Answer:
Mitochondria
Explanation:
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.
Superweeds: Due to new genetic engineering technology, scientists have been able to alter the DNA in corn, soybeans, and cotton to make them resistant to the chemical herbicides used to kill weeds. Consequently, millions of acres of United States farmland have been regularly sprayed with herbicides, leading to the development of a herbicide tolerance in weeds. Producers must now use larger amounts of herbicides and find new, stronger chemicals to fight off the herbicide-tolerant weeds.

why still humans have hair on body ?
Answer:
Hair is important for maintaining skin health, as each hair follicle has blood vessels, nerves, and fat around it. Hair follicles are rich in stem cells that promote healing of the skin — helpful if you have a cut or wound. Hair also keeps a person warm and protects the skin from sun damage.
Explanation:

Answer:
See below
Explanation:
Humans have hair on their bodies to prevent infections from entering the body. Lets take nose hair for example, while you breathe in and out threw your nose, any airborne virus may be caught and tangles in your nose hair, thus making it near impossible to enter your body, it is still possible though to enter the body.
Hair is important for maintaining skin health, as each hair follicle has blood vessels, nerves, and fat around it. Hair follicles are rich in stem cells that promote healing of the skin — helpful if you have a cut or wound. Hair also keeps a person warm and protects the skin from sun damage
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.

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.

examine the image shown here. These two species shown are pollinators and the flowering plant that they feed upon. Which statements accurately describe the interaction between these two groups?
A)Natural selection put pressures on the pollinator to increase its fitness over generations.
B)Heterozygote advantage provided a mechanism for species to become better fit for within their environment.
C)Convergent evolution caused the proboscis of the pollinator to mechanically fit with the flower of the other species.
D)The pollen of one species increased the mutation rate of the pollinator species so that they were more adapted to their flower.
E)Coevolution provided a mechanism for these two species to put selective pressures on each other to shape the pollinator structures.
Coevolution refers to the existing relationship between two species, and the selective pressures that each of them imposes on the other. These pressures result in both species evolving together in the same direction.
------------------------------------
When the interaction between two species is so strengthened that each population exerts a selective strength over the other one, simultaneous adjustments occur, resulting in Coevolution. Coevolution is the biological relationship existing between two or more species that interact and adapt to each other. Coevolution is the mechanism by which coadaptation can be explained. Coadaptation refers to reciprocal genetic changes in species that interact. This is due to the selective pressures that each of them imposes on the other. Coadaptation is what can be seen or observed.For coevolution to exist, there must be phenotypic variation and heritability. Coevolution can be specific or diffuse. Specific or strict coevolution involves two species in interaction in which the evolution of each one responds to selective pressures applied by the other species.
The correct option is E) Coevolution provided a mechanism for these two species to put selective pressures on each other to shape the pollinator structures.

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.

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.

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:
