Which of the following explains the conservation of mass during cellular respiration? (4 points) a The total number of atoms when carbon dioxide and oxygen react stays the same when glucose and water are produced. b The total number of atoms when water and oxygen react stays the same when glucose and water are produced. c The total number of atoms when carbon dioxide and water react stays the same when glucose and oxygen are produced. d The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced.
Answers
Answer:
D- The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced.
Explanation:
The conservation of mass during cellular respiration can be explained by the fact that after cellular respiration which occurs due to the oxidation of glucose to produce carbon dioxide and water, the number of atoms on the right hand side (RHS) of the reaction remain same as of left hand side (LHS) of the reaction.
The balanced chemical equation is mentioned as under:
C₆H₁₂O₆ + 6 O₂ -> 6 CO₂ + 6H₂O + Energy.
(Glucose) (Oxygen) (Carbon (Water)
dioxide)
If we will see carefully, the number of atoms of each element on RHS & LHS of the equation are same i.e. there are 6 atoms of C, 18 atoms of O and 12 atoms of H on both the sides.
1. This question may be completed independently or as a group exercise. Biological anthropologists disagree about the best way to classify the robust australopithecines. Describe the two approaches to classifying these species. Which classification do you support
Answers
Answer:
Some researchers classify Australopithecines into gracile australopithecines and robust australopithecines, while others argue that differences are enough strong to classify robust australopithecines in their own genus called 'Paranthropus'. In my opinion, it seems reasonable to obtain more fossil data in order to support this division
Explanation:
The term Australopithecines comes from the genus Australopithecus, which are the closest known relatives of our genus Homo, and arose around three (3) million years ago. Australopithecines can be classified into two major groups called gracile australopithecines and robust australopithecines. However, robust australopithecines have also been classified in their own genus, Paranthropus, in order to distinguish them from the gracile australopithecines. The major differences between gracile and robust species are associated with facial and cranial features. Paranthropus species had a large sagittal crest, enormous cheek teeth, robust jaws, and strong jaw muscles (suggesting they were herbivores that ate tough food). However, these main features may not be conclusive evidence that supports the separation of Paranthropus in its own clade, thereby in my opinion it should be reasonable to wait until more fossils are found in order to correctly classify Paranthropus species as a different group.

In mouse, genes X, Y and Z are on chromosome 2. The map of genes X, Y and Z is:
X--------20mu--------Y---------------30mu---------Z.
You cross an individual with genotype XXYYZZ to an individual with genotype xxyyzz, and F1 progeny are collected. Assume interference between regions (X-Y and Y-Z) is 40%. You then perform a cross between an F1 individual and an individual with genotype xYz/xyz. Among 1000 progeny, how many of them will be of the genotype xxyyzz?
Answers
Answer:
36 individuals xxyyzz
Explanation:
Available data:
X-Y = 20MUY-Z = 30MUCross: XXYYZZ x xyyzzF1= XxYyZzI = 40%2nd Cross: XxYyZz x xxYyzzF2 = 1000 individualsWe need to know how many individuals from the F2 are going to be xxyyzz
xxyyzz genotype is the result of a double recombinant event.
First, we need to analyze the given information:
→ Distances between genes
The genetic distance result from multiplying the recombination frequency of each region by 100 and expressing it in map units (MU). So, if we have the genetic distance we can divide it by 100 and get the recombination frequency:
Let us say that region I is the distance between X and Y. And region II is the distance between Y and Z.
GD = genetic distance
RF = Recombination frequency
GD (X-Y) = RF x 10020MU = RF x 100
20MU/100 = RF
0.2 = RF (Region I)
GD (Y-Z) = RF x 10030MU = RF x 100
30MU/100 = RF
0.3 = RF (Region II)
Now we have the recombination frequency of Region I and Region II.
→ Interference
Knowing the interference value will let us know the value of the coefficient of coincidence, which will also lead us to the number of individuals xxyyzz.
I = 40%
I = 1 - CC ⇒ CC = coefficient of coincidence
Clearing this equation gives us the value of CC
CC = 1 - I
CC = 1 - 40% = 1 - 0.4
CC = 0.6
To calculate the coefficient of coincidence, CC, we can also use the next formula:
CC = observed double recombinant frequency/expected double recombinant frequency
Now, we are interested in knowing the value of the observed double recombinant frequency.
Note:
observed double recombinant frequency = total number of observed double recombinant individuals/total number of individuals expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II.So, to get the value of the observed double recombinant frequency, first, we need to get the value of the expected double recombinant frequency. And we can do it because we already have the recombination frequencies in both regions.
expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II
- Recombination Frequency - RI = 0.2
- Recombination Frequency - RII = 0.3
expected double recombinant frequency = 0.2 x 0.3
expected double recombinant frequency = 0.06 = EDRF
Now that we know the value of the CC and the expected DRF, we can get the observed double recombinant frequency.
CC = observed double recombinant frequency/expected double recombinant frequency
- CC = 0.6
- EDRF = 0.06
CC x expected double recombinant frequency = observed double recombinant frequency
0.6 x 0.06 = observed double recombinant frequency
0.036 = observed double recombinant frequency = ODRF
Finally, as this is a frequency, we need to multiply it by the total number of individuals in the F2 to get the number of observed double recombinant individuals.
- ODRF = 0.036
- N = 1000
Double recombinant individuals = 0.036 x 1000 = 36 individuals xxyyzz.
