Removal of gonads can not be considered as a contraceptive method...why?? |
|
Answer» Contraceptive devices are used to prevent unwanted pregnancy and to prevent the SPREADING of STDs. There are many methods, such as natural, barrier, oral, and surgical methods, that prevent unwanted pregnancy. However, the COMPLETE removal of gonads cannot be a contraceptive option because it will lead to infertility and unavailability of certain hormones that are required for normal functioning of accessory reproductive PARTS. THEREFORE, only those contraceptive methods can be used that prevent the chances of fertilization rather than making the PERSON infertile forever. thnx hope this helps uh |

Differentiation between root apex and shoot apex |
|
Answer» hy... friend.....
Shoot Apex ······························ ⇒ Primordia of the branches develop in the axils of leaves in the REGION of apex. ⇒ Branches arise exogenously. ⇒ Plastochrons or periodic cyclic changes occur on the flanks of the shoot apex. ⇒ Shoot apex changes its activity during reproductive phase. ⇒ The organization of shoot apex can be explained on the basis of tunica CORPUS theory. ⇒ Demarcation of the different regions of the meristem and its DERIVATIVES is not elaborate. Root Apex ································· ⇒ Primordia of branches develop far behind the root apex. ⇒ Branches develop endogenously. ⇒ They are not distinguishable in the root apex. ⇒ No change occurs during reproductive phase. ⇒ The organisation of root apex can be explained on the basis of HISTOGEN theory. ⇒ There is a high degree of differentiation in the meristem and its derivatives. thankyou brainy user |

What are the ethical issues of genetic engineering? |
|
Answer» Ethical Issues Transgenic biotechnology presents an exciting range of possibilities, from feeding the hungry to preventing and treating diseases; however, these promises are not without potential peril. Some of the issues that need to be considered are the following: Social Concerns If the blending of animal and HUMAN DNA results, intentionally or not, in chimeric entities possessing degrees of intelligence or sentience never before seen in nonhuman animals, should these entities be given rights and special protections? What, if any, social and legal controls or reviews should be placed on such research? What unintended personal, social, and cultural consequences could result? Who will have access to these technologies and how will SCARCE resources—such as medical advances and novel treatments—be allocated? Extrinsic Concerns What, if any, health risks are associated with transgenics and genetically modified foods?13 Are there long-term effects on the environment when transgenic or genetically modified organized are RELEASED in the field? Should research be limited and, if so, how should the limits be decided? How should the limits be enforced nationally and internationally? Intrinsic Concerns Are there fundamental issues with creating new species? Are species boundaries “hard” or should they be viewed as a continuum? What, if any, consequences are there of blurring species boundaries? Are chimeras and transgenics more LIKELY to suffer than “traditional” organisms? Will transgenic interventions in humans create physical or behavioral TRAITS that may or may not be readily distinguished from what is usually perceived to be “human”? What, if any, research in genetic engineering should be considered morally impermissible and banned (e.g., research undertaken for purely offensive military purposes) Will these interventions redefine what it means to be “normal”?

Why is the second half of a menstrual cycle called seceretory phase in human female? |
|
Answer» During the secretory phase of the uterus, the HORMONE progesterone is PRODUCED by the OVARIES. Progesterone (as well as estrogen) is SECRETED by the corpus luteum, (which means yellow BODY), which develops from the Graafian follicle. Progesterone secreted by the corpus luteum stimulates the further build-up of the cells in the endometrium of the uterus. Progesterone also stimulates the glands in the uterus to secrete substances that maintain the endometrium and keep it from breaking down. For this reason, this phase of the menstrual cycle is called the secretory phase. |

Write down th phenetic and phylogenetic classification of fungi |
|
Answer» A comprehensive phylogenetic classification of the kingdom Fungi is proposed, with reference to recent molecular phylogenetic analyses, and with input from diverse MEMBERS of the fungal taxonomic community. The classification includes 195 taxa, down to the level of order, of which 16 are described or validated here: Dikarya subkingdom NOV.; Chytridiomycota, Neocallimastigomycota phyla nov.; Monoblepharidomycetes, Neocallimastigomycetes class. nov.; Eurotiomycetidae, Lecanoromycetidae, Mycocaliciomycetidae subclass. nov.; Acarosporales, Corticiales, Baeomycetales, Candelariales, Gloeophyllales, Melanosporales, Trechisporales, Umbilicariales ords. nov. The CLADE containing Ascomycota and Basidiomycota is classified as subkingdom Dikarya, reflecting the putative synapomorphy of dikaryotic hyphae. The most dramatic shifts in the classification relative to previous works concern the groups that have traditionally been included in the Chytridiomycota and Zygomycota. The Chytridiomycota is retained in a restricted sense, with Blastocladiomycota and Neocallimastigomycota representing segregate phyla of FLAGELLATED Fungi. Taxa traditionally placed in Zygomycota are distributed among Glomeromycota and several subphyla incertae sedis, including Mucoromycotina, Entomophthoromycotina, Kickxellomycotina, and Zoopagomycotina. Microsporidia are included in the Fungi, but no further subdivision of the group is proposed. Several genera of 'basal' Fungi of uncertain position are not placed in any higher taxa, including Basidiobolus, Caulochytrium, Olpidium, and Rozella. |
