Carol and Sam were using the microscope in science class. They used a dropper to put some pond water on their
microscope slide. This is what they saw. "That is something living," said Sam. "I don't think so," said Carol. What do you
think? Explain.
A)
This is not alive. It is not moving or responding.
B)
This sample is made of identical units. It is not alive.
This is a multicellular organism made of cells. It is living
D)
This may have been alive once but not now because it is not moving.
Answer:
Explanation:
I think Sam is right because pond water can be full of impurities which can include many microorganisms such fungi, bacteria, protozoa, etc. For example, there is high possibility that the pond water sample collected by Sam and Carol would contain traces of blue-green algae which is also a living organism as it uses sunlight to prepare its own food.

Every monarch butterfly migrates. This statement _______. A) is true B) can be made true by change "Every" to "No" C) can be made true by deleting "monarch" D) can be made true by changing "Every" to "The final generation
Answer:
The answer is option A "Is True"
Explanation:
The Monarch is notable for its capacity to travel significant stretches, and the migrations in North America are one of the best common marvels on the planet. This butterfly is additionally periodically recorded from the English Isles, making it our biggest and most extraordinary traveler butterfly.
Each fall, a great many ruler butterflies move 3,000 miles from their favorable places in northeastern North America to spend the colder time of year in the timber lands of southwestern Mexico. Every movement is by new generation, so they can't gain from others. All things being equal, they depend on their qualities. Their antennae have a genetic clock that reveals to them when to move and to explore they measure the sun's situation not too far off with their eyes.

Certain cells, such as those along the digestive tract, need to absorb a lot of materials. What unique functions do you notice about the shape of these cells? How might this improve their ability to absorb materials?
Answer:
Microvilli is very common in these cells. They increase the absorption area.
Explanation:
Epithelial cell surfaces show different structure shapes that allow the cells to adapt to and accomplish their functions. Most of these structures are related to the absorption surface and the need to move substances.
The development of microvilli is very common in epithelial cells. These are folds or finger-like projections emerging from the apical surface of the cell. Their principal function is to absorb. The microvilli of the intestinal epithelium are very uniform in size and distribution.

Scientists have discovered a new molecule found in the blood of wallabies. The molecule contains only carbon, hydrogen, and oxygen. After further examination, scientists discovered that the C, H, and O are in a 1:2:1 ratio. This molecule is most likely a ________.?
Answer:
carbohydrate
Explanation:
The molecule discovered by scientists in the illustration is most likely to be a carbohydrate.
Among all the biomolecules, only carbohydrates have the molecular formula of ([tex]CH_2O[/tex])[tex]_n[/tex]. On the other hand, carbohydrates generally contain carbon (C), hydrogen (H), and oxygen (O) in the ratio 1:2:1.
Since the molecule discovered by the scientists has C, H, and O in the ratio 1:2:1, then, it is, therefore, best thought of as a carbohydrate.

Which of The following are challenges to implementing sustainable farming practices? Select two correct answers.
a. increased need for fertilizer
b. lack of pollinating insects
c. higher initial costs
d. increased erosion
e. increase labor costs
Answer:
I think its A and E
Explanation:
^^^^^^
The challenges to implementing sustainable farming practices: higher initial costs; increase labor costs.
What is sustainable agriculture?It is an integrated system which includes both plant and animal farming practices, which hence has a minimum effect on the environment. It involves using substances of natural origin and hence meets the needs without causing an adverse impact on the environment.
What are its advantages?It prevents pollution since the waste remains in the farm's ecosystem.There is a reduction in the production of waste, and the waste of one is used in the other.It saves energy as there is a lower requirement for non-renewable resources.It doesn't use agrochemicals.It involves methods that reduce soil erosion, like managing irrigation, covering the soil with tillage.What are its disadvantages?It takes more effort since the use of machines is minimal.Limited use of land and hence, mass production is not possible.What are the challenges?New farmers have to struggle with high labor demand since it involves less use of machines and hence more workers are required.Before harvesting their first crop, young farmers require a huge sum of up-front capital, which is even more for biologically diverse farms.Hence the correct options are (c) and (e) higher initial costs; increase labor costs.
