Analytical and numerical findings show that (1) perfectly synchronous intermittent reproduction does not evolve; (2) if the fruiting cost of female flowers Rc is sufficiently large and the pollen limitation 尾 is intermediate, annual reproduction does not evolve; (3) under conditions (2), sex ...
Why is it important that telomeres be lengthened? Why do all flowers produce pollen, but not all produce nectar? Why is rotation of crops essential in a farm? Why is it important to inoculate only a single tube per organism when performing the MRVP tests? Why is it important for us to ...
Why are pollen grains produced in enormous quantities in maize? Why is MALT considered strategically placed? Why is it important to eat a balanced snack? Why are sticky ends important to gene splicing? Why does the Hermann Grid illusion occur?
In October of 2020,Hossenfelder declaredthat libertarian free will—i.e., the “I-could-have-done-otherwise-using-my-volition” form—didn’t exist. I agree with her, of course, for we’re both “naturalists” and “hard determinists.” If you think matter obeys the laws of physics, ...
"What I was trying to do was cross-pollenate a Gibson with a Fender, because I love the vibrato bar," Van Halen said in an interview withGuitar World. "I didn't have the money, and the guitar I wanted to play didn't exist. It was that simple." ...
But without those challenges your immune system does not develop properly. It does not have to deal with infections and diseases. As a result it is miscalibrated. It does not learn to distinguish real threats from things like cat dander or pollen because it never really has to deal with any...
Extreme stress, such as excessive heat within a specific window, first makes plants male-sterile, while female organs remain functional and can receive wind-borne pollen from any of the few nearby stress-tolerant individuals. Thus stress-induced male sterility enables and/or enhances outcrossing in...
(body bristles), resulting in few pollen grains being transported. But bees groom themselves, and some ants are as hairy as bees. The ‘antibiotic hypothesis’ is the most accepted explanation for ants’ unsuitability for pollination. Most ant species feature a specialised gland located in the ...
does not exist for human consumption,it is essential to the insects.Honeybees store honey in their hives (蜂巢)in order for the bees to have energy for their flight muscles and for heating the hive during the winter period.They collect pollen (花粉)which supplies protein for ...
