Chloe reads that given the correct conditions, cuttings from certain plants will form roots along the stem, enabling a new plant
Archy [21]

Answer:

The correct answer is - If you use the rooting hormone when cloning plants from cuttings, then it will be beneficial for the cuttings.

Explanation:

A hypothesis is a possible explanation or solution behind the particular natural world process or phenomenon. It is formed on the basis of the observation of the phenomenon or process, how it works or what characteristics it shows.

In this study, it is found that the root hormones promote the growth in the clonings from the cuttings of plants thus, the provided hypothesis is the correct hypothesis for the experiment given.

Can you identify the process by which natural selection acts on an insect population exposed to pesticides?
NeTakaya

Identify the process by which natural selection acts on Change in Population the surviving insects reproduce. The frequency of resistant insects in the population increases.

  • Pesticides are any poisonous substances that are employed to kill animals, fungi, or plants and cause financial loss to crops or ornamental plants or pose a risk to domestic animals' or humans' health.
  • A pesticide is used on an insect population. Some insects possess a trait that renders them pesticide resistant. These flies remain. Without the gene, insects perish.
  • Insects that are still alive reproduce. Insects that are resistant are becoming more prevalent. Ecological Change Insecticide is used on a population of them.
  • Choosing Pressure Some insects have a trait that renders them pesticide resistant. These bugs are persistent. Without the gene, insects perish.

The bacterial transduction experiments done by Hershey and Chase, and the bacterial transformation experiments done by Griffith,
Katarina [22]

Answer:

Hershey Chase  and Griffith experiment supported the same conclusion which was: DNA is the molecular substance of genetic inheritance.

Explanation:

Both experiments have was based on different phenomenon and techniques to prove same conclusion.

Hershey and chase conducted an experiment via bacteriophage which consists to DNA and protein coat that infects bacterial cells. He proved the DNA as genetic material by the help of transduction mechanism (Incorporation of Bacteriophage DNA in to bacterial cells). He used two group of Bacteriophage 1st group of Phage contain radioactively labelled proteins by Sulphur 32 isotope. While 2nd group contain Bacteriophage having P32 labelled DNA to infect Bacterial cells. After the infection, the Reaction tubes subjected to centrifuge and presence of radioactivity was determined in pellet and supernatant. The 1st group show radioactivity in supernatant while 2nd group shows racdioactivity in pellet or bacterial cells.

Griffiths just hypothesized a substance that can be transmitted from dead organism to alive organisms with the help of transformation phenomenon (uptake of Genetic material from the surrounding or environment). He conducted his experiments on <em>Streptococcus pneumonia avirulent and virulent species. </em>By mixing dead virulent species and live avirulent species and injecting into the mice results in the death of an experimental animal. While alone dead virulent species and live avirulent species fail to cause disease in mice.

A. Did not refer to the source of the information in the body of the post

Explanation:

In the post written by his friend, we can see that he decided to write information about the periodic inspections carried out by the United States Department of Agriculture as well as by the Food and Drug Administration, because he read about these inspections somewhere. However, he forgot to show this place where he read this information, that is, he forgot to present the source where he got the information presented in the post. By presenting the source, it would make the post more trustworthy and relevant.
