Answer:

The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.

A friend asks you how to determine the strongest intermolecular force present in a pure sample. Write down for them the steps yo
LenaWriter [7]

The best method used to determine the strongest intermolecular forces is to check it's it boiling or melting point.

Explanation:

So, when the molecules are polarized, the charges on the atom becomes greater which would lead to a greater intermolecular force. hence, those components will have a high boiling point. Here is the ascending of atomic bonds which would help us to determine what bonding so we could say whether it is the strongest or not.

Ionic bonds>Hydrogen bonding>Van der Waals dipole interaction>Van der Waals dispersion forces

So, you have to heat or melt the pure sample to determine the strongest intermolecular force depends on the components in the sample.

What's the new peptide chain when the new DNA segment is translated?
saveliy_v [14]

Answer:

The correct answer is - Methionine, serine, histidine, aspartate, glycine

Explanation:

The new segment of DNA is: 3'-TACAGGGTGCTACCCACT-5', which performs two processes to form a peptide chain, transcription, and translation. In transcription, the DNA segment is encoded to an mRNA molecule which has its complementary sequence to DNA sequence.

New DNA strand: 3'-TACAGGGTGCTACCCACT-5'

mRNA sequence: 3'-AUGUCCCACGAUGGGUGA-5'

The translation of this mRNA would be on the basis of chart

AUG - Methionine (start codon)

UCC - serine

CAC - histidine

GAU - aspartate

GGG - glycine

UGA -  stop codon

The peptide chain would be - Methionine, serine, histidine, aspartate, glycine

Which is a leading theory for the formation of fossil fuels?​
Ber [7]

Answer:

Currently the biogenic theory is the leading explanation for the formation of fossil fuels and it’s believed that the petroleum we most commonly use took anywhere from 1 million to 1 billion years to form and represents a wide spectrum of useful petroleum and natural gas products including methane, propane, butane, hexane, octane and others
