What are some ways in which the structure of a compound influences its function?

1 answer:

6 0

structure of a compound influences its function in many ways like we take example of phospholipid bilayer 1. The fact that the tails are hydrophobic means that they do not interact with water. When a bunch of phospholipids are floating around in water, they try to arrange themselves in a bilayer that shields the hydrophobic parts from water-based, or aqueous, surroundings.

2. The heads are hydrophilic and can then interact with water and other polar or charged substances on either side of the bilayer. The bilayer acts as a barrier that allows cells to maintain internal conditions that are different from external conditions, which is monumentally important for cells to operate properly.

3. Phospholipids demonstrate the intersection of structure and function in another way, too. We already know that fatty acids can be saturated or unsaturated and that unsaturated fatty acids have bends in their chains. Those bends prevent fatty acids from packing close.

Types of minerals change in heated (First blank) area rock. A record of biological time can be found in (second blank) area rock

Elina [12.6K]

Answer:

Types of minerals change in heated metamorphic area rock. A record of biological time can be found in sedimentary area rock. Matter changes state from liquid to solid to form igneous area rock

Explanation:

Metamorphic rocks can be described as a type of rocks which arise by the phenomenon of metamorphism. Immense heat and pressure changes previous rocks (sedimentary, igneous or other metamorphic rocks) into metamorphic rocks.

Sedimentary rocks can be described as the type of rocks which are made by the deposition of minerals or organic particles and hence, help in evolutionary studies.

Igneous rocks can be described as the rocks which are made from lava or magma (hence changing state from liquid to solid).

In amino acid monomers, the side group (R) is covalently bound to:

marissa [1.9K]

Answer:

a. The alpha-carbon

Explanation:

An amino acid is an organic molecule that contains a carboxyl (COOH) and a amino (NH2) group. It has a central carbon called as alpha carbon.

The carboxyl and amino groups are attached to the the alpha carbon. Apart from them, a side chain denoted by "R" is also covalently attached to it. Side chain varies in each amino acid and it imparts the unique properties to the particular amino acid.

If you wanted to sequence the genome of Ötzi, the 5,300-year-old "Iceman" mummy found in the Alps in 1991, which method would yo

Delvig [45]

The question is incomplete as it does not have the options which are:

a) DNA

b) AGCT

c) PCR

d) SNP

Answer:

PCR (polymerase chain reaction)

Explanation:

The polymerase chain reaction is the technique which replicates and produces multiple copies of the DNA molecule artificially in a short period of time.

The PCR technique employs a variety of enzymes and all the prerequisites which are required in the DNA replication in vivo conditions.

In the given question, if the genome of the mummy has to sequence then after the collection of samples from the bones, the DNA has to replicate through the process of PCR. The samples from the different bone structures can be compared and analysed and a complete genome sequence can be analysed.

Thus, PCR is correct.
