Explanation:
Adult stem cells are best described as?
Explanation:
1 Definition. Adult stem cells are undifferentiated cells that reside among differentiated cells in a tissue or organ. They have the ability to renew themselves and differentiate into specialized cell types.
Adult stem cells, also known as tissue-specific stem cells or somatic stem cells, are multipotent cells that replace damaged and dying cells.
What are somatic stem cells?Somatic stem cells, also known as adult stem cells, are found in organs and tissues, have the ability to self-renew and give rise to the differentiated cell types that make up that organ or tissue (multipotency), and play an important role in the maintenance and repair of those organs and tissues. Adult stem cells are sometimes referred to as embryonic stem cells.
The bone marrow, the skin, the intestine, the brain, the blood vessels, the teeth, the reproductive system, and the heart are only some of the organs and systems in the body that include somatic stem cells.

1 Invasive plant species affect the interactions of living and nonliving components
of an ecosystem, so the removal of invasive plants is often necessary. The goal of
most plant-control methods is to disrupt or inhibit the function of different plant
systems. For example, insects can be used to chew through roots in order to
reduce a plant's ability to absorb water.
Which of these functions would be most immediately affected by a reduction in water
uptake by roots?
A Disease resistance
B Seed dispersal
C Sunlight absorption
D Photosynthesis
Answer: photosynthesis

How would a bacteria explore a non-coding portion of DNA?
Explanation:
Non-coding DNA sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional non-coding RNA molecules (e.g. transfer RNA, ribosomal RNA, and regulatory RNAs). Other functions of non-coding DNA include the transcriptional and translational regulation of protein-coding sequences, scaffold attachment regions, origins of DNA replication, centromeres and telomeres. Its RNA counterpart is non-coding RNA.
The amount of non-coding DNA varies greatly among species. Often, only a small percentage of the genome is responsible for coding proteins, but an increasing percentage is being shown to have regulatory functions. When there is much non-coding DNA, a large proportion appears to have no biological function, as predicted in the 1960s. Since that time, this non-functional portion has controversially been called "junk DNA".[1]
The international Encyclopedia of DNA Elements (ENCODE) project uncovered, by direct biochemical approaches, that at least 80% of human genomic DNA has biochemical activity, which they defined as being transcribed, a definition not shared with most other biologists.[2] Though this was not necessarily unexpected due to previous decades of research discovering many functional non-coding regions,[3][4] some scientists criticized the conclusion for conflating biochemical activity with biological function.[5][6][7][8][9] Estimates for the biologically functional fraction of the human genome based on comparative genomics range between 8 and 15%.[10][11][12] However, others have argued against relying solely on estimates from comparative genomics due to its limited scope.[citation needed] Non-coding DNA has been found to be involved in epigenetic activity and complex networks of genetic interactions and is being explored in evolutionary developmental biology.[4][11][13][14]

What functions do the fins have for the squid?
Answer:
Help Them Turn or Go faster
Explanation:
Normally the fins on a fish or whale are to help them turn but since squids are slow they might be for making them faster. I still think that they are for turning.
Answer:
Fins: At the tail (posterior) end of the squid students will notice the two fins on the mantle. The fins allow the squid to steer themselves, help stabilize their position and propel the squid at slow speeds.
