Answer:
78 chromosomes
Explanation:
Since the number of chromosomes in a dog are diploid, we have 2n chromosomes where n = number of chromosome pairs.
Since n = 39.
The number of chromosomes is 2n = 2 × 39 = 78 chromosomes
So, a dog has 78 chromosomes.
Answer:
Explanation:
If the DNA codons are altered in an organism, the genetic code will be inaccurate. This will result in genetic mutations and disorders, depending on how drastic the change was. The two types of mutations are point mutations, that just replace one nucleotide. There's also frame shift mutations, where the amount of codons are incorrect.
D. seems the most probable since plastic is barely biodegradable.
I want to Say A - I searched google and it said that Archaea has something called membrane lipid bonding, ( which is oils and fat ) I didn't see anything about nucleus, size, or cell wall.
Hope this helped!
Considering the answers;
A. are still sibling species
B. shared a common ancestor more recently with each other than either did with the other two species
C.May merge into a single species if their hybrids remain fertile over the course of many generations.
D. A and B only
E. A, B, and C
The answer will be E.
If no other species can hybridize, then species W and Y are still sibling species, shared a common ancestor more recently with each other than either did with the other two species and also may merge into a single species if their hybrids remain fertile over the course of many generations.
