Answer 1

Answer:

I'm feeling nice today so heres the answer

Explanation:

In the portion of the cell membrane shown in the diagram, the arrow indicates the process of active transport.

Explanation:

Active transport is one of the mechanisms of transmembrane transport, which involves the use of energy. The diagram (see image) shows the hydrogen (H⁺) output from the cytoplasm to the extracellular space, through an H⁺ pump —consuming ATP— which represents an active transport process.

The hydrophobic nature of the cell membrane prevents the free passage of hydrosoluble elements or ions, as H⁺, so they require the use of active transport to pass through it.

The other options presented are not correct, because

Respiration is a process that occurs in the mitochondria.

Diffusion is a passive transport process that does not require energy.

Cellular recognition depends on membrane proteins that act as specific receptors.

Answer 2

Answer:the answer is active transport

A 20.0g sample of metal with a specific heat of 5 J/(g°C) raised it's initial temperature to 40.0 when 500J heat was added. What was the initial temperature of the metal?

Answers

The initial temperature of the metal = 35 °C

Further explanation

Heat can be formulated :

Q = m . c . ΔT

Q = heat, J

c = specific heat, J/g C

ΔT = temperature, °C

m = 20 g

c = 5 J/(g°C)

Q = 500 J

T₁ = 40 C

the initial temperature :

[tex]\tt \Delta t(T_2-T_1)=\dfrac{Q}{m.c}\\\\40-T_1=\dfrac{500}{20.5}\\\\40-T_1=5\\\\T_1=35^oC[/tex]

The compound classification.

The compounds are classified as per several different criteria and one common elements is the specific element that is present this makes it an iconic or a molecular. The presence of the oxides, hydrides, and various atomic groups.

Hence the answer is melting point to conductivity classified as c, iconic, c, iconic, and alloy.

A poor conductor of electricity will have a conductivity classification of c. The 396 good conductors will be iconic and a 0 C not teste will have a conductivity of c. The 200 C of good conductor will be iconic and 20 C of good conductor will be alloy or iconic.

What is a Reflective surface?

A reflective surface is one which can cause incident light to bounce back (reflection).

According to this question, when light waves hit ice, most of them bounce off and radiate back into space. This means that most of the incident light reflects off the ice surface.

Therefore, the ice surface is best described as a reflective surface.

Answer:

In Niels Bohr's theory of the atom, electrons absorb and emit radiation of fixed wavelengths when jumping between fixed orbits around a nucleus. The theory provided a good description of the spectrum created by the hydrogen atom, but needed to be developed to suit more complicated atoms and molecules.

Explanation:

The ionization energies for removing successive electrons from sodium are 496 kJ/mol, 4562 kJ/mol,
6912 kJ/mol, and 9544 kJ/mol. The great jump in ionization energy after the first electron is removed
indicates that
Select one:
O a. sodium has four or five electrons.
O b. the atomic radius has increased.
c. a d-electron has been removed.
d. the noble gas configuration has been reached.

Answers

Answer:

D

Explanation:

The high jump of ionization energy indicates that we are trying to remove electron from noble gas configuration state.

The ionization energy data specifies that the Elements are from group 1 at period 3 or greater.

Removing the first electron require 496 kJ and the second ionization energy jump significantly due to the removal of electron from the noble gas configuration which is logical because electron try to maintain the especially stable state.

If an element is on the 4th row of the periodic table...how many energy levels/rings would you need to draw a Bohr 's model of the element's atom?

Answers

Answer:

4 energy levels/rings

Explanation:

By the atomic model proposed by Niels Bohr, the electrons orbit around the nucleus in shells having different energy level each with the ability to contain a given maximum amount of electrons.

The closest shell to the nucleus named the K shell, can have a maximum of two electrons, the next shell known as the L shell can have 8 electrons while the next shell, M, can have a maximum of 18 electrons

The arrangement of the periodic table is based on the number and location of electrons such that elements in the 4th row (period 4 elements) have three completed energy levels/rings before, their valence ring making the total number of rings = 4 energy levels/rings.
