D A-ii,B-i,C-iv,D-iii

The correct answer is:
A-iv,B-iii,C-ii,D-i

Solution:
An isothermal process is the one during which the system's temperature remains constant. So change in internal energy is zero. And work can be calculated as

W=-nRTlnVfVi
An isobaric process is the one during which the system's pressure does not change.

So, work done will be W=-P×ΔV
An isochoric process is the one during which the system's volume does not change. due to which work done is always zero. so, according to the first law of thermodynamics. q=∆U
An adiabatic process is the one during which no heat is transferred to or from the system, i.e., ΔQ=0 . Hence, W=∆U

Placenta	The placenta is connected to the embryo through an umbilical cord which helps in the transport of substances to and fro from the embryo. Placenta also acts as an endocrine tissue and produces several hormone-like human chorionic gonadotropin (hCG), placental lactogen (hPL), estrogens, progestogens, etc.

Zona pellucida	The secondary oocyte has a new membrane called Zona pellucida surrounding it. This thick coat of zona pellucida is composed of glycoproteins and synthesized by the oocyte. Later, the granulosa cells lying in close vicinity of the ovum and zona pellucida become elongated to form the corona radiata.

Bulbourethral glands	The bulbourethral glands also called Cowper’s glands located in the membranous urethra, also opens into the urethra and secrete clear mucus for lubrication and alkaline fluid that neutralizes the traces of acidic urine in the urethra.

Leydig cells	The regions outside the seminiferous tubules called interstitial spaces contain small blood vessels and interstitial cells or Leydig’s cells. Leydig cells constitute the endocrine tissue of testis. Leydig cells synthesize and secrete testicular hormones called androgen. Androgens are a group of male sex hormones mainly testosterone.

These muscles are made up of many muscle fibres that contain many myofibrils. These contain many units known as sarcomeres which are the main unit of muscle contraction. Sarcomere extends between two Z lines or krause's membrane. I bands or Isotrophic bands or Light bands are bisected by these Z lines and A bands or Anisotrophic or Dark bands lie in the centre. Hensons zone or H zone is seen traversing the dark bands.

Solution:
(a) Diabetes insipidus is not related to diabetes mellitus (type 1 and type 2 diabetes). Diabetes insipidus is caused by problems related to antidiuretic hormone (ADH) or its receptor and causes frequent urination. Hence, Insulin is related to Diabetes mellitus.
(b) Thyroxin- Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. The goiters caused by an overactive thyroid or hyperthyroidism.
(c) Addison's disease is caused by damage to your adrenal glands, resulting in not enough of the hormone cortisol and, often, not enough aldosterone as well. All treatment for Addison's disease involves hormone replacement therapy to correct the levels of steroid hormones your body isn't producing. Some options for treatment include oral corticosteroids.
(d) Acromegaly is a hormonal disorder that develops when your pituitary gland produces too much growth hormone during adulthood. When this happens, your bones increase in size, including those of your hands, feet and face. Acromegaly usually affects middle-aged adults.
