Answer:

The correct answer is A (XRXr, XRXr, XRY, XRY) becouse

R- is about red color

r- is about white color 

if we have Rr ( XRXr)- that will be red color 

white color is only when is only "r" (XrY) or only "rr"  ( XrXr)

Proteins that speed up the rate of chemical reactions in the cell without requiring high temperatures are antibodies.
Ymorist [56]

The fruit fly Drosophila melanogaster is an important model system for studying inheritance in animals and genetic control of an
Snezhnost [94]

Answer:

The correct answer is "strengths: inexpensive, easy to culture, short life cycle, large number of offspring; weaknesses: invertebrate model, some diseases such as immunological cannot be modelled, anatomical features are very different from humans"

Explanation:

The fruit fly <em>Drosophila melanogaster</em> is one of the most used animal model for genetic and biomedical studies. There are many advantages of using Drosophila as model, including that it is very inexpensive to handle, it is easy to culture, it has a short life cycle allowing to observe the changes in phenotype very quickly and its large number of offspring allows to include several repetitions per trait in a study. However, there are some weaknesses of using Drosophila to study human biology. First, obviously the fruit fly is very different from humans, it is an invertebrate and its anatomical features are very different, which makes impossible to model some disorders such as immunological diseases.

Oksi-84 [34.3K]
<span>Meiosis reduces chromosome number so that sex cells (eggs and sperm) have a half set of chromosomes–one homolog of each pair. This is the haploid number. CONGRATULATIONS! YOU'RE SO SMART!</span>

Which of the following is not a reason for the wide use of CFC's during the 1920's - 1990's?
Mila [183]
CFCs are Chlorofluorocarbon substances used in refrigerants (subtances used to keep other things cold) and in aerosol products.

they are both relatively nontoxic(nonpoisonous) and nonflammabale - at least as compared to alternatives.

They are rather volatile - they are not very stable. Therefore it does not make sense to say that they are strong - the correct answer is then strength.
