True
False
Answer:
False
Explanation:
Tsunamis are massive waves, and tidal waves are just, well, waves! Like the ones we see when we go to the beach.
Answer:
False
Explanation:
A tidal wave is a shallow water wave caused by the gravitational interactions between the Sun, Moon, and Earth
tsunami is an ocean wave triggered by large earthquakes that occur near or under the ocean, volcanic eruptions, submarine landslides, or by onshore landslides in which large volumes of debris fall into the water.

none of the above
Answer:
The correct answer is - None of the above.

Why is the ovum so much bigger than a sperm cell?
1)It already contains all the chromosomes that will determine the zygote's traits.
2)It must store enough food for the growth of the zygote into an embryo.
3)Its big size allows the sperm to locate it better inside the oviduct.
4)A big ega is easier to implant in the uterus after tertilization.

Explanation:
When a molecule other than substrate binds to the active site of an enzyme and
slows its activity
Definition
Answer:
Competitive inhibition
Explanation:
Competitive inhibition is a type of enzyme inhibition where one molecule inhibits the effect of another molecule (called the substrate) by competing with it for binding at the active site of the target enzyme, thereby preventing the substrate from binding. The active site refers to the specific region of an enzyme that binds with a particular substrate. This mechanism is well-known in pharmaceutics, where specific drugs are designed to show structural resemblance to a particular substrate, preventing its normal function.

Explain the fully developed (Bisporic embryo sac and Tetrasporic embryo sac ) types of embryo sac? in plant
Answer: Embryo sac is the megaspore mother cell.
Explanation:
The bisporic embryo sac can be defined as the comprises of the nuclei that is obtained from two units of the megaspore tetrad on the other hand, the tetrasporic embryo sac comprises of four units of megaspore tetrad. The megaspore mother cell undergoes meiosis to produce megaspore tetrad or four haploid megaspores.

Amylase is an enzyme that digests starch.
A student investigated the effect of pH on the activity of amylase.
This is the method used.
1.
Mix amylase solution and starch suspension in a boiling tube.
2.
Put the boiling tube into a water bath at 25°C.
Remove a drop of the mixture every 30 seconds and test it for the presence of
starch.

Explain the events of the sliding filament theory of skeletal muscle contraction beginning with immediately after the release of Ca++ from the sarcoplasmic reticulum and ending at the end of one cross bridge cycle.
Answer:
According to the sliding filament theory, the myosin (thick) filaments of muscle fibers slide past the actin (thin) filaments during muscle contraction, while the two groups of filaments remain at relatively constant length.
Explanation:
The sarcoplasmic reticulum stimulated to release calcium ions.
Calcium ions bind to troponin. ...
Cross bridges (on myosin) pull on actin (power stroke) ...
Cross bridge detaches from binding sites on actin.
Muscle fiber lengthens & relaxes.
Calcium ions actively pumped back into sarcoplasmic reticul
