What do viruses inject into cells? During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it. During uncoating, replication, and assembly, the viral DNA or RNA incorporates itself into the host cell’s genetic material and induces it to replicate the viral genome. How do viruses attach […]
Which metal is used in wires?
Which metal is used in wires? Copper Which wire can carry a higher current? Answer. “In solid wire of same length resistance of that wire is higher than stranded wire”. Hence stranded wire carries more current than solid wire due to lower resistance. Thus due to extra surface area more surface current flows Therefore in […]
What is alpha decay paradox?
What is alpha decay paradox? Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or ‘decays’ into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two. It […]
Where do most plants get light from?
Where do most plants get light from? the Sun What do plants take up through their roots? Plants absorb nutrients and water through their roots, but photosynthesis — the process by which plants create their fuel — occurs in the leaves. Sap is the mix of water and minerals that move through the xylem. Do […]
What is an independent contractor costs?
What is an independent contractor costs? Independent contractors are paid gross pay with no tax withholding. That means they handle their own taxes and provide their own benefits. The total paid to the employee really should include the cost of benefits. Suppose that a company pays $50 in direct pay to an employee or $50 […]
What mineral has the highest specific gravity?
What mineral has the highest specific gravity? Osmium Which is the most reliable clue to a mineral’s identity? streak plate Why is color not reliable for identification? Many minerals are colored by chemical impurities. Other factors can also affect a mineral’s color. Because color alone is unreliable, geologists rarely identify a mineral just on its […]
How much heat is needed to melt 23.50 kg of silver that is initially at 25 C?
How fast does a speaker vibrate?
Can you have a negative enthalpy?
Can you have a negative enthalpy? A negative enthalpy represents an exothermic reaction, releasing heat. A reaction that absorbs heat is endothermic. Its enthalpy will be positive, and it will cool down its surroundings. This reaction is exothermic (negative enthalpy, release of heat). What is the enthalpy of an exothermic reaction? Exothermic reaction: In an […]
What are the characteristics of groups?
What are the characteristics of groups? Instead, a primary characteristic of groups is that members of a group are dependent on one another for the group to maintain its existence and achieve its goals….Group Communication Then Synergy. Common Goals. Shared Norms. Cohesiveness. What are five characteristics of a group on the periodic table? Group= Total […]
