Which defensive adaptation would best help a plant survive in an environment with leaf-eating animals?
A.
large fruits
B.
thick stems
C.
sharp thorns
D. colorful flowers
Answer:
C. sharp thorns
Explanation:
The plants stand still, are not very physically active, and seem to be on the menu of many animals. Precisely because they cannot win at the first sign of danger, one has developed other ways in which they can defend themselves from annoying and dangerous animals.
Some have developed long thorns that repel attackers. Some have poisons that are very strong and because of which animals do not think of trying to eat that plant, but the defense of some plants seems to be well thought out and ready for all forms of attack.

Elevated fibrinogen levels result in a(n) ___________, which increases the risk of a coronary or cerbrovascular incident.
Answer:
hypercoagulable state
Explanation:
Elevated fibrinogen levels result in hypercoagulable state , which increases the risk of a coronary or cerbrovascular incident.
A hypercoagulable state in medicine refers to a condition in which there is an abnormal increase in the tendency toward the clotting of blood also known as blood coagulation.
When fibrinogen levels are high, there is an increase in clot stiffness, increase in resistance of the clot to fibrinolysis as well as an increased blood viscosity.
1. Chantelle was given a sample of breakfast cereal to test for carbohydrates. (a) First, she decided to test the sample for glucose. Describe the test she should carry out and the results she might expect if glucose is present.
Answer:
The correct answer is - Benedict's solution for the test for glucose in food.
Explanation:
Benedict's solution is a test that is used to check if there is a presence of glucose in a food sample or not. It is possible due to the oxidation of the aldehyde present in the glucose turns to carboxylic acid in presence of the clear blue solution of sodium and copper salts or benedict's solution.
In presence of Benedict's solution the color of the sample turns yellow to orange with an increase in heat, however, the initial color of the solution is aqua blue.
Thus, the correct answer is - Benedict's solution for the test for glucose in food.

In what stage are humans learning essential skills like hunting, cooking and animal identification
Adult
Childhood
Adolescence
Infancy
Answer:
Adolescence
Explanation:
Given that infancy, age is the age of little children from the point of birth to about four years
Hence, this cannot be an answer.
Childhood is wrong because the childhood age is the age of 2 to 13. At such a tender age, one cannot go hunting due to fear of wild animals or have the capacity to learn to cook different food
Adult is also not correct because Adult age lies between 21 to 40 when middle age comes by. At this stage, one is expected to have at least basic skills to survive.
Therefore the correct answer is Adolescence. This is the age of 10 to 19. It is the last stage before Adulthood where one has to hone his basic and surviving skills. At this point, it is believed one has full mental capacity.

Why are cells so small?
Answer:
Why are cells small? because they can absorb nutrients much more efficiently. Because they are smaller they can efficiently absorb enough food. When a cell doubles in size the volume increases much more then the surface area, which is why large cells cannot receive enough food efficiently for their volume.

