Answer:
The correct answer is ''insufficient intracellular quantities of ATP due to excessive consumption''
Explanation:
The energy source for the muscle to contract efficiently is adenosine triphosphate (ATP). When ATP is metabolized, energy is obtained. Under normal conditions, the muscle has a sufficient energy reserve to support a limited time of maximum activity. When this reserve is depleted, the body activates other metabolic pathways to achieve more ATP. Glucose is activated first, then carbohydrates, and last - only if the exercise is prolonged - lipids (fats). The muscle, therefore, ends up transforming this ATP into the necessary energy.Whether our body uses more fat or more glucose / glycogen as fuel will depend, above all, on the intensity and duration of physical exercise. The body uses more fat the more gentle and prolonged the exercise; while, the more intense the sport, the more important the need for glycogen will be.Muscle fatigue is the inability or lack of strength to continue doing a certain activity. It happens when the muscles are not strong enough to continue. Specifically, when carrying out a physical activity, the active muscle requires oxygen and energy reserves of glycogen; When the intensity of the activity is increased, this need for oxygen increases, exceeding the levels that the transport system is capable of providing.This situation leads to the active muscle looking for another source of energy, increasing lactic acid which, in turn, it develops a metabolic acidosis that can lead to the breakdown of muscle fiber. ATP is obtained from the oxidative degradation of metabolic substrates such as muscle glycogen, serum glucose, free fatty acids originating from muscles or adipose tissue, being characteristic of muscle fiber, the consumption of ATP, and the production of ADP and Pi, much faster than it regenerates.

Write a supported hypothesis of how the body would react if the peripheral nervous system was shut down while the central nervous system continues to function.
Explanation:
The real magnitude of this challenge can perhaps be best judged by considering the structural and functional complexity of the human brain and the bewildering complexity of human behavior. The human brain is thought to be composed of about a hundred billion (1011) nerve cells and about 10 to 50 times that number of supporting elements or glial cells. Some nerve cells have relatively few connections with other neurons or with such effector organs as muscles or glands, but the great majority receive connections from thousands of other cells and may themselves connect with several hundred other neurons. This means that at a fairly conservative estimate the total number of functional connections (known as synapses) within the human brain is on the order of a hundred trillion (1014). But what is most important is that these connections are not random or indiscriminate:
They constitute the essential "wiring" of the nervous system on which the extraordinarily precise functioning of the brain depends. We owe to the great neuroanatomists of the last century, and especially to Ramón y Cajal, the brilliant insight that cells with basically similar properties are able to produce very different actions because they are connected to each other and to the sensory receptors and effector organs of the body in different ways. One major objective of modern neuroscience is therefore to unravel the patterns of connections within the nervous system—in a word, to map the brain.

What are wetlands?Wetlands are defined as areas where water either completely covers the soil or is present either at or near the surface of the soil throughout the entire year or for varying amounts of time at different times throughout the year, including during the growing season.
Our water is cleaned by wetlands because they filter out sediments, other pollutants, and even chemical contaminants. Additionally, wetland areas act as a filter for and a processing facility for excess nutrients that may run off from agricultural and development sites. Historically, people have referred to wetlands as "the kidneys of our watershed."

Answer:
The correct option is ( have a respiratory system with spiracles connecting to tracheae).
Explanation:
The class INSECTA are under the phylum arthropoda which is the largest phylum in the animal kingdom. The insects are mainly land animals, they are widespread and adapted to all types of environment. They are also the only invertebrates that can fly. Examples of insects include: ants, butterflies, beetles, aphids and grasshoppers.
An insect has a well-defined head, thorax and an abdomen. The head had six segments and bears a pair of jointed antennae, compound eyes, simple eyes and mouthparts. The thorax had three segments, each bearing a pair of jointed walking legs. The abdomen has eleven segments and may have sensory and reproductive structures.
An insect carries out gaseous exchange by means of a network of open air tubes or TRACHEAE inside it's body. These tubes have openings called SPIRACLES to the exterior. Therefore the insects have an respiratory system with spiracles connecting to tracheae.

