The best answer is A.
In a lysogenic cycle, the viral DNA or RNA enters the cell and integrates into the host DNA as a new set of genes called prophage. The prophage is passive and non virulent and does not destroy the cell. However if the prophage undergoes any stress or mutation or is exposed to UV radiation, it may adopt the lytic cycle and become infective.
In a lysogenic infection, there are no viral symptoms and it occurs after the viral infection is over. But the viral DNA or RNA remains in the cell and may remain there permanently .
Answer;
-Flagellum (flagella; plural)
Explanation;
-Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea.
-A flagellum is a whip-like structure that allows a cell to move. They are found in all three domains of the living world: bacteria, archaea, and eukaryota, also known as protists, plants, animals, and fungi.
-The primary role of the flagellum is locomotion, but it also often has function as a sensory organelle, being sensitive to chemicals and temperatures outside the cell. Flagella are organelles defined by function rather than structure. Flagella vary greatly. Both prokaryotic and eukaryotic flagella can be used for swimming but they differ greatly in protein composition, structure, and mechanism of propulsion.
Waxing means the moon is getting brighter. It it moving from a New Moon, no light, towards a Full Moon. Also if you see the light of the moon on the right. It will be getting brighter each night until it reaches a Full Moon Then it will start Waning or decreasing in light each night. So the answer is the last one.
Answer:
organelle
Explanation:
All eukaryotic cells have membrane-bound organelles. An organelle is a small structure found in the cytoplasm that carries out specific activities inside the cell
Answer:
Explanation:
Sedimentary rocks are rocks that are formed near the Earth’s surface. It js formed through a sucessive geological processes this include erosion, weathering, dissolution, precipitation, and lithification.
Physical weathering: Sedimentary rocks are layered rocks with many fractures from contracting during cooling. These cracks are opened up as the rock is brought to the surface and it allows water to get in. On freezing the water expands causing the cracks to widen and grow.
chemical weathering. Rain water can be slightly acidic and at times acid rain. This Acid dissolves many minerals particularly in crustal rocks, acid attacks carbonate found in sedimentary rock and feldspar, a principal ingredient of granite dissolving them.
Biological weathering:
Living things also lead to the breakdown of rock into fragments. Roots and burrowing animals physically disrupt rocks leading to the formation of soil.
The results of all the weathering processes is q heap of loose rock fragments and dissolved ions such as salt, bicarbonate, potassium.
The clastics blown away are carried by glaciers from the source region to a catchment area this is called sedimentary basin
