Answer:
vacuoles – transport
cell wall – protect
nucleus – control
Explanation:
Vacuole is a small sac containing fluid and helps in the transport of substances within and outside the cell
Cell wall is external to the cell membrane and serves a structural function helping the cell maintain its shape and PROTECTING the cell from damage.
Nucleus is an organelle found in cells of plants and animals. It contains genetic information in DNA or RNA, and CONTROLS the entire life process
Note that mitochondria helps to provide ENERGY to build up substances in the cell NOT DECOMPOSE
In eukaryote cells, it occurs in the mitochondria or chloroplasts. In prokaryote cells, it occurs in the cell membrane.
Explanation:
In a DNA molecule, Adenine forms hydrogen bonds with Thymine and Cytosine forms hydrogen bomds with Guanine.
However in mRNA, Thymine becomes Uracil (T => U)
Therefore every A in the DNA sequence becomes U,
every T in the DNA sequence becomes A,
every C in the DNA sequence becomes G,
every G in the DNA sequence becomes C.
The answer is A.
Answer:
Oxidize organic compounds AND use organic compounds as terminal electron acceptors. (Ans. E)
Explanation:
Anaerobes are the organism that does not require oxygen for their growth. The anaerobes are subdivided into three main classes:
1) Obligate anaerobes: These organisms use anaerobic metabolism to grow and killed in the presence of oxygen. Obligate anaerobe examples are Clostridium and Propionibacterium.
2) Facultative anaerobes: These organisms prefer to grow using aerobic metabolism processes and switch to anaerobic metabolism in the absence of oxygen. An example of facultative anaerobic bacteria is Lactobacillus.
3) Aerotolerent anaerobes: These organisms use anaerobic metabolism to grow and can survive in both conditions (oxygen and oxygen-free environment).
Anaerobic bacteria, oxidize organic compounds rather than oxygen & use organic compounds as terminal electron acceptors. Anaerobic bacteria release hydrogen sulfide gas as they decompose algae in the water. This process is also known as Anaerobic Respiration, in which formation of ATP without oxygen.
Intestinal gland secretes intestinal juice ,it contains enzymes and their role is to decompose food more and then conduct them into the large intestine or by intestinal absorption to the blood
