Stem cell and cancer question. Please answer Asap!!
malfutka [58]

Metastasis will happen and cancer cells invade nearby healthy cells, tissues, lymph nodes, organs or will migrate to distant organs.

The two different types of stem cells broadly classified as  are Embryonic stem cells and adult stem cells. Embryonic stem cells are obtained from the blastocyst layer of the embryo and are pleuripotent. Whereas adult stem cells are the undifferentiated cells from tissues of an adult or a child. They can be unipotent or multipotent.

Explanation:

Cancer cells migrate to other parts of the body via blood and lymphatic system. This is called as metastasis. Cancer cells when becomes tumour they develop their own blood vessels and obtain nutrients from them. Once the tumour gets big it pushes the normal healthy cells of the neighbouring tissues and keeps on spreading.

Stem cells obtained from the embryo can differentiate into any types of cell and when grown in-vitro can dramatically form the three germ layers.

The adult embryo cells are found in less quantity, their role is to repair the tissue they reside in.

A eukaryotic mutation upstream of a particular gene has been identified that changes the sequence of the TATA box to GATA. How w
Allushta [10]

Answer:

Transcription factor binding would be reduced or eliminated, and transcription of the gene would decrease dramatically.

Explanation:

Mutation means the changing of the structure of the gene that results in the variant form which may be transmitted to the subsequent generations.  They are caused by the altering the the single base units in the DNA of the species.

In both eukaryotic as well as prokaryotic, the mutation can affect the diversity in the future generation of the cells.

The eukaryotic mutation of the gene affects the transcription of the gene as the transcription factor binding will be lowered or will be eliminated and the transcription of this gene will decrease.

If an underwater volcano bubbled additional co2 into the ocean, would this sequence of reactions be driven to the left or the ri
galina1969 [7]

Answer;

-The reactions will be driven to the right

Explanation;

Volcanic eruptions are known to throw huge amounts of gas into the atmosphere, including carbon dioxide that are thought to increase global warming.

They spew lava, carbon dioxide and other elements into the deep oceans. The carbon gets trapped in circulating water, cycled to different regions of the ocean, where it gets caught up in upwelling currents and emitted to the atmosphere.The process can take up to 2,000 years and adds a fraction of the 88 million metric tons of carbon belched out by the volcanoes to the atmosphere.

Hi everyone
professor190 [17]

Amino acids are acids on one hand, and a base on the other hand.

<h3>What is an acid?</h3>

An acid is a substance that produces hydrogen or hydroxonium ions as the only positively charged ion when it ionizes.

All amino acids have an amine group -NH_2 and a carboxylic group -COOH.

The carboxylic group ionizes such that:

COOH -- > COO^- + H^+

The presence of the amine group enables amino acids to also act as a base.
