D.mutations
Im sure it cannot be anything else
The two enzymes that are used during DNA replication is helicase
and polymerase. Each enzyme has distinct role that made it a vital part of the replication.
In the course of DNA replication, the initial stage is to unzip the double
helix structure of the DNA molecule by the enzyme helicase, which breaks the
hydrogen bonds that holds the complementary bases of DNA.
Moreover, the DNA polymerase has the ability to exactly copy a
DNA template. This enzyme binds to the leading strand and then adding a new
complementary nucleotide bases to the DNA strand. In addition, it catalyzes the joining of
deoxyribonucleoside 5′-triphosphates (dNTPs) to form the increasing DNA chain.

Explanation:
Because we always seek to make sense of any perceived stimulus to better understand the reality that surrounds us and act before it. Through perception we process information from the senses, with which the brain builds and tries to give meaning to those stimuli that reach it. However, each person captures, selects and organizes sensory stimuli differently and, therefore, arrives at different interpretations and responses when solving a problem, in which memory and experience also form a fundamental role. Thus, differences between perceptions help explain how people interpret the environment and why they behave differently in the same situation. For example, when we recognize a specific object, an action can be initiated, in which a motor activity is propitiated in response to that recognition, and which can be different in each person.
Answer:
b. Mitochondrial respiration
Explanation:
Mitochondrial respiration of plants involves the participation of two major electron transport routes:
1. Cytochrome c oxidase route: cyanide sensitive and coupled to three energy conservation sites.
2. Cyanide-insensitive alternative route: involves alternative oxidase (AOX), branches off the cytochrome oxidase route into the ubiquinone pool, with no energy conservation thereafter as AOX is able to directly oxidize ubiquinol and reduce oxygen to water.
Regardless of the route followed, mitochondrial breathing is a long and complex process. However, it is through this breath that at a given moment electrons are passed to oxygen through a carrier channel in the inner mitochondrial membrane. This happens when cytochromes to and some molecules that have a heme group (with an iron atom) and are linked to a transmembrane protein that connects the matrix to the mitochondrial intermembrane space and have two copper atoms that allow the transport of electrons to the final acceptor, oxygen (O2).

The balanced equation is
4NO2(g)+O2(g)+2H2O(l) ==> 4HNO3(aq)
Determine the molar mass of NO2 and HNO3.
Atomic weight nitrogen = 14.0067
Atomic weight hydrogen = 1.00794
Atomic weight oxygen = 15.999
Molar mass NO2 = 14.0067 + 2 * 15.999 = 46.0047 g/mol
Molar mass HNO3 = 1.00794 + 14.0067 + 3 * 15.999 = 63.01164 g/mol
moles NO2 = 14000 g / 46.0047 = 304.3167329 mol
Looking at the balanced equation
4NO2(g)+O2(g)+2H2O(l) ==> 4HNO3(aq)
it's obvious that each mole of NO2 will produce one mole of HNO3. So we should have 304.3167329 moles worth. Just multiply by the molar mass.
304.3167329 mol * 63.01164 g/mol = 19175.49642 g = 19.17549642 kg
Since our data only has 2 significant figures, round to 2 figures, giving 19 kg.</span>
