What is the equation for calculating the change in water potential? In other words, this equation allows you to determine which way the water will move in response to two different concentrations.
Answer:
The correct answer is - Ψ = ΨS + ΨP.
Explanation:
The movement of the water in a solution where is two different concentrations present can be determined by measuring the water potential (Ψ).
Water potential (Ψ) can be determined by the equation that depends on these two factors osmotic potential represent by ΨS and pressure potential represent by ΨP.
Ψ = ΨS + ΨP.

5 The theory of plate tectonics was, at first, rejected by most scientists. Now most geologists accept that tectonic plates exist and that these tectonic plates can and do move. What is responsible for the change in how scientists think about plate tectonics? A New evidence was discovered that made scientists revise their ideas. B. Tectonic plates have begun to move faster and faster over time. C There are more people studying science now than in the past. D Scientists can now travel underneath the plates and observe their motion.
Tectonic plates have begun to move faster and faster, leading to a change in scientists' thinking about plate tectonics. Hence the correct option is (B).
What is Tectonic Plates?
Tectonic plates are also known as lithospheric plates. It is a massive, irregularly shaped slab of solid rock that is composed of both continental and oceanic lithosphere. The size of the plates varies greatly from a few hundred to thousands of kilometres.
The plates are the largest in the Pacific and Antarctic Oceans. Its thickness also varies greatly, ranging from less than 15 km for young oceanic lithosphere to about 200 km or more for ancient continental lithosphere.
Earth's rigid surface known as the lithosphere acts as a skin that rests and slides over a semi-molten layer of rock called the asthenosphere. It can break into many different plates because of differences in the density of rock and differences in subsurface heating between one region and the next.
Thus, Tectonic plates have begun to move faster and faster, leading to a change in scientists' thinking about plate tectonics. Hence the correct option is (B).

Good job
The chemical symbol for chlorine is Cl. There are seven valence electrons present in chlorine.
What are valence electrons?
Valence electrons are electrons in an atom's outermost shell, or energy level. For example, oxygen contains six valence electrons, two of which are in the 2s subshell and four of which are in the 2p subshell.
The chemical symbol of the element (as found on the periodic table) is written in the Lewis symbol for an atom, and the valence electrons are depicted as dots encircling it.
The number of electrons in an atom's outermost shell is referred to as its valence electrons. The final shell of the chlorine atom now has 7 electrons. As a result, a chlorine atom contains 7 valence electrons.
Therefore, Cl is the chemical symbol for chlorine. In chlorine, there are seven valence electrons.

PLEASE HELP///3. Heather had a color blindness test, and she was surprised to discover she suffered from red-green colorblindness. She told her biology teacher, who said, “Your father is color-blind too, right?” How did her teacher know this? Why did her teacher not say the same thing to the color-blind males in the class?
Answer:
In order for a woman to have the colorblind trait, they need to be X^cX^c, meaning that they have to get the trait from both their parents. Males can either have X^cY or X^CY and since Heather has it, it is definitive that her father had X^cY, which means that he is colorblind. Males in her class, on the other hand, can get it from either their mother or father.

What is the main factor that causes bedrock to weather at different rates?
1. Elevation above sea level
2. Mineral composition
3. Age of rock layers
4. Environmental factors
Answer:
2. Mineral composition
Explanation:
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
Minerals is any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Hence, mineral composition is the main factor that causes bedrock to weather at different rates.

How do enzymes reduce the amount of activation energy needed to make a chemical reaction go?
Answer:
Enzymes reduce the amount of activation energy needed by breaking substrate molecules
Explanation:
Enzymes break down substrate molecules to lower the amount of activation energy required.
What is activation energy?The least amount of energy necessary to bring atoms or molecules into a state where they may cause chemical transformation or physical transport is known as the activation energy in chemistry.
The differential of energy content between atoms or molecules in an active or transition-state configuration and the same atoms and molecules in their original configuration is known as the activation energy in transition-state theory. In mathematical formulas for values like the reaction rate constant, the activation energy is typically denoted by the symbol Ea.
Experimental rate constants or diffusion coefficients that are determined at various temperatures are used to calculate activation energies.
Therefore, Enzymes break down substrate molecules to lower the amount of activation energy required.

