Answer:
The one treated with DNase and protease
Explanation:
<em>The samples that will transform yellow into purple if RNA is the genetic material are the ones treated with </em><em>DNase </em><em>and </em><em>protease</em><em> respectively.</em>
<u>The treatment of the heat-killed sample of the purple life with DNase will ensure that the DNA in the sample becomes degraded while treatment with protease will ensure that protein is degraded, leaving only the RNA. Thus, the RNA can be taken up by the yellow life form and become transformed into purple if indeed RNA is the genetic material.</u>
The sample treated with RNase cannot transform the yellow life into purple because the RNase catalyzes the degradation of RNA into smaller components.
Answer:
4 red : 0 white
Explanation:
R R
r Rr Rr
r Rr Rr
Since the dominant allele is RR this means that it will always be red
The aswer is b. Vascular Cambium
it is a plant tissue which is located between Xylem and Phloem in the stem and root of a vascular plant and the source that produces Secondary xlem and phloem
Nb : Vascular Cambium does not transport waters , minerals, it only produce Xylem and Phloem which add the tree's girth
Answer:
The correct answer is - water pollution.
Explanation:
In the US, water pollution is one of the most serious ecological problems, and sedimentation by filled with dirt, slit caused by development sites or construction sites. It is caused in the name of developing cities and states for new homes and other construction that is nothing but careless development that is causing water pollution in these areas including the Virginia.
The excessive silt has covered the spawning beds of fish causes spawning of the habitat. The dirt and slit and sediments cause inhibiting light to aquatic plants that result in less oxygen and food for aqautic life.
