Read the passage from Darwin's journal. sorry its so long
The Amblyrhynchus, a remarkable genus of , is confined to this archipelago; there are two species, resembling each other in general form, one being terrestrial and the other aquatic. This latter species (A. cristatus) was first characterized . . . from its short, broad head, and strong claws of equal length, that its habits of life would turn out very peculiar, and different from those of its nearest ally, the iguana. It is extremely common on all the islands throughout the group, and lives exclusively on the rocky sea-beaches, being never found . . . even ten yards in-shore. It is a hideous-looking creature of a dirty black colour, stupid, and sluggish in its movements. The usual length of a full-grown one is about a yard, but there are some even four feet long; a large one weighed twenty pounds: on the island of Albemarle, they seem to grow to a greater size than elsewhere. Their tails are flattened sideways, and all four feet partially webbed. They are occasionally seen some hundred yards from the shore, swimming about; and Captain Collnett, in his voyage says, “They go to sea in herds a-fishing, and sun themselves on the rocks; and may be called alligators in miniature.” It must not, however, be supposed that they live on fish. When in the water, this lizard swims with perfect ease and quickness, by a serpentine movement of its body and flattened tail—the legs being motionless and closely collapsed on its sides. A seaman on board sank one with a heavy weight attached to it, thinking thus to kill it directly, but when an hour afterwards, he drew up the line, it was quite active. Their limbs and strong claws are admirably adapted for crawling over the rugged and fissured masses of lava, which everywhere from the coast. In such situations, a group of six or seven of these hideous reptiles may oftentimes be seen on the black rocks, a few feet above the surf, basking in the sun with outstretched legs.
What structural adaptation does the A. cristatus lizard have to help them climb rocks?
Awnsers:
A.strong claws
B.black color
C.flattened tail
D.webbed feet
Answer:
A) strong claws
Explanation:
cause if they werent strong they would break if they tried to climb the rocks... also the first guy said webbed feet cause there is a VERY SIMILAR question that asked how they could swim... its in the screenshot of what he was answering
The structural adaptation does the cristatus lizard have to help them climb rocks is strong claws.
Explain your answer briefly?If they were not strong they would break if they tried to climb the rocks. Also the first guy said webbed feet cause there is a very similar question that asked how they could swim.
Thus, option "A" is correct, strong claws.

Which is NOT a role played by a type of RNA in protein synthesis?
O mRNA transcribes the DNA template.
rRNA makes up ribosomes, which translate the genetic code into a protein.
O tRNA pairs RNA bases with amino acids.
O pRNA is the product of chemically linked amino acids.
Answer:
pRNA is the product of chemically linked amino acids.
Explanation:
All the other choices are exactly the roles of RNA in protein synthesis: mRNA "messenger" RNA transcribes the DNA and travels out of the nucleus; then rRNA "ribosomal" RNA in the ribosome helps assemble the protein using the mRNA; tRNA "transfer" RNA brings amino acids to the assembly line of ribosome and mRNA.
There is no pRNA that I know of, although there are many types of other RNAs like piRNAs (piwi RNAs!) or siRNAs.

When are two populations likely to have very similar allele frequencies?
A. If the selective pressures are different
B. If there is a high mutation rate
C. If there is a large amount of genetic drift
D. If there is a large amount of gene flow
Answer:
c). If there was a large amount of genetic drift.
If the price of gene drift is excessive enough, then two populations will have equivalent allele frequencies and consequently can be taken into consideration as a single powerful population.
What causes allele frequencies to live equally?Allele frequencies continue to be constant over the years due to the following: there is no considerable price of a brand new mutation. individuals with all genotypes are similarly able to mate and pass on their genes; that is, there's no choice against any precise genotype.
What are two impacts of allele frequencies of a population?The natural choice, genetic drift, and gene go with the flow are the mechanisms that purpose modifications in allele frequencies through the years. while one or greater of those forces are appearing in a populace, the populace violates the Hardy-Weinberg assumptions, and evolution occurs.

Which evidence has led scientists to conclude that there are different layers within Earth's interior?
(1) analysis of earthquake wave data
(3) rock samples taken from Earth's core
(2) measurement of Earth's diameter
(4) temperatures taken within each layer
Answer:
Explanation:
1) análisis de datos de ondas sísmicas
Evidence has led scientists to conclude that there are different layers within Earth's interior based on analysis of earthquake wave data, measurements of Earth's diameter, and temperatures taken within each layer, so options 1, 2, and 4 are correct.
What is the significance of the different layers within Earth?There are various layers on the earth with distinct significance, such as the crust and the upper part of the mantle, which make up the lithosphere, which is the solid part of the Earth, and the tectonic plates that are constantly moving and colliding, which causes earthquakes and volcanic activity. The core is the inner part that has the magnetic fields, and the mantle is the part present in between the crust and the core.
Hence, evidence has led scientists to conclude that there are different layers within Earth's interior based on analysis of earthquake wave data, measurements of Earth's diameter, and temperatures taken within each layer, so options 1, 2, and 4 are correct.

Use what you know about natural selection to fill in the blanks in the hypothesis. It should answer the lab question, “What is the effect of the type of food available on the frequency of different types of bird beaks?”
Hypothesis: If the type of food available changes, then…
…because…
Answer: The independent variable of the lab is the type of food that is available to the birds. The food type changes in a given environment, then the amount of each type of bird beak will changes as birds with beaks more suited to the available food will consume more successfully over time.
Explanation:
With the changes in the available food, the frequency of the beak type will also change as birds with beaks better suited to the available food become more successful.
What are different types of bird beaks?There are many types of beaks in birds, some of these can be:
Crushing beak.Curved beak.Piercing and tearing beak.Birds of prey.Stickybeak.With the changes in the available food, the frequency of the beak type will also change as birds with beaks better suited to the available food become more successful.
