Other molecules such as proteins, starch and sugar are simply too large to diffuse across the membrane. Sometimes, some of these large molecules are transported across the cell membranes by carrier proteins; this does not require energy and as a result is a form of passive transpor
Answer:
<em>Escherichia coli </em>- Facultative anaerobe
<em>Micrococcus luteus </em>- Obligate aerobe
<em>Clostridium sporogenes</em> - Obligate anaerobe
Explanation:
In simple terms, obligate aerobes are organisms that require oxygen to grow and metabolize molecules such as fats and sugars to produce energy. Many animals fall under this category. Other examples are <em>Mycobacterium tuberculosis </em>and <em>Micrococcus luteus</em>.
Facultative anaerobes are organisms (usually bacteria) that can grow both in the presence and absence of oxygen. The most example of this are the <em>Escherichia coli</em><em>.</em>
Obligate anaerobes are organisms (usually microorganisms) that cannot survive when exposed to normal atmospheric concentration of oxygen. Examples are <em>Clostridium sporogenes</em><em> </em>and <em>Clostridium botulinum.</em>
I think the correct answer from the choices listed above the first option. In a polar covalent bond, the distribution of common electrons are <span>not shared evenly due to a greater positive charge from one atom’s nucleus. Hope this answers the question. Have a nice day.</span>
there is no clear evidence about plants evolving in the desert, or fossils of any kind of cactus despite their distribution over a large area. But, scientists are of the opinion that they acquired specific attributes millions of years ago, as a response to the vastly changing climate and conditions.
-Desert plant root system
A typical desert plant has a deep root system, which is a specific physical mechanism. As the roots grow deep down the soil, they absorb soil water, which is then transported to the upper portions of the plant.
-Desert plant leaves
Bear small foliage with waxy surface to minimize transpiration (loss of water through stomatal pores), which in turn, helps to conserve water.
The correct answer is that variable number repeats are used in DNA tests; they have hundreds of possible lengths. Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called, melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.
