Explanation:
If LAL (limulus amebocyte lysate) turns into a gel when exposed to a sample, it
means the sample is contaminated with gram-negative bacteria. True or false
Answers
Answer: The statement is TRUE.
Explanation:
Gram negative bacteria is a type of bacteria that possesses, from the interior to the exterior, a cytoplasmic membrane, a thin peptidoglycan layer, and an outer membrane containing lipopolysaccharide. The lipid portion of the lipopolysaccharide complex of the outer layer acts as an ENDOTOXIN.
The endotoxin of the gram negative bacteria can be detected in research or biomedical laboratories through a technique called LIMULUS AMEBOCYTE LYSATE test.
The test procedure follows a principle that the endotoxin of these gram negative bacteria are capable of forming gel clots (coagulation) of blood cell (amoebocytes) lysates of the Limulus polyphemus crab.
Therefore, If LAL (limulus amebocyte lysate) turns into a gel when exposed to a sample, it
means the sample is contaminated with endotoxins of gram-negative bacteria.
Luís is a rock collector. He thinks that the material from his favorite sedimentary rock in his collection might have been part of an igneous rock formation under Earth’s outer layer millions of years ago. Could Luís be correct?
a.
Yes, energy from Earth’s interior can cause igneous rock to break into small rock pieces that form sedimentary rock.
b.Yes, if igneous rock is moved to Earth’s surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock.
c.No, sedimentary rock can only form out of material from other sedimentary rock. There is no way that sedimentary rock can form from material in igneous rock.
d.No, sedimentary rock forms at Earth’s surface because energy from the sun causes rock to weather, but igneous rock under Earth’s outer layer is not exposed to energy from the sun.

The runoff from fertilizer has increased the phosphate levels in a nearby body of water. What effect does this increase in phosphate have on the body of water?
Increases oxygen levels
Colic
Fatigue
Increases algae growth
Answers
The effect that an increase in phosphate has on the body of water is increased oxygen levels. The correct option is A.
What are fertilizers?Fertilizers are compounds used to give plants the most nourishment possible for growth and development. They can also be administered directly to plants.
These chemical fertilizers include potassium as salt, phosphorus as phosphates, and nitrogen as nitrates. These chemical fertilizers pollute water bodies by entering through runoff when they are applied to soil or plants during rain.
Nitrates and phosphates enter water bodies as a result, leading to eutrophication. Algal overgrowth brought on by eutrophication results in low oxygen levels in bodies of water.
Therefore, the correct option is A. Increases oxygen levels.

Question: While the human immune system is generally effective at fighting bacterial infections, sometimes the infection overpowers the body’s defenses. In that case, the administration of an antibiotic may be necessary. How does an antibiotic work with the immune system?
A. The antibiotic works alongside the immune system without affecting it directly.
B. The antibiotic weakens the immune system, so the body doesn’t interfere with the actions of the drug.
C. The antibiotic strengthens the body’s nonspecific response, so the body is better able to keep out new types of bacteria.
D. The antibiotic strengthens the active immune response, so the body produces more antibodies to target the harmful bacteria.
Answers
Answer:
My guess would be option A.
Explanation:
Antibiotics work on bacterial infections. These chemicals kill the bacteria cells but do not affect cells that make up the body. For example, many antibiotics interrupt machinery inside bacterial cells that builds the cell wall.
What is one function of the organ system shown below in the picture?
Answers
The circulatory and respiratory systems are involved in respiration. They provide oxygen to the body cells and remove carbon dioxyde. The correct option is A. To remove carbon dioxyde from the body.
Two systems work together when providing oxygen to the body cells and removing carbon dioxide: The circulatory and respiratory systems
• Respiratory systemThis system is in charge of the gasses interchange. It takes oxygen from the air and releases carbon dioxide.
• Circulatory systemThis system is in charge of driving oxygen to the organism's tissues and cells and taking away carbon dioxide from them.
These gases are in the oxygenated and deoxygenated blood, respectively.
The heart bombs blood through arteries, veins, and capillaries to the whole body.
The blood carries oxygen to different tissues.
This oxygen is absorbed in the lungs and proceeds from the air that we breathe. Its final destiny is all the cells in the organisms.
Types of circulation• Lung circulation
1. Moves blood between the heart and the lungs.
2. Deoxygenated blood goes from the heart to the lungs
3. In the lungs, deoxygenated blood releases carbon dioxide and gets oxygenated again.
4. Carbon dioxide is released by exhalation.
5. Blood absorbs oxygen from small air sacs named alveoli.
6. Oxygenated blood returns to the heart.
• Systemic circulation
1. Carries blood between the heart and the rest of the body.
2. Oxygenated blood leaves the heart and moves to all the cells in the body.
3. Deoxygenated blood returns from tissues to the heart.
According to thi framework, the function of the organ system shown in the picture is to remove carbon dioxyde from the body. Option A.

Answers
Answer:
gigantism
Explanation:
The growth hormone is responsible for stimulating normal growth in humans or in other words, stimulating growth at a normal pace. To do this, the growth hormone must be released in optimal quantities, however, an hypersecretion i.e. excessive release of the hormone will cause a fast and uncontrollable growth in certain regions of their body or the whole.
This abnormal excessive growth caused by an excessive release of the growth hormone is called GIGANTISM. Gigantism occurs mostly in children at their growing phase.

An air mass acquires the temperature and humidity of its source region.
True
False
Answers
An air mass acquires the temperature and humidity of its source region is a true statement, an air mass is a substantial volume of air that contains both temperature and humidity.
What is an air mass?As the name implies, an air mass is a substantial volume of air that contains both temperature and moisture. The temperature will change depending on where the air mass is located, for instance, the temperature will always be lower in the center of the air mass.
Similar to how air mass humidity fluctuates, air mass humidity will not change when air temperature decreases.
However, depending on the environment, it may either gain or lose water mass. Temperature and humidity may change at any time, but the pressure never does.
Therefore, air mass acquires the temperature and humidity of its source region is a true statement.
