In many parts of the United States, homeowners use a significant portion of their energy budget to heat their home in the winter

. It has been determined that lowering a thermostat by 3°F in the winter can reduce the energy costs by about 10 percent in many homes. An individual homeowner lowers their thermostat by 3 degrees exactly halfway through the billing period. For the month that the thermostat was lowered, the heating bill was $95. How much money did the family save in the month in which they lowered the thermostat setting halfway through the billing period?

Answer:

B. $5

Explanation:

$95/10 percent = 9.5

9.5/2 (because it is halfway through the billing period) = 4.75

4.75 rounded up to the nearest tenths place is 5.

The lining of a tubular structure is referred to as the ____ .
sp2606 [1]
In biology, the inner lining of tubular structures is called a lumen.
This can refer to numerous tubular structures in the body, such as the lumen of the veins and arteries, the lumen of the intestines or the tubes in the kidneys.
This term can also be used to describe a space defined by membranes of cell organelles such as the lumen of the mitochondria, the Golgi apparatus, and others.

The most primitive cells are prokaryotic. They are simple, with no organelles and no nucleus. Animal and plant cells are eukaryotic, but they express some differences such as the cell wall, chloroplasts, or centrioles.

---------------------------------------------

<u>BACTERIA CELLS</u>

  • Bacteria are prokaryotic cells.

  • Prokaryotic cells lack a nucleus, nucleolus, and organelles.

  • They only present plasmids, ribosomes, and genetic material in their cytoplasm.

  • DNA not surrounded by membrane

  • They have a cell wall that protects the cell and a cell membrane that surrounds the cytoplasm. Some of them can also present a capsule.

  • Some of them have flagellum.

  • These organisms are capable of inhabiting places with e<em>xtreme temperature, salinity, acidity, or pH, among others. </em>

<u>ANIMAL </u><u>AND </u><u>PLANT CELLS</u>

  • Both the animal and plant cells are eukaryotic.

  • They carry their genetic material in the nucleus and mitochondria.

  • Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.  

However, they have some differences:

⇒Cell wall : <em>A </em><em>rigid structure</em><em> that provides </em><em>support </em><em>and </em><em>protection</em><em>.</em>

• Animal cells do not have a cell wall. They are only surrounded by the cell membrane, which is flexible so they can adopt different shapes.

• Plant cells have a wall, so their shape is usually prismatic and regular. The cell wall is composed mainly of cellulose.

⇒ Chloroplast: these are organelles that accumulate chlorophyll.

• Animal cells do not have chloroplasts because they do not photosynthesize.

• Plant cells have chloroplasts, and they are in charge of the photosynthesis process that allows plants to release oxygen. These organelles use solar light as the source of energy.

⇒ Vacuoles:  

• Animal cells have many and small vacuoles whose function is to store water, ions, and waste intracellular substances.  

• Plant cells have a unique big-sized vacuole that might occupy almost 90% of the cell. Their principal function is to store water and keep the turgidity. When the vacuole gets empty, the plant loses rigidity.

⇒ Other differences are:

  • The animal cell has centrioles, while the vegetable cell does not.  
  • Plasmodium, chromoplasts, and glyoxysomes are present in the vegetable cell but not in the animal cell.
