Which of the following statements is true about the structure of the cell membrane?

Biology
1 answer:
miskamm [114]3 years ago
4 0

Answer:

The correct answer is:

The two layers of the plasma membrane are identical.

Explanation:

The plasma membrane is called a lipid bilayer because it is composed of two layers of cells and it makes the boundary of cell.

The other three statements are false because

Plasma membrane is semipermeable i.e it allows the transport of materials inside and outside the cell.

The proteins in the plasma membrane are integral proteins

The proteins in the plasma membrane are extensively folded and protruding from the membrane are in contact with inside and outside the cell.

If the diameter of the afferent arterioles leading to the glomerulus increases (vasodilation) net filtration pressure will incre
Vinvika [58]

True. If the diameter of the afferent arterioles leading to the glomerulus increases due to vasodilation, which ultimately increases the net filtration pressure.

The filtration of blood occurs in the kidney, an excretory organ. The kidney is composed of numerous small units called nephrons, which is responsible for the blood filtration.

Glomerulus is part of nephron and the glomerular filtration occurs in the renal corpuscle of the kidney. This process is driven by hydrostatic and colloid osmotic pressure.

These pressures are collectively called net filtration pressure, which is influenced by the diameter of afferent arterioles.

If the arterioles constricts, net filtration pressure will decrease and if arterioles dilates, net filtration pressure will increase. This mechanism is regulated by neural, renal and hormonal regulation.

The hypothesis that germs desease is theory Before many scientists believed in the idea spontaneres the appearance of organists
il63 [147K]

Explanation:

The Germ Theory of Disease  indicates that microbes are the causal agents in human disease.  In modern healthcare, Germ Theory has led to a breakthrough in the treatment of infectious diseases with antibiotics such as penicillin, and the prevention of disease outbreaks through proper sanitation and vaccination.

Further  Explanation:

Biology's unifying principle states that cells are the basic units of biological organisms. Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns. All living things, grow, respire, reproduce etc. these processes are carried out by cells, which are thus integral to their survival.

Before the discovery of cells by Robert Hooke in 1665 with a simple microscope, many scientists had long believed that life rose spontaneously over extended periods of time. Circa 1668 Francesco Redi, challenged the idea of spontaneous generation of maggots from rotting meat by placing meat in various sealed open, partially sealed and sealed containers. Sealed containers did not show the presence of maggots, and he theorized that these were likely from eggs laid on the meat by flies. This was the development of the theory disproving abiogenesis (cells arise from other living cells); this eventually proved the unifying principle we know today.

Cell theory states that living things are comprised of cells, as their smallest units capable of functioning. Microscopy helps to prove this, as cells and their varying components can readily be seen, observed and later classified.
