For a hypotonic solution the movement of water is from the solution to the cell, in isotonic solution there is no net movement and for hypertonic solution the movement of water is from the cell into the solution.

Hypotonic solution is the one where the concentration of solute is less as compared to the cell. This is the reason why movement of water is from solution to the cell and the animal and plant cell become lysed and turgid respectively.

Hypertonic solution is the one where the concentration of solute is more as compared to the cell. This is the reason why movement of water is from cell to the solution and the animal and plant cell become shriveled and plasmolyzed respectively.

According to Darwin's theory of evolution, species evolve over time through the process of natural selection, where individuals with advantageous traits are more likely to survive and pass on their traits to their offspring.

Over many generations, these small changes can accumulate, leading to the formation of new species.

The finches that live on the Galapagos Islands provide a classic example of how this process works. Darwin observed that different species of finches on the islands had evolved different beak shapes that allowed them to specialize in eating different types of food, such as seeds or insects. This adaptation to their environment was key to their survival and allowed them to successfully reproduce.

In this sense, the finches can be compared to members of a family tree, where each generation passes on traits to the next generation. The variations in beak shape among the finches are analogous to genetic variations that arise in a family tree through the process of genetic recombination and mutation. By studying these variations, we can learn about the evolutionary history of a species and how it has adapted to its environment over time.

The answer is "\(\bold{4.0 \times 10^7 \ \frac{CFU}{mL}}\)"

Explanation:

The very first thing we must do is figure out where the plate was really a countable sheet.  By default, at least 30 and 300 colonists must have been on a computable plate. It is deemed incorrect beyond and below this range.  We also will pick the studded 0.25 size, leading towards 72 and 65 colonies. Now calculate the double average.

\(\to 72+ \frac{65}{2} = 68.5\)

We need to calculate its dilution factor for both the second item. Increase for all of this  

All of the dilutions you also made:

\(\to \frac{7}{17} \times \frac{1}{60} \times \frac{1}{1000} \\\\= \frac{7}{1020000}\\\\= 6.8 \times 10^{-6}\)

Only once bacteria come into touch with carbapenems do they develop resistance. This bacterial drug resistance is an illustration of how non-resistant bacteria can mutate into resistant strains.

The original "carbapenem," thienamycin, would become the parent or model compound for all subsequent carbapenems. Recent research demonstrates unequivocally that carbapenem resistance is growing globally. In particular when porin losses occur, excessive synthesis of weak carbapenemases as CMY-10 and PDC Beta-lactamases might result in carbapenem resistance. Gram-positive bacteria develop resistance to carbapenems and other beta-lactam antibiotics through mutation-derived modifications to their PBPs, whereas Gram-negative bacteria frequently enlist the help of additional defense mechanisms to combat the effects of these drugs.

Answer:

Water is essential to all living things because people or animals could die if not eat or drink water everyday like health.

Explanation:

When X fires 10 times and Y fires 10 times, the result will be a subthreshold summation.

Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.

Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.

When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).

Therefore, when X fires 10 times and Y fires 10 times, the postsynaptic neuron will experience subthreshold summation and no action potential will be fired.

"The derived shared characteristic 'Terrestrial during all stages' should be placed at the base of the tree diagram."

SupThe characteristic "Terrestrial during all stages" is a shared characteristic among all five species being compared in the branching tree diagram. This means that it is a characteristic that all of these species have in common, and therefore it is likely that it was present in their common ancestor.

Since the base of the tree represents the common ancestor of the species being compared, it makes sense to place this characteristic at the base of the tree. This also helps to show that this characteristic is a defining trait of the group of species being compared and that it has been present in their lineage since their common ancestor.

Answer:

Cell wall, chloroplast, vacuole. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

Explanation:

The main difference between plant cells and animal cells are cell wall and chloroplast , whereas for the vacuole plants have a vacuole called vescile which is not the same as the vacuole in plant cells.

