When a geologist working in stratified rocks observes a limestone bed with oyster fossils overlain by beds with clam and echinoderm fossils indicative of marine conditions, the fossils probably indicate ----- that the environment had changed as the sea level rose and it displaced the oysters environment with marine conditions represented by the clams and echinoderms.
All biomolecules could be called carbon-based molecules.
The monomers of DNA are nucleotides.
Cell membranes are made, in part, from phospholipids.
The monomers of of starch are monosaccharides.
Explanation:
Biological macromolecules are giant carbon-based molecules. They are polymers made by complex condensation reactions linking them together.
These molecules are typically produced exclusively by living organisms and this is why they are called biological macromolecules.
They are usually classified as organic compounds for their linkage to living processes.
- It is correct that all biomolecules are carbon-based molecules. They are primarily made up of carbon, hydrogen and oxygen with some other elements.
- Deoxyribo-nuclei Acids are macromolecules that contains all information about the life of an organism. The DNA is located in the nucleus of cells and it is the genetic matter that controls life activities. The basic unit of DNA is the nucleotides.
- Cell membranes are structural component of cells that helps to regulate the movement of materials in and out of the cell. They are made up of phospholipids.
- Monomers of starch are monosaccharides. These are the simplest unit of starch that cannot be further hydrolyzed. They are usually called simple sugars. Examples are glucose and fructose.

First, we want to know the average length of each cell. If you have 100 cells in a 1 millimeter space, we would do 1 ÷ 100. 1 ÷ 100 = 0.01 millimeters. Hope this helped!
It is because they lose body temperature
Answer:
It's d , activity level
Explanation:
Tempratement is something you are born with and it defines how an individual respond to the world
While activity level is the amount of motion that a child performs while doing some physical activity
They start in utero when the baby moves and kicks inside
When they grown up ,some children possess more energy and they don't seem to stay at one place
When they grow up they will jump and run a lot ,those who are highly active
