Answer:

If an individual Drosophila has two or more populations of cells comprising different genotypes from one single egg then it is termed as twin spots or mosaic.

Explanation:

There might be different reasons for mosaic to occur like

Nondisjunctioning of the chromosomes

Lag in anaphase

Endoreplication

Mutations in a single cell

Mitotic recombination:

One of the major ways through which mosaic or twin spots arise is the mitotic recombination. It is also termed as somatic cross over. Twin spot or mosaic generally occurs if there is linking of heterozygous genes in repulsion. The recombination generally happens among the centromeres from the adjacent genes.

A common example of the mitotic recombination is the Bloom's syndrome. Bloom's syndrome is caused due to the mutation that occurs in the <em>blm</em> gene. As a result, there are defects in the BLM protein produced.

Answer:

c. lobes  

Explanation:

Brain lobes are divisions of the cerebral hemispheres, designated by the names of the surrounding cranial bones and covering them. The frontal lobe is located in the forehead region; the occipital lobe in the nape region; the parietal lobe in the upper central part of the head; and the temporal lobes in the lateral regions of the head above the ears.

Parietal, temporal and occipital lobes are involved in producing the perceptions resulting from what our sensory organs detect in the outer environment and the information they provide about the position and relationship to outer objects of different parts of our body.

The correct answer is a theory.  

A theory is a rational and contemplative kind of generalizing or abstract thinking or the outcomes of such thinking. On the basis of the context, the outcomes might involve generalized illustrations of how nature functions.  

A theory can be a source of knowledge that may or may not is related to the specific explanatory models. To theorize is to create the body of knowledge.

Ahat [919]

Answer:

Shoulder dystocia

Explanation:

  • If during the vaginal cephalic delivery, there is a requirement of additional obstetric maneuvers after the head of the fetus has been delivered however the gentle traction is failed then this condition is known as shoulder dystocia.
  • Shoulder dystocia occurs when the shoulder of the baby gets stuck in the pubic bone of the mother after the head has been delivered due to which the baby retracts his head back into the birth canal.
  • Gestational diabetes is one of the conditions that impose a risk on the baby to have shoulder dystocia during the delivery.
  • Since in the given question it is mentioned that the mother has gestational diabetes and the head has been delivered but seems to retract back, this points out that the condition suspected is shoulder dystocia.
