D. Is the answer because it has the greatest biodiversity
Answer:
Mitochondria originated when an ameoba like organism engulfed an aerobic proteobacterium capable of cellular respiration.
Explanation:
Endosymbiotic Theory:
- The endosymbiotic theory explains the origin of eukaryotic cells and eukaryotic organelles, particularly the chloroplast and mitochondria.
- According to this theory, a prokaryotic ameoba like organism increased in size and gradually developed infoldings of its plasma membrane. These infoldings gradually developed into an endomembrane that enclosed the genetic material and nucleus.
- This cell then engulfed a proteobacterium capable of cellular respiration. Over time, this cell thrived as oxygen increased in the atmosphere of the Earth. The proteobacterium survived as an endosymbiont and later evolved into mitochondria.
<span>Soil is composed of various materials, such as gravel, sand, silt, clay, and organic material. Each of these substances creates a variety of different soil conditions. Different soil compositions have different properties, which affect water capacity. One of these soil properties is grain size.
Gravel is greater than 2 mm
Sand is 0.5 - 2.0 mm
Silt is 0.002 - 0.005 mm
Clay is less than 0.002 mm
Answer these questions.
A. A soil composed of which particle on the chart would be least effective in allowing water to pass through it?
B. Explain how soil grain size can affect water storage capacity in soils.
C. Explain why a soil composed of a combination of the grains shown would be a better soil for plants than a soil composed of just one type of grain.
D. What purpose does sand serve when mixed with a soil that is made mostly of clay?

<span>One alteration in elimination in the elderly that leads to dehydration is changes in skin. As one ages, the skin becomes thinner and more permeable, allowing fluids to exit the body more easily. This change in skin can cause the elderly to be more susceptible to severe dehydration.</span>
