Answer:
earthworm taking soil for nutrition
Explanation:
it's consuming the energy unlike the rock
An earthworm taking in soil for nutrition is another example of an open system, option B is correct.
An open system is characterized by its ability to exchange matter and energy with its external environment. In the case of an earthworm, it actively takes in soil for nutrition, breaking down organic matter and absorbing nutrients through its digestive system. This process allows the earthworm to grow, reproduce, and carry out essential life functions.
The exchange of soil, nutrients, and gases (such as oxygen) occurs continuously, sustaining the earthworm's biological activities. In contrast, a rock in a field does not interact with its environment in the same way. It remains a closed system, passively experiencing natural forces without actively receiving external inputs or engaging in metabolic processes, option B is correct.

Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks. One tree is left outside in normal conditions. The heights of the trees are measured once a week. What is the Independent Variable: What is the Dependent Variable? What is the controlled variable?
Answer: Height
Explanation: IV diverse stickiness levels, DV height CV, same tree type(redwood), time (12 weeks) – tree left external I typical conditions is likewise viewed as a benchmark group as it encounters no mugginess change.
The various variables can be grouped as :
Independent variable; Humidity levels
Dependent variable; Heights of the trees
Controlled variable ; Green house
The independent variable is the variable that not affected by the change in other variables, it determines the outcome of an independent variable in an experiment. and from our question the independent variable is the different humidity levels inside the Greenhouse
Dependent variable is the measured variable in an experiment which is primarily dependent on the Independent variable, it can be likened to be effect/result of an experiment ; height of the trees
A controlled variable is a variable that is held constant during an experiment because it doesn't have a direct importance on the aim of the experiment, but it can affect the outcome if not controlled ; Green house
Hence the independent variable = Humidity levels, Dependent variable = height of trees and the controlled variable = green house

A person counts the number of flowers she sees on different types of plants she records the data every week what is the independent variable dependent variable constant and control
Answer:
Independent variable: Different types of plants
Dependent variable: Number of flowers
Control group: None in this experiment
Constant: same time of recording
Explanation:
Independent variable in an experiment refers to the variable that is manipulated or changed by the experimenter in order to effect a response. In this experiment, the independent variable is the DIFFERENT TYPES OF PLANTS USED because it is what is changed by the person.
Dependent variable is the variable that the experimenter measures or records. In this case, the dependent variable is the NUMBER OF FLOWERS recorded for each type of plant.
The control group of an experiment is the group that does not receive any experimental treatment i.e. group placed on normal conditions for comparison. In this experiment, NO CONTROL GROUP was used or mentioned.
The constant or controlled variable is the variable that is kept constant or unchanged throughout the experiment in order not to influence the outcome. In this experiment, the person records the number of flowers on each plant at the SAME TIME (every week), hence, it is the constant.

Should I drop out of University? I am a biology major, and I didn't realize that it's very intense and tedious. I have two labs every week, I barely get chance to study during the weekdays. I don't mind studying, I'm just not used to the overload. I am bad at time management and I became unmotivated. What do I do?? If you're in college please give me advice. **IF YOU'RE NOT IN COLLEGE DO NOT ANSWER (since it doesn't apply to you)**
*Not in college but im a senior in college classes*
d I wouldn't say dropping out is the best answer, but I do know that come colleges/universitys offer major changes. I would see if yours offers that option. I'm also terrible at time management and movitivation. I know it doesn't sound like much fun, but I normally have a study day that I dedicate to studying. Last year it was Sunday, since I didn't have school and I'm already home with church. But this year I've been using monday and thursday as my study days.
I know it gets hard, and a lot of things are uncertain lately, but it'll be okay. You can do it, good luck!

