What is the functions of the digestive, excretory, respiratory, circulatory, and lymphatic systems, and how do they interact to maintain the body's homeostasis?
Explanation:
Food and liquids are processed by the digestive system. After nutrients are absorbed during digestion, the excretory system removes solid waste products, or feces, through the rectum. The excretory system also works with the respiratory and circulatory systems and removes carbon dioxide (CO2) from the body.
Homeostasis, which refers to the body's capacity to maintain a steady internal environment despite changes in the external environment, is a state that is maintained by the respiratory, circulatory, lymphatic, excretory, and digestive systems working in concert. Although each of these systems has a unique job to do, they are all interrelated and dependent on one another to keep the body running smoothly.
What is a digestive system charge of ?The digestive system is in charge of converting food into nutrients that the body can absorb. It consists of the liver, pancreas, small and large intestines, stomach, mouth, oesophagus, and stomach. After then, the circulatory system delivers nutrients to the body's cells.
The kidneys, ureters, bladder, and urethra are part of it. The circulatory system and the excretory system collaborate closely to move waste materials to the kidneys for filtering and expulsion from the body.
The respiratory system is in charge of supplying the body with oxygen and expelling carbon dioxide. It consists of the lungs, trachea, bronchi, nose, and mouth. The respiratory system collaborates with the circulatory system to eliminate carbon dioxide and provide oxygen to the body's cells.
Nutrients, oxygen, and waste products are moved throughout the body through the circulatory system. It consists of the blood, blood vessels, and the heart. To provide nutrition and oxygen to the cells and eliminate waste, the circulatory system collaborates closely with the respiratory and digestive systems.
It is the job of the lymphatic system to remove extra fluid from bodily tissues and transport it back to the circulatory system. It consists of lymphatic organs like the spleen and thymus, lymph nodes, and lymphatic arteries. The lymphatic system contributes to immunological function and aids in the body's defence against illnesses and infections.
Overall, through controlling the body's internal environment, these systems cooperate to preserve homeostasis. For instance, the excretory system eliminates waste while the digestive system supplies nutrients for the body. These nutrients and waste materials are delivered to and removed from the body's cells via the circulatory system. The lymphatic system helps the body fight infections while the respiratory system supplies oxygen for cellular respiration.

3. If muscle contraction were an athletic game, calcium would be the most valuable player. Describe,
using some depth, the roles calcium is serving both inside the muscle fiber and outside at the NMJ.
Answer:
Explanation:
At the NMJ, calcium is responsible for "unlocking" the ligand gated channels, allowing AcH to be released into the synaptic cleft. When AcH binds and the AP moves down the sarcolemma and into the t-tubule, calcium is then released from the sarcoplasmic reticulum into the sarcoplasm. It then binds to the calcium subunit of troponin, causing a confirmational change in tropomyosin, exposing the active sites on actin. This allows the myosin heads to bind, causing muscle contraction.

Utility companies use _ per month, to determine how much energy is being used.
What goes in the blank ?
Answer:
Kilowatt-hour
Explanation:
Energy refers to the amount or quantity of power which is being consumed by an individual, group of people or organization over a specific period of time. As the consumers continue to use energy, they're being charged or made to pay a utility fee regularly for their amount of consumption, which is usually calculated hourly (kilowatts hour or kwh).
Hence, power utility companies use kilowatt-hour (KWh) per month, to determine how much energy is being used.

Heat energy is converted to mechanical energy that’s used for muscle movements.
Answer: Chemical energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.
Explanation:
According to the I law of thermodynamics, energy can neither be created cannot be destroyed but it can only change its form. In the given situation, the energy can only be conserved when it is not lost to the environment. The chemical energy is produced in the body in the form of ATP which is converted into mechanical energy to allow the movement of the muscles during running. So, chemical energy is converted into mechanical energy by this way. The heat energy when directly converted into mechanical energy to induce the movement of muscles the energy will remain conserved and will not lost to the environment.

A person is taken to the emergency room at Baptist Hospital vomiting, bleeding and with severe diarrhea. He complained of a headache, shortness of breath and body aches. The doctor quickly checked the composition of the patient’s blood plasma, the light-yellow liquid that carries salts and enzymes, and determined he was severely dehydrated. Thus, causing a severe loss of fluid in the blood and an increase of blood cell concentration. The doctor prescribed intravenous liquids (IV) and rest.
Based on the patient’s symptoms and doctor’s initial prognosis, how does dehydration affect a person’s blood flow and blood pressure? SC.912. L.14.36
The patient’s blood viscosity would increase, causing blood flow to increase and blood pressure to decrease
The patient’s blood viscosity would decrease, causing the blood flow and blood pressure to remain at a stable rhythm
The patient’s blood viscosity would decrease, causing the blood flow to decrease and the blood pressure to also decrease
The patient’s blood viscosity would increase, causing the blood flow to decrease and the blood pressure to increase
Answer:
The answer is "The patients blood viscosity would decrease, causing the blood flow to decrease in the blood pressure to also decrease".
The correct answer is: The patient’s blood viscosity would increase, causing the blood flow to decrease and the blood pressure to increase.
What is Dehydration?When the body loses more fluid than it takes in, dehydration develops. It occurs when the quantity of water and electrolytes (such as sodium, potassium, and chloride) that the body need to operate correctly are out of balance.
Numerous internal processes, such as controlling body temperature, lubricating joints, transferring nutrients, and getting rid of waste, depend on water.
Dehydration causes the amount of fluid in the blood to decrease, which causes the concentration of blood cells and other components to rise.
Blood gets thicker and flows more slowly as a result of this rise in blood viscosity, which is caused by an increase in blood cell concentration.
As a result, the blood flow decreases, and the resistance to blood flow increases, leading to an increase in blood pressure.
Therefore, in the given scenario, the patient's severe dehydration would cause an increase in blood viscosity, leading to a decrease in blood flow and an increase in blood pressure.

