32.2.2 Segmentation allowed for redundant systems and improved locomotion Hox genes cause segmentation development 2 advantage of Hox genes Highly segmented animals‚ usually have nearly complete set of organs in theirs each segment of body. This result to less damage in their body‚ since other segment duplicate the damage segment functions Locomotion is more efficient‚ since partitions isolate the segment can contract and expand autonomously. 32.3.

Biology coursework The aim of this experiment is to investigate the affect of pH on the enzyme amylase. The amylase is used to break down the polysaccharide starch. Amylase is a digestive enzyme classified as a saccharidase (an enzyme that cleaves polysaccharides). It is mainly a constituent of pancreatic juice and saliva‚ needed for the breakdown of long-chain carbohydrates (such as starch) into smaller units. Amylase is also synthesized in the fruit of many plants during ripening‚ causing them

Week 2 Discussion 1 The Daoism (Taoism) Legalism and the Confucianism all came from the same belief of peace and accord in the society of the Chinese. Legalism wanted a strong political body for a solution of the troubles in contemporartt society. But Confucianism and Daoism (Taoism) a strong political entity was not what they had in mind. They were opposed to that idea. Whereas legalism had believed with having striated laws and also punishments were preconditions in having a strong

2.7.- COMPARACION ENTRE LAS CELULAS Recuerda que las celulas procarionticas son celulas primitovas que no tienen organelos rodeados por membranas. 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
