All of them. Air because in helps make food it also lets the plant breath. Water because it helps move nutrients into the plant. Soil because plants can’t grow without soil.
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.
Answer:
Terrabacteria
Explanation:They have round cells, called cocci (singular coccus), or rod-like forms (bacillus). Many Firmicutes produce endospores, which are resistant to desiccation and can survive extreme conditions.
Answer:
Algae
Explanation:
Algae are found in large groups and are diverse. They are plant-like organisms as well.
A <u>Scientific method </u>is a series of steps used to determine solutions based on needs and wants.
<h3>What is needs assessment?</h3>
A needs assessment is a process that bridges the gap between an organization's current state and the desired conditions. It is a systematic procedure for identifying and addressing performance gaps as well as repairing any defects that may occur in an organization.
<h3>What are the six steps of the scientific method?</h3>
- Describe the issue :Observation with intent
- research : learn more about the subject
- educated guess : hypothesis forecast the outcome of the problem
- experiment :Create a procedure for testing the hypothesis.
- analyze :Keep track of the experiment's outcomes.
- conclusion : compare the hypothesis to the results of the experiment
<h3>What are the Characteristic Features of Scientific Methods?</h3>
- Students learn to identify and formulate scientific problems correctly and in an organized manner using scientific methods.
- Students are trained in information processing techniques using scientific methods.
- Scientific methods help students develop the ability to think critically and rationally, allowing them to make decisions on logical and rational grounds.
