If a leaf appears toothed, it is a Crenate and Serrate.
Laboratory tests and clinical procedures include:
- The blood glucose test and the glycosylated hemoglobin test are tests to identify diabetes and prediabetes (A1c).
- A glucose tolerance test may be administered to you if you're expecting to check for gestational diabetes.
- Your thyroid's functionality can be determined by a number of tests, chief among them a TSH measurement.
- Other examinations can evaluate parathyroid problems.
- Female hormonal problems can be identified with the aid of luteinizing hormone (LH) and follicle stimulating hormone (FSH) blood tests.
- Male hormonal problems can be discovered with tests for total testosterone.
- Other blood tests measure hormone levels that have an impact on numerous systems, including cortisol, 17-hydroxyprogesterone, DHEA-sulfate, ACTH, aldosterone, vitamin D, PTH, prolactin, and other estrogen analogues.
- Thyroglobulin (Tg) tests can be used to track thyroid malignancy.
<h3>What is Endocrinology?</h3>
•Endocrinology is the study of endocrine glands.
•Endocrine glands are a group of glands in the body which secrete hormones.
•The purpose of the secreted hormones is to evoke a specific response in other cells of the body which are located far away.

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.
True ..In animals, the female mitotic sequence produces only one ovum; the other three haploid cells become "polar bodies".
