What are expected from a mating a roan bull and a roan cow

Answers

Answer 1

Answer: The allele for black is B and the allele for white is B1. The heterozygous phenotype is known as erminette (black and white spotted). In shorthorncattle, when a red bull (R R) is crossed with a white cow (R1 R1), all the offspring are roan—a spotted, red and white or milky red color.

A scientific argument will be considered invalid if the evidence supporting that argument is based ona. inconsistent data.
b. independent data.
c. unlimited results.
d. controlled results.

Answers

I believe the answer to this is (B) independent data. Independent data can be obtained in an uncontrolled environment and can also be biased. Scientists depend upon each other to test each others data and results, but this isn't always the case with independent data and therefor the credibility is reduced.

The reason the other answers are incorrect is that unlimited and controlled results do not affect the validity of research, and inconsistent data means just that....that it is inconsistent and most likely requires more research or testing, but isn't necessarily wrong or invalid.

Explanation:

Which type of reaction separates atoms or molecules into its individual components?

Answers

Chemical reactions that occur when one or more substances are charged into other substances. Thus can happen when two or more elements or compounds combine with each other. When one compound breaks down into two or more molecules or when electrons are added to or taken away fro an atom.

Scientists today can use many experimental methods to study evolution. Which method was developed after Darwin’s time?DNA comparisonsobservationsfossilsexperimentation

Answers

DNA comparisons was developed after Darwin's time and have become an important method for studying evolution.

While Darwin was able to make observations of variation and adaptation in different species, he did not have access to the genetic information that DNA provides. It wasn't until the discovery of the structure of DNA in 1953 that scientists began to explore the use of DNA in studying evolution.

Since then, DNA sequencing and comparisons have become increasingly important tools in the study of evolutionary relationships and processes.

In science, DNA comparison is a ground-breaking technology. It has given researchers the ability to compare and contrast DNA samples with previously unheard-of accuracy.

Researchers can learn a great deal about genetic links and diseases as well as create brand-new remedies for illnesses by examining these traits.
