Answer:
• An acid is an electrolyte that hydrolyses in water to release hydrogen ions.
• pH level of an acid;
- Strong acid → 0 - 3.8
- Weak Acid → 4.0 - 6.7
A scientific law describes an observed pattern found in nature without explaining it. The theory is the explanation.
Answer:
atoms (2), community (11) , biome (13), biosphere (14), cells (5), organism (9), ecosystem (12), molecules (3), organ (7), organelles(4), organ system (8) , population (10), subatomic particles(1), and tissues (6)
Explanation:
Levels of organization in order from the simplest to the most complex are:
- Subatomic particles-neutrons, protons and electrons that make up the atom.
- atoms- Smallest particle of a substance that may or may not exist freely.
- molecules- two atoms combine to form molecule. e.g H₂
- organelles- organelles are functioning structures of a cell. e.g. Golgi apparatus.
- cells- organelles combine to form cell. e.g. Parenchyma cells.
- tissue- cells of similar origin and function form the tissue e.g. Cardiac tissue
- organ- tissues combine together to form organs. e.g. Heart
- organ system- many organs combine together to form system. e.g Circulatory system
- organism- several organ system combine to form an organism. e.g. Human being.
- population-organism of same species form a population.
- community- different population combine to form a community.
- ecosystem- communities live in a particular area and interact with the abiotic as well as biotic factors of that area to form ecosystem. e.g. pond ecosystem
- biome-A geographical area where several ecosystem sharing same abiotic factors thrive.e.g. tiaga biome
- biosphere- Narrow zone of the earth where the atmosphere , hydrosphere and lithosphere meet to support life.
Answer:
Explanation:
From the given information:
It is pertinent to understand that few things need to be considered in this process. The huge metallic vessel needs warming alongside legitimate guidelines of temperature for powerful heat need of the container(organism) in the first place. Simultaneously it is additionally appropriate to chill off the substance of the vessel and justified the cooling limit. Kindly note that it is temperature is additionally related to the encompassing pressing factor and diminished temperature is a characteristic of lower pressure, which can be considered surrounding pressure (one or lower than 1 air pressure).
SO;
Specific gravity = 1
mass of water = 135 kg which is equivalent to 135 liters
To ; we have:
1 liter = 100
5 liter = 292
∴
135 L will yield 2631.616
However, converting this into MegaJoules
Recall that:
cal/ = 1 calorie or 4.19 Joules
4.19 Joules = 4.19 × 10⁻⁶ MegaJoules
Hence;
2631.616 = (2631.616 × 4.19 × 10⁻⁶) Mega Joules
= 0.0110264878
= 11026.47 × 10⁻⁶ Mega Joules per day
Answer:
as I know
Explanation:
<em>Igneous rocks, which form from cooling magma or lava, and metamorphic rocks, which have been altered by heat and pressure, are unlikely to contain fossils. The “soft” tissues of an organism, such as skin, muscles, and internal organs are typically not preserved as fossils.</em>
