Blood plasma transports nutrients, waste (like uric acid, creatinine, and ammonium salts), albumin (protein), and electrolytes.
Answer:
Due to presence at early days of the planet.
Explanation:
We only find the remains of single celled organisms in the oldest fossils because the single celled organisms are the organisms that were present in the early days of this planet. These single celled microbes were present about 3.7 billion years ago while on the other hand, the oldest rocks are only a little older i. e. 3.8 billion years so these single celled organisms are considered as oldest fossils on this planet.
A single cell RNA seq analysis identifies 25 population of epidermal cells .
<h3>What is single cell transcriptomics used for?</h3>
Single cell transcriptomics are being used to create reference maps of healthy human tissues, organs and systems at single cell resolution.
An essential model system for studying stem cells and tissue regeneration is the mouse epidermis with its hair follicles. To demonstrate how the cellular heterogeneity of the murine telogen epidermis is controlled at the transcriptional level, we used single-cell RNA-sequencing in this study. 25 different populations of interfollicular and follicular epidermal cells were identified by impartial clustering of 1,422 single-cell transcriptomes. With previously unheard-of resolution, our data allowed for the reconstruction of gene expression patterns during epidermal development and along the proximal-distal axis of the hair follicle.

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.
