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.
What are the functions of 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.

Wilhelm Wundt
The late 19th century marked the start of psychology as a scientific enterprise. Psychology as a self-conscious field of experimental study began in 1879, when German scientist Wilhelm Wundt founded the first laboratory dedicated exclusively to psychological research in Leipzig.
Wilhelm Maximilian Wundt (1832–1920) is known to posterity as the “father of experimental psychology” and the founder of the first psychology laboratory (Boring 1950: 317, 322, 344–5), whence he exerted enormous influence on the development of psychology as a discipline, especially in the United States.

Describe how elements form bonds?
Investigate how valence electrons related to chemical bonds?
Differentiate between ionic and covalent bonding?
THANK YOU:3
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.

how does the skeletal system and the muscular system use energy
Answer:
Vertebrates move by the actions of muscles on bones. Tendons attach many skeletal muscles across joints, allowing muscle contraction to move the bones across the joint. Muscles generally work in pairs to produce movement: when one muscle flexes (or contracts) the other relaxes, a process known as antagonism.
