Answer:
D. activation energy
Explanation:
A catalyst lowers the activation energy of a reaction. Activation energy is the initial amount of energy needed to set a reaction into motion. Catalysts, including enzymes, can lower the activation energy to speed up reactions and make them easier to initiate.

true or false
Answer:
FALSE
Explanation:
The CNS only controls the brain and spinal cord
PLEASE mark BRANLIEST :)
The Central Nervous System (CNS) contains all of the nerves outside of the brain and spine, which is false, as the Central Nervous System (CNS) actually consists of the brain and the spinal cord.
What is the central nervous system?
The central nervous system consists of the brain and the spinal cord, which are protected by the skull and vertebral column, the brain is the body's control center and is responsible for processing and coordinating information from the senses, controlling movements and actions, etc, and the spinal cord is a long, thin bundle of nerves that is responsible for transmitting signals between the brain and the rest of the body.
Hence, the Central Nervous System (CNS) contains all of the nerves outside of the brain and spine, which is false.

Explain how the data from your experiments showed that cyanide was used to poison Jared, and that 2-deoxyglucose, arsenic and oligomycin were not used.
PLEASE HELP ASAP!!!
The question is incomplete as the background of the case and symptoms of Jarod is not provided, however, the missing data required for the question is as follows:
Jared was investigating a drug cartel and ate a meal with one of the suspects. After the meal, he had trouble breathing and felt weak and dizzy. Jared may have been poisoned. He is being taken to the CIA hospital for treatment. You are a medical toxologist working for the CIA. It is your job to find out what poison was given to Jared and try to save his life. Patient: Jared Sondheim Age: 32 Occupation: CIA Agent Symptoms: Muscle Weakness Shortness of Breath Dizziness. Jared has arrived at the hospital! It is your job to find out what toxin was used to poison Jared. You can then give him the correct antidote to save Jared's life.
Answer:
Poisning by 2-deoxyglucose syops the glycolysis process which leads to cardiovascular and respiratory symptoms. Due to property of inhibiting the enzyme reqquired for glycolysis, glucokinase. So, there is no ATP production takes place.
Arsenic poisoning inhibits the second stae of cellular respiration, the Krebs cycle which leads to pyruvate accumalation. The symptoms associated with arsenic are diarrhea, sking tone, abdomunal pain, and muscle cramps.
Oligomycin is used as an antibiotic to inhibit proton ATPase present in mitochondria membrane which blocks ATP formation. Watery eyes, cough, congestion in chest and nose are sysmptopms of oligomycin poisining.
The symptoms cyanide poisoning are dizziness, short breath, nd muscle weakness which matches with the symptoms of jarod.
Water is classified as an inorganic compound because it
A) does not contain carbon
B) does not contain nitrogen
C) contains hydrogen
D) contains oxygen
Water is classified as an inorganic compound because it A) does not contain carbon.
Why is water an inorganic compound?Water is considered an inorganic compound because it doesn't have carbon in it and is represented as H2O.
Inorganic compounds are substances that don't have carbon-hydrogen (C-H) bonds.
Even though water has other elements like hydrogen and oxygen, it's still classified as inorganic because it lacks carbon, which sets it apart from organic compounds.

Carbon dioxide is used by plants for why
Answer: they use carbon dioxide to help them grow.
Explanation:
Answer:
In a process called “photosynthesis,” plants use the energy in sunlight to convert CO2 and water to sugar and oxygen. The plants use the sugar for food—food that we use, too, when we eat plants or animals that have eaten plants — and they release the oxygen into the atmosphere.

Which best explains how nutrients, salt, sediment and pollutants get into estuaries and oceans?
A. from rivers and streams flowing into estuaries and oceans
B. from organisms living and dying in estuaries and oceans
C. from asteroids and comets impacting Earth at estuaries and oceans
D. from precipitation falling over the estuaries and oceans
Rivers take nutrients, salts, sediments, and pollutants from their source at high altitudes, to estuaries and oceans, where they end. The correct option is A. from rivers and streams flowing into estuaries and oceans.
-----------------------------
A river is composed of three main courses:
The highest course ⇒ near the source.
The medium course
There is a low slope. There is a decrease in the speed of the waters, the erosive effect, and the dragging capacity. The flow increases due to the contribution of tributaries. The valley widens.The low course
It is near the mouth, where the slope is low, and the river speed decreases notoriously. There are wider valleys -plains- and wide meanders. The most characteristic feature of this part of the river is the deposit of the last materials that have been uprooted and transported in the previous phases. Hight sedimentation degree.So, from their source at different latitudes and altitudes, rivers go through different states and, as they do so, they carry with their wildlife, sediments, suspended elements, available nutrients, and dissolved oxygen, among others.
As streams pass near farmlands, cities, factories, they also carry pollutant elements, such as chemicals, microbeads, plastics, etcetera.
These elements characterize by their durability in time and resistance, which means that once in the river, they end up in the oceans, where they remain for centuries.
According to this explanation, the option that best explains how nutrients, salt, sediment and pollutants get into estuaries and oceans is option A. from rivers and streams flowing into estuaries and oceans.

Answer:
Forests. Photosynthesis removes carbon dioxide naturally — and trees are especially good at storing carbon removed from the atmosphere by photosynthesis
Explanation:
Plants are involved in the Carbon Cycle by absorbing Carbon out of the atmosphere in order to photosynthesize. The Carbon is used during the photosynthesis. It gets back in the environment by a plant's breathing process.

Which is not a function of the respiratory system?
A. Transports blood throughout the body
B. Controls your breathing
C. Takes in oxygen into the body
D. Removes carbon dioxide from the body
Transports blood throughout the body is not a function of the respiratory system. Thus, option A is correct.
What is circulatory system?
The circulatory system transports oxygen that the respiratory system brings into the body and the circulatory system which is made up of the heart and vessels such as veins and arteries carry oxygen, nutrients and hormones to other parts of the body. The respiratory system deals with bringing in the oxygen into the body for use which is then distributed by the circulatory system to various parts.
According to my research on studies conducted by various medical professionals, I can say that based on the information provided within the question the main function of the respiratory system is to supply the body with oxygen and remove carbon dioxide. This process is done through many different organs, the main one being the lungs which takes the oxygen and disperse it through the bloodstream.
Therefore, Transports blood throughout the body is not a function of the respiratory system. Thus, option A is correct.

Explanation:
Read the instructions for this self-checked activity. Type in your response to each question, and check your answers. At the end of the activity, write a brief evaluation of your work. Activity Plasmid, a DGFPuy developed by Clontech, contains a gene for the green fluorescent protein (GFP) that comes from the bioluminescent jellyfish Aequora victoria. This gene allows the jellyfish to produce a protein that fluoresces, or glows, under ultraviolet light. GFPuv is used as a vector to transform E.coli bacteria. The GFP gene of GFPuv is switched on in the presence of lactose. The plasmid also contains a gene for ampicillin (antibiotic) resistance. Cells with Amor produce a protein that decomposes ampicillin and enables them to survive in an ampicillin environment. Perform the following steps in a laboratory:
1. Introduce the plasmid PGFPUV in E.coli cells by subjecting them to heat shock in the presence of calcium chloride.
2. Spread samples of these cells on four sterile agar plates. Three plates should contain nutrient agar (NA) and one should contain Luria Bertani agar (LB) NOTE LB agar contains lactose. NA contains glucose. Based on the treatment meted out in each plate, write down your observations and conclusions. Compare the results with your peers.
