Answer:
(<u>Bone deposition</u>),
<u>(Bone resorption</u><u>)</u>,
<u>Remodeling</u>
<u>Periosteal</u><u> </u>,
<u>Nedosteal,</u>
<u>The compact bone, </u>
<u> Spongy bone.</u>
Explanation:
The constant, dynamic process of continual addition of new bone tissue (<u>bone deposition</u>) and removal of old bone tissue (<u>bone resorption</u>) is a process called bone <u>remodeling</u>. This ongoing process occurs at both the <u>periosteal</u> (outer) and<u> nedosteal </u>(inner) surfaces of a bone.
It is estimated that about <u>nedosteal</u> of the adult human skeleton is replaced yearly. This process does not occur at the same rate everywhere in the skeleton. For example,<u> the compact bone</u> in our skeleton is replaced at a slower rate than the <u>spongy bone.</u>

3,2,1,4
Explanation:
as time goes on the water levels rise it expands the bay of the river
Answer:
All of the above are true
Explanation:
Organisms possess two types of genome viz; prokaryotic genome and eukaryotic genome. The eukaryotic genome is possessed by cells with a well-defined nucleus, where their genetic material (DNA). The prokaryotic genome, on the other hand, lacks a membrane-bound nucleus. The major organization or content between these two genomes are:
- Prokaryotic genomes generally have less DNA and fewer genes than eukaryotic genomes.
- Prokaryotic genomes have fewer repeated sequences and noncoding, intragenic sequences than eukaryotic genomes.
- Most prokaryotic genomes are contained in one circular chromosome while most eukaryotic genomes are contained on several linear chromosomes.
- In general, eukaryotic genomes contain many introns, repeated sequences, and transposable elements.
Based on this, all of the above options are TRUE
Answer:
have curved protofilaments at their plus ends
Explanation:
Microtubules are polymers of tubulin proteins that function as the cytoskeleton of eukaryotic cells. Microtubules are dynamic structures that can grow and shrink at a rapid rate. During this process, tubulin subunits can associate and dissociate at the plus end of the protofilament. Tubulin subunits bind to two GTP molecules, one of which is hydrolyzed to GDP after assembly. When microtubules are unstable, protofilaments curl outwards because GDP-bound tubulin has a weak affinity (thereby curving it) and disassemble. The dynamic stability of microtubules is regulated by a feedback loop: when microtubules shrink, free tubulin concentration increases and microtubules start to grow. As microtubules grow, free tubulin concentration decreases and the rate of GTP-tubulin addition also decreases.
