The most important physical fitness for your and middle aged
adults is cardiorespiratory endurance as this measures the capability and
health of the heart, muscles and lungs in making sure that they are strong
enough and making the body work enough and to be fit, this is a component in
enhancing a maintaining a good health to an individual.
I think the mean DNA but don't quote me on that.
The process of protein synthesis involves two steps such as transcription and translation. In the process of transcription the encoded information in the DNA is transcripts or encoded into messenger RNA or mRNA inside the nucleus. This mRNA then comes out of the nucleus to the cytoplasm. In the process of translation the mRNA molecule attach with the ribosomes and tRNA molecules to synthesise the protein.
Answer:
Among others, two adaptations might be
- Avoiding corporal heat loss
- Increasing oxygen absorption
Explanation:
Up in the mountains, there is low oxygen, food is scarce, and adverse meteorological conditions. Animals and plants need to develop different strategies to survive. These adaptations involve not only physical and physiological changes but also behavioral changes. To mention a few adaptations, we can name:
- Avoiding heat loss. Temperature tends to be very low at highs, so, to <u>avoid heat loss,</u> animals develop shorter legs, tails, and ears. By doing this they reduce the area or surface of heat loss and also avoid getting frozen. In mammals, the coat is also very important. A thick coat helps them maintain a constant body temperature and keep warm. Some amphibians might also develop a thicker skin as they can not regulate their temperature, and it also helps them not to dehydrate.
- Camouflage: Coat is also helpful in camouflaging. Mammals´ hair color depends on their environment. Some animals, such as hares, can also change their fur color depending on the season. During snow seasons they turn white, and during the warmer season, they turn yellow or brown.
- Size and metabolism: Small mammals lose heat very fast, so they need to keep active and feeding most of the time. They have an elevated metabolism to keep warm. On the contrary, big animals, such as bears, need to hibernate to reduce their metabolism and get to survive, otherwise, they would need many reserves to cover their energetic requirements.
- Oxygen absorption: Some animals have adapted to the lack of oxygen by increasing their heart and lungs capacity as well as their capability to absorbing more oxygen from the blood.
