Answer:

  • Both processes form minerals.
  • Volcanic eruptions form precipitates and shifting of tectonic plates form minerals.

Explanation:

Both volcanic eruptions and the shifting of tectonic plates form minerals. Volcanoes and their eruptions can directly or indirectly lead to the formation and/or deposit of minerals such as diamonds and zinc. Shifting also forms minerals due to the forces of compression the plates apply on each other as they move past.

Volcanoes are known the cause precipitates because when the erupt, the ash that is released mixes with water vapor which then becomes rain eventually.

Answer:

A

Explanation:

A precipitate is sedimentary rock formed by the minerals in water during precipitation, Minerals are sold sediments made by the earth in both heat and pressure or when things crystalize.

Magma crystalizes once cooled therefore creating a mineral.

The pressure of tectonic plates combines sediments together creating minerals.

Which is part of the spindle apparatus?
professor190 [17]

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.

A group of single-cell organisms collected from the ocean was brought into the lab for examination. The lab assistant was concer
jolli1 [7]

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.

Suppose that at a given point along a capillary, the following forces exist: Capillary hydrostatic pressure (HPc) = 30 mmHg Inte
Ainat [17]

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:

  • Data:

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

  • Formula Applied :

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>
