A specialized protein in saliva breaks up starch molecules in food into smaller chains of simple sugars. In this reaction, specialized protein is the enzyme, starch molecules are the substrate and the product is the smaller chains of simple sugars.
In the field of science, we can describe enzymes are a kind of proteins that lower the activation energy of a reaction, hence speeding up a reaction. In the reaction above, specialized proteins that help in breaking down starch molecules are the enzyme.
Each enzyme has an active site into which only a specific substrate can fit and get catalyzed. In the scenario above, starch molecules are the substrates as they are the ones being catalyzed.
The products are the resulting substances that are produced after catalysis. In the case above, as smaller chains of simple sugars are the ending results, hence they are the products.

Which term best describes the plasma membrane? hypotonic permeable selectively permeable solid
The plasma membrane is selectively permeable. Plasma membrane is also known as cell membrane.
What is Plasma membrane? The plasma membrane is also known as the cell membrane. The primary function of the plasma membrane is to protect the constituents of the cell from the outside environment. They are primarily composed of lipids and proteins that exhibit selective permeability. The plasma membrane is selectively permeable, keeping track of which components enter and exit the cell. The plasma membrane's four primary functions are identification, communication, regulation of solute exchange across the membrane, and isolation of the cytoplasm from the external environment. The plasma membrane is mostly made up of phospholipids, which are made up of fatty acids and alcohol. The phospholipids in the plasma membrane are organized in two layers, known as a phospholipid bilayer, with a hydrophobic (water-hating) interior and a hydrophilic (water-loving) exterior.To learn more abut plasma membrane:

Which example demonstrates metabolism? (brainly wont let me see other answers ;( )
The group of chemical processes in organisms that maintain life is known as metabolism. The three primary functions of metabolism are: converting the energy in food into energy that can be used to power cellular functions.
It is convenient to divide metabolism into two groups: Molecules are broken down during catabolism to provide energy. All of the substances that the cells require are synthesised during anabolism. Metabolic processes include the chemical reactions that keep you alive. One example of metabolism is the rate at which you burn fat and consume calories. the constant anabolic and catabolic chemical and physical processes that occur in living things and their cells.

What would be the resulting 6 base sequence after combining the xhoi-generated sticky end with a sali-generated sticky end? (you can choose more than one correct answer.)
GTGAC would be the resulting 6 base sequence after combining the xhoi generated sticky end with sali generated sticky ends.
How sticky ends produce? Why they are called sticky ends?Restrictions enzymes cause sticky ends to form. Although they cut the DNA strand between the identical two bases on the opposing strands, the restriction enzymes cut the DNA strand somewhat outside of the palindromic sequences' centers. At the ends, single-stranded sections are left. On each strand, there are protruding sections known as "sticky ends."
Due to the hydrogen connections that these sticky ends create with their complementary cut counterparts, they are known as sticky ends. The DNA ligase enzyme's function is made easier by the ends' stickiness.
So, the answer would be GTGAC .

GTC GAC would be the resulting 6 base sequence after combining the Choi-generated sticky end with a sali-generated sticky end.
What are sticky ends?A restriction enzyme may cut DNA at a specified sequence of nucleotides, typically 4, 6, or 8 nucleotides long, and can produce blunt ends with symmetrical cleavage or "sticky" ends with asymmetrical cleavage.
When the restriction enzyme makes a cut between two bases on the same strand at one end of the sequence and then a second cut on the opposite end of the complementary strand, the result is a "sticky" end.
The result will be two ends of DNA with certain nucleotides lacking complementary bases.
A restriction enzyme recognizes palindromic sequences or sequences that are the same whether they are read forward or backward.
Palindromic sequences are sequences that are the same whether they are read forward or backward.

The net primary production of a pine forest on a lava flow on mount fuji is about 175,000kcal/m2/yr, and the plant respiration is estimated to be 115,000kcal/m2/yr. What is the total amount of energy transferred during photosynthesis for this ecosystem?.
The total amount of energy transferred during photosynthesis for this ecosystem equals 260,000 kcal/m2/yr.
In order to respond to this question, we must be aware of Energy gathered and transformed into chemical energy throughout photosynthesis is known as gross primary productivity (GPP). Net primary productivity (NPP) is the product of gross primary output and respiration rate.
Therefore, we must add NPP to the respiration rate in order to determine GPP. If, then
NPP = 165,000 kcal/m2 per year
R = 9.5 kcal/m2/year
NPP equals GPP - respiration
NPP equals GPP - respiration
NPP=GPP-Respiration
Therefore,
NPP + R, therefore GPP.
NPP+R= GPP
GPP is equal to 95,000 kcal/m2/yr plus 165,000 kcal/m2/yr.
GPP = 260 kcal/m2/year

In the ocean around the Arctic shore, pseudoalteromonas haloplanktis grows. It is a chemoautotrophic oxygenic organism. It has a number of cold-resistant enzymes that keep its metabolism going. In general, the greater flexibility at low temperatures results in decreased stability at higher temperatures.
Though widespread, thermolability isn't present in all cold-adapted enzymes. Recently, it was shown that three superoxide dismutases from the Antarctic psychrophilic ciliate Euplotes focardii have melting points between 50 and 70 °C, indicating a mix of cold adaption and relative tolerance to high temperatures.
