Answer:
D
Explanation:
A somatic mutation cannot be passed down generations. The mutation has to be in the gamete (egg or sperm) to be inherited by the offspring. This can occur when the pre-gametic cells incur a mutation during development into a gamete.
Hmm... after some long thinking about this I would have to go with land. After land has been frozen, it thaws (<span>become liquid or soft as a result of warming.) Heat cannot "thaw" because it is apart of air. Water cannot "thaw" because it is already a liquid. Makes sense? I hope this helps! P.S. (A brainliest wouldn't hurt) ;)</span>
Answer:
<em>Most polymers are long chains of repeating, identical, carbon-containing molecules called monomers.</em>
Explanation:
Lipids are the exception because they have an additional, nonidentical molecule attached to each monomer chain. The additional molecule varies with the type of lipid.
Proteins are made of polypeptides, the monomer is an amino acid
Nucleic acid’s polymers are usually just referred to as RNA or DNA, depending on the variety of nucleic acids present.
Answer:
Deoxyribose
Explanation:
DNA stands for "deoxyribonucleic acid" because it has the sugar deoxyribose. It's named because it has one fewer oxygen than ribose. Be careful not to confuse the two sugars--ribose is in RNA, which stands for "ribonucleic acid."
Attached is a picture of the differences between the two sugars.
Answer:
You have found a limestone layer with numerous fossil corals, fossil sponges, and other fossils, little or no stratification, an absence of cross-bedding and ripple marks. In which environment was this limestone formed?
answer; an organic reef
Explanation:
An organic reef is a sedimentary rock structure of significant dimensions, erected by and composed almost exclusively of the remains of corals, algae, bryozoans, sponges and other sedentary or colonial organisms.
