Heart rate increases in a linear fashion to increases in the intensity of exercise. This is illustrated in the adjacent graph, showing how the heart rate (in beats per minute – bpm) increases to match the incremental demands of walking, jogging and running.
Explanation:
Greenhouse effect, a warming of Earth's surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour , carbon dioxide, methane, and certain other gases in the air. Of those gases, known as greenhouse gases, water vapour has the largest effect.
<h3><u>Answer;</u></h3>
C) The binding of substrate changes the conformation of the active site to bind substrate more tightly.
<h3><u>Explanation;</u></h3>
- Induced fit theory is the idea that the substrate plays a role in determining the final shape of the enzyme and that the enzyme is partially flexible. Other molecules may be too small to induce the proper alignment and therefore cannot react.
- Only the proper substrate is capable of inducing the proper alignment of the active site.
- Induced fit model asserts that when the active site on the enzymes makes contact with the proper substrate, the enzyme molds itself to the shape of the molecule.
Phylogenetic trees always show increased branching, representing increased diversity over time.
Explanation:
A new branch in phylogenetic trees appears when new species appear, meaning that diversity increases. The appearing of new branches can show speciation processes and it can also help to understand how a certain lineage evolved through time or the specific divergence in one point.
Answer:
Genetic drift is referred to the changes in allele frequency in a gene pool. Gene flow is the process of alleles moving from one population to another.
