a cricket has a diploid genome of 1.2 billion base pairs. assume that there are about 200,000 individuals in the population and that the mutation rate is one per 100 million base pairs. on average, how many new mutations will occur in an individual cricket?

Theories that were obtained while doing research using radioactive isotopes disagree as to whether the [tex]O_{2}[/tex] produced during photosynthesis came from [tex]CO_{2}[/tex] (carbon dioxide) or [tex]H_{2}O[/tex] (water).

Most scientists believed that plants produced [tex]O_{2}[/tex] by removing it from [tex]CO_{2}[/tex] in the 1800s. In the 1950s, researchers tested this theory by tracking the fate of oxygen atoms during photosynthesis using the heavy oxygen isotope [tex]^{18}O[/tex].

There was two experiments:

1. A plant exposed to [tex]^{18}O[/tex]-containing carbon dioxide produced no labeled oxygen gas ([tex]^{18}O[/tex] containing).

2. A plant given [tex]^{18}O[/tex] water produced tagged [tex]O_{2}[/tex].

These investigations demonstrated that the [tex]O_{2}[/tex] produced during photosynthesis is derived from [tex]H_{2}O[/tex] rather than [tex]CO_{2}[/tex].

The biological process responsible for the precise changes in CO2 that have been seen is photosynthesis (for both light and dark conditions). Carbon dioxide and water are the reactants of photosynthesis, and light energy transforms them into glucose and oxygen (the products).

Plants ingest water (H2O) and carbon dioxide (CO2) during photosynthesis from the soil and atmosphere. In contrast to carbon dioxide, which is reduced within the plant cell and gains electrons, water is oxidized within the partition of the plant. Due to this, carbon dioxide and water are converted into glucose and oxygen, respectively. Once the oxygen has been returned to the atmosphere, the plant stores energy within glucose molecules.

Accordingly, we can conclude that the biological process is responsible for the specific changes in CO2 that have been observed in photosynthesis. The reactants, carbon dioxide and water, are changed into glucose and oxygen by light energy during photosynthesis.

Repeated irrigation in dry climates leads to accumulation of salts in the upper layers of the soil, a process called salinization.

Soil salinity is the amount of salt in the soil.  The process of increasing the salt content is called salinization.  Salt is a naturally occurring compound found in soil and water.  Salinization can be caused by natural processes such as mineral leaching or the withdrawal of salt deposits from the oceans.  Salinization can also occur due to human activities such as irrigation.

Causes of soil salinity

The accumulation of too much salt, especially on the surface, is caused by the movement of salt through the capillary process from the part in the soil which is filled with liquid with dissolved salts, to the surface.  The evaporation process draws liquid from the soil to the surface, and the evaporated liquid leaves salt on the soil surface.  Concentrated salt can also come from chemical fertilizers.

Salinization is a process caused by:

- high salt content in water

- landscape features that cause salt to move through the movement of groundwater

- climatic factors that cause salt accumulation

- human activities such as logging, irrigation, aquaculture, and salting to melt snow and ice.

- The high salt content causes soil degradation and vegetation is unable to grow on it.

The change in temperature will be highest for lead metal. So option (D) is the correct answer.

To calculate the heat absorbed or released

q=mC×ΔT

where,

q = heat absorbed = 200.0 J

m = mass of the substance

C = specific heat of substance

ΔT = change in temperature

Amount of heat is absorbed and the mass is all the same. Therefore, the temperature change depends only on the specific heat.

ΔT = q/ mC

From the above we can see that the temperature change is inversely proportional to the specific heat. The higher the specific heat, the smaller the temperature change.
