What particles cannot pass through the cell membrane
Large molecules such as proteins and nucleic acids, charged particles (ions), and polar molecules such as glucose are examples of particles that cannot pass through cell membranes.
The lipid bilayer of the cell membrane makes it difficult for charged and polar substances to pass through. However, small, non-polar molecules and compounds that are lipid soluble can readily diffuse across the cell membrane. Aquaporins make it easier for water molecules to do this by facilitating osmosis.
The selective permeability of the cell membrane enables it to control the passage of molecules, preserving cellular harmony and functionality. In contrast, diffusion allows the easy passage of small, non-polar molecules such as oxygen, carbon dioxide, and lipid-soluble compounds through the cell membrane.

1. 1 Water makes up between 70-90% of the weight of most life forms, and nearly all chemicals present in living matter are soluble in it. Water is such a good solvent because the molecular structure of a water molecule is polar, having a negative charge at one end and a positive charge at the other end. Which model best represents a water molecule? A. B. C. D.
Answer:
The correct model is D.
Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.
Explanation:
A water molecule is composed of one atom of oxygen and two atoms of hydrogen.
A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.
The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.
A scientist is studying a cell and can clearly see that it has ribosomes and mitochondria. Which statement best
describes how the cell could be classified
the cell is prokaryotic because it contains ribosomes
the cell is prokaryotic because it contains mitochondria
the cell is eukaryotic because it contains ribosomes
the cell is eukaryotic because is contains mitochondria
Answer:
i belive its d
Explanation:
The cell is eukaryotic because it contains mitochondria is the best line to define eukaryotic cells. Therefore, option "D" is correct.
What is eukaryotic cells?Eukaryotic cells are large, intricate organisms with a nucleus enclosed within the nuclear membrane. Eukaryotic cells can be found in animals, plants, protozoa, and fungi.
In prokaryotic cells, the cytoplasm is available, however, it is deficient in most cell organelles. It comprises both organelles and cytoplasm in eukaryotic cells, and both are present. There are mitochondria, which are the cells' powerhouse. There are two kinds of organelles present which is membrane-bound and non-membrane-bound.
Therefore, eukaryotic cells are also referred to as true cells having membraned nuclei.

B. A virus has cell, a nucleus and does not eat.
C. A virus does not eat, use energy or have cells.
D. A virus does not have cell, produces carbon dioxide and uses oxygen.
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.

Which of these could be an example of a freshwater wetland?
O A. Pond
O B. Lake
O C. Swamp
O D. Forest
Answer:
b lake your welcome
Explanation:
because lakes have trees that create the fresh water for the fishes to swim in i think?
An example of a freshwater wetland body is a lake. Thus, the correct option is B.
What is a lake?A freshwater wetland is a waterbody which is supplied with water from all the nearby streams and rivers. Freshwater wetlands are the ecosystems which are affected by the permanent or temporary inundation.
A lake is a naturally occurring, relatively very large body of water which is localized in a basin that is surrounded by land, with much slower-moving flow than that of any inflow or outflow streams that serve to feed or drain the lake. Lakes lie completely on the lands and are separate from that of the ocean, however like the much larger oceans, they also form a part of the Earth's water cycle by serving as many large standing water reservoirs as possible. Most of the lakes are freshwater, however some are salt lakes with salinities even higher than that of the seawater.
Therefore, the correct option is B.

Answer:
The surfaces of the leaves of many plants help to reduce water loss because they are not water-permeable. How does the biomolecule that makes up this surface differ from other biomolecules? It is made up of polymers of amino acids. It is made up of long chains of fatty acids.
Explanation:
The biomolecules that make up this surface of leaves differ from other biomolecules by the fact that they are made up of long chains of fatty acids. Thus, the correct option is A.
What are Biomolecules?Biomolecules may be defined as those types of molecules that are significantly present in the body of living organisms and are required to perform essential functions like cell division, morphogenesis, or development.
The long chains of fatty acids typically consist of a hydrophobic arrangement that prevents the movement of water from one part to the other. This specific property of forming a water barrier is only present in fatty acids.
Due to this, the surfaces of the leaves of many plants help to reduce water loss because they are not water-permeable, which means to prevent the migration of water.
Therefore, the correct option for this question is A.
