Male System The structure and function of the human male reproductive system‚ is very similar to that of many other mammals. The male system is designed to make sperm or male gametes and is adapted to provide for the delivery of these gametes to the female to allow for fertilization. Male Reproductive System Male Reproductive System Structures 1. testes -- produces sperm and the hormone testosterone 2. scrotum -- pouch enclosing the testes keeping the sperm at an optimum temperature

FlexCon is a company that prides itself on the quality of its pistons. Lately they have been relying on suppliers for major components while manufacturing simple items with relatively small differentiation. By doing this‚ too much of their talent is going to waste leaving them with a big decision of whether to keep outsourcing or to insource. They are already heavily dependent on suppliers for critical components. The cost it takes to insource is greater than the cost to outsource but deciding to

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.

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
