Janet and Wade Smith are members of a two-income family. Together they make enough money to afford a house in a low-crime neighborhood with good schools. According to Maslow's hierarchy of needs, the Smiths have fulfilled their need for
esteem.
self-actualization.
physical satiety.
safety.
The Smiths have satisfied their need for safety in accordance with Abraham Maslow's hierarchy of needs.
Human motivation can be explained with the help of various psychological theories. Abraham Maslow's hierarchy of needs is one such theory which tries to define human behavior on the basis of several needs which can be organized in a hierarchical order. The need for safety comes after the physiological needs in the hierarchy.
The need for safety arises only when the basic physiological needs ( air, thirst, hunger, etc.) are fulfilled. The need for safety translates a person's need to be free from any kind of threat or danger in their surrounding environment.

Which of the following processes must occur before cell division begins?And why is it not cytokinesis
Let's take a look at the diagram for the cell cycle:
Recall that the order is from G1 phase to Telophase, where cells ready to undergo cell division start in interphase.
Let's define our answer choices:
0. Shrinkage of the nucleus
,1. DNA duplication
,2. Cytokinesis
,3. DNA segregation
We are trying to find which of these answer choices occurs before cell division (which is known as mitosis/meiosis depending on the type of cell).
We can see from the cell cycle diagram that the stages before mitosis would be the G2 phase, the S phase, and the G1 phase.
Let's go through each of our answer choices:
0. Shrinkage of the nucleus - this answer choice ,never, happens in the cell cycle. The nucleus ,dissipates, or ,dissolves, away when the cell is ready to undergo mitosis.
,1. DNA duplication - this answer choice is ,correct,. DNA duplication occurs during the ,S phase,, which is ,before, mitosis (cell division).
,2. Cytokinesis - this is when the 2 cells during mitosis split and become 2 separate cells. This would signify the ,end, of mitosis, so this answer ,would not be correct,.
,3. DNA segregation - this answer choice happens ,during, mitosis. Therefore, this answer choice is not correct.
Therefore, our answer choice is B.
Describe the strongest theoretical perspective to frame social problems of institutions across work education family and medicine including why you feel it’s the overall strongest perspective. First describe details of theoretical perspective as it relates to social institutions then explain why it’s the strongest three perspectives.
Social life is not complete without social difficulties. The term "social problem" refers to social circumstances, procedures, societal norms, or behaviors that are typically regarded as undesirable, detrimental, or endangering a number of values or interests, including social cohesion, the upholding of law and order, morality, the stability of social institutions, economic prosperity, or individual liberties. A social issue can also be perceived as a sense of collective guilt brought on by a failure to eliminate or improve certain unfavorable social situations that have a detrimental impact on particular segments of society.
Therefore, there is no presumption of value- or attitudinal neutrality in perception, interpretation, or intervention in this description of social issues. This specific characteristic distinguishes social phenomena that are seen to be social issues from other social or physical phenomena or situations that are thought to be difficulties tout court and that are possibly considered as not quite desirable or pleasant but without an element of threat.

Kangaroos are mammals, like humans. Like other mammals, they reproduce sexually with sperm fertilizing an egg that develops into an embryo. Unlike humans, however, once the embryo consumes its yolk sac to develop, it must be born. The infant is
about the size of a lima bean, mostly undeveloped except for its two front arms. It uses these to climb up its mother's abdomen and into her pouch. Once there, it feeds
on its mothers milk and continues to develop until it's big enough to finally leave. The muscle cells of a kangaroo organize together to form the structures that let a
kangaroo walk, run, and hop, allowing it to avoid predators.

When did humans stop evolving?
Evolution is any modification or change in the organism's characteristics over many generations. The most recent evolution within Homo sapiens populations is about 50,000 years ago. This refers to evolutionary adaptation, sexual and natural selection, and genetic drift.
Humans are still undergoing evolution. Changes to adapt to environment is a genetic change and therefore considered as evolution. Blue eyes is considered as an evolutionary trait of humans recently. It came from a mutation from an ancestor 6,000-10,000 years ago. This just means that humans will continue to evolve because evolution is considered as a slow process that will take many generations.

