Why are there sutures on the human skull? what does this tell you about the actual structure of the skull?

Answers

Answer 1
These sutures are actually small divisions between the bones of the skull which are used during the early stages of the human's life to give space and allow the growth of the brain and the skull. After the skull and brain are fully developed, these sutures fuse together.

These sutures helped us understand that the skull is not made of a single large bone, but rather of a number of small bones.
Answer 2
Final answer:

Sutures are specialized, fibrous joints on the skull that bind the various skull bones together, allowing for slight movement and flexibility. This indicates that the skull is not a single solid bone but comprises of interconnected bones, allowing for growth and accommodating brain expansion, particularly during infancy and childhood.

Explanation:

The sutures on the human skull are a type of specialized, fibrous joint that only occur in the skull (or cranium). They appear as zigzag lines and are essential in holding the various skull bones together.

The skull is not a single, solid bone, but is actually made up of multiple bones that are bound together by sutures. These sutures act like a very strong, almost unbreakable adhesive that holds the skull bones together. They also allow for the slight movement and flexing of the skull bones, which is particularly important during childbirth to facilitate the passage through birth canal and also to accommodate brain growth during infancy and childhood.

Therefore, the existence of sutures on the human skull signifies that the skull is made up of various interconnected bones rather than one solid piece. This aspect of the skull structure is vital for flexibility, growth, and movement in the cranium.

The ________ division of the autonomic nervous system is known as the "rest and digest" division.

Answers

The Parasympathetic division of the autonomic nervous system is known as the "rest and digest" division.
It is what controls the day-to-day "normal" functions of the body when we are not aroused, alarmed, or in a state of vigor such as exercise. For example, it keeps us breathing at a steady rate between 8-16 breaths per minute, keeps our heartrate between 60-90 beats per minute, keep blood flowing to our digestive organs and kidneys to process nutrients and filter out wastes, respectively. Hence the term "rest and digest."
It's antithetical system is the Sympathetic subdivision of the Autonomic Nervous System (ANS), which upon alarm or proper stimulus (activity): speeds up heartrate and respiratory rate, slows down digestive and kidneys function, and diverts blood from those organs (intestines and kidneys) to heart, lungs, and skeletal muscle for work and movement, aka "fight or flight."

When hot, many mammals sweat to control their body temperature. evaporation contributes to temperature moderation, but mammals' ability to control their body temperature is mainly due to __________?

Answers

The absorption of heat by the breaking of hydrogen bonds, think homeostasis or hypothalamus.

Answer:

Homeostatsis

Explanation:

Mammals are homoeothermic, which means they can adjust their body temperature as per change in temperature of the surroundings. This is called homeostasis.

Homeostasis is a self-regulatory process by which some organisms such as mammals, birds maintains their internal environment constant.

For examples, the body of a human body functions optimum at normal temperature which is  37°C. If the body temperature increases well above 37°C, then by self-regulatory process body bring down temperature to the normal.

The fibrous skeleton of the heart functions in all of these ways except in __________.

Answers

The fibrous skeleton of the heart functions in all of these ways: when the positions of the muscle fibers and valves in the heart is stabilized, when for the cardiac muscle fibers and myocardial blood vessels and nerves physical support is provided, the distribution of the muscles contraction forces are controlled. The fibrous layer is the reinforcing layer of the pericardium.

Final answer:

The fibrous skeleton of the heart does not initiate cardiac contractions, a role instead fulfilled by the SA node. Cardiac muscle tissue, composed of cardiomyocytes connected by intercalated discs, synchronizes contractions to effectively pump blood. The fibrous skeleton provides structural support, anchors heart valves, and serves as an electrical insulator.

Explanation:

The fibrous skeleton of the heart serves several functions, including providing structural support for the heart, anchoring the heart valves, thus preventing their overextension, and acting as an electrical insulator that allows for the correct timing of atrial and ventricular contractions. However, one function that it does not serve is the initiation of cardiac contractions. Instead, specialized cardiac muscle cells known as the sinoatrial (SA) node are responsible for generating electrical impulses that initiate the heartbeat.

