substitutes, what would be the expected change in the demand for beef, ceteris paribus? (1 point)
It is impossible to tell from the information provided.
The demand for beef would increase.
The demand for beef would decrease.
The demand for beef would be unaffected.
Check Answer
Answer:
C. The demand for beef would decrease.
Explanation:
The demand for beef would be unaffected be the expected change in the demand for beef, ceteris paribus. The correct option is C.
Thus, Consumers might be more likely to pick vegetarian options over beef due to cost considerations.
As a result of recent technological advancements that have made vegetarian meals more affordable to manufacture.
All else being equal (ceteris paribus), this shift in consumer preferences brought on by the relative affordability of vegetarian meals is expected to lead to a decline in the demand for beef.
Thus, The demand for beef would be unaffected be the expected change in the demand for beef, ceteris paribus. The correct option is C.

compare and contrast classical and operant conditioning
In classical conditioning, the involuntary response is seen, while operant conditioning is based upon the learning experience. An organism will perform more or less based on its experience with operant conditioning.
What are classical conditioning and operant conditioning?In classical conditioning, the stimulus is given and an involuntary response is observed. The Pavlov experiment on dogs is one example. He gave food to the dog and rang the bell at the same time for some days. After that, he only rang the bell, and the dog salivated without the food. Here, salvation is an involuntary response to the stimulus (bell ringing).
In operant conditioning, animals perform actions based on their experience. Example: A mouse is put in a box with an electric supply and food supply. When the mouse accidentally presses the electric switch, it gets an electric shock. This is negative reinforcement, and the mouse is less likely to perform the same function again. When it pushes the food lever, the food comes from the food box. This is positive reinforcement. The mouse is more likely to perform this.
Hence, in classical conditioning, the involuntary response is seen. Operant conditioning is based on learned experience.

the area of the brain stem that is important in controlling breathing is the:
Answer:
Medulla.
Explanation:
The primary role of the medulla is regulating our involuntary functions that keeps us alive such as breathing, swallowing and heart rate. As part of the brain stem, it also helps transfer neural messages to and from the brain and spinal cord. It is located at the junction of the spinal cord and brain.

The respiratory center is medulla oblongata. It is involved in minute to minute control breathing.
What parts are involved in the brain stem ?
Brain stem is made up of pons and the medulla oblongata.
The apneustic and the pnuemotaxic centers of pons work together to just control rate of the breathing. In that the medulla just sends the signals to muscles that just initiate the inspiration and the expiration and just controls the nonrespiratory in the air movement of the reflexes like coughing and sneezing.
The cerebellum is well known to just be the part of neuronal circuitry that is just activated in the respiratory challenges that are such as the hunger for the air but are not been made to be involved in control of the spontaneous and the unobstructed breathing .

Explanation:
Well, light is the main source of food for plants along with the addition of carbon dioxide.
Answer:

IT is because animals and plants dont need darkness cause it is of no use to them. locomotion is only there in animals so it wont benefit both. and for light animals dont need it while plants do. so the only option that benefits both is option a food.

why do chloroplasts make energy carriers during the light reactions?
Answer:
consist of array of chlorophyll molecules. *** The absorb energy excited electrons to a higher energy level. ... *** As H+ diffuse through ATP synthase, down their concentration gradient, the enzyme uses the energy of the moving ions to ATP.
Explanation:
Chloroplasts make energy carriers such as NADPH in which the light energy is caught up. Together with carbon dioxide they are used to synthesis glucose during light reaction in photosynthesis.
What is light reaction in photosynthesis ?The first series of events that start the process of photosynthesis require light and are referred to as light reactions or light-dependent reactions since they depend on light as their energy source.
Light energizes the electrons in the chlorophyll molecule as it reaches the chloroplast. These electrons accelerate to higher energy levels because they have taken in or caught that energy and are now carrying it. Excited electrons have high energy. Who wouldn't be thrilled to have the capacity to sustain life?
Chlorophyll is left at a loss when the excited electrons depart to take part in other reactions; eventually, they need to be replaced. In order to break water molecules during that replacement process, an enzyme complex and light are both necessary. Hence, energy carriers plays a significant role in light reaction.

what is excretion meaning
Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life.
In simple terms, the process of eliminating or expelling waste matter.

Name a process in plants that uses oxygen. Compare the raw materials and products of this process with those of photosynthesis
Answer:
Cellular respiration uses oxygen. Comparisons below in explanation.
Explanation:
Plants do both photosynthesis and cellular respiration. They make their own food (photosynthesis) and break it down to make energy (cellular respiration). Cellular respiration uses oxygen, while photosynthesis doesn't (it is a product).
Photosynthesis has this as its general chemical equation:
[tex]6CO_2 +6H_2O[/tex] ⇒ [tex]C_6H_{12} O_6 + 6O_2[/tex]
Cellular respiration has this as its general chemical equation:
[tex]C_6H_{12} O_6 + 6O_2[/tex] ⇒ [tex]6CO_2 + 6H_2O[/tex]
As you can see, the raw materials of cellular respiration (glucose and oxygen) are the products of photosynthesis. The products of cellular respiration (carbon dioxide and water) are the raw materials used in photosynthesis.

select the cell cycle impairments that you predict would lead to cancer. recall that cancer arises from unregulated, repeated cell divisions. choose all that apply.
Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.
Genetic mutations can occur during the life of a cell due to outside factors such as:
The food we eatThe environment we expose the cell toThe substances that touch the cell (e.g skin cells)That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of programmed cell death.
Programmed cell death is what tells a cell when it should stop growing and dividing. This is a regulatory function designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The accumulation of these cells is referred to as cancer.
