.......is secreted into the bloodstream, whereas _____ is secreted into mucus such as gastrointestinal fluid, colostrum, saliva, tears, and sweat:
a. Monomeric IgM; pentameris IgM
b. Monomeric IgA; dimeric IgA
c. Monomeric IgA; dimeric IgM
d. Dimeric IgA; monomeric IgA
Answer:
b. Monomeric IgA; dimeric IgA
Explanation:
IgA is a class of antibodies that are found mainly in body secretions. In sweat, tears, saliva, mucus, breast milk, and gastrointestinal secretions, IgA is secreted as a monomeric antibody. Smaller quantities of this class of antibodies are also present in blood and lymph. However, IgA is present in a dimeric form in the bloodstream. It makes up 10–15% of all antibodies in the blood. The main function of this class of antibodies is to give localized protection of mucous membranes against bacteria and viruses.
The overall general process is called diffusion but since the substance specifically mentioned here is water, it will be osmosis.
Clams are adapted for burrowing in the mud and sand by having a short siphon (tube that intakes water) that allows them to expel mud and sand from their gils. They also have adapted by using their foot to dig down into the sand. The foot pushes down through the media and then the clam can pull it self down to the tip of their foot.

Answer:
The basic processes of cellular respiration are: glycolysis, followed by Krebs cycle, the electron transport chain and chemiosmosis.
Explanation:
This task asks one to arrange the basic processes of cellular respiration in the correct order.
Place the major steps of cellular respiration in order by dragging the appropriate figure to each box.
Cellular Activity 1. Glycolysis pathway- The reaction starts with glucose. In the process, glucose is oxidized and split into two 3-carbon compounds. The byproducts is 2 ATP, 2 NADH, and 2 molecules ofpyruvate.
Cellular Activity 2. Krebs cycle- The Krebs cycle follows glycolysis, its an aerobic process but before the glycolysis end-product enters the Krebs cycle, it must first undergo loss of CO2, oxidation, and attachment to coenzyme A to form acetyl CoA.
Cellular Activity 3. Electron transport chain and chemiosmosis pathway- Here we observe that electron carriers such as NADH and FADH2 that are carrying electrons are removed during oxidation steps gets to the electron transport chain and loss their electrons to the chain.
As electrons move along the chain, the energy they lose as they are sequentially made accessible to lower-level electron carriers and electrons eventually to the final electron acceptor is clipped for ATP production.
