Echinoderms, like sea stars, have a nervous system like nerve net. The correct answer is option C.
The nervous system is a complex network of specialized cells called neurons that transmit signals between different parts of the body. It is responsible for coordinating and controlling all of the body's functions, including movement, sensation, thought, and emotion.
Therefore, the correct answer is option C. Nerve net.

The given question is incomplete. The complete question is:
Echinoderms, like sea stars, have a nervous system.
A) Ring- like
B) ladder- like
C) Nerve net
B hydrogen
C oxygen
D nitrogen
The correct answer is option B, hydrogen.
The majority of the atmospheric gases are found in the sea water solution. In supplementation to oxygen and nitrogen, the most profusely found gas in the atmosphere, that is, carbon dioxide is found in the ample concentrations in the ocean waters.
However, hydrogen is not present, and if found it is found in minute concentration. Of the gases, nitrogen is the most abundant gas found in seawater, while oxygen is the second most abundant, and carbon dioxide is the most soluble gas, and one of the various constituents, which influences the pH balance of the ocean.
The answer is B. hydrogen.
b. light.
c. matter.
d. heavy.
Answer:
The correct answer in this case is the first option archaea.
Explanation:
Hello!
Let's solve this!
Within the domains, that of Bacteria and that of Arqueas are very similar, since both group prokaryotic unicellular organisms. One of the differences is that one of the domains has organisms with a cell wall with peptidoglycan and the other domain does not.
The domain, and the correct answer in this case is the first option archaea
Archaea, also known as archaebacteria, are unicellular prokaryotes that do not contain peptidoglycan in their cell walls. They differ from Eubacteria, which do contain peptidoglycan. Eukarya, on the other hand, contains all eukaryotic cells.
The domain that is composed of unicellular prokaryotes that have cell walls that do not contain peptidoglycan is
Archaea (or archaebacteria). Unlike Eubacteria, the other major group of prokaryotes, the cell walls of Archaea do not contain peptidoglycan. Each of these domains, Archaea, Eubacteria, and Eukarya, represent a major category of life. It's worth noting that Eukarya contains all organisms with eukaryotic cells, including humans, animals, plants, and fungi.
Archaebacteria are known for surviving in extreme environments, such as hot springs or salt lakes.

Answer:
Explanation:
When enzyme is denatured due to high temperature the reaction slows down because enzymes are catalyst that speeds up rate of reaction hence , the gibbs free energy which is energy at work reduces due a decrease in enzymatic reaction that affects the overall reaction.
ΔG = ΔH - TΔS
Gibbs free energy is the energy at work i.e the energy that use to do work
Gibbs free energy equation determines if a chemical equation is spontaneous or not. If ΔG is negative, it is spontaneous, if it is positive, it is not spontaneous.
Enthalpy is the
sum of internal heat with pressure and the volume of the system
Internal heat+pressure+ volume
ΔH is change in enthalpy, or energy in a system, and
Entropy is the rate of disorderliness of a system, when a system is highly disordered the entropy is high TΔS is difference in entropy multiplied by temperature, and entropy is the energy that is not used for work and accumulates as waste heat. So if difference in enthalpy is greater than difference in entropy multiply by temperature it means energy was added to the system.
The Gibbs Free Energy Equation represents how different components drive a reaction, including change in free energy, enthalpy, temperature, and entropy. When the temperature is increased in a system, enzymes can denature due to increased entropy, leading to a greater possibility for spontaneous reactions.
In the Gibbs Free Energy Equation: ΔG = ΔH – TΔS, ΔG represents the change in Gibbs free energy, which is the amount of energy available to do work in a system. ΔH stands for the change in enthalpy, or the total energy of the system. T is the temperature of the system (in Kelvin), and ΔS is the change in entropy, or disorder in the system. When you increase the temperature in a system, enzymes become denatured because the added heat disrupts the bonds that hold the enzyme's shape. This increase in entropy, represented by ΔS in the equation, contributes to an increased possibility for spontaneous reactions (negative ΔG). As a result, by increasing the temperature, more energy is necessary to maintain a highly ordered system, otherwise reactions may happen spontaneously and create chaos within the system.
