A virus does not eat, use energy, or have cells. The correct option is C.
What is basically a virus?A virus is an infectious microbe made up of a nucleic acid segment (either DNA or RNA) surrounded by a protein coat.
A virus cannot replicate on its own; instead, it must infect cells and use host cell components to replicate itself.
Viruses are bundles of nucleic acid DNA or RNA encased in a protein shell called a capsid.
Viruses are the most abundant life form on the planet, according to some estimates; they are 10 times more numerous than bacteria.
Viruses could have evolved from mobile genetic elements with the ability to move between cells.
Thus, the correct option is C as a virus does not consume food, generate energy, or have cells..

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.

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.

What is the difference between cytokinesis in plant and animal cells?
Answer:
The primary difference between cytokinesis in plant and animal cells is that cellular reproduction is done sexually (meiosis) in animal cells, while cellular reproduction is done asexually (mitosis) in plant cells.
To better elaborate, Sciencing.com, states, "In plant cells, cytokinesis simply consists of the cell plate forming at the equator of the old cell that will soon be two. The cell plate–the future cell wall that will separate the two cells--divides the cytoplasm in half. . . . Cytokinesis in animal cells is more complex than in plant cells. A contractile ring, underneath the original cell's membrane, begins to form and contracts, which creates the cleavage furrow. The furrow grows deeper between the two cells until they pinch off and separate from one another, resulting in two separate daughter cells."

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

Which factor is a density-independent limiting factor?
Question 4 options:
availability of food
temperature
availability of water

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.

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.

Explanation:
Cell membrane is the cellular structure in an animal cell helps maintain homeostasis by controlling the transportation of substances into and out of the cell
what is homeostasis ?
Homeostasis is a self regulating process that maintain a stability of internal body with respect to the changing external environment which ultimately maintain a steady state of the living system.
It maintain body homeostasis by regulating body temperature, blood pH, blood glucose level, sodium, potassium and calcium ion concentrations.
Three mechanisms are involved in homeostasis such as Effector, Receptor, Control Center.
The homeostasis can be failed due to two factors such as due to an internal environment or other factors like Genetics, Physical condition, diet, nutrition, toxins, Psychological health etc.

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.
Ryan was born, he weighed 7 pounds.At 6 months, he weighed 11.2 pounds. Amanda weighed 6 ... Weighed 7 pounds.At 6 months, he weighed 11.2 pounds. Amanda weighed 6 pounds when she was born, and 12.9 pounds at 6 months. Which baby had a greater percent increase in weight? Explain. 2 Please Help Me!!
Answer:

Given:
Ryan weighed-
At born - 7 pounds
At 6 months - 11.2
Amanda weighed-
At born - 6 pounds
At 6 months - 12.9
Solution :
percent increase = difference in weight/initial weight
Ryan = 4.2/7 = 60%
Amanda - 6.9/6 = 115%
Thus, Amanda had a greater percent increase (115%) in weight.
Answer:
Sample response: The percent change in Ryan’s weight was 4.2/7, or 60%. The percent change in Amanda’s weight was 6.9/6, or 115%. Amanda had a greater percent increase in weight.
