Acontiguous stretch of DNA formed from overlapping DNA fragments is known as a contig. Contigs are a crucial component in DNA sequencing and genome assembly.
A set of overlapping DNA fragments that form a contiguous stretch of DNA is referred to as a contig. In molecular biology and genetics, contigs are used in the process of DNA sequencing to assemble larger sequences of DNA from smaller sequences or fragments. Creating a contig is a crucial step in genome assembly, and it is typically accomplished using computer algorithms that match overlapping ends of different DNA fragments.

b. A text book discussing the causes of WWII
c. A photo featuring a farmer collecting his crop
d. A television interview with a person who survived Hurricane Katrina
Answer: Option B
Explanation:
A historical research project, secondary sources can be defined generally as scholarly books and articles.
This sources first analyses and interprets the primary sources. These sources contains pictures, graphics and quotes.
A secondary source is usually used to describe an event or incident with the help of picture, quotes and graphics.
hence, the correct answer is option B
Lipids help the animal conserve heat.
-natural event such as an earthquake
-Migration of organisms to a new population
Answer:
An error in DNA replication
Explanation:
Breathing trouble
Cancer
Respiratory infection
Answer:
The correct answer is option , Breathing trouble
Explanation:
Opioids are narcotics that are prescribed by doctor during surgeries but addiction to its continued usage may result into weakening heart beats and slow breathing. The breathing issue arises when specific opioid receptor in the central nervous system (CNS) gets activated thereby affecting the respiratory rhythm. The respiratory rhythm in the CNS is controlled by pre-Bötzinger complex. Opiods also affects the functioning of lungs by slowing down its expansion and contraction mechanism .
I believe the correct answer is breathing trouble
Opioids are a group of molecules that produce an analgesic effect during pain and can be misused as drugs for a "good feeling." Just like any other drugs, they have to bind to receptors in order to produce an effect by entering into a cell and causing a chemical reaction. The specific receptors are called mu receptors in the brain.
The mu receptors are located in the brain and they line up to the hind part of the brain where there are sites called pons that function to control the autonomous nervous system that is responsible for involuntary activities like breathing and heartbeat. A good example of an opioid that is used for medicinal purposes is morphine that binds to its receptors to prevent the brain from recognizing pain. In the pons that control the autonomous nervous system, there is a complex called pre-Bötzinger complex that has the μ receptors for the opioids extensively. When a person takes the opioids, they attach to their receptors in order to produce an effect by acting as antagonists (opposing) to the pain molecules in blood. In so doing, they also antagonize the nerve cells that are found in the pre-Bötzinger complex. The end result is a suppressed autonomous nervous system. The lungs will have a problem expanding and relaxing, the heart rhythm will be irregular and the person if not given assistive care, may lose consciousness due to lack of oxygen supply to the brain. Cancer is a condition that is caused by alterations to the genetic material in an organisms causing cells to replicate uncontrollably. Respiratory infections are conditions where microorganisms enter into the tract and impair their functioning for example Streptococcus pyogenes bacteria entering your throat causing the condition called sore throat.

A.) Both are involved in providing energy to the cells.
B.) These materials can be cycled through the body.
C.) The body will be able to absorb materials it needs from the environment.
D.) Waste can be removed from the cells of the body.
Answer:
i think its D
Explanation:
Because homeostasis is to maintain the internal enviroment of an organsism body constant .
organs responsible for homeostasis :
lungs: keep the concentration of carbondioxide and oxygen constant
skin: regulates the body temperature
kidney: regulates the concentration of water and urea
liver : regulates blood sugar level
To maintain the same concentrations inside the cells as outside of them, the blood's water and mineral ion levels are regulated. By preventing too much water from entering or exiting the cells through osmosis. Thus, option D is correct.
Your body makes use of hormones like glucagon and insulin to maintain homeostasis. Insulin is released to counteract this alteration if your blood glucose level is too high.
Insulin helps your body cells absorb extra sugar from your blood. Glucagon reacts immediately if your blood glucose level is low.
The neural and endocrine systems maintain homeostasis. A response to a stimulus known as negative feedback keeps a variable near to a predetermined value.
Therefore, Waste can be removed from the cells of the body by homeostasis.
