Make a claim about homologous structure help scientist interpret theory of evolution​

Answers

Homologous structures are structures that we find across different species. They have the same organisation (they have the same parts) but have different functions (they are used for different things).

homologous structures can be used to interpret evolution, because they show that different species share common features which must have been inherited from a common ancestor.

These structures have a different function because different species use these parts for different purposes. This supports evolution by supporting the claim that organisms adapt (change) in response to their environment.

Radiocarbon dating

Explanation:

Radiocarbon dating is a technique for determining the age of carbon-based materials derived from live beings. By measuring the quantity of carbon-14 in a sample and comparing it to an internationally accepted reference standard, an age may be determined. Radiocarbon dating is based on the basic principle that all living organisms absorb carbon from the atmosphere and food sources around them, including a small quantity of naturally radioactive carbon-14. When a plant or animal dies, it stops absorbing carbon, but the radioactive carbon it has stored decays.

How are water molecules able to bond to each other?

Answers

Water has a remarkable ability to cling to itself and other substances. The propensity of water molecules to be attracted to other water molecules, allowing water to be a "sticky" liquid, is described by the property of cohesion.

Which bond is present between water?

The difference in charge between slightly positive hydrogen ions and other, slightly negative ions causes hydrogen bonds, which are electrostatic forces.

Hydrogen bonds form between adjoining hydrogen and oxygen atoms of adjacent water molecules in the case of water. A hydrogen bond is formed when individual water molecules attract each other.

Blood -- d) transport O2, CO2 and nutrients. Arteries -- c) carry blood away from the heart.Veins -- a) carry blood back to the heart and lungs.Cappilaries -- b) connect Arteries and veins._______________Blood helps in the transportation of oxygen , Carbondioxide and nutrients. Arteries are the vessels which carry blood away from the heart to various organs of the body. since the blood emerges from the heart under high pressure, the Arteries have thick , elastic vessels. Veins collect the blood from different organs and bring it back to the heart . They do not need thick walls because the blood is no longer under pressure, instead they have valves that ensures the blood flows only in one direction. Arteries divide into very fine vessels called Cappilaries. Which bring the blood in contact with the individual cells . These Cappilaries have one cell thick walls which help in exchanging of material between the blood and surrounding cells . The Cappilaries then join together to form veins that convey the blood away from oragn to tissue.

What is the capacitance per square centimeter of such a cell wall?.

Answers

Cell membranes (the walled enclosure around a cell) are typically about d = 7.1 nm thick. They are partially permeable to allow charged material to pass in and out, as needed. Equal but opposite charge densities build up on the inside and outside faces of such a membrane, and these charges prevent additional charges from passing through the cell wall. We can model a cell membrane as a parallel-plate capacitor, with the membrane itself containing proteins embedded in an organic material to give the membrane a dielectric constant of about 12.
