What are the three parts of a gene? Genes consist of three types of nucleotide sequence: coding regions, called exons, which specify a sequence of amino acids. non-coding regions, called introns, which do not specify amino acids. regulatory sequences, which play a role in determining when and where the protein is made (and how much […]
What is the difference between a secondary and tertiary consumer?
What is the difference between a secondary and tertiary consumer? The main difference between primary secondary and tertiary consumers is that primary consumers are the herbivores that feed on plants, and secondary consumers can be either carnivores, which prey on other animals, or omnivores, which feed on both animals and plants, whereas tertiary consumers are […]
Is neutron a ray?
Is neutron a ray? Neutron radiation is often called indirectly ionizing radiation. It does not ionize atoms in the same way that charged particles such as protons and electrons do (exciting an electron), because neutrons have no charge. Because neutrons are uncharged, they are more penetrating than alpha radiation or beta radiation. How long does […]
When driving on a wet road you should?
How much fuel does the sun burn in 1 second?
Which of the following is the most common cause of a weight loss plateau?
Which of the following is the most common cause of a weight loss plateau? You may need fewer calories or more physical activity to sustain your lower weight. This is the most likely cause of a weight-loss plateau. How is a drug’s plateau reached? It applies whenever a drug or nutrient is infused or ingested […]
What is the relation between pressure and boiling point?
What is the relation between pressure and boiling point? The pressure of gas above a liquid affects the boiling point. In an open system this is called atmospheric pressure. The greater the pressure, the more energy required for liquids to boil, and the higher the boiling point. Why pressure affects boiling point? Pressure Affects the […]
How many valence electrons does magnesium lose to become stable?
How many valence electrons does magnesium lose to become stable? two electrons Does magnesium have 2 valence electrons? The outer energy level for this atom is n = 3, and it has two electrons in this energy level. Therefore, magnesium has two valence electrons. Does magnesium give or take electrons? In ionic molecules, the metal […]
Why is carbon-13 important?
Why is carbon-13 important? The importance of C13 is all the greater because two of the three radioactive isotopes of carbon decay too rapidly to be suitable tracers, while the remaining one (C14) has so long a life (3,000 years) that its detection by radioactive methods is relatively insensitive. How is carbon-13 used? C-13 is […]
Is circular motion Translatory?
Is circular motion Translatory? 1) Circular motion is the motion when all the particles of a body move along the circumference of a circle. Translatory motion is a motion when all the particles of a body either move in a straight line or a curved fixed path. What are the three types of translatory motion? […]
