What is a consequence of the specific heat capacity for liquid water, ice and water vapor

Water has unique chemical characteristics in all three states—solid, liquid, and gas—thanks to the ability of its molecules to hydrogen bond with one another. Since living things, from human beings to bacteria, have a high water content, understanding the unique chemical features of water in its three states is key to biology.

In liquid water, hydrogen bonds are constantly being formed and broken as the water molecules slide past each other. The breaking of these bonds is caused by the energy of motion (kinetic energy) of the water molecules due to the heat contained in the system.

When the heat is raised (for instance, as water is boiled), the higher kinetic energy of the water molecules causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas. We observe this gas as water vapor or steam.

On the other hand, when the temperature drops and water freezes, water molecules form a crystal structure maintained by hydrogen bonding (as there is too little heat energy left to break the hydrogen bonds). This structure makes ice less dense than liquid water.

lora16 [44]

Answer:

The claim by the researcher is supported because of the known functions of insulin and growth factors. Both hormones have a tendency to respond to the presence of glucose. The growth hormone initiates STAT5 signaling for producing the Igf-1 factor that is important for utilizing glucose. The insulin hormone is well known for utilizing glucose.

xeze [42]

The word "cycle" in cell cycle refers to the regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells.
The cell cycle is the term that describes the development and growth of a cell, after its formation and until its reproduction (division into two daughter cells). In eukaryotic cells (cells that include a nucleus) the cell cycle is comprised of two major phases, the interphase and the mitosis. During interphase, the cell grows larger and duplicates its genetic material. During mitosis, the cell divides its genetic material and cytoplasm, creating two daughter cells.

In the first 2.5 hours after a radical neck dissection, 40 ml of medium-red, bloody fluid is obtained from the client's drainage

cluponka [151]

The nurse should assess the patient vital sign and notify the healthcare provider. For 2.5 hour after neck dissection, production of 40ml by the drainage is a bit excessive. There might be a bleeding in the site of operation that becomes the source of the drainage. Change dressing will not do anything. Applying pressure can be done if the site of bleeding is known.

The fact that plants can be cloned from somatic cells demonstrates that _____.A) differentiated cells retain all the genes of th

mojhsa [17]

Answer:

The correct answer is A) differentiated cells retain all the genes of the zygote

Explanation:

A plant can be cloned from the somatic cells which shows that the differentiated cell of plants have the ability to divide and differentiate to produce a new plant. This property of the cell is called totipotency.

All the cells in plants are not totipotent but some cells under proper condition can show the property of totipotency. Totipotency property shows that the differentiated cell is having all the genes that were present in the zygote.

This property of plant cells is used by scientist in plant tissue culture to produce plants for research and other purposes. So the right answer is A.
