nucleosomes = 1.65 x 10^6

H2a = 3.3 x 10^6 molecules

H2b = 3.3 x 10^6 molecules

H3 = 3.3 x 10^6 molecules

H4 = 3.3 x 10^6 molecules

Explanation:

It was mentioned in the book Principles of Genetics  By D. Peter Snustad, Michael J. Simmons that in the nucleus of <em>D. melanogaster </em>there will be 1.65 x 10^6 nucleosomes and 3.3 x 10^6 molecules of every type of histone i.e. H2a, H2b, H3, and H4 present in it.

rjkz [21]

Answer:

The correct answer is option - 1. If passage through the placenta is adversely affected by fetal disease. and 4. If rapid drug effects are required.

Explanation:

Normally the drug that is provided and administrated to the fetal is through the placenta of the mother. The direct delivery of medicine can be dangerous. However, with the advancement of the medical technology direct fetal drug administration is possible and it assists in the rapid uptake of the drug by the fetus.

If the fetus requires a rapid drug effect it can be provided by direct drug delivery. Also when the placental is not working properly and affected by the disease it is recommended to provide the fetus with the drug with the help of direct delivery.

Thus, the correct answer is : 1. If passage through the placenta is adversely affected by fetal disease. and 4. If rapid drug effects are required.

<u>Distress vocalizations</u> can help this rescue dog and firefighters find fearful people and pets stuck in buildings that are on fire

Distress vocalizations are sounds produced in the presence of painful, stressful, or threatening stimuli.

Mammalian vocalizations are the product of respiratory and laryngeal activities under the direct control of brain stem cranial and spinal motor neurons and modulated by higher brain processes.

Vocalizations offer the further promise of unique informational content about the emotional state of the subject. There is evidence that the form, contexts, and neural processes which modulate distress vocalizations are highly conserved between species.
