burning temperatures, such as those of a hot stovetop, are perceived by which component of a reflex arc? (2 points) effectors receptor dorsal root ventral root

Answers

Answer 1

Burning temperatures, such as those of a hot stovetop, are perceived by receptor component of a reflex arc. This is the option B

What is the reflex arc?

It is common to see that when there is sudden pain or we touch something that is hot, we would instantly withdraw our hands from the source of the heat. Why do we do that? The reason why we feel heat is because of the nervous system.

The nervous system is composed of electrical receptors that can be found all around the body. These receptors are able pass on electrical signals from any part of the body to the brain and they help in the coordination of the affairs of the human body.

The way that the nervous system works is called the reflex arc of the system. It passes the information that it picks up directly to the brain for prompt action.

The opposite strand of DNA that will be created from the above original strand is as follows: 3'- T A G G G C T T A C G T A A G -5'

What is DNA replication?

DNA replication in biology refers to the process of producing two identical replicas of DNA from one original DNA molecule.

The replication process relies on the fact that each strand of DNA can serve as a template for duplication.

In a double stranded DNA molecule, the base A (adenine) pairs with base T (thymine) while G (guanine) pairs with C (cytosine).

This means that based on the above DNA strand, the opposite strand that will be produced after DNA replication is as follows: 3'- T A G G G C T T A C G T A A G -5'.

The principal difference between tropical and temperate rainforests is the amount of precipitation they receive.
true
false

Answers

The principal difference between tropical and temperate rainforests is the amount of precipitation they receive. The statement is false.

Rainforests are classified into two types: tropical and temperate. Tropical rainforests are situated closer to the equator, when temperatures are higher. Temperate rainforests can be found near colder coastal locations north or south of the equator.

The tropical rainforest is a hot, damp ecosystem with year-round rain. It is famous for its lush plant canopies that form three distinct levels. The highest layer, or canopy, comprises gigantic trees that may reach heights of 75 meters (approximately 250 feet).

A vast variety of plants from this level are commonly used as houseplants. These plants adapt quickly to residential surroundings due to the limited quantity of sunshine and rainfall they receive. Wet leaves and leaf litter cover the rainforest's lowest layer or floor.

Due to a lack of sunshine, there are few vegetation on the forest floor. However, the hot, wet environment and all of the dead plant debris offer ideal circumstances for bacteria and other microbes to thrive.

If you do a really tough workout, you may begin to breathe hard and think that you have run out of energy. You will sometimes experience a burning sensation in your muscles. What are you really running out of when you think that you are running out of energy? Explain the process that your body is going through when you experience the “burn”.

Answers

The burning sensation during heavy exercise is due to the formation of lactic acid in muscles

Importance of heavy workout:

Although a rigorous workout is believed to be good for the body, why do muscles hurt so much afterwards? After a vigorous workout, the burning in the muscles can last for up to 72 hours. As the body adapts to the new physical demands placed on it, it grows muscle as part of the process. For muscles to be sufficiently challenged to promote growth, the body needs to be stimulated with a certain level of difficulty. The burning you experience is a necessary component of muscle development.

Heavy exercise good or bad?

When you are tuned in, you will be able to sense when something is off with your body since it has innate wisdom. Although exercise might become intense, it should never be painful. Even though you will likely feel worn out and sore after working out, you will still be able to move about without agonizing discomfort.In contrast, your range of motion and capacity to carry out typical daily tasks will be significantly altered when the body experiences pain following an injury. This suggests that there might be a problem. When this happens, it is advisable to see a specialist who can fully evaluate you. Fractures can be found using X-rays, while soft tissue injuries can be found using ultrasound or MRI examinations.

Hence this burning sensation is due to the formation of byproduct of anaerobic respiration i.e., lactic acid.

The process that is directly responsible for the transmembrane movement of K⁺ and Mg²⁺ in the animal cell is the active transport (option)

Explanation:

The transport of ions through the membrane occurs through an active transport process, since they are charged particles.  Potassium (K⁺) and Magnesium (Mg²⁺) are ions, and their movement through the membrane occurs by active transport

The cell membrane is predominantly hydrophobic, limiting the free passage of polar molecules and ions. The transport of ions occurs through membrane ion channels, where the ions move following an electrochemical gradient, or through active transport mechanisms that require energy. One of the best known active transport mechanisms is the Na⁺-K⁺ ATPase pump.

