This diagram shows three layers of rock.
Layer A (sedimentary)
Segmented worm
Peripatus lived 570
million years ago
Layer B (sedimentary)
No fossils
Layer C (sedimentary)
Trilobite: Shumardia
Lived 498.5-445.6
million years ago
Part A
What is unusual about the arrangement of the fossils in the diagram?

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air

explanation:

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
