Which of the following describes a scientific law?
A. People have the right to a speedy trial.
B. Any two objects in the universe attract each other with a force called gravity.
C. The universe may have begun from an explosion (or big bang) from a single point.
D. Students must wear their safety goggles in the lab.
Answer:
B. Any two objects in the universe attract each other with a force called gravity.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
Hence, the statement which best describes a scientific law is, any two objects in the universe attract each other with a force called gravity.
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.

Lakesha was culturing bacteria. She used aseptic technique to make sure there was no contamination. When she was finished, she used water to clean the surface of her table. She then put the sample in the incubator, removed her gloves, and washed her hands with soap and water.
Answer:
d. She should be using a disinfectant on her table, not just water.
Explanation:
When Lakesha finished culturing the bacteria, she should not have used water alone to clean the table because water can't kill bacteria. She has to use a disinfectant in order to remove bacteria from the table. This disinfectant has the ability to kill all the bacteria that is present at the table and there is no chance of infection from these bacteria. So we can say that she made a mistake to clean the table with just water and not using the disinfectant over it.

There are more than 300,000 species of plants that have been identified thus far in the world today; many new species are being discovered each year. In addition to providing most of the oxygen for land animals, plants do many other things for us. you will research the Internet and use reliable and credible scientific websites to investigate a specific plant species and choose a way (other than providing oxygen) that plants are useful to humans. [NOTE: Hot topic plants like Marijuana and Opium are off limits and cannot be discussed.]
Writing a full paragraph (a 150-words minimum) for your initial blog post discussing a specific species of plant and the benefit you chose. Be sure to describe what type of plant it is. Where is it found? How does it impact humans or other species? What role does it play in the ecosystem, etc.?
Answer and Explanation:
We can mention the advantages of the plants of the Fabaceae family, also known as legumes, such as beans, soybeans, peanuts and peas. First, we must mention how these plants have high nutritional values providing high levels of iron and nitrogen that are essential elements for human health. However, a benefit that these planats produce and that is important on a worldwide scale is the fixation of nitrogen in the soil. All living beings need nitrogen in their bodies, since nitrogen is a primary element in the composition of nucleic acids and proteins. Animals are able to ingest nitrogen from the vegetable diet, but vegetables cannot absorb nitrogen from the atmosphere or nitrogen from the soil, because they are not in molecular forms that plants can absorb. To reverse this, farmers put chemical fertilizers on the plantations, but these fertilizers pollute the environment intensely. It is in this scenario that the plants of the Fabaceae family are important. This is because these plants are able to associate with bacteria that can capture atmospheric nitrogen and place it in the soil, in the molecular form that all plants can absorb. This allows plants to have the necessary nutrients for their growth, reduces environmental pollution, decreases spending on agricultural production, promotes correct levels of nitrogen for human consumption and allows agricultural products to be healthier.

Years after the lava from an erupting volcano destroyed an area, lichens started to grow in that area. These were gradually replaced by grasses, shrubs, conifers, and finally by a deciduous forest. In this sequence of events, the lichens functioned as What?
(Answer if you know.)
A. primary consumers
B. abiotic factors
C. pioneer organisms
D. climax organisms
Answer:
I'm pretty sure it's c
Explanation:
I'm 80% sure its c I learned this last month
In this sequence of events (ecological succession), the lichens functioned as a class of pioneer organisms (Option C).
What is ecological succession?Ecological succession refers to the progressive emergence of different organisms and/or species in an ecosystem.
The ecological succession occurs after a period of ecological disturbance in the ecosystem.The ecological succession is fundamental for recovering the homeostasis of the ecosystem.In conclusion, in this sequence of events (ecological succession), the lichens functioned as a class of pioneer organisms.

Explain how prokaryotes (note that this is for prokaryotes and NOT eukaryotes) control gene expression.
Answer:
By Controlling transcription
Explanation:
Prokaryotic cells regulate their gene expression by controlling the amount of transcription. This is the only way of regulating the gene expression.
Unlike the prokaryotic cell, in eukaryotic cell, different compartments were formed for carrying out different cellular processes. Later on, transcription and translation were physically separated and were carried out in two different cellular compartments

An acid-fast staining method was performed on a bacterial smear using the dyes carbol fuchsin and methylene blue. The resulting stained slide contained only cells that appeared blue when visualized using a microscope. Which of the following could explain why only blue cells were present?
a. No acid-fast bacteria are present on the slide
b. Methylene blue was not used
c. Carbolfuchsin was not used
d. Acid-alcohol was not used
Answer: Only blue cells where present because No acid-fast bacteria are present on the slide. The correct option is A.
Explanation:
Acid fast staining method also called Ziehl-Neelsen (Zn) technique is used in the laboratory to stain samples suspected to contain Mycobacterium species. The Mycobacterium species which includes the M. tuberculosis, M. ulcerans, and M. leprae, do not stain well by the Gram technique, which is a common routine stain in the laboratory. This is because of waxy coating on its cell surface primarily due to the presence of mycolic acid.
The acid fast stain consists of:
--> A primary dye which is the carbol
fuchsin
--> A decolorizer which is the acid alcohol
--> A counter stain which is the methylene blue.
In it mechanism of action on the bacterial smear, when the primary dye is applied,the whole cell will appear red. But after decolorizing with acid alcohol, only acid fast bacteria will retain the red colour of carbol
fuchsin while the red dye from the background cells are removed. Then the counterstain (methylene blue) is applied which is picked up by non-acid-fast bacteria making the cells appear blue under the microscope.
Therefore when the bacteria smear is viewed under the microscope and only blue cells are seen, it means No acid-fast bacteria are present on the slide.
Are Parakeets good starter pets? why or why not
Answer:
NO! They require a ton of attention, a large cage, and experience with birds. Parakeets are often marked as starter pets, but no, they are not.
First, they need a 3 feet long cage with 5+ toys that need to be changed each month. And they need natural perches, not the cheap wooden dowels, they will get feet problems. Most people don't do this, having a bored pet.
Second, parakeets will chew anything given/available to them, and a lot of things can be toxic to them, which can lead to the death of your pet.
Third, parakeets are messy and noisy. They poop a LOT and love to toss seeds around their cage. They also need millet and a calcium chew, which are also messy.
They also will want a friend, they are flock animals in the wild so 3-4 birds is a good number, but getting more birds means getting a large cage. The pet store will tell you it's fine, but it is not. ALWAYS SEEK HELP FROM A BIRD BREEDER.
Lastly, they need a bird proofed room to fly around in. No matter how large your cage is, they still need some out-of cage time.
Try a dove or pigeon instead, they are listen the #1 easiest and cheapest to care for pet bird.
