There are three factors that a substance must have in order to diffuse through a cell membrane.

1. A substance should have the right concentration in order to diffuse through membrane as we know that molecules can only diffuse through areas of high concentration to a lower concentration. Hence the substance should have higher concentration that the cell to diffuse through the membrane.

2. The substance should not be charged as the cell membranes do not allow charged particles to enter into the cell unless the cell has electrical potential.

3. The size of the particles matters as molecules of smaller size can easily diffuse through the cell membrane

$\huge\red{ \mid{ \underline{ \overline{ \tt Fe }} \mid}}$

→ Molar Mas = 55.85 g/mol

$\huge\orange{ \mid{ \underline{ \overline{ \tt NaCl }} \mid}}$

→ Molar Mass = 58.44 g/mol

$\huge\red{ \mid{ \underline{ \overline{ \tt CH₄ }} \mid}}$

→ Molar Mass = 16.02 g/mol

$\huge\orange{ \mid{ \underline{ \overline{ \tt Ca(OH)₂ }} \mid}}$

→ Molar Mass = 74.10 g/mol

During primary succession, an ecosystem cannot 're-build' with large trees and bushes. Explain.

Luden [163]

I believe they cannot start with big trees and bushes because the there is not enough nutrients in the soil, so instead pioneer species pave the way for primary succession.

sergejj [24]

The most likely complication of this disease is the development of Empyema.

Explanation:

The patient has symptoms of fever, dyspenea (breathlessness with chest pain), cough and sputum which directs towards empyema as they are symptoms of pneumonia and prolonged symptoms would cause empyema.

The infiltrates in the posterior segments of upper lobe of the right lung results in bulging fissure causing necrosis lesion which would cause the complications of empyema.

The empyema is the condition in which pus cells are formed in thoracic cavity, in pleural fluid bacterial infection occurs due to pneumonia or surgery of chest.

The empyema risk is high for diabetics, pulmunary infected and alcoholism.

Why do you think bread turns moldy less quickly when it is kept in a refrigerator than when it is kept at room temperature

PSYCHO15rus [73]

Hi there!

I think bread turns moldy less quickly when it is kept in a refrigerator than when it is kept at room temperature because bacteria eats foods like bread and causes mold, and less bacteria grow in colder temperatures. Since less types of bacteria thrive in colder temperatures, it takes longer for less bacteria to create mold.

Hope this helps!
