The wood thrush makes its nest in woodlands in the northern and eastern United States. As patches of woods become smaller, incre

asing numbers of wood thrush nests have eggs laid in them by the brown-headed cowbird. Cowbirds live in open fields and are nest parasites; the female cowbird flies up to an unattended nest, quickly lays an egg in it, and leaves the host parents to raise their "adopted" young. Wood thrushes are decreasing in numbers because ________.A) habitat fragmentation makes it easier for cowbird parasitism to occurB) cowbirds are an invasive species that is rapidly increasingC) climate change is reducing nest site availabilityD) overharvesting in the open fields has driven the cowbirds into the woodlandsE) pollution of the open fields has caused a change in cowbird behavior

Answer:

A) habitat fragmentation makes it easier for cowbird parasitism to occur

Explanation:

Habitat fragmantation is the separation of a landscape into various land uses (e.g for development, agriculture, etc), resulting in numerous small, disjuunct habitat patches left for use by wildlife.

As the name implies, it describes the emergence of discontinuities(fragmentation) in an organism's preferred environment (habitat).

Fragmentation eliminates habitat for those species requiring large unbroken blocks of habitat

This disconnection of natural habitat amplifies the negative effects of decreasing total habitat area.

As patches of woods become smaller, increasing numbers of wood thrush nests have eggs laid in them by the brown-headed cowbird. Cowbirds live in open fields and are nest parasites; the female cowbird flies up to an unattended nest, quickly lays an egg in it, and leaves the host parents to raise their "adopted" young. Wood thrushes are decreasing in numbers because <u> habitat fragmentation makes it easier for cowbird parasitism to occur.</u>

Answer:

A) habitat fragmentation makes it easier for cowbird parasitism to occur

Explanation:

It is a situation where by there is transformation of a large habitat into smaller patches with smaller total area secluded from one another by a habitat different from the initial one.

Habitat fragmentation can be caused due geological processes which distort the physical environment. It is also casued by human activities which could lead to loss or extinction of certain species.

Habitat fragmentation could possibly lead to loss of habitat and biodiversity.

An object was measured by a worker as
tensa zangetsu [6.8K]

Answer:

2.5271%

Explanation:

The percent error is defined as;

(error/actual value) * 100%

In this case the error will be;

27.7cm - 27.0cm = 0.7cm

The actual value is 27.7cm since it is the one specified by the manufacturer.

The percent error in the worker's measurement is thus;

(0.7cm/27.7cm) * 100 = 2.5271%

The answer is eukarya. While Eukarya, Archaea, and Eubacteria may share some similarities, the most distinctive feature of eukarya is the presence of a membrane-bound nucleus containing the cell's genetic information.

wariber [46]

Answer:

A null hypothesis would be that caffeine doesn't stimulates sunflower plants to grow taller.

Explanation:

Null hypothesis: In research methods, the term "null hypothesis" is described as a type of hypothesis that proposes that there's no difference between specific characteristics of a particular data gathering process or population.

Function: The main aim of "null hypothesis" is to prove whether or not a specific test or study is supported and is separated from the researcher's own decisions and values. It is responsible for providing a way to a given study or test and is represented by H0.
