You perform an in situ hybridization on Drosophila melanogaster embryos. You apply a probe labeled with a fluorescent stain that

is complementary to mRNA transcripts of the gene hunchback. In early stages of embryogenesis you observe fluorescence for the entire anterior half of the embryo only. In embryos at a later stage of development you see the same pattern in the anterior, and also a stripe of fluorescence in the posterior half. What can you conclude about the expression of hunchback from this? Group of answer choices Hunchback moves from the anterior of the embryo to the posterior during development. Hunchback expression is more important in the anterior than in the posterior. Hunchback is never expressed in the posterior half of the embryo. Hunchback is first expressed in the anterior of the embryo and later in a portion of the posterior. Hunchback has been "knocked out" in some portions of the embryo.

Explain the connection between the beginning of life and the universal genetic code
GaryK [48]

The connection between the beginning of life and the universal genetic code is that they all started with a simple one celled molecule. The Universal genetic code is a common language for almost all organisms to translate nucleotide sequence of deoxyribonucleic acid that is DNA and ribonucleic acid that is RNA to amino acid sequences of proteins. All living Organisms have a genetic code generally represented by the sequence of nucleotides in their DNA.

Two planets with the same mass and atmospheric conditions orbit a single star. Planet A is closer to the star than Planet B. Whi
sveticcg [70]

Answer:

Planet B is expected to be cooler than Planet A.

Explanation:

In the given case, planet A is closer to the star than planet B. Their atmospheric conditions and mass is same so their surface temperature will depend on their distance from the star. Since planet A is closer, it will receive more radiation from the star. In turn it will be hotter to re-radiate that energy back to space. Hence, average surface temperature of planet B will be lower than planet A.

How have federal and state authorities attempted to eradicate Burmese Pythons from the Everglades?
Usimov [2.4K]

Federal and state authorities have attempted to eradicate Burmese pythons from the Everglades by allowing the hunting and trapping of these animals, giving rewards to these hunters.

<h3>How was the hunt to eradicate Burmese pythons from the Everglades?</h3>

In Florida, they tried everything to end the Burmese python plague that threatens to devour native species of the Everglades, one of the most valuable wetlands in the world. They trained dogs to sniff them out, they were attracted with pheromones, they implanted radio transmitters to locate their hiding places, they set traps. But after several years of experimentation, the best method they have found is the most rudimentary. “With two hands and balls of steel”

With this information, we can conclude that Federal and state authorities have attempted to eradicate Burmese pythons from the Everglades by allowing the hunting and trapping of these animals, giving rewards to these hunters.
