Answer:

The rate at which an enzyme catalyses a particular reaction is calculated by the amount of substrate being used up. The concept of a chemical reaction is that the substrate is converted into product with the help of an enzyme.

Rate of reaction= Amount of substrate utilized or product formed/ Time taken

Explanation:

Temperature is an important factor in the deciding of a rate of reaction. The velocity of an enzyme <u>increases with an increase in temperature</u> until and optimum temperature is achieved. After that, the velocity of an enzyme starts <em>decreasing</em> since the enzyme starts to get denatured.

Enzymes work best at a <em>specific pH</em>. If there are changes in pH, the active site of an enzyme gets modified and the rate of reaction decreases. Certain enzymes like pepsin which is in our stomach works at an acidic pH of 2.0.

Answer:

1. It serves as the functional unit of the nervous system. <em>b. neurons</em>

2. It collects information from the sense organ such as the eyes and the nose. <em>c. peripheral nervous  system</em>

3. It serves as the primary organ of the  central nervous system. f. spinal cord​  

4. It controls or regulates the body's internal brain environment, including the body temperature,  pulse and respiration rate, and bood pressure. <em>e. autonomic nervous  system</em>

5. It is one of the systems that is directly involved in maintaining the normal functions of cells. <em>d. nervous system</em>  

Explanation:

Neuron: Neurons are the structural and functional units in the nervous system.  Neurons transmit nervous impulses. These cells are formed in general by a cellular body, dendrites that are cytoplasmic extensions that receive stimuli from other cells, and an axon that is a long formation capable of conducting the electrochemical signals. Every neuron forms connections with other neurons. These connections are known as synapsis.

Peripheral nervous  system: Sense information is received by the peripheral nervous system and processed by neurons and synapses in the central nervous system. There are three types of neurons involved in this transmission: sensory or efferent neurons, interneurons, and motor or efferent neurons.

Spinal cord: The nervous system might be divided into the central nervous system and peripheral nervous system. There are two organs involved in the central nervous system that funtion as control centers. One of them is the brain, and the other organ is the spinal cord, surrounded by the vertebral column.  

Autonomic nervous  system: The autonomic nervous system is conformed by the sympathetic nervous system and the parasympathetic nervous system. It has too many functions in the organisms, controlling pressure, heart bitting, body temperature, sexual responses, urination, digestion, general metabolism, among others. It controls and regulates the whole organism.  

The nervous system: Homeostasis refers to stability, balance, or equilibrium. The organism needs to maintain homeostasis to guarantee the correct functioning of cells, tissues, organs, and so on. The homeostatic regulation is controlled by the endocrine system and by the nervous system, which acts as the control center.

What is the role of RNA polymerase?
juin [17]
<span> RNA polymerase is commonly know as DNA-dependent RNA polymerase. It catalyzes the transcription of DNA to synthesize precursors of mRNA and most snRNA and microRNA. It is found in the core of eukaryotic cells. One of which combined rRNA in the nucleolus while the rest of the chemical blends other RNA in the nucleoplasm, some portion of the core yet outside the nucleolus.</span>

Construct an argument about how the physical and biological components in the Chesapeake Bay ecosystem affect the crab populatio
Tamiku [17]

To make an argument about how environmental imbalance affects the ecosystem of the Chesapeake Bay, research on reliable sources on the topic is necessary.

<h3 /><h3>How is the Chesapeake Bay?</h3>

The bay corresponds to the largest ecosystem of estuaries in the USA, being a source of diverse types of habitat for wildlife, with more than 3,600 species of animals and plants.

An example of the environmental imbalance in the area is the commercial and recreational fishing of blue crab, whose population had a significant reduction in 2022.

Therefore, environmental factors and human exploration are responsible for generating such an imbalance, and the development of policies and actions to promote sustainability is essential.
