Answer:
There was no sulfur compound added to the medium, that could be used as an electron donor.
Explanation:
Bacteria that use light for energy requirements mean that they get their energy from photosynthesis and transferring energy through the molecules.
Bacteria play a major part in the reductive and oxidative cycle of the sulfur which is mediated by the help of photosynthetic bacteria, so the sulfur or sulfur compounds are major requirements for their growth in the habitat or the medium.
Thus, the correct answer would be- There was no sulfur compound added to the medium, that could be used as an electron donor.
Explanation:
Cut off the tail at the base. Using an EXTREMELY sharp skinny knife, start separating the hide from the meat, staring at the cuts that you made on the rear legs. You'll notice that the skin starts to kind of peel off - use the space to continue skinning.
Corrected Question:
The picture shows the dihybrid cross of 2 guinea pigs.
1. What is the genotype of the parents?
2. What is the phenotype of the parents?
3. What is the genotype of their baby guinea pig (in the empty box)?
a. BbRr - black rough fur
b. Bbrr - black smooth fur
c. bbRr- white rough fur
d. bbrr - white smooth fur
Answer:
Genotype of parents is BbRr as seen in the cross.
Phenotype of the parents is black rough furred.
The genotype of the baby in the empty box is bbRR.
Option D
<h3><u>
Explanation:</u></h3>
This representation of the genetic crossing is called as Punnet square, after the name of the scientist who discovered this process to denote the probability of finding the required genotype in a statistical way.
Here both the parents are heterozygous black and rough furred, with the genotype of BbRr.
So the gametes from the parents are = BR, Br, bR, and br from both the parents which are represented in the Punnet square.
Thus we can get 16 types of genetic combinations among the offsprings.
D. scientists can easily tell which variable caused the results.
Good luck!
