C) What does this cladogram tell you about the evolutionary relationship of the traits of jaws

schepotkina [342]

Answer:

In biology, a cladogram can be described as a diagram which shows evolutionary relationships among different organisms. A cladogram shows which organisms share evolutionary history and which organisms are more closely related to one another.

The cladogram in the above picture shows that the limbs originated after the jaws.

The cladogram shows that amoeba was a common ancestor to sponges, earthworms, salmon, lizards, kangroo and cats.

A) Compare and contrast diffusion, passive transport (diffusion & facilitated), primary active transport and secondary activ

zheka24 [161]

Answer:

Passive transport: It does not need any energy to occur. Happens in favor of an electrochemical gradient. Simple diffusion and facilitated diffusion are kinds of passive transport.

Simple diffusion: molecules freely moves through the membrane.

Facilitated diffusion: molecules are carried through the membrane by channel proteins or carrier proteins.

Active transport needs energy, which can be taken from the ATP molecule (Primary active transport) or from a membrane electrical potential (Secondary active transport).

Explanation:

Diffusion: This is a pathway for some small polar hydrophilic molecules that can freely move through the membrane. Membrane´s permeability depends on the size of the molecule, the bigger the molecule is, the less capacity to cross the membrane it has. Diffusion is a very slow process and to be efficient requires short distances and pronounced concentration gradients. An example of diffusion is osmosis where water is the transported molecule.

Facilitated diffusion: Refers to the transport of hydrophilic molecules that are not able to freely cross the membrane. Channel protein and many carrier proteins are in charge of this passive transport. If uncharged molecules need to be carried this process depends on concentration gradients and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an electrochemical gradient. The glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.

Simple diffusion and facilitated diffusion are passive transport processes because the cell does not need any energy to make it happen.

Active transport occurs against the electrochemical gradient, so it does need energy to happen. Molecules go from a high concentration side to a lower concentration side. This process is always in charge of carrier proteins. In primary active transport the energy needed comes from the ATP molecule. An example of primary active transport is the Na-K bomb. In secondary active transport, the energy comes from the membrane electric potential. Examples of secondary active transport are the carriage of Na, K, Mg metallic ions.

Which health care provider assessment technique does the nurse anticipate being used to determine developmental dysplasia of the

Arlecino [84]

A nurse can identify possible developmental dysplasia of the hip (DDH) during a newborn assessment through asymmetry of the gluteal folds. Asymmetrical buttock creases can suggest hip dysplasia in infants but an ultrasound or x-ray study will need to be done to determine whether the hips are normal or not just like a hip click.
