Closed and Open Systems
An open system is one that receives input from
outside the system. For example, your body is an
open system because it receives food and oxygen
from outside the system (your body). What is another
example of an open system?
A rock in a field
An earthworm taking in soil for nutrition
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.

Which of these micropipetters would serve best to deliver 55 microliters?a. 0.5 to 10 µL micropipetter b. 10 - 100 µL micropipetter c. 50 - 1000 µL micropipetter
Answer:
b. 10 - 100 µL micropipetter
Explanation:
The micropipetters that would serve best to deliver 55 microliters would be the one which has a volume capacity of 10-100 µL.
This is because it will be easier to measure 55 micro liters from the Pipette which has a standard range of 10-100 microliter.
0.5 to 10 µL doesn’t fall within the range and it will be very hard measuring the volume.

What happens after mitosis is complete?
Once the mitosis is complete, the entire cell is divided into two by the way of a process called cytokinesis.
When the concentration of a substance higher on one side of the cells selectively permeable membrane, certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy. This process is called
A.passive transport
B.active transport
C. Mitosis
D. Replication
Answer:
A.
Explanation:
osmosis and diffusion are both passive transport bc it doesnt require energy and only moves down cocentration gradient, never against concertration gradient. Give me a brainliest if i helped! ♡
When certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy, the process is called passive transport.
When diffusion takes place between compartments separated by a membrane permeable to that solute, it is called simple diffusion.
Passive transport does not require any additional energy other than the movement of the molecules, moving these in favor of their concentration gradient.
In other words, simple diffusion does not require ATP expenditure, since it is a spontaneous phenomenon.
The molecules that are mobilized by simple diffusion through the membrane are the nonpolar and small, the fat-soluble and the small polar ones, but without a net electric charge, such as H2O.
In the particular case of H2O, passive transport is called osmosis, the passage of water through the membrane by osmosis always takes place spontaneously and very quickly.
H2O will diffuse from the compartment with the lowest concentration of solutes or hypotonic medium, to the compartment with the highest concentration of solutes or hypertonic medium, in such a way as to equalize the concentrations in both compartments.
Therefore, we can conclude that when certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy, the process is called passive transport.

Answer the following question. How might the human condition be improved through biological and environmental
engineering?
Answer:
This chapter examines the range of human consequences of, and responses to, global environmental change. We begin by developing the concept of human consequences and showing why, to understand them, it is critical to understand the variety of human responses to global change. We then offer a framework for thinking about human responses and discuss the pivotal role of conflict. The next section examines three cases that illustrate many of the major factors influencing the human consequences of global change. The following sections describe the human systems that are affected by or respond to global change, and how they interrelate. We conclude by offering some general principles for research and some research implications.

How do the hypothesis of microspheres and the RNA World hypothesis build off of each other?
Answer:
Microspheres are formed of proteins. It has been found that when an amino acid is permitted to get desiccated, then this amino acid produces proteins that in turn give rise to microspheres.
On the basis of the RNA world hypothesis, the first genetic substance was considered to be an RNA, and then later the DNA turned out to be the genetic substance of higher species during the passage of evolution. It was also believed that microspheres comprised encoded information within it, and at the time of the splitting of microspheres, this encrypted information may have got transferred to the upcoming generation.

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.

9) What trend do you notice about carbohydrates in the graph above?
your help is appreciated thanks ! :)
Answer:
carbohydrates burn within 2 hours after eating while lipids last 6 hours
Explanation:
carbohydrates are short term energy
and lipids are longer term of energy
The trend which can be noticed about carbohydrates in the graph above is that it increases the blood sugar level than the other food type.
In Science, biological macromolecules are mainly grouped into four (4) categories and these are;
Lipids.Nucleic acid.Proteins.Carbohydrates.Carbohydrates are typically found in energy-giving foods and they aid in the proper functioning of the body of a living organism such animals and human beings.
Also, carbohydrates are broken down in the body into sugar but not proteins or fat.
This ultimately implies that, an increase in the intake of carbohydrates can cause a subsequent increase in the blood sugar level.
Based on the graph above, we can deduce that carbohydrates increases the blood sugar level than the other food type.
