Answer: the cell divides.
Explanation:
During DNA Replication, the DNA strand that has the bases 3'ATACGC5' produces a strand with the bases 5'TATGCG3'
Answer: Option B
<u>Explanation:</u>
The DNA Replication produces the newly formed two complimentary base pair strand from the two template base pair strand, so basically the already existing DNA strand is replicated, in order to produce complimentary DNA strand, with the template giving one strand to new each.
Thereby, here the given base was 3' ATACGC 5' so the first thing to produce the strand will be that the coding end will be reversed so the 3' end will have 5' end and 5' end will have 3' end. Then A bonds with T and T bonds with A and, so C bonds with G and G bonds with C, therefore, ATACGC will produce TATGCG. Thereby, answer would be 5'TATGCG3'.
Circulation of the blood is crucial in the body since it helps in supply of nutrients and oxygen to all parts of the body. It is these nutrients and oxygen that are key in the activities of a cell or a tissue without which the cells wont efficiently carry out their functions.The inability of the body to supply blood and oxygen to the body cells as required is known as hyperfusion. Hyperfusion is caused by inadequate perfusion of the body tissues and thus resulting to inefficient supply of nutrients and oxygen gas to the body cells and tissues.
Answer:
Class I: Hepaticopsida ( Liverworts)
Class II: Anthocerotopsida ( Hornworts)
Class III: Bryopsida ( Mosses)
Explanation:
Bryophytes are small plants that grows in moist and shady places.They don't attain great heights because of absence of roots, vascular tissues, mechanical tissues and cuticle. They are terrestrial but require external water to complete their life cycle. Hence they are called as the" amphibians" of the animal kingdom.
Class I: Hepaticopsida or Hepaticae
- Gametophytic plant body is either thalloid or foliose. If foliose the lateral appendages are without midrib.
- Rhizoids without septa
- Each cell in the thallus contain many chloroplasts
- Sex organs are embedded in the dorsal surface
- Capsule lacks columella
- Sporophyte may be simple having only one capsule or differentiated into root, seta and capsule
- It has 4 orders: Calobryales, Jungermanniales, Spherocarpales and Marchantiales
Class 2: Anthocerotae or Anthocerotopsids:
- Gametophytic plant body is simple, thalloid;thallus dorsiventra without air chambers shows no internal differentiation of tissues
- Scales are absent in the thallus
- Each cell of the thallus possess a single large chloroplast with a pyrenoid
- Sporophyte is cylindrical only partly dependent on gametophyte for its nourishment. It is differentiated into bulbous foot and cyclindrical capsule. Seta is meristematic.
- Endotheciumforms the sterile central column in the capsule. It have ony one order Anthocerotales
Class 3: Musci or Bryopsida
- Gametophyte is differentiated into prostrate protonema and an erect gametophores
- Gametophore ids foliose, differentiated into axis and lateral appendages like leaves but without midrib.
- Rhizoids are multicellular with oblique septa
- Elaters are absent in the capsule of sporangium
- The sex organs are produced in seperate branches immersed in a group of leaves.
- It has only three orders: Bryales, Andriales and Sphagnales
Bryophytes are used as a packaging material for fragile goods, glasswares etc.Mosses are good source of animal food in rocky and snow clad areas. Decoction prepared by boiling Sphagnum in water is used for the treatment of eye disease.
