summer s the pleasantest season. At this time of the year everything is neat and clean‚ the days are long. In the summer the heat can be unbearable and there can be hardly a breath of air. But at this time of the year the hot sun ripens the corn and fruit. There are plenty of strawberries‚ cherries‚ currants‚ gooseberries‚ raspberries‚ apricots‚ peaches‚ plums and blackberries‚ which are ripe and afford a treat for the old and the young. And what pleasure can compare with that of watching the glorious

In this lab students were instructed to cause micro evolution in a population of fruit flies “Drosophila melanogaster”. This organism was chosen for a number of different

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

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
