<h2>Emperor penguins</h2>

Explanation:

  • Evaporative and convective is Right answer.
  • Fish and krill make up the main part of their eating routine alongside <em>squid and scavangers.</em> Like other penguin species, <em>Emperor Penguins </em>have an unpleasant and spiky tongue which causes them <em>when attempting to eat tricky fish.  </em>
  • It  is the biggest of 17 types of penguin at 1.15 m (45 in.) tall.
  • It is likewise the main creature to occupy the open ice of Antarctica throughout the winter.  
  • The penguin is the tallest and heaviest of all living penguin species.
  • A gathering of penguins is known as a province, a rookery or a Waddle, yet these terms are for a gathering of penguins ashore.
  • A group of  of penguins drifting in the sea is known as a  raft.

Where did the plant get the energy it needs to grow? What materials are needed for
NeTakaya

Answer:

It's simple really—plants get the materials they need to grow cheifly from air and water! Sunlight provides the energy plants need to convert water and carbon dioxide (CO2), a major component in air, to carbohydrates, such as sugars, in a process called photosynthesis. Hope this is what your looking for!

A gene is involved in promoting limb development in humans. The gene is initially weakly activated during the limb induction pha
Anna [14]

Answer:

1. If the gene is weakly activated, it likely lacks repressive histone modifications, but may also lack the presence of histone marks associated with strong transcriptional activation such as acetylation.

When the gene is strongly activated, it likely lacks repressive marks (such as H3K9me2/3 and H3K27me3 - both examples of repressive histone methylation) and might possess some activating histone acetylation marks, such as H3K4ac, and active histone methylation such as H3K4me3

<em>An aside: The pattern and presence of different histone modifications would depend on the gene, but based on the fact that it is a developmental gene, I would assume that H3K27me3 and H3K4me3 are at play (these are part of the Polycomb/Trithorax system)</em>

<em />

After limb growth is complete, the gene is turned off. Repressive histone methylation marks would be associated with this state, such as the aforementioned H3K9me2/3 or H3K27me3.

2. Histone modifications are tightly linked to genome organisation. Histone methylation marks associated with repression such as H3K27me3 and H3K9me3 are associated with compact chromatin structures, which restrict the access of transcriptional machinery and other positive regulators. Conversely, histone marks associated with gene activation are associated with a more permissive chromatin environment that facilitates the binding of factors associated with gene expression. In the case of histone acetylation, the acetyl mark directly removes the positive charge of chromatin, relaxing its interaction with negatively charged DNA.

3. If the inappropriate activation of this gene caused a cancerous tumor, this gene would be referred to as an oncogene (or a proto-oncogene for the term before it is inappropriately activated).

Typically, there are two classes of genes that lead to cancer: tumor-suppressor genes and oncogenes. Tumor suppressor genes lead to cancer when their protective activity is reduced or demolished, leading to the production of cancer cells. Oncogenes lead to cancer when they become over active. Oncogenes are often genes associated positively with growth and proliferation, consistent with the gene in this example.
