Answer 1

Atomic size increases down a group and descreases across a period because when going down a group number of shells of elements increases and across periods number of shells stay the same but the number of electrons increases which will cause too much weight on the atom and it gets diminished. so according to that:

3. A

4. B

5.C( because noble gases are stable)

1.A

2.C

Answer 2

Answer:

3. (a)

4. (c)

5. (c)

1. (a)

2. (b)

Explanation:

3.

from left to right across a period the atomic size decreases because the nuclear charge increases while the no. of valence shells remains constant. The strong electrostatic force between the nucleus and the electrons draws the outermost shell inwards resulting in decrease of atomic radius from left to right.

so, the answer is a. atomic radius of elements decreases from left to right.

4.

Argon has the largest atomic size. Yeah I know, I just said that the atomic radius decreases on moving across a period BUT Nobel gases are exception. In fact they have the largest atomic size in a period. This is because their valence shells are complete and this cause the internal electrons to repel each other thus pushing the valence shell away from the nucleus causing the atomic size to increase.

so the answer is c. Argon

5.

Halogens have the smallest radius in a period. Because their nuclear charge is greatest in a period.

so the answer is c. Halogens

CONCLUSION :-

1.

since, the atomic size increases down the group and decreases along a period the biggest elements are arranged in the bottom and in the left side of the periodic table.

so option a.

2. For metals the atomic radius is directly proportional to their reactivity

metals have to lose electrons in order to become stable and the easier they lose electrons the higher is their reactivity also that a metal will lose electrons easily if it's atomic radius is large so that the outermost electrons are loosely bonded and can be withdrawn easily.

so option. b.

A 55-year-old male is sent to your office to have an esophagogastroduodenoscopy. He is a heavy drinker and smoker who also consumes spicy foods on a daily basis. He is quite anxious about having the procedure performed and is afraid he might choke during insertion of the scope. His father and younger brother were both diagnosed with esophageal cancer. His father died, but the brother was just recently diagnosed and is taking chemotherapy.
A. List the risk factors the patient has for developing esophageal cancer.
B. How might you calm the patient's fears about the procedure?

Answers

Answer and Explanation:

A. The risk factors for this patient are age, family history, and smoking and alcoholism. That's because, most cases of esophageal cancer are detected at age 55 years. We must not forget that cancer is a disease with great genetic potential, which means that, as the father and brother of this patient had this type of cancer, this patient has a high probability of developing the same cancer. Furthermore, the constant consumption of cigarettes doubles the risk of developing esophageal cancer. This risk is also increased by alcoholism.

B. To calm the patient down, I would say that there is a very small and almost non-existent risk that he will choke or even feel the endoscopy insertion, as the entire procedure is done with the patient anesthetized and sedated.

The risk factors the patient has for developing esophageal cancer as well as how you can calm the patients fears about the procedure are as follows

A) Risk factors include

People between the age of 45 and 70 have the more risk of esophageal cancer.

If the patient has genetic signs of cancer from the past generations may have highest risk of esophageal cancer.

Males have more risk than women that is 3 to 4 times to develop esophageal cancer.

Alcohol consumption also increases the risk of esophageal cancer.

Too much weight or obesity increases the risk of esophageal cancer.

Deficiency in nutrients, vitamins and minerals can increase risk of esophageal cancer.

B) Calming the patients fears

Make the patient be happy and stress free.

Do exercise which produces mood boost endorphins that get rid of worries and stress.

Stay positive, being friendly keep good health.

Random distribution is also known as predictable spacing.

true ot false?

Answers

Random distribution is not the same predictable spacing. Hence, the correct answer would be False

In actual fact, random distribution can be said to be the direct opposite of predictable spacing.

For example, when a group of numbers is randomly distributed, each number has an equal chance of being located within the distribution. In predictable spacing, each number would have a predefined probability or an unequal chance of being located.

Hereditary fructose intolerance is a genetic condition caused by a variant in the ALDOB gene, which is critical for fructose metabolism. Infants with this condition do not initially display symptoms, but as they are transitioned from breast milk or formula to solid foods, in particular fruit-based foods, they begin to display symptoms, which include vomiting, diarrhea, and low blood sugar. Individuals who do not consume fructose do not display these symptoms. Which of the following describes this condition?

a. It is incompletely penetrant, due to environmental factors.
b. It has variable expressivity, due to environmental factors.incorrect
c. It is incompletely penetrant, due to genetic factors.
d. It has variable expressivity, due to genetic factors.

Answers

It has variable expressivity due to the environmental factors.

The variation in expressivity occurs due to the environmental factors of that individual. Expressivity describes the differences observed in the phenotype between two individuals that belongs to same genotype.

In the condition, when the patient is allowed to consume the fructose based food, so it expresses the change in its body due to no tolerance against fructose so we can conclude that the change occurs due to environment not due to genetics.
