Do bacteria have genes for genetic exchange? The idea that the bacterial processes that cause genetic exchange exist because of natural selection for this process is shared by almost all microbiologists and population geneticists. However, this assumptio
Why do people (and most other species) have two copies of each chromosome? How are these two copies similar? How are they different? a. Explain how bacteria reproduce. b. Which factor do they rely...
How many chromosomes do bacteria have? How many copies of a gene do somatic cells have? Do humans get 1/4 of their DNA from their grandparents? How many alleles does a person have? How are human mitochondria inherited? The typical human cell contains how many chromosomes? What percentage of...
aWhy do humans, virtually alone among all animal species, display a distinct left or right handedness? Not even our closest relatives among the apes possess such decided lateral asymmetry, as psychologists call it. Yet about 90 per cent of every human population that has ever lived appears to...

For Botrytis stem rot, candidates with high efficacy belonged to genera or species of bacteria or fungi known from literature for antagonism against plant pathogens such as Pseudomonas sp. (Haas & Défago, 2005), Lysobacter sp. (Postma et al., 2009), Chryseobacterium sp. (Kim et al., ...
Not all birds sing, but several thousand species do. They sing to defend their territory and croon (柔声唱) to impress potential mates. “Why birds sing is relatively well-answered,” says Iris Adam, a behavioral neuroscientist. However, the big question for her was why birds sing so much...
Not all birds sing, but those that do—some several thousand species—do it a lot. All over the world, as soon as light filters over the horizon, songbirds start singing. They sing to defend their territory and to impress potential mates. “Why birds sing is relatively well-answered,” ...
In 2001, after 10 years of research, a complete human genome was published for the first time. Even though genetic technologies have become much cheaper, faster, and better since then, sequencing the DNA of a species still remains a challenge. Each year, new animal genomes are being studied...
As functional foods, they are also anti-inflammatory and known to modulate gut bacteria [25]. Species-specific structural and maturation elements of fruiting bodies and mycelia, and potentially even the fermented substrate from which the prepared product may have been produced, impact effects. ...
