When a neuron receives both inhibitory and excitatory impulses from neighboring neurons at the same time, the neuron undergoes a process called summation to determine whether it will fire or not. A neuron is a specialized cell that is responsible for the communication of information within the nervous system.

Excitatory and inhibitory impulses are the signals that a neuron receives from neighboring neurons. In contrast, an inhibitory impulse is a signal that hyperpolarizes the neuron, making it less likely to fire an action potential. Summation refers to the process by which a neuron integrates all of the signals it receives to determine whether it will fire an action potential.

There are two types of summation: spatial summation and temporal summation. Spatial summation refers to the addition of signals from multiple synapses, and temporal summation refers to the addition of signals that arrive at different times .If a neuron receives both excitatory and inhibitory signals at the same time, the signals will summate. If the excitatory signals are stronger than the inhibitory signals, the neuron will depolarize and fire an action potential.

In contrast, if the inhibitory signals are stronger than the excitatory signals, the neuron will hyperpolarize and will not fire an action potential. If the excitatory and inhibitory signals are of equal strength, the neuron will not fire an action potential.

Animals classified as amphibians, or members of the class Amphibia, include frogs.

Thus, Amphibians are land and aquatic creatures that occasionally solely live in the water until they are completely grown.

They have wet skin that allows water to enter and exit, and the majority of them spend a portion of their lives in the water (during the tadpole-like larva stage before they mature). Amphibian literally translates as "both life."

Frogs and toads have about 2,000 species, salamanders (including newts) have about 300 species, and caecilians have about 160 species. There are three orders of amphibians.

In 1855, noted physician Rudolph Virchow concluded that cells come from preexisting cells, and the one that is true is that chromosomes are copied during mitosis, which is option D.

Rudolph Virchow's conclusion that cells come from preexisting cells supports the third component of the cell theory. Before Virchow's work, it was commonly believed that cells could arise spontaneously from non-living matter. However, Virchow's observations and experiments provided strong evidence that cells could only arise from preexisting cells. In the mid-1800s, Virchow studied cell division and observed that cells divide to form new cells. He proposed that cells could only come from other cells and that this process of cell division was responsible for the growth, development, and repair of living organisms.

Hence, the one that is true is that chromosomes are copied during mitosis, which is option D.

Plants eliminate waste products generated during photosynthesis through a process called transpiration. The primary waste product of photosynthesis is oxygen, and it is removed from the leaf through small openings called stomata.

During photosynthesis, plants absorb carbon dioxide and release oxygen as a byproduct. Oxygen molecules diffuse out of the leaf cells and accumulate in the intercellular spaces within the leaf.

From there, oxygen moves into the stomata, which are tiny pores on the surface of leaves. Stomata are open and close to regulate gas exchange and water loss. When the stomata are open, oxygen is released into the surrounding atmosphere through diffusion, effectively removing it as a waste product.

Transpiration, the process by which water vapor evaporates from the leaf's surface, also helps in the removal of waste products. As water evaporates from the leaf through the stomata, it carries away any dissolved gases, including oxygen.

This process ensures that waste products of photosynthesis are efficiently eliminated from the leaf and allows for the exchange of gases necessary for plant respiration.

The two reasons for measuring the absorbance of a sample at its λmax are better sensitivity to distinguish two similar concentrations of the same chemical compound and absorbance is more accurate, the error in determining concentration will be lowest.

The λmax (or maximum absorbance) is defined as the wavelength at which the sample absorbs the most light. It is critical to determine the λmax of a sample since it helps in detecting a particular molecule's presence and concentration. λmax is determined with the help of spectrophotometry or other analytical tools, and it aids in analyzing and detecting molecules in a range of fields such as medicine, biology, and environmental science.

Measuring the absorbance of a sample at its λmax provides better sensitivity for determining concentrations of the same chemical compound that are comparable. The amount of light absorbed by the sample is proportional to the concentration of the sample at a given wavelength. By analyzing the absorbance spectrum of a sample, it is possible to identify the concentration of the sample.

Measuring absorbance rather than concentration provides a more precise measurement since the error in determining concentration is lowest in this case. By measuring absorbance, we get a more accurate indication of the amount of light that the sample absorbs. A standard curve that plots the relationship between absorbance and concentration can be used to determine the concentration of the sample with better accuracy.

There are a number of structural differences between cardiac muscle and skeletal muscle, which contribute to the conduction of excitation and contraction of cardiac muscle. The most important of these are the presence of intercalated disks, the presence of gap junctions, and the branching nature of cardiac muscle fibers.

The presence of intercalated disks:Cardiac muscle cells are connected to one another by intercalated disks, which are unique to cardiac muscle. These disks contain both desmosomes, which anchor the cells together, and gap junctions, which allow electrical impulses to travel rapidly from cell to cell. The presence of these intercalated disks allows the heart to function as a single functional unit, with each individual cell contributing to the overall contraction of the organ.

The presence of gap junctions:Gap junctions are specialized channels that connect the cytoplasm of adjacent cells. In cardiac muscle, these junctions allow electrical impulses to travel rapidly from cell to cell, enabling the heart to contract in a coordinated and synchronized fashion. In contrast, gap junctions are absent in skeletal muscle, which relies on the nervous system to coordinate its contractions.
