What’s the difference in concentration of hydronium Ions between pH1 and pH4?
a) x 2.6
b) x 1000
c) x 4
d) x 10
Answer:
The difference in concentration of hydronium Ions between pH1 and pH4 is 1000 times.
The difference in concentration of hydronium Ions between pH1 and pH4 is - Option b) x 1000.
pH scale is a scale or measure to find the strength of acidity or basic nature of a solution or substance. pH 1 is acidic and pH 14 is most basic on scale.
Acids combine with water molecules to form hydronium ion, H3O+. Therefore, pH formula in aqueous solution becomes-
pH = - log [H3O+].
taking antilog on both the sides, the concentration would be calculated as
[H3O+] = antilog (- pH)
In the first case, pH given is 1. So,
=> [H3O+] = antilog (- 1)
= 0.1
In the second case, pH given is 4. So,
=> [H3O+] = antilog (- 4)
= 0.0001
Thus, the concentration of hydronium ion at pH 1 is around 1000 times greater than that of concentration at pH 4.

What are plate tectonics ?The tectonic plates of different parts of the earth's crust are always in motion, causing changes in the planet's landforms .
However the globe would look same due to presence of plate tectonics with a stable climate, mineral and oil deposits, and oceans with a chemical balance.
These plates are mainly 100 km thick, are made up of this crustal layer which continue to float on the warm and thick mantle, and create mountains
These plates are puzzle like matching pieces on the surface of the planet that , the movement of the plates caused by the mantle convection from below the lithosphere.

Aristotle's ladder of nature, and the Great Chain of Being, were concepts suggesting __________.
a) life evolved on other worlds and was later transported to Earth down a celestial ladder
b) the accurate evolutionary view that all species are related, with each providing an evolutionary link (i.e. step in the ladder) to its immediate ancestor
c) the mystical teleological view that all species were created in a fixed order, from least to most perfect
d) life is a painful and purposeless experience of endless steps, but death brings release from the ladder of life
Answer:
The most correct option is C
Explanation:
Aristotle ladder of nature can be described as an idea (referred to as Scala Naturae) to organize all things (living and non-living) into a "ladder" where organism fits into a "step" on the ladder. He ranked animals higher than plants and plants higher than non-living things (like minerals). Humans were ranked first in his ladder.
The Great chain of Being is also a form of hierarchial ranking (of old christianity) starting from God to angels to humans to animals to plants and then finally to minerals.
These rankings have been suggested in the past by some "radicalists" to mean that all species were created from the simplest to the most complex and perfect which can be loosely translated to mean that all species were created in a fixed order, from least to most perfect
Which statement best describes how a diagram of photosynthesis would differ for a diagram of cellular respiration?
A. The photosynthesis diagram would show UV rays as the final product
B. The photosynthesis diagram would show water as the main source of chemical
energy
C. The photosynthesis diagram would show glucose as the main source of energy
D. The photosynthesis diagram would show radiant (solar) energy as the main
source of energy
Answer:D
Explanation:
Photosynthesis main energy source is solar energy while cellular respiration uses chemical energy
The main source of energy in the process of photosynthesis in plants is radiant (solar) energy. Plants convert this solar energy into chemical energy in the form of sugars (food). Thus, the correct option is D.
What is Photosynthesis?Photosynthesis is the phenomena by which plants prepare their food. Photosynthesis takes place in the chloroplast of green leaves. The chloroplast contains chlorophyll. Chlorophyll is the pigment responsible for photosynthesis. Chlorophyll traps the solar energy (light) in the cells which is then converted into chemical energy. The chemical energy is in the form of sugars (glucose).
In cellular respiration, the chemical energy in the form of glucose is converted into ATP (energy currency of the cell).
Therefore, the correct option is D.

When cells are damaged, new cells are created by cell a process called cell division. The cell theory supports this fact as it states that all cells have a nucleus that divides.
What is the cell theory?All living things are primarily composed of cells, which serve as both the basic structural and organizational units of all living things. According to the biological notion known as "cell theory," all cells are descended from previously existing cells. All living things are composed mostly of cells, which also serve as the fundamental unit of reproduction. The cell theory is based on the following three basic postulates: Every living thing is made up of one or more cells.The fundamental unit of structure and organization in organisms is the cell. New cells are created from pre-existing cells. Theodor Schwann and Matthias Jakob Schleiden are two scientists usually credited with developing or discovering the cell theory. In 1839, Schleiden claimed that every structural element of a plant is composed of cells or is a cell-derived substance. Additionally, he suggested that cells were created through a crystallization process that took place either inside or outside of other cells.

While visiting Wave Rock in Australia, you observe streaks of minerals present on the landform. What natural process most likely caused the streaking?
The answer is deposition
Answer:
Deposition would have most likely caused the streaking.
Explanation:
Deposition is the laying down of sediment carried by wind, water, or ice. Sediment can be transported as pebbles, sand & mud, or as salts dissolved in water. Salts may later be deposited by organic activity or by evaporation.
One example of deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid. This causes the water vapor to change directly into a solid. Another example is the soot that is deposited on the walls of chimneys.
