The purpose of this lab is to examine cross sections from the leaves of C3 and C4 plants and to determine the morphological differences between them while relating those differences to their metabolism. In C3 plants the carbon dioxide is first incorporated into a 3-carbon compound. Their stomata are open during the day and photosynthesis takes place throughout the mesophyll cells. In comparison C4 plants, the CO2 is first incorporated into a 4-carbon compound. Their stomata are open during the day and photosynthesis takes place within the inner cells.…
Skin – *The skin of pigeon like any other vertebrate composed of two layers – outer epidermis and inner dermis. *Epidermis is ectodermal in origin while dermis is mesodermal in origin. *Epidermis is in turn made up of two layers viz. , stratum corneum and stratum germinativum or profoundum. *Stratum corneum is multilayered, outer part of epidermis which is keratinized without any uni or multi cellular gland cell.…

Mitochondria: - The site of aerobic respiration where ATP (cellular energy) is produced. - They are 0.5-1.5 µm wide and 3-10 µm long. 2) Lysosome: - Contains digestive enzymes which are kept separate from the cytoplasm by the surrounding membrane, but can be used to digest invading cells or break down worn out components of cell. - Its size is 0.5-5 µm in diameter.…
We as a group decided that we needed to divide and conquer, however, have the other individual in the group go back over and edit the other’s work where need be. We will both be able to work on different aspects of each assignment in order to gain both of our perspectives. We are also aiming to complete the final project before the final week in order to be able to complete…
In the BIO 14 Lab, we attempted to design a oviposition experiment that would tell us something about the relative behavior of two variants of a beetle species Callosobruchus maculatus (SI – originating from South India & BF – originating from Burkina Faso). The specific question being asked in our experiment is: How does the availability of the preferred bean type affect the oviposition strategy (measured by the number of eggs on each bean) of female SI and BF beetles? Most of our group members actually arrived this question at first independently and upon further discussion found that we all were looking to answer the same question. I arrived at this question as when looking that preferred seed of the two beetle types were so vastly energetically…

In “House of the Red Fish” Tomi and Keet were enemies in the story. After all, Tomi was Japanese, Keet was caucasian, and the Japanese had just bombed Pearl Harbor. After those event happened Keet became the bully but Tomi was still an innocent kind hearted boy. The first of Tomi and Keet’s adversaries were their family’s reputations.…

First, what worked well was how our group integrated our individual skills together to complete the project. When we introduced ourselves and what our concentrations were, it was easy to determine what roles and responsibilities we would take on. We worked individually on our tasks before meeting together and integrating everything into the final product. The problems that arose primarily concerned communication and scheduling group meetings.…
Fig. 1. Various nuclear changes of erythrocyte in the blood smears of fish treated with sub-lethal concentrations of profenofos such as (a) control (regular cell), (b) micronucleus, (c) bi-nucleus, (d) degenerated nucleus, (e) notched nucleus, (f) nuclear bridge, and (g) nuclear bud. Two groups of fish were exposed to 10% and 50% of LC50 of profenofos for 7, 15, and 30 days, while third group treated as control (0% profenofos). Three slides were prepared for each fish and 2000 cells were scored from each slide and at least five fish analyzed in each group.…
When I return to school after summer break I will take AP Biology 2. I enjoyed my experience with Honors Biology so I decided to continue it at a higher level. In order to properly introduce myself I will be discussing my family, my previous science courses, and my purpose and goals in taking this class. I am a only child and have a small family.…

Sabrina Wu 7/9/15 Biology Ability to Perceive Through Time Biology Summer Assignment Precognition is the gain of knowledge obtained through extrasensory means. The majority of precognitive experiences come from extrasensory perception (ESP), also known as the sixth sense. ESP uses methods such as card reading and dreams. It can also be experienced through trance, channeling, and mediumship.…
