Describe the difference between a chemical and an electrical gradient. What's an electrochemical gradient? Do you think an electrochemical gradient can have conflicting component gradients?
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 piece of evidence would strongly support the RNA-first hypothesis? finding a protocell that could carry on metabolism as well as reproduce discovering a way to make RNA more stable than DNA finding a mechanism whereby proteins could assemble DNA out of free nucleotides being able to build microspheres that contain only protein and RNA finding a living organism that uses RNA as its genetic material
Answer:
The correct answer is - finding a living organism that uses RNA as its genetic material.
Explanation:
The RNA world theory recommends that life on Earth started with a simpler form of RNA particle that could duplicate itself. The RNA world speculation recommends that life on Earth started with a basic RNA particle that could duplicate itself without assistance from different atoms.
The RNA world theory is upheld by RNA's capacity to store, transmit, and copy hereditary data, as DNA does. RNA can go about as a ribozyme, an uncommon kind of enzyme. Since it can play out the role of both DNA and enzyme, RNA is accepted to have once been equipped for supporting free living things.
According to the hypothesis is that RNA, a nearby relative of DNA, was the main hereditary atom to emerge around 4 billion years back, however in a simpler form of life that later developed into the RNA and DNA particles that we have in life today
Thus, The correct answer is - finding a living organism that uses RNA as its genetic material

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.
A discrete, locally folded unit of protein tertiary structure usually having a specific function best describes __________. A discrete, locally folded unit of protein tertiary structure usually having a specific function best describes __________. a domain a motif a complex quaternary structure
Answer:
a domain
Explanation:
The domains are the basic units of the proteins, they are polypeptide segments (about 30 -200 amino acids) that have a defined tertiary structure and play specific biological functions including, for example, enzymatic and structural activities. Protein domains are evolutionary conserved, it means that these polypeptide segments can be found in phylogenetically related species and share sequence homology. Examples of protein domains include the zinc finger and the helix-turn-helix domains which are involved in protein-DNA interactions of transcription factors.
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.

A person cannot produce several types of proteases. Name the problem this specific person probably has and explain why.
Answer:
The person have excess amount of proteases and when this happen, the person will protein breakdown in the body or lack of protein in the body which can affect most of the organs in the body.
Explanation:
Under normal conditions in the body, blood and body tissues have a specific potent enzyme called proteases. Protease help in the breakdown of protein in the body and play important roles in defending or fight against incoming infections and inflammatory processes in the body .There is need for thslese proteases to be regulated or control because overactivity can lead to protein destruction which will lead damage of different body organs. In order to control this, blood and other tissues in the body posses enzymes with protease inhibitory activity, these enzymes help to prevent its from undergoing excessive action and potentially harmful effects.

Which sustainable practice is paired correctly with its impact on the environment? Using bamboo results in an increased use of forest trees. Practicing contour plowing results in a need for more land. Setting irrigation systems to run longer results in a reduction of water use. Building more wind farms results in a reduction of fossil fuel use.
Hey there! I'm happy to help!
Using bamboo results in an increased use of forest trees. Bamboo is a grass, not a tree. I don't see how using more bamboo would increase your usage of trees. This option is incorrect.
Contour plowing is when your plow around the contour lines (which are basically like elevation lines) of a hill or slope. This actually reduces soil erosion and lasting effects of natural storms and disasters, so it does not result in a need for more land. This option is incorrect.
Setting irrigation systems to run longer results in a reduction of water use. Irrigation is a system of watering, so you need water for it. It would not reduce water use. This option is incorrect.
Building more wind farms results in a reduction of fossil fuel use. If you are getting your power from renewable resources like the wind or the sun, you will not need to use as many fossil fuels, and this would reduce their use. This option is correct.
Have a wonderful day!
The practices that aid in economic, human and ecological dynamism and health is called sustainable practices. This procedure helps in conservatively preserving the limited sources.
The correct pairing is:
Option D. Constructing more wind farms results in a decrease in fossil fuel usage.
The practices can be explained as:
Using too many bamboos will result in the degradation of lands and increased soil erosion. It will not affect the usage of other forest trees.The method of agriculture practice in which the ploughing is done near the contour lines is called contour ploughing and does not need much land also helps in reducing soil erosion and disasters.The irrigation system conserves water and is a beneficial technique of watering the agricultural lands with an efficient amount of water.Wind energy generates more energy and power which is a renewable source compared to fossil fuels and reduces the use of petrol, diesel and coal.Therefore, option D is correct.

a) debris avalanche.
b) mudflow.
c) landslide.
d) rockfall.
Answer:
The correct option is C: landslide
Explanation:
A landslide is a huge amount of land, rocks, and other materials that moves downhill. These land moves are caused by erosion and other strengths that may cause the land to move and fall from a steep hillside. Erosion might cause separation of different material layers, and when a land o rocky layer is separated from its immediately anterior one, gravity causes the fall of these layers.
In general, these land moves are very destructive. They can cover rivers, routs, buildings, among others, putting in danger any kind of life.
There are other moves very similar to landslides, such as mudflow, avalanche, or rockfall.
Rockfall refers to the fall or big rocks from a precipice or steep hillside.
Mudflow refers to a thick stream of mud and other materials.
Avalanche refers to the collapse of snow and other materials.
