Answer:
different species
Explanation:
weeds and vegetables are both plants, but they are completely different types of plants.
The correct answer is Carbon Dioxide.
<h3>
What are carbon bonds?</h3>
- Because each carbon is identical, they all contain four valence electrons, so they can easily bond with different carbon atoms to form extended chains or rings. A carbon atom can bond with another carbon atom two or three times to create double and triple covalent adhesives between two carbon atoms.
- The partial payments on the fluorine and carbon are beautiful, contributing to the unusual bond power of the carbon-fluorine bond. The bond is marked as "the strongest in organic chemistry," because fluorine forms the strongest single bond to carbon.
- In chemistry, a covalent bond is the strongest bond. In such bonding, every two atoms transfer electrons that bind them concurrently. For example, water molecules are bonded jointly where both hydrogen atoms and oxygen atoms transfer electrons to form a covalent bond.

Answer:
None of these
Explanation:
Friedel–Craft reaction is a reaction involves the attachment of substituents to the benzene ring.
Mechanism of the reaction of methylbenzene with 1-chlorodecane in the presence of ether and aluminum chloride :
Step -1 : Generation of stable carbocation.
Aluminium chloride acts as Lewis acid which removes the chloride ion from the alkyl halide forming carbocation. The primary carbocation thus formed gets rearranged to secondary primary carbocation which is more stable due to hyperconjugation.
Step-2: Attack of the ring to the carbocation
The pi electrons of the ring behave as a nucleophile and attacks the carbocation. Since, the group attached on the benzene is methyl (+R effect) , the attack is from the ortho and the para positions. Para product is more stable due to less steric hinderance.
The product formed is shown in mechanism does not mention in any of the options.
So, None of these is the answer
Since Seismic waves travel at different speeds according to type, the speed of seismic waves from fastest to slowest is option C: P waves, S waves, L waves.
<h3>Which seismic waves are moving more quickly?</h3>
P waves leave the earthquake first and go the furthest. Rock oscillates perpendicular to the direction of wave propagation in S or shear waves. In rock, S waves typically move at a pace of roughly 60% that of P waves, and they always come after the latter.
Therefore, if we examine a seismogram, we anticipate that the P-wave, which is the quickest wave, will arrive first, followed by the S-wave and then the Love and Rayleigh waves, which are the slowest waves.

Answer:
Rift valleys
Explanation:
An example is the Great Rift Valley in Africa. As plates move apart, they leaves a gap in the crust.
