It has been stigmatized as result of its higher prevalence among the youths.
Answer:
Thyrocalcitonin or TCT
Explanation:
Thyrocalcitonin or TCT is a non-iodinated calcium lowering hormone. It is originating from the parafollicular cells or C cells (C for calcium).
The thyroid gland consists of follicles of cuboidal epithelial cells. These cuboidal cells have a nucleus at the base. These are principal cells responsible for the synthesis of thyroid hormones.
In between these follicular cells, other high cuboidal cells are present, known as parafollicular cells / C cells. These cells synthesise the hormone TCT. When there is high levels of calcium ions in the serum, TCT will release. This lowers the high level of calcium ions in the blood and plasma to normal level. This is done due to the deposition of calcium in the bone.
All options above are potential benefits of planting only native species when implementing rain gardens, no-mow native meadows, and/or tree plantings.
<h3>What are native species?</h3>
Native species are species that evolved in a particular environment and therefore they are well adapted to it.
Native plants are well know to be more adapted to survival and do not need extra watering to survive.
In conclusion, all options above are potential benefits of planting only native species when implementing rain gardens, no-mow native meadows, and/or tree plantings.

The change in chemical composition of interstitial fluid affects the oxygen and nutrients transportation to the cell, and also removal of waste from the cell.
Interstitial fluid- Extracellular fluid is mostly made up of blood plasma and interstitial fluid. Interstitial fluid is the substance that fills the spaces between cells. Salts, water, cellular waste products, coenzymes, hormones, carbohydrates, fatty acids, and amino acids make up its composition.
Chemical Composition- The chemical composition of a material refers to the configuration, proportion, and kind of atoms in chemical substance molecules. The chemical makeup will alter when substances interact. For instance, when hydrogen and oxygen combine, water is produced.

Answer:
Please find the detailed explanation of this statement below
Explanation:
Firstly, a repressed gene is a gene whose expression has been inhibited or repressed. The lac operon in E.coli bacteria is a regulatory unit containing structural genes, a single promoter and operator regions. The promoter is the region where the transcription enzyme (RNA polymerase) binds to in order to transcribe the genes in the lac operon. The structural genes in the lac operon can only be expressed in the presence of lactose sugar.
However, in the absence of lactose, LAC REPRESSOR, which is a transcription factor (protein), prevents the binding of RNA polymerase to the PROMOTER region by binding to the OPERATOR region of the lac operon. This inhibits the expression of the lactose genes in the operon.
Note that, the structural genes in the lac operon (lacZ, lacY, lacA) code for proteins that help break down lactose sugar for energy in the E.coli bacteria. Therefore, a bacteria cell with a repressed lac operon will be unable to degrade lactose sugar.
