Lucille was finding it difficult to play soccer after school. Her doctor tested her cells and found that they contained low levels of oxygen. When Lucille shared these results with a friend, her friend said there might be a problem with Lucille’s respiratory system.
What do Lucille’s cells need in order for her body to function properly? How might a problem with Lucille’s respiratory system lead to low levels of oxygen in her cells? Why does having low levels of oxygen in her cells make it difficult for Lucille to play soccer?
Answer:
The Lucille’s cells need Oxygen and glucose in order to function her body properly.
Explanation:
Our body breakdown the glucose using oxygen in order to produce energy.
By respiratory system we inhale oxygen and
By digestive system we digest food into glucose.
Our circulatory system transfer the Glucose and Oxygen to the all cells of our body,
Hence we can conclude that the Lucille’s cells need Oxygen and glucose in order to function her body properly.
When we ingest large molecules, they must undergo several processes before they may be completely digested. One of these processes uses both skeletal and smooth muscle contractions. This is called _____________. A. Absorption B. Secretion C. Chemicaldigestion D. Mechanical digestion
When we ingest large molecules, they must undergo several processes before they may be completely digested. One of these processes uses both skeletal and smooth muscle contractions. This is called mechanical digestion (option D)
Digestion is the process by which food
molecules is broken down into smaller particles.
This also takes two forms one of which is chemical digestion and the other: mechanical digestion.
Mechanical digestion involves the physical aspect of digestion which may include churning in the mouth, contraction of the smooth muscle etc.
All this is to break the food down into smaller particles. Chemical digestion is done with the aid of enzymes to help break large food particles down

In between the two main groups of planets of the solar system, there is a vast belt of billions of asteroids. What are these asteroids mostly made of?
Answer:
Rocks of varying sizes.
Explanation:
Billions of asteroids between two main groups of planets in the solar system are rocks of various sizes.
What are asteroids?The solar system's asteroid belt is a torus-shaped area about halfway between Jupiter and Mars orbits. It has a large number of asteroids or minor planets.
Which are solid bodies with erratic shapes and sizes that are smaller than planets. It seems that one or more planets may have developed in the zone between Mars and Jupiter, but Jupiter's gravity kept tearing everything apart.
The material in this area was never able to create a single planet, just asteroid-sized particles.
Therefore due to various solid particles between the two main planets, there is a belt of asteroids.

Why is DNA found in both the nucleus and in the mitochondria? What is the advantage of
doing this?
AnswerAll multi-cellular life forms have them. In some organisms the DNA that codes for the mitochondrion has been moved into the nucleus and become part of the DNA of the host cell, but in vertebrates the mitochondria keep their own DNA inside themselves.
Explanation:
Answer:
Mitochondria are found in all eukaryote organisms, unlike prokaryotes. Both nucleus and mitochondria have their own DNA. The DNA of mitochondria is called mitochondrial DNA. The mitochondrial DNA helps in the production of ATP that produces energy whereas the DNA in the nucleus is the genetic material of the cell.
Explanation:
The presence of DNA inside the mitochondria is because of the fact that mitochondria are believed to be a primitive bacterium that was consumed by a eukaryote and became an essential organelle of the eukaryotic cell. Today, mitochondria exist only inside a eukaryotic cell serving as the powerhouse of the cell and containing mitochondrial DNA containing 37 genes. Advantaged of DNA in both nucleus and mitochondria:Advantages of DNA found in mitochondria and nucleus are: 13 genes of mtDNA perform the function of oxidative phosphorylation.Other genes help in the formation of tRNA and ribosomes which helps in efficient protein synthesis and production of ATP.The presence of a high number of mtDNA in the cell helps in producing a great amount of energy for the functioning of the cell.For more information:

While humans have developed clothing and other means of keeping warm, the hair found on the head serves primarily as a source of heat insulation and cooling (when sweat evaporates from soaked hair) as well as protection from ultra-violet radiation exposure. The function of hair in other locations is debated.

You are able to extract mitochondria from the cell and remove the outer membrane. You want to show that the mitochondria can still produce ATP if placed in the right solution. The solution should be isotonic, but at what pH
Answer:
Low PH
Explanation:
The high external acid concentration causes an increase in H+ in the inter membrane space leading to increased ATP production by ATP synthetase.
Mitochondrial production of ATP requires a concentration gradient of H+, with a high concentration at the inter membrane space and a low concentration in the matrix. The inner membrane is impermeable to H+, but the outer membrane of the mitochondria will allow H+ to pass through. Thus, placing mitochondria in a low pH buffer produces a H+ gradient that can generate ATP through ATP synthetase.

In the context of the thesis supporting the tragedy of the commons, what does the word "finite" mean? A. We can draw from a resource forever, regardless of how much we use B. Resources last forever C. Resources last for a very, very long time D. Resources do NOT last forever
Answer: D
Explanation: Finite means that there is not an infinite amount of something, and therefore does not last forever.
In the context of the thesis supporting the tragedy of the commons, the word "finite" means that the resources do not last forever. Thus, the correct option is D.
What is the tragedy of the commons?The tragedy of the commons refers to a situation in which the individuals with access to a public resource which is also called as a common act in their own interest and, in doing so, these ultimately deplete the resource in the given environment.
A non-renewable resource is also called as a finite resource is a natural resource which cannot be readily replaced by the natural means at a pace that is quick enough to keep up with their consumption. An example is the carbon-based fossil fuel. The original organic matter, with the aid of heat and pressure, becomes a fuel such as the oil or gas molecule.
Therefore, the correct option is D.

Imprinting
Insight
Animals right after birth or hatching engage in a sort of intrinsic learning called imprinting . Baby geese, a human, is an example of imprinting. Therefore, option C is correct.
What is imprinting ?An animal's imprinting refers to a crucial early stage of its life when it builds attachments and creates a sense of its own identity. Mammals and birds have a pre-programmed urge to imprint on their mothers from birth.
Animals right after birth or hatching engage in a sort of intrinsic learning called imprinting to recognize their caregiver for care, food, and protection. As a result, they can grow behavioral patterns that are unique to their species for socializing, mating, and surviving.
In order to continue its evolutionary survival, the child recognizes its mother through oral tactile memory throughout the imprinting and following latching stages of emotional and neurobehavioral development.
Thus, option C is correct.

In 3–5 sentences, explain why electrical wires are often constructed from metal coated with rubber, and how that is similar to metal pans having rubber or plastic handles.
Answer:
Electrical wires are often constructed from metal coated with rubber to act as insulator. Metal pans have rubber or plastic handles as insulator. Thus, with insulator, we can prevent from getting electrical shock when we touch the wire.
Electrical wires are often constructed from metal coated with rubber because it provides the wires with a specific property known as Insulation.
What is the composition of electrical wire?Electrical wires are made up of metals like copper and aluminum. But apart from these, they are generally coated with rubber in order to make them an insulating agent. These coated rubbers are poor conductors of heat and electricity.
The same mechanism is applied in the construction of metal pans that have rubber or plastic handles as well. This is because being poor conductors of heat and electricity, rubber or plastic is ideal for holding an object which is completely made up of metals.
Therefore, due to possessing a property of insulation, rubber or plastic is often used in the coating of electrical wires and holding metal pans.
