Your answer would be The microorganism was unicellular and had a well-defined nucleus.
Answer:
is the evolution of mean fitness an answer
Explanation:
Answer:
In roots, the vascular tissues, i.e., xylem and phloem, are found in the central vascular cylinder, while in stems these tissues are dispersed throughout the stem, generally arranged as a ring towards the outside of the stem (epidermis)
Explanation:
Vascular plants have two different transport tissues: xylem and phloem. The xylem transports water from roots to stems and leaves, while the phloem transports food (i.e. dissolved sugars) from the leaves to all parts of the plant. In roots, vascular tissues form a central core in order to withstand stretching forces. Moreover, in stems, vascular tissues are dispersed (generally concentrated towards the epidermis), in an arrangement that enables them to resist compression and bending forces.
Sources emit greenhouse gases.
Global temperature rises.
Snow and ice.
Sea level rises.
Climate change is the critical alteration in the measures of
climate, such as temperature, rainfall, or wind lasting for an drawn-out
period. It can result from factors more
recently from human exercises through greenhouse gas emissions. The
"greenhouse effect" changes the composition of the atmosphere and traps
heat increasing the global average temperatures. Snow and ice, which helps
regulate the Earth's surface temperature, melts and fills reservoirs and other
bodies of water, causing a rise in sea level.
