Different types of cells can have certain organelles and structures in common. Which types of cells definitely contain cell walls?
SC.912 L 14.3
O plant and animal cells
0 plant and eukaryotic cells
o plant and prokaryotic cells
animal and eukaryotic cells
Answer:
plant and eukaryotic cells (B)
Explanation:
animal cells have a cell membrane but no cell wall and prokaryotic organisms lack a nucleus or any other membrane bound cell organelle.
Plant and prokaryotic cells definitely have a cell wall. So, the correct option is C.
What is Cell wall?Cell wall is defined as the structural layer that consists of polysaccharides and is present outside the plasma membrane which can be rigid, rigid and flexible. This provides protection to the cell from external factors that may be harmful to the cell and also provides structural support.
Plant and prokaryotic cells definitely have a cell wall. The cell wall of a prokaryotic cell is present under the capsule while the cell wall of a plant cell is a specialized form of extracellular matrix that surrounds each cell of a plant. This provides structural support to the cell and protects the cell against infection and mechanical stress
Therefore, the correct option is C.

What is Clean water act?The Clean Water Act (CWA) establishes the fundamental framework for controlling the discharge of contaminants into American waters and for controlling surface water quality requirements.
The Federal Water Pollution Control Act, which served as the CWA's starting point, was passed in 1948; nevertheless, in 1972, it underwent a considerable organizational and growth. As the Act underwent modifications in 1972, "Clean Water Act" gained its widespread name.
The EPA has launched pollution control initiatives under the CWA, such as regulating industrial effluent. Moreover, the EPA has created national water quality guidelines and recommendations for contaminants in surface waterways.
Therefore, The map shows the number of waterways in each state that still fail to meet EPA standards Pennsylvania (PA).

Critics claim that genetic researchers overestimate which of the following?
Please select the best answer from the choices provided
environmental influences on personality
genetic influences on personality
cognitive influences on personality
evolutionary influences on personality
Answer:
genetic influences on personality
Explanation:
Personality traits are influenced by both inheritance (genes) and environmental (e.g., educational, cultural background) factors, as well as by the interaction between genetic and environment. In genetics, it has been believed that personality traits have a strong genetic component, which has been observed in large-scale twin studies. Some personality traits that have been shown to have a strong genetic component include neuroticism, agreeableness, extraversion and openness. These traits are influenced by the combined effects of numerous genes (i.e., they are complex quantitative traits), thereby a significant number of researchers in other fields argue that the genetic components of personality traits are often overestimated.

the water in the solution moves into the plant cell.
the water in the solution moves out of the plant.
the solutes in the solution have a higher concentration than the solute concentration inside the plant cell.
the solutes in the solution have a lower concentration than the solute concentration inside the plant cell.
the water is moving down its concentration gradient from high to low. the water is moving down its concentration gradient from low to high.
Answer:
The correct answer is -
the water in the solution moves into the plant cell
the solutes in the solution have a lower concentration than the solute concentration inside the plant cell
the water is moving down its concentration gradient from high to low.
Explanation:
The hypotonic solution consists low concentration of solutes and a higher concentration of water as compared to the concentration of solutes and water of other solutions or cells. Water tends to move from a higher concentration of water to a lower concentration of water therefore the cell swell and then ultimately burst.
Water movement in such conditions is known as the movement down the concentration gradient as it moves from its higher concentration to a region of its lower concentration.
