Answer:

The node therefore represents the end of the ancestral taxon and the stems , the species that split from the ancestor. The two taxa that split from the node are called sister taxa.

An element has an atomic mass number of 16 and an atomic number of 7. what is the elements protons and neutrons?

damaskus [11]

Answer:

7 protons, 7 neutrons (READ EXPLANATION)

Explanation:

The atomic number represents how many protons are in an element. Generally speaking, elements have the same number of protons and neutrons. So, an element with the atomic number of 7 will have 7 protons and 7 neutrons.

However it is possible for an element to have a differing number of neutrons (an element will always have the same number of protons because that number is how the element is identified in the first place). Elements that have a number of neutrons that is not the same as the atomic number are called isotopes.

Distinguish the types of forgetting: anterograde amnesia, retrograde amnesia, encoding failure, retrieval failure, and interfere

Karo-lina-s [1.5K]

Answer:

Anterograde amnesia is the inability to create new memories after the onset of amnesia, while memories from before the event remain intact. Brain regions related to this condition include the medial temporal lobe, medial diencephalon, and hippocampus. Anterograde amnesia can be caused by the effects of long-term alcoholism, severe malnutrition, stroke, head trauma, surgery, Wernicke-Korsakoff syndrome, cerebrovascular events, anoxia, or other trauma. Retrograde amnesia is the inability to recall memories made before the onset of amnesia. Retrograde amnesia is usually caused by head trauma or brain damage to parts of the brain other than the hippocampus (which is involved with the encoding process of new memories). Brain damage causing retrograde amnesia can be as varied as a cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. The there is encoding failure. Encoding is the process of converting sensory input into a form able to be processed and stored in the memory. However, this process can be impacted by a number of factors, and how well information is encoded affects how well it is able to be recalled later. On the other hand, retrieval failure is the failure to recall information in the absence of memory cues. Proactive interference occurs when old memories hinder the ability to make new memories. In this type of interference, old information inhibits the ability to remember new information, such as when outdated scientific facts interfere with the ability to remember updated facts. This often occurs when memories are learned in similar contexts, or regarding similar things. It’s when we have preconceived notions about situations and events, and apply them to current situations and events.Retroactive interference occurs when old memories are changed by new ones, sometimes so much that the original memory is forgotten. This is when newly learned information interferes with and impedes the recall of previously learned information. The ability to recall previously learned information is greatly reduced if that information is not utilized, and there is substantial new information being presented. This often occurs when hearing recent news figures, then trying to remember earlier facts and figures.

There is an error in the above model.

ollegr [7]

ATP hydrolysis is the lysis of the molecule mediated by water. It releases a phosphate group and energy. It is a reversible reaction. (a) Reversible ATP hydrolysis. (b) added energy on the left and released energy on the right.

------------------------

ATP is a significant molecule involved in many of the cellular metabolic routes. These metabolic processes can either form it or break it.

ATP provides energy to many different functions in the organism.

ATP means adenosine tri-phosphate. It is composed of adenosine (an adenine plus a ribose), and three phosphate groups.

Note: you can also find adenosine Diphosphate (two phosphates) and adenosine monophosphate (one phosphate).

Oxygens from the phosphate groups only have a single bond to phosphate (there are no hydrogen bonds).

These single bonds, known as phophoanhydrid bonds, have a negative charge and tend to repel each other, making the molecule unstable.

So phosphate groups repel each other, and a considerable amount of energy is applied to keep them united. So phophoanhydrid bonds are high energetic bonds.

The forces that keep the phosphate groups together accumulate potential energy.

If these bonds are broken, part of this potential energy would be released.

When talking about breaking the molecule, we are referring to ATP hydrolysis. And the released energy is used in different cellular processes that require energy.

ATP Hydrolysis is the molecule lysis mediated by a water molecule.

ATP + H₂O ⇄ ADP + Pi + Energy

Pi is the released inorganic phosphate group.

This is a reversible reaction, meaning that the ADP can go back to ATP.

ADP + Pi + Energy ⇄ ATP + H₂O

(a) What is this a model of?

This model represents the reversible ATP hydrolysis.

In the superior part of the image, we can see an ATP molecule composed of adenine, ribose, and three phosphate groups. The yellow star behind represents the accumulated energy.

When ATP hydrolysis, it loses a phosphate group and part of the energy that was keeping this group in the molecule.

An ADP is composed after hydrolysis. We can see this molecule in the inferior area of the image.

ADP molecule is composed of adenine, ribose, and two phosphate groups.

Because hydrolysis is a reversible process, by adding a new phosphate inorganic group and energy, we can get a new ATP.

(b) Explain how you would change the model to make it correct?

What is wrong with this model is that instead of showing released energy during the hydrolysis process, it shows energy added to the reaction.

In the same way, instead of showing added energy to the reversible reaction, it shows released energy.

Added energy and released energy must be changed.

Added energy should be on the left
Released energy should be on the right
