Enzyme B stays effective at higher temperatures than enzyme A. Therefore, option (C) is correct.
What are enzymes?From the graph, it can be observed that Enzyme B remains effective at higher temperatures, while Enzyme A is less effective at higher temperatures. As the temperature increases, Enzyme A's activity decreases and is less efficient in converting the substrate into product, while Enzyme B remains active at higher temperatures and converts more substrate into product.
Therefore, the conclusion that can be drawn from the graph is that Enzyme B stays effective at higher temperatures than Enzyme A.

If the pair of materials listed below were rubbed together, give the charge that each would have in the same order as listed. use short-form P and N. silk and paraffin wax
Answer:
Simply put, the property of electron affinity refers to the relative amount of love that a material has for electrons. If atoms of a material have a high electron affinity, then that material will have a relatively high love for electrons. This property of electron affinity will be of utmost importance as we explore one of the most common methods of charging - triboelectic charging, also known as charging by friction or rubbing.
Suppose that a rubber balloon is rubbed with a sample of animal fur. During the rubbing process, the atoms of the rubber are forced into close proximity with the atoms of the animal fur. The electron clouds of the two types of atoms are pressed together and are brought closer to the nuclei of the other atoms. The protons in the atoms of one material begin to interact with the electrons present on the other material

Name at least three neuromitters and state the roles of these neuronmitters in human body ? Except acetylcholine, (GABA)and domanine. Please help as soon .
Answer:
Explanation:
The chemical messengers present in the body are known as neurotransmitters. These are the chemicals that the nervous system uses to send and receive information between neurons and muscles. A neurotransmitter can have one of three effects on a neuron:
Excitatory effect, Inhibitory effect, and/or Modulatory effect.
The list of neurotransmitters and their roles are as follows:
Glutamate: This is present in amino acid compounds which are located in the synapses. It functions as an excitatory neurotransmitter, causing neurons to discharge instructions when stimulated in the central nervous system.
Adrenaline: It helps to respond to body's psychological stress and protection mechanism. They are positioned above the kidney and are created by the adrenal glands. They operate throughout the central nervous system and swiftly increase your heart rate and provide oxygen to your muscles.
Serotonin: Serotonin is a crucial brain neurotransmitter that also has a role in the small intestine. In your digestive tract, serotonin increases feelings of contentment after eating and controls your appetite. When you eat anything that doesn't agree with your stomach, serotonin assists your body in getting rid of it.
What are some benefits of social behavior?
Answer:
Social behavior is defined as interactions among individuals, normally within the same species, that are usually beneficial to one or more of the individuals. It is believed that social behavior evolved because it was beneficial to those who engaged in it, which means that these individuals were more likely to survive and reproduce. Social behavior serves many purposes and is exhibited by an extraordinary wide variety of animals, including invertebrates, fish, birds, and mammals.
Social behavior seems to provide many benefits to those who practice it. Studies have shown that many animals are more successful in finding food if they search as a group. This is especially true if food resources are clumped together only in certain places. If more individuals are cooperating in the search, there is a greater chance one of them will find the clump of food. In some cases, foraging in a group makes it easier to capture a prey. Dolphins are known to surround a school of fish and to take turns darting into the center to eat the fish that are trapped in the middle. Many carnivores will band together when they try to capture large prey. Some examples are that wolves will hunt together when hunting moose, and lions will hunt together when hunting large prey such as wildebeests. When these animals are hunting much smaller prey, they will often hunt singly.
Many animals live in social groups partly for protection. Although one baboon might not be able to fight off a leopard, a troop of baboons often is able to do so. In addition, with more individuals cooperating together, some can serve as sentries looking for danger while the other group members are eating or sleeping. Prairie dogs and large flocks of crows normally have some individuals acting as sentries, which makes it nearly impossible to sneak up on a prairie dog town or a flock of crows.
Some animals form social groups to make travel easier. Canada geese and other bird species typically fly in a V formation. Just like bicyclists who ride behind one another in order to reduce wind resistance, the geese fly in formation to reduce the wind they must encounter. In this situation, the lead bird has the most tiring job, which is why several birds usually take turns leading the V. Some animals congregate in close proximity to one another in cold weather in an effort to stay warm. Small birds are sometimes known to huddle so closely they form a single large ball of birds.

Describe and distinguish between the sources of energy utilised by the brain and heart under well-fed and starvation conditions.
Answer:
Brain ----- glucose and amino acids.
Heart ------- fatty acids and triglycerides.
Explanation:
The sources of energy utilized by the brain is glucose under well-fed whereas the sources of energy utilized by the heart under well-fed condition is fatty acids. During starvation, the source of energy used by the brain is amino acids from skeletal proteins when glucose is not available while on the other hand, during starvation, the heart utilized triglycerides as a source of energy in the absence of fatty acids.

What is the path blood takes through the heart, body and lungs.
Answer:
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.
Explanation:
Answer:
1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) aorta –> 14) body.

A scientist claims that he has protected animal test subjects from a newly mutated virus using an experimental vaccine. The experimental vaccine was injected into five animal test subjects. The scientist also injected a placebo vaccine into five other animal test subjects. One month later, all of the test subjects were exposed to the mutated virus. The subjects that received the vaccination showed no sign of the disease and blood tests confirmed the presence of antibodies against the disease, but the subjects given the placebo developed symptoms of this condition. Why did one group have a placebo injected before being exposed to the virus? Choose 1 answer: Choose 1 answer: (Choice A) A They were part of the control group (Choice B) B They would be exposed to a weakened form of the virus (Choice C) C They would be protected from the disease (Choice D) D They were part of the experimental group
Answer:
A. They were part of the control group
Explanation:
In a scientific experiment, the CONTROL GROUP as opposed to the experimental group is the group that does not receive the experimental treatment. This acts as a standard for comparison.
In this question, the EXPERIMENTAL VACCINE is the experimental treatment or independent variable that was added. The five animal test subjects that was injected with this vaccine are called the EXPERIMENTAL GROUP while the other five test subjects that were rather injected with a PLACEBO are called CONTROL GROUPS.
