Explanation:
The fossils can be found on top of mount Everest due to regional uplift of the crust.
Mount Everest is located a along a convergent margin between two tectonic plate. Due to similarity in density between the two margins, when they collide, there is tectonic build up.
Sedimentary rock layers originally at sea levels are uplifted to those tower peaks as the plate continues to grind against each other.
Most sedimentary rocks contains fossils. As the grinding continues, the uplift and deformation continues.
A given mass of gas in a rigid container is heated from 100 °C to 300 °C. Which of the following best describes what will happen to the pressure of the gas? The pressure will
Taking into account the Gay-Lussac's Law, the pressure will increase by a factor less than three.
Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions against the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
In summary, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.
Mathematically, Gay-Lussac's law indicates that the ratio of pressure to temperature is constant:
[tex]\frac{P}{T} =k[/tex]
Studying two different states, an initial state 1 and a final state 2, it is satisfied:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case, a given mass of gas in a rigid container is heated from 100 ° C to 300 ° C, that is, it is heated from 373 ° K to 573 ° K. This indicates that the temperature is increasing by a factor less than three. Since pressure is directly proportional to temperature, pressure must increase in the same proportion.
Finally, the pressure will increase by a factor less than three.

What is the mass of an atom with 44 protons, 42 electrons, and 57 neutrons?
Answer:
The atomic mass is 101.
Explanation:
Protons and neutrons are the only particles that contribute to mass. Electrons do have a mass, but it's so miniscule and insignificant that it doesn't contribute to the mass of an atom. In every instance of calculating atomic mass, add the number of protons to the number of neutrons.
Therefore,
44 + 57 = 101
number of protons + number of neutrons = atomic mass
Also, there can never be a negative amount of protons or neutrons, so if you get a negative number, there's something wrong.
Bonus Information:
Don't confuse mass with charge! As it says in its name, neutrons are neutral or have no charge. Protons (+) and electrons (-) are the only particles that have a charge, so calculating that would be different.
If you were calculating the atomic charge with the same numbers, your answer would be:
44 - 42 = 2
Charge = +2
What To Remember:
M = p + n
C = p - e
C = atomic charge, M = atomic mass, p =protons, n = neutrons, e = electrons

C. on the sun, this can be accounted on the Earth's gravity
Object's weight at the sun:At 12 PM, when the Sun is straightforwardly beneath, it pulls on an item in a similar course as the draw of the Earth; around early afternoon, when the Sun is straight above, it pulls on an article toward a path inverse to the draw of the Earth.
Thus, all articles ought to be heavier around evening time than they are at the day. Sun's gravitational draw on earth-bound objects is around 0.0006 of earth's gravity.

Read the passage and examine the photos. Then, suggest two reasons that scientists think developing pollen grains made vascular plants the most successful plants that live on land.
Passage
These mosses are nonvascular plants that grow closely packed together in moist places. The sperm they produce for sexual reproduction must swim to a nearby plant that has an egg that the sperm may fertilize.
Seed plants, such as these conifers, are vascular plants that live in both moist and dry places. For sexual reproduction, conifers produce pollen grains that contain sperm that cannot swim. Conifers produce massive amounts of pollen grains that can be carried by wind.
Answer:
Vascular plants are successful due to better transportation for water, nutrients and reproduction.
Explanation:
I got it right at school and hope this helps you learn to STUDY.jk
According to scientists, the evolution of pollinators made vascular plants the most successful land plants for two major reasons:
Sperm can be more effectively and widely distributed for sexual reproduction, thanks to pollen grains.Vascular plants can reproduce without the need for a moist environment because they can make pollen grains.What are Pollen grains?Plants with seeds, including flowering plants and conifers, produce pollen grains as a component of their reproductive process. They are often carried by wind or pollinators, such as bees, to the female reproductive organs of the same or different plant species, where they can fertilize female gametes (egg cells) and begin the development of seeds.
They carry the male gametes (sperm cells) of the plant. Many plant species depend on pollen grains for successful reproduction, and these grains have evolved a variety of forms, sizes, and surface features that make them easier to disperse and be recognized by pollinators.

You are so excited-your first summer job! You are a hot-tub maintenance assistant. You travel to homes, making sure the pH of their hot-tub water is correct (between 7 and 7.6), and adjusting and cleaning when necessary. But before you get started, you need to answer the following questions. What is pH? What do you use to test it? Why would it be important to keep the pH of hot-tub water between 7 and 7.6?
Answer: well i guess we can say that is a scale used to specify the acidity or basicity of an aqueous solution and it is important to keep ph of hot tub water between 7 and 7.6 because if it is not balanced the water can negatively affect your tub.
Explanation:
pH is an extremely important chemical level to maintain in your spa's water chemistry. A high pH or a low pH will spell trouble for you and your spa. On the pH scale, a reading of 7.4-7.6 indicates perfectly balanced pH. Any number lower than 7.4 means that your water is now considered “acidic”.
Answer:
pH is a scale to measure the acidity or basicity of a substance such as water, it would be important to keep the pH of hot-tub water between 7 and 7.6 because if the acidity is too high, the walls of the hot-tub may be damaged, and if the pH is too low, the heating thing may get damaged.

Which is the first step that geologists must do to compare rock layers at distant locations?
find the absolute age of rocks at both locations
compare a layer at one location to layers at other locations
identify index fossils in one or more layers at one location
collect fossils from different locations to study the organisms’ lifestyles
Answer: Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.
Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.

Answer:
D. All of the above
Explanation:
Molecules, ions, and pure elements might be included in a chemical reaction. Therefore, option (d) is correct.
What is a chemical reaction?A chemical reaction can be described as a reaction that brings the chemical conversion of one chemical substance to another chemical substance. The reactions cause chemical changes that include the rearrangement of electrons in order to create and break bonds between atoms.
The compound or molecules which are primarily utilized in a reaction are called reactants. Chemical reactions give products, which possess characteristics different from the reactants of the reaction.
Chemical reactions take place at a definite rate of reaction at a given concentration, temperature, and pressure. The rate of reaction increases with the rising temperature of the reaction as more activation energy is available for reactant molcules collisions.
Therefore, in a chemical reaction reactants and products can be present as Molecules, ions, and pure elements.
