Both pluripotent and totipotent cells are part of the stem cells. The stem cells have an ability to transform themselves into many type of cells that makes up the body.
During the mitosis of the zygote, 2 identical cells are formed. Those cells will form other cells and finally develop an organism. Those are the totipotent cells. Now to become a foetus, the baby undergoes a stage in which he's called an embryo and other cells develop: the pluripotent cells, which are able to become any cell that forms the body and help the embryo become a foetus.
So the difference between totipotent and pluripotent cells is that totipotent cells can only develop the organism, forming the embryo and the protective placenta, while the pluripotent cells can become any cell present in the body and help the embryo to become a foetus.
Hope this helps! :)
B) identifying the minerals within it.
C) studying how it has been affected by erosion.
D) comparing the size of one layer with other layers.
Answer; Radiometric dating
Explanation:How do scientists determine the ages of the rock layers?
The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample. Radioactive isotopes break down in a predictable amount of time, enabling geologists to determine the age of a sample using equipment like this thermal ionization mass spectrometer.
The addition of another person at each end of the rope does not affect the results of the tug of war.
The addition of another man at each end of the rope does not affect the results of the tug of war because the forces exerted by each individual are independent of each other.
In a tug of war, the force applied by each person depends on their individual strength and the technique used to pull the rope.
The total force exerted on the rope is the sum of the individual forces, and it remains the same regardless of the number of people at each end.
Answer:
1. Incomplete dominance has occurred
2. A phenotypic ratio 1 Blue : 2 pale blue : 1 white will be obtained.
Explanation:
Mendelian principle states that one allele is capable of masking the expression of another i.e. one allele is dominant and the other one is recessive. Genetic scenarios that have gone against this principle has been observed. One of them is the concept of INCOMPLETE DOMINANCE, which is a case where one allele is not completely dominant over the other, hence, they combine to form a third intermediate phenotype different from both parents.
This is the case in the question where the the blue allele (B) fails to completely dominate the white allele (W), instead it forms an heterozygous plant (BW) with a different phenotype (pale blue) that is a blending of the two parental phenotypes (blue and white). This heterozygote (BW) is formed in the F1 generation.
If the F1 offsprings (BW) are self-crossed, four possible offsprings will be produced using a punnet square. This offsprings will have genotypes: BB, BW, BW, and WW. This depicts a genotypic and phenotypic ratio of 1:2:1 i.e. 1 blue (BB) : 2 pale blue (BW) : 1 white (WW).
In science, a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors. A theory is always backed by evidence; a hypothesis is only a suggested possible outcome, and is testable and falsifiable. ... Scientific laws explain things, but they do not describe them.
A scientific hypothesis is a preliminary, testable prediction about a phenomenon, while a scientific theory is a comprehensive and well-substantiated explanation supported by a large body of evidence. Theories are formed when hypotheses have been extensively tested and confirmed.
A Scientific Hypothesis and a Scientific Theory are fundamental aspects of the scientific method, but they serve different purposes. A Scientific Hypothesis is a tentative explanation or prediction about a phenomenon or set of observations. Hypotheses are formulated based on limited evidence and are testable through experiments and observations. They act as a starting point for scientific investigations.
On the other hand, a Scientific Theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of facts that have been repeatedly confirmed through experimentation and observation. Theories are more comprehensive than hypotheses and are backed by a significant body of empirical evidence. They are widely accepted in the scientific community because they have been rigorously tested and validated.
In essence, a hypothesis can be considered as an initial, testable explanation, whereas a theory is the culmination of the testing process, put forward only when a hypothesis is confirmed by substantial empirical evidence.
