The tendency to respond to a conditioned stimulus that is similar, but not identical, to the original conditioned stimulus is called _____.
The tendency to respond to a conditioned stimulus that is similar, but not identical, to the original conditioned stimulus is called Stimulus generalization.
Stimulus generalization is the capacity to react in a new situation using a strategy learned in previous, comparable situations. The difficulty lies in determining which aspects of the learning circumstances ought to be applied to all circumstances.
The phenomenon is known as stimulus generalization when an organism's response that was conditioned by one stimulus can be elicited by another stimulus with the same properties. A stimulus that has the potential to elicit a conditioned response is known as a conditioned stimulus. In the experiment that has been described, the ringing of the bell served as both the conditioned stimulus and the conditioned response.

No every part of an organism have the same chance of becoming fossilized . Hard parts of the body preserve because they have biologically deposited minerals.
Fossilization can be defined as the physical, chemical, and biological processes that lead to the preservation of plant and animal remains over time.
Fossils include the organisms remains, such as plant or animal tissues, shells, teeth or bones, they also include traces of life such as foot prints.

suppose that fish size is a heritable trait in a population of fish. the allele conferring large size (s) is incompletely dominant to the allele conferring small size (s). heterozygotes (ss) are of intermediate size. suppose that a population of fish is at hardy-weinberg equilibrium and the frequency of the s allele is 0.9. what proportion of the next generation will be of intermediate size?
The proportion of dominating people in the following population is (1+4)%, or 5%.
The Hardy-Weinberg rule states that in the absence of evolutionary driving forces, allele and genotype frequencies in a population remain constant.
It claims that the binomial expansion of the square of the sum of p and q can be used to describe the total genotype frequencies.
The following sum equals one: (p+q) ²= p²+ 2pq + q².
In this instance, "p" represents the frequency of the dominant allele, and "q," that of the recessive allele. The expression "2pq" represents the population's frequency of heterozygotes.
The frequency of the dominant allele is given by p+q=1, while the frequency of the recessive allele is given by q = 0.9 for a certain hereditary trait. Consequently,
p=1-q
P=1-0.9 = 0.1
p²= (0.1) =0.01 or 1% of the population has a homozygous dominant genotype.
The percentage of heterozygous dominant genotypes in the population as a whole is 4% (PQ)² = 2 X 0.1 X 0.2 ".
∴ (1+4)%
=5%.

which of the following statements about the cytoskeleton is true? although microtubules are common within a cell, actin filaments are rarely found outside of the nucleus. the cytoskeleton of eukaryotes is a static structure most resembling scaffolding used at construction sites. the cytoskeleton is produced by transport vesicles of the endomembrane system. movement of cilia and flagella is the result of motor proteins causing microtubules to move relative to each other. chemicals that block the assembly of the cytoskeleton would have little effect on a cell's response to external stimuli.
The answer is yes this is true, the dynamic aspect of cytoskeletal function is made possible by the assembly and disassembly of a large number of complex proteins into larger aggregates. There are three types of the cytoskeleton: actin filaments (microfilament), microtubules, and intermediate filaments.
What does cytoskeleton mean?All cells, including those of bacteria and archaea, have a complex, dynamic network of interconnecting protein filaments called the cytoskeleton. It stretches from the cell nucleus to the cell membrane in eukaryotes and is made up of identical proteins in different animals.The cytoplasmic protein filament and microtubule network that regulates cell shape, upholds intracellular structure, and participates in cell motility.

In a DNA double helix, adenine pairs with Thymine and guanine pairs with cytosine.
The nitrogenous bases present in DNA are purine (guanine and adenine) and pyrimidine (thymine and cytosine). The process to complementary base pairing rule, the number of purines in DNA is equal to the number of pyrimidines which means in DNA, adenine (A) forms a bond with thymine (T), and guanine (G) forms a bond with cytosine (C).
The number of bonds present between A–T is two ,on the other hand bond between G–C is three. Which means G–C bonds are very hard to break. Uracil is a nitrogenous base present in RNA (ribonucleic acid) and is absent in DNA.

a chain of repeating monomers to make a larger molecule
A chain of repeating monomers to make a larger molecule is called a Polymer.
Monomer-based compounds that combine to form polymers.
Large molecules known as polymers are constructed from single, comparable repeating components (monomers).
A polymer is made up of numerous monomers because the prefix poly- signifies "many" or "multi-."
Any of a group of organic or synthetic compounds known as polymers are made up of macromolecules, or very large molecules, which are just multiples of simpler chemical building blocks known as monomers. Numerous natural and man-made materials, as well as a large portion of the components in living things, are composed of polymers.
A polymer is created when many monomers are linked together. Polymers can be compared to a chain of interconnected paperclips in several ways. A polymer is a big molecule consisting of monomers, which are littler molecules bonded together.
Plastic is a subset of polymer since all plastics are polymers but not all polymers are plastic. Plastics are long-chain molecules created by large monomers while polymers are homogenous molecules created by small monomers. Plastics are manmade materials yet polymers can also be natural.

To draw a cell we have to consider that they are formed by different organelles and structures.

One of the main differences between these two kinds of cells is the cell wall present in plant cells, and the absence in animal cells, which gives a rigid aspect to the former ones, with respect to the latter.

The difference between the macromolecules consumed by Americans and the elemental composition of human body is that these macromolecules provides energy, support and help speed up reactions in them while the elemental composition of human body are used to build proteins, carbohydrates and nucleic acids to perform their respective functions.
How macromolecules provide support.Macromolecules helps to give structural support to the body system through the proteins in our diet by consumption. They do this by acting either as hormones or carriers to aid metabolic activities.
From the task above, we can see that about 78% of carbon in American bodies are from the consumption of corn. Whereas in France, the percentage of carbon which is found in their body system is not upto 78% but 15%.
It has also been proven practically that the food substances consumed by Americans contains majorly of carbohydrates. Lipids and proteins is in low amounts or quantities, roughly almost the same amount.
Macromolecules such as glucose combines with oxygen to produce water, carbon dioxide and ATP in the reaction below:
C6H12O₂ + 6O₂ + 36 ADP+ 36 Pi → 6CO₂ + 6H₂O + ATP

During the Telophase, the daughter chromosomes reach the poles. Telophase passes into the next interphase as the nuclear envelopes and the nucleoli re-form and the chromatin becomes diffuse.
On the other hand, remember that cytokinesis starts during the nuclear division phase called anaphase and continues through telophase. Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells.

Small, nonpolar, hydrophobic molecules such as fatty acids pass readily through a membrane's lipid bilayer.
The cell membrane, which is selectively permeable and controls the passage of molecules into and out of the cell, facilitates the movement of substances or molecules throughout the cell.
A thin polar membrane composed of two layers of lipid molecules is the lipid bilayer. These membranes are flat sheets that surround all cells and act as a continuous barrier.
A lipid-rich cell membrane will not repel small, nonpolar hydrophobic molecules like fatty acids, so they enter the cell through simple diffusion. This indicates that they easily and without assistance penetrate the lipid bilayer of a membrane. Because they are a class of lipids and soluble in the lipid layer of the cell membrane, fatty acids are able to pass through the lipid-bilayered membranes easily.
