The cell membrane is semi permeable in nature, that is, it allows the passage of some substances while it disallows some substances. Small and non polar molecules pass quite easily through the cell membrane but large and polar molecules can not do this.
The substances which can easily pass through the cell membranes make use of passive transports such as diffusion and facilitated diffusion to enter the cells while substances which can not pass through the cell membranes on their own make use of active transport. Examples of active transport are endocytosis and ectocytosis,
D.)The enzyme changes shape and no longer fits the substrate.
High temp causes enzymes to speed up the reaction but too much heat and the enzyme might denature, losing its shape.

The correct answer is A.
Animal cells do not have a cell wall.
A cell wall is the rigid, outermost covering of plant cells and is made up of cellulose. It is absent in animal cells. The cell wall is visible under a light microscope.
Animal cells are instead covered by a cell membrane. It is made up of lipids, proteins, and small amounts carbohydrates. It is a thin and delicate structure that can only be seen using an electron microscope.
Answer: In diagram B, the magma here is observed to be within the crust and could not come out to the surface. This signifies that the hot, rising magma, suddenly cooled down forming a huge block of mass which is considered to be an intrusive igneous body. It can be a batholith, lacolith or a pluton. This type of body is formed due to the cooling and the consolidation of hot magma.
