Looking for updates @30112002
Is it mulberry tree?
Beautiful! A blend of Art& Science! @Shivangi
Please post updates!
Can you state some of the causes that result in seasons?
Earth’s tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun’s most direct rays. So, when the North Pole tilts toward the Sun, it’s summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it’s winter in the Northern Hemisphere.
Very good description! @Devansh
"…People cough and sneeze into the open air - and confined spaces like elevators, buses, airplanes, and offices - without realizing the consequences.
Each cough and sneeze is the natural equivalent of pushing the button on an aerosol spray can. If the person harbors disease-causing microbes, coughing and sneezing sprays them into the air, on a fine aerosol mist of saliva and mucus from the mouth and nose.
Other people inhale the droplets and the microbes. The droplets also get sprayed onto their lips and into their eyes. Mucus membranes in the nose, eyes, and mouth are main gateways through which some disease-causing bacteria infect the body.
Common colds, influenza, and SARS are among the diseases transmitted via this “airborne” route. Colds and flu cause misery for millions of people annually, with flu alone killing 26,000 Americans in a typical year. Globally, it claims an average of 500,000 people annually.
Medical textbooks list “unprotected” coughing and sneezing as major culprits in the spread of respiratory diseases. Unprotected means not covering the nose and mouth. People tolerate coughing and sneezing into the open because the consequences are hidden and remote. When someone with a respiratory disease coughs and sneezes among other people, count on one thing. In a few days, some may get deathly ill…"
We do have autmn and spring in India.
It is prominent in temperate regions of the country. Holi is a festival that celebrates spring.
Our Autumn in India does not see the
characteristic “Fall” of leaves!
@Vedikaa, I’m curious. would flowers be the only things that attract butterflies. Flowers provide nectar for the butterflies. But what about the larvae of the butterflies? How would you feed those?
What are the butterflies that are most commonly seen in your area? Can you take some pictures?
I noticed a lot of conversation on the flowering of Gul mohar and that wikipedia has got it wrong.
Here is an excerpt from “flowering Trees” - M S Randhawa, page 118.
The flowering time is April-June, with a second flush in July. Sometimes, there is a third flush coinciding with the end of the monsoon.
This is probably what needs to be edited into wikipedia. I would humbly request the person (wiki username Saivedant) who has simply changed the wiki content to “April - July” to please change it and add the citation provided here.
Well the oxygen is captured by hemoglobin in the RBCs.
The Blood contain, blood plasma and the corpuscles (cells). In the alvoeli of the lungs when we breath air. The alvoeli is surrounded by blood capillaries. These capillaries are semipermeable. First:The oxygen in the air get dissolved in blood plasma (the water part of blood). Then the dissolved oxygen is used by hemoglobin. By simple diffusion the oxygen get dissolved. As there is high concentration of oxygen in air and low concentration in blood plasma.
So, what happens in Moina when oxygen concentration is low? @Shivangi
