The individual bacteria that cannot synthesize histidine in the culture are likely to be genotypically and phenotypically different from the rest of the culture.

Mutation refers to sudden changes to the DNA sequence of organisms. Mutation can be silent without producing any physical effect.

A mutation can also be harmful to organisms. Once a modification is made to the DNA of some individual organisms out of the entire population of the same organism, such individuals are said to be mutants.

If the mutation has physical manifestations, the mutants will be both genotypically and phenotypically unique from the rest of the population.

If the mutation is silent, the mutants will be genotypically unique from the rest of the population, not phenotypically.

In this case, some individual bacteria in the entire culture are not able to synthesize histidine. Thus, these individuals will be different from the rest of the population both in genotype and phenotype.

They created stromatolites, which added oxygen to the atmosphere.

Prokaryotes that can reproduce independently produce organic compounds from carbon dioxide. Heterotrophic prokaryotes, in contrast, get their carbon from organic substances. The terminologies that describe how prokaryotes receive carbon and energy can be combined to further complicate the picture.

Phototrophs, which are autotrophic organisms that transform solar energy into chemical energy, first appeared within a billion years after the birth of the Earth.

Since plants can produce their own sustenance, they are referred to as autotrophs. Through the process of photosynthesis, plants create glucose using water, carbon dioxide, and solar energy. Some protist species also use photosynthesis to produce energy.

Genetic diversity is the analysis of variations in a single species and Species diversity is all the differences between different populations of species which means it is valid for more than one species.

The entire number of genetic features that make up a species' genetic makeup is referred to as genetic diversity. It can be related to a species' longevity and varies widely based on the number of species present as well as across species.

Species diversity is the range of species found in a certain community. In order to achieve the same mean proportional species abundance as that seen in the relevant dataset, a certain number of equally abundant species must exist.

Genetic diversity and species diversity are fundamentally different from one another because genetic diversity refers to DNA variations among members of the same species, whereas species diversity refers to the number of species in a region. Ecological diversity is the range of ecosystems present in a region.

The two ways in which plant cells use the sugar made in photosynthesis are C. to supply the plant with energy for life and D. to make other types of organic molecules.

C. to supply the plant with energy for life: The sugar produced during photosynthesis, typically in the form of glucose, serves as a primary source of energy for plant cells. Through cellular respiration, the sugar is broken down in the mitochondria, releasing energy in the form of ATP (adenosine triphosphate). ATP is the energy currency of cells and is used for various metabolic processes necessary for plant life, such as growth, reproduction, transport of molecules, and maintaining cellular functions.

D. to make other types of organic molecules: Plant cells utilize the sugar produced in photosynthesis as a building block for the synthesis of other organic molecules. Glucose serves as a precursor for the biosynthesis of complex carbohydrates, such as starch and cellulose, which are important for energy storage and structural support in plants. Additionally, the sugar is used to synthesize lipids, proteins, nucleic acids, and other biomolecules that are essential for various cellular processes, including growth, development, signaling, and defense mechanisms.

By using the sugar produced in photosynthesis to supply energy and as a source of carbon and energy for synthesizing other organic molecules, plant cells ensure their own survival, growth, and overall metabolic functions. This efficient utilization of sugars allows plants to carry out necessary processes and adapt to changing environmental conditions.

Enzyme- a substance, usually produced by plants and animals, which helps a chemical change to happen more quickly, without being changed itself. All living things have enzymes. Our bodies naturally produce enzymes.

The factors that impacts enzyme activity are:-

Temerature: Raising temperature speeds up a reaction, and lowering temperature slows down a reaction. However, very high temperatures can cause an enzyme to denature(lose its shape).

pH: When the pH value of the reaction medium changes, the shape and structure of the enzyme will change. Enzyme activity is at its maximum value at the optimum pH.

Substrate Concentration: As the substrate concentration increases so does the rate of enzyme activity. An optimum rate is reached at the enzyme's optimum substrate concentration.

The sun is Earth's primary source of external energy. It perfectly heats our planet to the point where life can flourish.

Sunlight is a clean, renewable source of energy. It is a sustainable resource, meaning it doesn't run out, and can be maintained because the sun shines almost every day.

In one second the sun converts 4 million tons of mass into energy in the form of heat and electromagnetic radiation.

The solar constant is how much sunlight power reaches the earth. On average, this value is roughly 1400 watts-per-square-meter. In terms of energy, this equates to about 1.8 × 10¹⁷ joules/second.

Out of the average, total amout of mass the sun converts to energy, the earth captures only 6.25 × 10-⁸%. This is an extremely small percentage , but if it all could be harnessed to use for our electricity needs, we would have more than enough.

Solar energy is perennial and non-polluting.

Stomata open during the day in most of the plants so automatically, respiration will slow down during the night.

The microscope is used differently when looking at objects under low power versus high power as you boost the magnification and the field of view narrows. On low power, you can make out more of an object.

The depth of focus diminishes each time you choose a greater power. As a result, at higher magnification, less of the material is in focus. The amount of light that penetrates your eye is greatest when the power is low. Resolving power, or the capability to discern two neighboring objects as distinct is diminished as you increase the power. Adjust the light to make up for the loss (sometimes called the iris diaphragm). 

The deepest attention is achieved on targets with the lowest power. The depth of focus diminishes each time you choose a greater power. As a result, at higher magnification, less of the material is in focus. Once more, this makes it simpler to focus on an object when using low power before moving to a higher power.
