Answer:
It is an example of enzyme activation through the pH of the environment surrounding the enzyme.
This phenomenon is called proenzyme, proenzymes are inactive enzymes that, due to chemical changes in the environment that vary, are activated or not depending on these.
Explanation:
Proenzymes, generally the best known or named, are found in the digestive system, where the sequential digestion of food is essential, with an order, and the enzymes must be controlled or activated at certain moments of digestion.
Proenzymes can be activated by the presence of chemicals, pH acids and even pH alkalinity, the change of the medium is what gives the enzyme permission to start with its reaction effect.
Usually this happens with enzymes that must be controlled, and that their activity must be in certain periods so as not to generate pathologies or even destroy a tissue of the organism.
Answer:
This question includes the following options to choose from:
A) 2 B) 12 C) 8 D) 9 E) 10
3 point testcrosses focus on analyzing the inheritance blueprints of alleles by crossing triple heterozygotes with triple recessive homozygotes, allowing therefore to find out the distance between the alleles, and also their location order on the chromosome.
And it all comes down to the frequency of recombination, in this case such frequency between C&A is 0.02, in the same fashion that it's 0.08 between A&B; thereby the answer is A). 2
B. through fixation of carbon in the soil
C. when carbon transpires from their stomatae
D. when they are eaten by animals.
Answer:
the answer is D
Explanation:
Because when they are eaten their left over air goes into the other animals.
Cold-blooded animals change their body temperature to match the environment.
Mammals and birds are usually cold blooded.
All of the above.
Answer:
Explanation:
Cold blooded animal did not have cold blood.
Cold blooded animals can’t change their body temperature to match the environment.
Mammals and birds are not cold blooded.
Endotherms, such as mammals and birds, are able to maintain a constant body temperature in the face of changing environmental conditions. In contrast, cold-blooded animals, or ectotherms, have a body temperature that matches their environment and varies with it.
An animal that maintains a constant body temperature in the face of environmental changes is called an endotherm. These animals are able to maintain a level of activity that an ectothermic animal cannot because they generate internal heat that keeps their cellular processes operating optimally even when the environment is cold.
Mammals and birds evolved endothermy, meaning they regulate their body temperature from the inside through metabolic or physical changes. This allows them to maintain a relatively stable body temperature regardless of the outside temperature.
Cold-blooded animals, also known as ectotherms, rely on external temperatures to set their body temperature. Their body temperature varies with the environment.
(b) Electrical-->Chemical-->Chemical
(c) Chemical-->Electrical-->Chemical
(d) Electrical-->Chemical-->Electrical
Answer:
(d) Electrical-->Chemical-->Electrical
Explanation:
A nerve impulse is the transmission of an electrical change along the neuron's membrane from the point at which it is stimulated (synapse). The normal direction of impulse in the body is from the cell body to the axon. This nerve impulse, or action potential, is a sudden and rapid change in the transmembrane potential difference.
Normally, the membrane of the neuron is polarized at rest, which means that the ionic constitution of the medium internal to the membrane is different from the external medium, which generates different electrical charges in one medium and the other, so this difference, ie , the potential during rest is negative (-70 mV). The action potential thus consists of a rapid reduction of membrane negativity to 0mV and inversion of this potential to about + 30mV, followed by a rapid return to values slightly more negative than the resting potential of -70mV.
Nervous impulse or action potential, therefore, is a phenomenon of an electrochemical nature and occurs due to changes in the permeability of the neuron membrane. These permeability modifications allow ions to pass across the membrane. Since ions are electrically charged particles, changes also occur in the electric field generated by these charges.
Thus, we can say that the correct answer to this question is: Electrical -> Chemistry -> Electrical
