Benefits of living on land: Sunlight is brighter, since it doesn't have to go through water first. More carbon dioxide in the atmosphere than in the ocean. Mineral nutrients are plentiful in the soil.
When
the morning announcements call for you to rise to recite the pledge of
allegiance, the signal to stand up on your feet is sent by the somatic nervous system. The somatic nervous system is <span>part of the peripheral nervous system. Its functions are : </span><span>voluntary movement of the muscles and organs and reflex movements. So, the signal to stand up on our feet in the morning is movement of the organs sent by this system. </span>
Answer:
1. rRNA helps form ribosomes. mRNA provides the instructions for proteins to the ribosome. tRNA transfers amino acids to the ribosome, which are needed to create the protein.
2. The Central Dogma of Biology states that DNA holds the instructions for protein creation. These directions are copied by RNA, which the RNA then utilizes to create protein. (Also known as DNA to RNA to protein.)
3. Proteins are made in the ribosomes, which are small organelles inside a cell.
4. They are both nucleic acids. Both of them store genetic information. They also share the same basic components: sugar, phosphate backbones, and nitrogenous bases.
5.
a. RNA is single stranded; DNA is double stranded.
b. RNA contains uracil as a base instead of thymine.
c. RNA has ribose, while DNA has deoxyribose instead (hence the differences in their name: RNA means ribonucleic acid. DNA means deoxyribonucleic acid).
6. mRNA (messenger RNA), rRNA (ribosomal RNA), tRNA (transfer RNA)
Explanation:
The statement that is true is that the offspring will have the probabilities of 100% Dd or dominant allele for dimples. The offspring are heterogeneous to the genome. This mean the recessive allele will be mask by the dominant allele.
Answer:
This process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay. The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.