Cardiac muscle, also referred to as heart muscle, is under involuntary control and does not require stimulation by the nervous system to contract. Unlike skeletal muscle fibers, cardiac muscle cells or cardiomyocytes are shorter, typically have a single nucleus located centrally, and feature many mitochondria and myoglobin for aerobic metabolism. Cardiomyocytes are connected via intercalated discs, enabling synchronized contractions throughout the heart muscle. These characteristics allow the cardiac muscle tissue to efficiently pump blood into the vessels of the circulatory system.

You can't test how different people see the same colors. Everyone will see something different.

Hope this helped! :)

Answer:

A.) How people experience color varies

Explanation:

This question would be hard to answer scientifically because each person has a different perception of color.

The retina, the portion of the eye responsible for capturing the image, has two groups of cells: rods and cones. Cones are the cells responsible for our color perception, and our eyes have red, blue, and green cones. However, each person carries different portions of each type of cone, generating different color perceptions. For example, a plate that you consider red may be seen as brown or pink by some people, precisely because of the difference in the proportion of the cones and how each brain receives the information.

Can someone give me a good start for an essay with the topic of "Breast Cancer"? Thank you.

Answers

There is a lot of women who are diagnosed with breast cancer every day but they usually do not know a lot about it in terms of how it forms and the many ways it can be treated. Breast cancer is a very serious disease that shouldn’t be taken lightly; if it is left untreated it can spread to other organs and eventually kill you.  Even if you do not have breast cancer, chances are that you know or will know someone who will get it, so it is imperative that people understand how breast cancer forms, know the stages of breast cancer, be familiar with who gets breast cancer and how you can possibly avert it, and understand all of the different ways to treat cancer and prevent it from coming back. 

Breast cancer always begins with a tumor much like most other forms of cancer.  As normal body cells, or DNA, grow and divide, abnormalities occur sometimes but in normal incidences, those cells are detected by the body or ribosome so the cell then repairs itself or it will disable the DNA and die. Body cells develop and divide often during the early stages of life after that cells only divide when there are cells to replace from dying or worn out cells from injuries or viruses.  Cancer cells develop from damage in DNA. Cancer cells are not detected as “abnormal,” therefore, they continue to grow and divide without being destroyed by the body.  Cancer cells have a damaged ability to bond to one another which means that the cells can’t tell each other to stop dividing when there are too many of them; they just keep trying to fill the space which results in a mass of cells forming a tumor. A tumor can either be malignant or benign.  A malignant tumor continues to grow and divides rapidly and it may become life. Hope that helped

Which two characteristics of living things do viruses exhibit PLZ HELP!!!!!!!!!!!

The two characteristics that viruses have same as that of living things are mentioned as under:-

1. They have genetic material & 5.They reproduce.

They have genetic material as either DNA or RNA like living beings. The genetic material of viruses is surrounded by capsid which is made up of proteins. Apart from this basic feature they have the ability to reproduce. They infect a host cell and take control of host's cellular machinery to reproduce. They use host's energy in the form ATP and use the host's resources to regenerate their own replicas. They are basically parasitic in nature because they infect a host and use its resources without providing it any benefit.

Rest of the options are incorrect. Viruses do not increase in size. They are acellular i.e. they are not cellular neither they eliminate wastes.

Answer:  The two characters that viruses exhibit like that of living things are :

1. Viruses have genetic material, they carry RNA or DNA as genetic material. The nucleic acid may be double or single stranded. The virus is entirely an infectious particle. which consists of virons and outer shell which is made up of nucleic acid.

2. They reproduce: Viruses during the infection process in the target host cell reproduce and produce many viruses.

In the annunciation of the death of the virgin (13.23), duccio employs an innovative use of __________.

Answers

In the annunciation of the death of the virgin 13.23, duccio employs an innovative use of architecture. During this period the most fervent development in painting occurred in Italy. At the end of the thirteenth century, Italian artist began demonstrating an astonishing genius for strikingly dramatic works. Incorporating the neo greek influences acquired from the fourth crusade with the gothic style and a bold new emotional intensity was exposed. The first major step eliminating painting from the architectural setting of other art forms can be seen in the Annunciation of the Death of the Virgin by the Sienese master, Duccio. Earlier painters always placed architectural features in arrears the figures which makes a new perspective of space and depth. While duccio, in structural space and depth on a two dimensional surface, opening a window onto a distant scene, giotto distilled these concepts of depth and space to startling simplicity drawing the viewer into a picture. 

