Geologists are conducting a study on many layers of different types of rock in the Grand Canyon. These geologists will likely find ancient fossils that reveal the history of life near the Grand Canyon in

igneous rock layers
layers of sedimentary rock
layers of volcanic rock.
metamorphic rock layers

Answer:

layers of sedimentary rock

Explanation:

Most rocks in the Grand Canyon are sedimentary rocks, formed while <em>sediments of sand and mud got deposited in thick layers and got compacted through the pass of time until becoming a rock</em>. Sedimentary rocks have been chronologically accumulating for years, reflecting the geological formation known as superposition. According to this sedimentary deposition, we can distinguish the older rocks located in the deepest areas from the younger rocks in more superficial layers.

As the sedimentary layers were deposited chronologically, they reflect the canyon history by keeping in each layer some of the forms of life that used to inhabit this area in the past. Such is the example of the superficial limestone stratum where many marine animal fossils are found, like clams, fish, and corals.

Drag the genotypes and phenotypes from the left to correctly complete the punnett square for the f2 generation. drag only blue l

Alex73 [517]

I found the exercise on the internet. Attached is the Punnett square and the labels to place in it.

For the spot (a), place the blue label "GG" because that square is correspondent to the combination of the alleles G and G from both parents. For the spot (b), place the pink label with a green pod because green is the dominant trait as both parents are heterozygous and present green colour.

For the spot (c), place the blue label "Gg" because that square is correspondent to the combination of the allele G from an egg and the allele g from the sperm. For the spot (d), place the pink label with a green pod because green is the dominant trait as both parents are heterozygous (as well as this genotype) and present green colour.

For the spot (e), place the blue label "Gg" because that square is correspondent to the combination of the allele g from an egg and the allele G from the sperm. For the spot (f), place the pink label with a green pod because green is the dominant trait as both parents are heterozygous (as well as this genotype) and present green colour.

For the spot (g), place the blue label "gg" because that square is correspondent to the combination of the alleles g and g from both parents. For the spot (h), place the pink label with a yellow pod because yellow is the recessive trait as both parents are heterozygous and present green colour.

One major difference between prokaryotic and eukaryotic cells is that prokaryotic cells

kicyunya [14]

Answer:

Eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not.

Explanation:

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
