liberstina [14]

Answer:

No, the butterflies may not have a natural predator in this environment; thus, they could displace native species that consume nectar

Explanation:

The escaped butterfly are considered an exotic species in their new environment. Exotic species in a new environment can establish themselves and sometimes outcompete or have selectional advantage over native species in that environment, eventually displacing the native species.

<em>Hence, that some of the butterflies were allowed to escape into the environment is not environmentally safe for the native species in that environment.</em>

All of the following are differences in transcription, RNA processing, and translation between prokaryotes and eukaryotes except
Mazyrski [523]

Answer:

the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in eukaryotes but not in prokaryotes.

Differences:

- the promoters in prokaryotes have a -35 and -10 box while in eukaryotes they are variable but have a TATA box from  

- the transcription initiation site there is a single RNA polymerase in prokaryotes while eukaryotes have multiple RNA polymerases

- the sigma factor associates with the promoter region in prokaryotes but in eukaryotes there are many basal transcription factors

Explanation:

Ribosomal and transfer RNAs are processed both in prokaryotic and eukaryotic organisms. However, mRNA is only processed in eukaryotes. In eukaryotic cells, mRNA processing involves:

1. Capping at the 5' end. This process has several functions including regulation of nuclear export, prevention of eukaryotic mRNA degradation and promotion of translation.

2. Splicing in order to remove introns and conserve coding exons. Splicing helps to increase the diversity of the eukaryotic mRNAs (and therefore eukaryotic proteins)

3. Polyadenylation by the addition of a poly(A) tail at the 3' end. The poly(A) tail makes the eukaryotic mRNA molecule more stable and also prevents its degradation by exonucleases.

​In human audition, the vibration of the ossicles is triggered by the vibration of the ____ and transmitted directly to the ____
goblinko [34]

In human audition, the vibration of the ossicles is triggered by the vibration of the tympanic membrane (the eardrum) and transmitted directly to the fluid and membranes of the inner ear.

The inner ear is shaped like a snail with a thousands of tiny hair cells in it and it is called the cochlea. Hair cells change the vibrations into electrical signals that are sent to the brain through the auditory nerve.

The changes to the cuttlefish’s skin are related to _______.
Pachacha [2.7K]
The bands of circular muscle structures that are located at the cuttlefish skin are most likely responsible for the changes of its outer covering. In addition, the colour cells that are present on the cuttlefish skin were estimated to be about 10 million which is why it was coined "the chameleons of the sea."
