asambeis [7]3 years ago
6 0

Explanation:

A. Shine-Dalgarno Sequence:

  • This is a binding site found in the messenger RNA (mRNA) in prokaryotic organisms. It is found upstream of the start codon AUG and aids in the initiation of  protein synthesis

B. SRP:

  • Signal Recognition Protein (SRP). This acts by binding to the bacterial ribosome, which as a result restricts protein synthesis.

C. NLS:

  • Nuclear Localisation Signal is a short amino acid sequence, which is responsible for transporting proteins from the cell cytoplasm into the nucleus. The NLS is also responsible for the development of the nuclear envelope of the cell.

D. Ubiquitin:

  • Found predominately in Eukaryota, the ubiquitin is a protein that aids in the control of other proteins within the organism.

E. Specificity Factor:

  • Also known as the sigma factor, is responsible for the initiation of bacterial transcription. It is recycled during the transcription process and is only required at the initiation of transcription.

F. CRP:

  • cAMP Receptor Protein (CRP) is involved in catabolite (glucose) repression and serves as an inducer in the process.

On your own: Click Return to original settings and Restart. Investigate the effects of agriculture on
Scrat [10]

Agriculture negatively affects reef ecosystems because the soil and the sea have a direct interaction of substances and minerals that can be altered with the intensification of agriculture.

<h3>What is agriculture?</h3>

Agriculture is a human activity that is based on planting seeds in the ground so that they develop and form plants that have uses such as food or others.

This is one of the oldest activities of humanity and has allowed communities to develop and create trading systems, wooden constructions, navigation, among others.

<h3>What impact does agriculture have on the reefs?</h3>

Agriculture generally takes place in coastal areas or near rivers because the composition of the soil must have certain minerals necessary for plants to grow.

Additionally, the components of the soil go underground to the sea and provide the water with different substances that contribute to marine life. However, the use of pesticides and other agricultural chemicals could reach the sea through runoff and affect the reefs.

What is one way scientists know that Maiacetus lived in the ocean?
IgorC [24]

Answer The species is known from three individuals, all of which were found in the Habib Rahi Rock Formation of Pakistan

Maiacetus is significant because of how well the skeletons were preserved. Over 90% of the bones from the male were found intact, which is almost unheard of for a specimen this old!

Their skeletons have all been found among fossils of sea-creatures which suggests they lived in the sea.

The fore-snout is starting to elongate. An elongated fore-snout is found in all modern whales and all transitional whales after Maiacetus.
