Answer: Such constant change has characterized Earth since its beginning some 4.5 billion years ago. From the outset, heat and gravity shaped the evolution of the planet. These forces were gradually joined by the global effects of the emergence of life.
Explanation:
Answer:c. Separated DNA is attached to the cell membrane before the cell divides.
Explanation:
The prokaryotes are single celled organisms. These are simple organisms which reproduce through asexual mode of reproduction that is cell division. They do not posses well define nucleus. Thus the genetic material remain in the cytoplasm of the cell. On cell division the genetic material (DNA) is distributed into halves for development of two daughter cells. Due to lack of nucleus and it's associated membrane the separated DNA get attach to the membrane before the cell actually divides.
Answer:
Internal factors include particle-size distribution, organic matter content, mineralogy and water content of the soil. Externally applied forces are generally mechanically applied forces, the primary source of these being vehicular traffic
Explanation:
The correct answer is A - chlorophyll.
It is a green pigment found in the chloroplasts of green plants. Chloroplasts are mostly found in the leaves of green plants and also in some algae.
Plants use chlorophyll to trap light energy from the sun. Without the light energy, plants cannot be able to carry out the process of photosynthesis, which converts water and carbon dioxide into starch that plants use for food.
Photosynthesis also releases oxygen which is vital for animal life.
