Answer:
Selectively permeable or semipermeable means specific substances are allowed to pass through the plasma membrane.
Explanation:
The plasma membrane is selectively or semipermeable in nature because the plasma membrane allow only specific molecules such as nonpolar substances or hydrophobic substances such as steroidshormone to pass through it and prevent the passage of polar solute molecules such as water,glucose.
To transport these polar solutes across the membrane an additional protein is needed in case of transport of water channel protein is needed whereas in case of glucose transport carrier protein is required.
Answer:
Phalanges: long bones
Sternum: flat bone
Vertebrae: Irregular bone
The diagram is not clear but I will only try to answer what I can see
A is the pilus and it help the bacteria to attach itself to a specific surfaces or to other cells
B is the cytoplasm and it protect the cell from damages and also store molecules required for cellular processes
C is the plasma membrane they keep toxic substance out of the cell and regulate the in and out of specific molecule
K is the chloroplast and it store chlorophyll which is responsible for the color pigment
M is the large vacoule, and it stores waste , water and nutrients in the cell
I can’t see L well , that is why am unable to answer it
Thank you
The answer is stratosphere
The mitotic spindle pulls the chromosomes together at the metaphase plate. Microtubules from opposite spindle poles grab the two sister chromatids of each chromosome. In metaphase, the spindle has collected all the chromosomes and lined them up at the middle of the cell, ready to divide.
<h3>
What are chromosomes?</h3>
Chromosomes are the greatest level of DNA and protein organization. Chromosomes' primary job is to transport DNA and genetic information from parents to offspring. During cell division, chromosomes play a vital role. They keep DNA from becoming twisted or damaged.
The metaphase plate is a plane or region that is about equidistant from a dividing cell's two poles.
