Amajor function of the endomembrane system is

a. producing and storing energy

b. transporting substances in a cell

c. manufacturing proteins

d. directing the cell’s activities

The correct answer would be B. transporting substances in a cell .

In eukaryotic cells, endomembrane system refers to the set of membranes present inside the cytoplasm which form single functional and developmental unit.

The membranes are either connected directly or indirectly and exchange material with the help of vesicle transport.

The main function of this system is to modify, pack and transport the proteins and lipids in and out of the cell.

The main organelles which form the endomembrane system are- nuclear membrane, endoplasmic reticulum, Golgi apparatus, lysosomes, and vesicles.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.

explanation:

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
