Hunters and gatherers, because of lower caloric intake, have fewer children, and more years in between them, whereas agricultural families tend to, between nutrition and necessity, pop out a massive number of children and then the mom ends up menopausal by 30, assuming she survived having a dozen babies.. Betina wrote on April 8th, 2010 what is indigestible about spouted hulless oats, and btw, quinoa is not a grain but a seed and is highly digestible if sprouted
For those questions that you answered incorrectly, re-read those questions and the answer choices and logically determine why you answered incorrectly and justify the reason for the correct answer. It is important to understand how many questions you will be answering, develop a time limit to answer all questions, and how to break down each question into its critical parts
In organisms with external fertilisation, zygote is formed in the external medium (usually water), whereas in those exhibiting internal fertilisation, zygote is formed inside the body of the organism. When two parents (opposite sex) participate in the reproductive process and also involve fusion of male and female gametes, it is called sexual reproduction
Cyanobacteria (blue-green algae) Unlike other photosynthetic bacteria, cyanobacteria use chlorophyll a (as do plants) use water as the source of electrons to reduce CO2 to carbohydrate (because they have photosystem II as well as photosystem I). Clostridia are the only Gram-positive bacteria that have photosynthetic members and because the photosynthetic apparatus in all photosynthetic Gram-negative bacteria is in the inner membrane, perhaps the actinobacterium was the host and the clostridium the endosymbiont
Infective causes (i.e. : living organisms)
Dermatocentor venustus, wood tick) : a reddish brown tick that is responsible for transmitting Rickettsia rickettsii, Colorado tick fever virus, and Francisella tularensis to humans and for causing tick paralysis in Rocky Mountain and western areas of the USA and Canada. The Breteau index (BI) is the total number of water containers having larvae or pupae of Aedes aegypti per 100 houses inspected : in some countries BIs higher than 100 are not exceptional
Carbon is the fundamental building block of all the organic compounds needed by living things, including nucleic acids, carbohydrates, proteins and fats. For example, Neisseria meningitidis ferments glucose and maltose, but not sucrose and lactose, while Neisseria gonorrhoea ferments glucose, but not maltose, sucrose or lactose
*Author Richard Louv is the author of The Nature Principle: Human Restoration and the End of Nature-Deficit Disorder and Last Child In The Woods: Saving Our Children from Nature-Deficit Disorder. For example, diatoms, a type of protist, serve as the main base of the food chain in both fresh water and ocean habitats, supplying calories to larger protists which are then eaten by small animals, and so on
CBSE Papers, Questions, Answers, MCQ ...: Diversity In Living Organisms - CBSE - Class 9 - Science (CH7)
http://cbse-notes.blogspot.com/2012/11/diversisty-in-living-organisms-cbse.htmlWhat happens to similarities among organisms as we go from top to bottom level? Answer: Classification systems as proposed by Linnaeus use a hierarchical system in which organisms are placed into groups, at different levels, according to the features they share. Q9(NCERT): What is the primary characteristic on which the first division of organisms is made? Answer: Cell design is the basic characteristic of first division of organisms
homeobox: Homeoboxes are relatively short (approximately 180 base pair) sequences of DNA, characteristic of some homeotic genes (which play a central role in controlling body development). (Less formally, according to Medawar's definition, a virus is "a piece of bad news wrapped in a protein.") vitamin A: A member of a chemically heterogeneous class of organic compounds that are essential, in small quantities, for life
25 years does not make me infallible, true, but it certainly gives me extensive knowledge and training and the ability to back up what I say with facts. I happen to eat the diet I support because I put my money where my mouth is, and the blood test results I had done in July 2012 and again about 2 weeks ago prove you are completely wrong, you big-headed idiot
In edited prose three-fourths of the clauses in which which is the relative pronoun are restrictive: A novel which he later wrote quickly became a bestseller. used with a noun in requesting that its referent be further specified, identified, or distinguished from the other members of a class: which house did you want to buy? (as pronoun): which did you find? (used in indirect questions): I wondered which apples were cheaper 2
In the process of evolution cells have developed different features that have helped them to survive in different environments and to use different sources of energy. There are thousands of types of bacteria that have been scientifically described and classified and probably as many that are still waiting for their turn
