Bony fishes are categorized into Actinopterygii, the ray-finned fishes with fin rays supported by bony spines, and Sarcopterygii, the lobe-finned fishes with fleshy lobed fins resembling tetrapod limbs. Both share traits such as a bony skeleton, a lung or swim bladder, a gill cover, and color vision, and belong to the largest class of vertebrates.
Characteristics of Ray-Finned and Lobe-Finned Bony Fishes
The two subclasses of bony fishes, which are Actinopterygii (ray-finned fishes) and Sarcopterygii (lobe-finned fishes), exhibit distinct characteristics. Ray-finned fishes are the most diverse and include species like tuna, bass, trout, and salmon. They are characterized by their fin rays - slender bones that support the fin web which is composed of skin. These fishes have a lung or swim bladder for buoyancy control, an operculum that covers their gills, and can see in color.
In contrast, lobe-finned fishes, which include coelacanths and lungfish, possess fleshy lobed fins with a structure similar to that of tetrapod limbs. These fins are supported by internal bones and have the potential to evolve into legs, as they did in the ancestral lineage that led to amphibians and other terrestrial vertebrates. Lobe-finned fishes also feature enamel-covered teeth and can have both gills and lungs.
Both subclasses fall under the clade Osteichthyes and share characteristics like a bony skeleton, head, and pectoral girdles covered with bones, and jointed, segmented rods supporting the fins. They are categorized under the largest class of vertebrates existing today with a count of approximately 30,000 species.

The term ____________ describes cellular respiration in the absence of ____________ . oxygen is the final electron acceptor in ____________ respiration. the breakdown of organic molecules without oxygen is called ____________ . during fermentation, yeast break down pyruvate into ____________ and acetaldehyde. aerobic respiration produces ____________ molecules whereas anaerobic respiration produces ____________ molecules.
The term anaerobic describes cellular respiration in the absence of oxygen. Oxygen is the final electron acceptor in aerobic respiration.
What is respiration?Respiration is the process of releasing energy from food through oxidation. Aerobic along with anaerobic respiration are the two kinds of respiration.
Aerobic means "with air," and it refers to the body's use of oxygen to produce energy. This usually refers to any exercise that lasts more than two minutes.
Aerobic 'steady state' exercise is performed continuously. Anaerobic refers to the body producing energy without the use of oxygen.
The term anaerobic refers to cellular respiration that occurs in the absence of oxygen. In aerobic respiration, oxygen is the final electron acceptor.
Fermentation is the breakdown of organic molecules in the absence of oxygen. Yeast converts pyruvate to carbon dioxide and acetaldehyde during fermentation.
Aerobic respiration generates 34-38 ATP molecules, whereas anaerobic respiration generates only two.
Thus, these are the complete sentences for the given scenario.

Final answer:
To determine if the glucose-aversion trait becomes more common in a cockroach population as a result of adaptive evolution, you can conduct a study comparing populations that have been exposed to glucose-rich environments with populations that have not.
Explanation:
To determine if the glucose-aversion trait becomes more common in a cockroach population as a result of adaptive evolution, you can conduct a study comparing populations that have been exposed to glucose-rich environments with populations that have not. Here are the steps you can follow:
Collect a sample of cockroaches from different populations.
Separate the cockroaches into two groups, one exposed to a glucose-rich environment and one not exposed to glucose.
Observe the populations over several generations.
Measure the frequency of the glucose-aversion trait in each population.
If the glucose-aversion trait becomes more common in the population exposed to glucose, it suggests that it has been favored by natural selection and has undergone adaptive evolution.
By comparing the populations under different conditions, you can determine if the glucose-aversion trait is becoming more common due to adaptive evolution.

What molecule is responsible for carrying the acetyl group from pyruvate into the citric acid cycle?
Final answer:
Acetyl CoA is the molecule responsible for carrying the acetyl group from pyruvate into the citric acid cycle in cellular respiration. It combines with oxaloacetate to form citrate in the cycle.
Explanation:
The molecule responsible for carrying the acetyl group from pyruvate into the citric acid cycle is acetyl CoA.
During the conversion of pyruvate into the acetyl group, a molecule of carbon dioxide and two high-energy electrons are removed. The carbon dioxide accounts for two of the six carbons of the original glucose molecule, and the electrons are picked up by NAD* to form NADH.
Acetyl CoA then enters the citric acid cycle by combining with a four-carbon molecule, oxaloacetate, to form the six-carbon molecule citrate.

Part a - the cell cycle drag the pink labels onto the pink targets to identify the two main phases of the cell cycle. then drag the blue labels onto the blue targets to identify the key stages that occur during those phases.
The two main stages of the cell cycle are interphase and M phase. Interphase is further segregated into G1, S, and G2 phase while the M phase is segregated into prophase, metaphase, anaphase, and telophase.
Further Explanation:
The cell cycle refers to an ordered flow of events which includes cell growth as well as cellular division. This cycle produces 2 new daughter cells. The cycle starts with interphase; during which, the cell grows and replicates its own DNA or deoxyribonucleic acid. The interphase begins with:
1. G1 phase: This is the primary growth phase provide nutrient to the cell.
2. S phase or synthesis of DNA: During this phase, the replication of DNA takes place. The centrosome is divide and forms mitotic spindle during the mitosis phase.
3. G2 or second gap: during this phase, the cell mainly replenishes its energy stores as well as synthesizes the proteins which are required for the chromosome manipulation.
The second phase of the cell cycle is the mitosis or M phase. Mitotic phase refers to a multiphase process during which the chromosomes are aligned, segregated, and moved into the 2 new daughter cells which are identical to each other.
This phase starts with:
1. Prophase: During this phase, the condensation of the chromosomes takes place and these chromosomes become visible. Spindle fibers formation take place, breakdown of the nuclear envelope, and nucleolus disappear.
2. Metaphase: During this phase, the formation of spindle fibers is completed and centrosomes are found at the opposite terminals of the cell. The chromosomes line up at the metaphase plate. Each of the sister chromatids is linked to the spindle fiber starting from the opposite poles.
3. Anaphase: During this phase, the cohesion proteins link with the sister chromatids and splits them down. The sister chromatids are pulled towards the opposite terminals of the cell and the non-kinetochore spindle fibers mainly lengthen and elongate the cell.
4. Telophase: During this last phase, the chromosomes arrive at the opposite terminals and start to decondense. Nuclear envelope reappears, and mitotic spindle breaks down. This marks the end of the mitosis.
The end phase of the cell cycle is called cytokinesis wherein the cleavage furrow occurs are segregates the daughter cells. In plant cells, the cell plate is responsible for the segregation of the daughter cells.
