The difference between habituation from a neural perspective is that habituation refers to the fading of the response over the course of monotonous stimulation, and sensitization refers to processes of increased response.

Habituation is an example of non-associative learning in which there is an automatic decrease in the intensity of a response to a repetitive, weak stimulus, without serious consequences, which allows, for example, ignoring stimuli such as noise, the ticking of a clock, etc.

With this information, we can conclude that the difference between habituation from a neural perspective is that habituation refers to the fading of the response over the course of monotonous stimulation, and sensitization refers to processes of increased response.

Answer:

C

Explanation:

energy cannot be created nor destroyed; the same amount of work or energy you put in something, the same you're gonna get back, however all of it you cannot use because it will transferred to other forms of energy also. Therefore, the amount cannot be more or less, so it would have to be equal.

(Technically A is also correct but C is more precise so I'd assume C would be the superior answer)

Answer:

the CORRECT answer is A. You can never get more energy out of a system than you put into a system. <3

Answer:

Mechanical barriers — which include the skin , mucous membranes , and fluids such as tears and urine — physically block pathogens from entering the body. Chemical barriers — such as enzymes in sweat , saliva , and semen — kill pathogens on body surfaces.

Physical barriers and chemical barriers are two types of barriers in the immune system. These barriers help prevent the entry of pathogens into the body. There are differences between physical and chemical barriers.

Physical barriers are physical structures that prevent the entry of pathogens into the body. These barriers include the skin, mucous membranes, and cilia. The skin is the most significant physical barrier. It covers the entire body and serves as a barrier against pathogens. The skin has a few layers that prevent the entry of microbes.

Additionally, the skin has sebaceous and sweat glands that produce sebum and sweat, respectively. These secretions have antimicrobial properties. Mucous membranes are another physical barrier. They line various parts of the body, such as the respiratory tract, gastrointestinal tract, and reproductive system.

They secrete mucus, which traps microbes and foreign particles. Cilia are hair-like structures that line the respiratory tract. They move in a coordinated manner and help remove microbes from the respiratory tract.

Answer:

All of the decomposer organisms in the compost ecosystem are linked by a “what eats what” food web, wherein organisms are classified according to what they eat.

Explanation:

Anaerobic decomposition takes place in nature, as in the decomposition of the organic muds at the bottom of marshes and in buried organic materials to which oxygen does not have access. Intensive reduction of organic matter by putrefaction is usually accompanied by disagreeable odors of hydrogen sulfide and reduced organic compounds which contain sulfur, such as mercaptans (any sulfur-containing organic compound).

When organic materials decompose in the presence of oxygen, the process is called “aerobic.” The aerobic process is most common in nature. For example, it takes place on ground surfaces such as the forest floor, where droppings from trees and animals are converted into a relatively stable humus. There is no accompanying bad smell when there is adequate oxygen present.

Aerobic oxidation of organic matter produces no objectionable odor. If odors are noticeable, either the process is not entirely aerobic or there are some special conditions or materials present which are creating an odor. Aerobic decomposition or composting can be accomplished in pits, bins, stacks, or piles, if adequate oxygen is provided. Turning the material at intervals or other techniques for adding oxygen is useful in maintaining aerobic conditions.

Explanation:

Answer:

1. The reason there is energy released in the process is because the products formed (ADP and hydrogenphosphate/phosphate) have stronger covalent bonds (plus intermolecular forces with the surrounding solution and dissolved ions) than the starting materials.

2. The end product of oxidative phosphorylation is ATP and water. ATP synthesis is coupled with the transfer of electrons to O2, which combines with protons to form water. Phosphorylation is the chemical addition of a phosphoryl group (PO3-) to an organic molecule. The removal of a phosphoryl group is called dephosphorylation. Both phosphorylation and dephosphorylation are carried out by enzymes (there are enzymes involved). kinases and phosphatases, From the family of Enzymes.

Answer:

An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.

Explanation:

Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.

Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

B. Explosive eruptions

Explanation:

An eruption of highly viscous (very sticky) magma tends to produce steep-sided volcanoes with slopes that are about 30–35°.

Explosive eruptions generally involve magma that is more viscous and has a higher gas content. Such magma is often shattered into pyroclastic fragments by explosive gas expansion during an eruption. Volcanic eruptions may fall into six major types: Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian.

Answer: A. We can be sure that we are autonomous, self-determining agents.

Explanation:

Answer:

True

Explanation:

1 - All living cells do indeed divide through mitosis, meiosis, or binary fission. Look at how we’re created through our  cells merging in meiosis, how our skin cells replicate and divide in mitosis, and how bacteria replicates in binary fission. However, we question this by asking where the first cells came from (if you aren’t religious, at least).

2 - All living things are made up of at least one cell, the smallest ones being prokaryotes.

3 - A cell does hold all the functions of life on its own, as we define the functions of life through MRHGREN (metabolism, respiration, homeostasis, growth, reproduction, excretion, and nutrition). However, we can question this by looking at viruses as they are smaller, yet are not considered living as they need to have a host cell in ordered to perform the functions.

Yes, living things are made up of cells.

Living organisms are made up of cells. Cells are the structural and useful units of all living organisms. In 1665, Robert Hooke determined the lifestyles of cells through the use of the microscope, which in addition paved the way for the invention of various different microscopic organisms.

A cell is the simple unit of lifestyle as we know it. it is the smallest unit able to the impartial replica. Robert Hooke counseled the name 'cell' in 1665, from the Latin cella that means storeroom or chamber, after using a very early microscope to observe a piece of cork.
