Answer:

Sodium will let that electron go as soon as it can, which is why it generally forms ionic compounds such as NaCl. When sodium atom loses an electron from its outer energy shell, it becomes Na+ ion. D is the answer

NEED HELP ASAP! WILL GIVE BRAINLIEST

Hey there! :D

When we are talking about gametes, we can use a punnet square, or in this case, common knowledge. If two of the alleles for one phenotype are the same, we can infer there will only be two variations of the genotype. (because there are two dominant SS genes) We already know that "D" must be the answer. Firstly, there will be one allele for each gene, so there will always be an "S" and a "T" no "SS" or "tt" (when talking about gametes). That leaves us with B and D but there is no recessive "s" in the original genotype, so the answer must be "D".

I hope this helps!

Answer all parts of the question:

tamaranim1 [39]

Answer:

a. 0.03054 b. 0.000032 c. sorry I am not perfect

Explanation:

a. In the number 0.03054 , you need to move the decimal point two places to the right to get to 3.054 (which is between 1 and 10). Since you moved the decimal point two places to the right, you must indicate it by saying that you multiplied 3.054 by 10−2 . Think about it: 3.054×10−2=0.03054 .
b. Answer: 0.0000302 Step-by-step explanation: When 10 is to the power of a negative number, "move" the decimal dot left. 10⁻⁵ means to "move" the decimal 5 times to the left. 1. Write a bunch of extra 0's for the coefficient. (The coefficient is 3.02). 0000003 . 02 2. Count 5 place values over. 00←0←0←0←0←3 . 02 3. Put the decimal behind the digit. 00 . 0000302 4. Get rid of the 0s that you don't need. You only need one 0 left of the decimal. 0.0000302 <= Final answer
c. sorry but I am not perfect at this

In hamsters, we can examine the genes for coat color and eye color which are linked:B = brown coat, b = white coat, G = green ey

Inessa [10]

Answer:

10.2 cM

Explanation:

Given,

pure breeding parent 1 : BBgg = brown coat and pink eyes

pure breeding parent 2 : bbGG = white coat and green eyes

BBGG X bbgg = F1 = BbGg ( All are brown with green eyes )

When F1 progeny is test crossed with white coat and pink eyes hamster:

BbGg X BbGg = F2 =

brown, pink eyes = 99 = parental

white, green eyes = 103 = parental

brown, green eyes = 12 = recombinant

white, pink eyes = 11 = recombinant

Recombination frequency =

(total number of recombinants / total progeny ) * 100

= [( 11 + 12 ) / ( 99 + 103 + 12 + 11 )] * 100 = (23/225)*100 = 0.102 * 100 = 10.2 %

1 % recombination frequency = 1 cM distance between genes

Hence, the distance between B and G gene is 10.2 cM
