Answer:
Microorganisms such as cyanobacteria can trap the energy in sunlight through the process of photosynthesis and store it in the chemical bonds of carbohydrate molecules. The principal carbohydrate formed in photosynthesis is glucose. Other types of microorganisms such as nonphotosynthetic bacteria, fungi, and protozoa are unable to perform this process. Therefore, these organisms must rely upon preformed carbohydrates in the environment to obtain the energy necessary for their metabolic processes.
Cellular respiration is the process by which microorganisms obtain the energy available in carbohydrates. They take the carbohydrates into their cytoplasm, and through a complex series of metabolic processes, they break down the carbohydrate and release the energy. The energy is generally not needed immediately, so it is used to combine ADP with phosphate ions to form ATP molecules. During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons. This oxygen gas is identical to the oxygen gas given off in photosynthesis.
Explanation:
<u>Answer:</u>
<em>I belong to the kingdom Plantae.
</em>
<u>Explanation:</u>
<em>Plantae is one among the five kingdoms in the five kingdom classification. </em>Plants are not mobile organisms unlike organisms of other kingdoms. <em>The roots of plants hold them to the earth and thus they are immobile.
</em>
Being immobile, they cannot run away from potential dangers like mobile organisms. But being autotrophs they make their own food by the process of photosynthesis. <em>Heterotrophs depend on autotrophs for food to obtain energy. </em>
Answer:
2 Ampere
Explanation:
According to Ohm's Law
V=IR
where V is voltage I is current and R is resistance
24=I(12)
I=24/12
I=2 A
To calculate volume, simply multiply length*width*height....
V = 30cm*40cm*200cm
V = 1200cm^2*200cm
V = 240000cm^3
Thus, the volume of the locker would be 240000cm^3
The question is incomplete as it does not have the options which are:
A. Gram-negative bacilli cannot cause harm to the cell; only Gram-positive bacilli can harm the cell.
B. Gram-negative bacilli release endotoxins that cause cell injury and increased capillary permeability.
C. Gram-negative bacilli excrete elaborate exotoxins that interfere with cellular production of ATP.
D. Gram-negative bacilli enter the cell and disrupt its ability to replicate.
Answer:
B. Gram-negative bacilli release endotoxins that cause cell injury and increased capillary permeability.
Explanation:
Gram-negative bacteria are pathogenic in nature due to the composition of their cell wall. Their cell wall contains an additional layer of a molecule called lipopolysaccharides or LPS.
The LPS layer is toxic in nature and is known as endotoxin and is involved in the pathogenicity of the bacteria as the toxin causes the injury to the Endothelial cell membrane of the host cell.
When the bacteria cell is lysed and the LPS circulates in the blood, then LPS binds the receptors and acts on CD14. This attracts the neutrophils at the site and can cause vascular injury due to increased capillary permeability.
Thus, Option-B is the correct answer.
