Using repetition and deliberate practice to master skills and habits is essential to ________ memories.

Answers

The appropriate response is procedural memories. Procedural memory is a piece of the long haul memory that is in charge of knowing how to get things done, otherwise called engine aptitudes. As the name infers, procedural memory stores data on the best way to play out specific methods, for example, strolling, talking and riding a bicycle.
Final answer:

Using repetition and deliberate practice helps move information from short-term to long-term memory, aiding the formation of long-term memories. Techniques like elaborative rehearsal, chunking, and mnemonic devices can enhance this process.

Explanation:Repetition and Deliberate Practice in Memory Formation

Using repetition and deliberate practice to master skills and habits is essential in cementing long-term memories. This process involves moving information from short-term memory to long-term memory through active rehearsal. For example, when children learn their ABCs by singing the alphabet song over and over again. Additionally, procedural memories such as skills for riding bicycles or driving are also developed over time through repetition and practice.

Methods like elaborative rehearsal can enhance memory. This technique involves linking new information to already stored knowledge and repeating it. Lastly, another helpful strategy is chunking, where you organize information into manageable bits or chunks, such as breaking up a phone number into area codes and smaller groups of numbers.

Mnemonic devices are another effective method for aiding memory. They are especially useful when we want to remember larger pieces of information such as the order of planets in a solar system or steps of a complex mathematical operation.

Rebecca, who is African American is most apt to experience menarche first.

What do you mean by menarche?

Menarche defines the onset of menstruation, which is a normal physiologic process that occurs at regular monthly intervals. Menarche typically occurs around age 12 but a few years earlier or later is completely normal. Menarche happens during a time of physical and sexual maturation in adolescence known as puberty.

Moreover, menarche is defined as the first menstrual period in a female adolescent. Menarche typically occurs between the ages of 10 and 16, with the average age of onset being 12.4 years.

Therefore, it is the stage of initiation of menstruation in the life of a female girl. it generally occurs at an age of 11-13 years. It refers to the beginning of the reproductive phase in girls.

How do single celled organisms, like paramecium, adapt to living in a hypotonic environment?

Answers

I believe it helps it remove excess water and prevent swelling.

Osmoregulation is a process through which do single celled organisms, like paramecium, adapt to living in a hypotonic environment.

Through a process known as osmoregulation, single-celled organisms like Paramecium adjust to life in a hypotonic environment. Osmoregulation is the control of the concentrations of water and solutes within an organism in order to preserve internal equilibrium or homeostasis.

In a hypotonic setting, the surrounding solution's solute concentration is lower than that of the Paramecium cell's cytoplasm. As a result, a concentration gradient is created where water seeks to enter the cell, possibly resulting in cell rupture or excessive swelling.

Contractile vacuoles are specialized structures seen in Paramecium. These vacuoles periodically contract, discharging the stored water from the cell, collecting extra water that enters the cell through osmosis. Through this procedure, excessive swelling is prevented, and the water balance is controlled.

Hence, osmoregulation is a process through which do single celled organisms, like paramecium, adapt to living in a hypotonic environment.

Which of these energy resources was not created by by the Sun's energy? petroleum uranium coal

Answers

Uranium was not created by the Sun's energy.

The nuclear fusion occurred in the Sun is the responsible for the nucleosynthesis, which means the creation of elements, this is the formation of heavier nuclei from the fusion of lighter nuclei.

The heavier the element the higher the energy and temperature required. The Sun's temperature is enough for the sinthesis of lighter element. Elements from oxygen to iron require much more temperature. And elements heavier than iron (which includes uranium) needs the energy from the explosion of a Supernova.

So, the answer is uranium.

Chloroplasts are found in __________. chloroplasts are found in __________. neither plant cells nor animal cells animal cells only both plant cells and animal cells plant cells and some protists

Answers

Plant cells and some Protists

Answer:

 The correct answer about this question is PLANT CELLS AND SOME PROTISTS.

Explanation:

  Chloroplasts are organelles present in the cells of plants and other photosynthetic organisms such as algae. Algae belong to the Protista kingdom. However, in the protist kingdom there are also protozoa, which do not have the presence of chloroplasts, as they are heterotrophic beings, that is, they do not produce their food and do not have chloroplasts. Unlike algae, which present chloroplasts and perform photosynthesis.

  Main characteristics of chloroplasts:

- They are green in color due to the presence of chlorophyll. This compound wrote before is one of the responsible for photosynthesis.

- They are limited by a kind of envelope formed by two lipoprotein membranes.

- It has inside it a liquid known as stroma.

- They have DNA, RNA and ribosomes. Thus, they have the ability to perform the process of protein synthesis and multiply.

Gee's arm was cut during an industrial accident. the blood was pouring from the wound in spurts. which type of vessel was severed?

Answers

Final answer:

The blood vessel likely severed causing blood to spurt out in Gee's injury is an artery, due to the high pressure at which arteries carry oxygen-rich blood from the heart. Immediate measures to control bleeding and seeking medical attention are crucial, and the body's automatic response includes a vascular spasm to reduce the bleeding.

Explanation:

The type of vessel that was likely severed in Gee's arm if the blood was pouring out in spurts is an artery. Arteries are blood vessels that carry oxygen-rich blood away from the heart at high pressure. This high pressure often results in blood spurting out rhythmically with the heartbeat when an artery is cut. In comparison, veins carry blood back to the heart at a lower pressure, and bleeding from a severed vein presents as a steady flow, rather than spurting.

In the case of a severe injury where an artery is severed, it is critical to control the bleeding and seek medical attention immediately to prevent severe blood loss. Emergency medical techniques such as applying pressure to the wound, using a tourniquet, or clotting agents may be employed until professional medical help is provided.

Vascular spasm is a body's natural response to injury where the smooth muscle in the walls of the blood vessel contracts to reduce blood flow and minimize bleeding. However, this is typically insufficient to deal with severe arterial bleeding, and further intervention is necessary.

A sudden, loud noise will reflexively cause the tensor tympani muscle to __________ and cause the stapedius muscle to __________.

Answers

A sudden, loud noise will reflexively cause the tensor tympani muscle to contract, pulling on the malleus ossicle (tiny bone), and cause the stapedius muscle to contract, pulling up on the stapes ossicle.
When presented with a high-intensity sound stimulus, these two muscles contract, known as the acoustic (auditory) or stapedius reflex. The reflex decreases the transmission of vibrational energy to the cochlea, where it is converted into electrical impulses to be transmitted to the brain via the auditory nerve to then be processed.

Assume that a mutation occurs in a human population that produces a horn (like a unicorn) in the middle of the forehead. further assume that the horn is inherited as a y-linked trait in humans. a man with the horn has a daughter who has a son with a man who has lacks the horn. what is the probability that the horned man's grandson also has a horn?

Answers

0% that the offspring will have a horn. Since the mutation is y-linked, that means that the carrier of the mutation has to have a y chromosome. Since the man's child is a daughter, that means that she didn't get the mutated y chromosome. So none of her children will get the mutation from her father. And since the father of the grandchild doesn't have the mutation, that means that the child can not have the mutation. Hence, there's a 0% chance of the grandchild having the mutation.
