9. Scientists are studying cellular respiration in a jungle ecosystem that has plants,
animals, and decomposers (which consume dead things). Which group or groups of
organisms in the jungle carry out cellular respiration?
plants
animals and decomposers
all organisms in the jungle
animals.
Answer:
all organisms in the jungle
Explanation:
Scientists are studying cellular respiration in a jungle ecosystem that has plants, animals and decomposers, so all organisms in the jungle carry out cellular respiration.
What is cellular respiration?Cellular respiration is a process in which organism use the oxygen molecule for the conversion of their food materials to get the chemical energy by the product of water and carbon dioxide.
This respiration process is done by all living organism like plants, animals, insects, bacteria, etc. to get energy for the other cellular functions. So, in the ecosystem of jungle plants, animals and decomposers all will perform cellular respiration.
Hence, option (c) is correct i.e. all organisms in the jungle.

Explanation:
during a heating or cooling process, how are changes in enthalpy and temperature related?
The answers are in the picture. this us the question, An increase in carbon dioxide production has led to an increase in global temperatures, which is causing glaciers to melt faster. If this trend continues, how will animals living in the polar regions be affected?
Answer:
D
Explanation:
because if there is no land for them they wont survive in only water
The increase in global temperature melts the ice in polar regions. This worsely affects the animals living there. Hence, they will migrate to other areas but this is in fact not possible for their adaptation in other areas and they may subject to extinction.
What is global warming ?Global warming is the rise of temperature of earth surface all over the world. The significant reason for global warming is green house effect. Gases like carbon dioxide, methane gas etc. are intensely absorbing temperature that is radiating back from earth.
Hence, these gases are increasing the atmospheric temperature in earth. Global warming have very serious impacts that going up to the major discussion to solve nowadays.
The melting of polar icebergs and rising of sea level definitely leads to the extinction of animals living in polar region. They cant be adopted to other regions and migrating to other areas does not save them. Hence, they will extinct from earth. Therefore, option d is correct.

How does energy play a role in different rock types forming? I had this question another time in my test and it's asking the same thing again.
Answer:
Yes
Explanation:
Yes, there are many energy forces that directly affect the formation of rocks and other substances. The Sun itself provides both energies in the form of heat/radiation and magnetic energy. Heat can get so intense when combined with pressure from being so far underground that it causes rocks to melt and become magma, which combines with other minerals and forms new types of rocks when they cool in the future. Magnetic energy helps push and pull the waves and wind on Earth which ultimately break down rocks into sand over the years.

b) Why is aluminium extracted using electrolysis and not carbon?
Answer:
Aluminum is more reactive than carbon so it must be extracted from its compounds using electrolysis.
Explanation:
Even though aluminum is more abundant than iron in the Earth's crust, aluminum is more expensive than iron. This is mainly because of the large amounts of electrical energy used in the extraction process.

What characterizes a system at equilibrium?
O A. The system is changing at an even rate.
B. The system has stopped changing.
O C. The system cannot undergo change.
D. There is no net change to the system.
Answer:
D. There is no net change to the system
Explanation:
Equilibrium means "equal". In a chemical system, changes occur in substances called the reactants to produce another substance called the products. These changes from reactants to products and vice versa occur at an uneven rate until EQUILIBRIUM is reached.
In other words, equilibrium is attained when the reactants and products are formed at an equal or constant rate i.e. There is no net change to the system. For example, in the chemical system below:
A + B ⇌ C + D
This system is said to be at "EQUILIBRIUM" if the rate of reaction of the reactants (A and B) is equal to that of the products (C and D). That is, there is no net change (difference) in the reaction rate.

How many moles are there in 17.6g NaOH?
Answer:
The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide.
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 0.44moles are there in 17.6g NaOH.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. The stoichiometry represents the number of moles.
Mathematically,
number of moles of NaOH =given mass of NaOH÷ molar mass of NaOH
Molar mass of 1 mole of NaOH= 40 g/mol
mass of NaOH= 17.6g
Substituting all the given values in the above equation, we get
number of moles of NaOH = 17.6g ÷ 40 g/mol
number of moles of NaOH =0.44moles
Therefore, 0.44moles are there in 17.6g NaOH.

Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter, causing the metal to stiffen and fracture. This is known as metal fatige. The bending causes that to occur.
What is metal ?A metal is a substance that has a shiny look when freshly processed, polished, or shattered, and conducts electricity and heat rather effectively. Generally speaking, metals are malleable and ductile.
These characteristics are the outcome of the metallic link that exists between the metal's atoms or molecules.
The earth's crust is where most pure metals are found. They are discovered in ores, which are solid materials from which metals and minerals may be extracted. The majority of the planet's iron mass, which makes up over a third of its mass, is located in its core.
Thus, Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter.
