Answer:
The correct answer is - negative.
Explanation:
Cl- ion is more concentrated outside of the cell, as it is given 140 and therefore it will try to move to the inside of the given cell as inside ion concentration is low.
At last, the diffusive force will be get to equilibrium due to an electrostatic force pulling Cl- ions back out of the cell. At this equilibrium point, Cl- ions will moved towards to the the neuron and cause the membrane potential to be more negative.

When you breathe, the pressure inside the lungs is different than the pressure outside the lungs. This is an example of a(n) __________. When you breathe, the pressure inside the lungs is different than the pressure outside the lungs. This is an example of a(n) __________. concentration gradient pressure gradient electrical gradient temperature gradient
Answer:
pressure gradient
Explanation:
The correct answer would be pressure gradient.
A pressure gradient is created when there is a difference in the amount of pressure between two points or locations that are adjacent to one another.
In this case, the two locations that are adjacent to one another are the inside and outside of the lung. When one breathes in, the pressure inside the lung is more than that of the outside and the lung expands as a result. When we breathe out, the pressure outside is more than that of the inside and the lung collapses.

Which is an example of temporal isolation?
flowers that bloom in different months
birds that have different mating calls
fruit flies that mate in different locations
squirrels that have different fur colors
Flowers that bloom in different months is an example of temporal isolaton.
What is temporal isolation?Temporal isolation is a type of reproductive isolation that occurs when two or more species reproduce at different times, thereby preventing mating between them. This can happen in a variety of ways, such as when one species is active during the day and the other at night, or when they breed during different seasons.
Temporal isolation can lead to the evolution of new species because it prevents interbreeding between populations that would otherwise exchange genetic material. Over time, these isolated populations can accumulate genetic differences that make it increasingly difficult for them to interbreed, leading to the formation of distinct species that are reproductively isolated from one another.

Until DNA evidence provided evidence to the contrary, flagellated spores were used to group the blastocladiomycetes with the ____.
Answer:
Chytridiomycetes
Explanation:
Blastocladiomycetes were initially grouped under the phylum Chytridiomycetes within the fungi kingdom because the former also have flagellated spores just like the latter
The similarity in spores initially made scientists classify both groups as zoosporic fungi. However, DNA and structural analysis of the spores of the two groups showed that Blastocladiomycetes has no monophyletic relationship with Chytridiomycetes.
Complete the sentence below by selecting the correct words from the drop-down menus. Factors that affect natural selection include , , and .
Answer:
The correct answer is -
variation, over population and adaption.
Explanation:
Natural selection is the process to which the various species and populations are able to adapt and change according the environmental changes. It is affected by three main factors that are variation, over population and adaption.
Variation: varion is one of the factor that pushes the population to change towards the beneficial variation in the population for their survivability and reproducing theirselves.
Overpopulation: over population increases the competition amon population and there fore there resources become limited so few have to change or their ways of utilizing resources.
Adaption: Adapting the change takes place due to any situation in environmental that put stress on the population allow them to adapt according the change or they will extinct.

A. It is a carbonate.
B. It probably formed in a volcanic eruption.
C. It is most likely formed underground.
D. It is extrusive.
Answer: It is most likely formed underground
An igneous rock that has a coarse texture is one that formed from slowly cooling magma deep within the Earth's crust, or from slowly cooling lava on the surface. The slow cooling allows large mineral crystals to grow, giving the rock a coarse, grainy texture.
What can the size and shape determine ?The size and shape of the mineral crystals within the rock can provide information about the rock's cooling history and the conditions under which it formed. Coarse-grained igneous rocks such as granite, gabbro, and diorite typically have crystals that are visible to the open eye, with sizes ranging from a few millimeters to several centimeters in diameter.
The composition of the rock can also be determined based on the types of minerals present in the coarse-grained texture. For example, if the rock contains primarily feldspar and quartz, it is likely a granite. If it contains mainly plagioclase feldspar and pyroxene, it is likely a gabbro.
Overall, the coarse texture of an igneous rock indicates that it cooled slowly over a long period, allowing mineral crystals to grow and form a visible grain structure. The size and composition of the crystals can provide clues about the rock's history and origin.

Describe the change in shape of the lens when a person looks from a near object to a distant object
Answer:
Accommodation is the process of changing the shape of the lens to focus on near or distant objects.
To focus on a near object – the lens becomes thicker, this allows the light rays to refract (bend) more strongly.
To focus on a distant object – the lens is pulled thin, this allows the light rays to refract slightly.

Why do biologists classify
Answer:
Biologists classify organisms because:
Classification allows us to understand diversity better. It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences. It enables us to understand how complex organisms develop from simpler organisms. They are grouped under different categories to understand and study the features, similarities and differences between different living organisms. It is essential to understand the inter-relationships among the different groups of organisms. Classification forms a base for the development of other biological sciences.The perimeter of a rectangle is 16 inches.

The Ames test involves mutants of Salmonella that __________ the ability to make histidine in the __________ of a suspected mutagenic chemical.
Answer:
gain; presence
Explanation:
The Ames test is a lab methodology used to determine whether a particular chemical substance can trigger mutations in an organism, which can be used to indicate whether exposure to the target chemical compound is associated with a greater risk of developing cancer. The Ames test can use a strain of Salmonella typhimurium carrying mutations in a key gene that encodes a protein involved in histidine biosynthesis. In consequence, this S. typhimurium strain is considered to be a 'histidine auxotroph' which is unable to synthesize histidine residues. After exposure to the target chemical compound, bacteria are then cultured in a medium lacking histidine. Subsequently, bacteria that regain the ability to synthesize histidine proliferate to form colonies. Finally, the number of these colonies is then compared with the number of mutants in absence of the potential mutagen, enabling thus the determination of the mutagenic potential of the target chemical compound.

Hantavirus is a relatively rare emerging infectious disease that is spread by contact with the contaminated feces and urine of rodents, such as deer mice. It does not spread between people and causes flu-like symptoms. How would scientists most likely recommend that the disease be controlled?
Answer:
They would instead focus on controlling and diminishing the rodent population.
Explanation:
They would instead focus on controlling and diminishing the rodent population. The best solutions are always those that target the cause of the problem. Therefore, since the cause of the virus are rodents and that is how the virus spreads, then targetting the rodent population would be the best choice. The scientists would have to figure out a way of keeping track and controlling where the rodent population moves, as well as figuring out how to control their reproduction and diminish their population size. All of this while also trying to predict the possible effects that the population size can have on the environment.
