bicarbonate can act as an acid or a base (i.e., donate or accept hydrogen ions) depending on conditions.
Under present-day conditions, these reactions buffer the pH of surface seawater at a slightly basic value of about 8.1 (above the neutral value around 7.0). At this pH, the total dissolved inorganic carbon (DIC ~ 2 mM) consists of approximately 1% CO2, 90% HCO3–, and 9% CO32– (Figure 2.1). The total boric acid concentration (B(OH)4– + B(OH)3)) is about 1/5 that of DIC. As discussed in section 2.2, increases in CO2 will increase the H+concentration, thus decreasing pH; the opposite occurs when CO2 decreases. We note that isotope fractionation between B(OH)3 and B(OH)4–is used for estimating past pH values
Most predators have forward facing eyes, while most prey have side mounted eyes. If you think about the animal behaviors of both prey and predators, you should be able to make connections between their eye placement and their necessities for survival. Most prey have side mounted eyes because it allows for a better depth perception and a wider field of view. This can help the animals keep watch while they graze in open fields. On the other hand, most predators have forward facing eyes because it allows them to focus in on prey while hunting and chasing.
Hope this helps. Good luck! :)
He grew approximately 158 smooth plants. 3 out of 4 are wrinkled, 1 out of 4 is smooth. 1/4 * 633 = 158.25
The event that results from mitosis but not from meiosis is: C) daughter cells that are identical to the parent cell.
Mitosis is the process of cell division where a parent cell divides to form two daughter cells. These cells have the same number of chromosomes as that of their parent and that is the reason why the process is also known by the name equational division.
Meiosis is the process where a cell divided into 4 daughter cells and they have half of the total number of chromosomes as that of their parent. Thus is why the process is also called reductional division. Meiosis does not occur in the somatic cells of the body but in the germ cells.

Answer:
A callus is a hardening of skin, keratin is the protein which is abundant in callus. Skin is a protective layer against a external environment. Outer layer of skin consist of keratin which is also found in hair. Callus is the accumulation of dead cells result due to friction and pressure exerts on the part in which they are present. The keratin component (keratinocytes) remains undifferentiated in these dead cells which causes hardening in callus.
