1 answer:

3 0

DNA is a group of nucleotides that are linked together. The hydrogen bonds are responsible in making the double helix structure stable. The two strands of DNA are linked and stays in a stable shape because of the hydrogen bonds located between adenosine and thymine base pairs. Three hydrogen bonds are between cytosine and guanine.

Answer of layla, age 4, breaks out in hives whenever she has eaten too many strawberries or oranges. she will occasionally accep

Artemon [7]

Strawberries and oranges are high in Vitamin C (in fact, a cup of strawberries has more Vitamin C than a medium-sized orange) as well as potassium. We can thus infer that Layla is probably deficient in these nutrients. To supplement Layla's intake of Vitamin C, Ruby can serve red and green peppers and kiwi, which (like strawberries) have more Vitamin C than an orange. To supplement Layla's potassium intake, Ruby can serve spinach, broccoli, and cantaloupe.

The taiga biome is sometimes called a coniferous forest. This is because it is home to many coniferous trees such as pine, spruce, fir, and hemlock.

Taiga biomes are found between 50 and 60 degrees north latitudes. The taiga is the largest land biome on Earth, covering over 15 percent of the Earth's land. A large area of taiga is located in the northernmost forests across Europe, Asia, and North America. The taiga generally has two seasons. The summers are short, moist, and warm. The winters are long, cold, and dry. Most precipitation is in the form of snow, though rain does occur during the summer. Most animals in the tundra hibernate or migrate during the winter. Hawks, bears, foxes, wolves, deer, bats, and chipmunks can be found in the taiga.

Bacteria are prokaryotes, fungi and protists are eukaryotic organisms and viruses are not living.

<h3>In what ways it is possible to distinguish prokaryotes from eukaryotes?</h3>

Bacteria (e.g., E coli) are prokaryotic organisms whose cells don't have nuclei or membrane bound organelles, reproduce by asexual ways such as binary fission, and they are beneficial as descomposers.

Some common diseases caused by bacteria include tetanus (Clostridium tetani), pneumonia (Klebsiella pneumoniae), cholera (Vibrio cholerae), etc.

Moreover, protists (e.g. algae) and Fungi (e.g. Saccharomyces cerevisiae) are eukaryotic organisms that have cell nuclei and organelles, can reproduce by asexual reproduction, can perform photosynthesis (algae) or acts as decomposers (fungi).

Some common diseases caused by protists/protozoans include malaria (Plasmodium), sleeping sickness (Trypanosoma), etc.

Some common diseases caused by fungi include aspergillosis (Aspergillus), candidiasis (Candida albicans), etc.

Finally, viruses are not living because they need a host to survive and are also useful as vectors to design gene therapy techniques.

Some common diseases caused by viruses include AIDS (HIV retrovirus), dengue fever (Flaviviridae viruses), etc.

Bacteria are used to produce insulin and other natural medications, viruses are used as carriers for the treatment of diseases, protozoans can enhance the fertility of soils and fungi are employed in the preparation of foods.

In conclusion, bacteria are prokaryotes, fungi and protists are eukaryotic organisms and viruses are not living.

What causes humans to become lactic acid fermenters?

ANEK [815]

Cells resort to lactic fermentation if there is no available oxygen, and so they cannot carry out the ETC (or the Krebs Cycle). This can happen when running, if not enough oxygen is being taken in, where muscle cells will use lactic acid fermentation.
