Answer
A thick grouping of nerves that run down the back of the embryo
Explanation
The dorsal nerve cord is special embryonic characteristic of the ganglia. It is a hollow dorsal cord that is composed of a section of the exfoliated coagulant that forms a hollow tube unlike solid abdominal tubes in other animal species. It is located in the vertebrae of vertebrates.
Answer:
They are both used for energy
Answer:
The correct answer will be- formation of membrane
Explanation:
The three-stage origin of life theory suggests that life on Earth originated in three phases which are:
1. Phase I: The larger molecules formation began during this unsuitable earthly conditions full of volcanic eruptions and harmful gases underwater.
2. Phase II: The self-replicating molecule begins to form during this phase which contained the coding of life. The self-replicating molecule is known as the formation of the membrane.
3.Phase III: The formation of the membrane which help separate the outer environment from the inner environment was observed during this phase.
Thus, the formation of a membrane is the correct answer.
Answer:DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes.
Explanation: Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions.
The right option is; d. Runoff describes water movement and infiltration describes water storage.
Runoff is the portion of precipitation, irrigation or snow melt that flows over land as surface water instead of infiltrating or evaporating. Factors that influence runoff are permeability, amount of rainfall, slope and vegetation.
Infiltration is the process by which water or precipitation on the ground surface moves into the soil. Factors that determine the rate of infiltration include; soil type, topography of the land, amount of precipitation, vegetation, and pre-saturation levels.
