Answer: B, planting mangrove forests
Explanation:
Healthy mangrove forests provide homes for roosting bird species, protect coastal communities from storm surges, and provide a nursery habitat for juvenile coral reef organisms.
A is incorrect because the construction of a seawall would prevent the threat of storm surge but would not provide a habitat for roosting bird species nor help the health of the coral reef.
C is incorrect because the construction of an offshore breakwater would prevent the threat of storm surge but would not provide a habitat for roosting bird species. Its construction would also likely damage the nearby coral reef.
D is incorrect because creating large sand dunes could initially protect from storm surges, but this can also cause erosion. Sand dunes would not provide habitat for roosting bird species nor would they help to protect the health of the coral reef.
Answer:
It means that the cyanogen bromide hydrolyzes methionine residues with high efficiency, while trypsin is an enzyme that cuts proteins at lysine and arginine peptidic bonds, thereby producing 4 and 15 polypeptides, respectively.
Explanation:
Cyanogen bromide is a pseudohalogen compound that is used to cut the C-terminus of the methionine residues. On the other hand, the trypsin is an enzyme produced by the pancreas as trypsinogen that is used by the digestive system (intestine) to digest polypeptides.
Answer:
The correct answer is D. Umbilical cord
Explanation:
The umbilical cord connects the fetus to the placenta and through it exchanges nutritional substances as well as oxygen-rich blood. The umbilical cord is maintained throughout gestation until the moment of birth, when it is cut and leaves a permanent scar, the navel. The umbilical cord is responsible for breathing and feeding the fetus until the moment it is born, so any failure or blockage in the circulation of oxygen and nutrients through the cord can lead to injury or even death of the embryo. It also serves to remove waste and carbon dioxide (CO2).
Answer:
The difference is that in plant cells, there are vacuoles, a cell wall, and chloroplasts. All 3 of those are only found in plant cells.