The calvin cycle makes direct use of ________ to make ________.

Answers

The Calvin cycle makes direct use of CO2, ATP, and NADPH to make sugar.

Calvin cycle is a part of light-independent reaction from a plant that used to make carbohydrate/sugar. Since this reaction is making more complex molecules it belongs to anabolic reaction and will need energy to be done.

Final answer:

The Calvin cycle makes direct use of ATP and NADPH to make glucose and other carbohydrates. It consists of two phases: carbon fixation and reduction, where ATP and NADPH are utilized to produce GA3P.

Explanation:

The Calvin cycle uses ATP and NADPH to convert carbon dioxide into glucose, storing energy from photosynthesis. Specifically, the cycle harnesses energy in the form of 6 ATP and 6 NADPH to produce Glyceraldehyde-3-phosphate (GA3P) molecules. These molecules store the energy captured from photosynthesis. During the cycle, GA3P is used to regenerate Ribulose biphosphate (RuBP) which continues the cycle enabling the fixation of CO2.

The Calvin cycle consists of two main phases. Initially, CO2 is fixed into an organic molecule. Subsequently, ATP and NADPH from the light reactions are used to reduce the fixed carbon into GA3P, which can then be used to form sugars like glucose.

The cycle is crucial for building high-energy carbohydrates necessary for plant growth and energy storage, demonstrating how light energy is converted into chemical energy during the process of photosynthesis.

If a cell is placed inside a solution that has a higher concentration of solute than on the inside of the cell, what can be said about the movement of water?        A. Water will move out of the cell, causing it to shrivel.   B. Water will move into the cell, causing it to swell.   C. Water will move out of the cell, causing it to swell.   D. Water will move in and out of the cell at the same rate.

Answers

WATER WILL MOVE OUT OF THE CELL CAUSING IT TO SHRIVEL. This is because, the more solute a solution contain, the less its probability of crossing a semi permeable membrane into another compartment, this then result in the net flow of water from the region of lower solute concentration to the region of higher solute concentration. Thus, water will flow out of the cell which has lower solute concentration into the surrounding solution which has higher concentration. The outflow of water will make the cell to shrivel.

A network of interlacing nerve fibers in the peripheral nervous system (PNS):

Answers

A network of interlacing nerve fibers in the peripheral nervous system (PNS) is called the nerve plexus. It is a branching network of nerves. It consists of efferent and afferent fibers that are results of the anterior rami of blood vessels and spinal nerves. These nerves are for motor and sensory functions.
Final answer:

The peripheral nervous system (PNS) is the interlaced network of nerve fibers that enables communication between the brain and spinal cord (the central nervous system, or CNS) and the rest of the body. It serves a key role in transmitting sensory inputs and motor responses and comprises the sensory-somatic and the autonomic nervous systems. The PNS is vulnerable to injury and infections, which can result in neuropathy.

Explanation:

The peripheral nervous system (PNS) is a network of interlacing nerve fibers that serve as the connection between the central nervous system (CNS) and the rest of the body. The PNS consists of nerve cord-like bundles of axons that transmit both sensory inputs from the body to the CNS and motor responses from the CNS to the rest of the body. The nerves within the PNS are divided into the sensory-somatic nervous system, which manages the transmission of sensory information, and the autonomic nervous system, overseeing involuntary body functions.

The PNS operates much like the wires that connect a power source to individual houses. It carries the signals generated by the 'power plant' of the CNS, enabling these signals to control the body's functions and allowing the CNS to receive sensory information from the body. The PNS comprises bundles of axons, which, unlike the tracts in the CNS, are bound by multiple layers of connective tissue and supplied with nourishment by blood vessels.

Damage or infection to the nerves of the PNS can lead to neuropathy, resulting in sensations of tingling or numbness. The PNS and CNS are critical subsystems of the human nervous system, working interactively to maintain the communication network of the body.