What are some structural similarities between most viruses and what are the functions of these parts?
The basic structure of a viruses is constituted by genetic material, which could be DNA or RNA, surrounded a protein structure called capsid. The genetic material, as in not viral life forms, carries the information necessary for the virus reproduction inside an infected cell.
Enveloped viruses: some viruses have a lipid coat with protein spikes (glucoproteins) to recognize possible hostage cells.
How the covid-19 and omicron viruses affects the peripheral nervous system .
Coronaviruses have been shown to spread back along the nerve from the peripheral nerve endings, across the synapses, and thus enter the brain, in several small animal studies. This is facilitated by the presence of a pathway for endocytosis or exocytosis between neurons of the motor cortex, and another secretory vesicular pathway between neurons and satellite cells.
Fast axonal transport occurs by employing axonal microtubules, allowing the virus to reach the neuronal cell body by a retrograde version of this mechanism.
Possible olfactory route spread is signaled by the occurrence of isolated anosmia and ageusia. In such a case, the virus could cross the cribriform plate to enter the central nervous system (CNS) from the nose. However, newer unpublished research suggests that olfactory neurons lack ACE2, while cells in the olfactory epithelium do. This could mean that viral injury to the olfactory epithelium, and not to the olfactory neurons, is responsible for anosmia, but further studies will be required to confirm this.

Genes A, D, and E are on the same chromosome. The crossover frequency between D and E is 0.30, between A and E is 0.17, and between D and A is 0.13. Which two genes are farthest apart?
Genes D and E are farthest apart on the same chromosome.
The value of crossover frequency between genes D and E is the highest, therefore, these two genes lie furthest apart on the same chromosome. As a general principle, the probability of a crossover between two particular genes is directly proportional to the distance between them. In other words, it can be said that the larger the value of the crossover frequency between two genes, the greater is the distance between them.
The unit centimorgan (cM) is generally used to estimate the distance between genes. One centimorgan is equal to hundred times the crossover frequency.

Which type of mutation do you hypothesize led to the delta variant of SARS-CoV-2?A.new generic combinations through meiosis B. Errors occurring during the replication processC.mutations caused by environmental factors Which answer is correct ?
Viruses are likely to get mutations due to the fast reproduction cycle, this can lead to different replication mutations. the rate of mutations induced by the DNA polymerase is 1/100,000, it is low, but due to the fast spread of the viruses, it could induce some changes.
But one of the main characteristics of the Delta variant is its ability to evade the immune system, so I would say that the mutations that led to this variable were the environmental factors, because it adapted to be more contagious and also to be able to spread easily.
But to give the right answer it is necessary to look into the specific mutations this variable has in regard to the ones that come before.
The information in DNA is coded in its sequence. Which of the following correctly describes the relationship between a change in the sequence of a cell's DNA, the proteins produced by that cell, and the function of the body tissue that the cell is part of? A. A change in the sequence of a cell's DNA can change the structure and function of the proteins produced, which can affect the proper functioning of the body tissue. B. A change in the sequence of a cell's DNA will always change the structure and function of the proteins produced, and will cause the function of the body tissue to improve. C. A change in the sequence of a cell's DNA does not change the structure or function of proteins, but will cause the body tissue to stop functioning. D. A change in the sequence of a cell's DNA can alter the structure and function of proteins, but does not have an effect on the function of the body tissue.
A mistake in DNA sequence is called missence mutation that results in an incorrect amino acid fused into a protein. Due to such changes which the ribosome will know will result in a peculiar amino acid codon. It will cause the protein to be deficient in its function.
Answer - Option A
Answer:
A
Explanation:
Option A correctly describes the relationship between a change in the sequence of a cell's DNA, the proteins produced, and the function of the body tissue. DNA carries the genetic information that determines the sequence of amino acids in proteins. When there is a change or mutation in the DNA sequence, it can alter the structure and function of the proteins produced by the cell. Since proteins play crucial roles in various cellular processes and functions, any change in their structure can have significant effects on the proper functioning of the body tissue.

What is ATP and why does it have stored chemical energy? What important polymer will you find adenosine monophosphate in (take note of what is attached to carbon #2)
ATP is an adenosine triphosphate, the energy-carrying molecule found in the cells of all living things. ATP works as a shuttle, capturing energy from the breakdown of food and transferring it to the parts of the cell that require energy to run their processes.
ATP has stored chemical energy in the pyrophosphate bond, which lies between the last two phosphate groups of ATP. When the cells need energy to do any work, ATP cleaves the third phosphate group, releasing a large amount of energy stored in the bond between the third and second phosphate group. Energy is required for all the cell’s activities. This includes visible activities, such as muscle movement when running or talking, as well as those that cannot be seen by the human eye, such as the nerve impulses involved in thinking or feeling. ATP provides energy for all these processes.
The important polymer where adenosine monophosphate is found is RNA. Adenosine monophosphate (AMP) is one of the components of RNA.
