Describe why the amount of light available to the Chlorella culture might affect the growth dynamics of the alga.
-Dominant- [34]

Answer:

See the answer below

Explanation:

The amount of light available to Chlorella culture might affect the growth dynamics of the alga <u>because the light is an important factor necessary for the synthesis of carbohydrates and other important molecules in the body of the organism.</u>

The process of synthesizing carbohydrates is termed photosynthesis and during this process, the energy of light is used to excite the photosystem of the chlorophyll of the organism, leading to the release of electrons whose energy is used to synthesize an energy molecule that is utilized in the latter part of the photosynthetic process. The entire process of photosynthesis can be summarised as an equation below:

            6CO_2 + 6H_2O + light --> C_6H_1_2O_6 + 6O_2

<em>The manufactured carbohydrates act as food for the organism and are broken down during respiration to release energy necessary to drive metabolic processes that bring about growth and development.</em>

Hence, the amount of light is an important factor that might affect the growth dynamics of all green plants, including the Chlorella.

Mademuasel [1]

Approximately  10% of the stored energy of  an organism at  one level of a food web is transferred to the tissue of the organism that consumes it at the next level of the food web.

<h3>What is food web and its importance ?</h3>

A food web consists of all the food chains in a single ecosystem. Each living thing in an ecosystem is a part multiple food chains. The importance of food webs is to describe feeding relationship among species in a community.

On an average only about 10 percent of energy stored as biomass in a trophic level is passed from one level to the next.

Meiosis does PMAT twice! That means there is a prophase I and a prophase II. There is a metaphase I and a metaphase II. Etc… If
AURORKA [14]

Answer:

If there is homologous chromosomes (metaphase I) or duplicated chromosomes/sister chromatids (metaphase II) in the middle of the cell.

Explanation:

Meiosis involves two series of nuclear divisions grouped into meiosis I and meiosis II. Each division has the same number of stages i.e prophase, metaphase, anaphase, telophase etc. Meiosis I involves the separation of homologous chromosomes i.e similar but non-identical chromosomes from each parent.

On the other hand, meiosis II involves the separation of sister chromatids (duplicated chromosome). Since METAPHASE is generally characterized by the alignment of chromosome at the middle of the cell for separation in the anaphase stage, it means that the difference between metaphase in meiosis I and II will be whether it is homologous chromosomes that are in the middle or sister chromatids.

Therefore, according to this question, I would know if the cartoon is in metaphase I or II if:

- there are homologous chromosomes in the middle of the cell (metaphase I)

- there are sister chromatids in the middle of the cell (metaphase II).
