Answer: Mendel would have concluded that one pair of factors (genes) is responsible for two different characters in plants.
Explanation:
The 9:3:3:1 ratio observed by Mendel helped him to form his <em>Law of Independent Assortment </em>which states that the inheritance of one pair of factors (genes) is independent of the inheritance of the other pair.
Also from his previous studies, he obtained a 3:1 ratio for a single gene expression, flower color, which enabled to form <em> the Law of Segregation</em>, which states individuals possess two alleles and a parent passes only one allele to his/her offspring.
However, if he had observed a 3:1 ratio for two traits, he would have concluded that inheritance of characters occurs in pairs i.e., that a pair of alleles is responsible for two different characters in plants.

Answer:
if sex cells were identical, there won't be genetics variations and we will just all be identical to our parents. genetic variation allows us to better adapt and survive
The correct answer is two hydrogen bonds between adenine and thymine (the bond is thus weaker and longer) and three between cytosine and guanine.
A hydrogen bond is a bond formed between a hydrogen (H) atom and electronegative atom or group, such as nitrogen (N), oxygen (O), or fluorine (F).
Hydrogen bond is found in the double helical structure of DNA between its base pairs. Guanine is complementary linked with cytosine and adenine with thymine. Thanks to hydrogen bonds one complementary strand is connected to the other and replication is enabled.
Answer:
c) Ras Binds steroid hormones
Explanation:
Ras which belongs to a protein family, which are used in the transmission of the signal within the animal cell. It should be noted that The protein in Ras is associated to Gpase.
The characteristics of Ras are:
✓ Ras is activated by Sos, a guanine nucleotide exchange factor
✓Ras activates a cascade of phosphorylation events within the cell
✓ Ras is monomeric
✓ Ras activity is inhibited by GTPase activating proteins.
Therefore, all the options are true about Ras except C.