In the TCA cycle, some amino acids enter directly and, therefore, can continue in the cycle to generate energy and_______ . When is available, the body can use and glycerol to make some non-essential amino acids.
Answer:
Acetyl CoA; glucose
Explanation:
Acetyl-CoA is a molecule known to be part of different reactions during carbohydrate, protein, and lipid metabolism. Pyruvate (also known as pyruvic acid) is a molecule whose decarboxylation produces acetyl-CoA. Glucose cannot be synthesized when amino acids are converted to Acetyl CoA because this molecule (Acetyl CoA) cannot be converted back to pyruvate. The citric acid cycle (CAC), also known as the tricarboxylic acid (TCA) cycle, is a group of biochemical reactions that release energy by oxidation of acetyl-CoA obtained from sources such as proteins, carbohydrates and fats. During amino acid metabolism, glucogenic amino acids and TCA intermediates can be converted into glucose through gluconeogenesis.

5 Clear Mark for Review Sacculina carcini is a barnacle that attaches to the underside of the green crab. The barnacle finds a hole in the green crab's exoskeleton, then uses microscopic hairs to feed on nutrients from the green crab's blood. The barnacle also lays its eggs in the green crab reproductive system, which sterilizes the green crab. Which term describes the role of S. carcini in this relationship?
Answer:
S. carcini is a parasitic barnacle species
Explanation:
Parasitism: In this case, one of the species is beneficiated, while the other suffers a consequence, reducing its fitness. These interactions are mostly about nutrition, although there might be other benefits too. Some parasite species might coexist with their host, while some others might get them ill to the point of causing death. Parasitic attacks might be very nocive, and even though they are not lethal in a short period of time, they might slowly kill the host.
Parasitic species consume part of the host, but not the whole body. They develop an intimate relationship with their host.
The Host increases the fitness of the parasite speciesThe parasitic species decreases the fitness of the host.By taking the nutrients from the green crab's blood and sterilizing it, the barnacle causes a decrease in the fitness of the crab. The crab becomes weaker and its survival chances decrease, and they have no opportunity to reproduce. Meanwhile, the barnacle gets stronger and reproduces normally.

What might happen to the magma convection currents if there were no radiogenic heat produced in the core?
How would this affect life on Earth?
Plz help me
Answer:
If there were no radiogenic heat produced in the core, there would be no convection currents, and life on the Earth would not be possible.
Explanation:
The convection currents are the result of heating by temperature gradients. Differences in temperature and density produce these currents. Warm materials are lighter and can ascend, while cold materials are heavier and denser, so they tend to descend. These materials movements create a circular motion pattern known as convective currents. They occur in the atmosphere, in the water, and the Earth mantle. In the last case, while the hot material emerges from the bottom areas, the cold mantle sinks, creating a circular convection current. These play a significant role in fluids circulation and might be responsible for the movements of the lithospheric plates that are over the mantle. The temperature on the surface is much inferior that the mantle´s temperature, so the lithospheric pieces sink, creating a descendent current. Near the terrestrial core, the heat might reach up to 3,500ºC, and solid materials in these areas melt and fuse. When fusing, materials lose density, becoming lighter and ascending again to the surface, creating the ascending currents. The currents of ascending materials are known as thermal feathers or plumes.
Hot ascending material keeps the surface warm, making life possible. Also, radiogenic heat produced in the core is responsible for the electromagnetic field.
The electromagnetic field protects the Earth from many particles that come forward to the surface from space, specifically from the sun. The electromagnetic field also influences the atmosphere, keeping it in its place, necessary for life on Earth.
The plate´s movement produces earthquakes and volcanic activity. Both of them also necessary for many reasons, such as keeping fertile soils and producing necessary atmospheric gasses.
Through the years, the core losses heat, and eventually, it will become solid. When this happens, convective currents will stop because there will be no heat from the bottom to make them move. The electromagnetic field will disappear, and the atmosphere will be affected as well. The Earth surface will become cold. Mantle movement will stop, and there will be no earthquakes nor volcanic activities. Every living being on Earth will be affected by this fact. Life on Earth will not be possible.
