1. At the freezing point, the particles in an object have no kinetic
energy.
2. On the Celsius temperature scale, there are no negative
numbers.
3. The more particles an object has at a given temperature, the
more thermal energy it has.
4. Object A is much larger than Object B, but both are made of
the same material. If both objects are at the same temperature, the thermal energy
of Object A is the same as the thermal energy of Object B.
5. When heat is absorbed by an object, the speed of the particles
in the object is unchanged.
Answer:
true
Explanation:
False. At the freezing point, the particles in an object have some kinetic energy.
False. On the Celsius temperature scale, there are negative numbers.
True. The more particles an object has at a given temperature, the more thermal energy it has.
False. Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
False. When heat is absorbed by an object, the speed of the particles in the object is changed.
Explanation:
The temperature is defined as the measure of hotness and coldness.It is measured in terms of degrees Celsius, Kelvins, degrees Fahrenheit.There are negative numbers on the Celsius temperature scale and Fahrenheits temperature scale but not on the Kelvin temperature scale.It is a measure of the average kinetic energy of the particles of the object.The hotter the object, the higher will be the kinetic energy of the particles of the object, higher will be the value of temperature. The colder the object, the lower will be the kinetic energy of the particles of the object, lower will be the value of temperature.The object with more mass will have more particles and more will be the kinetic energy associated with the particles.When heat is added to an object to raise its temperature the kinetic energy of the particles increases. As kinetic energy is directly linked with speed or velocity.So from this, we can conclude that :
At the freezing point, the particles in an object have some kinetic energy.
On the Celsius temperature scale, there are negative numbers.
The more particles an object has at a given temperature, the more thermal energy it has.
Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
When heat is absorbed by an object, the speed of the particles in the object is changed.

Gene expression is influenced by many factors. Which of the following is a factor in gene
expression?
Answer:
Answer: The Environment.
Environmental factors, such as diet, medicines, or exposure to toxins, can change how genes are expressed.
What are factors affecting gene expression?Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.
Expressivity can be impacted by a number of elements, such as genetic make-up, exposure to dangerous substances, other environmental effects, and age. Penetrance and expressivity both have a range: People who carry the gene may or may not exhibit the trait, and when they do, the trait's expression can take many different forms.

Oligomycin stops ATP Synthase. Predict what will happen to the concentration of pyruvate, NADH and H+ when ATP synthase is stopped by oligomycin.
Answer:
Pyruvate - No change
NADH- No change
Intermembrane H+ Concentration- Increase
Explanation:
The concentration of both pyruvate and NADH does NOT CHANGE by Oligomycin, whereas the concentration of protons (H+) INCREASES.
Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.
Pyruvate is generated by glycolysis in the cytoplasm. This process (glycolysis) generates two molecules of pyruvate for each molecule of glucose.
Moreover, the reduced form of Nicotinamide adenine diphosphate (NADH), is produced during glycolysis and the Krebs cycle.
During oxidative phosphorylation, NADH is consumed in the electron transport chain.
NADH is used to create an electrochemical gradient by pumping protons (H+) across from the mitochondrial matrix to the inter-membrane space.
Subsequently, this electrochemical proton gradient is then used to produce ATP by an ATP synthase.
In conclusion, the concentration of both pyruvate and NADH does NOT CHANGE by Oligomycin, whereas the concentration of protons (H+) INCREASES.

Light energy from the Sun is used by a plant to perform
photosynthesis. Which structure of the plant helps it to absorb this
energy?
Answer:
Chlorophyll absorbs the energy from the sun.
Explanation:
Light absorbed by chlorophyll excites the electrons in the ring as shown below.
Answer:
chlorophyll
Explanation:
The main pigment used in photosynthesis, chlorophyll, reflects green light and most intensely absorbs red and blue light. In plants, chloroplasts containing chlorophyll are subject to photosynthesis.
A double membrane wraps chloroplasts and includes a third inner membrane, the thylakoid membrane, which forms long folds within the organelle.

Answer:
Hilly towards flat.
Higher elevation toward lower elevation.
Clayey to sandy type of soil.
Explanation:
The land of Charlotte NC is hilly whereas coastal plains of North Carolina is flat. Charlotte NC is located at a high elevation while on the other hand, the coastal plains of North Carolina are located at the sea and at lower height. The soil type of Charlotte NC is clay and silt whereas the soil type of coastal plains of North Carolina is sandy due to the presence of sea.

In the 1940s, American farmers lost 7% of their crops to pests. By the 1990s crop losses due to pests had risen to 13%. Select a reason for this increase.
A. Between the 1940s and 1990s more land was being developed for houses and city space. Less land was used to grow crops. The increased number of crops in smaller spaces led to increased numbers of pests.
B. The farmers were using reasonably effective pesticides in the 1940s. However, over time, more pests have evolved to become more resistant to the pesticides.
C. The pesticides decreased in quality due to America's expanding economy, allowing more pests to successfully feed on the crops.

1. What two reactants enter the mitochondrion?
2. Compare the reactions in mitochondria with glycolysis.
1. How does a cell obtain energy?
2. Under what conditions does fermentation occur in a cell?
3. If a cell could perform both cellular respiration and fermentation, which process would benefit the cell more?
Answer:
1.NADPH2 and FADH2 , and O2
Explanation:
NADPH2 and FADH2 get oxidized in the electro transport chain into NADP+ and FAD+ and water and oxygen and yield 3 ATP molecules and 2 ATP molecules per each molecule respectively
Following are the answers:
The two reactants that enter the mitochondrion are pyruvate, the end product of glycolysis, and oxygen.In the mitochondria, pyruvate and oxygen undergo a series of reactions called cellular respiration, which produces energy in the form of ATP. This process is more efficient than glycolysis, which only produces a small amount of ATP.A cell obtains energy through a variety of processes, including cellular respiration and fermentation.Fermentation occurs in a cell when there is a lack of oxygen, such as in anaerobic conditions.In general, cellular respiration is more efficient than fermentation in producing ATP, but fermentation is a useful process for cells to produce ATP when oxygen is not available.What is mitochondria?Mitochondria are organelles found in the cells of most eukaryotic organisms, including plants, animals, and fungi. They are often referred to as the "powerhouses" of the cell because they are responsible for producing the majority of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy.
Mitochondria are membrane-bound structures that contain their own genetic material, separate from the cell's nucleus, and are responsible for their own replication. They have unique characteristics that allow them to produce energy through the process of cellular respiration, a series of reactions that convert the energy from food molecules, such as glucose, into ATP. This process is one of the most important biological processes in living organisms, as it allows cells to perform their functions and sustain life.
