Answer:
The rate of a reaction is the speed at which a chemical reaction happens. If a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a high rate.
Answer:The typical tsunami frequency band ranges from about 0.14 to 8 mHz.
Explanation: The frequency of the earthquake-induced tsunami is controlled by the earthquake rupture, the earthquake depth, and the depth of water above the seafloor displacement.
Answer: Elephants form deep family bonds and live in tight matriarchal family groups of related females called a herd. The herd is led by the oldest and often largest female in the herd, called a matriarch. They live in herds so that the young elephants stay safe from predators.
That's what I got, I hope it helped
During cellular respiration, the bonds of food molecules are broken to energy can be released to fuel other cellular processes. In order for this to occur, new compounds with lower-energy bonds must be formed when high-energy bonds in food molecules are broken.
This is due to the Law of Conservation of Energy.
Answer:
Plant tissues have several types of cells i.e vessel elements and tracheids (in xylem),sieve tube cells and companion cells (in phloem) ,parenchyma cells,collenchyma cells and sclerenchyma cells.
Explanation:
Xylem is made up of vessel elememts and tracheids.
Vessel elements have thick secondary cell walls.They lack end walls and join together to form long tubes.
Tracheids are slender cells with overlapping ends.
Phloem is made up of sieve tube cells and companion cells.
Sieve tube cells are long and their end walls have small pores.
Companion cells make proteins for sieve tube cells.
Parenchyma cells are spherical but flat at point of contact.They have thin primary cell walls and have large vacuole for storage of food.In leaves they are called mesophyll cells and are the sites for photosynthesis.In other parts they are sites of respiration and protein synthesis.
Collenchyma cells are fexible and function to support the organs in which they are found.
Sclerenchyma cells contain rigid secondary cell walls.Their cell walls are hardened with lignin which is the main chemical component of wood.
