Chromatin is a part of the spindle apparatus
Explanation:
Chromosome is not only responsible for genetic material. Chromatin is that substance which consists of protein and DNA. Here DNA carries genetic instruction. Histones are main proteins of chromatin. It is also called the packaging of element for the DNA.
In two forms chromatin exist. One is euchromatin and another is heterochromatin. Euchromatin is less condensed and it can be transcribed. Heterochromatin is highly condensed and typically not transcribed. Chromosomal pathway regulates spindle assembly.
The correct answer is C. She added water that was hypotonic to the culture of organisms, and they ruptured.
Explanation:
In biology, a hypotonic solution is a substance with less concentration than the inner concentration in cells, this is the opposite of a hypertonic solution that has a higher concentration. Additionally, if cells are in hypotonic solution water or liquid will begin to get into them and this would make cells burst and finally explode and die due to the pressure in them.
This occurred in the case presented as it is likely the organisms collected from the ocean had a high concentration and therefore hen they were exposed to clean water in which concentration was lower, water entered into the cells and made them explode, which explains the only remains of them were bit and pieces.
Answer:
Suppose that at a given point along a capillary, the following forces exist: Capillary hydrostatic pressure (HPc) = 30 mmHg Interstitial fluid hydrostatic pressure (HPif) = 0 mmHg Capillary colloid osmotic pressure (OPc) = 25 mmHg Interstitial fluid colloid osmotic pressure (OPif) = 2 mmHg. The net filtration pressure at this point in the capillary is <u>7mmHg.</u>
Explanation:
Capillary hydrostatic pressure (HPc) = 30 mmHg
Interstitial fluid hydrostatic pressure (HPif) = 0 mmHg
Capillary colloid osmotic pressure (OPc) = 25 mmHg
Interstitial fluid colloid osmotic pressure (OPif) = 2 mmHg
Net filtration pressure= hydrostatic pressure gradient - Oncotic pressure gradient
Hydrostatic pressure gradient = Capillary hydrostatic pressure - Interstitial hydrostatic pressure = 30mmHg - 0 mmHg = 30 mmHg
Oncotic pressure gradient = Capillary colloid osmotic pressure - Interstitial fluid colloid osmotic pressure =25 - 2 = 23 mmHg
Net filtration pressure= hydrostatic pressure gradient - Oncotic pressure gradient = 30 mmHg - 23 mmHg = 7 mmHg.
Hence, The net filtration pressure at this point in the capillary is <u>7mmHg.</u>
