Answers
Explanation:
D is the correct answer. cuz this is how atos and carbon dioxide
The ball and stick model B represents a molecule of similar atomic composition to carbon dioxide.
What do you mean by the Ball and stick model?The ball and stick model may be defined as the pictorial representation and arrangement of atoms within the molecules with the help of spherical balls along with bonds.
Carbon has four electrons in its valence shells. So, it forms four single bonds with a bonded atom or two double bonds depending on the nature and electron of the bonded atoms.
Oxygen has six electrons in its outer shells and requires two more electrons to fulfill its octet.
Therefore, the ball and stick model B represents a molecule of similar atomic composition to carbon dioxide.

3. The human body has devised an excellent method to keep the body pH under control. a. What principle underlies the constant pH of human blood, and how does the blood achieve this
Answers
The normal blood pH for adult humans is 7.40, and this pH value is vigorously defended at normal body temperature
Acid base Homeostasis is the method by which body keeps a constant ph
pH is kept under check via different systems
1. Chemical system :bicarbonate buffer system(explained below )
Respiratory component :
2. Respiratory Component: The second line of dense is rapid consisting of the control the carbonic acid concentration in the ECF by changing the rate and depth of breathing by hyperventilation or hypoventilation. This blows off or retains carbon dioxide (and thus carbonic acid) in the blood plasma as required
3.Metabolic component : third line of defense is slow, best measured by the base excess,eand mostly depends on the renal system which can add or remove bicarbonate ions to or from the ECF.Bicarbonate ions are derived from metabolic carbon dioxide which is enzymatically converted to carbonic acid in the renal tubular cells.There, carbonic acid spontaneously dissociates into hydrogen ions and bicarbonate ions.When the pH in the ECF falls, hydrogen ions are excreted into urine, while bicarbonate ions are secreted into blood plasma, causing the plasma pH to rise.The converse happens if the pH in the ECF tends to rise: bicarbonate ions are then excreted into the urine and hydrogen ions into the blood plasma.
Buffers usually consist of a weak acid and its conjugate base; this enables them to readily absorb excess H+ or OH–, keeping the system’s pH within a narrow range.
Maintaining a constant blood pH is critical to a person’s well-being. The buffer that maintains the pH of human blood involves carbonic acid (H2CO3), bicarbonate ion (HCO3–), and carbon dioxide (CO2). When bicarbonate ions combine with free hydrogen ions and become carbonic acid, hydrogen ions are removed, moderating pH changes. Similarly, excess carbonic acid can be converted into carbon dioxide gas and exhaled through the lungs; this prevents too many free hydrogen ions from building up in the blood and dangerously reducing its pH; likewise, if too much OH– is introduced into the system, carbonic acid will combine with it to create bicarbonate, lowering the pH.
Example: Antacids, which combat excess stomach acid, are another example of buffers.

HELP ME PLZZZZZZZZZZZZ Clark decides to measure the volume of a rock he found outside. He fills a graduated cylinder with water to 30mL. Places the rock into the water and the water level rises to 37mL. What is the volume of the rock?
Answers
Answer:
The correct answer is - 7 cc or ml.
Explanation:
Given:
The volume of water in a graduated cylinder = 30 mL
The volume of rock = ?
Final volume = 37 ml
Formula:
If an object is placed in water, then the amount of water that is displaced or increased by submerging the object is equal to the volume of the object.
Vi + Vo = Vf
Vi = initial volume
Vo = volume of object
Vf = final volume
Solution:
Placing the values in formula -
30 + Vo = 37
Vo = 37 - 30
Vo = 7 ml or cc.

g Electron flow down the electron-transport chain leads to the transport of proteins: Group of answer choices from the matrix to the intermembrane space NONE OF THESE from the intermembrane space to the matrix from inside the mitochondria to the outside from outside the mitochondria to the inside
Answers
Answer:
from the intermembrane space to the matrix
Explanation:
In the electron transport chain (ETC), electrons flow from one protein complex to another. However, as this electrons are transfered, protons (H+) is built up from the intermembrane space of the mitochondria to the mitochondrial matrix.
Hence, according to this question, a proton gradient is formed when hydrogen ions (H+) are moving from the intermembrane space to the matrix of the mitochondrial.
The Galapagos Islands were formed from underwater volcanic activity. The islands initially were barren, supporting no life, and then they went through a series of colonization stages. The equilibrium model of island biogeography states that the species composition on an island will constitute a balance between the immigration and extinction rates. Based on the equilibrium model of island biogeography, indicate if the following statements concerning succession on the islands are predicted to be true or false.
a. Species arriving later might outcompete earlier arriving species, driving them to extinction.
b. The number of species on an island decreases as a function of the distance from the source-pool (in this case, mainland South America).
c. The number of immigrants will increase the closer the island is to the source.
d. The rate of extinction will be lower on smaller islands due to small population sizes and less competition.
Answers
Answer:
a. Species arriving later might outcompete earlier arriving species, driving them to extinction. (True)
b. The number of species on an island decreases as a function of the distance from the source-pool (in this case, mainland South America). (True)
c. The number of immigrants will increase the closer the island is to the source. (True)
d. The rate of extinction will be lower on smaller islands due to small population sizes and less competition. (False)
Explanation:
The equilibrium model of island biogeography, from the question, states that the species composition on an island will constitute a balance between the immigration and extinction rates.
The succession on the island would be how the species composition on an island develops gradually with time.
So, species arriving later might outcompete earlier arriving species. As the Islands continue to develop, major players like the primary producers and other factors that aid ecological development would support the growth of species that would previously have struggled to live on the island.
The number of species on an island can also be determined by the distance from the source-pool (in this case, mainland South America).
The more the island gets food from a near source, the more the influx of those organisms to the island.
So many factors contribute to extinction, some include, natural disasters, evolutionary changes, loss of habitat. Small population sizes and less competition do not mean a lower rate of extinction.

g In the mid-1800s, overhunting of Northern Elephant Seals reduced their population size to fewer than 40 individuals. However, the population has since rebounded to over 100,000 animals. The population went through a _________, which makes it more susceptible to ___________.
Answers
Answer:
In the mid-1800s, over-hunting of Northern Elephant Seals reduced their population size to fewer than 40 individuals. However, the population has since rebounded to over 100,000 animals. The population went through a _bottle neck event (genetic drift)_, which makes it more susceptible to _developing a genetic disease_.
Explanation:
Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time. Eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure-bottleneck effect- or because of a population split -founder effect- . The bottleneck effect most likely affects smaller populations.
In the exposed example, extensive hunting acted as a pressure that reduced the number of Northern elephant seals to fewer than 100. This population experienced one or many generations of small size since these animals were affected by hunting. As the survivors did not have the whole genetic pool of the original population, the population size might have recovered to a current population size of 100,000 individuals, but the genetic pool might have not. When the small population increases in size, it will have a genetically different composition from the original one. In these situations, there is a reduced genetic variability, with a possibility of developing a peculiar allelic component. If the survivors in the population carried or developed a mutation, probably this mutation passed from generation to generation. It will involve more individuals each time and increase the probability of developing a genetic disease.
