Write two sentences using the vocabulary words above about plant cells:
Answer:
Cells are the basic unit of a living organism and where all life processes are carried out. Animal cells and plant cells share the common components of a nucleus, cytoplasm, mitochondria and a cell membrane. Plant cells have three extra components, a vacuole, chloroplast and a cell wall.
Explanation:
After cooking the hot dogs, your friend's mom reminds you not to leave the grill out, or the iron (Fe) in the grill will react with oxygen (O2) in the air to produce rust (Fe2O3). a. Write a balanced equation for this reaction. Be sure to show your work.
Answer:
Explanation:
Oxygen gas and water must be present for iron to rust.
A region of the metal’s surface serves as the anode, where oxidation
occurs:
Fe(s) → Fe²⁺ (aq) + 2 e⁻
The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:
O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)
The overall redox reaction is:
2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)
The Fe²⁺ ions formed at the anode are further oxidized by oxygen:
4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)
This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.

Explanation:
There are four kinds of tissues in the human body. They are muscle, nervous, connective, and epithelial tissues. Which of the following is true about all of these tissues?
Answer: Epithelium tissue refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. Connective tissue binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart. Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body
Explanation:
Which of the following words describe most of the trillions of cells in your body?
A. Specialized
B. Undifferentiated
C. Pluripotent
D. Embryonic
Answer:
A. specialized
Explanation:
A cell is the basic unit of life. However, there are many different types of specialized cells. This means they are modified by size, shape, or function according to their purpose. Specialized cells make up tissues, tissues make up organs, and organs make up the systems that work together to make up our bodies.

Explanation:
____allows some things to enter and leave cells, while keeping other things in the cell or keep other
things out of the cell.
A:fermentation
B:A selectively permeable membrane
C:metabolism
D:osmosis
Answer:
The cell membrane is the outer layer of the cell. The primary function of the cell membrane is to regulate what substances enter and leave the cell. The cell membrane is selectively permeable, or "semi-permeable", meaning that the membrane only allows certain substances to enter or leave the cel
Answer:
b
Explanation:
because the membrane of a cell is responsible for what enters n leave the cells.
it can't be "D" because osmosis is the process by which water molecules enter a permiable or semi permiable membrane of an object from an area of high concentration to an area of low concentration.
fermentation is the process by which chemical changes occur in an organic matter do the answer is definitely not A
metabolism is the chemical processes that occur in an organism to maintain its life so the answer is not c

What direction will solutes move if a protein pump is functioning properly?
Answer:
Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane.

Answer:
Spiders grow from eggs, to spiderlings, to spiders. Insects grow from eggs, to larvae, to insects.
Explanation:
Hope you have a great day :)
In the life cycle of a Spider, there are no larvae, pupae, or nymphs stage.
Explain the life cycle of a spider.The first stage, egg
When a female has mated, she stores her spermatophores until she is ready to lay her eggs. The number of eggs is between a few and tens of thousands.
The second stage, egg sacs
The progeny develops in the egg sac, which was designed to shield the eggs from the weather and from predators like birds and ants.
The third stage, spiderlings
The young spiders that resemble their parents the most are called spiderlings.
The fourth stage, adults
The majority of spider species mature in five to ten molts. The spiderlings are prepared to reproduce and restart the life cycle once they reach adulthood.

In order to maintain homeostasis, the human body must be able to get rid of the waste products produced by cellular processes. The kidneys, for example, are responsible for removing waste from the bloodstream by producing urine. Urine produced in the kidneys then travels through the ureter and into bladder, and is finally expelled from the body by the urethra. The kidneys, ureter, bladder, and urethra help the body maintain homeostasis through the process of what?
