A stem cell is an undifferentiated cell that can differentiate into several types of specialised cells and can self-renew through cell division in the context of cell differentiation. The therapeutic potential of stem cells in regenerative medicine is based on their capacity to differentiate into a wide variety of cell types in the body.
Adult stem cells and embryonic stem cells are the two primary categories of stem cells. Embryonic stem cells can differentiate into any form of cell in the body and are derived from embryos. Adult stem cells, on the other hand, are more constrained in their capacity to differentiate into distinct cell types and can be found in a variety of tissues throughout the body. The growth, development, and repair of the body's tissues and organs depend heavily on stem cells.

A stem cell is an undifferentiated cell that can perform cell division.
Stem cells are unique cells that have the ability to differentiate into various specialized cell types in the body, such as nerve cells, muscle cells, and blood cells. They are characterized by their ability to divide and renew themselves over long periods, giving rise to more specialized cells. Stem cells can be found in embryos, as well as in adult tissues such as bone marrow, skin, and the brain. Stem cells have enormous potential for treating a range of diseases and injuries, as they can be used to replace damaged or diseased cells and tissues. Researchers are working to better understand the properties and behavior of stem cells, and to develop new therapies based on this knowledge.

The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.
Explanation:
In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.

How does an organism obtain CO2, H2O, and energy
to undergo photosynthesis?
Answer:
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
Explanation:
By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2).

explain how the structure of ATP relates to its function
Answer:
ATP functions as the energy currency for cells. ... The structure of ATP is that of an RNA nucleotide with three phosphates attached. As ATP is used for energy, a phosphate group or two are detached, and either ADP or AMP is produced. Energy derived from glucose catabolism is used to convert ADP into ATP.

The current taxonomic system is based on the Linnaean classification system.
All of the current, living species in the world have been cataloged.
Answer:
1) taxonomy
2) species
3) the animal has sharp, pointed teeth
4) the current taxonomic system is based on the Linnaean system
5) he only had two kingdoms, animals and plants
Explanation:
did the quich check
The statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.
Taxonomy is a field of study focused on naming and classifying groups of organisms according to their morphological and genetic features. The taxonomic system organizes species from larger to more specific taxonomic categories in a hierarchical system.The botanical taxonomist Carolus Linnaeus is considered the father of taxonomy because he was the first person to formulate a system for classifying different species of plants and animals.Nowadays, the taxonomic system includes eight (8) categories from larger to more specific: domain, kingdom, phylum, class, order, family, genus, and species.In conclusion, the statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.

The illustration is a representation of multiple gene alleles on the same chromosome. One inherited trait linked to alleles "A", "a", "D", "D", "t", and "T" is determined by __________.
Answer:
A characteristic linked to the alleles that is inherited is the genotype.
Explanation:
The genotype is the genetic makeup of an individual. The genotype is determined by the alleles and is passed from father to son through the transmission of alleles, that is, the genotype is an inheritable characteristic. The genotype cannot be modified by the environment, nor can it be modified in a natural way, but it can be modified through mutations that are also inheritable.

Explanation:
Why would cells from the same organism have different functions?
Answer:
Explanation: Cells have to fulfill multiple different functions to be able to build complex multicellular organisms. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. ... When this factor cannot be expressed, these cells do not develop at all.
If a gene has two alleles, there are two possible genotypes.
a. True
b. False
Answer:
b. False
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
According to Mendel's Law of Dominance, if a gene has two alleles, there are three (3) possible genotypes.

III. A recessive combination such as aa.
Where;
