Boiling an egg and vegetables rotting.

The right answers are: boiling an egg and vegetables rotting.

* When a compound is heated, a change of state occurs, usually from the solid to the liquid, or from the liquid to the gas.

The coagulation of the egg seems to be a paradoxical situation with regard to the phenomena of fusion and evaporation.

With the increase of the temperature, there is denaturation of the proteins, that is to say that the hydrogen bonds are broken. There is then a rearrangement of the tertiary structure of the proteins.


* In biology, decomposition (or rotting) is a process occurring in plant bodies from the moment they are deprived of life, degenerate under the action of biological factors completely changing their appearance and composition. The decomposition process involves a succession of microorganisms such as fungi and bacteria, most often anaerobic. In other words, it is the degradation of organic molecules by the action of microorganisms.

In plant pathology, decay follows a cryptogamic or bacterial plant disease. For example an attack of the microscopic fungus Botrytis cinerea on a wide range of crops: fruits, vegetables, ornamental plants and grapes.

What is the Molecular mechanism of DNA replication?
kolezko [41]

Answer:

DNA replication a process of copying of a cell's DNA.  DNA replication is semiconservative process which means that each strand in the double helix helps in the synthesis of new, complementary strand and conserve the parent template.

The Molecular mechanism of DNA replication is as following:

  1. The double starnded DN in binded with hydrogen bond, the enzyme helicase opens up the DNA at the replication fork.
  2. A single stranded binding protein prevent the rewinding of DNA and so binds to the DNA around the replication fork
  3. Topoisomerase prevent supercoiling at replication fork.
  4. The ezymes primase come in action and produces RNA primers which are complementary to the DNA strand.
  5. DNA polymerase III help to extends the primers and allow them to add  to the 3' end, to make new DNA.
  6. DNA Polymerase then remove RNA primers and replace with DNA.
  7. DNA ligase blocks the the gaps between DNA fragments.

So, this is the molecuar mechanism of DNA replication.

Given the parents AABBCc × AabbCc, assume simple dominance for each trait and independent assortment. What proportion of the pro
galina1969 [7]
The answer is C) 3/4

Let's analyze separately each of the traits:

Parental generation: AA x Aa
F1 generation:       AA AA Aa Aa
So, all progeny will <span>phenotypically resemble the first parent.

</span>Parental generation: BB x bb
F1 generation:       Bb Bb Bb Bb
So, all progeny will <span>phenotypically resemble the first parent.
</span>
Parental generation: Cc x Cc
<span>F1 generation:       CC Cc Cc cc
</span>Only 3 (CC, Cc, Cc) out of 4 progeny will <span>phenotypically resemble the first parent.

The genotypes for first two traits will not affect </span>phenotypical resemblance to the first parent. So, it only counts the third trait, for which the chance to have progeny that <span>phenotypically resemble the first parent is 3/4.</span>
