why do forensic labs analyze non-coding dna and not genes
Answer:
Why do you think forensic labs analyze non-coding DNA and not genes (i.e. sequences coding for hereditary characteristics)? Because non coding DNA are the polymorphic sequences that differ in different humans. ... The sample of DNA obtained at a crime scene and the suspect's DNA samples contain the target sequence.

Disease or disorder that affects the nervous systems
Answer:
There are many diseases/disorders that affect the nervous system, but here are a few:
Alzheimer's disease
Parkinson's disease
Epilepsy
Stroke
Explanation:
Alzheimer's disease: Alzheimer's disease is a progressive disease (gets worse and worse overtime) that destroys your memory. When a person has Alzheimer's disease, their neurons (nerve cells) get damaged and eventually die all throughout the brain. Some problems people with this disease can experience are: getting lost easily, personality/behavior changes, memory loss (obviously), and need help with self-care and daily things.
Parkinson's disease: Parkinson's disease is a progressive disorder that affects one's movement. Because the nerve cells are damaged, the dopamine (type of neurotransmitter) levels decrease. Since dopamine can control your body movement, it makes it hard to balance, and you're usually stiff. It usually begins with a tremor in your hand.
Epilepsy: Epilepsy is a neurological disorder where neuron activity in the brain gets disturbed, resulting in a seizure. Epilepsy is usually genetic or gained through a trauma or stroke (brain injuries). During these seizures, people often lose consciousness. Most epileptic people are sensitive to lights (flashing and flickering especially).
Stroke: A stroke occurs when your blood supply to your brain is interrupted/stopped. This is a SERIOUS emergency. Cells can die from lack of blood and the resulting lack of oxygen. Most warning signs of a stroke include: numbness + weakness, trouble speaking, loss of balance, and dizziness.
Why does water have a strong surface tension and why is this important?
The stronger the cohesive force, the stronger the surface tension. The water molecule has two hydrogen atoms bond to an oxygen atom through covalent bonding. ... Formed bonds are called hydrogen bonds which lead to strong cohesive forces between the water molecules and high surface tension of water.
Why is it important?The surface tension of water provides the necessary wall tension for the formation of bubbles with water. The tendency to minimize that wall tension pulls the bubbles into spherical shapes. Surface tension and droplets: Surface tension is responsible for the shape of liquid droplets.

what is excretion meaning
Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life.
In simple terms, the process of eliminating or expelling waste matter.

A human has 46 chromosomes in each body cell. How many chromosomes would be found in its daughter cells after mitosis
Answer:
Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II. At the end of meiosis I there are two haploid cells.
Compare and contrast the skeletal body system with immune system
Abstract
In the last two decades, numerous researchers have focused on elucidating the relationship between the skeletal and immune systems with respect to their regulatory mechanisms. It has now become clear that osteoclasts are derived from the same myeloid precursor cells that can differentiate into macrophages and myeloid dendritic cells. In addition, bone and immune cells coexist in the common microenvironment of the bone marrow and are thus influenced by similar mediators. Discovery of a common regulatory mechanism via the receptor activator of nuclear factor kappa-B ligand (RANKL)–receptor activator of NF-κB (RANK)–osteoprotegerin (OPG) axis in both the bone and immune system has not only increased understanding of the fundamental processes of bone homeostasis but has further crystalized understanding of the definitive regulatory correlation between bone and immunity. Moreover, many of the soluble mediators produced by immune cells, including cytokines, chemokines, and growth factors, regulate the activities of osteoclasts and osteoblasts. This increased recognition of the complex interactions between the immune system and bone has led to the development of the interdisciplinary field of osteoimmunology. In this review, we summarize the characteristics of bone cells and the soluble mediators responsible for crosstalk between the skeletal and immune systems. A more complete appreciation of the interactions between immune and bone cells should lead to better therapeutic strategies for diseases that affect either or both systems.

Explanation:
Which coast of North America would you expect you to have a cooler overall climate
Answer:
east coast
Explanation:
During the winter, land is much colder than the oceans. When the westerly winds blow over it, the air cools substantially. By the time it reaches the East Coast, the moist air is cold enough to convert into snow. Thus, the East Coast experiences extreme cold weather during the winter.
Answer:
East Coast

What is the structure of cell membrane?The phospholipid bilayer, which forms a stable barrier between two aqueous compartments, is the membrane's fundamental structure. These compartments are the inside and outside of the cell in the case of the plasma membrane.
The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment.
The membrane of the cell is composed of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.
The heads (phosphate) are polar, whereas the tails (lipid) are non-polar. The heads, which form the outer as well as inner linings, seem to be "hydrophilic" (love water), whereas the tails, which face the cell membrane's interior, are "hydrophobic" (water fearing).
Thus, the correct option is B.
