In the shipyard, oxygen-deficient environments are the main reason for mortality in confined spaces and oxygen.

Thus, OSHA classifies any atmosphere with less than 19.5 percent oxygen as oxygen deficient, and any atmosphere with more than 22 percent oxygen as oxygen enriched. Normal atmosphere contains between 20.8 and 21 percent oxygen.

When inerting gases like carbon dioxide, nitrogen, argon, or the ship's inert gas system or firefighting system displace oxygen, oxygen-deficient atmospheres may result. Additionally, rusting metal, ripening fruit, drying paint or coatings, combustion, or bacterial activity can all use up oxygen.

There are some chemical processes that can result in oxygen-enriched atmospheres, but in a shipyard, leaks from oxygen hoses and torches are more common. Oxygen-enriched environments create serious fire and explosion hazards.

Thus, In the shipyard, oxygen-deficient environments are the main reason for mortality in confined spaces and oxygen.

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.

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.

Answers

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.
