Description of Concept Human brains consist of two halves, and these two halves, or hemispheres, provide different functions for the person. On the left side, our brain handles numbers, logic, words, analysis, and linear sequences. We might call this the “rigid” or calculated side of the brain. On the right...

Meiosis is a scientific process where eukaryotic cells divide themselves to produce gametes for sexual reproduction. During the process of meiosis, the DNA-carrying cell divides itself twice- meiosis I and meiosis II- to produce four gametes. These gametes have distinctive features. This is because during Meiosis there is crossing over...

Animal organs are composed of various types of tissues. In their turn, tissues are composed of cells. This paper explores different types of animal tissues and discusses a variety of cell types that make up these tissues. The four basic types of tissues in animals are: epithelium, nervous, connective, and...

Macrophages are a critical factor within the immune response. Their ability to engulf and degrade target molecules is a main component of the innate immune response. Modulation to the site of tissue damage (inflammation), occurs through the process of signaling via cytokines. In addition, structural changes are induced through triggering...

Declarative memory is a type of long-term memory that can be consciously recalled. It involves things like names and places and those of specific events. An example of a declarative memory is that of the human vocabulary, which can be classified as part of the semantic memory subtype (Nevid, 2011)....
