Answer:
The option<u><em> D) increases reproduction of native species</em></u> is NOT an impact that an invasive non-native species has on an ecosystem.
Explanation:
Introduction of a non-native species into a stable ecosystem can be very threatful to the ecosystem. The non-native species will compete for resources with the native species of the area. As a result, there will be severe competition. The competition might lead to migration of the native species or them being endangered on the whole. Also, the introduction of a non-native species will result in the extinction of a particular prey as it will have an increase in the number of predators.
Answer:
Non polar covalent bond.
Explanation:
The covalent bond is polar when the electronegativity difference of bonded atom is greater than 0.4. If the electronegativity difference is 0.4 or less than this the bond will be non polar.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive and the bond is polar.
In case of F₂ the electronegativity difference is zero that's why the bond is non polar covalent bond.
sorry what us this i don't get it
The answer is 4 hope it helped
Answer:
15 grams of water will absorb 2,500 Joules in going from 20.0 to 60.0 C.
Explanation:
The heat involved in raising a mass (m) of a substance with a specific heat (c) from one temperature to another (Delta T) is given by:
Heat = mc(Delta T)
2,500 Joules = m*(4.186J/gC)*(60C-20C)
2,500 Joules = m*(4.186J/gC)*(40C)
2,500 Joules = m*(4.186J/gC)*(40C)
m = (2,500J)/(4.186*40J/g)
m = 14.93 grams
