Answer:
In the bloodstream
Explanation:
The metabolic breakdown of amino acids creates ammonia, which is especially toxic to the brain. The liver converts ammonia to urea, and it is then released into the bloodstream, where it travels to the kidneys and is excreted in the urine.
Answer:
The element carbon is actually the chemical basis for all life. It is the most important because it can be used to form many essential compounds.
Carbon takes up almost 20% of the weight of an organism, and it is essential for them to live and grow. (Also to reproduce.)
Answer:
These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.
Answer:
The Rhizaria are supergroup species of mostly unicellular eukaryotes and classified as protista. Rhizaria include species like cercozoa, foraminifera and radiolaria.
<u>Some of the attributes of Rhizaria are:</u>
- non-photosynthethic in nature, but some have a symbiotic relationship with unicellular algae.
- express only rDNA sequences so they can vary in different forms.
- do not have clear morphological characters
- they mostly includes amoebas which functions for food engulfing and help to direct movement in rhizarian protista.
<u>Contribution of Rhizaria to the ecosystem:</u>
- There are known as abundant bacterial grazers, and play very important role in microbial food webs.
- They provide a wide diversity of marine organisms.
- important contributors to oceanic carbon pools .
Hence, Rhizaria are important part of ecosystem.
Answer:
Unicellular organisms may stay as one cell but they grow too. Multicellular organisms add more and more cells to form more tissues and organs as they grow. ... Growth is the increase in size and mass of that organism. Development involves the transformation of the organism as it goes through the growth process.
Explanation:
Yes they can
