Answer: A freely falling body exhibits non-uniform motion. Its velocity increases at a constant rate, so it shows uniformly accelerated motion.

ame planet is farther the the thus, the Kepler's second law tells us that a planet does and less when the planet is farther away from the sun. A planet 3. Kepler's third law states that: The cube of the mean distance of a planet from the sun is directly proportional to the square of time it takes to move around the sun. This law can be expressed as : or or where mean distance of planet from the sun and time period of the planet (around the sun) Though Kepler gave the laws of planetary motion but he could not give a theory to explain the motion of planets. It was Newton who showed that the cause of the motion of planets is the gravitational force which the sun exerts on them. In fact, Newton used the Kepler's third law of planetary motion to develop the law of universal gravitation. This is discussed below.

Following 1. Down syndrome , Trisomy of 21 " Chromosome : Down syndrome is a disorder arising due to chromosomal abnormality. This is the first discovered and described chromosomal disorder in human beings. This disorder is characterised by the presence of 47 chromosomes. It is described as trisomy of the 21 1s chromosome. Infants with this disorder have one extra Therefore they have 47 chromosomes instead of 46. Children suffering from Down's syndrome are usually mentally retarded and have a short lifespan. (Mental retardation is the most prominent characteristic. Other symptoms include short height, short wide heck, flat nose, short fingers, Scanty hair, single horizontal crease on palm. and a life expentancy/ of about 16-20 years. 2. Turner syndrome (Monosomy of chromosome): As with autosomes, abnormalities in sex chromosomes also cause some disorders. Turner syndrome (or ) arises due to either inheritance of only one chromosome from parents or due to inactivation of the gender-related part of X-chromosomes. Instead of the normal condition, women suffering from Turner syndrome show a condition. Such women arelsterile i.e. unable to have children due to improper growth of the reproductive organs. 3. 3.

" Which largle molecule breates into smalland olecule beacome big or Making \$ breaking of Molcur organum, which means instrument or engine, and the suffix "-elle" which means small. These are submicroscopic components of the cell with specific functions. Let's study about some major cell organelles found in a cell. Endoplasmic Reticulum (ER) Endoplasmic reticulum occurs in most types of eukaryotic cells except for red blood cells and spermatozoa. The endoplasmic reticulum (ER) is a type of organelle in the cells which has an interconnected membranous network of flattened, membrane-enclosed sacs or tube-like structures known as cisternae. It is distributed throughout the cell. The membranes of the ER are continuous with the outer nuclear membrane at the inner end, and at its outer end is connected with the cell membrane. There are two types of the endoplasmic reticulum, which differ in both structure and function. They are: (a) Rough Endoplasmic Reticulum (RER): The surface of the rough endoplasmic reticulum is studded with the protein manufacturing ribosomes, which give it a rough or granular appearance. Hence, it is referred as rough endoplasmic reticulum and is the site of protein synthesis. (b) Smooth Endoplasmic Reticulum (SER): The smooth endoplasmic reticulum consists of tubules, which are located near the cell periphery. This network increases the surface area for the storage of key enzymes and proteins. It synthesizes lipids and steroids. It also helps in cellular transport by forming transport vesicles. These are more abundant in the area close to plasma membrane. Nuclear envelope Nuclear pore Smooth endoplasmic reticulum
