Answer: none of the above
Explanation:
None of the above
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.
Answer: Structural chromosomal mutation
Explanation: In translocation, a small piece of chromosome is detached from one chromosome and is attached to another non-homologous chromosome. Translocation can be simple, shift or reciprocal.
Simple translocation involves single break in the chromosome. The broken piece gets attached to the end of the non-homologous chromosome.
In Shift translocation, the broken segment of one chromosome gets inserted interstitially in a non-homologous chromosome.
Segment from one chromosome is exchanged with a segment from another non-homologous chromosome simultaneously in Reciprocal translocation.
Answer:
Feathers initially evolved in a role associated with sexual selection.
Explanation:
In species where only males had feathers, these feathers can be considered to have evolved into a role associated with sexual selection. This is because in these species, males used their feathers as a sexual attraction for females, in this case, females chose the males that had more attractive feathers to mate and generate new individuals for the species. An example of this can be seen in the peacock, where the tail with lush feathers is only present in males and is intended to sexually attract females.
Answer:
Explanation:
Answer is: If the amount of snakes increased, the number of rabbits decreases.
A food chain refers to a linear arrangement of associations in a food web beginning from producer species and terminating at zenith predator species. In the given question, the increase of snakes population will eventually result in a decrease of rabbit population, a rabbit is a herbivore which is consumed by the higher predator snake.
