Answer:
c. meiosis I and II results in two cell divisions
Answer: The correct answer is -
The phenotypic ratio for this cross is 3:1 ( short tail: long tail).
As per the information in the question, short tail of cat (depicted by T allele) is a dominant trait over long tails of cat (depicted by t allele), which is a recessive allele.
A dominant trait always masks the expression of recessive trait.
There can be two possible genotype for short tails, which are 'TT' and 'Tt'.
On the other hand, there is only one possible genotype for long tail, which is 'tt'.
Thus, from the given cross, we can conclude that the phenotypic ratio, representing the physical appearance of tail that is short and long tails is 3:1 (short tails: long tails).
All of the above statements describes scientific theory
Answer: Option D
<u>Explanation:</u>
A scientific theory is a clarification of a part of the characteristic world that can be more than once tried and confirmed as per the logical strategy, utilizing acknowledged conventions of perception, estimation, and assessment of results. Where potential, hypotheses are tried under controlled conditions in an examination.
In conditions not amiable to trial testing, speculations are assessed through standards of deductive thinking. Set up logical speculations have withstood thorough examination and epitomize logical information. The importance of the term scientific theory as utilized in the control science that is altogether unique in relation to the basic vernacular utilization of theory.
In ordinary discourse, the hypothesis can suggest a clarification that speaks to an unconfirmed and theoretical guess, while in science it depicts a clarification that has been tried and broadly acknowledged as substantial. These various utilization are practically identical to the contradicting uses of forecast in science versus basic discourse, where it signifies a simple expectation.
1. No conversions. The greatest advantage of SI is that it has only one<span> unit for each quantity ( a type of measurement). This means that it is never necessary to convert from one unit to another (within the system) and there are no conversion factors for students to memorize.
