Match the following organelles to their function or structure. Each organelle is only used once!!!
Cell membrane
Controls the passage of materials into and out of a cell
Flagella
Acts as a whipping propeller, moving a cell through its environment
Lysosomes
Digest foreign substances and worn out cell parts
Mitochondria
Ribosomes
Makes proteins
Cilia
Nucleus
Protects DNA and is considered the “brain” of the cell
Golgi Apparatus
Modifies and packages proteins
DRAG & DROP THE ANSWER
Produce energy (ATP)
Structures shaped like small oars that beat in unison to move the cell or the liquid around it
Answer:
Cell membrane - Controls the passage of materials into and out of a cell
Flagella - Acts as a whipping propeller, moving a cell through its environment
Lysosomes - Digest foreign substances and worn out cell parts
Mitochondria - Produce energy (ATP)
Ribosomes - Makes proteins
Cilia - Structures shaped like small oars that beat in unison to move the cell or the liquid around it
Nucleus - Protects DNA and is considered the “brain” of the cell
Golgi Apparatus - Modifies and packages proteins
Explanation:
The cell membrane separates the inside of the cell from the external environment, and regulates substances that enter and leave the cell.
The nucleus contains the genetic material of the cell, and therefore controls all cellular activities. It is also the site of transcription of mRNAs. mRNAs are translated at ribosomes.
The ribosomes are like factories that synthesize proteins through the process of translation.
When proteins have been produced, they are modified, packaged, and transported to their specific sites by the Golgi apparatus.
Mitochondria are energy-producing organelles - the site of cellular respiration.
Lysosomes are membrane-bound sacsin which waste products are digested
Some cells have cilia, which are hair like-structures that beat in unison to aid in locomotion. Another locomotory organelle is the flagella, which is a whip-like structure that helps some single-celled organelles to move.

20 Edmentum. All rights reserved.
Answer:
The type of data that is recorded by electrocardiogram is the electrical activity of the heart.
Explanation:
The heart functions through a nerve structure —the sinus node, the atrioventricular node and the His-Purkinje system— which determine the functioning of the organ through electrical activity.
The electrocardiogram, or EKG, is a device that records the electrical activity of the heart. This allows us to know any alteration in said activity, such as arrhythmias, interruption of electrical impulses or alteration of the heart's anatomy.
In order for the EKG to be able to record the electrical activity, electrodes must be placed on the limbs and chest, which are the sensors in charge of receiving the information of the heart's electrical activity.
Other options are not correct because:
The amount of oxygen in the blood is measured by using oximeters or blood gas measurement. The sound or the force from the heart beating can be recorded by auscultation with a stethoscope.Step 1: Identify which nucleic acid the following strand is. 5' TAC - ACT -

what is animal behavior?Animal behavior can be defined as all the ways animals interact with other organisms with its physical environment.
Behavior can be defined as a change in the activity of an individual in response to a stimulus, an external or internal cue or combination of both cues.
The causes of these behavior and how it develops in an individual, how it benefits an organism, and how it evolved.
Some behaviors are innate type or genetically hardwired, while others are learned, or developed through experience. In many cases, behaviors have both an innate component and a learned component.
Behavior is shaped by natural selection. Many behaviors directly increase an organism's fitness, that is, they help it survive and reproduce.

What reaction occurs in the stroma of the chloroplast?
Group of answer choices
Krebs Cycle
Light Independent Reactions
Light Dependent Reactions
Glycolysis
Answer:
Light Independent Reactions
Explanation:
The stroma is the fluid-filled space of chloroplasts the thylakoids. It contains all the enzymes required for light-independent reactions of photosynthesis and is, therefore, the site of the Calvin cycle.
The Krebs cycle and glycolysis are stages of cellular respiration and occur in the mitochondria.
The light-dependent reactions occur in the thylakoids
35. Which statement best describes the cell membrane of a living plant cell?
A. It selectively regulates the passage of substances into and out of the cell.
B. It is composed of protein and carbohydrates only.
C. It has the same permeability to all substances found inside or outside the cell.
D. It is a double protein layer with floating lipid molecules.
Answer:
The cell membrane of a living plant cell selectively regulates the passage of substances into and out of the cell (option A).
Explanation:
The plasma membrane in a living plant cell is composed of a double lipid layer that gives it hydrophobic character and acts as a semi-permeable barrier. The partial permeability of the substances allows regulating the passage of substances from and to the interior of the cell.
At the level of the plasma membrane there are several mechanisms and transport to allow the entry of substances needed for the cell or the output of synthesized products or metabolic waste, thus regulating the passage of substance in a selective way.
Regarding the other options:
B. Plasma membranes are composed of lipids, not just carbohydrates and proteins.
C. Permeability is not for all substances, but is selective.
D. Plasma membrane is a lipid bilayer, not a double layer of proteins.

Not all macromolecules are created equal. Explain why you would get more energy from eating a cheeseburger than you would from eating an apple. Be sure to include specific macromolecules in your response.
Answer: Carbohydrates are the body’s main source of energy. The fruit, vegetables, dairy, and grain food groups all contain carbohydrates.
Carbohydrates are the body’s main source of energy but Fats give you more energy. They help the body absorb certain vitamins. Many foods naturally contain fats, including dairy products; meats, poultry, seafood, and eggs; and seeds, nuts, avocados, and coconuts.
The burger would have more energy from eating it because it has a large amount proteins in it that can help your body. A apple can give you energy too because it is a carbohydrate but it wouldn’t be enough.

Which factor is a density-independent limiting factor?
Question 4 options:
availability of food
temperature
availability of water
disease
Answer:
The correct answer is temperature.
Explanation:
I took the test.
The density-independent limiting factor is any force that affects the size and population, temperature, hence option b is correct.
What is the density-independent limiting factor?In ecology, a density-independent factor is any force that has an impact on the size of a population of living creatures regardless of the population's density.
This term is also known as a limiting factor (the number of individuals per unit area). These density-independent causes include nutritional or food scarcity, environmental contaminants, and harsh weather.
Natural catastrophes, seasonal patterns, odd weather, and human activities are density-independent influences.
Therefore, in addition, catastrophes like fires, temperatures, and storms can have an effect on population increase, hence option b is correct.
