When a parent cell splits to create two identical daughter cells, the process of nuclear division known as mitosis takes place in eukaryotic cells. Mitosis refers particularly to the division of the duplicated genetic material contained in the nucleus during cell division.
A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. DNA is copied or replicated prior to cell division. The chromatin is then compressed into discernible structures known as chromosomes during an early stage of cell division (KROH-muh-sohmz). Two identical components known as chromatids make up a duplicated chromosome (KROH-muh-tidz). A kind of cell division known as mitosis occurs when a single cell (the mother) splits into two genetically identical daughter cells. Mitosis, when referring to the cell cycle, is the stage of cell division during which the DNA in the cell's nucleus is divided into two identical sets of chromosomes.

!!Don't answer this ques if u don't know the answer!!
Answer:
Too Much Growth Hormone in a Child: Causes and Effects
Growth hormones are important influences on a child’s height and development. While many children are shorter or taller than others due to genetics, some children may have a growth disorder.
Growth disorders affect the speed at which a child develops. Height, weight, and sexual development are just a few features which can be affected. Diseases or problems with the pituitary gland are the leading causes of growth disorders.
The pituitary gland is responsible for producing growth hormones. Too few can lead to poor growth in children, while too many can lead to a condition called gigantism.

What is Cortex?
The cortex, also referred to as the cerebral cortex, is the region of the mammalian brain closest to the outside of the cerebrum. The anatomical term "cortex" refers to the body's outer layer. In reality, the frontal portion of the cortex, which is where higher cognitive functions are located, is where the majority of our intellect actually resides. Additionally, it is the final area of the brain to grow both developmentally and evolutionarily. The heart is the only organ in the human body without a "cortex," since others like the kidneys and ovaries also have an outer layer.
In anatomy, the outside portion or layer of a certain internal organ or tissue is often referred to as the cortex. The cerebral cortex serves as one example. The outermost layer of a vertebrate's cerebrum is called the cerebral cortex. The renal cortex is another another. The kidney's periphery is known as the renal cortex. The cortex in botany refers to the stem and root tissue that extends outward toward the vascular tissues. In some plants, it could be situated halfway between the vascular tissues and the epidermis. The cortex is found in woody plants sandwiched between the periderm and vascular tissue, particularly phloem. Therefore, the cortex is a part of the bark of the tree.

An imaginary line drawn through the body to separate it into sections and create directional terms is called a body plane. Body planes are used as a reference to describe the position and direction of body structures. They help in understanding anatomical relationships and movements within the body.
There are three main body planes commonly used in anatomy:
1. Sagittal plane: This plane divides the body into left and right halves. It runs vertically from front to back, creating a right and left side. An example of a sagittal plane is the midline that separates the nose into two equal halves.
2. Frontal (coronal) plane: This plane divides the body into front (anterior) and back (posterior) portions. It runs vertically from side to side, creating a front and back side. For instance, a cut across the chest from shoulder to shoulder would be in the frontal plane.
3. Transverse (horizontal) plane: This plane divides the body into upper (superior) and lower (inferior) parts. It runs horizontally, creating an upper and lower section. A transverse plane could be represented by a line drawn across the waist.
By using body planes, medical professionals can accurately describe the location, orientation, and movement of body structures. Understanding these planes is essential for effective communication in healthcare and anatomical studies.

the electrical event that begins each heartbeat occurs at the sinoatrial (sa) node. true or false?
The statement "The electrical event that begins each heartbeat occurs at the sinoatrial (sa) node" is true.
The electrical event that initiates each heartbeat occurs at the sinoatrial (SA) node, which is located in the right atrium of the heart. The SA node acts as the natural pacemaker of the heart, generating electrical impulses that spread through the atria, causing them to contract.
This electrical signal then travels to the atrioventricular (AV) node, which is responsible for conducting the electrical impulse to the ventricles, resulting in their contraction. The coordinated contraction of the atria and ventricles allows for the pumping of blood throughout the body.
Therefore, the SA node plays a crucial role in initiating the electrical activity that regulates the heartbeat.

The three layers of the ureter's wall are the inner mucosa layer, the middle muscular layer, and the outer Adventitia layer. Muscular waves help propel urine through the ureters to the urinary bladder, where it passes through a flaplike valve in the mucous membrane.
Inner Mucosa: The innermost layer is the mucosa, which is composed of transitional epithelium. This layer lines the inside of the ureter and helps prevent urine from leaking back into the kidneys.
Middle Muscular Layer: The middle layer is the muscular layer, consisting of smooth muscle fibers. These muscles contract in wave-like motions (peristalsis) to propel urine from the kidneys to the urinary bladder.
Outer Adventitia: The outermost layer is the adventitia, which is a fibrous connective tissue layer. It provides structural support and protection to the ureter.
As urine reaches the urinary bladder, it passes through a flap-like valve called the ureterovesical valve, which is located in the mucous membrane of the bladder. This valve prevents urine from flowing back up into the ureters and kidneys.
