Answer:
B. It's much harder to provide the right atmospheric environment to cultivate obligate anaerobes, so it's been harder to study them.
Explanation:
Obligate anaerobic bacteria are the ones that can grow only in the absence of oxygen. These bacteria do not derive the energy from aerobic cellular respiration and die when exposed to the presence of oxygen.
Owing to their oxygen sensitivity, the culturing of obligate anaerobic bacteria requires special equipment to ensure the absence of oxygen.
The presence of aerobic conditions in laboratories makes their culture and study harder than that of the aerobic or facultative anaerobic bacteria.
As a matter of terminology, albino guinea pig actually refers to a white fur guinea pig, whose genotype is homozygous recessive (bb).
If it crossed with a black fur guinea pig and gave 5 black fur offsprings, there is a good chance that the black fur parent is homozygous dominant (BB).
The Punnett square would be as follows:
B B
b Bb Bb
b Bb Bb
So they are all heterozygous black fur offsprings.
However, it is not impossible that the black fur parent be heterozygous, namely
B b
b Bb bb
b Bb bb
Giving a 50% chance on each colour. Thus it is possible (with probability 1/32) that all five offsprings are heterozygous black fur if one of the parents was heterozygous.
In the second case, a homozygous recessive and a homozygous dominant parent will never give a white offspring. So it is sure that the black fur parent is heterozygous, with the following Punnett square:
B b
b Bb bb
b Bb bb
With a 50% probability for each of Bb (black fur) and bb (white fur).
the distribution 4,3 demonstrates this perfectly.
Answer:
I had a long answer that I would have loved to share but I can't because brainly does not like the words using and there is no way around it, tried using every synonym on the internet... LOL sorry
1) 35mL to L 1 L = 1000ml so, 35mL = 35÷1000=0.035L
2) 950gm = 1Kg =1000g SO, 950÷1000= 0.950 Kg
3) 275mm to cm= 1mm= 1÷10 cm so, 275÷10= 27.5cm
4)1000mL to L = 1L=1000ml so, it will equal to 1L
5)4500mg to g = 1mg= 1÷1000g so, it will equal to 4.5g
6)25cm to mm = 1cm= 10mm so, 25X 10= 250mm
7)0.005Kg to mg, so 1Kg= 10∧6 mg so, 0.005X10∧6= 5000mg
8)0.075m to cm, so 1m =100cm so, 0.075X100= 0.75cm
9)15 g to mg , so 1g = 1000mg so, 15X1000= 15000mg
