A group of students did a experiment to test how temperature affect the rate of photosynthesis in an Elodea plant they increased and decrease the temperature each plant was exposed to and then measure the number of oxygen bubbles that were produced the graph below shows the results of the experiment according to the graph which of the following statements is correct? A) as temperature increases the rate of photosynthesis constantly increases.

B) as temperature increases the rate of cellular respiration constantly increases.

C) The rate of photosynthesis increases with temperature up to 30°C and then decreases.

D) The rate of cellular respiration increases with temperature up to 30°C and then decreases.

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression.c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression.d-neelaredoxin is only produced when there is exposure to o2 or h2o2.

Most animal cell membranes have proteins that pump. ions out of the cell and potassium ions into this

During a fierce storm a large number of tall trees on an island are uprooted by the wind and die. most of the trees on the island are now short trees and produce seeds that grow into short trees. what concept is shown in this example? question 5 options: natural selection artificial selection genetic engineering gene splicing
