One concern that arises from building a dam is that fish are not able to migrate. One way that fish can gain passage to their destinations is by _____
a. fish ladders
b.fish trucks
c.fish boxes
d.fish escalators

Answers

Answer 1

Answer:

The correct answer is option A. Fish ladders

Explanation:

Fish ladders are a stair-like structure that gives the passage to the migrating fish to get around a dam  to their destinations. As dams are an obstruction to fishes like salmon that migrate in the river upstream to breed, fish ladders have been created to allow the fish to get to their destinations by providing a passage around the dam.

Thus, the correct answer is option A. Fish ladder.

Answer 2

The correct answer is A. Fish ladders.

Explanation

A fish ladder is the name given to the canal or structure found some reservoirs or dams, that connects it with the current of the river. These systems were created to prevent fish from being trapped in the reservoirs and therefore, prevents fish are unable to find their food and live in the rivers. Additionally, fish ladders are the main way to guarantee fish can migrate to other places which is essential for natural biological processes such as reproduction. So, the correct answer is A. Fish ladders.

Which structure(s) on the neuron in model 1 would receive a signal from either a sensory cell (taste bud, touch receptor, retinal cell) or from another neuron?

Answers

Final answer:

Dendrites with free nerve endings or encapsulated endings, as well as specialized receptor cells, are the neuron structures that would receive signals from sensory cells or other neurons.

Explanation:

In model 1 of the neuron, the structures that would receive a signal from either a sensory cell such as a taste bud, touch receptor, retinal cell, or from another neuron are dendrites with free nerve endings or encapsulated endings, as well as specialized receptor cells. Neurons with free nerve endings are found, for example, in the dermis of the skin and are responsible for sensing pain and temperature. Neurons with encapsulated endings like lamellated corpuscles respond to pressure and touch.

Additionally, specialized receptor cells like photoreceptors in the retina of the eye specifically respond to light stimuli. These cells, after receiving the stimuli, release neurotransmitters onto other cells, such as bipolar cells, which then synapse with neurons like the optic nerve. Therefore, these neuron structures are key for the transduction of sensory stimuli into neural signals that can be processed by the nervous system.

All the catfish that live in the pond behind Serge's house make up a ___________ of catfish.
A) community
B) family
C) habitat
D) population

Answers

A . community
Multiple are a community

Final answer:

The group of catfish living in Serge's pond is a population, which is a group of the same species living and interacting in the same area. A community includes different species in the same area.

Explanation:

The group of catfish living in the pond behind Serge's house make up a population of catfish. A population consists of all the individual organisms of the same species that live and interact in the same area. As such, the correct answer to the question is option D - population. This means that all of the catfish, being the same species living in the pond, are considered a single population.

A community, on the other hand, would consist of all the populations of different species that live in the same area. For instance, the community in Serge's pond would include not just the catfish, but also any other fish, plants, insects, and other organisms living in or around the pond.

Of the molecules sif4 and sibr4, which has bonds that are more polar

Answers

Of SiF4 and SiBr4, the atom SiF4 is more polar. This is because the cation of both molecules are Silicon, but the anions of each are different. In SiF4, the anion is Fluorine, which is more electronegative than the Bromine in SiBr4, which creates a larger dipole, which results in a more polar molecule.

In some cancer, cells reproduce uncontrollably and form masses called tumors. what processes are not taking place that allow for this to occur

Answers

The processes that are not taking place which allow for tumors to form is that the cancer cells are not responding to the signals that regulate the growth of cells. Living cells use cell division to reproduce and to repair damages;  cell division is tightly controlled by the body system. When cells stop responding to the regulating signals, tumors will be formed.

What is Locus?

A locus in genomics refers to a physical spot or location inside a genome (such as a gene or another DNA section of interest). Locus is pluralized as loci.

We use the term locus to describe the location of a gene on a chromosome. So, the actual placement of a gene on a chromosome is what matters.

It serves to specify the gene's surrounding area. A portion of the chromosome would be the city if you thought of the complete chromosome as the nation where the gene is situated. This exact neighborhood where the gene is located is the more specialized area, or the locus.

How does the population growth rate affect how long Earth's coal supply will last?
A. The coal supply lasts the longest when the population growth rate is high.
B. The coal supply is used up the slowest when the population growth rate is average.
C. The coal supply is used up the fastest when there is low population growth.
D. The coal supply lasts the longest when there is no population growth.

Answers

D is the best answer! (If you mean population growth as in humans)

The correct answer is option D.The coal supply lasts the longest when there is no population growth.

As we know that coal reserves are non renewable resources. The formation of coal reserves took million of years. So once they are used up they will never ever be available again. The more is the population, the more will be the requirement of energy resources like coal reserves to sustain such large population. So, high population will tend to use more and more coal to meet daily energy requirement. But if there is no population growth, that time only existing population which is fixed & comparatively less will use the coal resources and therefore, the coal supply will last for a longer time.
