Help :) Two pigs with curly tails breed and have six offspring. One of the piglets has a straight tail. What is the most likely explanation for this?

That piglet has a different father than the others.
A genetic mutation occurred in the gamete.
Something the mother pig ate during pregnancy caused it.
Mitosis occurred with more than one division cycle.

Answer 1
The most likely explanation for the piglet having a straight tail is that a genetic mutation occurred in the gamete.

Inherited traits, such as tail shape, are typically determined by genes passed down from the parents to their offspring. If both parent pigs have curly tails, it suggests that curly tail is the dominant trait in their genetic makeup. However, occasionally, genetic mutations can occur spontaneously, resulting in a change in the genetic information. These mutations can alter the expression of traits, leading to variations in the offspring.

In this case, it is likely that a genetic mutation occurred in the gamete (sperm or egg cell) of either the mother or the father pig, resulting in the piglet having a straight tail instead of the curly tail inherited from its parents. This mutation could have affected the genes responsible for tail shape, causing a deviation from the expected phenotype.

The other options mentioned—having a different father, the mother's diet during pregnancy, or multiple divisions in mitosis—do not typically explain the occurrence of a trait that deviates from the parents' traits in the same generation. Genetic mutations are a more plausible explanation for such variations in inherited traits.

The following code simulates the movement of a golf ball in the air after it's been hit. initialVelocity ← 44 accelFromGravity ← -9.8 x ← 0 y ← 0 t ← 0 REPEAT UNTIL (y < 0) { x ← initialVelocity * t; y ← (initialVelocity * t) + ((accelFromGravity * (t*t)) / 2) DISPLAY(x) DISPLAY(y) t ← t + 1 } Which statement best describes why this simulation is an abstraction?

Answers

Answer:

It leaves out details that do not effect the results as much, such as air resistance or golf ball material.

Explanation:

A simulation is an abstraction of a complex phenomena that captures the higher-level details that are necessary for the purposes of the simulation and excludes other details.

Imagine you are interested in finding out how much time it takes on average to walk from one end of your school to the next. You’ve decided to figure this out on your lunch break and are able to complete the walk 20 times what would your algorithm look like where could a loop show up? Note: you do not have to write your algorithm in a programming language. You can write it out in English or in pseudocode code

Start a timer at one end of the school.

Walk at a normal pace to the other end of the school while timing the walk with the timer.

Stop the timer once you reach the other end of the school.

Record the time taken to walk from one end of the school to the other.

Repeat steps 1-4 twenty times.

Calculate the average time taken by adding up the recorded times and dividing by 20.

A loop could show up in step 5, where the process of walking from one end of the school to the other and recording the time is repeated 20 times. This could be accomplished using a for loop in a programming language, where the loop would run 20 times, with each iteration representing a walk from one end of the school to the other.
