Answer:
Explanation:
After the gated channels close, which is as a result of depolarization of voltage, the positive charge that has been increased in the cell will make the potassium channels to open and this will gush out of the cell through its electrochemical gradients. When potassium ion move out of the cell, the membrane potential begin to get to resting potential.

Answer:
Dehydration Synthesis
Explanation:
DEHYDRATION (chemical), a chemical process consisting of taking away one or more molecules of water by some chemical connection. The process opposite to dehydration is hydration, ie. the addition of one or more water molecules to a chemical compound. Dehydration produces unsaturated compounds, such as olefins, ketones, and nitriles.

What is the relationship between the distribution of coral polyps and the population
density of plankton in the water?
a. Coral polyp distribution is independent of plankton density because they live in different geographical locations.
b. If there is a high density of plankton in the water, then there will be a high coral polyp distribution.
c. If there is a high density of plankton in the water then there will be a low coral polyp
distribution.
d. The relationship between coral polyp distribution and plankton density is limited because they have different food sources.
Answer:
Coral polyps and zooxanthellae algae live in a symbiotic relationship to create coral reefs. The polyps give shelter to the algae while the algae create food for the polyp by photosynthesis. Therefore, the higher the density of phytoplankton, the higher the density of coral polyps.

Answer:
The answer should be A. lithosphere.
Explanation:
Firstly, let's look at the options:
C. and D, both parts of the Earth at the core, have almost nothing to do with the Earth's crust or tectonic plates except maybe having a passive effect on them.
B. mantle is where the lava that moves the tectonic plates circulates due to convection, which is the reason they move at all. But, it is not where the tectonic plates themselves are.
Therefore, finally, we have A as the answer.
(As a sidenote, the "lithosphere" means the Earth's crust.)

What does yeast produce during aerobic cellular respiration?
Answer:
Carbomdioxide and water
Explanation:
Yeast is a unicellular fungus that is capable of both aerobic and anaerobic cellular respiration depending on the availability of oxygen. Yeast undergoes aerobic respiration in the presence of oxygen but undergoes fermentation (anaerobic) in the absence of oxygen.
However, like every other organism, yeast undergoes aerobic cellular respiration to yield CARBON DIOXIDE (CO2) AND WATER (H2O) as products.
All of the following are examples of the evidence that supports the endosymbiotic theory EXCEPT A. Mitochondria and chloroplasts divide in a process resembling binary fission. B. Mitochondria and chloroplasts are similar in size to bacteria. C. Mitochondria and chloroplasts have linear chromosomes. D. Mitochondria and chloroplasts have their own genomes.
Answer:
All of the following are examples of the evidence that supports the endosymbiotic theory EXCEPT for option C. Mitochondria and chloroplasts have linear chromosomes.
Explanation:
The endosymbiotic theory essentially states that some organules of the eukaryotic cells, such as mitochondria and chloroplasts, were once free-living bacteria. Probably, these organisms must have been phagocytosed, but not digested by another cell. On the contrary, these bacteria were able to adapt to their host so that the two cells established a dependent relationship with each other.
Due to its similarities to other free-living bacteria, it is speculated that chloroplasts must derive from cyanobacteria and that mitochondria must derive from rickettsias.
This theory is supported by a few characteristics of the chloroplasts and mitochondria that suggest they were once a free cell. For example,
Both organelles present their own genetic material. This DNI is bi-catenary and circular, identical to the bacterial DNA, and very different from the eukaryotic cell´s DNA. These organelles divide by binary fission (not by mitosis) and can synthesize their own ribosomes and organelles. Both organelles present a double membrane, a characteristic that reinforces the idea of being phagocyted. The internal membrane looks identical to the bacterial membrane, while the external membrane looks like the eukaryotic one. The sizes of the organelles are similar to the size of some procaryotes.

Which of the following characteristics do eukaryotic cells have that prokaryotic cells do not have?
a nucleoid
organelles
a plasma membrane

Answer:
Organelle
Explanation:
The nucleoid is only present in the prokaryotic cell so it's not the correct option
Organelles, membrane bound organelles are only found in eukaryotic cells, hence this is the correct answer
The plasma membrane surrounds both types of cells
The cell wall can be present in both types of cells

Explain the ranking of the rate of photosynthesis in the basil plants caused by each light source
Explanation:
White light appears to be the most effective light for photosynthesis, but apart from white, red light is also effective. When white light is not used, red is more effective than its counterparts, most likely because red light has a long wavelength that allows it radiate more energy and heat than other color.

The adipose tissue metabolism of patients suffering from Von Gierke disease resembles the adipose tissue metabolism of a __________ individual.
A) Healthy
B) Starved
Answer:
The correct option is B
Explanation:
Von Gierke disease is an inborn error of metabolism (hereditary disorder) in which the body cannot convert glycogen (storage form of glucose in liver and muscle) back to glucose. This disorder is caused by the deficiency of the enzymes glucose-6-phosphatase or glucose-6-phosphate translocase. This generally causes blood sugar to be low (since liver releases this excess sugar to the body in the form of glycogenolysis when the body needs it).
Since the body cannot derive energy from the glucose present in the liver and muscle, the adipose tissue which is a storage site for energy in the form of fat is usually depleted as it becomes the alternative path for energy production (for some organs) just as in a starved individual who has had his/her glycogen storage depleted.

Answer:A
Explanation:
how many kilometers will the pacific plate travel in 1 million years
Answer:
The Pacific plate travels approximately 107 km in a million year.
Explanation:
Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)
R = d/t
To calculate it in millimeters per year we need to convert it:
1 km = 1000 m
1 m = 100 cm
1km = 100,000 cm
We know by the theory that the Pacific plates might be moving approximately between 10.6 - 10.75 cm/year. So, we might say that it moves 10.7 cm/year. So,
The Pacific plate moves 10.7 cm in one year
1 year-------------------------------- 10.7 cm
1,000,000 years ----------------- X = 10700000 cm
100,000 cm -------------- 1 km
10700000 cm -----------X = 107 km.
The Pacific plate moves approximately 107 km/my.

S. cerevisiae occurs in nature on ripe fruit. S. epidermidis naturally occurs on human skin. How do experimental results relate to the natural environment of each microbe?
Answer:
S. cerevisiae needs natural environment present on ripe fruit while S. epidermidis needs natural environment present on human skin.
Explanation:
S. cerevisiae occurs in nature on ripe fruit because the environment is suitable for them that provides food in the form of sugar while S. epidermidis naturally occurs on human skin because it needs wet and humid environment which is available on human body such as armpits. Due to the presence of suitable environmental condition, both S. cerevisiae and S. epidermidis are present on fruits and human skin respectively.

Which of these is a characteristic of index fossils? (7 points) a Found in the topmost rock layer b Found in many layers of the same rock c Have already established relative age d Are limited to a particular geographic location
Answer:
it is in fact relative age
Explanation:
Have already established relative age is a characteristic of index fossils.
What do you mean by index fossils?
Index fossils are fossils used to define and identify geologic periods. Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends.
A good index fossil is one with four characteristics: it is distinctive, widespread, abundant, and limited in geologic time. Because most fossil-bearing rocks formed in the ocean, the major index fossils are marine organisms.
Index fossils are the preserved remains of specific species found in the strata of sedimentary rock. They are easily recognized by shape and lived for either a short period of time, geologically speaking, or completely vanished from the Earth in a known extinction event.
