Which of the following describes a state of equilibrium?

Answer:

Flatworms and cnidarians

Explanation:

In simple organisms, such as cnidarians and flatworms, every cell in the body is close to the external environment. Their cells are kept moist so that gases diffuse quickly via direct diffusion. Flatworms are small, literally flat worms, which 'breathe' through diffusion across the outer membrane

Answer:

Either A or B

Explanation:

Prokaryotic cells are unicellular.

At 100x total magnification, we would see eukaryotic cells with very little detail. So the correct option is C.

The ratio of the size of the image of an object to the actual size of an object in a plane perpendicular to the optical axis is referred to as magnification.

If the value of the linear magnification is negative, the image formed will be invested. If the value of the linear magnification is positive, the image will be erect.

The magnification of a microscope is calculated as the magnifying power of the objective lens and the eyepiece lens. This is called the total magnification of the microscope.

Now, the total magnification is 100x, and the magnification of the eyepiece lens of 10x.

Let the magnification of the objective lens be y.

10x × y = 100x

y = 100x / 10x

y = 10x

So, an objective lens at 10x is used to observe the eukaryotic cell with very little detail.

Therefore, the correct option is C.

Both are formed when the groundwater gets heated

Explanation:

This is correctamundo

"why?"- you ask

well because when groundwater gets all hot and worked up we get a result in the form of geysers and hotsprings!

Have a great day and wash your hands and STOP TOUCHING YOUR FACE!

jk haha- please don't be take this seriously good day to you all!

Answer:

B. Both are formed when the groundwater gets heated.

Explanation:

Hot springs and geysers are very similar when it comes to how they are formed. The obvious difference is that geysers force up jets of water, whilst hot springs flow water out on their own. They are both formed when the groundwater gets heated from molten rock(magma).

This is reliable because I took the same quiz and got the question right.

Answer:

The correct answer is - The point closest to the scalp.

Explanation:

In order to analyze a strand of hair investigators need to collect the DNA. To analyze a strand of hair the DNA must be nuclear DNA which can be found at the root of the hair near the scalp as the point, hair attached to the scalp there are cells that can provide the nuclear DNA. Any other section or the part of the hair strand does not contain the nuclear DNA so analyze DNA would not be possible.

Answer:

D. a reactant that is catalyzed by an enzyme

Explanation:

A substrate is a reactant that is catalyzed by an enzyme. Therefore, the correct statement is option D.

A substrate is a reactant molecule that binds to the active site of an enzyme and the enzyme then chemically transforms the substrate through a series of catalytic reactions.

Enzymes are the catalysts that are used to increase the rate of biochemical reactions by lowering down the activation energy that is required for the reaction to occur. The substrate when binds to the active site of the enzyme, it forms an enzyme-substrate complex followed by its conversion into one or more products. When the product is formed, enzyme gets released from the product.

A catalyst is a substance which is used to lower down the activation energy required by the reaction, thereby, increasing the reaction rate to form a product.

Therefore, substrate is a reactant that is catalyzed by an enzyme.

Answer:

# Diffusion is a down hill process.(flow is from higher concentration to lower concentration)

# It does not require energy.

but,

# Active transport is a uphill process.(flow is from lower concentration to higher concentration)

# It requires energy.

Two features of diffusion that do not apply to active transport are:

Diffusion is a process by which molecules move from an area of high concentration to an area of low concentration, until they reach a state of equilibrium where there is no further net movement of molecules.

This occurs because molecules are in constant random motion, and they will naturally move from areas where they are more concentrated to areas where they are less concentrated. This process does not require energy input, and it will continue until the concentration of molecules is the same throughout the system.

Active transport, on the other hand, is a process by which molecules are moved across a membrane against their concentration gradient, from an area of low concentration to an area of high concentration.

This process requires energy in the form of ATP, which is used to pump molecules or ions against their concentration gradient. Active transport is able to move molecules or ions against their concentration gradient because it uses energy to change the shape of transport proteins in the membrane, allowing them to move molecules against their concentration gradient.

Therefore, two key features of diffusion that do not apply to active transport are that diffusion is a passive process that does not require energy input, while active transport requires energy input in the form of ATP.

Answer:It helps an organism reproduce and therefore appears more often. And since dominant alleles sometimes are heterozygous, even if an organism with the dominant gene was able to reproduce, it could still produce a recessive offspring.

A) a feature of the landscape

Explanation:

got it right on edge

A landform is the set of forms that stand out on a plane or surface, being a feature of the landscape.

It is an outstanding texture of a surface that has different variations, among the most characteristic reliefs of the earth's surface are mountains, plateaus and plains.

These textures are presented in the form of irregularities and unevenness within a terrestrial or aquatic ecosystem, which provides a feature in a given landscape.

Therefore, we can conclude that a landform is formed by everything that protrudes from a flat surface or that modifies it, that is, it is the set of irregularities or features of a landscape.

Answer:

See explanation

Explanation:

I will try to explain each point mentioned to the best of my ability.

The dissolution of calcium chloride in water is endothermic hence more solute dissolves as the temperature increases. When the solution cools, the solubility of the solid also decreases with decreasing temperature hence the solid reappears.

When soda is heated, carbon dioxide gas is evolved thereby decreasing the amount of dissolved carbon dioxide.

Let me state that increase in volume of solvent increases the amount of solute that can dissolve in it. This is why 250ml volume of solvent can dissolve more solute than 100ml of solvent.

Also, temperature is an important factor when discussing the solubility of a solute. This is why the temperature at which a certain value of solubility is quoted must be indicated. For solids, solubility increases with increase in temperature.

Lastly, the solubility of sodium chloride is independent of temperature. This is clearly seen by plotting a solubility curve.

they are unaffected by changes in temperature. t
