Joe has been diagnosed with major depressive disorder. He interprets negative stressful events using a pessimistic explanatory style. This explanatory style creates a hopeless, depressed state, which then hampers the way he thinks and acts, causing more negative stressful events. Joe's depression is thus, at least in part, due to:
state-dependent memory.
rumination.
a biochemical imbalance.
indicators of depression.
Answer:
The correct answer is : state - dependent memory.
Explanation:
State dependent memories are recollections of memories that are set off or enhanced or increased by an individual's present mind-set in view of the relationship to memories framed when you were in a comparative state.
For example, pleasant memories are all the more effectively or strongly recalled when one is feeling happy and the equivalent goes for negative thoughts and sadness or outrage towards something. In this case Joe having more negative thoughts in response of depression or negative thoughts.
Thus, the correct answer is : state - dependent memory.
Joe's depression caused by pessimistic explanatory style of negative events is due to State dependent memory,
State dependent memory:
It is phenomenon in which people recall more information if their mental or physical state is same as the time event.
Here, pessimistic explanatory style makes Joe to recall depressive events that cause more depressive events to come.
Therefore, Joe's depression caused by pessimistic explanatory style of negative events is due to State dependent memory,

The scuba diver is a living system. The scuba gear, or self-contained underwater breathing apparatus, is a system of air exchange. How are these two systems interacting? What are the inputs and outputs of these systems?
Answer:
Input: oxygen (or air generally), breathed in by the scuba diver
Output: carbon dioxide exhaled by the scuba diver
Explanation:
The scuba gear is absolutely essential to sustaining this activity by sea divers. It serves the purpose of recycling the air breathed out by the person by filtering out the carbon dioxide. It also makes up for the oxygen that gets used so that the diver can continue breathing in a circuit. Thus, oxygen is considered as input and CO2 as output in this case.
A period in 24-point font (.) is about 1mm in diameter. SARS-CoV-2 has a diameter of 80 nm. The prefix “milli” means 1000, which tells you there are 1000 millimeters (mm)in a meter. The prefix “nano” means 109 (1 billion), which tells you there are 1 billion nanometers (nm) in a meter. Approximately how many SARS-CoV-2 viruses could fit in that period? (Hint: There are 106nm in 1mm).
Answer:
Approximately 12,500 SARS-CoV-2 viruses
Explanation:
According to this question, the period described is 1mm in diameter. Since 1millimetre(mm) is 1000metre(m), this means that the period is 0.001m in diameter.
Also, the SARS-CoV-2 virus has a diameter of 80 nm (1nm = 10^9m).
Since 10^6nanometres (nm) or 1,000,000nm makes 1millimeter (mm), 80nm of the virus will be:
= 80/1,000,000
= 0.000080mm or 8 × 10^-5mm
To calculate how many of the SARS-CoV-2 virus will fit into the period, we divide the diameter of the period (in mm) by the diameter of the virus (in mm).
That is; 1 ÷ 8 × 10^-5
= 1/8 × 10^5
= 0.125 × 100,000
= 12,500
Therefore, approximately 12500 SARS-CoV-2 viruses will fit in the period.

Similar to Protists, Archaea can reproduce to generate two genetically identical daughter cells through Binary fission.
What is Binary fission?Binary fission may be defined as a type of asexual reproduction in which an organism significantly duplicates its genetic content. According to this, the deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
According to the context of this question, binary fission is a mechanism of reproduction in simpler organisms through which a parent cell divides into two genetically identical daughter cells.
Archaea can also reproduce asexually through budding and fragmentation, where pieces of the cell break off and form a new cell, also producing genetically identical organisms.
Therefore, similar to Protists, Archaea can reproduce to generate two genetically identical daughter cells through Binary fission.

Identify the eukaryotic cellular locations of the fundamental processes that are involved in the central dogma of molecular biology by dragging the correct labels to their targets.
Answer:
See the answer below
Explanation:
The central dogma gives a description of how genetic information travels in biological cells from DNAs to proteins. DNAs are first transcribed into messenger RNAs in a process known as transcription and the resulting mRNAs are used in the synthesis of proteins in a process known as translation.
In eukaryotic cells, transcription process happens within the confines of the nucleus because the genetic material in the form of DNAs are always located in the nucleus. Thereafter, the mRNAs generated from transcription are transported to the cytoplasm of the cell where they become translated into proteins.
Hence;
Transcription happens in the nucleus of the cell.Translation happens in the cytoplasm of the cell.identify monomers and describe the function for all macromolecules

