experimentation‚ usually to ensure whether a product is safe for humans or not. However‚ animal testing is used worldwide‚ and its purpose ranges from guaranteeing the safety of domestic products to aiding medical research‚ particularly in the areas of biology and chemistry. This has always been a very controversial issue‚ but it first became a concern of Great Britain when in 1822‚ the country passed the Martin’s Act‚ which outlaws farm animal cruelty.

consists of the interactions among plants‚ animals‚ soil‚ water‚ temperature‚ light‚ and other living and non-living things. The word environment is used to talk about many things. People in different fields of knowledge (like history‚ geography or biology) use the word differently. An electromagnetic environment is the various radio waves that equipment such as radio and radar can meet. Galactic environment refers to conditions between the stars.

working in a group of people you come up with things for your experiment as in what procedure you’re creating. During your collaborations you discover things that happen as a whole instead of as an individual. An example of collaboration was during biology we came up with ideas to create a procedure for the gummy bear lab as a class to get the same data Communications is defined by talking with others about the information you gathered. When communicating with people you putting the information from

Su material nuclear se encuentra flotando en el citoplasma. Las bacterias se clasifican como procariontas. Las celulas eucariontas son las mas avanzadas y contienen organelos rodeados por membranas. Su material nuclear esta rodeado por una membrane nuclear. Las celulas de las plantas‚ los hongos y los animals son eucarionticas. Las celulas de las plantas

Our assignment is about how chromosomes separate and how cell division works through microtubules and histones. DNA in the nucleus is loose and not well defined into chromosomes because it is usually tightly coiled‚ but in the interphase nucleus the chromatin exists in two forms: loosely coiled form called euchromatin and tightly coiled formed called heterochromatin. These two types become more coiled to form the chromosome at the time of cell division. DNA is a bit loosely coiled in the euchromatin

9.16 Explain why human skin coloration is not sufficiently explained by polygenic inheritance. -Polygenic inheritance is the additive effects of two or more genes on a single phenotypic characteristic. 9.17 Describe the limits‚ benefits‚ and ethical challenges of genetic testing. -Genetic testing can fall into one of the five categories: carrier testing‚ diagnostic testing‚ prenatal testing‚ newborn screening‚ and predictive testing. Carrier testing is designed to determine whether a person

There are many differences between photosynthesis and cellular respiration. Photosynthesis requires energy as photons. Cellular respiration supplies energy in the form of ATP. In photosynthesis‚ electron transport occurs in the membranes of chloroplasts or thylakoid discs. Cellular respiration takes place in the membranes of mitochondria. In photosynthesis‚ water breaks down to supply 2 electrons and 2 Hydrogen ions and release ½ O at the beginning of the chain. In cellular respiration‚ 2 electrons