What are the methods of waste disposal ? Write in briefly.
Answer:
Methods of waste disposal are :-
Biogas plant: - Biodegradable material is used to produce biogas and manure.
Sewage treatment plant: The drain water is treated at plants before adding it to river.
Land filings: - The waste are buried in low-lying areas and compacted with bulldozers.
Composting: - Organic waste are filled in compost pit to make compost for plants.
Recycle: - This means that you collect plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesizing or extracting fresh plastic, paper, glass or metal. In order to recycle, we first need to segregate our wastes so that the material that can be recycled is not dumped along with other wastes.
Reuse: - This is actually even better than recycling because the process of recycling uses some energy. In the ‘reuse’ strategy, you simply use things again and again. Instead of throwing away used envelopes, you can reverse it and use it again. The plastic bottles in which you buy various food-items like jam or pickle can be used for storing things in the kitchen.
Refuse: -This means to say No to things people offer you that you do not need. Refuse to buy products that can harm you and the environment, say No to single-use plastic carry bags.
Repurpose - This means when a product can no more be used for the original purpose, think carefully and use it for some other useful purpose. For example, cracked crockery, or cups with broken handles can be used to grow small plants and as feeding vessels for birds.

10 differences between animal cells and plant cells
Answer:
Following are the difference to the given question:
Explanation:
Plant cells have a wall of a cell, while cells of animals wouldn't. Cell membranes offer plants support and shape.Chloroplasts in plant cells do not occur, however, in animal cells. Chloroplasts allow plants can grow things via photosynthesizing.Plant cells typically get a vacuole(s) that is one or even more big, whereas animal cells are vacuous, whether any.Large vesicles assist shape the plant and enable food and water to be store for future use.In animal cells, the storing function takes a smaller part and the vacuoles, therefore, are smaller.A plant cell is square in its structural way and an animal cell is often spherical and irregular.The cell of a plant has a vesicle in its big form which is significantly smaller than the plant cell, as well as the animal cell was the or more vacuoles. In general, a vacuole is a storage area for the cells to store water.There is no chloroplast inside the animal cell. Chloroplast is a plant cell that produces photosynthesis from its food. The plants have a green color.The nucleus is located throughout the cell of the plant on the other edge of the peripheral cytoplasm, while the nucleus is in the animal's core.Plant cells store food of starch while animal cells store food of glucose.The mitochondria in the plant are fewer and also have tube cristae, whereas the animal cells have grown in various.Which statement correctly compares nucleid acids and corbohydrates?

If an area has very little permeability, such as a city where the ground is mostly concrete, what will happen to most of the rainwater?
A. It will become groundwater.
OB. It will be pumped into underground reservoirs by large machines.
C. It will become runoff.
D. The type of surface it falls on does not affect rainwater.
Answer:
C
Explanation:
The water won't be able to penetrate the ground so can't become ground water and reservoirs are usually above ground not underground so it will become run off.
Permeability is the ability of the substances to get diffused easily across the surface. The concrete ground results in the rainwater becoming runoff. Thus, option C is correct.
What is permeability?Permeability is the capacity of the water or any fluid to pass and diffuse across the substances or any membrane to get from the higher to lower concentration.
The concrete ground and roads are not permeable and do not allow water to pass through the material and effects the collection of the rainwater through infiltration.
The rainwater is unable to filter into the groundwater and becomes runoff. This runoff gets accumulated on the roads and can even lead to floods and drain blockages.
Therefore, option C. the less permeable roads cause rainwater to become runoff.

The water cycle is a closed system, meaning no water enters from beyond the system nor leaves the
system. What does that say about the importance of keeping water on Earth free from pollution?
Answer:
there are no possible changes adaptations
Explanation:
what i mean by that is if a substantial amount of pollution enters the water cycle its going to be nearly impossible for it to get out
If water present on earth is polluted anywhere in the cycle, it starts affecting the system of water and percolation as well as plants become limited that what they will do in order to clean the water. It is possible that if ground is polluted than water will also get polluted. It means that the water present on earth is same the water present from the beginning and will continue to be the same water that is available.
What is groundwater?Groundwater has been defined as water present in the underground water below the soil as well as in the cracks of the earth. The percentage of freshwater in the world would be 30%. There are mainly three types of groundwater and these are hand-dug wells, as well assprings, and drilled boreholes.
The water stored under the ground has obtained from the rain and stored in the ground so that it can be used later. Ground water has very clean and fit for drinking and the reason could be the soil present on top and work as filter and the groundwater is free from all microorganisms.
Therefore, If water present on earth is polluted anywhere in the cycle, it starts affecting the system of water and percolation as well as plants become limited that what they will do in order to clean the water.
