Answer:

They can be harmful.

Explanation:

Prokaryotes are the organism that do not have nucleus and lacks the membrane bound organelle. Eukaryotes have well defined nucleus and contains the membrane bound organelle.

Th prokaryotes includes the small bacteria and other small organism. The bacteria can cause harmful disease in humans. They can cause cancer or can mutate the genetic constitution of the organisms. The prokaryotes can destroy the products that are harmful and their consumption can destroy the human health.

Thus, the correct answer is option (3).

Compare and contrast Prophase and Telophase. what is different about DNA of the chromosomes in these phases. ( Max 5 Sentences )
shepuryov [24]

Answer:

The C. elegans embryo is a powerful model system for studying the mechanics of metazoan cell division. Its primary advantage is that the architecture of the syncytial gonad makes it possible to use RNAi to generate oocytes whose cytoplasm is reproducibly (typically >95%) depleted of targeted essential gene products via a process that does not depend exclusively on intrinsic protein turnover. The depleted oocytes can then be analyzed as they attempt their first mitotic division following fertilization. Here we outline the characteristics that contribute to the usefulness of the C. elegans embryo for cell division studies. We provide a timeline for the first embryonic mitosis and highlight some of its key features. We also summarize some of the recent discoveries made using this system, particularly in the areas of nuclear envelope assembly/ dissassembly, centrosome dynamics, formation of the mitotic spindle, kinetochore assembly, chromosome segregation, and cytokinesis.

1. The C. elegans embryo as a system to study cell division

The C. elegans embryo is a powerful model system for studying the mechanics of metazoan cell division. Its primary advantage is that the syncytial gonad makes it possible to use RNA interference (RNAi) to generate oocytes whose cytoplasm is reproducibly (>95%) depleted of targeted essential gene products. Introduction of dsRNA rapidly catalyzes the destruction of the corresponding mRNA in many different systems. However, depletion of pre-existing protein is generally a slow process that depends on the half-life of the targeted protein. In contrast, in the C. elegans gonad, the protein present when the dsRNA is introduced is depleted by the continual packaging of maternal cytoplasm into oocytes (Figure 1). Since depletion relies on the rate of embryo production instead of protein half-life, the kinetics tend to be similar for different targets. By 36-48 hours after introduction of the dsRNA, newly formed oocytes are typically >95% depleted of the target protein.

Delvig [45]

Answer:

auditory cortex

Explanation:

Sensory information passes both the auditory and the limbic systems by the means of medial geniculate nucleus (MGN), a small oval mass that protrudes slightly from the underside of the thalamus, a big double-lobed structure buried under the cerebral cortex. Before the signal can travel on, however, it passes through another nearby structure called the thalamic reticular nucleus (TRN), which evaluates whether or not it should be passed on.
