Answer:

D) Bees and plants or sea anemonies and clownfish.

i think..

Explanation:

A pearlfish spends the day inside the alimentary tract, or intestines, of a sea cucumber. The fish emerges from the sea cucumber at night to feed on small crustaceans. The pearlfish gets a safe place to live. The sea cucumber does not gain anything from the relationship, nor is it harmed. This is similar to the relationship between bees and plants or sea anemonies and clownship and the correct option is option D.

Symbiosis is a close relationship between two species in which at least one species benefits.

For the other species, the relationship may be positive, negative, or neutral.

There are three basic types of symbiosis: mutualism, commensalism, and parasitism.

Mutualism is a symbiotic relationship in which both species benefit. Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected.

One species typically uses the other for a purpose other than food. Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed.

Therefore, a pearlfish spends the day inside the alimentary tract, or intestines, of a sea cucumber. The fish emerges from the sea cucumber at night to feed on small crustaceans. The pearlfish gets a safe place to live. The sea cucumber does not gain anything from the relationship, nor is it harmed. This is similar to the relationship between bees and plants or sea anemonies and clownship and the correct option is option D.

Answer:

The attractive force between them decreases

Explanation:

This is because they become localised.

Answer:

Smashing the cube into pieces

Explanation:

The reason for this is that if we were to smash the cube we would have a larger surface area which means more manganese oxide would be dissolving per second which means we would have a faster reaction rate where if we were to chill the peroxide it would dissolve slower which in turn slows the reaction. For example a spoonful of granulated sugar will react with water faster than a sugar cube.

The rate of the reaction is increased by smashing the cube into pieces. C is the correct answer.

The reaction rate, also known as the rate of reaction, is the rate at which a chemical reaction occurs.

It is typically classified as proportional to the change in product concentration per unit time and the change in reactant concentration per unit time. Different chemical reactions have different reaction rates.

The amount of reactants, the temperature, and the catalyst all influence the reaction rate.

When a cube of manganese oxide was added to a solution of hydrogen peroxide, water and oxygen were produced, just as in the given reaction. The reaction did not deplete manganese oxide.

The reaction will be altered by smashing the cube into pieces as the it can boost appropriate conditions for the reaction.

Thus, C is the correct answer.

Answer:asexual- Energy is not required to find a mate. Offspring are genetic clones. A negative mutation can make asexually produced organisms susceptible to disease and can destroy large numbers of offspring. Some methods of asexual reproduction produce offspring that are close together and compete for food and space.

Explanation:During sexual reproduction the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents.

Answer: In a vacuum, the objects fall at the same rate independent of their respective masses. That means coin and feather both reach ground at same time in a vacuum. Larger objects experience more air resistance than smaller objects. Also, the faster an object falls, the more air resistance it encounters.

Answer:

m = 190. g MgCl2

Explanation:

Use a molar ratio to get the # of moles MgCl2 produced from 4.00 mol of HCl:

4.00 mol HCl × (1 mol MgCl2/2 mol HCl) = 2.00 mil MgCl2

So 2.00 moles of MgCl2 will be produced. To find the mass in grams, use the molar mass of MgCl2:

2.00 mol MgCl2 × (95.211 g MgCl2/1 mol MgCl2)

= 190. g MgCl2

Answer:

Option 2: X is the screening constant, & it remains constant across a period.

Explanation:

I took the test and got the question correct :)

As we move across the period, X is the screening constant, and it remains constant across a period.

As we move across the period, the size of atoms become smaller because of an increase in the size of the nuclear charge. This leads to a decrease in atomic radius.

As the size of atom decreases, the screening effect on the outermost electron decreases accordingly. Hence, as we move across the period, X is the screening constant, and it remains constant across a period. This is because, no new shells are added across the period.

Answer:

See Explanation

Explanation:

The equation of the reaction;

KHSO4(aq) + KOH(aq) -------> K2SO4(aq) + H2O(l)

Number of moles of KHSO4 = 49.6 g/136.169 g/mol = 0.36 moles

Since the reaction is in a mole ratio of 1:1, 0.36 moles of K2SO4 is produced.

Number of moles of KOH = 25.3 g/56.1056 g/mol = 0.45 moles

Since the reaction is 1:1, 0.45 moles of K2SO4 is produced

Hence K2SO4 is the limiting reactant.

Mass of K2SO4 formed = 0.36 moles of K2SO4 * 174.26 g/mol = 62.7 g

So;

1 mole of KHSO4 reacts with 1 mole of KOH

0.36 moles of KHSO4 reacts with 0.36 * 1/1 = 0.36 moles of KOH

Amount of excess KOH = 0.45 moles - 0.36 moles = 0.09 moles

Mass of excess KOH = 0.09 moles * 56.1056 g/mol  = 5 g of excess KOH

Answer:

[CH₃COOH] = 1.70 M

Explanation:

When we talk about concentration we can determine Molarity

Molarity determines the moles of solute that are contained in 1L of solution.

In this case our solute is the acetic acid.

M = mol/L

M = 0.99 mol /0.58L → 1.70 M

We can also make a rule of three

In 0.58 L of solution we have 0.99 moles of solute

In 1 L of solution we may have (1 . 0.99) / 0.58 = 1.70 moles

Acetic acid is a weak acid, partially dissociated in water.

CH₃COOH  +  H₂O  ⇄  CH₃COO⁻  +  H₃O⁺     Ka
