Many of the plants in a grassland environment are specifically adapted to that habitat. The natural selection that led to this a

daptation was a result of all
the following EXCEPT
populations of plants naturally exhibit variation
plants produce more offspring than can survive.
the available resources do not support all the plants,
related plant species share some genetic material.

Answer: hybridisation between related species is unlikely to contribute to adaptive speciation.

Explanation: any population has natural genetic variation. The available resources are insufficient for all plants (and conversely, not all offspring survive). Natural selection favours variations better suited to the conditions.

Although hybridisation is more common in plants than animals, and can lead to speciation, adaptive radiation from an ancestral species is the general response to environmental change, such as from rainforest to savanna. There is low probability of selective advantage from hybridisation of two ancestral species adapted to niches within the original habitat when the conditions in those niches changes significantly.

Normally, how many chromosomes are required to determine the outward expression of a trait?a homologous paironly oneany twotwo p
jeka94

Answer:

A homologous pair

Explanation:

In determining the expression trait of humans, this is based on the homologous chromosomes. This in turn comprised of alleles otherwise known as homologous alleles. The homologous loci are thereby located in these alleles which served as the formation of traits when combined.

Hence, normally, A HOMOLOGOUS PAIR is required to determine the outward expression of a trait?

insens350 [35]

Answer:

The correct answer is - option 3.

Explanation:

The given options are the question are affects the protection of the ecological system in one or another manner but the mandating the rights of government sale of the logging rights in a national forest must be a proper and fair market value.

This will lead to a decrease in the illegal sale of logging sale which results in maintaining the ecological system in the national forest.

Thus, the correct answer is - option 3.

How do magnetic stripes of iron in ocean rock provide evidence of seafloor spreading
STatiana [176]

Answer:

In the 1960s, scientists found evidence that new material is indeed erupting along mid-ocean ridges. The scientists dived to the ocean floor in Alvin, a small submarine built to withstand the crushing pressures four kilometers down in the ocean. In a ridge’s central valley, Alvin’s crew found strange rocks shaped like pillows or like toothpaste squeezed from a tube. Such rocks form only when molten material hardens quickly after erupting under water. These rocks showed that molten material has erupted again and again along the mid-ocean ridge.

When scientists studied patterns in the rocks of the ocean floor, they found more support for sea-floor spreading. You read earlier that Earth behaves like a giant magnet, with a north pole and a south pole. Surprisingly, Earth’s magnetic poles have reversed themselves many times during Earth’s history. The last reversal happened 780,000 years ago. If the magnetic poles suddenly reversed themselves today, you would find that your compass needle points south.

Explanation:

I found this somewhere.

What best explains why there's fewer secondary consumers than producers?
monitta

Answer:

because of inefficiency

Explanation:

The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. ... Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.
