According to the question, behavior of children is based upon evolutionary forces that is acting as foundation to the quarreling behavior pattern of them.Thus, children can argue over any small topic of unfair behavior towards them.
Answer:
The rock is 3.75 billion years ago.
Explanation:
Given that:
Half life = 1.25 billion years
1 billion years = 10⁹ years
So,
Half life = 1.25 × 10⁹ years

Where, k is rate constant
So,


The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹
Initial amount [A₀] = 80 micrograms
Final amount
= 10 micrograms
Using integrated rate law for first order kinetics as:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D)
So,





So,
<u>The rock is 3.75 billion years ago.</u>
Answer: Option (D) is correct
Explanation:
Economic efficiency is referred to as the situation where all commodities and factors of production residing within an economy are allocated or distributed in most efficient way in order to eliminate or minimize waste. It also implies to an state(economical) where resources are being optimally allocated in order to serve individuals or other entity in best way possible while trying to minimize inefficiency and waste.
An undeveloped prefrontal cortex is partially responsible for impulsiveness in young children. The prefrontal cortex, which is a part of the brain located at the front of the frontal lobe, is the "executive" of the brain, because it is a crucial part of the brain, involved in planning, prioritizing, and reflection. If not fully developed these functions are not working properly.
