What statement is true about linked genes? The correct answer is option The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them. What are linked genes? When genes are close together on the same chromosome, they are said to be linked. That means the alleles, or […]

What is the lifespan of a neutron star? 1 million years Can you touch a neutron star? So when anything tries to touch neutron star, it would be suck in by gravity and collapse into lump of neutrons and feed their mass into that neutron star. And if it collects enough mass it would collapse […]

What is crust explain? “Crust” describes the outermost shell of a terrestrial planet. Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. […]

How can I cover the whole syllabus in one day? Divide up the hours in the day and decide what you will focus on when. Make sure you allow yourself time to sleep. Make a list of everything you need to know. Review the syllabus or any handouts given to you by your teacher. How […]

What is the relation between current and intensity? This current is the number of electrons being emitted per second. That is directly proportional to the intensity of the light. So greater intensity means more photons striking the surface and hence an increase in the emitted electrons. The frequency of the light tells is about the […]

Can the scientific method be cyclic? How does it work? The scientific method involves a cyclic process of observation, hypothesis and experimentation. Why is the scientific method not really linear? In contrast to the linear steps of the simplified scientific method, this process is non-linear: The process of science is iterative. Science circles back on […]

When a capacitor is connected to a battery? If an uncharged capacitor C is connected to a battery of potential V, then a transient current flows as the capacitor plates get charged. The flow of current from the battery stops as soon as the charge Q on the positive plate reaches the value Q = […]

How is glucose prevented from leaving the cell? First Half of Glycolysis (Energy-Requiring Steps) This reaction prevents the phosphorylated glucose molecule from continuing to interact with the GLUT proteins, and it can no longer leave the cell because the negatively charged phosphate will not allow it to cross the hydrophobic interior of the plasma membrane. […]

Can there be 2 experimental groups? The experimental group is the set of subjects exposed to a change in the independent variable. It’s possible for an experiment to contain more than one experimental group. However, in the cleanest experiments, only one variable is changed. What do you need to observe to develop a good experimental […]

What happens to the pH of a base when water is added? Adding water to an acid or base will change its pH. The acid is becoming less acidic. Similarly, when an alkali is diluted with water the concentration of OH – ions decreases. This causes the pH of the alkali to fall towards 7, […]
