Answer:
1) The difference between chemical gradient and electrical gradient is that chemical gradient refers to the change in concentration of an ion or molecule in a solution across a biological membrane while electrical gradient refers to the existence of an electrical potential difference that leads to the movement of charged ions towards or away from the electrical potential
2) Electrochemical gradient is the charge and ion concentration difference across a biological membrane
3) No because electrochemical gradient which consists of both an electrical and chemical gradient have a complementary effect in determining the level of the electrochemical gradient.
Explanation:
The electrochemical gradient is the gradient of the electrochemical potential and is usual for a positive and negative ion that can move across the membrane.
What is the electric gradient ?The gradient is made of two parts that are chemical which is different in solutes that can move across the membrane and have an electrical component that shows difference in changes across the membrane.
The electrostatic gradient is a potential used in an iron that can be used across the membrane. Due to unequal concertation of ions, they will move across the simple diffusion.
The electrochemical has potential in electroanalytical industries as batteries and fuels. The gradient has contrasting components as change across the membrane.

Which best describes what happens if two waves meet and build on each other?
A. constructive interference
B. destructive interference
C. reflection
D. absorption
Answer:
constructive interference
Explanation:
when two waves build off of each other, they interfere with one another and construct. therefore, the answer is constructive interference.
When the path difference between subsequent crystal planes is equal to an integral number of electromagnetic radiation wavelengths, constructive interference occurs. Thus, option A is correct.
What is the constructive interference?Where the lines (which represent the peaks) cross over one another, constructive interference occurs. In other words, constructive interference occurs when two waves are in phase.
When two waves are entirely out of phase (a peak is located in the middle of two waves), destructive interference ensues.
Constructive interference is the phenomenon where the total amplitude of two waves is equal to the sum of the amplitudes of the separate waves when two waves are in phase and their maxima add.
Therefore, constructive interference best describes what happens if two waves meet and build on each other.

Q2. A student places peaches into a pure water solution
Give two differences you would expect to find in the water
after ino hours.
Answer:
The correct answer - peaches will swell.
Explanation:
In the hypotonic solution, solution has a higher water potential than that of the cell of peach, so water will move from a region of higher water potential to a lower water potential across via osmosis.
Peaches have more solutes than pure water as it has higher sugar content than pure water. Hence, endosmosis will take place which means the water molecules will move from outside to inside of the peaches through wall of peaches takes place. Due to this, peaches will swell eventually.
Thus, the correct answer - peaches will swell.

Both the full body plate type and the half body plate trait are also present in an ocean near the lake. Where would you expect a higher occurrence of the full body plate trait, in the lake or the ocean? Explain your answer.
Answer:
In the ocean
Explanation:
Ecological divergence leads to selection of essential traits against migrants and hybrid species. The full body plate type traits requires attention for occurrence in an environment which is free from issues such as resource limitation or predator attacks. In vast ocean spaces , resources are not a limiting factor in ocean and also there is no risk of predators as there is huge chunk of space, thus, full body plate type will occur in higher number in the ocean.
hope it helps you..
The place where there would be a higher occurrence of the full body plate trait would be:
In the ocean
Based on the given question, we can see that when the ecological divergence which helps the full body plate type to have a higher occurrence in the lake because there is a need for attention.
With this in mind, we can see that in the ocean, there is the higher chance for the full body plate because of the absence of predators and the abundance of resources in the ocean.

Suppose that an unusually high degree of aurora kinase activity is observed in the cervix. What could we reasonably conclude about C5M treatment efficacy across all cervical cancer cell lines, using this new information and the data within the passage
Answer:
The division of cervical cancer cells will be inhibited
Explanation:
Aurora kinases are a type of serine/threonine kinase enzymes that play critical functions during cell proliferation, and they are recognized to be potential targets in cancer therapy. The benzo[e]pyridoindole (C5M) agent is a hydrosoluble inhibitor of aurora kinases capable of inhibiting cell proliferation. C5M induces mitotic arrest by faulty (no separation) of the sister chromatids during cell division, thereby eventually leading to polyploidy and finally triggering cell death. It has been shown that C5M acts to prevent the entry in mitosis by inhibiting histone 3 (H3) phosphorylation of aurora kinases.
Roses come in many different colors. What is the difference between a rose that is
red and a rose that is yellow?
Answer:
different allele
Explanation:
A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal? A. In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant. B. In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle. C. Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells. D. In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a photosynthesizing organism only when it requires food.
Answer:
Option C
Explanation:
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
Elysia chlorotica which is a form of sea slug feeds on a specie of the genus Vaucheria (an algae) and then retains only the chroloplasts of these algae which it uses for its own supply of energy.
The algal partner in lichens is the photosynthesizing partner. It produces food and this is its role in the relationship. The fungi are heterotrophs and cannot photosynthesize food. The fungi contribute to the relationship my absorbing mineral and water and presents it to the algae.
Answer:
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.

smaller amplitude.
O Wave A has a higher frequency because it has a
shorter wavelength.
The waves have the same frequency because they
have the same wavelength.
O The waves have the same frequency because they
have the same amplitude.
Answer:
O. Wave A has a higher frequency because it has a shorter wavelength.
Explanation:
Wavelength refers to the distance between two crests while frequency refers to the number of waves passes through a specific point per second. Frequency and wavelength are inversely proportional to each other. Inversely proportional means if one increases, the other decreases and vice versa. If the frequency of the wave is higher so its wavelength becomes shorter and if the frequency of the wave is shorter so its wavelength is higher.
Answer: B.
Explanation: Wave A has a lower frequency because it has a longer wavelength.

Answer:
Answer:C) The patient may have internal bleeding and cuts may not stop bleeding.
Explanation:
Platelets are cells that form scabs to help stop the bleeding of wounds. When you have low platelets, you can have fewer scabs at a time, so wounds will bleed more. If you have dangerously low platelets, any wound you have will not close and you will not stop bleeding without outside help.