In humans there is a dominant allele (A) for the absence of moles; while the recessive allele (a) results in the presence of moles. A couple who are both heterozygous for this locus (Aa) plan to have seven children.
a. Expand the binomial (p + q)7.
b. What is the probability that:
(i) The first child that is born will not have moles.
(ii) All of the children will have moles.
(iii) The first two children will have no moles and the last five will have moles.
(iv) Of the 7 children, 4 will have no moles and 3 will have moles
c. Assume this couple now have two children, one with moles and one without moles. What is the probability that the child born without moles is a carrier of the a-allele (ie heterozygous)?
Answer:
a. [tex](p + q)^7[/tex] = [tex]p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7[/tex]
b. i. 0.75
ii. 0.000061
iii. 0.012
iv. 0.17
c. 0.67
Explanation:
a. The expansion of the binomial (p + q)7 would be such that:
[tex](p + q)^7[/tex] = [tex]p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7[/tex]
b. Both couples are heterozygous:
Aa x Aa
AA Aa Aa aa
Since A is dominant over a,
probability of having mole (aa) = 1/4
probability of not having moles = 3/4
Therefore, the probability of the first child not having moles = 3/4 or 0.75
ii. Let the probability of not having mole = p and the probability of having mole = q. From the binomial expansion:
[tex](p + q)^7[/tex] = [tex]p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7[/tex]
Probability that all of the children will have moles = [tex]p^0q^7[/tex]
since p = 3/4 and q = 1/4
[tex]p^0q^7[/tex] = [tex](3/4)^0(1/4)^7[/tex] = 0.000061
iii. Probability that the first two children will have no moles and the last five will have moles = [tex]21p^2q5[/tex]
= [tex]21(3/4)^2(1/4)^5[/tex]
= 0.012
iv. Probability that 4 will have no moles and 3 will have moles out of the 7 children = [tex]35p^4q^3[/tex]
= [tex]35(3/4)^4(1/4)^3[/tex]
= 0.17
c. Probability that the child born without moles is a carrier of the a-allele = probability of heterozygous.
From the cross in (b), the genotypes of those born without moles are AA and 2Aa. Therefore, the probability of not having moles and be Aa is:
= 2/3 or 0.67
Researchers have suggested that people can be divided into chronotypes. A chronotype identifies an individual as a(n)
Answer: morning type or an evening type
Explanation: According to research, a chronotype identifies an individual as a morning type or an evening type. By definition, a chronotype is the natural disposition of an individual to be more alert or lethargic at different times of the day (especially in the morning or in the evening), depending on a variety of factors associated with circadian rhythms (the 'internal body' clock that regulates the 24-hour cycle of biological processes in both animals and plants).
Plate tectonics is the theory that the Earth’s crust is made up of plates that glide over a layer of mantle. A prediction of this theory is that the plates will move relative to each other as they move over the mantle. To test this hypothesis, a scientist places a marker on two adjacent plates to measure their movement over a decade. What would be the expected result of the experiment? How would you interpret the results if the scientist sees no movement?
Answer: So the result of this experiment would be that the makers are either further away from each other or closer to each other, confirming that the tectonic plates which are moving and are not static. North America plate, and on the South American plate, they move at pretty much the same speed, and also in the same direction, so with setting up makers we can not get to valid result. This is why they don't see no moment.
Answer: The result for this given experiment is that makers are further away from each other or closer to each other. North america plate and the south plate can move at the same speed, the same direction, by the same time. This is why they don't see no movement.
If a splice site were mutated so that splicing could not take place, what would the effect be on the mRNA?
Answer:
The mRNA will contain intron sequences and eventually be translated into a non-functional protein.
Explanation:
Splicing is the last stage involved in mRNA processing (the first two being 5' capping and polyadenylation). A mRNA transcript (result of transcription) contains both protein-coding regions (exons) and non-coding regions (introns). Splicing involves the removal of the introns from the mRNA sequence (by spliceosomes) and the rejoining of the exons.
If the site where splicing process should occur were mutated and splicing does not take place, this means that the introns will not be removed from the mRNA sequence, hence, the final transcript will contain both protein coding and non-coding regions.
If translation (synthesis of protein) eventually occurs, the mRNA that didn't undergo splicing will be translated into a protein molecule that is not functional. This is because the non-coding sequences will interfere with the reading frame of the coding sequences.

Answer:
The independent variable in the experiment is A. the jar covers.
Explanation:
The independent variable in an experiment represents the thing that the person conducting the experiment changes or alters. One group in the experiment had covers (this represents the experimental group) and the other group had no cover (this represents the control group which was not exposed to the independent variable). Since the only thing that Redi changed between the two groups was whether or not the jars were covered, this represents the independent variable.
The number of jars and the contents of the jars were constant in both experiments, and the number of maggots on the meat is the dependent variable (the result of changing the independent variable).

Why are jenner's vaccine superior to previous methods for conferring resistance to smallpox?
Answer:
The risk of disease transmission is drastically low with his method, compare to the previous method with great tendency of transmitting diseases,which were lethal to the recipient.
Explanation:
He had noticed that milkmaids were only affected with cowpox,but are not affected with small pox.Thus he reasoned that they must have immunity against small pox.
Through his crude methods he extracted pus from a milkmaid who carried the virus for cowpox,and inserted this into the arm of a young through the opening created. After latent period of days he exposed the boy to the smallpox,and surprisingly he was not infected,thus the boy developed immunity to this virus which was related to the virus injected.
Thus he was able to develop immunity against the related diseases.
Besides he observed that this boy did not show symptoms of any other diseases or infection.

Answer:
During latent period, the muscle is preparing itself for contraction which comprises of biochemical activities from the stage acetylcholine bind to sarcolemma through cross-bridge formation.
Explanation:
A single muscle twitch has three stages which are latent period, contraction phase and relaxation stage
During latent period, the muscle is preparing itself for contraction which comprises of biochemical activities from the stage acetylcholine bind to sarcolemma through cross-bridge formation because the latent period is a short delay from the time the action potential get to the muscles until tension can be seen clearly in the muscle and the action potential is being propagated along the sarcolemma.
