What modification is necessary for a successful gas exchange, one example?Alveoli modifications:
Moisture-filled walls: Gases dissolve in the moisture, which makes it easier for them to cross the gas exchange surface. Gases can travel through permeable walls. large blood supply, ensuring that blood rich in carbon dioxide is transported to the lungs and blood rich in oxygen is removed from the lungs.
Compare the Australian Fitzroy River turtle's gas exchange system to that of fish.Gills are found in fish, while specialized excretory openings are seen in turtles. These gaseous exchange systems have a huge surface area, a plentiful blood supply, and are ventilated by water movement for a sharp gradient in concentration. The main distinction is where the gas exchange surface is located.

What are the similarities between extinct species endangered species
describe in general terms the intermediate species that led to the modern panda
Answer:
The intermediate species that led to the modern panda were likely carnivorous mammals that gradually evolved to have a diet that was primarily herbivorous. This evolution likely occurred over a period of millions of years and involved the development of physical adaptations such as enlarged molars and a strong jaw to help with grinding and crushing plant material. The intermediate species may also have evolved to have a more specialized digestive system to better process plant matter, as well as physical features such as a rounder head and short limbs to help with climbing and foraging in trees.
It is not known exactly what the intermediate species looked like or how many there were, but it is likely that they were small, agile mammals that lived in forests and other wooded areas. They may have had some physical similarities to modern pandas, such as a black and white coloration, but they would have differed in other ways, such as in their size, shape, and behavior.
Overall, the intermediate species that led to the modern panda were likely a diverse group of animals that evolved over time to become specialized herbivores with a unique set of physical and behavioral adaptations.

What is an example of an advantageous trait? (1 point)
O Elephants are being born without tusks, in response to pressures from poaching for ivory.
Peacocks are brightly colored to attract mates, though their feathers make them more susceptible to
predation.
O Black bears are not always black, but come in various shades including blonde, cinnamon, and brown
A large proportion of Ireland's population has red hair, more than anywhere else in the world.
Answer:
The correct answer is a) Elephants are being born without tusks, in response to pressures from poaching for ivory.
Explanation:
Individuals with advantageous traits are more likely than others of their species to survive and reproduce. This is why the elephants would be the answer, as opposed to the peacocks. The brightly colored peacock feathers make them more susceptible to predation, which would actually decrease their chance for survival.
An example of an advantageous trait is the Elephants are being born without tusks, in response to pressures from poaching for ivory.
What are adaptive characteristics of animals?All characteristics that suit their possessors to something are generally said to be adaptive and allow living beings to develop a certain harmony with the environment, thus adjusting themselves for their survival in a given place.

Which conditions suggest that a bond will be ionic?
Answer:
A and C
Explanation:
Ionic bond is between a metal and a nonmetal
The rule is that when the electronegativity difference is greater than 2.0, the bond is considered ionic.
Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.

Stainings is a reagent or dye used to stain microscope specimens so as to make some structures visible.
Peptidogycan is a derivative polymer of glycan and peptides found in bacterial cell walls and varies in compositional concentration from species to species.
Cell wall- A thick, fairly rigid, layer formed around individual cells of bacteria, Archaea, fungi, plants, and algae (but not animals and other protists which generally have cell membranes without cell walls). The cell wall is external to the cell membrane and serves a structural function helping the cell maintain its shape and protecting the cell from damage.
There different types of staining techniques and classification based on the aim of the experiment and here is a few;
The etymology is from Gram + positive, is named after Dan ish bacteriologist Hans Christian Gram, who invented the Gram staining technique.
Used in bacteriology , bacteria that stains dark blue or violet after Gram staining, due to large quantities of peptidoglycan in the cell wall are gram positive.
And gram-negative bacteria is one that is not stained violet by Gram's method.
A spore is thick resistant particle produced by a bacterium or protist to survive in harsh or unfavorable conditions.

Answer:

There are two principal types of cells in the organism: Somatic diploid cells (2n) that reproduce by the process of mitosis, and germ cells that are diploid reproductive cells in charge of gamete production. Germ cells divide by mitosis and meiosis. Through the process of mitosis, they originate more sexual cells, but through the process of meiosis, they give place to haploid gametes, called sperm and egg cells, through the gametogenesis process.
Both somatic cells and germinal cells will end their cycle becoming two daughter cells with the same genetic dotation. Mitosis produces two daughter diploid cells (2n) from a diploid somatic cell (2n). During mitosis, the whole cell (23 chromosomes) first duplicates producing 46 chromosomes. Then the duplicated cell separates, producing two equal cells carrying 23 chromosomes each.
When we talk about the cell cycle, we refer to the interphase and the cell division (mitosis or meiosis).
The interphase occurs before mitosis and involves 90% of the cell cycle. The interphase is conformed of the G1, S, and G2 stages.
• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures also double. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi complex and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
• During the S stage, the DNI replication process occurs. This is the only stage in which the DNI molecule replicates. The synthesis of histones and other associated proteins also occurs.
• G2 stage is the interphase last step. DNI molecule begins to slowly condensate. The centrioles duplication process completes. The spindle fibers get assembled.
Once the whole interphase is completed, mitosis occurs involving 10% of the cell cycle.
During mitosis, the original cell with duplicated material suffers division, originating two exact same daughter cells. Mitosis occurs in only one phase.
In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, fibers of the spindle drive chromosomes and take them to the cell equatorial plane, where they line up. Each chromatid joins with a microtubule of opposites poles, but sister chromatids are still together.In the Anaphase, enzymes are activated to break the bonds and separate the chromatids, which migrate to the opposite poles, helped by the single apparatus fibers.In telophase, the duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.give an example of the symbiotic relationship between plants and microorganisms
