Answer:
The correct answer is c. detergent is used to break apart plant cells to extract DNA.
Explanation:
Here we are talking about DNA isolation in E.coli and detergent is used to break apart the bacterial cell membrane by destabilizing the cell membrane. Detergent disintegrates the proteins present in the cell membrane which causes the rupture of membrane releasing the cell extract outside the cell.
Detergent is not able to break plant cell because it is made up of cellulose and require blending or mashing. Detergent can only be used to disintegrate the cell membrane because only cell membranes contain lipids and proteins.
Hence, the correct answer is c. detergent is used to break apart plant cells to extract DNA.
A complex assemblage of animals, plants, and their environment through which materials and energy move is known as ecosystem.
<h3>What is a ecosystem?</h3>
All the organisms that live in an ecosystem are present, along with their physical surroundings. Through energy flows and nutrient cycles, these biotic and abiotic components are interconnected. Plant tissue absorbs energy from the system through photosynthesis. Animals contribute significantly to the flow of matter and energy through the system by eating plants and one another as well as.
Additionally, they affect the biomass levels of the microbial and plant communities. Decomposers help to promote nutrient cycling by transforming nutrients stored in dead biomass back into a form that can be easily utilized by plants and microbes. They do this by consuming dead organic matter and releasing carbon back into the atmosphere.

Answer: Pollution will move with water, disrupting other ecosystems.
Answer:
1.806 × 10²⁴ molecules
Explanation:
From the chemical compound given in this question, there are 3 moles of Hg(SO)4.
To calculate the number of molecules in 3 moles of Hg(SO)4, we multiply the number of moles by Avagadro number (6.02 × 10²³)
number of molecules = 3 × 6.02 × 10²³
= 18.06 × 10²³
= 1.806 × 10²⁴ molecules
These types of factors are called Constants, or controlled variables. If you have an experiment that is lacking a controlled variable, it’s near impossible to determine the outcome.
