Which of the following is an example of post-transcriptional control of gene expression?a. gene amplification contributing to ca
MAVERICK [17]

The correct answer is: b. the removal of introns and alternative splicing of exons

Post-transcriptional regulation includes processes of regulation between transcription and translation such as RNA splicing, capping, addition of poly-A tail,  RNA editing.

RNA splicing represents the process of RNA processing in which newly synthesized pre-mRNA transcript is converted into a mature mRNA. This process occurs only in eukaryotic organism and includes the removal of introns and joining together the exons. RNA splicing might occur during or immediately after transcription and it is performed by spliceosome (complex of small nuclear ribonucleo proteins).

Alternative splicing is a regulated process in which a single gene can code for multiple proteins because particular exons of a gene may be included within or excluded from the final mRNA.

In a hydra, digestion is completed _________.
OLEGan [10]

In a hydra, digestion is completed intracellularly.

Hence option (a) is correct.

Small, freshwater organisms of the phylum Cnidaria and class Hydrozoa are grouped under the genus Hydra. They are indigenous to temperate and tropical climates. 

The digestion takes place intracellularly in Hydra.

Because of their ability to regenerate and the fact that they don't appear to age or experience old age, hydra have drawn the attention of biologists.

Like most other cnidarians, hydras have a pretty straightforward digestive system.

They have a two-way digestive system, which differs from mammals in that food and waste enter and exit through the same aperture. A "blind gut" is the name for this configuration.

The center of the hydra's body is occupied by its digestive tract.

A species of mud snail was studied for five years. During this time, scientists observed the season in which they mated, the num
sergij07 [2.7K]

The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.
