Answer : A
Explanation:
Inventing tools can help humans survive in their environment. Therefore, option (A) is correct.
Why inventing tools help human survive?Culture refers to the shared beliefs, values, practices, and knowledge that characterize a group or society. Humans have relied on culture to survive and thrive for thousands of years. Inventing tools is an example of how culture can help humans survive. By creating and using tools, humans are able to adapt to and manipulate their environment to meet their needs. For example, early humans used tools to hunt, gather food, and build shelters, which helped them survive in their environment.
Overusing resources can lead to unsustainability and environmental degradation, which can threaten human survival. Developing different religions can lead to conflict among societies and does not necessarily help humans survive. Having opposable thumbs is a physical adaptation that has helped humans develop complex motor skills, but it is not an example of how culture helps humans survive.

What is one function of the organ system shown below in the picture?
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.

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
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.

What is the main way the flu virus spreads through a population?
A. Infected people
B. Plant toxins
C.Alcohol use
D.Mosquitoes
Answer: The answer is A. Infected people
Explanation:
People with flu can spread it to others up to about 6 feet away. Most experts think that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Less often, a person might get flu by touching a surface or object that has flu virus on it and then touching their own mouth, nose, or possibly their eyes.
