Answer:

39 chromosomes

Explanation:

A chicken is a sexually reproducing organism that undergoes meiosis to produce gametes. Meiosis is a type of cell division that involves the production of daughter cells (gametes) that have their chromosomal number reduced by half.

Hence, if the somatic or body cell of the chicken being ingested by Amanda contains 78 chromosomes, it will undergo meiosis to produce a sperm or egg that has 39 chromosomes i.e. reduced from diploid (2n) to haploid (n).

Answer:

39

Explanation:

Somatic or body cells are diploid and are denoted by 2n number of chromosomes. During meiosis, specifically after meiosis I in cell division, the chromosome number is reduced to half the number of that of the somatic cell, and is referred to as haploid, which is denoted by n number of chromosomes.

Therefore, if the somatic cell of the bird has 78 chromosomes, the sex cell (unfertilized egg or sperm) would contain half of the number of chromosomes of the somatic cell = 39 chromosomes.

Zinaida [17]

Answer:

I think the "your masticular (jaw) bone to your skull."

Explanation:

"Examples include the fibrous joints of the skull sutures and the cartilaginous epiphyseal plate. A joint that allows for limited movement is amphiarthrosis. An example is the pubic symphysis of the pelvis, the cartilaginous joint that strongly unites the right and left hip bones of the pelvis."

Put simply, an amphiarthroses joint is a joint with more limited movement.

your wrist to your fingers - very movable

your cranium to your spine. - pretty moveable

So that is why I think it is your masticular (jaw) bone to your skull! Hopefully this is correct and helps, have a nice day! :D

sergij07 [2.7K]

I'd appreciate if you attached the article as well. But i'm 90% sure it's option D. A quick search reveals that it was dubbed Black Saturday due to rapid fire growth within Yellowstone park. Option D is really the only one that relates to that at all.

Hope this helps!

How does extinction affect evolution?
Semenov [28]
If a species is said to be extinct, then that species is reduced to zero. There are none living in existence. The affects to other organisms of its extinction would depend on their value to the ecosystem. Regardless, extinction completely stops evolution of the species extinct.
