What is the significance of stem cells in the process of meiosis (i.e., what are they there for?)

Biology

rjkz [21]3 years ago

Well, certain stem cells are able to become any kind of (somatic) cell (totipotent stem cells), which helps in organ regeneration, etc. the only problem is that removing even one stem cell from an embryo kills the embryo, and people dont like that.

How does the mass of an object affect its a its acceleration during free fall
kirill115 [55]
Normally it is seen that objects with more mass accelerates during their free fall than objects having smaller mass. The frictional force of air also known as the drag force get negated by the massive object and so the object gets acceleration during the free fall. If the mass of the object is small, then the frictional force or the drag will slow the object during free fall. In case of vaccum the mass of the object does not matter as there is no drag or frictional force working against it. The objects with greater  or smaller mass will then free fall with the same speed in the vaccum.

In dna replication, the strands on the original molecule are used as blank______ for the synthesis of new dna strands.
Agata [3.3K]

The strands on the original DNA molecule serve as templates for the creation of new DNA strands during DNA replication.

<h3>What is DNA templates?</h3>

Because it includes the instructions a cell needs to survive, the genetic code is commonly referred to as a "blueprint." However, we now understand that these instructions are more complex than just the arrangement of the letters in the nucleotide code. For instance, copious evidence suggests that this code serves as the blueprint for the synthesis of numerous substances, including RNA and protein.

Additionally, studies have demonstrated that transcription and translation take place in order to "read" the DNA instructions that are stored there. A single-stranded RNA molecule is created during transcription from a piece of the double-stranded DNA template. In some instances, the RNA molecule is a "finished product" that performs a crucial task for the cell.

Which scientist showed that organisms do not grow spontaneously in beef broth?
QveST [7]

Answer:

Louis Pasteur.

Explanation:

Louis Pasteur gave theory of spontaneous generation that states, life arose from non-living things. Pasteur disprove the theory of spontaneous generation by S-shaped tube experiment.

He used swan-neck shaped flasks (twisted necks) and filled the flasks with sterilized beef broth.  Due to twisted neck, entry of air was allowed to the flasks from outside, but not microorganisms.

In these sterilized flasks, microorganisms could not grow as entry of airborne microbes was prevented. But if the necks of flasks were broken,  growth of microorganisms entered into flasks and showed growth.

Thus, Louis Pasteur showed that microorganisms do not grow spontaneously in flasks with beef broth.
