(Fill in the blank) When comparing DNA and structural characteristics between plant species, the similarities that appear can indicate a genetic adaptation to a particular environment, between them.

Explanation:

The evolution of the spice indicates that there were changes in the environment where these plants were able to adapt genetically, and not only that but they transmitted it in their generations, that is why many manifest the same genetic code, if this gene was inherited among them it means that the species EVOLVED.

Otherwise, those genes that generate benefits for the plants but are not transmitted in the parent plants will not be considered as an evolutionary change of the species but individual of the plant.

The genetic changes produced by modifications in the environment translate into phenotypic changes, thus generating a more suitable species with a greater chance of survival.

Answer:

Diffusion

Explanation:

Diffusion is the movement of molecules from a region of high concentration to a region of low concentration. Had the question been specific on water molecules, then the answer would have been osmosis.

The phosphodiester bonds in the backbone of DNA are covalent bonds that hold together the sugar-phosphate backbone of the DNA molecule. The hydrogen bonds between the nitrogenous bases of the DNA, on the other hand, hold the two complementary strands together and stabilize the DNA double helix.

This difference in bond types has significant implications for the overall functionality of the DNA molecule. For one, the phosphodiester bonds are relatively strong and stable, allowing the DNA to withstand various chemical and physical stresses. The hydrogen bonds, on the other hand, are weaker and more easily broken, which allows the two complementary strands of DNA to separate during replication and transcription. In addition, the hydrogen bonds are location-specific and only occur between specific pairs of nitrogenous bases, which gives DNA its characteristic double helix structure.

Overall, the difference in bond types between the phosphodiester bonds in the backbone and the hydrogen bonds on the steps of the DNA molecule is a critical factor in the stability, replication, and transcription of DNA.

Krypton 85 decays into rubidium 85 with a half-life of 10.76 years, which means that half of the initial krypton 85 atoms will decay into rubidium 85 in 10.76 years.

The radioactive decay of krypton 85 can be represented by the following equation:

Kr-85 → Rb-85 + β-

where β- represents an electron emitted in the decay process. Krypton 85 decays into rubidium 85 by emitting a beta particle.

The half-life of krypton 85 is 10.76 years, which means that half of the initial krypton 85 atoms will decay into rubidium 85 in 10.76 years.

\(N = \frac{N_{0}}{2^{t/T} }\)

where N is the current number of krypton 85 atoms, N0 is the initial number of krypton 85 atoms, t is the time elapsed, and T is the half-life of krypton 85.

In this case, we know that the initial number of krypton 85 atoms is 4, and the current number of krypton 85 atoms is 4/2 = 2. We also know that the sample contains 12 rubidium 85 atoms.

Therefore, we can use the above equation to find the time elapsed:

\(2 = \frac{4}{2^{t/10.76} }\)

\(2^{t/10.76} = 2\)

\(\frac{t}{10.76}\) = log2(2)

t = 10.76 years

The following doesn’t augment the concentration of oxygen in the atmosphere Ozone Decomposition (Option B).

Ozone decomposition does not increase the concentration of oxygen in the atmosphere because it breaks down ozone into oxygen. The oxygen already exists in the atmosphere and no new oxygen is produced as a result.

Photosynthesis, water decomposition, and phytoplankton photosynthesis, on the other hand, are all responsible for increasing the oxygen concentration in the atmosphere. Photosynthesis is the process by which plants produce oxygen. Water decomposition is the process of breaking down water into hydrogen and oxygen gas. Phytoplankton photosynthesis is the process by which phytoplankton produce oxygen through photosynthesis.

Hence, the correct option is B) Ozone Decomposition.

The correct is option C) Water Decomposition. The concentration of oxygen in the atmosphere is not augmented by water decomposition. The water molecule (H2O) is a compound that contains oxygen, but when it undergoes decomposition, it does not release oxygen as a product.

In fact, during water decomposition, the oxygen that is present in the molecule combines with hydrogen atoms to form water molecules, thereby decreasing the amount of free oxygen in the atmosphere.Photosynthesis, on the other hand, is a process by which plants use sunlight to convert carbon dioxide and water into organic matter and oxygen. This process is responsible for producing most of the oxygen in the atmosphere, making it the primary source of oxygen.Ozone decomposition also contributes to the concentration of oxygen in the atmosphere. Ozone (O3) is a molecule that contains three oxygen atoms and is an important component of the ozone layer, which protects the Earth from harmful UV rays. When ozone decomposes, it releases free oxygen into the atmosphere.

Phytoplankton photosynthesis is another process that contributes to the concentration of oxygen in the atmosphere. Phytoplankton are microscopic algae that live in aquatic environments, and they are responsible for producing a significant amount of the oxygen in the atmosphere.

The total length of DNA in the body is approximately 100 trillion meters, which is equivalent to 100 billion kilometers or about 6.6 billion times the distance from the Earth to the Sun.

Assuming that each cell contains about 2 meters of DNA and there are 50 trillion cells in the human body,

the total length of DNA in the body can be calculated by multiplying the length of DNA per cell by the number of cells in the body:

Total length of DNA = 2 meters/cell x 50 trillion cells

Total length of DNA = 100 trillion meters

Therefore, the total length of DNA in the body is approximately 100 trillion meters,

which is equivalent to 100 billion kilometers or about 6.6 billion times the distance from the Earth to the Sun.

Explanation:

As with many chemical reactions, the rate of an enzyme-catalysed reaction increases as the temperature increases.

An action potential can start in the middle of an axon and proceed in both opposite directions when: the axon has myelination and is at least partially depolarized.

In myelinated axons, the action potential can initiate at any point along the axon, not just at the axon hillock or the initial segment. This is known as "saltatory conduction." When an action potential is generated at a specific point, it depolarizes the adjacent region of the axon, triggering the opening of voltage-gated ion channels. However, the myelin sheath prevents the ion flow and action potential propagation in that specific area. If the axon is partially depolarized and the membrane potential reaches the threshold, the depolarization can overcome the inhibitory influence of the myelin sheath. This allows the action potential to be initiated in the middle of the axon. Once initiated, the action potential can propagate in both directions, towards the axon terminals and back toward the initial segment. This type of bidirectional conduction is possible due to the presence of voltage-gated ion channels along the axon. However, it's important to note that bidirectional propagation is more efficient and common in unmyelinated axons where there are more ion channels available for depolarization in both directions.
