Explain the differences between saturated and unsaturated lipids and give examples of each.
Answer:
The difference between saturated and unsaturated fat lies in the number of double bonds in the fatty acid chain. Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain.

Which property of minerals is the least reliable for identifying minerals?
hardness
luster
streak
color
Answer:
color.
Explanation:
Although color is the most obvious of mineral properties it is the least reliable for identification purposes. This is because the color of a mineral can be altered by slight chemical impurities within its crystal structure.
The color of a mineral is the least reliable for identifying minerals. Therefore, option D is correct.
What are the properties of minerals?A mineral species is identified by two distinct characteristics: its crystal structure and chemical composition. Each mineral has a unique three-dimensional arrangement of the atoms that make up its structure. Its physical characteristics, including cleavage and hardness, are impacted by its regular geometry.
Because they are composed of many elements, minerals have unique qualities. Iron, calcium, magnesium, silicon, carbon, phosphorus, oxygen, and many more naturally occurring elements can be found in minerals. Based on how many electrons each of these native elements have, they have various qualities.
The color of a mineral is the least reliable for identifying minerals. Therefore, option D is correct.

Based on the structures of each type, which cell do you think can perform more functions: Human cells or bacterial cells?
Answer: Human Cells
Explanation: Humans cells are composed of eukaryote cells. Each organelle in a eukaryote has a distinct function. Because of their complex level of organization, eukaryotic cells can carry out many more functions than prokaryotic cells. To summarize it is human cells.
write a mini-essay about Balanced & Unbalanced Forces
Answer:
Forces have a magnitude (strength) and a direction. Forces can be represented as arrows with the length of the arrow representing the magnitude of the force and the head of the arrow pointing in the direction of the force. Using such arrows, the resulting force (net force) and direction can be determined.
Forces acting on an object can be balanced or unbalanced.

What makes elements and compounds different from mixtures? Elements and compounds-
a). have a constant composition
b). are made of gases
c). will not change when heated
d). conduct electric current
Answer:
a). have a constant composition
Explanation:
Let's take water, a compound, as an example. Regardless of how much water you have, there will be one oxygen molecule every two hydrogen molecules. It has a constant composition. The same case is with elements. You'll have a constant amount of atoms per mole. Meanwhile, in mixtures, the composition of everything mixed together is not constant as it is not equal everytime.
Besides, the rest of the choices do not even make sense in the first place...
Biological control is used to control pests. Unfortunately there are risks involved if the biological control is a new species to the area. What are they?
Which of these best explains the impact of conduction on the atmosphere?
Water is heated up by the sun's energy.
Water heats up the air around it.
Dense air sinks closer to Earth.
Warm air rises upwards.

Which of the following is not true? *
A. Canadians are some of the highest users of resources and energy in the world.
B. The average person in the world has an ecological footprint of 2.2 hectares.
C. At the present rate, the world cannot sustain its present levels of using resources and energy.
D. The amount of resources used in North America is far less than those used in poorer countries.
Answer:
D
in poorer countries, they use much less energy resources
Answer:
I'm pretty sure it's choice D.
Explanation:
I believe it's choice D because in poorer countries, there are less resources to go around. Therefore it's near impossible to use more resources than used in North America
Before humans ever ventured into space, we fantasized about visiting—and even living on—other planets. As technology continues to develop, it may one day be possible for humans to call planets other than Earth's home. Space scientists have several possible Earth-like planets and moons insight, but one that is of high interest is Kepler-186f, a planet 500 light-years away. It orbits a star much like the Sun, and it orbits in a habitable zone: it is far enough from the star to allow for the pooling of water (if it is present) on the planet's surface.
Is being in a "habitable zone" enough to say the planet is habitable for human life? What characteristics would an Earth-like planet need to have to support life? What challenges would we face traveling to and colonizing Kepler-186f or other Earth-like planets outside of our solar system? Do you think scientists should spend time looking for Earth-like planets before we have the technology to visit them? Why or why not? PLEASE HELP ME!!! :((
Answer: yes because A habitable zone (HZ) in astronomy is a region of space where conditions are best for life to form as on Earth. Planets in these areas are the most likely to have extraterrestrial life. The habitable zone may also be called the "life zone", "comfort zone", "green belt" or "Goldilocks zone".

Why do animal cells not need the same structures vacuoles, cell walls and chloroplas, that plant cells need?
Answer:
Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don't get their sugar from eating food, so they need to make sugar from sunlight. ... Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.
