In Lesson 4.1, you learned that the machine used to fuel missions to Titan is not making enough liquid oxygen. We are waiting for a more detailed report from the Universal Space Agency. Before we receive the report, however—and now that you know how the liquid oxygen machine is supposed to work—what are some ideas you have about what could be causing it to malfunction? (I need about three sentences)
Answers
Answer:
Some ideas which could be causing it to malfunction is an increase in temperature of the titan.
What is Boiling point?
This is defined as the constant temperature at which a liquid starts changing into gas.
Liquid oxygen has a high boiling point which means the Titan will have to be hotter for it to vapourize. This may have led to an increase in the production of oxygen gas and reduction in liquid oxygen production.

As the water level inside the reactor vessels went low enough to expose at least the top core regions, a chemical reaction between water and the metal cladding of the fuel rods in the reactor cores is most likely what produced the hydrogen gas.
What causes hydrogen explosion?The escaping hydrogen self ignited, resulting in an explosion and flames. The explosive mixture of hydrogen and oxygen that spontaneously ignited inside the HP feed pipes was what caused the initial explosions.
What drawbacks exist with energy generated from hydrogen?But, hydrogen has serious safety hazards of its own. It is very combustible and has an ignition energy 20 times lower than that of gasoline or natural gas. Cell phones have the ability to ignite it.

An object is floating in the water, as shown in the picture below.
Describe the movement of the floating object as a wave passes by, and explain why the object is not carried forward with each wave.
Your answer should include at least two complete sentences.
Answers
Answer:
Balance Weight
Explanation:
The object has vertical weight with a floating device in it. When the waves hit the object in the water, they will go upward and then downward but stay in the original spot. This happens because the object uses the electromagnetic energy from the waves to not move with it.

these days cloths made out of a mixture of synthetic fiber and natural fibers are more popular than those made purly out of synthetic fiber. Discuss the reason for this
Answers
Answer: Clothes purely made of synthetic fibers are not comfortable in a hot and humid environment as they don't have the property to absorb water or sweat quickly so their water-resistant property makes them unsuitable for hot humid environment .
Explanation:
Mixing of synthetic fiber and natural fibers enhances the properties such as strength, elasticity, and ease of ironing and washing. Generally in hot environments it is preferred to wear a mixture of synthetic and natural fiber than wearing only clothes made from synthetic fiber .
Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing. Hence, these days clothes made out of a mixture of synthetic fibres and natural fibres are more popular than those made purely out of synthetic fibres.

Explanation:
In the following images, a blue circle represents an atom of one type of element, and a red square represents an atom of a second type of element. Determine which of them represent a pure substance, a homogenous mixture, and a heterogeneous mixture.
Are these in the right order?
Answers
Answer: No they are not. "Pure substance" is supposed to be placed in the middle picture. "Homogenous mixture" is supposed to be placed in the right picture. "Heterogenous mixture" is supposed to be placed in the left picture.
Explanation:
Pure Substances:
There are two categories of pure substances: elements and compounds (In our case, we have a compound).
Element (e.g. the blue circles or the red squares):
An element is a fundamental substance.An element cannot become simpler than itself, even if chemical separation methods are used.Compound (e.g. the blue circles bonded together with the red squares in the middle picture):
A compound is a substance made of two or more elements in fixed proportions (i.e. One element has the same amount as the other).A compound can be made into individual elements or simpler substances using chemical methods of separation.Mixtures:
There are two categories of mixtures: homo- and hetero- genous.
Homogenous mixture:
The substances or elements are mixed to look like one single substance and cannot be told apart (e.g. When salt dissolves in water, the water still looks like water).The substances or elements are distributed evenly throughout the apparatus. The number of different types of substances or elements can vary (e.g. There is more water than salt) The substances or elements do not bond together.Heterogenous mixture:
The substances or elements are mixed and can be told apart (e.g. When oil is mixed with water, the oil is "water-hating" so it forms its own layer on the bottom, while the water forms another layer on top of the oil layer).The substances or elements are distributed where one type of substance or element is bunched up in one spot and another substance or element in another spot.The number of different types of substances or elements can vary.The substances or elements do not bond togetherThe second Image is not a homogenous mixture, it is a heterogenous mixture as two different types of elements are mixed together.
The mix of two different types of elements in the heterogenous mixture is not uniform and has uneven mixed types.
The third image is a homogenous mixture as even though two different types of elements are together, they are not mixed with each other.
Unlike in the heterogenous mixture, in a homogenous mixture, there is a uniform mix of two different types of elements.
The first image is correct, the image depicts a pure substance.

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection
Answers
In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.
Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.
Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.
