HACTEHA [7]

Answer: a. endoderm-bone

Explanation: In the context of embryonic development, bone tissue may arise from several precursor cell populations, such as the neural crest (some facial bones), lateral mesoderm (bones of the limbs, among others), and paraxial mesoderm (vertebrae and part of the skull). There is no evidence to suggest that any of the bony structures is derived from the endoderm germ layer.

horsena [70]

Answer:

a.Many mitochondrial genes resemble proteobacteria genes, while the genes in the chloroplast resemble genes found in some photosynthetic bacteria.

c.Mitochondria and chloroplasts both have their own circular DNA and 70S ribosomes that are similar to those found in bacteria.

d.Mitochondria and chloroplasts replicate by a process similar to mitosis.

Explanation:

Endosymbiotic theory states that mitochondria and chloroplast which are organelles of eukaryotic cells were once independently living micro-organisms but with due course of time eukaryotic cells engulfed them and they become an integral part of these eukaryotic cells.

The resemblance between mitochondrial genes with those of proteobacteria and chloroplast genes with photosynthetic bacteria strongly support endosymbiotic theory. Apart from this, the presence of their own DNA that too circular just like prokaryotic microbes and 70 S ribosomes also support this theory. Also just like prokaryotic cells, before cell division mitochondria and chloroplasts undergo replication by means of a process known as binary fission.

In such a situation it would be best if Dr. Smith:

<span>''hire trained therapists who are from the same minority group''

This would have a wide ranging impact on the minority communities in the area.

Their participation would increase rapidly as their own community members would get the word out on the services provided and they might feel more comfortable in such an environment.

Since, mental health still has a stigma attached to it, especially in immigrant communities, this strategy would help to increase the level of mental health services provided to minority groups.
