The addition of dynactin caused dynein to travel farther along the micro tubule.
<u>Explanation:</u>
Dynein is a family of cytoskeletal motor proteins that move along micro tubules in cells. They convert the chemical energy stored in ATP to mechanical work. Dynein transports various cellular cargo, provides forces and displacements important in mitosis, and drives the beat of eukaryotic cilia and flagella.
Dynactin is a 23 sub unit protein complex that acts as a co-factor for the micro tubule motor cytoplasmic dynein-1. It is built around a short filament of actin related protein-1.
Answer:
Fossil record is used to study macro evolution.
Explanation:
Macroevolution may be defined as the change above the species level. Fossils are the impressions of dead plants and animals buried under the surface of rocks.
Fossils provide the direct evidence of macroevolution. For example : Paleozoic era was dominated by trilobites, crinoids and brachiopods. Rocks that one part of paleozoic era are now contains the fossils of trilobites, crinoids and brachiopods. These species may either extinct or not common in today's world. Thus, fossil record can be used to study macroevolution.
When a substance becomes part of a mixture, its chemical properties ONLY change if the resulting mixture is homogeneous. Otherwise nothing happens to the properties.
Explanation:
The formula of a selected pure substance doesn't amendment simply because it becomes a part of a mix. Chemical properties can amendment in a very mixture. If you've got a mix of water and alcohol, the melting point are below 0C. That doesn't mean that water now not freezes at 0C, it simply means that the mixture of water and alcohol doesn't freeze at 0C.
The available amount of food is what is going to determine the carrying capacity. Also, carrying capacity can be dependent on the amount of shelter a system has.
Answer:
Because each strand acts as a template for the synthesis of a new, complementary strand.
Explanation:
This is known as semiconservative DNA replication. Leading and lagging strands are complementary, antiparallel strands (one is 3'-5' while other is 5'-3- direction) which are replicated differently. The leading strand is replicated continuously while the lagging strand is replicated in fragments-Okazaki fragments. Replication of both strands is performed by DNA polymerase.
