B. Brine shrimp are healthier if they are fed yeast rather than algae.
I understand that water is always on the move. From the time the earth was formed, it has been endlessly circulating through the hydrologic cycle. Groundwater is an important part of this continuous cycle as water evaporates, forms clouds, and returns to earth as precipitation. The concept of how at a certain depth the ground, if it is permeable enough to allow water to move through it, is saturated with water.
Over 50% of the United States population depends on groundwater for drinking water. Groundwater is also one of our most important sources of water for irrigation. Unfortunately, groundwater is susceptible to pollutants.<span>Drinking contaminated groundwater can have serious health effects. Materials from the land's surface can move through the soil and end up in the groundwater. For example, pesticides and fertilizers can find their way into groundwater supplies over time. Road salt, toxic substances from mining sites, and used motor oil also may seep into groundwater. In addition, it is possible for untreated waste from septic tanks and toxic chemicals from underground storage tanks and leaky landfills to contaminate groundwater. Diseases such as hepatitis and dysentery may be caused by contamination from septic tank waste. Poisoning may be caused by toxins that have leached into well water supplies. Wildlife can also be harmed.</span>
We don't know how much water there is, how fast we're depleting aquifers, or how long we can use this resource before devastating effects take place, like drying up of wells or rivers. I say this because new research has found that the world's sources for groundwater could be depleted before the year 2050.Groundwater is the largest freshwater resource around the world, but as demand is increasing, availability is decreasing.
you should read it and edit some words to make it more "you".
Answer:
1) give shape to cells lacking a cell wall;
2) allow for cell movement,e.g. , the crawling movement of white blood cells and amoebas or the contraction of muscle cells;
3) movement of organelles within the cell and endocytosis;
4) cell division
Explanation:
Answer:
A microaerophilic organism grows only in the middle depth area of a Fluid Thioglycollate Medium tube because the mid area of the tube has moderate levels of oxygen and significantly higher amounts of carbon dioxide.
Explanation:
A microaerophile organism is one that cannot survive or thrive in a region with normal levels of atmospheric oxygen. It prefers environments with a lower concentration of oxygen and higher amounts of carbon dioxide.
Fluid Thioglycollate Medium tube is used during experiments to determine which organisms are aerobes (that is can thrive well in and require oxygen to survive), from those which are anaerobes (cannot tolerate oxygen and may die in its presence) and microaerophilic organisms.
At the bottom of the Fluid Thioglycollate Medium tube, there is zero oxygen whilst at the top, there is lots of oxygen. Towards the midsection, there is less oxygen and more carbon dioxide. The Thioglycollate mixture contains the following:
- Sodium thioglycollate
- Thioglycolic acid
- L-cystine,
- Methylene blue, and
- 0.05% agar.

The three types of endocytosis is phagocytosis, pinocytosis, and receptor mediated endocytosis.
