What type of pressure system usually brings cloudy, stormy, or 'lousy'
weather?
Answer:
Low Pressure System
Explanation:
Low Pressure System is a region where the atmospheric pressure is lower than that of surrounding locations.
Low pressure because that sucks the surrounding air in creating a "mushroom cloud" of air and water vapour. This then cools and condenses creating clouds and rain.
Which of the following is not true about water?
A Its smallest form is a molecule.
B It’s made of two different elements.
C It has the same charge throughout.
D It occurs both inside and outside of the human body.
Answer:
Im pretty sure everything but C is correct...
Water is a compound whose molecule is made up of two elements, namely hydrogen and oxygen. Because of the different atoms, the charge throughout is not the same. Thus, the correct option is C.
The molecule of water contains three atoms in total, two of hydrogen and one of oxygen. It is represented chemically as H₂O.
Because of the difference in the atoms, there is also a charge that is formed due to the difference in the electronegativity of oxygen and hydrogen atoms.
As a result. the electrons are more pulled towards oxygen andthus, oxygen has a more negative charge and hydrogen has a more positive charge.
Thus, the charge is not distributed throughout evenly. Thus, the correct option is C.

(a) The oscilation in the pressure inside arteries and arterioles is called by the cardiac rythm. During ventricular systole the pressure rises and during ventricular diastole it decreases
(b)Because when referring to capliaries there is a smaller diameter in the cross section but the surface is bigger. This means that the pressure decreases and the blood has a steady flow instead of periodic bursts.

A jar contains several different types of atoms. The proportions of these atoms can be changed slightly without changing any substance in the jar. This jar contains
Answer:
a mixture
Explanation: A mixture consists of different atoms that are not chemically bonded. It is of two types of the heterogeneous mixture and homogeneous mixture. The chemical substances can be differentiated visually in the heterogeneous mixture.
In a mixture, the proportion of atoms can be slightly changed without changing or modifying any substance. This is because the individual substances in mixture keep their properties when mixed together. Further, mixtures have variable compositions and substances. these mixtures can be are separated using physical methods.

radium in an element found in group 2 and period 7. in a normal radium atom, how many energy levels contain at least one atom?
A. 1 B.6 C.7 D.8
Answer:
the answer is d
Explanation:
In a normal radium atom, there are 7 energy levels.
The periodic table is arranged in groups and periods. The elements in a group have the same number of valence electrons while the elements in the same period have the same number of energy levels.
Radium is an element in period 7. The fact that it is in period 7 implies that it has 7 shells or energy levels. Hence, in a normal radium atom, there are 7 energy levels, each containing electrons.

They share genetic traits. The current organisms were once members of the same species as them. It is believed they just evolved.
What is extinct organisms?A species is considered extinct when there are no longer any surviving examples of it anywhere on the planet. This can happen with both plants and animals. An organic byproduct of evolution is this. However, sometimes extinctions happen far more fast than usual. The primary contemporary causes of extinction include habitat destruction and loss, mostly due to deforestation, overexploitation via overhunting and overfishing, invasive species, climate change, and nitrogen pollution.
