Nucleic acids refer to DNA and RNA. In eukaryotic cells, the majority of DNA is found in the nucleus, with a small amount of mitochondrial DNA in the mitochondria.
Answer:
A. anaerobic respiration in muscle cells, forming lactic acid
Explanation:
Running marathon is a vigorous exercise, which often leads to excessive use of oxygen in the cells of the athlete. This causes the cells to switch from the aerobic (with oxygen) to the anaerobic (without oxygen) mode of respiration. This anaerobic respiration produces a product called LACTATE OR LACTIC ACID.
The lactic acid becomes excessive and gets stored in the muscle cells of the athlete. This often leads to cramps, muscle pulls etc. during the marathon. Therefore, an individual running a marathon may experience periods of oxygen deprivation that can lead to anaerobic respiration in muscle cells, forming lactic acid.
Answer:
This is issued when a tornado is indicated by the WSR-88D radar or sighted by spotters; therefore, people in the affected area should seek safe shelter immediately. They can be issued without a Tornado Watch being already in effect. They are usually issued for a duration of around 30 minutes.
A Tornado Warning is issued by your local National Weather Service office (NWFO), see map below. It will include where the tornado was located and what towns will be in its path. If the tornado will affect the nearshore or coastal waters, it will be issued as the combined product--Tornado Warning and Special Marine Warning. If the thunderstorm which is causing the tornado is also producing torrential rains, this warning may also be combined with a Flash Flood Warning. If there is an ampersand (&) symbol at the bottom of the warning, it indicates that the warning was issued as a result of a severe weather report.
After it has been issued, the affected NWFO will followed it up periodically with Severe Weather Statements. These statements will contain updated information on the tornado and they will also let the public know when warning is no longer in effect.
Explanation:
Divergence of crustal plates. I could be wrong though and if I am my bad :))
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.
