Answer:

''Stem cells makes copies of itself whereas differentiated cells can't.''

Explanation:

stem cells function differently from differentiated cells because the stem cells divide and make copies of itself. It has the potential either to remain a stem cell or become another type of cell such as a muscle cell, a red blood cell, or a brain cell if the body needed while on the other hand, differentiated cells are specialized cells which performs specific functions and unable to divide.

Answer:

Stem cells are unspecialized cells that can make copies of themselves without limits when needed whereas differentiated cells can't, instead they become specialized as their body develops.

Form a hypothesis about the relationship between vegetable mass and salinity of the solution
mihalych1998 [28]

Answer:

HYPOTHESIS: IF the salinity of the solution decreases, THEN the vegetable mass increases.

Explanation:

Hypothesis, in an experiment, is a testable explanation or prediction made to solve an observed problem or answer a question. It shows how one variable called independent variable affects another variable called dependent variable. It is usually written in the "IF, THEN" format.

In this case, the question states that there is a relationship between vegetable mass and salinity of the solution. This means that the question has been asked that "Why is the vegetable's mass affected by salinity of a solution". Hence, a hypothesis can read:

IF the salinity of the solution decreases, THEN the vegetable mass increases.

Which DNA fingering technique examines the length variation of DNA repeat sequences in human DNA?
DiKsa [7]

Answer: The question is incorrect, below is the correct question

Which DNA FINGERPRINTING technique examines the length variation of DNA repeat sequences in human DNA?

The correct answer to the question is option D

mtDNA (mitochondrial DNA) analysis

Explanation: DNA fingerprinting technique is a laboratory technique used by geneticists.it entails placing of DNA samples into wells,these wells are then placed in a slab of gels and thereafter passing a current through the gel.This is done to ascertain the uniqueness of a DNA pattern and thus be able to differentiate people of same species.

There are several methods of DNA fingerprinting as outlined in the options given with the question.

In mtDNA (mitochondrial DNA) analysis,The Genetic samples are extracted from the biological materials, these samples extracted are total genomic DNA like hair,tooth or samples of blood, Several copies of these genomic DNA are then produced using a polymerase chain reaction and flanking primers inorder to examines the length variation of DNA repeat sequences in human DNA.

4. A living cell is not a simple geometric shape, like a sphere or a cube. What sort of weird cell shape might increase the rati
Gnesinka [82]

Answer:

Gabriel's horn

Explanation:

What the question is asking for is a 3-dimensional shape that has a lot of surface area and only a little volume. The first thing I thought of was a geometric figure called Gabriel's Horn. A quick search on Wikipedia will explain better than I can, but basically it has infinite surface area but finite volume. You probably couldn't test the shape in any experiment, though, since it's only theoretical and can't exist in real life.

Let me know if I can explain anything in a clearer way!
