Explanation:
This discovery demonstrated one of the strengths of Models may be used to expect or provide an explanation for occasions is the statements as it should be describe models in technological know-how.
<h3>What is the importance of models?</h3>
Models have usually been vital in technological know-how and stay used to check hypotheses and expect information. Often they may be now no longer correct due to the fact the scientists of the models.
- Scientific modeling is likewise referred to as a systematic activity. The goal of the modeling can apprehend easier, define, quantify, visualize.
- Normally Science is a topic which can not genuinely provide an explanation for furthermore it's miles to be interpreted.
- There are one-of-a-kind sorts of gift a number of them are mathematical , graphical fashions, operational , etc.
- Scientific are growing withinside the fields of technological know-how schooling and Philosophy of schooling.

Answer: The nucleus.
Explanation: In an atom, there are two main parts, the nucleus and the electron cloud/electron shells. The protons and neutrons are located in the nucleus, and the electrons are located in the electron shells/cloud/whatever.
Answer:
Explanation:
the purple allele (C) is dominant to the pink allele (c).
The frequency of C represents p while that of c represent q. Using the formula p+q= 1
The proportion of pink flower is 153/1000 = 0.153. This is also the frequency of the genotype cc (q^2).
Thud to find q which is the frequency of the c allele,
q = √0.153
q = 0.3912
From the formula p +q = 1 we can find p p = 1 - 0.3912
p which is the frequency of the C allele
p = 0.6088.
B. the proportion of all purple flowering plants that are heterozygotes and homozygotes is 847 / 1000 = 0.847
