Answer:
As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant.
Answer:
A) 48
B) 96
C) 48
D) 48
Explanation:
Attached is a table summarizing the number of chromosomes and chromatids in the different stages of mitosis and meiosis in humans who are described as 2n = 46.
For the organism which is described as 2n = 48, substitute 46 in the table for 48 to get the appropriate figures.
The two cells of the similar shape, and size have different levels of the ongoing metabolic activity. On one hand, the cell a is metabolically quiet, which means that no energy consuming chemical reactions are taking place in this cell. On the other hand, the cell b is actively consuming the surrounding oxygen. In this scenario, the oxygen will more quickly diffuse into the cell b because the diffusion gradient for oxygen in this cell is steeper than in the cell a.
Hence, the blanks can be filled with 'b and the diffusion gradient is steeper' respectively.
Answer:
D. It is a process of change during which species in a community are established or replaced
Explanation:
Ecological succession is a process that occurs when a community is being established or replaced.
It shows the change in community over time, focusing on the types of plants and the maturity of plants that are in the community.
Primary and secondary succession are the two types of succession. Primary succession shows the process of change in the establishment of a community. Secondary succession shows the change when a community is being replaced.
So, the correct answer is D. It is a process of change during which species in a community are established or replaced
Answer:
The function of segregating the interior of the cell enclosure to the outside is known to occur by the function of the plasma membrane. These molecules comprising the plasma membrane is none other than lipids. Highly enriched hydrophobic tails of lipids interact with other lipids in a typical bilayer arrangement to regulate and control gene expressive Molecular and other crucial ions from moving in.
