1. Its particles move farther apart.

2. It is transferred to another substance (i.e. the air)

3. stick of butter- particles in a line and cannot move

melted butter- particles can slide by each other but are still close together

4. 0 degrees Celsius (32 degrees Fahrenheit)

5. evaporation- the surface of the liquid is heated slowly and eventually becomes a gas

boiling- the entire liquid is heated and the entire liquid becomes a gas

1. The particles keeps on moving (move faster) when a substances gains energy and changes state.

2. When water freezes it gives up some of the water's energy. This energy that is given up is the latent heat of freezing. When the water was freezing latent heat of freezing energy was being released. Heat energy was actually being released

3. In a stick of butter, the particles are locked together and are compact. In melted butter, the particles can slide past each other and are less compact.

4. 0 degrees Celsius.

5. Evaporation only happens at the surface while boiling happens all throughout.

Answer:

Hemostasis is the response that occurs when there is blood loss and the barrier of the skin has been compromised.

Explanation:

Hemostasis involves the process of blood clotting that ends in the formation of a clot, capable of stopping blood loss from an injury.

When a superficial wound occurs, there is an injury to the skin —with involvement of the dermal barrier— and the rupture of blood vessels produces bleeding. <u>Hemostasis helps to stop blood loss, so that wound healing and restoration of the skin barrier can begin</u>.

In humans, brown eye color (B) is dominant over blue eye color (b). A brown-eyed woman and a brown-eyed man mate and have a blue

Dmitry_Shevchenko [17]

Answer:

In the case of these two parents, a quarter of their children would have blue eyes.

Explanation:

It is not only possible, it is expected that this would happen an appreciable fraction of the time. Brown eyes are dominant. Suppose eye color were dependent on a single Mendelian gene with two alleles, Br for Brown eyes and Bl for Blue eyes. (As Tracey Bryan has explained, this is not true -- I want to explain what the answer would be even in the simple case.) This means the three possible combinations of two alleles give the following eye colors:

BrBr => Brown

BrBl => Brown

BlBl => Blue

Now suppose two brown-eyed people have a child. We can't tell from the fact that they have brown eyes which pairs of alleles they have. Each of them could have either BrBr or BrBl. Suppose they each have BrBl. When they are crossed (i.e., they have a child), the child gets one allele from its mother -- it has a 50-50 chance of getting either one -- and one allele from its father -- again it has a 50-50 chance of getting either one. So, the child has:

25% chance of getting Br from mother and Br from father => brown eyes;

25% chance of getting Br from mother and Bl from father => brown eyes;

25% chance of getting Bl from mother and Br from father => brown eyes;

25% chance of getting Bl from mother and Bl from father => blue eyes.

So in the case of these two parents, a quarter of their children would have blue eyes.

Cholangiocarcinoma (CC) is a highly lethal malignant tumor that arises from the biliary tract epithelium.

<h3>Abstract:</h3>

Background:

Cholangiocarcinoma (CC) oncogenesis and development are largely unknown molecular processes. The objective of this study was to map the expression of genes involved in CC oncogenesis and sarcomatous transdifferentiation across the entire genome.

Methods:

DNA microarray technology was used to find the genes that differed in expression between CC cell lines or tissues and cultivated normal biliary epithelial (NBE) cells. Expressions were verified in CC tissues and cells from humans.

Results:

We found a group of 342 genes that are often regulated (>2-fold change) in cell line and tissue samples using unsupervised hierarchical clustering technique. 289 of them, including tumour suppressor genes, were downregulated, while 53 of them, including genes connected to tumours, were elevated (0.5 fold change). Immunohistochemistry was used to confirm the expression of SPP1, EFNB2, E2F2, IRX3, PTTG1, PPAR, KRT17, UCHL1, IGFBP7, and SPARC proteins in human and hamster CC tissues. When sarcomatoid CC cells were compared to three adenocarcinomatous CC cell lines, additional unsupervised hierarchical clustering analysis found 292 differently upregulated genes (>4-fold change) and 267 differentially downregulated genes (0.25 fold change). Immunoblot analysis and immunohistochemistry labelling were used to confirm that 12 proteins were expressed in the CC cell lines. We discovered that during the sarcomatoid transdifferentiation of CC, the methylation-silenced proteins LDHB, BNIP3, UCHL1, and NPTX2 were restored, along with the expression of the proteins linked to the epithelial-mesenchymal transition (EMT), VIM and TWIST1.

In conclusion, identifying molecular targets for cholangiocarcinoma diagnosis and prognosis may be aided by the dysregulation of oncogenes, tumour suppressor genes, and methylation-related genes.
