What does the principle of faunal succession state

2 answers:

7 0

The principle of faunal succession states that fossil, animal and plant groups occur in the geological record according to an invariable and determined order, so that, if this order is known, it is possible to determine the relative age of the layers from their fossiliferous content. That is, according to this principle, fossil is equal to time. This principle was initially used as a practical instrument, but years later was explained by Darwin's theory of evolution: Since there is an irreversible biological evolution across geological time, fossils must be ordered in time on an evolutionary scale.

The principle of faunal succession, also known as the law of faunal succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna, and that these fossils succeed each other vertically in a specific, reliable order that can be identified over wide horizontal distances.

Answer:

D. Supporting

Explanation:

Ecosystem services include provisioning, regulating, culture and supporting services.

Opening of a mineral mine along a small mountain range will affect the supporting services of ecosystem because supporting services deals with soil formation, provision of habitat and nutrition cycle.

Opening of mineral mine will destroy the tosoil, landscape, forests and wildlife of mountain area which affect the supporting services such as habitat and soil formation.

Which letter in Figure 1 represents meiosis? Why?

SSSSS [86.1K]

The letter D in Figure 1 represents meiosis, while letter A represents mitosis. Meiosis is a reductional cell division.

Mitosis is a type of cell division where a parent cell divides to produce two genetically identical daughter cells (in this case, diploid cells).

Meiosis is a reductional cell division where a parent cell divides twice to produce four daughter cells having half of the genetic material.

Meiosis occurs in germinal cells, while mitosis occurs in somatic (body) cells.

Which of the following best describes how the size and shape of a cell affect its ability to obtain nutrients from its surroundi

fredd [130]

Answer:

A smaller cell has fewer organelles dependent upon nutrient uptake and will acquire them more quickly.

Explanation:

the larger the cell the more distance matter must travel within the cell. if the cell was larger there would be a waste of space in the cell and it would take longer for proteins and enzymes to travel about the cell.
