What does active transport and facilitated diffusion have in common?
Both active transport and facilitated diffusion are methods of moving substances across cell membranes. Active transport requires energy input to move substances against their concentration gradient, while facilitated diffusion does not require energy and moves substances along their concentration gradient with the help of transport proteins.
A type of algae grows on a sloth. What must be true for the algae and the sloth to have a commensal relationship?
A commensal relationship requires that one organism benefits from the relationship without affecting the other organism. So, in order for that to be true, the algae would have to be neutral to the sloth... not harming it or aiding it (those relationships would be defined differently). It would have to not affect it at all.
Would a lion eat cat food?
A lion is a carnivore and typically requires a diet of raw meat to meet its nutritional needs. They would not typically eat cat food as it does not provide the necessary nutrients for their health and development.
Why do animals need a continuous supply of oxygen?
Animals need a continuous supply of oxygen because it obtains energy from their food. To acquire such energy from food, cells in animals require a steady supply of ATP in order to function. To produce this ATP, cellular respiration requires oxygen. Without ATP, cells and the organism will die so therefore, animals need a continuous supply of oxygen to survive.
Active transport is the process of what?
Active transport is the process by which a cell uses energy to move molecules or ions across a cell membrane against their concentration gradient. This process requires the use of ATP energy to pump substances from an area of low concentration to an area of high concentration.
What is a chemical substance that an organism requires to live?
One example of a chemical substance that an organism requires to live is water. Water is essential for various biological processes such as nutrient transport, temperature regulation, and waste removal.
A chemical substance that an orgamism requires to live is called?
A vital chemical substance that an organism requires to live is called a nutrient. Nutrients can include elements like carbon, hydrogen, oxygen, nitrogen, and essential minerals that are necessary for the organism's growth, development, and metabolism.
What organism must obtain nutrients and what?
Every living organism must obtain nutrients to survive. These nutrients typically include carbohydrates, proteins, fats, vitamins, and minerals that are necessary for processes like growth, repair, and energy production.
When liquid becomes a water vapor is that a chemical reaction?
no. chemical reaction requires a new substance to be created
Because change the identity of the substances involved they are hard to reverse?
Chemical changes are hard to reverse because they involve the formation of new substances with different chemical properties than the original substances. This typically requires energy input or a specific reaction pathway to revert back to the original substances, making the process difficult to reverse.
Is an onion considered a living organism?
Yes, an onion is considered a living organism because it is made up of cells, requires energy and nutrients to grow, and exhibits characteristics of life such as responding to stimuli and reproducing through its seeds.
What organism requires a second organism of the opposite sex in order to reproduce?
The penis requires a vagina in order to reproduce.
What can be broken down into simpler substances by chemical but not physical means?
A chemical compound can be broken down into simpler substances by chemical means. This involves breaking the bonds between atoms within the compound, resulting in the formation of simpler molecules or elements. This process typically requires the addition or removal of energy.
Why the yeast active in soda but not active in water?
Yeast is a living organism and thus requires nutrition. In soda, there are sugars and other nutrients not present in water which promote the growth of yeast.
What weathering process usually requires water apex?
Chemical weathering typically requires water, as it involves the breakdown of rocks through chemical reactions with water and substances dissolved in it. Water can dissolve minerals in rocks, leading to their decomposition and alteration. Water also facilitates the transport of ions and molecules involved in chemical weathering processes.
Which process usually requires water?
Chemical weathering
Can a tissue sample grow bigger?
No, a tissue sample cannot grow bigger on its own. The growth of tissue requires a living organism to provide nutrients and undergo cell division. A tissue sample outside of a living organism will not grow in size.
