What organisms carry out metabolism?
Answer:
Eukaryotes
Explanation:
Are organisms wise cells have a nucleus and membrane bound organelles. Prokaryotes are organisms whose cells lack a nucleus. Eukaryotes carry out cellular respiration with the help of mitochondria. Mitochondria are organelles that produce the enzymes necessary to catalyze the series of reactions that produce ATP.

What is difference between acid and bases?
Definition. A substance, mostly liquid that donates a proton or accepts an electron pair in reactions. An acid increases the concentration of H+ ions. A base is a substance that releases hydroxide (OH-) ions in aqueous solution, donates electrons and accepts protons.
(just if someone needs this i guess)
Answer:
Acids are sour, gives burning sensation, generally sticky, reacts with metals to produce hydrogen gas. Although bases are opposite as they are bitter, generally odorless (except ammonia), they are slippery; bases react with fats and oils. In phenolphthalein, indicator acids remain colorless, and base gives pink color.

Describe the following types of cell signaling:
Autocrine:
Juxtacrine:
Endocrine:
Paracrine:
Answer:
Autocrine:Autocrine signaling means the production and secretion of an extracellular mediator by a cell followed by the binding of that mediator to receptors on the same cell to initiate signal transduction. A well-characterized form of autocrine signaling is the secretion of IL-1 by macrophages.
Juxtacrine:In biology, juxtacrine signalling (or contact-dependent signalling) is a type of cell–cell or cell–extracellular matrix signalling in multicellular organisms that requires close contact. ... A membrane ligand (protein, oligosaccharide, lipid) and a membrane protein of two adjacent cells interact.
Endocrine:The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.
Paracrine:Paracrine signaling is a form of cell signaling or cell-to-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behaviour of those cells. ... However, the exact distance that paracrine factors can travel is not certain.

How do animals transport materials?
Answer:
Thought the process of discussion and ossmossis as due to gaseous exchange
Explanation:
With the aid of thin layers and large surface area animal are able to transport material thought the blood due to diffusion and osmosis In order to transport different materials from a every of high concentration to a low concentration until material is equally distributed throughout the body
Which of the following statements tells how facilitated diffusion differs from
simple diffusion?
A. Particles move through cell membranes without the use of energy by cells.
B. Particles tend to move from high concentration to lower concentration.
C. Particles move within channel proteins that pass through cell membranes.
D. Particles tend to move more slowly than they would be expected to move.
Answer:
I think its C but I am not sure, I hope this helps :)
Explanation:
The statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).
Diffusion (both facilitated diffusion and simple diffusion) refers to the movement of substances across biological membranes from an area of high concentration to an area of low concentration.
Facilitated diffusion and simple diffusion are two types of passive transport that do not require energy to move molecules/ions in favor of a concentration gradient.
In facilitated diffusion, specific membrane proteins known as carriers or channels help to the movement of substances in favor of a concentration gradient.
Conversely, in simple diffusion, small molecules (e.g. CO2 and oxygen) freely diffuse across a selectively permeable membrane in favor of a concentration gradient.
In conclusion, the statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).

Why are epithelial cells in membranes
packed tightly?
to keep organs connected
to protect organs
to form different layers
Answer:
to protect organs
Explanation:
Epithelial cells are cells found in the human skin. They are tightly packed cells which helps to protect organs in the human body.
The cells are divided into different layers with an inner part and the outermost layer.
The skin is the largest organ of the human body. It protects all organs from the external environment.

Students studying the workings of the kidneys completed an investigation. The students prepared four model cells by using dialysis tubing containing the same solution of blue dye and water. Each of the model cells originally had a mass of 10 grams. The students then placed each model cell in a beaker containing different concentrations of dye in water. After 24 hours, they recorded the mass of the model cells. Their data appears in the table.
Concentration of Water % Mass of Model Cell (g)
100 12
90 11
80 10
70 9
What is the most likely reason that the model cell placed in 100% water increased in mass?
Water reacted with chemicals in the model cell.
All of the water of the model cell evaporated.
Only half of the water entered the model cell.
Water diffused from the beaker into the model cell.
Answer:
Water reacted with chemicals in the model cell.
