed to evolve in order to adapt to the way the environments were changing. For example, dogs and wolves are not the same species, but are related and share a common ancestor, causing them to look alike.

Describe how Mendel showed that the green-seed trait did not disappear but was only masked.

Answers

Mendel had determined that the allele for green seeds had not vanished because after the second generation of yellow seeds, green seeds started appearing again. He logically concluded that the yellow allele was a dominant trait and the green allele was a nondominant trait.

In snapdragons, there is one allele that produces red flowers and another allele that produces white flowers. Neither allele is dominant and heterozygous individuals have pink flowers. A plant breeder decides to cross a red flowered snapdragon with a pink flowered snapdragon. What percentage of the offspring do you expect will have red flowers?

Answers

You do:
R R
R
r
Your offspring would be: RR, RR, Rr, Rr
So, about 50% of the offspring will have red flowers
Your answer is
50%

Final answer:

When you cross a red snapdragon (RR) and a pink snapdragon (Rr), you will expect 50% of the offspring to have red flowers

Explanation:

In snapdragons, red and white flower color exhibits incomplete dominance, where the red (R) and white (r) alleles neither of them is completely dominant or recessive. This results in the heterozygous condition (Rr) appearing as pink flowers. In this case, the red flowered snapdragon would have a RR genotype, while the pink one would have a Rr genotype.

If you cross the red (RR) and the pink (Rr) snapdragons, the possible genotypes of the offspring would be RR and Rr, corresponding to red and pink flowers. Half of the offspring are expected to be RR (red), and the other half Rr (pink). Therefore, 50% of the offspring are expected to have red flowers.
