A high rise condominium is planned for a barrier island that lies off the southwest coast of Florida. Which of these predictions

could be made about the impact this construction will have on the sustainability of the coastal ecosystems?
Group of answer choices

Predators will abandon the habitat as humans are the top predator in any ecosystem.

The ecosystem will be destabilized as abiotic resources like available space are reduced.

The costal ecosystem populations will decline until new species evolve that are adapted to live new humans.

Key species found on the barrier island will move to a new habitat.

Answer:

The ecosystem will be destabilized as abiotic resources like available space are reduced.

Key species found on the barrier island will move to a new habitat.

Explanation:

Due to living of humans on the barrier Island with adversely affected the organisms present on that Island because the loss of habitat occur due to living of humans and the important species migrated to other habitats where no humans are present. So this action greatly change the environment of barrier Island and the ecosystem will be destabilized.

Answer:

C. Beak size is an inherited trait in the finch population under study.

D. Birds that could eat larger, tougher seeds survived and reproduced during the drought.

E. Beak size varies among the birds in the finch population under study.

Explanation:

The presence of genetic variations among the individuals of a population is required for natural selection to be operative. Natural selection targets the beneficial genetic variations present in the population. Natural selection refers to the differential reproductive and survival success of organisms of a population due to some beneficial genetic traits. These organisms with beneficial genetic traits are able to survive and leave more progeny under prevailing conditions.

If the natural selection has occurred in the ground finch population for the beak size, the beak size should be a genetic trait since natural selection works on genetic traits only. The finch population should have variations with respect to the beak size. The finches having the larger beak size that enabled them to feed on larger, tougher seeds should have higher survival and reproductive fitness during the drought.

Under these conditions, natural selection would favor the finches with larger beak size and would eventually result in an increase in the average beak size of the future generations.

Motor (efferent) neurons carry information _____ the brain whereas sensory (afferent) neurons carry information ______ the brain
Norma-Jean [14]
Neurons are the building blocks of the nervous system. They are the links so that information could be processed as electrochemical signals. There are three fundamental kinds of neurons in our body:

1. Motor neurons - they carry signals from the central nervous system (CNS) to the body parts such as muscle movement
2. Sensory neurons -  they carry signals from other body parts to the CNS
3. Interneurons - interlinking neurons between the brain and the spinal cord

Thus, the correct and complete statement above should be

<span><em>Motor (efferent) neurons carry information </em><em>from </em><em>the brain whereas sensory (afferent) neurons carry information</em><em> to</em><em> the brain.</em></span>

Answer:

Percent error = 8.3%

Explanation:

Given data:

Accepted value of specific gravity = 7.2

Measured value of specific gravity =  7.8

Percent error = ?

Solution:

Percent error = measured value - accepted value / accepted value × 100

Now we will put the values in formula.

Percent error = 7.8 - 7.2/7.2 × 100

Percent error = 0.6/7.2 × 100

Percent error = 0.083 × 100

Percent error = 8.3%
