Answer:
Increases.
Explanation:
The pH of the intermembrane space increases as the poisoning of cyanide occurs. After cyanide poisoning, the electron transport chain can stop pumping of electrons into the intermembrane space. The pH of the intermembrane space would increase, the pH gradient would also decreases, and ATP synthesis would stop to occur. The pH of the intermembrane space is neutral i.e. 7 but due to cyanide it move towards basic.
Answer:
Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, the pH of the intermembrane space becomes more basic. The electron transport chain can no longer pump hydrogen ions into the intermembrane space and ATP synthesis stops.

Which type of cell adhesion is useful for anchoring cells together and defending against shear forces on tissues
Answer:
Desmosomes
Explanation:
Desmosomes are cellular structures that adhere to neighboring cells. Its function is to hold the epithelial cells together, associating the intermediate filament cytoskeletons of neighboring cells, thus forming a transcellular network with high resistance to mechanical traction. It thus allows the cells to maintain their shape and the epithelial sheet to exist in a stable form. Inside cells act as anchoring sites for intermediate rope-shaped filaments, which form a structural network in the cytoplasm providing a certain rigidity. Through these junctions the intermediate filaments of the adjacent cells are indirectly connected forming a continuous network that extends throughout the tissue.

Answer:
A. 100%.
Explanation:
Since both spiders have either AA or aa, every possible combination would result in an Aa genotype. And, because A is dominant to a, they will all display the A trait—be patterned instead of plain.
So it is 100%.
In a population of wild bees, a mutation resulted in slightly larger wingspan in some of the bees. This larger wingspan made the bees more efficient in their flights to flowers to collect nectar. Thus, these bees became more successful. This trait was passed on to offspring, and eventually the larger wingspan variety of bee replaced their smaller-winged relatives completely. It could be said that ____ favored the bee with the larger wingspan, and so the ____ evolved
Answer:
The correct answer is - natural selection, population.
Explanation:
In this case, the wild bees population experienced a mutation which helps in become more eeficient to fight for nector. This bees population is more sucessful to other that didnt recieved mutation and this mutation as it is adavtageous.
Natural selection always favored beneficial traits for the organisms to eveolved in generation therefore, these population is more succesful and replaced the short winged bees.

4. What is harder for the astronomer to measure: A galaxy's redshift (indicating recessional velocity) or its distance from Earth? Why? Explain your answer.
Answer:
Its distance from the Earth
Explanation:
Its distance from the Earth is more difficult to measure because to measure it we need the redshift anyways, or we can get a rough estimate by its brightness. To measure the redshift we just need its wavelength and some calculations.
Answer:
its distance from earth is harder
A common genetic mutation that lowers levels of the enzyme cathepsin C severely reduces a person’s ability to ward off periodontitis, or gum disease. The enzyme triggers immunological reactions that destroy diseased cells and eliminate infections
in the mouth. But researchers are developing ways to restore the enzyme to normal levels. Once that happens, we will be able to eliminate periodontitis.
Which one of the following is an assumption on which the argument depends?
(A) Restoring cathepsin C to normal levels is the only way to eliminate periodontitis.
(B) Genetic mutation is the only cause of lowered levels of cathepsin C.
(C) Researchers will soon succeed in finding means of restoring cathepsin C to normal levels.
(D) Persons who do not have the genetic mutation that lowers levels of cathepsin C do not get gum disease.
(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.
Answer:
(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.
Explanation:
Considering the fact that there may be some other causes of periodontitis aside from the lowered levels of the enzyme.
Therefore, should there be some other causes of periodontitis, hence, it can be concluded the process of restoring the enzyme to normal levels might not be sufficient for eliminating periodontitis.
Hence, the author's argument is solely based on this assumption, and option. Hence, option (E) is the correct answer.

Answer:
Its summer, winter, darker.
Explanation:
This is the answer I hope it helps you out.
Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.
What are seasons?A season exists the year that stands determined by particular climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly. Each includes its light, temperature, and weather designs that repeat yearly.
Summer exists the hottest of the four temperate seasons, happening after spring and before autumn. At or centered on the summer solstice, the earlier sunrise and latest sunset happen, daylight hours exist longest and dark hours exist shortest, with day length falling as the season progresses after the solstice.
Winter, the coldest season of the year, between autumn and spring; the name arrives from an old Germanic word that represents “time of water” and guides to the rain and snow of winter in middle and increased latitudes.
Hence, Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.

