What is system in nature?Systems encountered in nature at Earth's surface, such as a forest, are both open systems in terms of energy and matter. The outermost region of the atmosphere, based on composition, is the system.
It should be noted that the forest simply means the large area of land that's covered with trees and undergrowth. In this case, it should be noted that a forest is an open system in terms of energy and that a forest is an open system.
In terms of matter and resources, the Earth is essentially a closed system, because matter and resources are fixed.In terms of energy, the Earth is an open system, because there is a balanced transfer of energy.
Therefore, Systems encountered in nature at Earth's surface, such as a forest, are open systems in terms of energy and matter. Thus, option B is correct.

The statement “force equals mass times acceleration (F=ma)” is Newton’s second law of motion. Why is this a law rather than a theory?
A-It states, rather than explains, the relationship between the variables.
B- .It cannot be proven, whereas a theory can be proven.
C-.It may be revised if new information shows that the relationship has changed.
D- It was classified as a law because it is related to other similar discoveries.
Answer: it’s A
Explanation:
Newton’s second law of motion is a law rather than a theory because: A. It states, rather than explains, the relationship between the variables.
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
[tex]Force = mass[/tex] × [tex]acceleration[/tex]
This ultimately implies that, Newton's Second Law of Motion is a law because rather than explain, it states the relationship between the three (3) variables;
Force.Acceleration.Mass.In conclusion, a law can be proven whereas a theory may be revised in the event that a new information shows that there is a change in relationship between the variables.

Two groups of tomatoes were grown under laboratory conditions, one with humus added to the soil (Group 1) and the other a control without humus (Group 2). The leaves of the plants grown without humus were yellowish (less green) compared with those of the plants grown in the humus-enriched soil. The best explanation for this difference is that the: Group of answer choices
Answer:
the humus contains the minerals necessary for chlorophyll synthesis
Explanation:
The yellowness of leaves in plants can be attributed to inadequate chlorophyll in the plant. The chlorophyll is responsible for the greenness appearance of the leaves of plants and when it is present in inadequate quantity, the leaves appear yellowish in color.
Some of the minerals necessary for the formation of chlorophyll include magnesium, nitrogen, and iron. It thus means that the humus supplied to the soil of group 1 plant has the necessary minerals to synthesize chlorophyll while the soil of group 2 plants is deficient in some or all the minerals required for chlorophyll synthesis.

explain which mixture most likely produced more ATP. The mixture of yeast and water only OR the mixture of yeast, water and sugar. Support your answer using observation and knowledge of cellular respiration.
Answer:
The mixture most likely to produce more ATP is the mixture of yeast, water and sugar
Explanation:
In cellular respiration metabolic reactions take place in the organism's cells that makes adenosine triphosphate, ATP, from the chemical energy in nutrients or oxygen with the release of waste products
Yeast which is a Eukaryotic organism produces an addition of or an extra 34 molecules of ATP per molecule of glucose, when placed in the presence or have access of glucose
A high proportion of the produced ATP are by aerobic respiration requiring oxygen
While yeast produces 2 ATP per molecule of glucose by glycolysis'
Therefore, more ATP is produced in the presence of sugar which is a disaccharide of glucose and fructose.

This is achieved by touching and feeling the the body inorder to determine the location,size,consistency or firmness, shape, tenderness and the texture of a body organ or to get the location of pain.
Palpation is mainly employed in physical examination of the abdomen and it can serve as a diagnostic approach to ascertain the presence of a disease condition or injury.
Palpation can be deep palpation (4-5cm) to feel internal organs of the body and to note any mass or tumour or light palpation(1-2cm) to feel surface abnormalities.
Answer:
palpation
Explanation:
The correct answer would be palpation.
Palpation is a medical term that generally refers to the process of using fingers to diagnose diseases or identify body abnormalities.
By using the sense of touch, different characteristics of the body region are assessed and the information is collated and critically examined to arrive at a diagnosis.

distinguish between red, green, and blue colors, which type of mutation is this?
OA.
somatic mutation
B.
Silent mutation
C. neutral mutation
D. harmful mutation
E. beneficial mutation
Reset
Next
Answer:
E
Explanation:
A mutation that confers phenotypic benefits to individuals or a group of individuals would be considered a beneficial mutation.
Mutation involves a sudden change to the gene coding sequence of the DNA. It can occur as a result of substitution, duplication, deletion, inversion, insertion, etc of purine or pyrimidine bases of the DNA.
These changes can be harmful, beneficial, or neutral to individuals. Those that have neutral effects in individuals are also called silent mutations.
In the case of a duplication causing trichomatic vision in humans, it represents a form of beneficial mutation because it enables humans to be able to distinguish between red, green, and blue colors. The ability to distinguish among these colors improves the quality of life of humans.
After getting the slide and microscope ready, Stella is eager to see the microscopic pond water specimen! She crouches around her microscope and aligns her eye with the microscope’s eyepiece. But she's only able to see a bright white light. At this point, no specimens or cells are visible on Stella's pond water slide. After taking a moment to collect her thoughts, Stella realizes she can't see any lifeforms because a.there are no specimens on the slide b.the microscope is not plugged in. c.she hasn't fastened the slide to the stage. d.the microscope is not yet in focus
Copied but correct answer.
Answer: C (She hasn't fastened the slide to the stage
Explanation:
In Microscopy even if the slide is not yet in focus,she will be able to see part of the slide which may appear as transparent image.Therefore this is a wrong answer.
If the microscope is not plugged it light can not come up.
If there are no specimen on the slide,the slide will still as transparent image at the focus.
No doubt Stella forgot to fasten the slide to the stage.,therefore the specimen on the slide was not in focus of the objective lens,rather she was focusing on the stage only,hence the visible white light.
Stella can not able to see any life forms in the microscope because she hasn't fastened the slide to the stage. Thus, the correct option is C.
What is Microscope?A Microscope may be defined as an instrument that constructs an enlarged image or view of a small object, thus illustrating details too small to be seen by the unaided eye.
If the microscope is not plugged in, Stella will not able to see even white light. If the microscope is not in focus, then Stella is able to see a transparent sheet of fil under it. No specimens also provide a transparent appearance.
But a view of white light indicates that she hasn't fastened the slide to the stage.
Thus, the correct option is C.
