How do daughter cells compare to parent cells? Daughter cells have roughly the same number of chromosomes as parent cells. They can be produced through either the process of mitosis or meiosis. Cell division is the process that creates daughter cells. It influences how cells replicate and reproduce themselves, along with the manner in which […]
Why is red a danger color?
Why are energy transfers not 100% efficient?
Why are energy transfers not 100% efficient? The second law explains why energy transfers are never 100% efficient. Because ecological efficiency is so low, each trophic level has a successively smaller energy pool from which it can withdraw energy. This is why food webs have no more than four to five trophic levels. How can […]
Which part of plant helps in gas exchange?
Which part of plant helps in gas exchange? stomata How does gas exchange work in plants? Plants obtain the gases they need through their leaves. The gases diffuse into the intercellular spaces of the leaf through pores, which are normally on the underside of the leaf – stomata. From these spaces they will diffuse into […]
Why does light take shortest path?
Why does light take shortest path? Light does travel on the path which would take the shortest time to travel between two points. This nature of light best explains the refraction of light when traveling across two mediums of different refractive index. Light does travel on the path which would take the shortest time to […]
What are the differences between covalent and ionic bonds?
What are the differences between covalent and ionic bonds? The two main types of chemical bonds are ionic and covalent bonds. An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between […]
Why is relative frequency important?
Why is relative frequency important? Relative frequency histograms are important because the heights can be interpreted as probabilities. These probability histograms provide a graphical display of a probability distribution, which can be used to determine the likelihood of certain results to occur within a given population. What is relative class frequency? In a relative frequency […]
How important are energy resources to a human?
How important are energy resources to a human? As the rate of energy consumption continues to grow, competition for dwindling energy resources only makes it more difficult and expensive to keep up the same levels of consumption. One of the reasons that energy resources are so important is that they make it possible for a […]
What disorder means?
What disorder means? Disorder – An illness that disrupts normal physical or mental functions. Oxford English Dictionary. A disorder could be defined as a set of problems, which result in causing significant difficulty, distress, impairment and/or suffering in a person’s daily life. What is an example of disorder? Examples include antisocial personality disorder, obsessive-compulsive personality […]
How do we determine the conditions that existed in the early universe quizlet?
How do we determine the conditions that existed in the early universe quizlet? How do we determine the conditions that existed in the very early universe? We work backward from current conditions to calculate what temperatures and densities must have been when the observable universe was much smaller in size. Why can’t Current theories describe […]
