Explanation: d).
Sometimes it is possible to neglect an external impulse if it is not in the direction of interest.
Also, a small force acting over a long time can easily provide more impulse

Answer:
A substitution mutation changes the codon CCC to the codon CCA, both code for proline, the type of mutation happens in this case is called as "Silent mutation"
Explanation:
It is a base substitution method without a change in the amino acid. In some cases.In this method of mutation ,the amino acid is changed while the translation of mRNA. Example, when CCC is altered to form CCA, the amino acid remains same, as well as both the code for the proline. Silent mutation happens due to the result of change in the single DNA nucleotide, inside the protein coding. This alteration or change will not affect the sequence of amino acid rather build up the gene's protein. They never show any effect on the growth and survival of the living being.
Answer:
Presence of inorganic molecules
Explanation:
This prediction is often debated as a part of origins of life.
Inorganic molecules do not contain carbon and cannot be considered as biological organism. One theory predicted that before the first life form exist, early atmosphere is covered in inorganic molecules. Over time, the interaction with inorganic molecules and lightning might cause a reaction that resulted in the formation of building blocks amino acids and nucleotide, which eventually evolved into living organism.
Answer:
distrustful of the British
used enslaved Africans
allowed to keep their country
Explanation:
Strong initiative, independence and decisiveness are characteristics of the boer, developing out of their pioneering spirit and the difficult circumstances of their early history and the political dominance of the British.
The Afrikaans are also known as the “Boers,” the Dutch word for “farmers.” To aid them in agriculture, the Europeans imported slaves from places such as Malaysia and Madagascar while enslaving some local tribes, such as the Khoikhoi and San.
The South African Boer War begins between the British Empire and the Boers of the Transvaal and Orange Free State. The Boers, also known as Afrikaners, were the descendants of the original Dutch settlers of southern Africa.
By 1902, the British had crushed the Boer resistance, and on May 31 of that year, the Peace of Vereeniging was signed, ending hostilities. The treaty recognized the British military administration over Transvaal and the Orange Free State, and authorized a general amnesty for Boer forces.
Many of these farmers settled in the fertile lands around Cape Town and used slaves, some of whom were brought in from other Dutch territories, to work their farms. The colony was administered by the Dutch East India Company for nearly 150 years
