Repetition of properties is due to the same outer electronic configuration. OR a Define excretion. OR a The process of removing toxic waste from the human body is called excretion.

It secretes estrogen and progesterone. It holds the baby till it is ready for birth. It provides oxygen and nutrients to the foetus. It helps to remove waste also. The placenta is composed of both material tissues and tissue derived from the embryo. The chorion is the embryonic derived portion of the placenta.

It is composed of fetal blood vessels and trophoblasts which are organized into finger-like structures called chorionic villi. Name the defect of vision the boy is suffering from. State the possible causes of this defect and explain the method of correcting it. OR a Write the function of each of the following parts of the human eye : i Cornea ii Iris iii Crystalline lens iv Ciliary muscles b Why does the sun appear reddish early in the morning?

Will this phenomenon be observed by an astronaut on the Moon? Give a reason to justify your answer. This defect is caused: 1. Correction: The image of a distant object i. As the image of the object lying at infinity is not formed on the retina of the eye, so such object can not be seen clearly by the myopic eye.

The far point of such an eye is near to the eye as shown in fig. This defect can be corrected by using a concave lens minus powered of suitable focal length. So, a man suffering from this defect wears spectacles having a concave lens of suitable focal length. The concave lens diverges the rays of light entering the eye from infinity. The atmospheric refraction occurs in a medium of gradually changing refractive index.

Since the atmosphere bends starlight towards the normal, the apparent position of the star is slightly different from its actual position. Since the stars are very distant, they approximate point-sized sources of Class 8 Maths Chapter 3 Question Answer And light. As the path of light rays coming from the star goes on varying slightly, the apparent position of the star fluctuates and the amount of starlight entering the eye flickers i.

OR a i Cornea: It is a thin membrane, covering the surface of eyeball, through which light enters. It acts as a primary lens, which provides the refraction for light rays entering the eye.

The focal length of the crystalline lens is changed by the ciliary muscles. Its function is to focus the incoming light rays from the object on the retina using its refractive property. It also holds the eye lens in position. Hence, the appearance of the sun at the sunrise, near the horizon looks almost reddish. This phenomenon will not be observed by an astronaut on Moon, since there is no atmosphere so no scattering of light takes place, thus the Sun appears dark.
