Absolute dating methods determine how much time has passed since rocks formed by measuring the radioactive decay of isotopes or the effects of radiation on the crystal structure of minerals. Paleomagnetism measures the ancient orientation of the Earth's magnetic field to help determine the age of rocks.
Smooth, rounded characteristics such as large eyes, fat cheeks, and a large head (i.e. babies) is very appealing to humans and other species (the way we call it "cuteness") which is a stimuli that promotes caring of babies and young children. This is also the same principle why humans find puppies, kittens, and other baby animals cute and want to care for them.

Answer:
The correct option is b. LTM (long term memory) is not disrupted.
Explanation:
Amnesia is a type of disorder that affects our memory, we talk about anterograde amnesia when it involves a serious damage/lost in our short-term memory (the long term memory is not disrupted), that is, it is the inability to create new memories. This selective memory deficit is caused by a brain lesion located in the hippocampus and in the areas of the medial temporal lobe. The hippocampus has the function of generating new memories, if it is affected, then it will be impossible to establish the memories.
Answer:
At least 17 PCR cycles or 16 PCR cycles
Explanation:
As we know -
In one chain of heating and cooling of polymerase chain reaction (PCR), the strands of DNA gets doubled.
The general mathematical representation of this is
where "n" is the number of PCR cycles.
It is given that DNA strands to be produced is 16 times the original quantity of DNA.
So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less than 16 times the original quantity of DNA
