They are called B.) Organs .
My reason being is because organs are your kidneys , lungs, and etc.
Cells are not tissue but they are what runs through your blood.
and Systems build up all of those , Organs are a group of things that work together to function a specific part .this is what works together to perform the same functions.
I really hope this helps you a lot :)
Answer:
the magnifying glass showed scientists that plants were made up of cells
✅ the microscope enabled scientists to discover single-celled organisms
the microscope showed that cells of plants and animals have different structures
the telescope enabled scientists to see objects they could not view before
Almost all living creatures on our planet depend on plants for food and oxygen, either directly or indirectly. So, if all the plants disappeared, eventually so would almost all the other life. Also, Earth would be hotter.
Answer:
Gene therapy is a medical field which focuses on the utilization of the therapeutic delivery of nucleic acids into a patient's cells as a drug to treat disease.
Answer:
d. Genes that play a role in the same metabolic pathway are organized into an operon.
Explanation:
In prokaryotic organisms like bacteria, polycistronic mRNAs exist which means that each gene does not have a separate promoter of its own. In fact many genes are under the control of a single promoter. These genes being a part of same metabolic pathway are organized into an operon. For example, lac operon and tryptophan operon. In lac operon, three genes named as β-galactosidase, permease and transacetylase are expressed under a single promoter which is known as lac promoter.
In contrast to this, in eukaryotes the mRNAs are monocistronic i.e. only a single gene is controlled under a single promoter.
