Hi there!
In the experiment we can identify the variables to determine if the result of the experiment is sound.
Dependent variable - Growth of plants
Independent variable(s) - Medium of watering, being talked to and not talked to
In an experiment you want to have 1 independent variable to determine if that 1 variable is influencing the dependent variable. Because there are two independent variables in this experiment, it is impossible to tell which one caused the plants that were talked to to grow more. As a result, the correct answer would be...
B. Talking to plants may or may not help plants grow faster because the amount of water given was likely different for each group.
I believe it’s 50%, it’s either 50% or 75%
Answer:
Negatively.
Explanation:
A decrease in biodiversity can cause a large chain reaction within the ecosystem. A loss of species can be detrimental, especially if they're key stone species. This negative impact can cause the food chain to be disrupted which ends up affecting every organism within the environment. Every organism plays a role within the ecosystem and when one or more are removed it causes extreme disarray.
Answer:
Because each daughter cell must contain an equal and correct amount of genetic material (DNA)
Explanation:
Mitosis and Meiosis are both types of divisions that cells undergo. They both involve the production of new daughter cells. Each cell contains the information needed by it for its life processes. This information is stored in the genetic material known as DNA.
However, when a cell divides during mitosis and meiosis, two and four new daughter cells results respectively. These daughter cells need to contain the genetic material (DNA) that stores the genetic information needed for their survival. The cell ensures that each daughter cell that will result from the process of mitosis and meiosis contains this genetic material by undergoing a process called DNA REPLICATION before the start of the divisions (mitosis and meiosis).
DNA replication is the process of doubling or duplicating the information in the DNA. Hence, at the end of the replication process, the cell contains two copies of the genetic material (DNA) which separates into the daughter cells equally during cell division (mitosis and meiosis).
Protein synthesis does not need DNA replication as it involves using the information in the genetic material (DNA) to synthesize useful products (protein).
