Because they don't have a or any cells and have no DNA
Answer:
Biosphere
Explanation:
The atoms make the smallest level of organization. Various atoms together make different types of molecules. Cells are the structural unit of life. Starting from the cell, the various level of organization in increasing order are cell-tissue-organs-organ systems-organisms-populations-community-ecosystem-biosphere. Hence, the biosphere is the largest unit of organization for living beings. Being the highest level of organization, it is most inclusive in nature and includes all other levels
Answer:
In both cases, the gravitational pull of the sun is 'added' to the gravitational pull of the moon on Earth, causing the oceans to bulge a bit more than usual. This means that high tides are higher and low tides are lower than average. These are called 'spring tides.
Explanation:
The aerodynamic shape and lightness of the blue shark body allow it
to move “elegantly” across the oceans. It exhibits countershading like
many other sharks. The upper part is an indigo blue tone while the
ventral and the sides are white.
It has a long caudal heterocercal fin. The second dorsal fin measures
almost half the size of the first and its pectoral fins are unusually
long compared to other sharks. Its eyes are large, its teeth are
triangular, and it has a conical snout.
It reaches a length ranging from 3.8 to 4 meters and weighs about 240
kilograms. This species presents slight sexual dimorphism since the
female tends to measure little more than 1 meter in comparison with the
male.
