Answer : 4. "flat, convex"
Explanation :

Flat Mirror (or Plane Mirror): Reflects light without distorting the image. The image formed is erect (upright) and of the same size as the object, but reversed from left to right.

Convex Mirror: Also produces an erect image. The image formed is virtual (cannot be projected onto a screen), smaller than the actual object, and upright.

Both flat and convex mirrors can create upright (erect) images of real objects.

Answer : 3. "tentacles"
Explanation :

Actually, the locomotor part of a hydra is not its tentacles. Hydras move by a remarkable way called "looping." They attach one end of their body to a surface and then release the other end, allowing it to move and attach again. This looping movement is facilitated by the contraction and expansion of the body, rather than the use of tentacles. Tentacles are specialized structures primarily used for feeding and defense in hydras.

Answer : 4. "due to tapetum lucidum"
Explanation :

Cats (and many other animals) have a layer of cells behind their retinas called the tapetum lucidum. This layer enhances night vision by reflecting light that passes through the retina back into the eyes. When light enters the eye, some of it is absorbed by the retina's cells, allowing the brain to process visual information. However, the tapetum lucidum reflects the remaining light back through the retina, giving the photoreceptor cells a second chance to detect the light. This reflection of light enhances their night vision capabilities and is what causes a cat's eyes to appear to glow in the dark or in low light conditions.

Answer : 4. "from monkey"
Explanation :

The term "Rh factor" is derived from the Rhesus monkey, in which the protein was first discovered. The Rh factor is a protein that can be present on the surface of red blood cells, and it is named after the Rhesus monkey because the protein was initially identified in Rhesus monkey blood during scientific experiments. The Rh factor is an important component in blood typing and can be either Rh-positive (presence of the protein) or Rh-negative (absence of the protein) in humans.
