Extinction to different animal species, could vause forest fires and destroy animal habotats therefor becoming extinct, could over heat water causing algae to form on the top not letting sunlight through for plants to photosynthesize which doesnt give fish the nutrients they need to survive.
Answer:
A biologist discovered a young, four-legged animal. The animal had lungs, seemed to fertilize internally, and its outer surface was covered with scales. In which class of animals is the biologist likely to place the animal?
reptile
Answer:
The events in chronological order are:
- Abrin is absorbed into the blood and enters the body's cells
- Abrin binds to ribosomes in the cytoplasm
- Abrin inactivates the 28S rRNA in the large subunit of the ribosome.
- Ribosomes are unable to add new amino acids to polypeptides
- Protein synthesis halts in many tissues
- Multiple organ systems fail
- Victim dies
Explanation:
Abrin is a toxic protein obtained from the seeds of Abrus precatorius, it is highly toxic, with an estimated human fatal dose of 0.1-1 microgram/kg, and causes death after accidental and intentional poisoning.
When ingested the abrin would enter the victim's body and travel through the blood and eventually enter a cell's cytoplasm (abrin is absorbed into the blood and enters the body's cells). Once there it would interact with the ribosomes and reacts with them on a molecular level (peptide bond catalytic enzyme) (abrin binds to ribosomes in the cytoplasm), which results in the ribosome exhibiting its toxic response to abrin (abrin inactivates the 28S rRNA in the large subunit of the ribosome). As a result of the ribosome reacting to abrin (ribosomes are unable to add new amino acids to polypeptides), protein synthesis within that cell is affected (protein synthesis halts in many tissues). Once multiple cells are affected by abrin the organ will exhibit its toxic response (multiple organ systems fail), and the victim would die.
The coenzymes of <u>folate </u>b-vitamin are needed for the synthesis and maintenance of new cells
<h3>What is
b-vitamin?</h3>
B vitamins are a group of water-soluble vitamins that are crucial for red blood cell production and cell metabolism. Despite having names that sound similar (B1, B2, B3, etc.), these vitamins are chemically different substances that frequently coexist in the same foods. Dietary supplements that include all eight are typically referred to as vitamin B complexes. The exact number or name of each vitamin, such as B1 for thiamine, B2 for riboflavin, and B3 for niacin, is used to identify individual B vitamin supplements. Some substances, like pantothenic acid, biotin, and folate, are better known by their names than by their chemical names.
Each B vitamin either functions as a cofactor (usually a coenzyme) for important metabolic processes or functions as a precursor required to produce one.

Firstly sunlight is needed for the chloroplast to get it activated by the photons in solar energy so that light dependent reactions take place. And then the raw materials like minerals,water,sunlight,etc... Are needed for the process photosynthesis.
