Umbilical cord is found in the foetus of amniotes (RAM- Reptiles, Aves, Mammals) in mammals umbilical cords called as umbilical vesicle. Umbilical artery carries oxygenated and vein carry deoxygenated blood.
The umbilical cord is a tube that connects you to your baby during pregnancy. It has three blood vessels: one vein that carries food and oxygen from the placenta to your baby and two arteries that carry waste from your baby back to the placenta. The umbilical cord is a narrow tube-like structure that connects the developing baby to the placenta. The cord is sometimes called the baby's “supply line” because it carries the baby's blood back and forth, between the baby and the placenta.
7. B
Renin and erythropoietin are secreted by kidney. Renin hormone controls the secretion of aldosterone and it also converts angiotensin to angiotensin-I and helps in RAAS system. Erythropoietin stimulates RBC formation. Vitamin-d/calciferol promotes absorption of calcium and phosphate.
Renin, enzyme secreted by the kidney (and also, possibly, by the placenta) that is part of a physiological system that regulates blood pressure. In the blood, renin acts on a protein known as angiotensinogen, resulting in the release of angiotensin I.
1. Actinomycetes: Bacteria and Fungi
During prophase I, the chromosomes have already duplicated. During prophase I, they coil and become shorter and thicker and visible under the light microscope. The duplicated homologous chromosomes pair, and crossing-over occurs. Crossing-over is the process that can give rise to genetic recombination. At this point, each homologous chromosome pair is visible as a bivalent , a tight grouping of two chromosomes, each consisting of two sister chromatids. The sites of crossing-over are seen as crisscrossed non-sister chromatids and are called chiasmata. The nucleolus disappears during prophase I. In the cytoplasm, the meiotic spindle, consisting of microtubules and other proteins, forms between the two pairs of centrioles as they migrate to opposite poles of the cell. The nuclear envelope disappears at the end of prophase I, allowing the spindle to enter the nucleus.
The structural formula of sulphur dioxide is SO2, and its a covalent planar molecule which is V−shaped with an angle of 120 degree.
Sulphur dioxide as oxidising agent :
Claus Process : SO2 + 2H2S (Hydrogen sulphide) ⟶ 3S (elemental sulphur) + 2H2O
Sulphur dioxide as reducing agent :
SO2 + Cl2 ⟶ SO2Cl2 (sulphuryl chloride)
14. A
By convention, the three primary colors in additive mixing are red, green, and blue. In the absence of light of any color, the result is black. If all three primary colors of light are mixed in equal proportions, the result is neutral (gray or white). When the red and green lights mix, the result is yellow. When green and blue lights mix, the result is a cyan. When the blue and red lights mix, the result is magenta.
15. A
Isothermal process :- Temperature remains constant (i.e.ΔT=0)
Adiabatic process :- It is the process in which heat is not exchanged by system with the surroundings (i.e. Q=0).
Free expansion :- In free expansion, the gas expands freely. Which means that the volume change is zero. So work done is zero. Also the heat transferred is zero, as the both chambers are insulated (i.e. Q=0)
Cyclic :- It is a process in which the initial & final states of the system are the same.

Connecting link is an organism having characteristics of two different group of organisms e.g, duck-billed platypus ( scientific name Ornithorhynchus anatinus) is a connecting link between reptiles and mammals i.e, it has mammary glands to feed its young ones like other mammals e.g human being, cow, buffalo etc., and it lays hard-shelled egg with a large amount of yolk like reptiles , so duck-billed platypus is a connecting link between two evolutionary groups viz., reptiles and mammals.1.

Leptotene stage is the first phase of Prophase I of meiosis I where the chromosomes appear to be thin thread like structures called as Bouquet. The correct sequence of prophase-I of meiosis is Leptotene, zygotene, pachytene, diplotene, diakinesis.During prophase I, the chromosomes have already duplicated. During prophase I, they coil and become shorter and thicker and visible under the light microscope. The duplicated homologous chromosomes pair, and crossing-over occurs. Crossing-over is the process that can give rise to genetic recombination. At this point, each homologous chromosome pair is visible as a bivalent , a tight grouping of two chromosomes, each consisting of two sister chromatids.

XXY= Klinefelter’s syndrome; XYY= Jacob’s syndrome.
A webbed neck, or pterygium colli, is a congenital skin fold that runs along the sides of the neck down to the shoulders. There are many variants. It is a feature of Turner syndrome (only found in girls) and Noonan syndrome.Turners syndrome is a genetic disorder in which the female lacks an X-Chromosome. The condition is represented as 45-X or 45-X0, that is out of 46 chromosomes, one X chromosome is missing. The females with turner's syndrome have less intelligence than the average females of their age. The symptoms may vary within different individuals, low set ears, webbed neck, short stature, swollen hands are the typical characteristics of Turners syndrome.

A liquid is found to scatter a beam of light (due to Tyndall effect) but leaves no residue when passed through the filter paper (as the size of the particles is smaller than the pores of the filter paper). The liquid can be described as a colloidal sol. Tyndall effect (optical property) is the scattering of light by the colloidal solution when a beam of light is passed through a colloidal solution. Tyndall effect is not shown by true solution as well as suspension. Brownian movement is the zig zag motion of colloidal particles. Brownian movement is not shown by ordinary suspension. Size of particles suspension > colloid > solution. Colloidal Sulphur is used as germ killer. The purification of blood in the body is called Dialysis.12. C

Explanation: A function or mapping (Defined as f:X->Y) is a relationship from elements of one set X to elements of another set Y (X and Y are non-empty sets). X is called Domain.
Explanation: A function or mapping (Defined as f:X->Y) is a relationship from elements of one set X to elements of another set Y (X and Y are non-empty sets). X is called Domain.
A function can be one to one or many to one but not one to many.
A function f:A->B is surjective (onto) if the image of f equals its range.
If f is both surjective and injective, we can say f is bijective.
If f and g are onto then the function (gof) is also onto.

Let a and b be two real positive and unequal numbers and let A,G,H be arithmetic, geometric and harmonic mean respectively between them.Then, A>G>H.
Relation between AM,GM and HM is: AM × HM = GM^2

n(n+3)=n2+3n+2−2=(n+1)(n+2)−2≡even−even≡evenSince for any natural number n, (n+1)(n+2) will always be an even number.
OR
OR
We know there are two types of natural numbers even and odd
Case 1. If n is even then n+3 will be odd
Thus n(n+3)= even × odd = even
Case 2. If n is odd then n+3 will be even
Thus n(n+3)= odd × even = even
Hence n(n+3) will always be even number
Thus n(n+3)= even × odd = even
Case 2. If n is odd then n+3 will be even
Thus n(n+3)= odd × even = even
Hence n(n+3) will always be even number
