Can someone please help me with the answers to i and ii f.
The birth rate in the lynx population can be estimated by determining
litter sizes. Litter size can be determined by two methods. The first
method involves counting the number of placental scars on the uterus of
a lynx carcass. A scar is left at each implantation site of a fetus. The
second method involves counting the number of degenerated corpora
lutea (plural of corpus luteum) in the ovaries of the lynx carcass. Neither
of these methods provides a completely accurate value for litter size.
Explain why each method produces an overestimation of actual litter size.
i. counting placental scars
ii. counting degenerated corpora lutea

the animal that would be cutest if scaled down to the size of a cat? elephant

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
