felice has a scar on her arm that happened when she broke a glass at the age of 3. at the age of 8, she asked her mom why she has a scar, and her mom responded that she was bitten by the neighbor's dog. since then, whenever she is asked about the scar, she has a distinct memory of what happened on the day the dog bit her (even though this never happened). this illustrates: the equipotentiality hypothesis the encoding specificity principle the misinformation effect levels of processing theory
Answer:
the misinformation effect
Explanation:
In psychology, misinformation effect occurs when false memories are formed as a result of the misleading information that was provided after the original event has taken place. This effect was studied by a psychologist named Elizabeth Loftus.
Elizabeth Loftus in her series of experiments discovered that false memories about an event can be induced by suggesting or giving wrong information about it. Hence, the involved persons remember a wrong information about the experienced event based on what they were led to remember via wrong information.
This is the case Felice, who was fed with a wrong information about the scar on her arm. This information make her have a false memory of the event i.e dog bite instead of a broken glass
ABO blood typing uses 3 alleles. From your course notes answer the following two questions: Which two are dominant? _________ Write the two dominant allele genotypes, using the capital letter I, and then a superscript for each of them. __
Answer and Explanation:
Given that the ABO blood typing uses 3 alleles
The blood type of ABO could find out by considering three different alleles i.e [tex]I^{A}, I^{B}\ and \ i[/tex]
where,
[tex]I^{A}\ and\ I^{B}[/tex] = co-dominant
i = recessive
The dominant allele genotypes are as follows
For type A = [tex]I^{A} I^{A}/ I^{A}\ i[/tex]
For type B = [tex]I^{B} I^{B}/ I^{B}\ i[/tex]
For type AB = [tex]I^{A} I^{B}[/tex]
Therefore the above two are dominants and the same is to be considered
An arthropod has all the following characteristics except:
a. three embryonic germ layer
b. pseudocoelom
c. bilateral symmetry
d. protosome development
e. true tissues
Answer:
b. pseudocoelom
Explanation:
A pseudocoelom is a false body cavity of some invertebrates which occupies the space localized between the mesoderm and the endoderm of the gut. This false cavity is found in nematodes.
Arthropods exhibit:
1- Bilateral symmetry because both opposite sides of the body are similar,
2- they are protostomes because the blastopore becomes the mouth during embryonic development,
3- they have true tissues because tissues are formed by groups of cells which share a common function, and finally,
4-arthropods are triploblastic because they are formed by three germ embryonic layers (endoderm, mesoderm and ectoderm).
Recall what you know about crossing over, independent assortment, and random joining of sex cells during sexual reproduction. Now, go back to the claims in Step 2a. Do you support these claims? If so, do you support the totality of the claims or just parts of the claims? Based on your prior knowledge, make a claim about the factors that cause inherited genetic variations within populations. Also make a claim about the effects of mutations. Write your claim in your notebook. ASAP!!!!
Answer:
Crossing over is a process in which exchange of segments occur.
Explanation:
Crossing over is a process in which two non-sister chromatids of homologous chromosomes exchange the segments of genetic material with each other during meiosis. Due to this process, variation occurs in an organism.
Independent assortment is a process in which different alleles are sorted to different gametes which occurs independently and does not effect one another. This process occurs in metaphase of meiosis l.
Joining of sex cells is a process in which sex cells of male and female join together formed a zygote which turn into a new organism. These sex cells are formed during meiosis which are haploid in nature.
Mutation and crossing over are the factors that cause inherited genetic variations within populations.
Sudden change occurs in the genes of an organism due to the exposure of the cell to radiation or chemicals.

a strand of dna contains the base sequence AGTT . What is the sequence of the complimentary strand of DNA
Answer:
The sequence is TCAA
Explanation:
Deoxyribonucleic acid (DNA) is a molecule composed of two complementary chains of nucleotides. The nucleotides are in turn composed of one nitrogenous base, one deoxyribose sugar, and one phosphate group. The four different types of nitrogen bases found in DNA are thymine (substituted by Uracil during RNA transcription), adenine, cytosine and guanine. These bases bind by complementary base pairing to form an antiparallel double-strand. The complementary base pairing rule states that thymine forms two hydrogen bonds with adenine, while cytosine forms three hydrogen bonds with guanine.
Answer:
TCAA
Explanation:
A matches to T and G matches to C.

