Why do you think some ectopic pregnancy locations are more common than others?
Answers
Answer:
The fallopian tube is the most likely place for implantation, because this is the natural path of travel for the sperm. Ectopic pregnancies in different regions of the fallopian tube suggest that the egg gets implanted immediately after fertilization. Abdominal pregnancy is especially unusual, because this is not a normal path for the fertilized egg to take. The cervical pregnancy looks like the fertilized egg transplanted much farther down than normal.

How can you stop yourself from starving yourself when depressed?
Answers
Answer: Honest Awnser
I'm going to be briefly honest with you. I'm not sure if this is a real question or one simply because you're feeling this way. If you're wanting to starve yourself due to depression/feeling bigger. I would simply first talk with someone such as an adult or a doctor to seek help and guidance if you're in need of it. There is no way of just stopping yourself if it is a severe wanting to do something such as starve yourself. But, if it isn't severe I'd slowly move yourself to eat, starting with small snacks to small meals slowly. Don't overdo it by making yourself each a huge meal, but slowly add up to a normal meal.

What is the function of a vascular spasm?
A) it plugs the wound area prior to the adherence of platelets.
B) it constricts the wound area prior to fibrin formation
C) it plugs the wound area after the adherence of platelets
D) it constricts the wound area after fibrin formation
Answers
Answer:
B. It constricts the wound area prior to fibrin formation.
Explanation:
Before the formation of fibrin, vascular spasm constricts the wound area.
Vascular spasmIt is the narrowing of the arteries resulting due to persistent contraction of the blood vessels, also called vasoconstriction.
This can diminish the flow of blood, this can influence any part of the body.
Vascular spasm or vasoconstriction is one of the steps of hemostasis.
It is a brief reflexive contraction at the time of hemostasis, which makes a decrease in the flow of blood to the region.
This takes place just prior to the formation of platelet plug by fibrin.
The formation of platelet plug takes place directly after the rupturing of blood vessel takes place.
After some minutes, the formation of platelet plug takes place completely by fibrin.
Thus, the correct answer is option B.

A) movement; villi, blood vessels, lymphatic vessels
B) movement; muscles and connective tissue
C) absorption; villi, blood vessels, lymphatic vessels
D) absorption; muscle and connective tissue
Answers
Answer:
C) absorption; villi, blood vessels, lymphatic vessels
Explanation:
The villi are many small folds in the intestine (0.5 to 1.6 mm in length) that increase the surface area and thus maximize the absorption of foods. The villi transport nutrients from food to the capillaries and lymphatic vessels which are found close to its surface. The blood vessels support the tissues of the small intestine and they required to transport the nutrients to the body. Moreover, the lymphatic vessels are involved in nutrient absorption by returning the interstitial fluid to the bloodstream.
Mr. Pochettino created a secret ingredient for a breath mint that he thinks will “cure” the bad breath people get from eating fish tacos at the Taco Tent. He asked 100 customers with a history of bad breath to try his new breath mint. He had fifty customers (Group A) eat a breath mint after they finished eating a fish taco. The other fifty (Group B) also received a breath mint after they finished the taco, however, it was just a regular breath mint and did not have the secret ingredient. Both groups were told that they were getting the breath mint that would cure their bad breath. Two hours after eating the fish tacos, thirty customers in Group A and ten customers in Group B reported having better breath than they normally had after eating fish tacos. What did Mr. Pochettino measure in his experiment? Identify the independent variable, dependent variable, and what Mr. Pochettino's conclusion should be.
Answers
Answer:
Explanation:
The group that is recieving the 'intervention' is the experimental group. & The group of people that are not receiving the intervention,they are only for comparison purpose with the experimental group is the control group.
The outcome of the experiment is the dependent variable.
The rest of the variables are independent variables.
1)The people that are not receiving the new breath mint ,are the control group. Group B is the control group.
2)All the customer (both Group A & B ) had bad breath at the start of study i.e., before intervention.
So, Bad breath is an independent variable.
Secondly, all the person are eating krabby patties.
So, ingestion of krabby patties is also an independent variable.
3)The outcome of the study is dependent variable.
So bad breath get cured/or not is the dependent variable.
4)Group A is receiving the new breath mint.So Group A is the experimental group.
Answer:
The independent variable is are all of the variables left after the dependent variable is recognized. The dependent variable is the result of the expierement. Independent variables: Stinky breath and ingestion of the tacos. Dependent variables: The outcome of the expierement. The outcome is basically rather or not the stinky breath was cured or not. Mr. Pochettino's conclusion should be that the secret ingredient, does indeed, definately have a positive effect on curing stinky breath.
Explanation:
The group of people that are collecting the 'intervention' is known as the experimental group of people. The group that is not collecting the 'intervention', well, they are simply just for comparison purposes along side the experimental group. The experimental group of people is also known as the group that is in charge. The dependent variable is whatever the outcome of the experiment is and the independent variables are all of the variables that are left. Group B is the group that is in charge. They are the people that will not receive the new breath mint. Both, group A and group B, had stinky breaths at the start of this study. This means before intervention. First, with that being said, bad breath is then known as an independent variable. Second, all of the people are eating fish tacos. That then makes ingestion of the tacos an independent variable as well. With all of this now recognized, the outcome of the study is known as the dependent variable. Basically, the dependent variable is if the stinky breath is cured or not cured. Finally, group A is receiving the new breath mint making them now the experimental group.

John is a 15 year old young man who is struggling in school, smoking pot, and rebelling pretty strongly against his parents. He tells the therapist that his parents are "devils from hell" and he hates them. He also seems to be depressed and not wanting to do much of anything but smoke. Give 3 possible diagnoses for John and explain why you selected each one.
Answers
Answer: Despite his hatred towards his parents, I would definitely suggest to John that it would be probably a good idea to take some time out of your day and talk to his parents, let them know how he truly feels. Why? Because if he does, maybe his parents will realize the bad things they have done to make John feel the way he feels, and change the way they act.
Another suggestion that I would provide John would be to stay calm, and avoid anything negative. Why? If he does this, over-time, his depression would get better, instead of the negative things in his life making it worse.
Lastly, another suggestion I would provide John includes medical attention. Depression can’t be cured just with avoiding problems. You need to take medicine as well. So, what I would suggest is for John to go see a doctor who is familiar with depression, anxiety, and all that Jazz, so that the doctor can provide John a few medicines he should take daily.
Despite the fact that John despises his parents, I would urge him to talk to them and let them know how he really feels.
What is depression?Depression is defined as a widespread and significant medical condition that has an adverse impact on how you feel, think, and behave. Major depression is challenging since it has numerous underlying causes. The way your brain controls your moods can be impacted by elements like genetic susceptibility, extreme life stressors, substances you may use, and medical disorders.
John would also get medical care from me. Avoiding difficulties alone won't help someone with depression. You must also take your medication. Therefore, I advise John to visit a doctor who is experienced in treating depression, anxiety, and other related conditions so that the doctor can prescribe a few medications for John to take every day.
Thus, despite the fact that John despises his parents, I would urge him to talk to them and let them know how he really feels.
