Hence, Option B is correct.

Hence, Option B is correct.

Between 5 and 78:
First number = 6
Last number = 72

Hence, Option D is correct.

Banks primarily engage in the collection of deposits and the distribution of loans. These functions are crucial for managing the financial transactions of individuals, businesses, and the overall economy.

Ashoka the Great embraced Buddhism and played a significant role in spreading it to Central Asia, West Asia, and Sri Lanka.

Chordates are characterized by the presence of a notochord.

Volume of the cylinder = πr²h = 1232


Hence, Option A is correct.

Static electricity pertains to the accumulation of electric charges on the surface of materials or substances.

A sector is region which lies between an arc and two radii joining the extremities of the arc and the centre.

The shaded region denotes the sector of a circle. The unshaded part is also a sector.

Notice that it is enclosed by two radii and an arc.

We have a=2, d=6-2=4
l=a+(n-1)d
210=2+(n-1)4
208/4=n-1
n=53rd term

The bar graph shows decline in the number of tigers .

Depth of well(h) = 14m
radius of well(r) = 2m

Inner surface area of well(like a cylinder) = 2πrh 

surface area= 2 x 22/7 x 2 x 14 = 176 m²

cost of cementing = ₹2 per m²

Total Cost = 176 x 2 = ₹352

3. 1.5

Solution: Let the radius of curvature of the convex surface of the plano-convex lens be RRR. The focal length of a concave mirror is related to the radius of curvature by f=R2f = \frac{R}{2}f=2R​.

1. When the plane side is silvered, the system behaves as a concave mirror with focal length 30 cm. The effective focal length fefff_{\text{eff}}feff​ of this system can be found using the mirror formula and lens formula combined, but given the scenario, we focus on this system.

2. When the convex side is silvered, the system behaves like a concave mirror with focal length 10 cm.

By using the relations for combined focal length and refractive index of the plano-convex lens, and applying these boundary conditions, the refractive index nnn of the material of the lens is determined to be 1.5.

As qvB = mv²/r

Breeder hen diets should be supplemented with Vitamin K to ensure good chick health. Laying hens fed a diet deficient in vitamin k produce eggs low in the vitamin, and when the eggs are incubated, the chicks produced have low reserves and a prolonged clotting time. Vitamin A  is easily destroyed in feed processing and storage. Usually, 10,000-15, 000 IU/ kg vitamin A is supplemented in broiler or broiler breeder commercial feed. High levels of vitamin A decreased egg production, size, and hatchability in laying hens.

Gibberellins promote cell division in plants.

The rough endoplasmic reticulum (ER) is called 'ro... moreugh' because it has organelles called ribosomes attached to the surface.Ribosomes are the organelles that turn mRNA into proteins. These proteins are initially long strings of amino acids. This string has to be folded in the right way to form a functional protein. The rough ER helps with the folding of these amino acid-strings and at the same time prevents their degradation by enzymes in the cell.

The fluid-filled balloon inside the cranium acts as a shock absorber for the brain, absorbing impact forces and reducing the risk of damage to the brain tissue during sudden movements or external impacts. This protective mechanism helps safeguard the brain from injuries that could impair its vital functions.

Placenta is the part that provides nutrients to the growing fetus inside the uterus.
Explanation:
The placenta is an organ that develops during pregnancy and is attached to the inner wall of the uterus. It acts as a connection between the mother and the fetus, providing essential nutrients and oxygen to support the growth and development of the fetus.
Key Points:
- The placenta is responsible for exchanging nutrients and waste products between the mother's blood and the fetus's blood.
- It allows the transfer of oxygen, glucose, amino acids, vitamins, and minerals from the mother's bloodstream to the fetus.
- The placenta also filters out waste products such as carbon dioxide and urea from the fetus's blood, which are then eliminated by the mother's body.
- It produces hormones that help maintain the pregnancy, such as human chorionic gonadotropin (hCG), progesterone, and estrogen.
- The placenta also acts as a protective barrier, preventing harmful substances from reaching the fetus.
- It continues to grow and develop throughout pregnancy, ensuring a constant supply of nutrients and oxygen to support the fetus's growth.
In conclusion, the placenta plays a crucial role in providing the necessary nutrients for the growing fetus inside the uterus.
