Speciation is the
process by which new and distinct species are formed. One of the most important
factors necessary for speciation to occur is the genetic isolation of two
populations. This genetic isolation can, over long periods of time, cause these
two groups to become genetically incompatible. Factors that can lead to this
genetic isolation include geographic separation and hostility among population
groups.
Electrons are found outside the nucleus.
Answer: a. dead organisms from the marine food web.
c. liberation through ATP hydrolysis in living organisms.
Upwelling is a wind driven motion of lower bottom nutrient rich and warmer water on the surface of the water body. This wind driven motion facilitates the movement of nutrients available for growth of primary producers like phytoplanktons growing on the surface of water body. The dead organisms from the marine food web get decomposed and the organic matter obtain after decomposition is a rich source of phosphorous. This phosphorous gets transferred to the upper layers of the water body by upwelling. In aquatic organisms ATP hydrolysis occurs which is a catabolic process that uses water to split the bonds present in the ATP molecule and hence, releases energy for functions performed by them along with a release in phosphate atom. This phosphate gets mixed with the water. Therefore, PO32 come from dead organisms from the marine food web and liberation through ATP hydrolysis in living organisms that circulates due to upwelling.
Eukaryotic cells can assemble into multi-cellular organisms. A.
Answer:
B.
Explanation:
Which of the following describes the outer core?
A. The solid, rocky layer on the outside
B. A layer of liquid metal that spins
C. A dense layer of solid metal
D. Hot, partially melted rock that flows
Because the outer core is the third layer of the Earth. It is the only liquid layer, of metals irons and nickel Also its responsible for Earths magnetic field as earth spins on its Axis the substances move also move around during that
