Answer:
In a chemical reaction, only the atoms present in the reactants can end up in the products.
Explanation: No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
Answer:
1 so that all parts of the plants and animals Get Enough nutrients and oxygen
2 the pigment called haemoglobin makes it red
3 waste products such as urea will cause great harm to the body is not excreted
4 the heart pumps blood the blood contains nutrients and oxygen facial transported to other organs so that the cells can operate
5 transpiration is the loss of water by plants. it helps with cooling down the plant after photosynthesis. Just the Way We sweat
6the stomata opens and closes to allow water to pass through it therefore transpiration occurs
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:
they are so for..
both of them are comprised of similar tissues working together to perform a particular task.
<span>It began with selective breeding in the ancient times where a population with desirable traits were bred with other population to achieve a desired set of traits. It then continued with the advance in the discovery of bacteria (Escherichia coli) and antibiotics. Then Watson and Crick discovered the structure of DNA. The latest advance being that of gene sequencing and gene editing tools. </span>
