Macrophages are cells from the immune system that recognize and eliminate strange elements. Option A. Inflammatory responses typically include increased activity of phagocytes in an inflamed area.
What is macrophages function?
Macrophages are one type of white globules involved in the organism's defense against strange substances and pathogen agents. They are the principal actors in the immune response.
Macrophages recognize different strange molecules that penetrate the organism (bacterias, parasites, and viruses), phagocyte and eliminate them. This process known as phagocytosis.
When macrophages are activated, they release cytokines that favor inflammation response, neutralizing the pathogen agent and removing damaged tissue from the affected area.
Together with inflammation, there is a change in blood flow, increasing the permeability of blood vessels, and enhacing the migration of fluid, proteins, and other immune cells to the affected area.
The correct option is A. Inflammatory responses typically include the increased activity of phagocytes in an inflamed area.

List the three processes involved in the formation of urine in order. 1. tubular secretion 2. tubular reabsorption 3. glomerular filtration
In this question, We list the three processes involved in the formation of urine in order. 1. glomerular filtration 2. tubular reabsorption 3. tubular secretion
Steps of urine production
Inside the renal capsule, the blood undergoes strong pressure, which causes the output of the so-called glomerular filtrate (or initial urine), a liquid similar in composition to blood plasma. This process is called filtration. The filtrate is mainly made up of water, urea, glucose, salts and amino acids. It is important to remember that blood cells and some larger proteins do not pass into the capsule.
After leaving the renal capsule, the filtrate passes through the length of the nephric tubule and water and useful substances are reabsorbed into the body. These substances go back into the bloodstream. Most of the reabsorption occurs in the proximal tubule region.
In the tubules, the process of secretion also takes place, in which some metabolites and drugs are carried from the blood vessels into the tube.
After passing through the entire nephric tubule, we have the filtrate transformed into urine.
With the information obtained, we list the three processes involved in the formation of urine in order. 1. glomerular filtration 2. tubular reabsorption 3. tubular secretion

Which process is shown in the image?
A. Passive transport
B. Endocytosis
C. Exocytosis
D. Active Transport
Answer:
Explanation:
Endocytosis
The process shown in the image is of Endocytosis. It is a type of cellular transport through which different substances enters the cell. Thus, the correct option is B.
What is Endocytosis?
Endocytosis is a process during which substances are brought inside the cell. The materials which are to be internalized are first surrounded by the plasma membrane. The plasma membrane in-folds across the substances to form a vesicle.
The vesicle formed by the in-folding of the plasma membrane then fuses with the membrane and buds off into the cell. Thus, the substance are delivered inside the cell.
Endocytosis is of two types- pinocytosis (cell drinking) and phagocytosis (cell eating). Examples of endocytosis includes uptake of cholesterol-bound low density lipoproteins, and recycling of iron-bound transferrin, etc.
Therefore, the correct option is B.

An omnivore eats both like people so since omnivores also eat meat, it's not that either. And lastly, A decomposer breaks down organic material such as mushrooms. Therefore, a cow is a herbivore.
A liquid thermometer and an electronic thermometer are both properly placed in the same liquid. The liquid thermometer shows 53.4 degrees Celsius and the electronic thermometer shows 58.2 degrees Celsius. Which could best explain why they show different readings?
Answer:
The correct answer would be - electronic thermometer was not calibrated correctly
Explanation:
Every electronic equipment or instrument like an electronic thermometer, that measures something needs to be calibrated with a standard measurement or reference value to a new measuring device to establish a relationship.
Liquid thermometer measures based on the liquid's actual physical properties, that are present inside it so, calibration is not required.
Thus, the electronic thermometer was not calibrated correctly.

supposed the primary producers in the energy pyramid shown contain 76500 kj of energy. how much would be available for the organisms on the tertiary level ?
Answer:
76.5Kj
Explanation:
A food chain consists of different trophic levels of organisms ranging from the PRODUCERS to the TERTIARY CONSUMERS. According to the pyramid of energy, only about 10% of energy is available for use for the next trophic level as majority of the energy (about 90%) is lost as heat.
Hence, if the primary producers in the energy pyramid contains 76500kJ of energy, the following energy would be available for each trophic level.
Primary producers: 76500kJ
- 10% of energy will be available to the primary consumer = 10/100 × 76500 = 7650kJ
- 10% of energy (7650kJ) will be available to the secondary consumer = 10/100 × 7650 = 765kJ
- 10% of energy (765kJ) will be available to the tertiary consumer = 10/100 × 765 = 76.5kJ
Hence, 76.5kJ of energy will be available for organisms at the tertiary level.

Which of these describes one way that the human nervous system maintains a constant body temperature when the external temperature is cold?
A. The Nervous system increases perspiration
B. The nervous system causes digestion to speed up
C. The nervous system causes bloods vessels to construct
D.The nervous system triggers the flight-or-flight response
Answer:
A
Explanation:
Nerves trigger sweat glands to release fluid that evaporates and cools the skin. Conversely, a drop in core temperature makes blood vessels constrict to conserve heat. The nervous system also triggers muscles to shiver to generate heat and warm the body.Apr 15, 2018
The nervous system causes blood vessels to constrict. Therefore, option (C) is correct.
What is nervous system?When the external temperature is cold, the human nervous system works to maintain a constant body temperature through a process called thermoregulation. One way this is achieved is by causing blood vessels near the skin to constrict, reducing blood flow to the skin and helping to retain heat within the body's core. This response is known as vasoconstriction.
Vasoconstriction is controlled by the sympathetic nervous system, which is part of the autonomic nervous system. This system is responsible for controlling involuntary bodily functions, including heart rate, blood pressure, and body temperature. When the body's core temperature drops, the sympathetic nervous system activates and causes the blood vessels to constrict, helping to maintain a constant internal temperature.
Increasing perspiration (A) can help to cool the body down in hot conditions, but it is not a mechanism for maintaining body temperature in cold conditions. Digestion speeding up (B) and the flight-or-flight response (D) are not directly related to temperature regulation.
