Large central vacuoles, chloroplasts, and cell walls are only found in plant cells.
Large central vacuoles store nutrients and waste products, but they also maintain the plants' structures.
Cell walls also maintain structure and rigidity.
Chloroplasts are used in the process of photosynthesis, which only occurs in plants.
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.
Ans.
In human body, three types of blood cells are present, which include red blood cells, platelets, and white blood cells. Although these cells are started out alike, they show different shapes, sizes, and functions due to instructions that differentiate them into different types. These instructions are given by particular chromosomes present in the cells as the chromosomes consist of DNA that provides information to the cells, which is responsible for characteristic behavior of that cell.
Hence, the correct answer for the blank is 'B) chromosomes.'
Answer: Plants are cloned to produce identical plants quickly and economically.
