Hello
I just learned this in health lol
Viral and bacterial infections are both spread in basically the same ways. A person with a cold can spread the infection by coughing and/or sneezing. Bacteria or viruses can be passed on by touching or shaking hands with another person.
Hope this helps
Plz mark me as Brainliest

Answer:</h2>
Option C) All species with similar anatomical structures are related.
<h2>
Explanation:</h2>
- Homologous Structure: A homologous structure is an example of an organ or bone that appears in different animals, which are anatomically similar structure demonstrating descent from a common ancestor.
- All species with similar anatomical structures which means they have homologous structures and are related as they have evolved from a common ancestor.
- Homologous structures shows divergent evolution.
Result: Option C is the correct scientific inference for homologous structures.
Allele for gray fur is A (dominant)
Allele for white fur is a (recessive)
Genotype of heterozygous is Aa (heterozygous is gray, because its allele is dominant)
If we cross two heterozygous
<span>Parents: Aa x Aa
</span> <span>F1: AA Aa Aa aa</span>
The ratio between phenotypes is 3:1 (gray:white)
<span>AA Aa Aa are with gray fur</span>
<span>aa is with white fur </span>
Answer: The progeny of this cross do not conform to a 1:1:1:1 ratio
Explanation: This is because out of the 200 total resulting progeny, we must have 50 in each phenotype class to conform with the 1:1:1:1 which is not so as we have 48 in one of the phenotypic class already. Therefore, it did not conform to the ratio.
I think the answer is c but I looked it up and got this: system or thing used as an example to follow or imitate.