Vacuoles are very large as they are needed to store water and they mostly contain water and sugars . On the other hand, vesicles are small and contain water, nutrients, enzymes, wastes, solution of water or food etc. This is the key difference between vacuoles and vesicles. hope it helps :)

The protein has a lysine or arginine at it's C-terminal end.

Explanation:

Hello. You have not introduced the methods used to denature the egg albumin. However, the most efficient protein denaturation method is the heating method.

The denaturation of a protein, such as albumin, occurs when an element causes the complete destruction of the protein's three-dimensional structure, in a completely irreversible way. The best way to do this is through heat. In this way, through a heating method, the heat breaks the hydrogen bonds that promote the structure of the protein, leaving it completely denatured.

The primary root or radicle grows from the seed while the lateral roots come from founder cells in the pericycle or the outermost layer of the vascular cylinder.

An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.

It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch).

For example, if you are measuring how the amount of sunlight affects the growth of a type of plant, the independent variable is the amount of sunlight.

An easy way to think of independent and dependent variables is, when you're conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that.

The atom represented by the model with one valence electron in its outermost shell is most likely to have the lowest ionization energy and hence is most likely to form a cation with a charge of +1.

The atom that has the lowest ionization energy is the one which is most likely to form a cation with a charge of +1. Ionization energy is defined as the energy required to remove an electron from an atom or ion in the gaseous state. Therefore, an atom with a low ionization energy requires less energy to remove its outermost electron and form a positively charged cation.

Among the models of atoms given, the atom represented by the model with one valence electron in its outermost shell is most likely to have the lowest ionization energy. This is because the valence electron is loosely held by the nucleus due to its large distance from it. As a result, it requires less energy to remove the outermost electron and form a cation with a charge of +1.

For example, Lithium (Li) has one valence electron in its outermost shell and has the lowest ionization energy among the elements in the first group. This makes it easy for Lithium to lose its valence electron and form a cation with a charge of +1.

In summary, an atom with a low ionization energy requires less energy to remove its outermost electron and form a positively charged cation.

Alexa can obtain c)structural evidence from studying fossils of a extinct species.So,correct option is c.

A fossil is any safeguarded remains, impression, or hint of any once-living thing from a past topographical age. Models incorporate bones, shells, exoskeletons, stone engravings of creatures or microorganisms, objects saved in golden, hair, froze wood and DNA remainders. The entirety of fossils is known as the fossil record.

Paleontology is called as the study of fossils: their age, strategy for development, and transformative importance. Examples are normally viewed as fossils assuming they are north of 10,000 years old. The most seasoned fossils are around 3.48 billion years old to 4.1 billion years old. The perception in the nineteenth century that specific fossils were related with specific stone layers prompted the acknowledgment of a geographical timescale and the overall periods of various fossils.

They became extinct, so they did not exist when the younger rock layers formed. Option D.

The most likely scenario based on the information provided is that the organisms that became fossilized in older rock layers became extinct, and therefore, they did not exist when the younger rock layers formed.

Fossils are the preserved remains or traces of organisms from the past, and they provide valuable insights into the history of life on Earth. The distribution of fossils in rock layers follows the principle of superposition, which states that younger rock layers are deposited on top of older ones.

This implies that the fossils found in older rock layers represent organisms that lived in the past and were preserved through the fossilization process.

If the older rock layers contain fossils of many kinds of organisms that are not found in younger rock layers, it suggests that those organisms no longer existed by the time the younger rock layers formed. The absence of their fossils in younger layers indicates that either the organisms became extinct or their populations shifted to different habitats or regions where their remains were not preserved as fossils.

This phenomenon aligns with the concept of extinction, which is the complete disappearance of a species or a group of organisms. Extinction can occur due to various factors such as environmental changes, competition, predation, or other selective pressures.

Organisms that became extinct would not be present in subsequent rock layers because they were no longer alive or did not have a viable population to leave behind fossil remains.

Therefore, the most reasonable explanation is that the organisms that became fossilized in older rock layers became extinct, and this is why they are not found in younger rock layers. SO Option D is correct.