Scientists analyzed data collected over a period of years in a game reserve in South Africa to test the hypothesis that competition with lions limits the abundance of leopards in the same community. The game reserve encompasses a variety of habitats, from open grassland to wooded areas around rivers and streams. It contains most of the indigenous mammal species and an adequate availability of their prey. For the most part, the leopards and lions show similar habitat preferences in the reserve.
The mass of the average lion is about three times that of the average leopard. The scientists analyzed several factors that might influence the abundance of each population, including the sizes of the animals preyed on by each species
Size of Prey Animal Percent of Leopards’ Prey (±2SEx¯) Percent of Lions’ Prey (±2SEx¯)
Small 34 ± 2 3 ± 1
Medium 63 ± 3 23 ± 2
Large 3 ± 1 36 ± 4
Very large 0 38 ± 3
Because competition with lions might affect the population size of the leopards, the scientists also analyzed data on the lion and leopard population sizes in the game reserve (Figure 1).
Required:
Describe what scientists mean when they refer to an ecological community such as that shared by the leopards and lions.
Answer:
The correct answer would be - these are the ecological community that shows the interspecific competition.
Explanation:
In this ecological community, both predators lion and leopards are living together and by the given data and information it is evident that they both share the same habitat and they both depend on the same prey for their food.
This cause competition between both lion and leopard for food and habitat. Such competition or interaction is referred to as the interspecific competitions negatively impacted by the presence of the other because they will have less food.

6. Looking at the chemical equation for anaerobic respiration in the Introduction portion
of this lab, what product of cellular respiration was the gas in the balloon?
NEED HELP
Answer:
Because carbon dioxide is a component of your breath, and when you exhale, you release it.
Carbon dioxide
How do you blow up a balloon? You might know that carbon dioxide is what we exhale into a balloon, but where does it come from? Carbon dioxide is a waste product from a process called cellular respiration, which uses oxygen and sugar to make energy and carbon dioxide.
What is carbon dioxide?Carbon dioxide (chemical formula CO2) is a chemical compound occurring as a colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0.04% (417 ppm) by volume, having risen from pre-industrial levels of 280 ppm. In water it forms an acidic solution due to the formation of carbonic acid (H2CO3). Natural sources include volcanoes, forest fires, hot springs, geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, ice caps, glaciers and seawater. It is present in deposits of petroleum and natural gas. Carbon dioxide has a sharp and acidic odor and generates the taste of soda water in the mouth, but at normally encountered concentrations it is odorless.
As the source of available carbon in the carbon cycle, atmospheric carbon dioxide is the primary carbon source for life on Earth and its concentration in Earth's pre-industrial atmosphere since late in the Precambrian has been regulated by photosynthetic organisms and geological phenomena. Plants, algae and cyanobacteria use energy from sunlight to synthesize carbohydrates from carbon dioxide and water in a process called photosynthesis, which produces oxygen as a waste product

eselson and Stahl relied on equilibrium density gradient centrifugation to resolve the DNA containing 14N from the DNA containing 15N.They started off with DNA in media containing the heavy isotope, then switched to media containing the lighter isotope and allowed DNA replication to take place. Under semiconservative model of DNA replication, after THREE rounds of replication, how many bands of DNA would you see and which band would contain more DNA molecules
Answer:
The correct answer would be - two bands ( one intermediate, and one light)- the light band contains more DNA molecules.
Explanation:
After the switching to the lighter isotope by the second round of replication where light strands are used as template strands, produces the light band of 14N.
After three rounds of semiconservative replication, where template strand contains both heavy and new formed light bands or nitrogen and produces so in a Density gradient, there will be 2 bands one light band and the other intermediate band.

Explanation:
Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur while external regulators speed up or slow down the cell cycle.
What are Proteins?Proteins are large and complex molecules which play many critical roles in the body. Proteins do the work in cells which are required for the structure, function, and regulation of the body's tissues and organs.
Proteins are made up of many smaller units called amino acids, which are linked together in long chains. There are 20 different types of amino acids that can be linked to make a protein.
The sequence of amino acids determines each protein's unique 3-dimensional structure and its specific function. Amino acids are coded for by a combination of three DNA building blocks (nucleotides), which are determined by the sequence of genes.
Thus, internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur while external regulators speed up or slow down the cell cycle.

Answer:
Cattle and egret
Explanation:
Mutualism is a type of symbiotic relationship involving two organisms whose actions cause them to benefit from one another. In other words, both organisms do one another a favour, hence, the relationship is said to be MUTUAL.
- An example of a mutualistic relationship is that of CATTLE AND EGRET. Cattle gets infested by certain parasites like ticks and fleas, which feeds on their blood. Egrets are bird species that flock around cattle to feed on these insect parasites. This relationship is mutual because, egrets help the cattle get rid of their parasite problem (cattle benefits) while the cattle provides food for the egrets when they harbor these parasites on their body (egret benefits).
