photosynthesis equation with explanation
The photosynthesis equation is as follows:
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
★ Carbon dioxide + water + energy from light produces glucose and oxygen
What is photosynthesis ?
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
More to know :-
There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. They both follow very similar principles, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.
Explanation:
6CO2+ 6H2O sunlight and chlorophyll C6H12O6+ 6O2
it's a type of nutrition in which green plant manufacture their food using carbon dioxide and water in present of sunlight and chlorophyll
A student is investigating the effect of light intensity on the rate of photosynthesis . She observes that as light intensity increases the rate of photosynthesis increases. Which explanation best describes how the rate of photosynthesis can affect the biodiversity of an area?
Explanation: If the rate of photosynthesis increases, then the number of bubbles will increase.
Photosynthesis forms oxygen gas which is utilized by the animals during respiration. As the rate of photosynthesis increase with the intensity of light, the biodiversity of an area also keeps on increasing.
What is Photosynthesis?
Photosynthesis is the process by which plants produce their food with the help of sunlight, carbon dioxide, and chlorophyll, which traps the sunlight (solar energy) in the leaves of plant. This process produces sugar (food) and oxygen gas as by-product.
The oxygen gas produced in this reaction is utilized by other organisms for respiration. The organisms use oxygen gas and release carbon dioxide which is used by the plants.
As the intensity of light is increased, the rate of photosynthesis also increases which will lead to more production of oxygen gas. This oxygen will help other animals in respiration .Thus, the biodiversity of an area will increase with the rate of photosynthesis.
Apart from this, plants also provide food to the animals therefore, the more the number of plants, more will be the animals and hence increase in biodiversity of an area.

Why is algal bloom around the edges of the Black Sea than spreading all over it?
Answer:
Algal bloom. Bright green blooms may also occur. These are a result of blue-green algae, which are bacteria (cyanobacteria). Some algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants.

In a species of walruses, tusk size is controlled by a single gene that has only two alleles. The same species lives on two different sides of the Arctic Ocean. On one side, the amount of ice is much thicker and requires for walruses to have longer tusks to move out of the water. On the other side, the ice is not as thick and walruses have shorter tusks. Which of the following best describes the walruses in the two populations?
Adaptive alleles that are beneficial in one environment can be deleterious in another, due to selective pressures.
The species will eventually develop an intermediate tusk size in both populations.
The alleles of both populations will undergo directional selection to have the similar gene pools.

Various species of the flowering plant of the genus Chrysanthemum have 18, 36, 54, 72, and 90 chromosomes. The variation is likely due to polyploidy.
What is polyploidy?Polyploidy can be defined as the number of complete sets of chromosomes in a given cell of an organism.
A diploid organism contains two complete sets of homo-logous chromosomes in its somatic cells.
Many organisms used polyploidy as an evolutionary strategy for adaptation to challenging environmental conditions.

During photosynthesis, how is energy converted within the cell?.
Answer:
During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP.

Assume that each finch comes from a large population of similar finches
in its particular environment. Imagine a drought in the environment of
Finch 1 makes the small seeds they normally feed off of scarce. Describe
how natural selection could cause the population of finches in the first
group to evolve over time to resemble the population of Finch 2.
Directional selection increased the frequency of individuals carrying the larger beaks and decreased the frequency of individuals carring small beaks.
What is directional selection?
Directional selection is a way in which natural selection acts by increasing the proportion of individuals with an extreme phenotypic trait.
This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
How natural selection could cause the population of finches 1 to evolve over time to resemble the population of Finch 2?
In the exposed example, after the drought there were almost no seeds available for finch 1 to feed.
The introduction of a new allele to the population (by mutation or genetic flow) might have produced a few individuals with beaks similar to the one of Finch 2.
This beak was better for feeding. So individuals carrying this beak increased their fitness.
With time, the average size of the beaks was larger. The trait modification was related to the availability of only larger seeds with thick husks.
Eating large seeds with medium or small-sized beaks was impossible, so Finches needed to adapt, developing larger beaks to break bigger and harder seeds and eat the content.
Directional selection was responsible for the rapid change in the finches' beaks size after the drought.
The evolutive force modified the allelic frequencies, increasing the frequency of genetic variants that expressed the larger beak size and declining the frequency of the alleles that expressed smaller beak size.
