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.

ethical scientist would follow scientific method they would also report accurate data and they're going to keep detailed records now an ethical scientist is not going to hide their experiment from the public the only reason you're going to hide your experiment from the public would be because you have something to hide being on ethical and it would also be unethical to make an unbiased conclusion

Where do lipids, a class of organic compounds, fit on the hierarchy of biological organization? select the correct box?
Pavlova-9 [17]

Lipids are a class of organic compounds, which suits best under the column macromolecules on the hierarchy of biological organization.  

Biological organization refers to the hierarchy of composite biological systems and compositions, which illustrate life using a reductionistic method. The conventional hierarchy moves from an atom to more complex biospheres.  

Each of the level in the hierarchy signifies an enhancement in the organizational complexity, with each component being mainly comprised of the previous basic unit level.

How do I know the phenotype and genotype percentage on a punnet square?
Nesterboy [21]

Answer:

Phenotypes are physical attributes. Genotypes are the alleles.

The phenotypes are 75% green peas and 25% yellow peas. This is because the capital G is a dominant allele and green is the dominant attribute and as long as 1 G is present, then the pea will appear green.

The genotypes are 25% GG, 50% Gg, and 25% gg.

Please thank!
