Answer:

I think its invasive species compete for resources with native species.

Explanation:

Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. The invasive species may provide little to no food value for wildlife. Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife.

Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

Appears to contain a multilobed nucleus. what is the most likely identity of the observed leukocyte?
Brrunno [24]

Neutrophil is the most likely identity of the observed leukocyte

<h3>What is Neutrophil ?</h3>

The most common type of granulocyte in humans are neutrophils, also known as neutrocytes or heterophils, which make up between 40% and 70% of all white blood cells. They are an essential part of the innate immune system, and they have different functions depending on the species.

The bone marrow-produced stem cells are differentiated into the neutrophil-killer and neutrophil-cager subpopulations. Due to their potential ability to access tissues that other cells or substances cannot, they have a limited lifespan and are very migratory. There are two different types of neutrophils: banded and segmented neutrophils (or bands). They belong to the same family of cells as basophils and eosinophils, which is known as PMNs.

It is estimated that animal- or insect-pollinated plants produce 1000 pollen grains for each ovule; wind-pollinated plants produ
Ede4ka [16]

Explanation:

The plants which use animal or insects as pollination vector produce less pollen compared to the wind-pollinated plants.

This could be due to the reason that the chances of pollination by wind are less than the pollination by the animal or vectors.

The chances of pollination in animal pollination are high as the animals to feed on the useful product of plant will go to the other plants but in wind pollination, the chances are less as it depends on the speed and direction of the wind.

Thus, wind-pollinated plants produce high number of pollens.
