The blood carries the oxygen into the cell, which pass through the entire body. Smaller crustaceans need gas to obtain oxygen. Other crustaceans use their gills. Usually gills are attached to the base of the thoracic appendages. The act of beating the appendages creates a gush of water that flood into the gills.
The solutes are called electrolytes, which maintain healthy bodily functions. When an electrolyte dissolves it breaks up into ions. There are millions of electrolytes within a cell. Water moves inside and outside the cell, with osmotic pressure, which is the force that pulls fluid from one place to another. The level of osmotic pressure is equal in the intracellular fluid, and the extracellular fluid.’ (Study.com, 2015) ‘Osmotic pressure is vital within the human body because it allows water to enter a cell if there is lack of water, and vice versa, if there is too much water within one cell, the osmotic pressure will allows the electrolytes to exit a cell.’ (Study.com, 2015) ‘Intracellular fluid has important functions, it transports food within the cells, it also brings waste products from the cells so that they can be picked up and excreted from the body, and it maintains the shape and size of the cell.’ (Nursing411.org, 2015) ‘Extracellular fluid is located outside the body cells.
The cells become leaky; sodium slowly began to leak into the cells, and potassium leaked out. Question C: Which intracellular organelles have membranes as part of their structure? How would the breakdown of the membranes of these structures affect the function of Joseph’s heart cells? All intracellular organelles have membranes as a part of their structure. The breakdown of the membranes of these structures affect the function of the heart because the special calcium ATPase’s had stopped moving calcium from the cytosol into the endoplasmic reticulum of his cardiac muscle cells.
Aquatic environments are generally split into three categories; fresh water, marine (salt water) and estuarine (a combination of salt and fresh water). The organisms that live in each of these environments have specific adaptations that allow them to respond to changes in their surrounds. Fish generally prefer either fresh water or salt water and are unable to cope with a change from one to the other. For example the cells in fresh water fish are saltier than the surrounding water, so due to osmosis (the diffusion of water through a semi-permeable membrane) water is constantly flowing into its body. For this reason fresh water fish require very efficient kidneys to remove all of the extra water, and methods of maintaining and collecting the salt lost through urination.
Lab 1 – Introduction to Science Exercise 1: The Scientific Method Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organisms require oxygen to survive, it is a necessary component of water systems such as streams, lakes, and rivers in order to support aquatic life. The dissolved oxygen is measured in units of parts per million (ppm). Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from and then answer the questions below. QUESTIONS 1.
As carbon dioxide is released into the water through the respiration of the crayfish it is converted into carbonic acid shown below. CO2 + H20 H2CO3 As more carbon dioxide was released into the water surrounding the crayfish the water became more acidic. We could then measure the amount of CO2, by measuring the amount of a basic solution, in this case sodium hydroxide (NaOH) to neutralize the acid. We used the pH indicator phenolphthalein, which is colorless in acidic solutions and turns red in basic solutions. The more carbon dioxide in the water the more sodium hydroxide was needed to neutralize the solution.
If you drink too much water, your cells can expand and eventually burst, which can be dangerous. Two ways to deal with dehydration Move the dehydrated person to a cool area so he/she can cool down, put a cool cloth on his/her forehead. - Sip water slowly. If you drink too much water, your cells can expand and eventually burst, which can be dangerous. Five ways water is used in the body - Your cells need water to live and survive.
(Calcium ions) are stored in the Sarcoplasmic reticulum. 4. The cause for the release of Calcium is the depolarization of the T-tubules. (Acetylcholine enters the synaptic cleft gap and opens the chemically gated sodium channel that starts an action potential spreading down the sarcolemma of the myofibril. This will cause an action potential to spread down to the T- tubules and “electrical chemical signals = shocks” the sarcoplasmic reticulum into releasing calcium ions.
In part C of the experiment, we were to demonstrate osmosis between distilled water and each of the solutions in the dialysis tubes (water, 0.2 M, 0.6 M, 0.8 M, and 1.0 M sucrose all represented by unknown colors). We hypothesized that all of the dialysis bags except water will increase in mass. This is because the bags will be hypertonic to the distilled water solution in the beaker, meaning that there are more solutes and less water than the surrounding. In a hypertonic condition, water is rushed into the cell (or the dialysis tube in this case) in order to dilute the concentrated solution in the cell. Water would not change in mass because it is isotonic to its surrounding.
Ionic: This contains atoms that can have a positive or negative charge as a result of gaining or losing electrons. Atoms or groups of atoms are called ions and electrolytes. Ions are continuously moving in and out of the cells, as they are often required or eliminated products from thousands of chemical reactions occurring in cells. In solution: Substances are capable of dissolving in liquids are called solutes (the liquid is a solvent and the solute dissolved in the solvent is a solution. Salt dissolves in water because ions become separated by polarised water molecules.
