Marine iguanas feed on seaweed. Seaweed contains starch Starch is digested by enzymes in the digestive system. Explain why the shape of an enzyme is important for digestion.

Answer: The enzyme is a catalyst that speed up the rate of the reaction.

Explanation:

The enzyme can be defined as the protein that is involved in the catalytic activity of the reaction. The shape of the enzyme is important as it determines to which substrate it binds to. The enzyme is specific to the substrate and binds to a specific kind of substrate. During the digestion process the enzyme binds to the specific substrate like protein, carbohydrates, fats, and other biomolecules present in the food to simplify the digestion process. Starch is digested into maltose by the enzyme salivary amylase in the mouth.

Suppose an individual giraffe could not reach high leaves on a tree
its neck was too short. Lamarck's theory would suggest that the giraffe could
undergo physical changes that would lengthen its neck simply by stretching
to reach the branches. What experimental result would disprove this?
E The necks of giraffes today are shorter than the necks of early giraffes.
G. Giraffes with longer necks prefer to eat leaves from higher branches.
H. Neck lengtı does not change when giraffes are fed branches at different
heights.
1. Giraffes with longer necks frequently produce offspring that also have
longer necks.

Match the causes with their effects.
Cause: Convection currents cycle through magma.
Cause: Unstable isotopes inside Earth release energy.
Cause: Iron in Earth’s outer core swirls due to convection currents.
Effect: Radiogenic heat is released.

Read the passage. Then explain the ways humans have influenced the traits in corn plants and the impacts each biotechnology has had.

Passage
Many of the types of corn found in grocery stores were originally bred for their taste and productivity. But these varieties are often threatened by pests. This makes it harder for farmers to produce enough corn.
Scientists have used genetic engineering to make GMO corn plants that are resistant to pests. In one type of GMO plant, they added genes from bacteria that live in soil. The genes let the GMO plants produce a bacterial protein that kills certain insects.