Answer:
It's Called Probability.
Explanation:
Cerebrospinal fluid (CSF) is formed by capillary knots called the ________________________, which hangs inside the ________________________ of the brain. Ordinarily, CSF flows from the lateral ventricles into the ____________ ventricle and then through the _______________ into the fourth ventricle. Some of the fluid continues down the ________________________ of the spinal cord, but most of it circulates into the ________________________ by passing through three tiny openings in the walls of the ________________________. As a rule, CSF is formed and drained back into the venous blood at the same rate. If its drainage is blocked, a condition called ________________________ occurs, which results in increased pressure on the brain.

You treat a sample of DNA with DNase and run the digested fragments out on an electrophoretic gel. You found mostly long fragments. What can you conclude about this sample of DNA
Answer:
the sample contains mostly heterochromatin
Explanation:
Heterochromatin refers to a highly condensed state of DNA, whereas euchromatin is lightly packed. It is for that reason that heterochromatin is associated with a transcriptionally inactive state, whereas euchromatin regions are active for transcription. Heterochromatin regions resist DNases because these enzymes don't cut DNA randomly, but they show sequence preference. In consequence, highly repetitive DNA heterochromatin regions (e.g., centromeres, telomeres, etc) may exhibit resistance to DNA cleavage.

Why has the number of people in the world increased if the human population growth rate has decreased?
Answer:
Life expectancy has steadily risen.
People live longer lives.
To understand the reasons why the number of people in the world has increased and the population growth rate has decreased, it is necessary to understand how the world's demographic growth rate is calculated.
The calculation is made from the balance between the total number of people alive and the total number of deaths that occurred in a period of time.
Therefore, we can understand that the population growth rate has decreased due to several relevant factors, such as:
Increased life expectancy.The decrease in infant mortality.Rising fertility rates.Urbanization.Economic development.These are some of the reasons that help us understand why population numbers increase and population growth rate decreases.
Economic development, new technologies and a better quality of life for the population are directly related to the decrease in the population growth rate.

While you and your little cousin are walking through a natural history museum, she points out the skull of an australopithecine with a large crest on the top and asks you what its purpose was. How might you correctly sum up this complicated evolutionary trait for your little cousin
Answer:
The purpose of the crest was to provide a surface for masticatory muscle attachment or insertion.
Explanation:
This crest is called the sagittal crest. It is present in extinct hominids, such as Australopithecus and Paranthropus, and can also be found in living animals such as gorillas or lions and some reptiles.
The sagittal crest is a bony structure that crosses the hominids´ skull longitudinally, and it is so well-developed that it stands out notoriously.
This crest, like others in the skulls, provides an attachment surface for many muscles. In the particular case of the sagittal crest, it is believed to provide an insertion area to mastication muscles.
It seems that Australopithecus had a special diet composed of tough items. The hominid probably needed to strong bite while eating. The strong jow muscles gave them the possibility to bite but needed a wide area for insertion. The sagittal crest provided that wide surface. There was a direct relationship between the size of the crest and the muscle mass. The bigger the crest was, the more developed the muscle was.
It is believed that in living animals, such as gorillas, the development of the crest in males is for sexual selection and reproductive success. The bigger the crest is, the more attractive the male is, and the more chances to be selected by the female to mate it will have. Some hypothesize that the development of the crest in Australopithecus could also be related to sexual selection.
Some of the smallest cells in the human body are red blood cells. They make up nearly half the volume of blood. A typical red blood cell is 8 µm across. The largest artery that blood flows through is the aorta, which is about 20 mm (2 cm) across. How many red blood cells would fit side-by-side across the aorta? Show your working.
Answer:
[tex]$1.6 \times 10^{-3}$[/tex]
Explanation:
Given data :
Size of a typical red blood cells = 8 µm
= 0.0008 cm
The size of the largest artery through which the blood flows, known as aorta
= 20 mm
= 2 cm
Thus the number of the red blood cells that would fit side by side across the aorta would be = 2 cm x 0.0008 cm
= [tex]$1.6 \times 10^{-3}$[/tex]
