Reactant energy
Endothermic energy
Activation energy
Exothermic energy
Answers
Activation energy is the amount of energy that must be supplied to get a chemical reaction started.
What is Activation energy?The activation energy is the first and minimum amount of energy input that is used in the reaction to start it and later returned.It is denoted by [tex]E_{A}[/tex].
[tex]E_{A}[/tex] always has a positive value – independent of whether the reaction is endergonic or exergonic overall.
The primary source of activation energy is heat, which reactant molecules absorb from their environment. This heat energy jolts the atoms and bonds within the individual molecules, raising the likelihood that bonds will break, and speeds up the velocity of the reactant molecules, increasing the frequency and force of their encounters.

12. The temperature scale that is typically not used for scientific measurements is option c. Centigrade.
Fahrenheit, Celsius, and Kelvin are the three scales that are most frequently used to measure temperature.Because all molecular activity stops at its zero points, Kelvin is known as the absolute scale.13. Between freezing and boiling on the Celsius scale, there are (100 - 0) = 100 degrees.
14. The given statement about the developer of the Celsius scale is True. It was developed by Anders Celsius.
15. True, at 0 K, there is absolutely no molecular motion. This is known as absolute zero.
16. Kinetic energy
An object's kinetic energy is the power it has as a result of motion. It is explained as the amount of effort required to move a mass-based body from rest to the indicated velocity. The body keeps its kinetic energy, which it acquired during acceleration unless its speed changes.

A. Do germinating peas release oxygen in the process of respiration?
B. Do germinating peas release water in the process of photosynthesis?
C. Do germinating peas absorb water in the process of photosynthesis?
D. Do germinating peas release carbon dioxide in the process of respiration?
Answers
The increase in water level shows that respiration in the conical flask is causing gram seeds to germinate, which releases carbon dioxide. Thus, option D is correct.
What gases are released by germinating peas?The KOH solution in the little test tube absorbs the CO2 that the germination of the seeds in the conical flask releases during breathing.
As a result, a small vacuum is created inside the flask, forcing the water up the delivery tube. It demonstrates that seeds that are germination carbon dioxide during respiration.
By mixing glucose with oxygen from the air, organisms create energy during the process of respiration. Glucose and oxygen are converted into energy and carbon dioxide during cellular respiration.
During the process of cellular respiration, carbon dioxide is released into the atmosphere.
Therefore, germinating peas release carbon dioxide in the process of respiration.

B. The frequency of dominant alleles in the population (p)
C. The percentage of individuals in the population that are heterozygous:
D. Provide an explanation for why so many fish in the lack display the recessive
trait
Answers
The predominant allelic frequency is the allelic frequency of the recessive gene, the genotypic frequency of homozygous dominants (p2), genotypic frequency of homozygous recessives (q2), 2pq the genotypic frequency of heterozygotes
These allelic frequencies add up to 1, so p + q = 1. Likewise, the genotypic frequencies add up to 1, so p2 + 2pq + q2 = 1.
q² = 600/680 = 0.882
We can determine the recessive allele if q2 represents the homozygous recessive genotypic frequency. by removing the equation, frequency
q= √0.882 = 0.939
We will receive both homozygous and heterozygous phenotypic frequencies.
p+ q =1
p=0.061
Knowing that 2pq is the heterozygous genotypic frequency, we can quickly compute it by substituting the following terms for:
2pq=2 x 0.061 x 0.939 = 0.115.
Directional selection increases the percentage of people who have one of severe phenotypic characteristics This trait makes people more likely to survive in particular circumstances. Additionally, genetic drift might be in play. Allelic frequencies in a population shift over many generations due to genetic drift, an evolutionary mechanism.

Resistance refers to the ability of a population to tolerate the disturbance while on the other hand, the resilience refers to the ability to recover a population after suffering from the disturbance. Stability of an ecosystem is defined as to the capability of a natural system to do self-regulating mechanisms in order to return to a steady state after disturbance occurrence of disturbance.
