What is difference between invertebrates and vertebrates? Vertebrates are more complex organisms when compared to invertebrates. The primary difference between the two is that vertebrates possess a backbone and an internal skeleton. What are the five fish vertebrate classes? Vertebrate Classification. Vertebrates can be subdivided into five major groups: fishes, amphibians, reptiles, birds, and mammals. […]

What is the net force of a rock falling at constant terminal velocity? Objects falling through a fluid eventually reach terminal velocity . At terminal velocity, the object moves at a steady speed in a constant direction because the resultant force acting on it is zero. Why does a parachutist does not fall with constant […]

Why is cohesion in water important? The cohesion of water molecules helps plants take up water at their roots. Cohesion also contributes to water’s high boiling point, which helps animals regulate body temperature. How do you use the word cohesive? Cohesive in a Sentence ? To make perfect pie dough, you must mix the ingredients […]

What sport has the worst injuries? Believe it or not, basketball actually has more injuries than any other sport, followed by football, soccer and baseball. Common sports injuries include hamstring strains, groin pulls, shin splints, ACL tears and concussions. What care should be taken when using sports equipment? Contents 1 Introduction. 2 Protective Materials. 3 […]

What is the difference between speed and power in PE? Power is the ability to exert as much force as possible in the shortest amount of time. To put it simply, speed + strength = power. When it comes to power, you won’t be able to lift as much weight as you would if you […]

What is the importance of formulating a hypothesis? A hypothesis enables researchers not only to discover a relationship between variables, but also to predict a relationship based on theoretical guidelines and/or empirical evidence. Developing a hypothesis requires a comprehensive understanding of the research topic and an exhaustive review of previous literature. What is a broader […]

Is N bigger than 2 N? n! eventually grows faster than an exponential with a constant base (2^n and e^n), but n^n grows faster than n! since the base grows as n increases. Every term after the first one in n^n is larger, so n^n will grow faster. Does N 2 grow faster than 2 […]

What has an atomic number of 36? The Elements, sorted by Atomic Number Atomic Number Symbol Name 35 Br Bromine 36 Kr Krypton 37 Rb Rubidium 38 Sr Strontium Is krypton a real element? Krypton (Kr), chemical element, a rare gas of Group 18 (noble gases) of the periodic table, which forms relatively few chemical […]

What do u mean by uniform circular motion? Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. Nonetheless, it is accelerating […]

Why do we see sun before sunrise? The rising sun is visible to us before actual sun rise and after actual sunset because of the atmospheric refraction of light. The rays from the sun coming through space enter from rarer to the denser medium and hence bend slightly towards normal at each refraction and become […]
