Answer:
The correct answer is "proteins are extracted from an environment, fragmented, and adaptors are added".
Explanation:
The missing options of this question are:
A) Software aligns sequences and assemble large portions of genome.
B) The samples are subject to polymerase chain reaction for amplification.
C) The sequences of the amplified fragments are determined by next-generation methods.
D) Proteins are extracted from an environment, fragmented, and adaptors are added
The correct answer is option D) Proteins are extracted from an environment, fragmented, and adaptors are added.
Metagenomic sequencing refers to the amplification and determination of all nucleotide sequences in a sample, which might contain multiple microorganisms and viruses in order to understand the presence and proportions of microbiota. Metagenomic sequencing involves the use of next-generation methods, to amplify and characterize all the nucleotides sequences. It is false to affirm that the proteins are extracted directly from the environment in this technique, since metagenomic sequencing is focused on the nucleotide sequences.
Answer:
Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm
<em>Note: The question is incomplete. The attachment below gives the complete question</em>
Explanation:
The outermost surface of a cell is bounded by the plasma membrane which functions to maintain the integrity of the cell as well as control the movement of particles in and out of the cell.
The ratio of the surface area of a cell to the volume of the cell indicates how big the cell is. When the surface area to volume ratio is small, the cell is very big, but if the surface area to volume ratio is big, the cell is small.
From the attachment below, the surface area (plasma membrane) per volume of plasma of the rectangular solids are as follows:
Solid 1: 10/2 = 5 cm⁻¹
Solid 2: 12.18/2 = 6.09 cm⁻¹
Solid 3: 19.0/2 = 9.5 cm⁻¹
Solid 4: 34.24/2 = 17.12 cm⁻¹
Solid 5: 65.79/2 = 32.895 cm⁻¹
Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm
