Answer:
Microbial mats.
Explanation:
Microbes formed sheets that were able to capture layers of sediment is called microbial mats. These mats of microbes provide good fossil evidence to the researchers. These microbial mats consist of bacteria and archaea which is considered the earliest form of life on earth. These microbial mats grow on moist places as compared to dry environment. About 3,500 million years ago, these microbes are the most important members of earth and maintainers of the ecosystems.
Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life
Explanation:
Answer:
D
Explanation:
When a population is genetically diverse there is a higher probability for some individuals in that population to survive during harsh conditions such as drought due to their highly resistant genes.
Answer:
b) inhibits, activates
Explanation:
During the rhythmic ativity of sleep, thalamocortical neuron activity inhibits neuron activity, that in turn, activates thalamocortical activity.
Answer: C. The red blood cells released water through osmosis. The release of water helped the blood cells keep a similar concentration of solutes as the outside solution.
Explanation:
Osmosis is a process whereby water molecules move from an area where they are in higher concentration than a solute to an area where they are in lower concentration. They do this by moving through a selectively-permeable membrane.
With sugar added to the solution, the water in the red blood cells will have a higher concentration of water in the cells than the solution so water molecules will move from the cell - through the cell membrane - to the solution. They will keep doing so till the concentration of solutes are more or less similar in both the cells and the solution.
