Answer:
Chlorophyll
Explanation:
because they lack roots, stems, and leaves.
A. FAMILY, GENUS, SPECIES, SUBSPECIES.
The complete and correct hierarchy of taxonomic groups from largest to smallest are:
1) Domain
1.1) Archaea 1.2) Bactera 1.3) Eukarya
2) Kingdom
2.1) Animalia 2.2) Plantae 2.3) Fungi 2.4) Protista 2.5) Archaea 2.6) Bacteria
3) Phylum - has 35 phyla
4) Class
5) Order
6) Family
7) Genus
8) Species
Fossils only form if certain qualifications are met, and some organisms cannot meet them, so they just cease to exist, not a single sign of them. This could happen if they were organisms that decayed completely. Fossilization can include freezing, drying, and encasement, usually in tar or resin.
Answer:
(a) number of strands (n) = time (t) ÷ proportionality constant (k)
(b) The time needed for the bacterial to double its initial size is 3.36 hours.
Explanation:
(a) Let the rate (time) be represented by t and the amount (number) of strands of bacteria be represented by n
t is proportional to n, therefore, t = kn (k is the proportionality constant)
Since t = kn, then, n = t/k
(b) Initial amount of strands = 300
Amount of strands after 2 hours = 300 + (300 × 20/100) = 300 + 60 = 360
k = t/n = 2/360 = 0.0056 hour/strand
Double of the initial size is 600 (300×2 = 600)
Time (t) needed for the bacterial to double its initial size = kn = 0.0056×600 = 3.36 hours
