Quaking Aspen (Populus tremuloides) reproduce via rhizomes, creating immense colonies that may include thousands of trees. One c

olony in Utah, nicknamed Pando, consists of a grove of ~47,000 trunks. Despite their massive size, scientists worry that these stands are vulnerable–why?

Answer:

These strands are clones, however, due to their low genetic variability, the population becomes susceptible to diseases taking place in plants. Pando comprises grove of about 47000 trunks, these all are genetically similar that develops from a solitary underground species, Quaking aspen tree. Pando is an extremely large clone.  

However, for the past some years, scientists are worried about Pando's health. For the past thousands of years, Pando was living in fine tune with the native wildlife population, but for the past some years, a shift in balance is noticed. As in the absence of the development of novel stems, nothing will be able to substitute the natural withering of the older ones, if this goes on, the death of Pando will take place.

How does the speed of flowing water affect its ability to erode <br><br><br> HELP PLZZZ!!!
sergeinik [125]

Answer:

<h3>Moving water also picks up and carries particles of soil and rock. The ability to erode is affected by the velocity, or speed, of the water. ... As water slows, larger particles are deposited. As the water slows even more, smaller particles are deposited.</h3>

What is meant by a phenotype ratio in a Punnett square? (1 point)
Lemur [1.5K]

Given the nature of a punnet square, we can conclude that the ratio in question refers to the combination of genotypes present in the square.

A punnet square is a diagram used to attempt to predict the <u>genetic composition </u>for the <u>offspring</u> of certain parents, that is the genotype for this specific cross. This is done by creating a square in the form of a grid and placing the genotypes of the parents on the outside of this then crossing them along the inside.

This diagram provides us with the probability of each genotype outcome. This is known as the phenotype ratio. The phenotypic ratio is the amount of times a specific outcome, such as a certain pair of alleles appears in the predicted genotypes of any of the <u>offspring pertaining </u>to this <u>cross</u>.

Why would be expect there to be fewer foxes than caterpillars in this ecosystem?
iren2701 [21]
Foxes eat a variety of animals, which includes caterpillars. On the contrary, most caterpillars eat only plants. In any ecosystem, you always have a larger number of plants than the number of animals which eat plants, and you have an even smaller number of animals which eat other animals. That is related to the flow of energy in the ecosystem:
1) The sun provides solar energy and plants use part of it for photosyntesis. Later, that energy will be stored by the plant as chemical energy.
2) Herbivore animals eat some of the plants, in order to use their chemical energy. Animals can never eat all plants because that would lead to extinction. Besides, part of the chemical energy of the plants they have eaten is wasted because it converts into heat energy.
3) Carnivore animals eat herbivore animals. Same conclusion, they can never eat all herbivore animals and they cannot use all their energy. If they are ominvore, they are sort of sharing the plants with herbivores, so herbivores can eat less plants.
Malnutrition reduces the population, so less food leads to smaller population.
