Explanation:

Breathe via the gills. Fish with bones and fish with cartilage both have jaws in their mouths.

Chondrichthyes:

The second category of fish is the Class Chondrichthyes, which contains sharks, rays, and chimaeras. Sharks are among the oldest fish species to have a jaw. Their upper and lower jaws are made of cartilage. A shark can grow teeth indefinitely, but neither you nor I can have more than two sets. Because they regularly replace lost or damaged teeth with brand-new ones, sharks never run out of teeth.

Osteichthyes:

The Osteichthyes, or true bony fish, are the third major category of fish and are further classified into two divisions. The first class, known as the Sarcopterygii, is the more ape-like of the two classes. This class includes all terrestrial vertebrates, including cows and humans, as well as fish like coelacanths and lungfish.

Answer:

When an individual develops the traits

Explanation:

the second option is wrong because evolution isn't an immediate change but takes thousands to millions of years depending on what is evolving.

The third option is close but the difference is natural selection is when weaker animals of a species die out while the stronger ones survive for example, when one bird hatches before the other the hatched bird may push the egg out of the nest to get more food. That is an example of natural selection. It is a part of evolution but not evolution itself.

DNA replication relies on the ___complementarity___ of DNA strands according to the ___AT/GC___ rule.

DNA replication is the process by which genomic DNA is copied into cells. Before a cell can divide, it must first copy (or replicate) its entire genome so that each resulting daughter cell has its own complete genome. This is a semi-conservative process, meaning that each new copy of DNA contains one parent strand and one new strand of the original DNA. Replication is an essential process because each time a cell divides, the two new daughter cells must contain the same genetic information or DNA as the parent cell. It is found in the nucleus of eukaryotic cells and the nucleoid region of prokaryotic cells. DNA replication occurs in the S phase of the cell cycle before cell division

The principle of complementarity governs both transcription and DNA replication due to the fact that when two DNA or RNA sequences are arranged antiparallel to each other, the nucleotide bases at each position in the sequences are complementary or mirror images.

In Crossing-over, a part of the chromosome will be exchanged with another part in phenotype.

Crossover provides for the exchange of DNA sequences between homologous chromosomes during meiosis. This process forms a new arrangement of the genetic information stored on the maternal and paternal chromosomes. New combinations of genes residing on the same chromosome increase the genetic diversity of offspring, making them different from their parents.

For example, one chromosome contains two mutated genes of hers that affect a particular trait in an organism. Without crossbreeding, both mutated genes are passed on to offspring. However, the process of crossover can segregate genes between two homologous chromosomes. Since only one of the homologous chromosomes is inherited from one parent, the odds of inheriting both mutated genes are reduced and the offspring will have only one mutated gene of hers.

The advantage of the first model is it used less space for showing stages of mitosis whereas the disadvantage of using this model in Mitosis is that it does not provide detailed information.  

Mitosis is a process of cell division in cells that occurs when a parent cell divides to form two identical daughter cells. During this cell division, diploid daughter cells are produced from a single parent cell while on the other hand, meiosis is a process of cell division in cells that happens when a parent cell divides to form four identical daughter cells. Meiosis refers to the formation of four cells from a single parent having haploid chromosomes. The advantage of the first model is that it provides stages of mitosis by using less space whereas the disadvantage of using this model Mitosis is that it does not provide detailed information. The advantage of the second model is that it does not provide detailed information whereas the disadvantage of using this model of Mitosis is that it provides stages of mitosis by using less space.

2 ATPs are generated from glucose 6-phosphate during the glycolytic pathway.

The glycolysis pathway, which is a series of enzyme-mediated steps, is used to metabolize G6-P in the cytoplasm of the cell. The first step of glycolysis is the isomerization of glucose-6-phosphate (G6P) into fructose-6-phosphate, which creates triose-phosphate and two pyruvate molecules as well as a small amount of ATP (net gain of 2 ATP molecules). The majority of ATP is then produced by the aerobic oxidation of pyruvate in differentiated cells. Although glucose is frequently regarded as the primary energy source for cells, it is actually primarily a major supply of carbon skeletons for cell growth and survival.