Angiosperms (flowering plants) and vertebrates obtain nutrients from their environment in different ways. a. Discuss the type of nutrition and the nutritional requirements of angiosperms and vertebrates. b. Describe 2 structural adaptations in angiosperms for obtaining nutrients from the environment. Relate structure to function. c. Interdependence in nature is evident in symbiosis. Explain two symbiotic relationships that aid in nutrient uptake, using examples from angiosperms and/or vertebrates. (Both examples may be angiosperms, both may be vertebrates, or one may be from each group.)
Answer:
a. Angiosperm are plants (autotrophs) that use photosynthesis to produce their own food, while vertebrates are animals (heterotrophs) that obtain their food from other organisms. Vertebrates include fish, amphibians, reptiles, mammals and birds.
b. Adaptations in angiosperms include two reproductive structures 1- fruits (ovaries), whose main function is to disperse the seeds and 2- flowers that ensure pollination and protect the embryo sac during its formation.
c . Examples:
1- The mycorrhizal symbiosis between plant roots and symbiotic fungi plays a key role in nutrient uptake from the soil. Arbuscular mycorrhizal is a type of symbiosis where a fungus of the phylum Glomeromycota penetrates the cortical root cells of vascular plants to produce specialized structures named arbuscules.
2- Microflora in the vertebrate digestive tract. The microorganisms that live in the digestive tract of vertebrate species are beneficial for the absorption of nutrients. For example, in humans, Saccharomyces boulardii has shown to have a probiotic effect by increasing intestinal homeostasis, thereby enhancing nutrient uptake.
What substance are the bacteria (microorganisms) breaking down in the digestive system of cattle? Describe the digestion of this substance.
Answer:
The Bacteria or microorganisms are present in the rumen of cattle that aid in the digestion of cellulose and grains in the digestive system of cattle.
The process of digestion of cellulose by bacteria in cattle is anaerobic digestion and includes two steps – the production of the required enzymes and the fermentation.
In the fisrt step of production of enzyme, the microbes or bacteria are found in the first chamber of the stomach. These bacterias or microbes releases several enzymes that helps in splitting the cellulose into smaller carbs such as glucose.
These smaller carbs are the move to thrd chamber of the stomach and fermented. the required nutrients are absorbed. The digested food then finally reached at fourth chamber (acidic part), where the remained food is digested and passes to the small and large intestines.
Explain the mechanism responsible for summation of contractions and the increase in height of contraction when the stimulus frequency is increased.
Answer:
The higher the stimulation frequency, the contractions will be more continuous and even additive.
Continuous stimuli reactivate muscle contraction once the action potential cycle is complete.
Explanation:
Muscle contractions can be continuous or cumulative once the action potential curve drops, since the action potential at the top of the mountain is in a refractory period.
I knit a graph of what cumulative contractions are like due to continuous stimulation.
In the graph I leave you pointed out some references:
mr = refractory moment
mnr = non-refractory moment (where the new stimulation is accepted and a more powerful cumulative muscle contraction is generated)
PA = potential for muscle action or contraction itself.

The mitochondrion, like the nucleus, has two or more membrane layers. How is the innermost of these layers different from that of the nucleus?
Answer:
The double membrane of the mitochondria is highly folded,and therefore wider when unfolded than that of the nucleus.This is an adaptive feature to increase the surface area for reactions (electrochemical gradient) by accommodating protons pumped into it by the proton motive force(PMF) from the matrix to set up the electrochemical gradients needed to generate the energy needed by ATPase synthase enzymes for ATPs synthesis.
Required number of protons needed to be accommodated by the double membrane to generate enough energy for ATPase synthesis,therefore larger surface area is needed.
Explanation:
Mitochondria is the powerhouse of the cell, which is a membrane-bound organelle found in the eukaryotic cell. The inner layer of the mitochondria has cristae, which is absent in the outer layer.
Mitochondria is a membrane-bound organelle, which is composed of outer and inner layers.
The inner layer has cristae or folds, which increases the surface area for an electrochemical gradient.
The cristae are separated by cristae junctions, which are juxtaposed to the outer layer of the mitochondria.
The inner layer helps in electron transport and ATP synthesis. The membrane is surrounded by the mitochondrial matrix, which helps in the transportation of protein complexes during the citric acid cycle.
Therefore, the inner membrane of mitochondria has cristae whereas, the outer layer lacks the folds.

Explanation:
Living organisms in an ecosystem are usually found in numbers living together in a given area. This is termed POPULATION in ecology. A population refers to the group of living organisms that belongs to the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce with one another.
This is the case in this question where many sandhill cranes (large flying birds) were observed in a particular area, which represented their habitat. Asides the group of sandhill cranes living together, they were also observed to be interbreeding. This was evident in the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.
This observation completes what a POPULATION is all about, hence, a population was observed.
1. Are most invasive (exotic) species K-selected or r-selected species? Explain your choice and why that makes sense in terms of their ecological success.
Answer:
The correct answer is "r-selected species".
Explanation:
The terms "k-selected" and "r-selected" species are used to describe two different type of evolutionary strategies. K-selected species are those who have few offspring that are well adapted to its environment and require a lot of resources to growth and survive. On the other hand, r-selected species have a large number of offspring, which not require living on stable conditions and can survive with few resources. The most invasive species are r-selected, since they reproduce very quickly and can adapt to survive to very different ecological conditions.
