Explanation:

The missing options for this question are:

A) paired fins

B) jaws

C) a well-developed notochord

D) a rasping tongue

The correct answer is option C) "a well-developed notochord".

Lampreys and hagfishes are two species of jawless fish that are uncommon to see, but they have more than 30 different species for each one of them. Both lampreys and hagfishes have a well-developed notochord, during their larvae and adult forms. The notochord provides support to their body as it has the function of a cartilaginous skeleton.

Which type of nutrition takes place in fungi ​
jarptica [38.1K]

Fungi get their nutrition by absorbing organic compounds from the environment. Fungi are heterotrophic: they rely solely on carbon obtained from other organisms for their metabolism and nutrition. Fungi have evolved in a way that allows many of them to use a large variety of organic substrates for growth, including simple compounds such as nitrate, ammonia, acetate, or ethanol. Their mode of nutrition defines the role of fungi in their environment.

a scientist isolates all of the mrnas in a kidney cell and reverse transcribes them into dsdna. the dsdna copies are then insert
SVETLANKA909090 [29]

When the dsDNA copies are then inserted into vectors and cloned into E. coli. the scientist has produced a cDNA library.

A collection of DNA fragments that have been cloned into vectors to identify and isolate desired DNA fragments is known as the DNA library. cDNA libraries and genomic libraries are the two types of libraries.

cDNA (Complementary DNA )library: cDNA is a DNA copy of an mRNA molecule that is produced by reverse transcriptase, a DNA polymerase that can use RNA or DNA as its template.

  • These are made by using mRNA as their starting material as templates.
  • They only represent genes in the genome that are expressed under particular conditions.
  • Because cDNA lacks introns, prokaryotic cells can express it.
