Answer:

a network of proteins that holds homologues together.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

The synaptonemal complex is a network of proteins that holds homologues (homologous chromosomes) together.

Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.

Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;

I. SC protein-1 (SYCP1).

II. SC protein-2 (SYCP2).

III. SC protein-3 (SYCP3).

In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.

Voltage across the cell membrane is determined by the concentration of which 2 types of charged particles?
lisabon 2012 [21]

The answer is; Sodium (Na+) and Potassium (K+) Ions


These cations are pumped out of the cell by Na+-K+ transmembrane protein pumps leaving the inside of the cell electronegative in relation to the extracellular matrix. This membrane potential is significant especially for neurons. Depolarization of the membrane enables transmissions of an impulse along the neurons.

Your lab group is experimenting with the diffusion of molecules across a membrane. Dialysis tubing is used as a model cell membr
Margaret [11]

Answer: the membrane channel

Explanation:

In passive diffusion, the small water molecules can move across the phospholipid bilayer seen in blue. This layer acts as a semi-permeable or selectively permeable membrane; its hydrophilic heads are attracted to water (seen facing outwards) while its water-repellent hydrophobic tails face towards each other- allowing  molecules of water to diffuse across the membrane along the concentration gradient.

Thus the water will move from an area of high concentration  to an area of low concentration, until the system reaches a steady state called equilibrium- after this, there will be no net movement of water. Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

The dialysis tubing mimics a semi permeable membrane; it only allows water and small molecules of iodine to cross into the bag containing starch. The tubing is impermeable to starch;  these large molecules require the aid of protein omplexes called membrane channels, in order to move across the membrane and against the concentration gradient.
