Some plant cells need energy to carry nutrients across the cell membrane. Which type of energy transformation does these plant cells use to bring the nutrient molecule inside the cell membrane?

thermal energy to kinetic energy

potential energy to light energy

chemical energy to kinetic energy

kinetic energy to potential energy

Answers

Answer 1

Answer:

Answer

The answer is option 4

Answer 2

The energy transformation during nutrients transportation across the cell membrane is transformation from chemical energy to kinetic energy, where the uphill and downhill movements of molecules based on concentration gradient carries the whole process.

What is energy transformation?

The total energy in a system is always conserved. However, one form of energy can be transformed into another form. For example we uses electrical devices such as bulbs fan etc, wherever the energy transformation is getting way from electrical energy to light or mechanical energy.

In plant cells nutrient molecules and ions are balanced inside and outside the cell and hence they are transported across the cell membrane by a concentration gradient with a chemical energy produced by the molecules.

The chemical energy inside of the ions and molecules converts to kinetic energy to transport itself through downhill and uphill mechanisms with aid of various enzymes and electron channels.

How is the term stable used in the text?

Answers

Answer:

When something is stable, it's fixed and steady. If you needed advice, you'd probably go to your most stable friend, the one least likely to act crazy or be easily upset.

Explanation:

Whether you're talking about an object or a person, the adjective stable implies reliability and strength. You can describe a government as stable, or a relationship, or a desk. A completely different meaning of stable is the noun "building used for housing horses or other animals." Both senses of the word come from the Latin stabilis, "firm or steadfast."

Question 1 of 10 What is molarity a measurement of? O A. The volume of liquid containing a dissolved substance B. The grams of a substance dissolved in a liquid O c. The concentration of a substance dissolved in a liquid O D. The number of moles of a dissolved substance

Answers

To do this measure called molarity is commonly used. Molarity (M) is defined as the number of moles of solute (n) divided by the volume (V) of the solution in liters. It is important to note that the molarity is defined as moles of solute per liter of solution, not moles of solute per liter of solvent.                    

so the answer is D.

hope this helps have a great day....!

According to the concept of molar concentration, molarity is  defined as the number of moles of a dissolved substance.

What is molar concentration?

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.

Two atoms gain electrons and an electrostatic force attracts them.

Answers

One atom gains an electron while the other atom loses an electron and a electrostatic force attracts them.

The situation which best describes the ionic bond is “ One atom gains an electron while the other atom loses an electron, and an electrostatic force attracts them”.

What is an ionic bond?

An ionic bond is formed between two atoms by donating an electron from the electropositive atom and withdrawal of that electron by the second atom which is electronegative and thereby attaining stability by making their valency completed.

The electron loss-gain interaction make an electrostatic force of attraction between them, where the electrons from the electropositive atom is attracted towards the electronegative atom.

Thus the two atoms are bound together by the electrostatic force of attraction created by the electron donation. Hence, option b is correct.

Which element has an outer(ending) electron configuration of s2p4?

Answers

The question is in complete, the complete question is:

Which element has an outer electron configuration of s 2 p4 ?

(A) Ca (B) Cr (C) Ge (D) Se

Answer:

(D) Se

Explanation:

The outer electronic configuration of an atom reflects the group to which it belongs in the periodic table. Each group has its unique outermost electron configuration and number of electrons found in the outermost shell of the atoms of elements in the group.

s 2 p4  is the unique outermost electron configuration of group 16 elements. Group 16 elements have six electrons in their outermost shell. If we consider the options, only Se is a member of group 16. Hence it is only Se that has the outermost electron configuration s 2 p4 .

An element which has an outer (ending) electron configuration of [tex]s^2p^4[/tex] is: Oxygen.

Electron configuration can be defined as a formula that is used to denote the distribution of the atoms of a chemical element in an atomic orbital.

Basically, electron configuration uses four (4) main letters to illustrate the distribution of atoms in an atomic orbital:

spdf

The electron configuration of [tex]s^2p^4[/tex] indicates that the chemical element is in Group 6 and has six (6) electrons in its outermost shell.

Hence, a chemical element such as Oxygen (O) or Selenium (Sn) in Group 6 of the periodic table would have an electron configuration of [tex]s^2p^4[/tex].

A) Pb < P < Ba
B) Ba < P < Pb
C) Pb < Ba < P
D) Ba < Pb < P

Answers

Answer:

D) Ba < Pb < P

Explanation:

Barium (Ba): 5,2117

Lead (Pb): 7,4167

Phosphorus (P): 10,4867

Increasing order of ionization energy:

Ba < Pb < P

Electronic configurations of given elements

Pb: [Xe] 6s² 4f¹⁴ 5d¹⁰ 6p²

P:   [Ne] 3s² 3p³

Ba: [Xe] 6s²

All the given elements have stable half-filled subshells. But phosphorus has the smallest atomic size among them, so it will have the lowest tendency to remove an electron from its valence shell and hence will require the highest amount of ionization energy.  Barium has a higher atomic size than lead, therefore it has lower ionization energy than lead.

How are ionization energy and atomic size related?The force of attraction is stronger when the electron is closer to the nucleus, and as a result, more energy is needed to overcome this attraction and remove the electron.Therefore, the ionization energy increases with decreasing radius and vice versa.
