Dr. Morelli investigates how gene activity is regulated within a cell, including what signals switch genes on or off. In general, she is interested in the mechanisms that control gene expression and its effect on behavior and health. Her area of research is called:______.
a) genetic mutation research.
b) epigenetics.
c) stem cell research.
d) the human genome project.

Answers

Answer 1

Answer:

b) epigenetics.

Explanation:

Epigenetics simply indicates the changes that do not alter the DNA sequence but influence the way genes are intercepted by the cells. Chemical compounds externally applied to single genes may modify their activity and these changes are known as epigenetic changes. Epigenetic variations persist as cells divide, and in some cases can be passed from one generation to another. The epigenome may also be influenced by environmental factors, for example, diet, exposure to contaminants, etc.

During a traffic stop, officers can order passengers as well as the driver to exit the vehicle, even if there is no basis for suspicion that the passengers engaged in any wrongdoing according to:

Answers

Answer:

Maryland v. Wilson.

Explanation:

The Supreme Court Case of Maryland v. Wilson in 1997 states that it is lawful for traffic officers to order passengers of a vehicle stopped during a traffic stop. This may be against the Fourth Amendment of the citizen's rights but as the court sees it, the safety of officers was of utmost importance, and thus, the driver as well as the passengers ( if any) can be ordered to exit the vehicle.

This was a result of the case regarding Jerry Lee Wilson who was at the passenger seat of the vehicle when they were stopped at traffic and ordered to step out of the car. Officers noticed his nervous behavior which seemed rather unusual and thus ordered him to exit the vehicle. And when he did that, a good amount of cocaine fell out, he was arrested at the spot with possession of the drug and intention to distribute. So, whether the passengers of a vehicle are liable to be subjected to the same treatment, i.e, ordered to exit the vehicle, is thus deemed valid for the safety of the officers concerned.

Answers

Answer:

This question lacks options, options are:

A. neuroticism.

B. extraversion.

C. openness to experience.

D. agreeableness.

The correct answer is C.

Explanation:

Openness to experience is totally related to the human capacity to seek new experiences in our life, and it also has to do with the ability to creatively visualize the future. People with a high level of openness to experience are imaginative profiles (as Garner), who appreciate culture and who manage to establish team relationships with others. These types of people pursue continuous change. Therefore, openness to experience can be a good indicator of creativity since these individuals enjoy hybridizing knowledge. At the other extreme we find people with a more conventional thinking (as Brandy) and probably more resistant to change since they prefer what is known and familiar.

Sum of or recollect the different features of democracy ? ​

Answers

The different characteristics of democracy are related to the types of democracy that currently exist.

These types and their characteristics are:

Direct democracy: This democracy allows all citizens of a region to participate directly in the establishment of policies. This type of democracy was exercised in Athens and allowed any citizen (women and slaves not to be considered) to be able to present a bill, in addition to voting on the bills presented. Not only that, citizens could also participate directly in the region's legislative and executive power.

Representative democracy: It is the type of democracy used in republican and parliamentary countries. it is the most common type today and allows citizens to participate in the formation of policies indirectly, through the choice of their representatives, through the election of those who form the legislative and executive power.

Participatory democracy: It can be considered a semi-direct democracy. This is because it allows citizens to vote for their representatives, but it also allows citizens to participate directly in their country's governmental decisions.

Which statement is true regarding asthma?
A) There is decreased responsiveness to environmental stimuli.
B) It is characterized by airway inflammation.
C) It involves irreversible airway obstruction.
D) Extrinsic asthma has adult onset.

Answers

Answer:

The correct answer is B.

Explanation:

Asthma is a chronic inflammation of the airway, it consists of inflammation of the bronchi, which are responsible for bringing air to the lungs, producing an obstruction of these, which deals with recurring episodes of bronchial hyperresponsiveness and a variable obstruction to air flow. All these inflammatory changes can happen abruptly (Acute Asthma) or slowly and continuously (Chronic Asthma). When they appear abruptly it is called "crisis" or acute asthmatic attack. Both the acute and chronic forms can be highly variable in terms of intensity or duration; sometimes they yield alone or with special treatments.

The correct option is A) There is decreased responsiveness to environmental stimuli. Asthma is a chronic inflammatory disorder of the airways that affects people of all ages.

It is characterized by airway hyperresponsiveness, which means that the airways are more easily irritated and constricted than normal.

This can lead to symptoms such as wheezing, shortness of breath, chest tightness, and coughing.

The exact cause of asthma is unknown, but it is thought to be due to a combination of genetic and environmental factors. Environmental triggers that can worsen asthma symptoms include allergens, irritants, and cold air.

Option B is also true, but it is not the only true statement.

Option C is false because airway obstruction in asthma is reversible.

Option D is false because extrinsic asthma can occur at any age, but it is more common in children.

So the correct answer is A. Asthma is a chronic inflammatory disorder of the airways that affects people of all ages.

It is characterized by airway hyperresponsiveness, which means that the airways are more easily irritated and constricted than normal.

Joann is attracted to both men and women, and identifies as a woman. She has been sexually intimate with both genders, and belongs to an LGBT support group as well as an all-heterosexual female sorority. Her significant other is the captain of the football team. According to the American Psychological Associations definition of sexual orientation (APA, 2014), these variations in Joann’s lifestyle are ______________.

Answers

Answer:

Normal.

Explanation:

The American Psychological Association defines sexual orientation as "an enduring pattern of emotional, romantic, and/or sexual attractions to men, women, or both sexes. Sexual orientation also refers to a person’s sense of identity-based on those attractions, related behaviors, and membership in a community of others who share those attractions".

This definition refers to how a person may associate himself/ herself to a particular sexual identity and be attracted to any gender and the behavior that comes from these affections.

A report that many apples contain a cancer-causing preservative called Alar apparently had little effect on consumers. Few consumers planned to change their apple-buying habits as a result of the report. Nonetheless, sales of apples in grocery stores fell sharply in March, a month after the report was issued.
Which of the following, if true, best explains the reason for the apparent discrepancy described above?
(A) In March, many grocers removed apples from their shelves in order to demonstrate concern about their customers' health.
(B) Because of a growing number of food-safety warnings, consumers in March were indifferent to such warnings.
(C) The report was delivered on television and also appeared in newspapers.
(D) The report did not mention that any other fruit contains Alar, although the preservative is used on other fruit.
(E) Public health officials did not believe that apples posed a health threat because only minute traces of Alar were present in affected apples.

Answers

Answer:

(A) In March, many grocers removed apples from their shelves in order to demonstrate concern about their customers' health.

Explanation:

Option A is the right answer, this is because, option A tells us the reason why the sales of apples fell in the following month.

In other words, since majority of the consumers are indifferent to the report, then, considering the listed options, it can only be the unavailability of the apples that caused the sharp reduction in sales.

Hence, the correct answer is "In March, many grocers removed apples from their shelves in order to demonstrate concern about their customers' health."

Answer:

Masculinity

Explanation:

masculinity describes behaviours and attributes or roles associated with the male gender/men and boys. Masculinity can be said to have both social and biological aspects in that they are socially and biologically influenced. One could debate that masculinity is more biologically influenced than it is socially and mostly just manifests socially while others may debate somewhat otherwise. For example men are usually associated with construction jobs. This is because men are known to be stronger physically than women and this is termed biological. However women can also do this kind of job and so it could then be seen as societal influence in trying to allocate roles to men and women.