How does the size of a pure substance affect its density? ( Only claim is needed for CER)
Answer:
See the answer below
Explanation:
The size of a pure substance has no effect on its density.
The density of a pure substance which is the ratio of the mass and the volume of the substance is constant. Mathematically, the density is expressed as:
Density = [tex]\frac{mass}{volume}[/tex]
This means that for every increase in the mass of a pure substance, the volume will increase measurably and vice versa. Under normal conditions, it is practically impossible to increase the mass of a substance without increasing the volume of the substance. It is also not possible to increase the volume of a substance without increasing the mass of the substance.
Hence, the density will always remain constant irrespective of the size of the substance.

How is the cell membrane's function similar to a structure in a school? Use an analogy and justify your answer
Answer:
The cell membrane can be compared to the school gates.
Explanation:
Cell membranes only let in specific molecules (people), large substances (old people) cannot cross it while smaller molecules like oxygen (students) can easily pass through the membrane.
Comparable to the school gates is the cell membrane, cell membranes only let particular molecules (people) flow through larger substances (old people) and cannot do so.
What is the function of the cell membrane?A cell is shielded by its plasma membrane, often known as its cell membrane. The membrane serves a variety of purposes and also creates a stable environment inside the cell.
All cells include a membrane that divides the inside from the external environment. This membrane is known as the cell membrane or the plasma membrane.
Therefore, the gate acts as a cell membrane's function similar to a structure in a school the cell membrane controls the movement of materials into and out of the cell.

It has been crumpled and folded, while the other layers lie flat. B. Other layers have been deposited above it. C. It is horizontally-oriented. D. It cuts through all the other layers.
Answer:
D. It cuts through all the other layers.
Explanation:
The upper layers, those that are closest to the surface of the Earth, are the newest layers to be laid down. Layers below are older. Since sedimentary rocks form on top of each other, it is very easy to see Earth's geologic history in areas where this type of rock is found.
The rock layer is older than the surrounding strata D. All the other layers are pierced through by it.
Which four rock strata are there?Above other rocks, this one is the youngest. Oldest rock: The rock formation is situated beneath all others. This rock stratum is immediately above the second-oldest. the erosion above: After the older rocks was slanted and worn away, this layer developed on top of them.
Why is there a rock layer?Typically, sedimentary rocks are found in horizontal layers known as strata. Younger strata sit on top of older layers in undisturbed strata. The superposition law governs this. Other geologic elements, such as fractures or intrusions, can cut strata. A crack is a gap in Earth's surface.

Chemical Reactions occur faster with the presence of enzymes as long as the conditions are ideal.
Answer:
Yes, enzymes speed up chemical reactions. The enzyme speeds up the reaction by lowering the activation energy level.
Here, we are required to explain why chemical reactions occur faster with the presence of enzymes as long as the conditions are ideal.
True, Chemical reactions occur faster with the presence of enzymes as long as the conditions are ideal.Enzymes are the biological form of chemical catalysts.
Enzymes are able to make chemical reactions occur faster by lowering the activation energy of these chemical reactions.However, enzymes have active sites and are therefore specific in their actions and consequently, the chemical reactions they can influence.

A geneticist is studying two traits in the fruit fly - eye color and wing shape. They perform a dihybrid cross. If the genes for these traits are not linked, what proportion of the F2 offspring will be expected to display the dominant phenotype for eye color and recessive phenotype for wing shape
Answer:
3/16
Explanation:
According to Mendel's law of independent assortment of genes, when a dihybrid cross involves two genes that assort independently and one of the parents is dominant for the two genes and the other is recessive, the phenotypic ratio of the offspring at F2 would be 9:3:3:1. The proportion of the offspring with the dominant parental traits would be 9/16, those with the recessive parental traits would be 1/16, while those with mixed traits would be 3/16 each.
Assuming the eye color is represented by E and the wing shape is represented by W. At F2
EeWw x EeWw
E_W_ - 9/16 (dominant for both eye color and wing shape)
E_ww - 3/16 (dominant for eye color and recessive for wing shape)
eeW_ - 3/16 (recessive for eye color and dominant for wing shape)
eeww - 1/16 (recessive for both eye color and wing shape)
Hence, the proportion of the offspring with dominant phenotype for eye color and recessive phenotype for wing shape would be 3/16.
