This hypothesis, known as Baker’s Law or Baker’s Rule13, may apply to natural long-distance dispersal events as well as to species introduced by humans to new regions, because suitable mates and/or pollinators
Spores thus differ from gametes, which are reproductive cells that must fuse in pairs in order to give rise to a new individual. Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction. ... Many bacterial spores are highly durable and can germinate even afte...
Algae are capable of reproducing through asexual or vegetative methods and via sexual reproduction. According to the authors of "Algae," asexual reproduction involves the production of a motile spore, while vegetative methods include simple cell division (mitosis) to produce identical offspring and the...
(b) What are three fungal interactions with humans? Differentiate between molds, yeasts, and dimorphic fungi and summarize the structure and function of fungal hyphae. How do slime molds differ from true fungi? What makes a fungus different from a plant or an animal? What makes them different...
Fungi tend to reproduce sexually when (a) food is particularly abundant (b) food supply is depleted (c) rain is plentiful (d) threatened with a fungicide (e) they have completed 50 generations of asexual reproduction. Haustoria are modified nutri...
Would this have indicated that the beavers were the “guilty party”, or would it have simply indicated that humans and some animals in this area were infected with similar genotypes of Giardia? And what of disease potential? Although the infected humans in this 1976 outbreak were obviously ...
There are over 200 million reported cases of malaria each year, and most children living in endemic areas will experience multiple episodes of clinical disease before puberty. We set out to understand how frequent clinical malaria, which elicits a strong

Rhythmic reproductive cycle in female primates (Monkeys, apes, humans etc.) is called menstrual cycle. The first menstrual cycle (Menarche) that begins at puberty. It is repeated after an average interval of 28/29 days. Release of one ovum takes place in the middle of each menstrual cycle....
