Answer:

The organic chemicals that helps cell membranes to conserve the internal fluids are phospholipids.

Explanation:

Phospholipids are used to form plasma membrane of the cell. Plasma membrane surrounds the cell contents like various cell organelles, nucleus, ribosomes and proteins. A phospholipid molecules is made up if a polar head containing a phosphate group and the two non-polar tails made of long chains of hydrocarbon of fatty acids.

The another name for plasma membrane is phospholipid bilayer. The polar head is hydrophilic that interactes with polar environment while facing outside the bilayer while the non-polar tail is hydrophobic in nature which makes the internal hydrophobic region of cell membrane which faces inside the bilayer.

Lesions to the medial geniculate of the amygdala block conventional auditory fear conditioning.

Medial geniculate

The medial geniculate body (MGB) is a collection of nuclei that receives heavy input from the IC and acts as a key synaptic junction on the routes that carry data to the cerebral cortex's auditory regions.

One should also think about how the medial geniculate's structure might affect its possible roles as a relay nucleus given the substantial studies on its anatomy. It is not in question that the MGv, which is the lemniscal portion of the MGB, "relays" accurate auditory information to the primary auditory cortex.

vagabundo [1.1K]

ATP is not generated directly in the citric acid cycle. Instead, an intermediate is first generated by substrate-level phosphorylation. The intermediate is GTP.

A purine nucleoside triphosphate is guanosine-5'-triphosphate.
It serves as one of the components necessary for the creation of RNA during transcription.
The main distinction between its structure and that of the guanosine nucleoside is the presence of phosphates on the ribose sugar of nucleotides like GTP.
Also known as guanosine triphosphate, this energy-dense nucleotide is similar to ATP and is made up of guanine, ribose, and three phosphate groups.
It is required for the creation of peptide bonds during protein synthesis.
Adenine nitrogenous base, sugar ribose, and triphosphate make up ATP, a nucleoside triphosphate, whereas guanine nitrogenous base, sugar ribose, and triphosphate make up GTP.
This is the main distinction between the two compounds.
The alpha-guanosine subunit's diphosphate (GDP) is converted into guanosine triphosphate (GTP), and the GTP-bound alpha-subunit subsequently separates from the beta- and gamma-subunits.

What did the structure of DNA’s double helix suggest about DNA’s properties? Select all that apply.

givi [52]

Completed part of the questionErrors in copying can result in changes in the DNA sequence that could be inherited by future generation.

Answer:

DNA stores genetic information in the sequence of its bases

DNA can be replicated by making complementary copies of each strand

Errors in copying can result in changes in the DNA sequence that could be inherited by future generation.

Explanation:

the fact that DNA is located in the Nucleus is not related to double strands.

the DNA csn change is not relevant ,

 therefore the above 3 options are the correct answers.
