How do meiosis I and meiosis II contribute to genetic variation? Because the duplicated chromatids remain joined during meiosis I, each daughter cell receives only one chromosome of each homologous pair. By shuffling the genetic deck in this way, the gametes resulting from meiosis II have new combinations of maternal and paternal chromosomes, increasing genetic […]
How do you tell if a photon is emitted or absorbed?
How do you tell if a photon is emitted or absorbed? The color of the light emitted would result from the amount of energy as it moves through shells. Absorption is shown by the energy levels increasing as the photon gains energy. The wavelengths shown relate to the amount of energy in the photon. Can […]
Can the eye of a hurricane come on land?
Can the eye of a hurricane come on land? Well within this area is the “eye” of the storm. (They can also occur long after the Hurricane is downgraded to a tropical storm and is mostly on land, days after “landfall.”) Hurricane Winds. What happens when cyclone hits land? Hurricane or cyclone can start losing […]
Is walking on toes a sign of autism?
Is walking on toes a sign of autism? Sign up for Toeing the line: Many children with autism cannot easily flex their ankles past 90 degrees, causing them to walk on tiptoes. Children who walk on their toes are more likely to have autism than other forms of developmental delay, according to a study published […]
What are the four types of paralysis?
What are the four types of paralysis? Because paralysis can affect different percentages of the body and different areas, experts classify the condition into four main types: monoplegia, paraplegia, hemiplegia, and quadriplegia. If you’ve been affected, contact a Kansas City spinal cord injury attorney. What are signs of neurological problems? Neurological symptoms that may accompany […]
What is the single most important factor in the development of cancer?
What is the single most important factor in the development of cancer? The use of tobacco products is the single most important factor in increasing cancer risk. The hazards of tobacco are due to a large amount of carcinogenic compounds: those which are already in the tobacco product and those that form during smoking. What […]
What are the 2 types of ossification?
What are the 2 types of ossification? There are two types of bone ossification, intramembranous and endochondral. What are bone cells called? Bone is a mineralized connective tissue that exhibits four types of cells: osteoblasts, bone lining cells, osteocytes, and osteoclasts [1, 2]. Where are osteoblast found? They are found on the surface of the […]
What is the 7 step method?
What is the 7 step method? > The Joiner 7 step method is a technique that can prove very useful in tackling large, complex issues, including in cases where the fundamental problem is not fully understood, and the lack of information can prevent an analytical approach to finding a solution. What are 3 key attributes […]
Why does the solubility of na2so4 decreases with temperature?
Why does the solubility of na2so4 decreases with temperature? In this case, the solubility decreases with increasing temperature because by increasing the temperature you are adding heat to the product side. Inversely, if you pull heat from this system, e.g. cool it, you drive the equilibrium toward the products side and solubility is increased. What […]
Why is convection not possible in solids?
Why is convection not possible in solids? Convection cannot take place in most solids because neither bulk current flows nor significant diffusion of matter can take place. Why is convection not possible in solids for Class 7? In the process of convection, molecules move from a hotter place to a colder region. Therefore, convection is […]
