Answer:
Nucleotides contain three characteristic components: a nitrogenous base, a pentose, and one or more phosphate groups.
Explanation:
It's considered a natural resource because it is energy that is not man made.
It's a renewable energy because it naturally gets replaced.
A food establishment
is an operation that stores, prepares, packages, serves, vends, delivers
or otherwise produces food for human consumption. Food that is offered in food establishments
should come from local-approved food sources. They can use produce that they
grow themselves or from agricultural producers that should be licensed and are responsible
to assure that their produce is safe (complying applicable laws). The producer
has to have a United States Department of Agriculture inspected plant. Food
establishments should obtain produce from those who have been certified in Good
Agricultural Practices and Good Handling Practices.
Answer:
B.Active transport, because energy is being used to move molecules against the concentration gradient
Explanation:
Substances move in and out of living cells through various transport means. Some substances move passively (without energy) while others move actively (with energy). Active transport of substances involves the movement of molecules against the concentration gradient.
Active transport moves against concentration gradient in the sense that the movement occurs from a region which is less concentrated to one which is more concentrated, hence, energy input in form of ATP is required for such transport to occur. This is the case of the cellular transport in the diagram. Therefore, it is an ACTIVE TRANSPORT because energy input (ATP) is required.
Note, Osmosis and facilitated diffusion are types of passive transport that requires no energy to occur.
Answer:
Physical adaptations do not develop during an individual animal's life, but over many generations. The shape of a bird's beak, the color of a mammal's fur, the thickness or thinness of the fur, the shape of the nose or ears are all examples of physical adaptations which help different animals survive.
