1. What evidence supports the notion that sponges are some of the earliest known multicellular animals?
Serga [27]

<u>Answer:</u> "Chemical fossils"evidence supports the notion that sponges are some of the earliest known multicellular animals.

<u>Explanation:</u>

Sponges are multicellular animals, may belong to Ediacarian period likely to be 80 million years ago or earlier. They catered through a complex system of internal channels, by moving seawater.

Sponges are soft-bodied and very rarely protected as fossils, therefore finding evidence of existence is giant task. The key of their existence came to know from abnormal chemicals which is a steroids of a particular type generated sufficiently by them but virtually never by ordinary organisms.

Analysis of long strata sequence found in Oman and researchers have been able to extract these "chemical fossils" from samples spanning tens of millions of years — before, during and after the Ediacarian period.This gave clear evidence that sponges had to have evolved long before the great variety of multicellular organisms proliferated at the dawn of that time.

s344n2d4d5 [400]

Answer:

<em>The correct option is b)  exponential growth curve</em>

Explanation:

A J-shaped curve can be described as a curve on a graph which represents the phase of exponential growth. During this phase, the population of a certain organism expands rapidly in an exponential manner unless it is stopped due to some factor such as environmental resistance. A J-shaped curve will usually be seen in a new environment when the number of resources is more in the environment to support the growth of the population.
