Answer:

1. Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. ... A covalent bond involves a pair of electrons being shared between atoms. Atoms form covalent bonds in order to reach a more stable state.

2. The electrons in any given element's outer shell are its valence electrons. When elements share electrons, a strong covalent bond is formed. ... When an element gives away an outer electron, it results in oppositely charged ions that are held together by a weaker ionic bond.

3.Ionic bonds result from transfer of electrons, whereas covalent bonds are formed by sharing. 2. Ionic bonds are electrostatic in nature, resulting from that attraction of positive and negative ions that result from the electron transfer process; charge separation between covalently bonded atoms is less extreme.

Clapping your hands involves the somatic nervous system, hence option B is correct.

The knee reflex is a well-known illustration of this phenomenon. When the patellar tendon, is located just below the knee cap.

Our hands are controlled by the median, ulnar, and radial nerves. Each of these nerves controls both sensory and motor activity in various hand regions.

The peripheral nervous system includes the radial nerve. Your lower limbs, skin, internal organs, and arms and fingers all get impulses from your brain via the peripheral nervous system.

Therefore, in somatic nervous system with a reflex hammer, the quadriceps automatically contract, causing the lower leg to thrust out, hence option B is correct.

Answer:

Explanation:

In the movie Jurassic Park, the Tyrannosaurus Rex was infamously poor at detecting prey that stood still. If its eyes were anything like a human's, that must mean it had poor cornea.

Cornea is the transparent part of the eye that covers the iris and the pupil and allows light to enter the inside. Small abrasions (scratches) on the cornea usually heal on their own. Deeper scratches or other injuries can cause corneal scarring and vision problems.

Important functions of cornea in the eye include protecting the structures inside the eye, contributing to the refractive power of the eye, and focusing light rays on the retina with minimum scatter and optical degradation.

If the cornea becomes damaged through disease, infection or injury, the resulting scars or discoloration can interfere with vision by blocking or distorting light as it enters the eye.
