A. gravitational pull
B. eye
C. updraft
D. fog
Plz Help!!! God Bless You
Winds blowing in opposite directions form a cylinder that might get tipped up by a supercell’s updraft.
What do you mean by updraft?Updrafts are found when a wind blowing at a hill or mountain has to rise to climb over the hill. Updrafts can also be caused by the sun heating the ground. The heat from the ground warms the surrounding air, which causes the air to rise. The rising pockets of hot air are called thermals.
The definition of an updraft is a strong upward current of air. When a big gust wind comes along and catches on the umbrella on your outside table from underneath, knocking your umbrella and table over with its power, this big gust of wind is an example of an updraft.
When warm, moist air moves upward in an updraft, puffy cumulus clouds may form in the atmosphere. The moisture in the air condenses into water droplets as it rises. The cloud will continue to grow as long as warm air from below continues to rise.

Hope this helps!
Measure the volume of a balloon filled with room temperature air; place the balloon in a freezer for an hour and measure its volume again would best investigate the effect temperature has on the volume of a gas. So, the correct option is C.
How volume effect the temperature of the gas?The ideal gas law states that the temperature of a gas is directly proportional to its volume. Specifically, the temperature of a gas will increase if its volume is decreased while its volume and pressure remain unchanged. If the volume of a gas is increased, its temperature will fall but its volume and pressure will remain unchanged.
This relationship can be explained by the fact that when a gas is compressed (that is, its volume decreases), the molecules are confined to a smaller area and move more away from each other and the walls of the container. Bars collide. Due to the increasing frequency of impacts, there is also an increase in kinetic energy, which increases the temperature.
So, the correct option is C.

Cyanobacteria can cluster together into colonies called _______, with some discovered in Western Australia that are 3.5 billion years old. Cyanobacteria produce oxygen and convert sunlight to energy using _______. Plants and arthropods didn't make the transition to land until near the end of the _______ Period. Diverse multicellular eukaryotes didn't appear until the _______ period. A large multicellular eukaryote requires more _______ to survive than a single-cell eukaryote. Respond to the following based on your reading. Describe the biological chemical processes that were responsible for producing oxygen in Earth's atmosphere, eventually leading to the Cambrian Explosion. Explain the importance of oxygen in the evolution of large multicellular animal life.
Answer:
1.) stromatolites
2.) photosynthesis
3.) Ordovician
4.) Cambrian
5.) oxygen
6.) As Earth cooled, carbon dioxide dissolved in the early ocean. Cyanobacteria consumed carbon dioxide and converted it to oxygen. Methane was removed from the atmosphere as oxygen was produced, eventually leading to the Cambrian Explosion.
7.) Metabolic processes that use oxygen produce more energy than anaerobic metabolism. Simple diffusion of oxygen would limit the size of a multicellular eukaryote, but animals evolved ways to transport oxygen to their tissues, which permitted an increase in size.

C
Explanation:
Many kinds of air pollution can't be seen, which means A is incorrect. Any kind of pollution can be harmful to you, which means B is incorrect too. Air pollution is very harmful but in most cases can't be directly seen, so C is correct. Pollution can be found everywhere, so D is incorrect also.
You have colonies growing on a culture and are going to identify them. First, you do a Gram stain and viewing it on 1000x magnification, you see Gram positive cocci, no predominating arrangement. What test should you do to determine if it a staphylococcus or a streptococcus
Answer: The test that's should be done to determine if it's a staphylococcus or a streptococcus is a BIOCHEMICAL TEST known as CATALASE TEST.
Explanation:
In the laboratory diagnosis of microbiology samples, GRAM STAINING technique is used to identify bacteria pathogens in specimens and cultures by their gram reactions. The bacteria may be either gram positive or gram negative.
Gram positive bacteria when views with ×100 oil immersion stains dark purple with crystal violet and are not decolorize by acetone or ethanol. Examples of gram positive bacteria include:
--> Staphylococcus
--> Streptococcus
--> Clostridium
--> Corynebacterium
Since a gram positive cocci was identified without a predominating arrangement, further biochemical test known as catalase test should be carried out to determine if the cocci is staphylococcus or a streptococcus.
CATALASE TEST is used to differentiate those bacteria that produce catalase enzyme such as staphylococcus from non- catalase producing bacteria such as streptococcus. Catalase acts as a catalyst in the breakdown of hydrogen peroxide to oxygen and water. An organism is tested for catalase production by bringing it into contact with hydrogen peroxide. Bubbles of oxygen are released if the organism is a catalase producer, therefore staphylococcus but if no bubbles are observed, it's a streptococcus.

Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant
produced. THis is common in premature infants.
In healthy individuals, friction is a major factor affecting pulmonary ventilation
Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant produced. This is common in premature infants.
Explanation:
Infant Respiratory Distress Syndrome (RDS) occurs in new born infants whose lungs are unable to produce the enough surfactant to keep their lungs expanded which would enable them to breathe properly after delivery.
It is most common in premature infants because surfactant is produced in the third trimester of pregnancy so premature infants might not get the chance to produce enough before the are delivered. RDS needs to be treated as soon as possible or else a baby could suffer damage to the brain and other vital organs.

A student boiled a pot of water on the stove until there was nothing left. If he started with 100 grams of water, how many grams of water vapor did he produce?
Answer:
100 grams
Explanation:
If there is nothing left that means that all of the 100 grams have become water vapors
He produced 100 grams of water vapor in such a way that nothing was left, which means that all the water vapor of 100 grams has become.
What is Water vapor?Water vapor is also called aqueous vapor is defined as the gaseous phase of water which is a state of water within the hydrosphere. Water vapor can result from the evaporation or boiling of liquid water, or from the sublimation of ice that is transparent, as are most components of the atmosphere.
When water absorbs a sufficient amount of heat it becomes a gas known as water vapour, where the process is called evaporation. The water vapor (steam) mixes with the air and appears as water boils in a teapot and escapes into the air.
Thus, the student produced 100 grams of water vapor in such a way that nothing was left, which means that all the water vapor of 100 grams has become.
