Swimming works the heart and lungs. This trains the body to use oxygen more efficiently, which is generally reflected in declines in the resting heart rate and breathing rate.
Answer:
The correct answer to the question is: 1) free in the cytoplasm.
Explanation:
- Ribosomes are responsible for synthesising polypeptide chains by the process of translation from mRNA or messenger Ribonucleic Acid.
- They are found free in the cytoplasm or remain bound to the Endoplasmic Reticulum (ER) to form the Rough Endoplasmic Reticulum (RER).
- The cytoplasmic proteins are synthesised by the free ribosomes.
- The membrane proteins, secretory proteins and the organelle specific proteins are synthesised by the Ribosomes located on the Endoplasmic Reticulum.
- This is because these proteins need to be translocated to the target organs through vesicles that buds out of the ER and and the Golgi bodies.
- As the luciferase polypeptide is located in the cytoplasm, it is synthesised by the free ribosomes present in the cytoplasm.
Answer:
All their descendants will be heterozygous for the skin color, Bb, expressing blue skin.
Explanation:
<u>Available data</u>:
- Smurfette has light blue skin
- Her family is a "true bred" or "purebred" line.
- She married a boy who has light yellow skin
- blue skin is the dominant trait expressed by the B allele
- yellow skin is a recessive trait, expressed by the b allele
Cross: Smurfette x Husband
Parentals) BB x bb
Gametes) B B b b
Phenotypes) blue skin yellow skin

b Bb Bb
b Bb Bb
F1) 100% of the progeny will be heterozygous for the skin color, Bb
100% of the progeny will be blue-skinned.
Note: Although the progeny is blue-skinned, they are not true-bred anymore.
Answer:
Predation and Competition. Two of the main ways that populations interact with one another is by competition and by predation. In competition, individuals seek to obtain the same environmental resource. In predation, one population is the resource of the other.
