Answer:
Option C, 32 million
Explanation:
As per standard rule -
Number of base pair per nucleosome is equal to 
Now, the total number of base pair in human genome is 
billion.
Number of nucleosome in billion base pairs is equal to
These are diploid cells and hence the number of nucleosomes will be 2n
Hence, the total number of nucleosomes are
Hence, option C is correct
Answer:
of the answers i believe it to be B
Explanation:
The xylem can be found in either the roots or the leaves and they are dead tissue.
1) B- brown; b- red hair
Having brown hair is a dominant trait while red hair is recessive.
If the parents had a red-haired child it means they were carriers of the red hair trait, so their genotype is
Bb
2)Getting their genotypes together would result in the possibilities that you see at the image below.
1/4 = 25% BB - brown
2/4 = 50% Bb brown but carrier
1/4 = 25% bb red hair
Answer: 25%
3) The genotype of the child, as i said before would be
bb. By having both alleles being recessive the child will show red-hair. If it was any other genotype( BB or Bb), the child would have brown hair, like their parents.
When we mix sand and water, no reaction takes place. The sand simply settles down at the bottom of the water container. This is because sand is heavier than water and hence cannot float in water. ... In comparison, if we mix something like salt or sugar in water, they will react and make the water salty or sweet.
Option (B) Habituation is the right answer.
Crocodiles that ignore birds cleaning their teeth instead of eating them is an example of habituation.
<h3>Crocodile and avian mutualism—is it real?</h3>
- One of nature's best instances of mutualism is the interaction between a Nile crocodile and an Egyptian plover bird.
- A crocodile will simply open his mouth and wait when he needs to floss.
- The plover bird will involuntarily swoop down and grab meat scraps from the crocodile's gaping jaws.
<h3>Why do crocodiles develop a habit of approaching the birds that brush their teeth?</h3>
- It is a phenomenon of evolution that when a bird used to sit in a crocodile's mouth, the crocodile didn't eat it; instead, the crocodile used to allow the bird to sit in the mouth and clean the crocodile's teeth so that they can live longer, whereas the birds could get the free food from the crocodile's mouth.
- It is an illustration of how the two are mutually beneficial.
- The same is true now because crocodiles have adapted to the fact that birds will clean their teeth, so rather than consuming them, they ignore the birds.
