I believe, for the artery, they have, an open, circular lumen an a thick media
Veins on the other hand, have somewhat collapsed lumen and a thinner media. Arteries are blood vessels that carry blood out of the heart to other parts of the body, all arteries carry oxygenated blood except the pulmonary artery which carries deoxygenated blood from the heart to the lungs. Veins carry blood from other body parts to the heart, all veins carry deoxygenated blood except the pulmonary vein which caries oxygenated blood from the lungs to the heart.

The correct answer is "his primary caregiver can calm him down easily after being separated".

Starting at 6 months of age up to the age of 2 years old, a child may experience what we called separation anxiety. At this age, the child is able to represent in its mind that what he cannot see does not exist. This is manifested by signs of extreme neediness of the child. When the child eventually outgrows this phase, then the child is now securely attached and the caregiver can calm him down easily after being separated.

The human capacity for storing long-term memories is

Answers

I believe the human capacity for storing long-term memories is essentially unlimited.  Human brain consist of about a billion neurons. Neurons combine such that each one helps with many memories at a time, exponentially increasing brain's memory storage capacity to something closer to around 2.5 million gigabytes. Information entering the brain may enter the short term memory and some of it is transferred to the long-term memory.

The human capacity for storing long-term memories is around 2.5 petabytes.

The human capacity for storing long-term memories is vast and difficult to quantify precisely. The brain has a remarkable ability to store an immense amount of information over a lifetime.

While it is challenging to provide an exact measure of storage capacity, estimates suggest that the human brain may have the potential to store around 2.5 petabytes of information.

Thus, the capacity for long-term memory storage is not solely determined by the storage space but also involves various complex processes in the brain.

The cell shown above is forming a cleavage furrow as the first stage of cytokinesis. To which organism does the cell pictured likely belong?


Answers

Final Answer:

The cell shown forming a cleavage furrow as the first stage of cytokinesis likely belongs to a multicellular organism, specifically an animal.

Explanation:

The process of cytokinesis, specifically the formation of a cleavage furrow, is a characteristic feature of animal cells undergoing cell division. This distinct mechanism is employed by animal cells to complete the process of cell division during mitosis and meiosis. The cleavage furrow is formed as a result of the contraction of the actin-myosin ring, leading to the physical separation of the two daughter cells. This mechanism is not observed in plant cells, which typically form a cell plate during cytokinesis.

Therefore, based on the presence of a cleavage furrow, we can confidently conclude that the cell in question is from an animal organism.Animal cells exhibit unique features during cell division, such as the absence of a rigid cell wall and the involvement of microfilaments in the formation of the cleavage furrow. The contractile ring, consisting of actin and myosin filaments, contracts and pinches the cell membrane, resulting in the formation of two distinct daughter cells.

This process is vital for the growth and development of multicellular animals. In contrast, plant cells, which possess a rigid cell wall, form a cell plate to divide during cytokinesis. Therefore, the identification of a cleavage furrow is a key indicator that the cell belongs to an animal organism, highlighting the importance of understanding the unique characteristics of cell division mechanisms in different organisms.

The brain grows the most rapidly during the first ________ years of life

Answers

The brain grows the most rapidly during the first months and years of life. During first months and years rapid growth and refinement in axons, dendrites, and synapses occur, especially in the cortex. A child's brain undergoes an amazing period of development from birth to to three- producing more than a million neural connections each second. The development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
Final answer:

The brain grows the most rapidly during the first few years of life. Research suggests that neural connections and pathways occur during this period of rapid growth. The brain becomes more complex, efficient, and functional during childhood and adolescence.

Explanation:

The brain grows the most rapidly during the first few years of life. Research suggests that the majority of neural connections and pathways occur during this period of rapid growth, known as blooming. This growth is followed by a period of pruning, where neural connections are reduced to make the brain function more efficiently. By the age of six, the brain has already attained about 90 percent of its adult size. During the first few years of life, the frontal lobes, which are associated with planning, reasoning, memory, and impulse control, grow rapidly. Overall, the brain becomes more complex, efficient, and functional during childhood and adolescence.

When ibuprofen is given for fever to children 6 months of age up to 2 years, the usual dose is 5 milligrams (mg) per kilogram (kg) of body weight when the fever is under 102.5 degrees fahrenheit. how much medicine would be usual dose for a 18 month old weighing 18 pounds?

Answers

Answer:

45mg

Explanation:

Final answer:

The usual dose of ibuprofen for an 18-month-old weighing 18 pounds would be approximately 40.8233 mg.

Explanation:

To calculate the usual dose of ibuprofen for a child between 6 months and 2 years old, you need to convert their weight from pounds to kilograms. Since 1 kilogram is equal to 2.20462 pounds, you can use this conversion factor to find the weight in kilograms. In this case, the 18-month-old weighs 18 pounds, which is approximately 8.16466 kilograms.

Now, you can calculate the usual dose by multiplying the weight in kilograms by 5 milligrams per kilogram. So, for an 18-month-old weighing 18 pounds, the usual dose would be:

Usual dose = 8.16466 kg * 5 mg/kg = 40.8233 mg

What causes the speed of seismic waves to change

Answers

Seismic waves change speed as they travel through Earth because of the four different layers. The layers differ, changing from a thin crust, to a rocky mantle, a liquid outer core, and finally a solid metallic core. Each of the layers affect the speed of seismic waves due to the differences in their makeup
 hope this helps.

Final answer:

Seismic waves experience changes in speed depending on the material they pass through, with denser and more rigid materials causing faster travel and partially melted or liquid materials slowing or stopping certain waves. Variations in rock density, elasticity, and state due to depth-induced compression and temperature changes are also key factors.

Explanation:

The speed of seismic waves changes as they travel through different materials due to variations in density, elasticity, and state of the materials. Factors such as the level of rock compression, which increases with depth, affect velocity; hence, waves move faster through denser and more rigid materials. Refraction also plays a role, as the increase in density and seismic velocity with depth causes seismic rays to curve and bend toward the earth's surface. This effect is seen in the mantle, where seismic waves travel faster through cooler, denser rocks than through warmer, less dense rocks.

Furthermore, the physical state of the material significantly influences wave speed. For instance, when seismic waves encounter partially melted or liquid regions, P-waves are slowed significantly and S-waves are stopped altogether. Therefore, seismic wave speed can be a powerful tool for geologists to understand Earth's interior structure, using changes in wave speed to infer the presence of different materials and states within the planet.

Which organism is most likely to be responsible for the boils? which organism is most likely to be responsible for the boils? bacillus cereus escherichia coli staphylococcus aureus staphylococcus epidermidis?

Answers

The answer is Staphylococcus aureus.


Boil (furuncle) presents skin infections, usually associated with infections near the root of the hair or the sebaceous gland. The most common causative agent of boils is Staphylococcus aureus, a penicillin-resistant bacteria. It is formed by pushing the bacteria in one place in the skin, which results in the creation of pus.  A boil is most often the result of insufficient skin hygiene (if the skin is unevenly cleaned), then accidental and invisible damage that is not treated in a timely manner.
