Answer:
The help determine age, gender, race, and height
Answer:
The correct answer would be - 1. group 2.period 3. less 4. more
Explanation:
elements that have a place with same group contains same number of valence electrons. Thus, they will in general show comparable chemiccal properties.
At the point when we move over a period at that point number of electrons get added to a similar shell. Therefore, there will be no expansion in size of elements.
Additionally, metals are the elements that have a place with group 1, 2 and d-block group are otherwise called metals. Metallic character of elements diminishes when we move left to directly in a periodic table.
As most responsive metals are put on the left half of occasional table.
Since, size of elements increases on descending the groups. Along these lines, a elements can lose its valence electrons due to the less forrce of ttaraction between valence electrons and its neucleus.
Option A. received less money for their crops is the correct answer.
The Green revolution's large crops made poor farmers to receive less money for their crops. As the production increased to a large extent due to the Green Revolution, it lead to the fall of prices of crops and thus the poor farmers had to sell their crops at cheap rates.
Respiratory system and Circulatory system :P
Correct answer: Genetic Drift
Genetic drift is defined as the random change in the allele frequency of a population is changed by chance or due to random changes in the environment. It is a random process that can lead to large changes in the overall population in a short period of time. It is a mechanism of evolution and it does produce the adaptation.
Hence, the correct answer would be genetic drift.
