Which one of the following statements about photophosphorylation is false?

Zepler [3.9K]

Answer:

C)The luminal side of the thylakoid membrane has a higher pH than the stromal side.

Explanation:

During the photophosphorylation, the electrons move through many electron carriers which allow the transport of hydrogen ions in the luminal side against the concentration gradient. This allows the increase in the Hydrogen ion concentration to the luminal side of thylakoid membrane and reduction in the hydrogen ion concentration of the stromal side.

Therefore due to the increased concentration of H⁺ ions in lumen during the photophosphorylation, the lumen has a lower pH than the stroma. During photophosphorylation, the pH of lumen decreases up to 4 and the pH of stroma increases up to 8. So the false option is C.

The graph above displays the heights of an average population of humans. Use C.E.R. (Claim, Evidence, Reasoning) to answer the f

sladkih [1.3K]

Answer:

The graph shows the height in inches of determined human population and the pattern it shows is due to the height variations that exist between individuals, due to different factors, where the average height in the population is close to 69 inches, and most of the population has heights between 67 and 72 inches.

Explanation:

The height of individuals is the measurement, from head to toe, which is made standing up and barefoot.

The graph shows the frequency of people who have a specific height, where:

Claim: According to the graph, most people are between 67 and 72 inches tall. Heights below 63 and above 72 inches are less frequent and the average person is about 69 inches tall.

Evidence: The data provided by the graph support the claim that there is variation in height in the human population. When data on anthropometric parameters are to be obtained, a sample is chosen, measured under the same conditions and then taken to a graph showing the results.

Reasoning: variations in human height respond to several factors, mainly genetic and environmental factors.

Inheritance plays an important role in determining an individual's height, although it is a polygenic pattern of inheritance, where multiple genes determine the height an individual will have.

In general, the height between men and women differs but, in addition, the inheritance of this parameter is linked to race. There is no single gene that determines whether a person will be tall or short, nor are there dominant or recessive alleles.

The combination of information from several genes will result in the phenotypic expression of height in an individual and can increases the genetic variability for this trait. It should also be taken into account that genetic disorders can affect the development of normal height.

Environmental factors and habits, especially food and family environment, are determinants of the height a particular individual will have.

Sense a dog has 78 chromosomes in their body cells and humans have 46, are dogs more complex than humans do to have a more chrom

Ksivusya [100]

Answer:

No

Explanation:

A carp (a kind of fish) has 104 and a rattlesnake fern has 184. Most likely neither of these is as complicated as we are (especially the fern).

These kinds of differences are out there because the number of chromosomes doesn’t have anything to do with how complicated or “advanced” a living thing is. What matters is what is on them.

Your fewer chromosomes have the set of instructions for making you and a potato’s chromosomes have the set of instructions for making a potato plant. It doesn’t matter how many pieces those instructions are cut up into.

Think about it like comparing the instructions for building a car to the instructions for building a bicycle.

Let’s say the car’s instructions are in one big book but the bicycle’s instructions are spread over five books. Making a bicycle isn’t more complicated than a car just because it is in five books instead of one. Same thing with your chromosomes and a potato’s chromosomes.

It also doesn’t always have to do with how many “pages” or even sets of instructions are in something’s chromosomes.

Ray Of Light [21]

Answer: origin.

The end of a muscle that is attached to the immovable bone is called the origin.

In some parts I have found that they refer origin of a muscle as the bone, while in other parts I have found that they refer tha origin is part of the muscle.

Anyway, the question is refering to this part: the origin of a muscle, which is a the end of a muscle that is attached an immovable or less movable bone.
