I. Each carbon atom can form single bonds with up to four other carbon atoms. II. Each carbon atom can form double bonds with up to two other carbon atoms. III. Carbon atoms can join together to form chains or rings. IV. A single molecule of some compounds can contain thousands of carbon atoms.
Answer:
All the given choices
Explanation:
Carbon is a very interesting element which is the backbone of most organic compounds.
Organic compounds are made up of carbon. Carbon forms a wide range of compound due to the following properties;
- An atom of carbon has 4 valence electrons and can bond with 4 other carbon.
- Carbon can form single, double and triple covalent bonds.
- They can join together to form rings or chains.
Answer – C. If the seed shape did not have a clearly dominant form
In doing his research on inheritance, Mendel studied seven different traits in peas, namely – height, flower color, seed color, and seed shape. Actually in Mendel’s study, seed shape had a very clear dominant form; having a smooth seed was a dominant trait and having a wrinkled seed was a recessive trait. If this clear dominant form could not be established, then Mendel’s experiment would have ceased to progress. Option B is not the answer because rate of reproduction was not one of the features that Mendel studied in the research. Options A and D are not the answers because they were the actual findings of the study.
Answer:
-3
Explanation:
because when you do this math solution you get -3
I believe the answer, homologous structure, is what you are looking for
<u>afferent signals</u> flow inward to the central nervous system from sensors in the periphery, while <u>efferent signals</u> flow outward from the central nervous system to the periphery.
