Answer:
What is the difference between microevolution and macroevolution? Microevolution deals with changes in the gene pool of a single population. Macroevolution considers the broad pattern of evolutionary change over long periods of time and includes the origin of new groups.
Answer:
The correct answer is - 2) density-independent limiting factor.
Explanation:
Density-independent limiting factors are the factors that cause a change in the size of the population without getting influenced by the density of the population.
Density-independent limiting factors include biotic or abiotic factors with catastrophic conditions such as natural disasters such as floods, earthquakes, drought, fires, and many more.
Drought affects the size of the population by increasing competition in the ecosystem for resources.
Gram positive bacteria have cell walls composed of thick layers of peptidoglycan.
Answer: Almost all the ocean will be in danger
Explanation: Species of fish, whale, squid, and all sorts of animals eat krill! If Krill were to "Vanish", then the bigger creatures that fed upon it would start to vanish also, such as whales and squid
many sea creatures feed upon fish right? if they were gone because of krills non-existants, half of the oceans creatures will be in danger
:D
The answer to your question is C- colder , saltier , and denser why because they don't have the same density level and deep ocean water is more dense than surface. and also From
your feet to your knees the water feels icy cold and from your knees to your head the water feels
warm. You probably wondered what causes this to happen. What you felt were warm surface
currents and cold deep currents. Changes in the density set these currents in motion. some ocean currents are set in motion by the wind other ocean currents are created by something you can't feel or see. Differences in density of water can also cause currents to form and move. Density is affected by temperature and salinity. i hoped i helped
