Answer:

Genetics

Explanation:

Genes are the stretch of DNA that code for a specific protein product. Genes are present in linear order on chromosomes and are carried from one generation to next via chromosomes.

Genes regulate the genetic traits and make the progeny and siblings have shared genetic traits. Shuffling of genes during sexual reproduction imparts certain new genetic traits to the progeny. This is the reason that the progeny of sexual reproduction is not genetically 100% identical to the parents.

The transmission of genes from parent to progeny, regulation of genetic traits by genes, heredity, and variations caused by genes are some of the aspects that are studied in genetics. Therefore, the study of structure, functions of genes and associated heredity and variations is called genetics.

How do geologists determine the age of a fault line??
V125BC [204]
Geologists rely on the Rule of Superposition to determine the age of geological structures. This rule assumes that no significant event took place and so older rock layers are positioned below the newer ones, similar to a stack of dirty dishes, where the newer ones are added on top and the older ones are further below.

A sample of rock is found to contain 200 grams of a parent isotope.how many grams of the parent isotope will remain after one ha
emmasim [6.3K]

Answer: 100 grams of the parent isotope will remain after one half life.

Explanation:

Mass of the isotope present at initial stage = N_o=200 g

The mass of the parent isotope left after the time ,t=N

Time taken by the samle ,t = t_{\frac{1}{2}}

The half life of the sample :t_{\frac{1}{2}}

N=N_o\times e^{-\lambda t}

\lambda =\frac{0.693}{t_{\frac{1}{2}}}

\ln[N]=ln[N^o]-\frac{0.693}{t_{\frac{1}{2}}}\times t_{\frac{1}{2}}

2=\frac{[N_o]}{[N]}

[N]=\frac{N_o}{2}=\frac{200 g}{2}=100 g

100 grams of the parent isotope will remain after one half life.