The other options are not valid because:

Circulation: refers to the movement of objects or substances through a channel. Diffusion: in the case of cell membranes is the passage of substances through them in a passive way, without the use of energy. Electrophoresis: is a technique used to separate molecules according to the way they move in an electric field.

the class of bacteria that will show a defined clear zone around colonies on blood agar are

Answers

The class of bacteria that show a defined clear zone around colonies on blood agar are known as hemolytic bacteria.

These bacteria produce enzymes called hemolysins, which are responsible for breaking down red blood cells and causing the clear zone, or hemolysis, to appear around the bacterial colonies on blood agar plates.

There are two main types of hemolysis observed in hemolytic bacteria: alpha (α) and beta (β) hemolysis. Alpha-hemolytic bacteria, such as Streptococcus pneumoniae, cause partial destruction of red blood cells, resulting in a greenish discoloration surrounding the colonies. Beta-hemolytic bacteria, like Streptococcus pyogenes, completely break down red blood cells, creating a defined clear zone around the colonies.

Blood agar is a valuable tool in microbiology, as it allows for the differentiation of bacteria based on their hemolytic properties. This can help in identifying the specific type of bacteria responsible for a given infection, which is essential for selecting the appropriate treatment and improving patient outcomes.

a. acquiring random mutations
b. responding to environmental changes
c. maintaining a healthy social structure
d. remaining genetically stable.

Answers

The capacity of the southern right whale species that is most severely diminished by the bottleneck is the ability to remain genetically stable and maintain a diverse gene pool.

A genetic bottleneck is a reduction in the size of a population that leads to a loss of genetic diversity. This can occur due to a number of factors, including natural disasters, disease outbreaks, or human activities such as hunting or habitat destruction. In the case of the southern right whales, the population was severely reduced by whaling activity in the 19th and early 20th centuries, leading to a genetic bottleneck. The capacity of the species that is most severely diminished by the bottleneck is the ability to maintain a diverse gene pool, which is necessary for the species to adapt to changing environmental conditions and respond to new challenges. When a population experiences a genetic bottleneck, the number of different genes available for selection is reduced, leading to a loss of genetic diversity. This can make it more difficult for the population to adapt to new challenges and can increase the risk of extinction.

Marcus consumes about 100 grams of protein each day. Of this, 25 grams is broken down and used to make ATP, and 25 grams is used to synthesize (make) body fat. What does this tell you about Marcus's protein and calorie intake?​

Answers

This is because he consumes 100 grams of protein each day, and it is not mentioned that he consumes any additional protein beyond this amount.

What is ATP?

ATP stands for adenosine triphosphate, which is a molecule that is commonly referred to as the "energy currency" of the body. ATP provides the energy that is required for most cellular processes, including muscle contraction, nerve impulse transmission, and protein synthesis.

The structure of ATP consists of three phosphate groups attached to an adenosine molecule. When ATP is used to provide energy for cellular processes, one of the phosphate groups is broken off, releasing energy in the process. This results in the formation of ADP (adenosine diphosphate), which can be converted back into ATP through the addition of a phosphate group.

We also know that 25 grams of the protein he consumes is used to make ATP, which is the primary energy source used by the body. This means that Marcus's body requires a significant amount of energy each day, and that he is likely consuming enough calories to support this energy demand.

Finally, we know that 25 grams of the protein he consumes is used to synthesize body fat. This suggests that Marcus may be consuming more calories than he needs, as excess calories are typically stored in the body as fat.

Explanation:

Explanation:

If you take antibiotics for the wrong reason(s) or if you take them too often it can change bacteria so much, that antibiotics have a reduced effectiveness against them, or stop working against them all together.

The so called "bacterial resistance" or "antibiotic resistance" is a real thread to humans. Some bacteria have turned out to be resistant to even the most powerful antibiotics available. Antibiotic resistance is a growing problem.

Suppose you get infected with such resident bacteria, it means there is no longer an effective treatment by using antibiotics.

*EXTRA*

If left "un treated", the bacteria can grow, more or less, with unlimited exponential growth. In such scenarios, any "simple" bacterial infection, could turn out to be fatal.

Often the biggest problem is the lack of time to find out exactly what type of bacteria is making the patient ill. Because there are so many different bacteria, it is impossible to tell what is the right one without deduction and, that takes time (to grow visible cultures in the laboratory). Sometimes a patient might be already critically ill, in such cases, the doctor would want to start the treatment immediately, which could mean they HAVE TO start admitting a broad-spectrum antibiotic, to hopefully battle that group of different bacteria, which hopefully included the one that is making the patient ill. But if that specific bacteria turns out to be resestant, then that poses a very serious problem. Possible a fatal one, since the time is up, and the bacteria keep growing in numbers, roughly doubling in numbers every hour...
