Kidneys.Acute kidney failure (AKF) occurs when there is a sudden reduction in kidney function that results in nitrogenous wastes accumulating in the blood (azotemia). If untreated, uremia can cause coma & eventually death. The accumulation of nitrogenous wastes is known as uremia.
Mammary Gland.The female reproductive hormones, estrogens, progesterone, & prolactin, have a major impact on breast cancer & control postnatal mammary gland development. Optimal mammary growth requires both estrogen & progesterone.
. 12. LDC, DEO & PA/SA Exam, 06.2016 TF No. 1375232) The main sugar found in milk is known as lactose, which is a natural sugar that is made up of glucose & galactose. It provides a mildly sweet taste to milk. It makes up around 2-8% of the solids in milk. Lactase, found in the small intestine, breaks down lactose into two simpler forms of sugar: glucose & galactose, which is then absorbed by the body.
The reason the ocean is blue is due to the absorption & scattering of light. The blue wavelengths of light are scattered, similar to the scattering of blue light in the sky but absorption is a much larger factor than scattering for the clear ocean water. In water, absorption is strong in the red & weak in the blue, so red light is absorbed quickly in the ocean leaving blue. The red, yellow, & green wavelengths of sunlight are absorbed by water molecules in the ocean.
Xerophyte.Cactus is a xerophyte as it specializes in surviving in hot & dry environments. Xerophytes are plants that are adapted to survive in an environment with little water, such as a desert or an ice- or snowcovered region in the Alps or the Arctic.
single-stranded RNA.AIDS viruses have single stranded RNA. The single-stranded RNA is tightly bound to nucleocapsid proteins. It is composed of two copies of positive single-stranded RNA that codes for the virus's nine genes enclosed by a conical capsid composed of 2,000 copies of the viral protein.
Charles Darwin had proposed 'theory of Evolution'. The theory of evolution came into view by the reawakening of ancient materialistic philosophies & became widespread in the 19th century. This philosophy supposes that matter is absolute & infinite. This materialistic philosophy does not hold anything to be real except the matter, so it tries to explain the universe & nature through purely material factors.

Spirogyra.Pond silk is the common name of Spirogyra (algae) as it is very slimy in shape. Its filaments shine like silk due to the presence of mucilage. It is also known as pond silk, water silk, pond scum or mermaid's trees as of its bright green silky appearance.
Trochodendron.Trochodendron is a genus of flowering plants with one living species. Fewer than 200 species of angiosperms have the primitive feature of vesselless wood. It is vesselless angiosperm. With two exceptions - Trochodendron & Tetracentron-, all vesselless angiosperms occur in the Magnoliidae.
Tier-I (CBE) The bitterness can be tasted at the posterior part of the tongue. Bitter taste is one of four taste receptors of the tongue. It used to be thought that they were situated toward the back of the tongue.
number of chromosomes.An organism having more than two sets of homologous chromosomes is known as polyploid & the phenomenon polyploidy. Polyploidy may occur due to abnormal cell division, either during mitosis, or commonly during metaphase I in meiosis.Polyploidy refers to a numerical change in a whole set of chromosomes.
B. average life-span of a red blood cell in humans
C. the period of menstrual cycle soon after menstruation, during which fertilisation is most likely to occur
D. period of completion of one schizogony cycle of malarial parasite inside a red blood cell
Answer & Explanation
Answer : Option
the period of menstrual cycle soon after menstruation, during which fertilisation is most likely to occur.The menstrual cycle is the scientific term for the physiological changes that occur in fertile women & other femaleprimates for the purposes of sexual reproduction. 28 days to complete although this does vary from person to person. It takes approx. Length variation between eight & 20 days is considered as moderately irregular cycles. Variation of 21 days or more between a woman's shortest & longest cycle lengths is considered very irregular
Blood.Thalassemia are forms of inherited autosomal recessive blood disorders that originated in the Mediterranean region. Whilst possessing the ability to cause significant complications, including anaemia, iron overload, bone deformities & cardiovascular illness, thalassemia may confer a degree of protection against malaria, which is or was prevalent in the regions where the trait is common. In thalassemia, the disease is caused by the weakening & destruction of red blood cells.
