The correct answer is: D. Primary succession occurs in a habitat that has never been colonized by any species before.
Ecological succession can be defined as ae process of change in the species structure of an ecological community over time. There are two types of succession:
• Primary succession- begins in new habitats, uninfluenced by pre-existing communities
• Secondary succession –formed after a disruption of a pre-existing community.
The best explanation for the the early hominid that indicated most of her body weight was above her pelvis is that her apelike structures indicates she could use tools like a chimpanzee. Scientists call her the Handy Human. The correct answer is C.
<h2>Correct answer is option "A"</h2>
Explanation:
- The initial concentration of the substrate(Keeping the initial substrate concentration steady permits the specialist to think about the response rates under various natural conditions. The response rates will furnish the scientist with data about the protein's capacity in various situations).
- A substrate is a substance that is used to make a final product. It is changed and reformed during the process. Sometimes chemical groups are added or taken away.
- In the cell, enzymes bind and change substrates into their final product. When the enzyme is bound to the substrate, it is known as an enzyme-substrate complex.
- Substrate concentration is the amount of substrate present that can be turned into a product. The unit of measurement usually assigned to eggs is dozen. Substrate concentration can be measured in various ways. Since the substrates inside the cell are suspended in cellular fluid, the substrate concentration is most commonly measured in molar concentration, or molarity (M), which is moles per liter.
- Hence,the correct answer is option A "the initial concentration of the substrate.
A Eukaryote is more complex. It has a nucleus whereas the Prokaryote does not.
<h2><u>Answer:</u></h2>
It is called the plasma membrane. An infinitesimal film of lipids and proteins which shapes the outside limit of the cytoplasm of a cell or encases a vacuole, and controls the entry of atoms all through the cytoplasm.
The essential capacity of the plasma layer is to shield the cell from its environment. Made out of a phospholipid bilayer with implanted proteins, the plasma film is specifically penetrable to particles and natural atoms and manages the development of substances all through cells.
