As the sample size increases, the t-distribution becomes more similar to the <u>normal</u> distribution.
<u>Option:</u> A
<u>Explanation:</u>
Student t-distribution is any member of a group or family of constant probability distributions that emerge in circumstances where the sample size is limited and the standard deviation of the population is unspecified when calculating the mean of a naturally distributed population.
The z-distribution implies you are conscious of the normal population deviation (never in case) when used for sample means. The t-distribution is focused on using the standard sample deviation as an approximation of the standard deviation in population.
The correct option is c. (20 m) .
As the formula to calculate wavelength is :
wavelength = wavespeed / frequency
Answer:
The Hardy Weinberg symbol for the dominant allele is 'p' in his equilibrium equation.
Explanation:
- The equation given by Hardy: "
" is known as "Hardy-Weinberg equilibrium equation". - The frequency of dominant allele and recessive allele for a trait is represented by 'p' and 'q' respectively.
- 2pq in the equation is the frequency for heterozygous genotype.
- Conditions that must be considered for the Hardy-Weinberg equilibrium equation to satisfy are: no mutations
, no flow of gene, large population size, no selective forces
, no non-random mating.
Answer: Amino acids are organic compounds (molecules) that contain amine (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid.
Explanation: The variation seen in naturally occurring amino acids arises from differences in this side chain.
Answer:
<em><u>The correct option is D) The two species have a common ancestor</u></em>
Explanation:
In evolutionary studies, homologous structures can be described as structures which are similar in organisms of different species because they had a common ancestor in the past. These structures may not perform the same function but are similar because they arose from a common ancestor. Hence, the bone in a bird's wing can be homologous to a bone in a lizard leg because they have a common ancestor in the past.
