The phylum Arthropoda contains a wide diversity of animals with hard exoskeletons and jointed appendages. Many familiar species belong to the phylum Arthropoda—insects, spiders, scorpions, centipedes, and millipedes on land; crabs, crayfish, shrimp, lobsters, and barnacles in water (Fig. 3.72).
Answer:
Where they can survive
Explanation:
Organisms in the domain archaea can survive in extreme environments, such as in hydrothermal vents. Organisms in the domain eukarya, however, cannot. hope this helps!
Answer:
a. histones. is the correct answer.
Explanation:
In a nucleosome, the DNA is wrapped around eight histones proteins to create strong loops termed nucleosome.
A nucleosome is the structural subunit of the chromatin.
Chromatin is a fiber polymer of double-stranded DNA which is composed up of a nucleosome core. The nucleosome core is made of histone proteins
Each nucleosome is composed of DNA enclosed around eight histone proteins which are called histone octamer.
<span>What is the difference between fragmentation and regeneration ?
</span><span>-Fragmentation</span> is when an organism is split into fragments, and each fragment grows into complete, individual organisms that are clones of the original organism.
-Regeneration is the process of regrowth that organisms that allows for partial or complete regrowth of tissue after a damaging event.
The difference is that fragmentation specifies two parts each growing into complete organisms, but regeneration is simply a general process of regrowth. Few species are capable of fragmentation, but ALL species undergo regeneration, to varying degrees
