Answer is: (1) a different molecular structure and different properties.
Different forms of the same element that have different properties because of different atom arrangements are called allotropes.
Carbon has many allotropes, but two most important are graphite and diamomd.
Graphite has sp2 and diamond has sp3 hybridization of carbon atoms, because of that graphite conduct electricity and diamond not.
In diamond carbon atoms are arranged in the face centered cubic crystal structure called a diamond lattice.
Diamond has very strong covalent bonds between carbon atoms and because of that it has the highest hardness and thermal conductivity of any bulk substance.
please help
thank you so much!
Answer:
The correct answer will be- by providing different amount of water to experimental groups.
Explanation:
The scientific experimental samples are divided into two groups: the control group in which the variable to be studied is kept constant and the experimental variable to which different amount of studied variable is provided.
In the given question, the scientific question is how much amount of water is required for the optimal growth of the plants. The variable to be studied is water, so different amount of water is provided to different pots like 10 ml, 20 ml, 30 ml and so on. So the plant which will respond best to this amount will be the optimal concentration of the water required by the plant to grow.
Answer:
If some would ask me to determine the purity of an unknown powder that contains illegal drugs like cocaine, they would probably be wanting to remove other substances that are added like baking soda, and the reason this is so important is that sometimes the ingredients they get to mix with have an effect on the test and may miss lid the results.
Explanation:
a. the sun, moon at perigee, and Earth forming a triangle
b. the sun, moon at apogee, and Earth forming a triangle
c. the new moon at apogee coming between Earth and the sun along a straight line
d. the new moon at perigee coming between Earth and the sun along a straight line
Answer:
d. the new moon at perigee coming between Earth and the sun along a straight line
Explanation:
Solar eclipse occurs when moon comes in between sun and Earth and the three align in a straight line. The moon blocks the sunlight falling on the earth. The earth passes through the shadow of the moon.This phase of moon is New moon.
A total eclipse is said to occur when the disc of moon complete covers the disc of sun. This happens when moon is at closest position to earth in it orbit that is at perigee.
The substrate, enzyme pair from the citric acid cycle that is INCORRECT is E) Citrate, aconitase.
The citric acid cycle, also known as the Krebs cycle, is a crucial metabolic pathway for generating energy in cells. Each step involves specific substrates and enzymes. While all other options (A, B, C, and D) correctly match substrates and enzymes involved in the cycle, option E (Citrate, aconitase) is incorrect.
Aconitase is responsible for catalyzing the interconversion of citrate and isocitrate, not for the conversion of citrate itself. The correct pair for citrate is citrate synthase, which catalyzes the formation of citrate from oxaloacetate and acetyl-CoA.
Understanding these substrate-enzyme pairs is essential in comprehending the citric acid cycle's intricacies. Accurate knowledge of these reactions aids in grasping how cells produce energy through this pathway. This emphasizes the significance of precise knowledge of biochemical pathways for an accurate understanding of cellular processes.
In the context of cellular metabolism, identifying the correct enzyme for each substrate is vital for accurate biochemical analysis and the design of targeted interventions for metabolic disorders. Among the given options, the substrate, enzyme pair that is incorrect in the citric acid cycle is Citrate, aconitase.
To Know more about Enzyme, refer;
The incorrect substrate-enzyme pair from the citric acid cycle is Oxaloacetate, citrate synthase.
The citric acid cycle, also known as the Krebs cycle or tricarboxylic acid cycle, is a series of chemical reactions that occur in the mitochondria of cells. It plays a crucial role in the aerobic respiration process, generating energy-rich molecules such as ATP.
The citric acid cycle involves the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. Each step of the cycle is catalyzed by a specific enzyme, which acts on a particular substrate.
The correct substrate-enzyme pairs in the citric acid cycle are as follows:
Therefore, the incorrect substrate-enzyme pair from the given options is D) Oxaloacetate, citrate synthase.
