The psychological phenomena that occurs to individuals with longer periods of ketosis is : Anxiety
The best natural state of the human body is to be in equilibrium ( homeostasis) while sometimes the body goes into an unstable state ( ketosis ) especially due to the deficiency of carbohydrates in the human system.
Ketosis : this is a process where the body system burns up fat stored in body to produce ketones which is used as a source of energy by the body. this process occurs due to deficiency of carbohydrates in the human system, the state of ketosis has some effect on the brain and this causes the release of GABA a neurotransmitter in the brain.homeostasis : this is a state of the human whereby the body is able to maintain/stabilize all the internal variables related to the human body, such as :temperature
emotion level
water level
Hence due to the release of a neurotransmitter ( GABA ) in the brain during ketosis the psychological phenomena that occur during ketosis is ANXIETY

According to the diagram below, which of the following is a derived characteristic of flatworms?
A. Flatworms do not have a coelom.
B. Flatworms are multicellular.
C. Flatworms have a pseudocoelom.
D. Flatworms show protostome development.
were any of the features used in more then one phylum
Answer:
No.
Explanation:
No, the features is not used in more then one phylum because every phylum has its own unique characteristics which makes it unique from other phylum. Every phylum is different from one another due to its different features and characteristics so one feature that is present in one phylum is not present another phylum so we can say that any of the features were not used in more then one phylum.
The diagram below depicts the Linnaean classification system and a
cladogram. How do the two methods of classification compare?
A. Extinct organisms have a place in the Linnaean system, but not in
a cladogram
B. The Linnaean system attempts to show how organisms ans
related, but a cladogram does not.
C. The Linnaean system establishes a scientific naming system, but
a cladogram does not
D. The Linnaean system presents the probable order of evolution of a
set of organisms, but a cladogram does not
Answer:
C. The Linnaean system establishes a scientific naming system, but a cladogram does not.
Explanation:
The main difference between Linnaean classification system and a cladogram is that the Linnaean system establishes a scientific naming system, but a cladogram does not. Cladogram refers to a branching diagram which shows the cladistic relationship between different species while on the other hand, the Linnaean system of classification consists of taxa that is range from the kingdom to the species.
hi,I was feeling so bored so I give this question What is climate change and what r the causes of climate change?
Answer:
Climate change is the global phenomenon of climate transformation characterized by the changes in the usual climate of the planet (regarding temperature, precipitation, and wind) that are especially caused by human activities
Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming. Humanity’s increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry
Deforestation – because living trees absorb and store carbon dioxide
Increasingly intensive agriculture – which emits greenhouse gases like methane and nitrous oxide

When flies having a gray body and normal wings were crossed with flies having a black body and vestigial wings, the F2 generation showed a phenotypic ratio of 3:1, and not 9:3:3:1.
Answer:
This proves Gregor Medel's hypothesis.
Explanation:
When Gregor Mendel crossed two pure-breed flowers, he noticed that the offspring in the F1 generation exhibited all dominant traits. However, when he crossed the offspring in the F1 generation, he noticed that the recessive trait reappeared in a 3:1 ratio (one reccesive). This is because for each trait, one allele from each parent is passed on. Also, the alleles are passed independently of one another, meaning that one allele passed for one trait won't affect the chance of another.
In a case-control study, a researcher found no association between exposure to A and disease B. Later she found out that there was a misclassification when measuring exposure to A, in both cases and controls. What is a potential explanation for the results (no association) of this case-control study?
a. Differential misclassification
b. Confounding
c. Selection bias
d. Effect-modification
e. Nondifferential misclassification
Answer:
e
Explanation:
When misclassification occurs among the probability of individuals being misclassified is equal across all groups in the study it is referred as non-differential misclassification.
What is misclassification?An error that occurs during a research at any stage is known as misclassification.
It can be differential misclassification of non-differential misclassification.
Non-differential misclassification takes place in case when the probability of misclassification is equal across all groups in the study.
Differential misclassification occur in a case when the probability of misclassification differs between particular groups in a study .
In the given case exposure A is misclassified in both cases. So, it can be taken as non-differential misclassification.
Thus, the correct option is e.

What does it mean that a hypothesis must be ‘falsifiable’ in order to be valid?
\
Answer:
A hypothesis must be able to be proved wrong for it to be a useable hypothesis.
Explanation:
This is because if one can not disprove a hypothesis no experiment can be preformed to test the truthfulness of the statement. this does not mean that the question is not interesting or not worth asking. For example "There is a god" is an example of a hypothesis which is not falsifiable; whether or not this statement is true is still valuable information but it is not possible to answer using the tools of science.
Answer:
If an experimental observation can be made that disproves a hypothesis or model, it is said to be falsifiable. That is, one of the possible outcomes of the planned experiment must be a result that would contradict the hypothesis if achieved..

A therapist examining the roles, rules, expectations, power hierarchy, and boundaries within a
family is focused on which of the following areas of assessment?
Answer:
This question lacks options, options are:
A) family affect
B) family strengths
C) family process
D) family organization.
The correct answer is D.
Explanation:
The family is a system that is constituted by a network of relationships and made up of subsystems where each member evolves and develops through different stages, undergoing adaptation changes where the norms, rules, limits and hierarchies that work are essential in the family environment. Family therapy is understood to be that modality of therapy focused on the family as an object of intervention, its objective is to achieve the change of negative interaction patterns between the members of a family. Family organization refers to the interaction between all its members who are part of the same institution united by emotional ties. The organization describes the totality of the existing relationships between the people that make up the system, then the family organization refers to the functional demands, distribution of rules and transactional guidelines that constitute the ways of interacting of each individual within the family. The transactional guidelines are those that normalize the behavior of each member and are preserved by two systems of coercion; the first established by universal norms in turn existing roles and hierarchies; the second is the characteristic of each member involving its interests and expectations.

Which of the following lists correctly presents levels of organization from most complex to simplest?
O biosphere, community, organism, organ system
O cell, organelle, atom, molecule
O macromolecule, population, community, ecosystem
Answer:
O macromolecule, population, community, ecosystem
Explanation:
Macromolecules are very large molecules composed of atoms, such as complex carbohydrates, fats and proteins (for example, fats are macromolecules mainly composed of C, H, and O atoms). Macromolecules in turn associate to form cellular structures (eg. organelles, cytoskeleton, etc), which subsequently combine to form cells. Individuals are made up of one or more cells (i.e., unicellular and multicellular organisms, respectively). In the next level, populations are groups of individuals of the same species that live within a given area; whereas communities are groups of populations that live in a given area and interact with one another. Finally, an ecosystem can be defined as a group of populations (i.e., a community) and the abiotic factors (i.e., nonliving parts) of their environment that support them (e.g., water, light, radiation, temperature, etc).
