The cell parts common to all cells are:

Cell ,membrane, Cytoplasm ,Ribosomes, DNA .

Plasma Membrane: Every cell is enclosed by a plasma membrane, a lipid bilayer that separates the cell's interior from the external environment.

It regulates the passage of substances in and out of the cell.

Cytoplasm: The cytoplasm is the semi-fluid substance inside the cell where various organelles are suspended.

It contains water, ions, and molecules necessary for cellular processes.

DNA: Genetic material, in the form of DNA (deoxyribonucleic acid), carries the cell's hereditary information and instructions for cellular functions. It's present in all cells.

Ribosomes: Ribosomes are responsible for protein synthesis. They can be found in both prokaryotic and eukaryotic cells.

They read the genetic code and assemble proteins.

While these components are universal, eukaryotic cells have additional structures such as a nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and more, which are not present in prokaryotic cells like bacteria and archaea.

These differences highlight the distinction between prokaryotic and eukaryotic cells, but the common components mentioned above form the foundation for all cellular life on Earth.

Answer:

The organism Cyanobacteria was the first organism to inhabit t he Earth prior to the rise oxygen in the atmosphere.

Explanation:

The single-celled Cyanobacteria were known to be the first oxygen-producing organisms even before the rise of oxygen in the atmosphere or the "Great Oxidation Event," way back 3.5 million years ago. They were able to survive the harsh conditions of the Earth by photosynthesis. During this process, the Cyanobacteria would use sunlight, water and organic carbon dioxide  to produce sugar for their energy. As a waste product, oxygen was released to the atmosphere. Accumulation of the oxygen in the atmosphere was increased by the presence of the volcanic gases like hydrogen, reacting with the oxygen. This caused a reduction reaction and made a more viable oxygen-rich atmosphere.

Hawaiian eruptions are characterized by relatively fluid basaltic lava that flows relatively gently from the volcano's vent. The lava often travels in streams or rivers and can create impressive lava fountains, but the explosions and ash clouds associated with Hawaiian eruptions are generally less intense compared to other types of eruptions like Plinian, Pelean, or Strombolian eruptions.

Answer:

Plant cells have cell walls and this is how they differ from animal cells because animal cells do not have cell walls. Animals don't need cell walls because they have skeletons that help stabilize their bodies. The cell wall provides structure and strength to the cell. I saw evidence once when I was in a biology class.

I did see evidence of the cell structure in plants. Plant cells have a cell wall, which is a rigid structure that surrounds the cell membrane.

The cell wall is made up of cellulose, a complex carbohydrate that gives plants their strength and rigidity. Animal cells do not have cell walls. The cell wall provides support and protection for the cell.

Plant cells have chloroplasts, which are organelles that contain chlorophyll. Chlorophyll is a green pigment that helps plants to photosynthesize. Animal cells do not have chloroplasts. Plant cells have a large central vacuole, which stores water and other nutrients. Animal cells do not have a central vacuole.

The scientific investigation without dependent and independent variables is observing and counting bird populations, which is an observational study and not a controlled experiment.

The scientific investigation that does not include dependent and independent variables is observing and counting bird populations, which is an example of an observational study. In this type of investigation, researchers are simply making observations without manipulating any factor. Therefore, there isn't an independent variable being altered to see its effect on a dependent variable. However, in the other three options provided, there is a clear manipulation of one variable (the independent variable) to see its effect on another variable (the dependent variable), which classifies them as controlled experiments.

For example, in studying the effect of temperature on bacterial reproduction rates, temperature is the independent variable, and the bacterial reproduction rate is the dependent variable. Likewise, when investigating the effect of mass on the speed at which an object falls, mass is the independent variable, and the falling speed is the dependent variable. In testing a model car's air flow resistance at different wind speeds in a wind tunnel, wind speed is the independent variable, and air flow resistance is the dependent variable.

Answer:

Label A: Nucleus

Label B: electron cloud

Explanation:

Without the precise diagram, Label A might refer to the central atom or the atomic number, and Label B could refer to surrounding atoms or the mass number. These labels generally correspond to specific parts of an atom or molecule, which include the nucleus and electrons in the context of atomic structure.

The question appears to be related to the structure of the atom and its components. Although the exact diagram for Label A and Label B is not provided, based on the provided references, we can infer that Label A may refer to the central atom in a molecule, while Label B could be addressing the atoms surrounding the central atom. Moreover, in the context of atomic structure, Label A might signify the atomic number, and Label B might represent the mass number, as indicated in reference to Figure 1.8.3 which states that the atom's symbol includes the atomic number and mass number.

In atomic physics, key parts of the atom typically include the nucleus (comprised of protons and neutrons) and the electrons that orbit around it. The nucleus is the dense center of the atom, containing most of the atom's mass, while the electrons are subatomic particles with a negative charge that move around the nucleus in what are known as electron clouds or shells.

If the diagram provided to the student was similar to the one described in the references, Label A and Label B would likely be pointing to specific parts of the atom or to elements in a compound or molecule depending on the context given within the diagram.

Answer:

What does that even mean

In a hypertonic environment, a cell will shrink due to water loss. In a hypotonic environment, a cell will swell due to water gain. In an isotonic environment, the cell will maintain its size as there is no net water movement.

Whether a cell will shrink or swell depends on the type of environment it is in. When it is placed in a hypertonic environment, which has a higher concentration of solutes, the water will leave the cell to maintain equilibrium, and the cell will shrink. This process is known as crenation.

However, if the cell is in a hypotonic environment where the concentration of solutes is low, water will move into the cell to balance out the solute concentration, causing the cell to swell. If the intake of water goes to excess, the cell may burst, a process known as lysis, due to the excessive influx of water.

Finally, in an isotonic environment, where the concentrations of solutes inside and outside the cell are the same, there is no net water movement, so the cell will neither swell nor shrink.
