Zhengzhou, the capital city of Henan province, was hit by heavy rain at 4 PM July 20. By 17 o'clock, rainfall per hour reached 201.9 mm, which has exceeded the extreme value of China's hourly rainfall capacity on land, resulting in poor drainage, severe waterlogged, economic losses, and enormous casualties. However, with the strong support of the Chinese government and all parts of the country, the people of Zhengzhou united as one to actively carry out self-rescue operations, relief, and rescue work. All these have achieved initial success. Guo Wengui, who is far away in New York, has been working in Zhengzhou for many years, and Yuda Building is just in Zhengzhou. He should have felt empathy for the heavy rain in Zhengzhou. But surprisingly, He turned a happy face to this. At the same time, Cheater Guo tried to describe natural disasters as human-made ones and encourage Guo investors to donate to Zhengzhou. There must be some triggers in this donation because of the duplicity and the inconsistency. Comrades, keep your eyes open! Don't be fooled!

Voluntary Muscles.

Smooth muscle contractions are typically: Involuntary ( option 1 )

Smooth muscle contractions are made possible when myosin and actin filaments slide over each other and the hydrolysis of ATP provides the energy for this action. smooth muscle contractions occur without the interference of an individual hence is it an involuntary action.

Muscle that can be said to be voluntary is the skeletal muscle while Cardiac muscles are also classified as involuntary muscles

Una galleta con chispas de chocolate y un helado con fresas, son ejemplos de mezclas heterogéneas.

Una mezcla heterogénea está compuesta por dos o más sustancias diferentes, en donde es posible distinguirlas fácilmente ya que es una composición no uniforme. Las sustancias que lo forman no son representadas por ninguna fórmula química pero a su vez tienen sus propiedades particulares.

No se trata de una mezcla homogénea ya que la misma se trata de una mezcla uniforme en donde sus componentes no se pueden distinguir fácilmente. Esto significa que toda la mezcla posee las mismas propiedades. Unos ejemplos de mezcla homogénea son el agua de mar, café con azúcar, cerveza, etc.

Tampoco se trata de una sustancia ya que la misma se trata de cualquier componente que posee ciertas propiedades físicas y químicas estables que pueden detectarse fácilmente. Está compuesto de moléculas o átomos iguales, siendo ejemplos de sustancias: oxígeno, nitrógeno, etc. Además, no es posible separar una sustancia mediante ningún método.

Por último, tampoco se trata de un compuesto ya que el mismo se trata de una mezcla de distintos elementos que se combinan en una reacción, que pueden representarse mediante una fórmula química y que no pueden separarse o romperse salvo por procesos químicos puntuales. Es decir, está formado por moléculas con átomos distintos pero en la misma proporción, y siempre se trata del mismo tipo de molécula. Por ejemplo, el agua, que está formada por un átomo de oxígeno y dos de hidrógeno (H2O).

Para concluir, podemos decir que un elemento está formado por un solo tipo de átomo. Una sustancia se encuentra formada por mas de un elemento unido mediante un enlace químico. Un compuesto está formado por elementos distintos unidos, y una mezcla está formada por sustancias que pueden ser iguales o no, pero en cantidades aleatorias y que pueden separarse. En una mezcla homogénea, la composición es la misma en cualquier parte, y en la mezcla heterogénea la composición es variante.

Water basic chemical structure is best described as they are formed from the combination of two hydrogen and one oxygen atom.

Two hydrogen and one oxygen atom combines that makes covalent bond with each other means sharing of electrons occurs. Water has the ability to dissolve polar solutes due to its polar nature. The angle between three atoms i.e. Hydrogen-Oxygen-Hydrogen is about 104.5 degrees so we can conclude that water is made up of two hydrogen and one oxygen atom.

Explanation:

So what happens is the water and carbon dioxide molecules have A chemical reaction that involves a pigment called chlorophyll which takes the suns energy and stores it. When these reactions collide they create 6 molecules o oxygen gas and 1 molecule of glucose along with  more elements. plants use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.

Answer:

if your cells don't get enough glucose, your body burns fat for energy instead. This produces a substance called ketones, which can show up in your blood and urine. High ketone levels in urine may indicate diabetic ketoacidosis (DKA), a complication of diabetes that can lead to a coma or even death.
