Answer:

The bowling ball would hit the ground faster.

Explanation:

I know this because the bowling ball has a greater mass than the tennis ball causing the gravity to pull it faster.

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

While le examining a rock surface, you have discovered an interesting new organism. Which of the criteria will allow you to clas

jasenka [17]

Answer:

The correct answer is- B) Cell walls are made primarily of peptidoglycan

Explanation:

There is a difference between the cell wall of bacteria, archaea, and eukarya. The cell wall of bacteria is primarily made up of peptidoglycan which contains two sugar N-acetylglucosamine and N-acetylmuramic acid while archaea contain two N-acetyltalosaminuronic acid (NAT) in place of N-acetylmuramic acid which is called pseudo-peptidoglycan.

Eukaryotic cell wall is also different from archaeal and bacterial cell wall and animals in eukaryotes do not have a cell wall. Therefore cell wall made up primarily of peptidoglycan will allow you to classify the organism as belonging to Bacteria but not Archaea or Eukarya.

Did alleles for drug resistance occur in bacterial populations that afflict humans

Cerrena [4.2K]

Answer:

Did alleles for drug resistance occur in bacterial populations that afflict humans, prior to the widespread use of antibiotics in medicine and agriculture? a. No—mutations for drug resistance occur in response to antibiotic use. ... Yes—alleles for resistance arise due to random mutation, so are always present.
