Answer:
Some of the environmental issues that are related to agriculture are climate change, deforestation, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
Explanation:
Answer:
By using carbon-14 in the experiment in order to prove the statement.
Explanation:
Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.
Answer: Option C
Explanation:
Amino acids are the polymers that leads to the formation of the polymer proteins. The amino acids are joined together by the polypeptide bond.
In case of sugars the simple sugars are joined together by the glycosidic bond to form a more complex structure known as starches. The simple sugars are easily digested and are less complex in terms of bonding and structure.
Answer:
They have tissues, organs, and organ systems.
Explanation:
While all animals are multicellular, heterotrophic, eukaryotic and ingest their food, not all animals have tissues, organs, and organ system.
<em>The simplest group of animals, the sponges, are made up of several cells that have minimal interaction with one another. Hence, while sponges are multicellular, they are not at tissue level of body organization.</em>
All the options are true for all animals except the last option.
