Answer:
the model failed to account for the changes in the appearance of the inferior plants.
Explanation:
The model was a geocentric model that was based on the refraction. Though the theory was sound it did not provide a full truth about the orientation of planets in space. Also, the theory lacked compelling evidence of the heliocentric hypotheses. in addition, the model was rejected based on the fact that earth rotation cannot be immediately felt. In addition, earth does not have a perfect circular path around the sun. Lastly, the geocentric model makes much sense.
If a nutrient is short in supply, it will limit the organisms growth.
Answer:
<h2>b) 640,000</h2>
Explanation:
Given:
Initial population = 10,000
Doubling time= 20 minutes
total culture allowed time = 2 hours
after 2 hours final bacterial population is 640,000
calculation:
10,000 doubles after 20 minutes = 20,000 and so on... final population after 2 hours = 640,000.
Answer: d. Extracellular matrix was discovered more than 20 years ago.
Explanation:
According to biological sciences, the extracellular matrix is a matrix that consists of three dimensional network of extracellular macromolecules such as enzymes, collagen and glycoproteins which provide structural and biological support for surrounding cells as well.
It is found that it is discovered over 20 years ago in the matrix formed in the mouse EHS sarcoma. Therefore, correct answer is (d).
