Answer:
The Hardy-Weinberg law states that in a sufficiently large population, in which matings occur randomly and that is not subject to mutation, selection or migration, gene and genotypic free frequencies are kept constant from one generation to another, once a state of equilibrium has been reached, which in autosomal loci is reached after one generation.
It is said that a population is in equilibrium when the alleles of the polymorphic systems maintain their frequency in the population throughout the generations.
Answer:
Hey there!
A population increase follows a period of scarcity.
With more people, the food and water resources get scarce, and isn't always enough for everyone.
Let me know if this helps :)
Answer:
have curved protofilaments at their plus ends
Explanation:
Microtubules are polymers of tubulin proteins that function as the cytoskeleton of eukaryotic cells. Microtubules are dynamic structures that can grow and shrink at a rapid rate. During this process, tubulin subunits can associate and dissociate at the plus end of the protofilament. Tubulin subunits bind to two GTP molecules, one of which is hydrolyzed to GDP after assembly. When microtubules are unstable, protofilaments curl outwards because GDP-bound tubulin has a weak affinity (thereby curving it) and disassemble. The dynamic stability of microtubules is regulated by a feedback loop: when microtubules shrink, free tubulin concentration increases and microtubules start to grow. As microtubules grow, free tubulin concentration decreases and the rate of GTP-tubulin addition also decreases.
Hello. This question is incomplete. The full question is:
"Scientists are testing the effect of different scrubber technologies on the removal of pollutants from coal power plants. The scrubbers use a slurry of limestone and water. Which of the following best describes the impact of modifying the slurry by increasing the amount of limestone? The amount of sulfur dioxide released will decrease. A The amount of ground-level ozone released will decrease. B The amount of water released will increase. C The amount of carbon monoxide released will increase.
"
Answer:
The amount of sulfur dioxide released will decrease.
Explanation:
As you may already know, coal is a fossil fuel and burning it releases many toxic gases into the atmosphere, including sulfur dioxide.
A suspension of water and limestone, allows the calcium present in limestone to enter into reaction with sulfur dioxide, forming calcium sulfide and decreasing the emission of sulfur in the atmosphere.
The greater the amount of limestone in this suspension, the less sulfur dioxide will be released into the environment.
Answer:
Rice, Corn and Bamboo
Explanation:
Parallel venation is a kind of venation in which the veins runs parallel to the to the length of the leaves from its base of the leaf to the apex of the leaf or the tip of the leaf.
It is a characteristics of many monocot plants.
Few example of plants having parallel venation are grasses, bamboo, rice, corns, banana, musa, canna, etc.