Question 2
In this part of the experiment, you’ll prepare and test three milk solutions: milk and water, milk and lactase enzyme, and milk and heated lactase enzyme.
Prepare
Use masking tape to label the three beakers: “milk,” “lactase solution,” and “heated lactase solution.”
Measure 60 milliliters of milk in the graduated cylinder (or ¼ cup of in a measuring cup. Pour it into the beaker labeled “milk.”
In the beaker labeled “lactase solution,” add one lactase tablet and 100 milliliters (or 1/2 cup) of cool or room-temperature water. Use the stirrer to dissolve the lactase tablet in the water.
Add 100 milliliters (or 1/2 cup) of milk to the microwaveable container. Dissolve a lactase pill in the container. Put the solution in the microwave and heat it to boiling (about 2 minutes). Use oven mitts to remove the container. Pour the heated lactase solution into the beaker labeled “heated lactase solution” and let it cool.
Stay safe! Be careful while handling the boiled mixture to avoid spilling it on your hands.
Test
While you’re waiting for the lactase solution to cool, read the directions on the test strips. The test strips in the Edmentum lab kit will react to glucose within a few seconds. If you use different strips, the reaction time may vary. Now follow these steps to test the solutions. Record your data in the answer space.
Milk and water solution: Fill the first test tube one fourth full of milk. Fill the small graduated cylinder with water and gently add it to the milk in the test tube until the test tube is half full. Use the stirrer to thoroughly mix the solution. Then insert the test strip for 10 to 20 seconds. Look at the test strip, and record whether it changed color. Wash the stirrer.
Milk and lactase enzyme solution: Fill the second test tube one fourth with milk and one fourth with the lactase solution. Use the stirrer to thoroughly mix the solution. Insert the test strip for 10 to 20 seconds, and record whether it changed color. Wash the stirrer.
Milk and heated lactase enzyme solution: Fill the third test tube with one fourth milk and one fourth of the heated lactase solution. Use the stirrer to mix the solution. Insert the test strip for 10 to 20 seconds, and record whether it changed color.
Note: Keep the lactase and heated lactase solutions for the next part of the experiment.
Wash the “milk” beaker, the test tubes, and the stirrer. If you used paper cups as an alternative, throw them away.
Answer:
The bacterium should stop production of lactase.
Explanation:
This is because the E. coli bacteria can degrade lactose, but lactose is not preferred as source of fuel or energy to glucose. If glucose is present, E. coli would preferably employ it over lactose as Glucose needs little process and minimal energy to degrade when compared to lactose. Although, if lactose is the major sugar that is present, the E. coli will have no option than to employ it as it's source of fuel or energy. The formation of lactase enzyme utilizes energy, which cannot be utilised in the presence of high level glucose.
This appears to be a set of instructions for a lab experiment involving testing different milk solutions with lactase enzyme.
What is lactase enzyme?Lactase is an enzyme that breaks down lactose, a sugar found in milk and dairy products, into glucose and galactose. People who are lactose intolerant have insufficient levels of lactase, which can lead to symptoms such as bloating, gas, and diarrhea when they consume dairy products.
The experiment involves preparing three different solutions (milk and water, milk and lactase enzyme, and milk and heated lactase enzyme) and then testing each solution with a test strip to see if it changes color, indicating the presence of glucose.
The instructions also include safety precautions, such as being careful while handling the heated lactase solution. Finally, the instructions remind the reader to wash all equipment used in the experiment.
Some people may have lactose intolerance, which means that they do not produce enough lactase to break down lactose in their bodies, resulting in discomfort and digestive problems.

2. A unique characteristic of the banyan tree is that roots grow down from its
branches into the ground. The tree can appear to have several trunks. What
advantage does this root characteristic give the banyan tree over other trees?
A. The roots provide shelter for ground-dwelling animals, which carry nutrients
to the tree.
B. The banyan can grow near the equator, because aboveground roots are
more protected from the sun.
C. The banyan can only grow in humid climates, because aboveground roots
are more likely to dry out and die during droughts.
D. The banyan can grow in areas prone to hurricanes and typhoons because
the roots make the tree more stable in high winds.
Answer:
D. The banyan can grow in areas prone to hurricanes and typhoons because
the roots make the tree more stable in high winds.
Explanation:
According to this question, banyan tree posseses a unique characteristic in which roots grow down from its branches into the ground making the tree appear to have several trunks. This type of root is called STILT OR PROP roots.
The major function of this stilt roots is to provide additional support for the plant during adverse conditions. Hence, a major advantage that this root characteristic give the banyan tree over other trees is that it confers resilience upon the banyan tree, making it able to grow in areas prone to hurricanes and typhoons because the roots make the tree more stable in high winds.
Drop a paper, a piece of thermopol, and a piece of plastic from a height of 10-15 feet. Note the time for each object to hit the ground. Why does the paper take more time than thermopol and thermopol more than the plastic piece? Make the paper to fell down in such a way that it should hit the ground before all of them. How did it happen? Explain.
It took the paper longer as it has quite a few surface places that air can withstand and push up, making it glide slowly to the ground rather than drop fast. The piece of plastic is likewise extra aerodynamic than the piece of paper because the air won't have as an awful lot of floor regions to face up to.
What is aerodynamic in simple terms?Aerodynamics is the way air actions around matters. The guidelines of aerodynamics give an explanation for how an aircraft is capable of fly. whatever that movements through air reacts to aerodynamics. A rocket blasting off the launch pad and a kite within the sky react to aerodynamics. Aerodynamics even acts on vehicles, considering that air flows around motors.
What is an aerodynamic example?Aerodynamics is the way air moves around matters. given that air is all around us, there are many examples of aerodynamic technology other than for aircraft. take a look at golf balls for instance. golfing balls have their unique shape with loads of dimples on them to improve their aerodynamics and create more lift.
