Which of these is not a property of lymphatic capillaries?
Inessa05 [86]

Answer:

They are smaller than blood capillaries.

Explanation:

Lymphatic capillaries drains the extracellular fluid present between the cell spaces. The fluid is known as lymph as it enters the lymph capillaries. These capillaires drains into lymph vessels that drains to lymph nodes and lymph ultimately enters the venous circulation.

Lymphatic capillaries are slightly larger than blood vessels and these capillaries have close ends. The walls of lymph capillaries are made up  of endothelial cells. The endothelial cells overlap in lymph vessels and when the pressure in ECF is greater these cells move and create a sort of gap for the movement of ECF inside the lymph capillary but when the pressure inside the capillary is greater these cells again overlap and does not allow the lymph to move outside of capillary. Thus lymph capillaries only allow the ECF to enter the capillary but does not allow the lymph to go out from capillary. Lymph capillaries have greater internal pressure than blood vessels.

How does the nucleotide sequence determine the protein structure and function of a cell?
Montano1993 [528]

Answer:

The four bases A, T, C and G make up the genetic code. The base sequence determines amino acid sequence in protein. Messenger RNA (mRNA) is a molecule which carries a copy of the code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids.

Why is oxygen consumption a good measure of respiration in yeast?
Dafna1 [17]

Answer:

The respiration of a suspension of yeast cells was measured by determining the decrease in pressure of the gas above the cell suspension. The apparatus was arranged so that the gas was confined to a constant volume, 16 cm3 and the entire pressure change was caused by the uptake of oxygen by the cells. The pressure was measured in a monometer, the fluid of which had a density of 1.034 g/cm3. The entire apparatus was immersed in a thermostat at 37. In a 30 minute observation period the fluid in the open side of the manometer dropped 37mm. Neglecting the solubility of oxygen in the yeast suspension, compute the rate oxygen consumption by the cells in mm3 of O2 (STP) per hour
