Answer:

Older fossils are found in deeper layers of sedimentary rock.

Explanation:

The relationship between undisturbed sedimentary rock layers and fossils is that older fossils are found in deeper layers of sedimentary rocks.

This is one of the premise of the law of superposition and principle of fossil and fauna succession.

  • An undisturbed sequence is one in which the sedimentary layers have been arranged sequentially.
  • The oldest is at the bottom and the youngest on top.
  • Also, fossils grade in this manner too.
  • The oldest fossils will be in the oldest bed which is the deepest layer.
  • The youngest bed will contain the youngest fossils in like manner too.

Lady bird [3.3K]

Answer:

The offspring with large, deeply colored flowers is produced from vegetative reproduction which the offspring with small, lightly colored flowers is produced from sexual reproduction.

Explanation:

Reproduction of a plant is the propagation of that plant and it occurs via the sexual or asexual means. The asexual means also called vegetative reproduction involves only one parents and the resulting offspring grows from a part of this parent. Sexual reproduction involves the union of sex cells from two parents (male and female).

In asexual or vegetative reproduction, the offsprings are genetically identical to the parent they emanate from while in sexual reproduction, the offsprings can be genetically different due to the process of recombination that occurs in gametes during their formation (meiosis). This allows for genetic variation among the offsprings.

Therefore, the offspring that resembles the parent i.e. large and deeply colored was likely produced by the vegetative or asexual means of reproduction while the offspring that exhibited a different characteristics from the parent was produced from sexual reproduction.
