Answer:

Bird irruption and climatic phenomena subsequently

Explanation:

The Hawaiian islands are extremely diverse in both flora and fauna species. Today, similarly to the Galapagos Islands, there are thousands of species of Hawaiian finches, some of them eat seeds, others fruit, while other nectar, etc. Also, their beaks and colors are incredibly variable.

After years of research, scientists determined that it was one finch progenitor that arrived from Asia to the Hawaiian Islands around 6 million years ago, which gave rise to this process of speciation. This situation, as suggested by the researchers, occured due to a phenomenon known as 'irruption', characterized by the movement of hundreds to thousands of birds from one region to another located very far.

This finch is suggested to have gotten carried away in a storm, which eventually brought it to the Hawaiian Islands.

HACTEHA [7]

Single-cell RNA-sequencing (scRNA-seq) provides the chance to analyze heterogeneous cellular compositions and probe the patterns of gene expression that are unique to each cell type under various circumstances. However, batch effects like lab setups and individual variability make it difficult to use them in cross-condition designs.

<h3>What is Single-cell transcriptomes ?</h3>

In single-cell transcriptomics, the messenger RNA levels of hundreds to thousands of genes are simultaneously measured to assess the degree of gene expression in individual cells within a particular population.

<h3>Advantages : </h3>

• Integrated protocol proceeds directly from whole cells and preserves sample integrity.

• High resolution analysis enables discovery of cellular differences typically hidden by bulk sampling methods.

• Robust transcriptome analysis down to single-cell input levels for high-quality samples.

Answer:

The answer is A.

Explanation:

Found it on cancer.gov

Cancerous tumors are malignant, which means they can spread into, or invade, nearby tissues. In addition, as these tumors grow, some cancer cells can break off and travel to distant places in the body through the blood or the lymph system and form new tumors far from the original tumor

What’s this animal (picture is tagged) and where is it most likely to live, rainforest or desert?

lora16 [44]

I would guess rainforest because it’s an reptile/amphibian it appears and those animals need water to survive. There isn’t much water in the dessert.

Black lung disease was a common illness among coal miners in the 1950s, but it is almost unheard of in miners today.
