The Epithalamus partially forms the posterior roof of the diencephalon and covers the third ventricle.

The Epithalamus function is to link the limbic system to other areas of the brain.

The pineal gland is located in the epithalamus, a small region of the diencephalon.
The functions of Epithalamus includes secretion of Melatonin by pineal gland which is a part of Epithalamus.
Melatonin is also known as enzyme of darkness.
It regulates sleep, circadian rhythms, metabolism and also increases immunity.

Thus, from the above points we can conclude that the Epithalamus forms a portion of the diencephalon's posterior roof and covers the third ventricle.

Your friend brings you rocks with a thick layer of oxidation weathering, and no other visible signs of weathering. this is a clu

Vsevolod [243]

<span>A moist environment because physical weathering processes such as oxidation take place most quickly in the presence of water. There are three types of weathering, physical, chemical, and biological. For the physical weathering, there are two main types. Freeze-thaw cycles and exfoliation. Obviously the freeze-thaw cycles require water and the exfoliation generally happens through thermal expansion and contraction which doesn't require water. But since neither of these mechanisms were observed, that doesn't indicate if the area was wet or dry. Biological weathering is caused by plants or animals breaking down rocks via chemical (acid) or mechanical (root growth) means. Life generally indicates the presence of water, but since this form of weathering wasn't observed, we still don't have enough data. Chemical weathering is caused by rain water reacting with the rocks to form new minerals and salts. There are several types such as acidic rainwater dissolving part of the rock, and oxidation. With this in mind, let's take a look at the available options. A moist environment because there is a greater density of oxygen in the atmosphere in the presence of water. * Yes, we need a moist environment, but the density of oxygen is fairly constant world wide regardless of how moist or dry the environment is. So this is a bad choice. A moist environment because physical weathering processes such as oxidation take place most quickly in the presence of water. * Water speeds up chemical weathering of all types. So this is the correct choice. A dry environment because the increased albedo of deserts encourages physical weathering processes such as oxidation. * Yes, the increased albedo of deserts does speed up spalling, but oxidation is a CHEMICAL weathering process, not a PHYSICAL one. So this is a bad choice. A dry environment because in the absence of water oxidation is the dominant weathering process. * Water speeds up oxidation quite a bit. And since the observed oxidation is thick, there's been quite a bit of weathering. So this is a bad choice.</span>

Answer:

I think stream bank. It grows in moist places and wetlands, and is especially abundant along streamsides and riparian areas at elevations below 1400 m.

What would be the most likely effect on the transcription of the trp structural genes for the mutation scenarios provided? mutat

blagie [28]

Answer:

I've responded to each scenario individually, please see below:

1. mutation that prevents ribosome binding to the mRNA

No transcription occurs

2. 5' UTR mutation that changes region 1 tryptophan codons into alanine codons

Transcription when alanine is low

3. mutation that creates a stop codon in region 1 of mRNA 5' UTR

Transcription occurs, a truncated protein will be made during translation

4. deletions in region 2 of the mRNA 5' UTR

Transcription occurs, region 1 and 2 might get paired together

5. deletions in region 3 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

6. deletions in region 4 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

7. deletion of the string of adenine after region 4 of the mRNA 5' UTR

Transcription occurs, however, it will not be as stable a molecule because of losing its polyA tail

Hope that answers the question, have a great day!
