In terrestrial ecosystems, primary producers constitute the great biomass, and they are often large such as trees. However, the primary producers in marine ecosystems is a direct contrast to the primary producers in land. The dominant primary producers in the ocean are the phytoplankton which are microscopic. Land primary producers are bigger because biomass is highly conserve like in woody plants. While the marine primary producers are involved in a lot of process either by consumers or reducers. As a result, they are smaller.
Answer:
c. periodic interest payments.
Explanation:
A bond can be defined as a debt or fixed investment security, in which a bondholder (creditor or investor) loans an amount of money to the bond issuer (government or corporations) for a specific period of time.
Generally, a bond issuer is expected to return the principal at maturity with an agreed upon interest to the bondholder, which is payable at fixed intervals.
Coupon bonds also known as bearer bonds can be defined as a debt instrument which typically has a coupon (detachable paper slip) attached to represent the periodic interest payments made semiannually or annually depending on the arrangement.
Basically, the bondholder normally receive these coupons (detachable paper slip) from the bond issuer within the period in which the bond was issued and its maturity.
Hence, coupon bonds are bonds with coupons (detachable paper slip) attached that represent periodic interest payments to be collected by the bondholder.

Answer:
A) two examples of environmental factors that may impact salivary peroxidase activity are pH and temperature. All enzymes have an ideal pH range. When the environment has a pH in that specific range, the enzymatic reaction rate will be the fastest. However, when the environment deviates from the pH range, the enzyme's reaction rate will be slower. Furthermore, when the pH is too far off that ideal pH range, then the salivary peroxidase may denature and unravel, due to it being a protein. Another factor is temperature. When temperature is higher, the reaction rate increases. However, when the temperature is lower, the reaction rate decreases. However, when the temperature gets too high, then the enzyme may denature.
B) The effects of defects in the thiocyanate transport channels would be for lactoperoxidase to not be able to function properly, causing defects in the defense against pathogenic microorganisms in the intestinal tract of newborn infants and defects in sterility of the secretions for the respiratory tract.
In order for lactoperoxidase to function properly, thiocyanate is necessary. Because of this, Therefore, thiocyanate is likely a cofactor, allowing for lactoperoxidase to function.
Because of this, if the thiocyanate transport channels are defective, thiocyanate can likely not reach the lactoperoxidase, and can therefore not bind to it. This defect in the transport channels would mean that thiocyanate cannot carry out its necessary function of activating lactoperoxidase.
