Some humans are using more than their fair share of water and it is having a huge impact on the environment. People tend to let their water run while brushing their teeth or shaving, and those are just two of the major problems. There may also be leakages, which can waste gallons among gallons of water. Wasting water hurts humans, it leaves them with less accessible, usable water. Additionally, wasting too much water can hurt the local environment as it drains too much water away from the natural ecosystem.
Answer:
DNA is found in the nucleus of a cell in two different forms, depending on whether or not the cell is going through mitosis (cell division). When a cell is not going through mitosis, DNA is in a long, loosely coiled form called chromatin.
Explanation:
Answer: The monosaccharides that are correctly paired with their class are (A) fructose : hexose ketose, (C) glyceraldehyde : triose aldose and (F) dihydroxyacetone : triose ketose.
Explanation: Monosaccharides are classified into two: aldose and ketose. In open chain form, monosaccharides have unbranched chains in which all the carbon atoms are linked by single bonds, one of the carbon atoms is double bonded to an oxygen atom to form a carbonyl group and each carbon atom has a hydroxyl group. An aldose is a monosaccharide in which the carbonyl group is at the end of the carbon chain while a ketose is a monosaccharide in which the carbonyl group is at any other position. A triose is a sugar with three carbon atoms, sugars with four, five, six and seven carbon atoms are known as tetrose, pentose, hexose and heptose respectively.
Fructose is a hexose ketose, erythrulose is a tetrose ketose, glyceraldehyde is a triose aldose, erythrose is a tetrose aldose, ribose is a pentose aldose while dihydroxyacetone is a triose ketose.
Answer:
Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere.
Explanation:
The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them.
Sunspots can be very large, up to 50,000 kilometers in diameter. They are caused by interactions with the Sun's magnetic field which are not fully understood. But a sunspot is somewhat like the cap on a soda bottle: shake it up, and you can generate a big eruption. Sunspots occur over regions of intense magnetic activity, and when that energy is released, solar flares and big storms called coronal mass ejections erupt from sunspots.
Answer:
Explanation:
Smaller cells, with a larger surface area to volume ratio, are more efficient for diffusing materials in and out because, as a cell grows, the volume grows faster than the surface area.
