12C, 13C,and 14C are called isotopes because they are all the same element
Answer:
6 thymine, 4 guanine. 4 cytosine
Explanation:
Adenine pairs with thymine, so you need 6 of each
Cytosine matches with guanine, but the total of nucleotides is 20, so
6(adenine)+6(thymine)=12
20-12=8
8= 4(guanine)+4(cytosine)
Answer:
Most kingdoms are Eukaryotic
Explanation:
Prokaryotes are organisms consisting of cells that do not have membrane-bound organelles or a cell nucleus.
Eukaryotes are organisms made up of cells that have a membrane-bound nucleus to hold their genetic material, in addition to membrane-bound organelles.
The five kingdoms are Animalia, Plantae, Protista, Fungi, and Monera.
Animalia are eukaryotic because the organisms in this category are advanced organisms that require membrane-bound organelles and a nucleus with their genetic DNA in order to function and thrive. Protista, fungi, and plantae also go into the eukaryotic category because protists, fungi, and plants all have membrane-bound organelles and can carry out higher-level functions.
Monera are prokaryotes, and monera are usually classified into two domains: bacteria and archaea. Monerans lack a nucleus and membrane-bound organelles, and for this reason Monerans are very small organisms.
Answer:
They are located in the retina (a layer at the back of the eye).
