Since Dr. Rodriguez thinks her drug, the "New Hair" would work better than "rogaine", the result of the experiment should be "more men in Group C would grow hair over their head than the amount of men in Group B would". Therefor the whole hypothesis would be: If "New Hair" work better than "Rogaine", more men in Group C would grow hair over their head than the amount of men in Group B would.

timurjin [86]

Answer:

Explanation:

Meiosis is a cell division that results from sexual reproduction where half the chromosome of each parent cell contribute its genetic make up resulting in four haploid, genetically different gamete, cells. These are sex cells that determines the gender of a baby.

As part of this process DNA replication first occurs, followed by the two cell divisions, meiosis I and meiosis II, giving rise to four haploid daughter cells different from their parent cells.

1. . For example, lake trout are native to the Great Lakes, but are considered to be an invasive species in Yellowstone Lake in Wyoming because they compete with native cutthroat trout for habitat.

2. Japan

3. Kudzu was introduced from Japan to the United States at the Philadelphia Centennial Exposition in 1876 as an ornamental and a forage crop plant. The Civilian Conservation Corps and southern farmers planted kudzu to reduce soil erosion.

4. Kudzu grows out of control quickly, spreading through runners (stems that root at the tip when in contact with moist soil), rhizomes and by vines that root at the nodes to form new plants. Once established, kudzu grows at a rate of one foot per day with mature vines as long as 100 feet.

5. Pythons compete with native wildlife for food, which includes mammals, birds, and other reptiles. Severe mammal declines in Everglades National Park have been linked to Burmese pythons. ... Raccoons and opossums often forage for food near the water's edge, which is a habitat frequented by pythons in search of prey.

After seeing how few units of energy there is for the trophic levels above. Why are there usually so few organisms at the top le
Vikentia [17]

Energy declines as one climbs up the food chain because energy is wasted as metabolic heat when animals from one trophic level are devoured by species from the next. This causes the presence of only a few organisms at the top level of energy pyramid.

<h3>What is ecological pyramid?</h3>

A graphical representation of the biomass at each trophic level in the given environment is known as an ecological pyramid.

Energy declines as one climbs up the food chain because energy is wasted as metabolic heat when animals from one trophic level are devoured by species from the next.

Thus, this causes the presence of only a few organisms at the top level of energy pyramid.

Dmitriy789 [7]
Yes an offspring can have traits that neither parents have. People have both dominant and recessive genes that control the traits that they have. So the child would have gotten two recessive genes that the parents carry, to display a trait that the parents don’t display.
