I believe the correct answer is true. Veins are often formed from hot water solutions. Hydrothermal deposits are a very common method of filling already existing fractures and occurs at varying depths. T<span>here are lots of veins formed by hot water that cause fractures or work their way up into non fractured rock. </span>

Which type of species is the first to occupy a bare site?

Evgen [1.6K]

Answer:

pioneer species

Explanation:

Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support plants.

Answer:

c. The starch stayed in the bag and the iodine leaked into the bag and the reacted with it, turning the solution black.

Explanation:

According to the given information, the solution inside the dialysis tubing has starch while water present outside has iodine. The color of the water present outside the dialysis tubing does not change which means that starch did not leak out of the bag and stayed in the bag itself. On the other hand, the starch solution present inside the bag turned black representing the fact that iodine entered the bag. The reaction of starch with iodine produces a blue-black color.

DNA is transcribed to messenger RNA (mRNA), and the mRNA is translated to proteins on the ribosomes. A sequence of three nucleot

Maru [420]

Answer:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA

Explanation:

From the amino acid chart, the start codon is represented by the codon AUG which also code for the amino acid methionine. There are three stop codons including UAA, UAG, and UGA. The stop codons signal the end of the translation process of the mRNA. Every other codon within the mRNA chain codes for different amino acids except methionine.

Hence, using the attached amino acid chart:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA
