The reason that men who have enlargement of the prostate gland experience urinary symptoms is:_______.A. The prostate gland is part of the urinary system.B. The prostate gland presses on the urethra.C. The prostate gland blocks the bladder.D. The prostate gland surrounds the bladder neck and the urethra.
Answer:
B. The prostate gland presses on the urethra
Explanation:
Benign prostatic hyperplasia (BPH) is caused by the proliferation of prostatic cells, which leads to the inflammation of this gland, squeezing the urethra (i.e., the tube where urine passes) and ultimately reducing the flow of urine. BPH is a chronic condition progressive with age, thereby it is associated with old men. Although in principle BPH isn't dangerous, high pressure on the urethra may lead to incomplete emptying bladder and infections in the urinary tract.

How is weight affected by the location?
The gravitational pull varies slightly as one moves across the Earth’s surface, depending on latitude and topology, since the Earth isn’t a perfectly round ball.
The further away from the Earth an object is, the lighter it is. At the southern pole of the Earth, an object's mass is slightly greater than its mass at the equator because the Earth's polar radius is slightly smaller than its equatorial radius.
Body weight changes with altitude. Body weight changes as acceleration due to gravity changes. Weight decreases with altitude. The weight of an object changes with altitude.

Convert the following measurements to scientific notation format:
4.2 milliliters= ______?_______ x 10? liters
Scientific notations are used to write the numerical values in easier formats. The unit conversion of the volume can be written as 4.2 milliliters = 4.2 × 10³ liters.
What is scientific notation?Scientific notation has been the way to write the smaller and larger numbers in the form of coefficients and a base raised by the exponential powers. It uses decimal and base 10 to write the numerical values.
It is generally used to write the converted units that are larger or smaller. The exponential power to the base in scientific notation is non-zero integers and can be either positive or negative.
The units of volume can be converted from mL to liter as:
1 mL = 1000 liters
Given,
Volume = 4.2 milliliters
Converting units as:
1 mL = 1000 liters
4.2 mL = 4200 liters
It can be written in scientific notation format as: 4.2 × 10³ liters.
Therefore, the scientific notation is written as, 4.2 × 10³ liters.

Discuss the role of proteins in membrane structure and transport of molecules across the membrane?
The role of proteins in membrane structure and transport of molecules
across the membrane include the production of hydrophilic pores to aid
movement of molecules into the cell.
Proteins are organic substances found in cells which produce pores which
have a high affinity to water thereby allowing other important molecules
enter into the cell.
It is a very important feature of the cell membrane as it ensures there are
enough nutrient needed by the cell to prevent starvation and death.

Your doctor prescribed eye drops for you to treat a certain condition. You obtain the eye drop liquid medication in a small bottle containing a total volume 20 ml. Your instructions were to apply 2 drops in each eye at night. Given that the volume of 1 drop is 0.05 ml. Calculate many days will the eye drop liquid medication last?
Answer:
100 days
Explanation:
1 drop is .05 mL
2 drops are 0.1 mL BUT there are TWO EYES so 0.1mL x 2 = 0.2mL
the math would be 20mL x 1day/0.2mL = 100.
Your doctor prescribed eye drops for you to treat a certain condition. There will be 100 days that the eye drops liquid medication last.
What is liquid medication?Patients who have trouble swallowing tablets and capsules, such as children and the elderly, are more likely to utilize liquid medications. The several kinds of liquid medications include syrups, suspensions, and solutions.
The bottle has 20 ml of liquid
the dose is 2 drops per eye per day
one drop equals 0.05 ml
the average human being has 2 eyes (inferred)
Now let's see how much medicine we use in one day:
2 drops per eye per day
Substitute numbers for words:
2 x 0.05 x 2 = 0.2 ml used per day
How long will the bottle last?
20 ml ÷ 0.2 ml per day = 100 days
Therefore, the days will the eye drop liquid medication last are 100 days.

Do you think, what is currently being done in your community,
adequately promotes social and environmental justice?
Answer:
a little bit
Explanation:
there are people who do the right thing and they are people who do they wrong things
No I do not think what is currently being done in your community, adequately promotes social and environmental justice.
Social justice refers to when resources are distributed in society in such a way that everyone gets a fair share.
Environmental justice is when everyone in society gets a fair treatment regardless of their demographic characteristics such as race, nationality or even gender.
From a global community perspective, I do not think social and environmental justice are being adequately promoted because:
resources are not being fairly distributed which is why we have poor countries and rich countries as well as billionaires while in some areas some people barely made a dollar a day. people are also being discriminated against everyday based on their races, color, gender and nationality and it does not seem to be ending.In conclusion, more work needs to be done to ensure social justice in the global community.

Fats composed of fatty acids that have double bonds in the fatty acids and have fewer than the maximum number of hydrogen atoms are:_______.
Answer:
The options are
A. Saturated
B. Liquids at room temperature
C. Solid at room temperature
D. Generally found in animal fats
E. Made of glycerol plus two fatty acids
The answer is B. Liquids at room temperature
Explanation:
Fats composed of fatty acids that have double bonds in the fatty acids and have fewer than the maximum number of hydrogen atoms are liquids at room temperature.
This is because the deficiency in the maximum number of hydrogen atoms makes reduced the high bond strength synonymous with solids. This is why the lipids are known to be liquids at room temperature.
Ester of the fatty acids are called fats and are a part of the diet. The hydrogen atom in the fats when less than the maximum is liquid at room temperature.
What are fatty acids?Fatty acids are the component of fats that can be saturated and unsaturated depending tin the bond and the number of hydrogen atoms. They provide energy to the muscle and the organs of the body.
The fats that contain a single bond and a maximum number of hydrogen atoms bonded are called saturated fats, they are solid at room temperature.
The fats that contain double bonds and fewer hydrogen atoms bonded in the fats are called unsaturated fatty acids, they are liquid at room temperature.
Therefore, unsaturated fats are liquid at room temperature.

Threonine is a standard amino acid with a polar side chain.Identify the chiral centers in threonine. a. the carboxyl carbon b. the amino nitrogen c. carbon b d. carbon c e. carbon a
Answer:
Threonine has two chiral centers.
The correct options are c. carbon b and d. carbon c
Explanation:
Chiral centers are those that have four different groups of atoms bonded to it. Carbon a has three atoms of hydrogen attached to it so it can't be a chiral carbon. It isn't the carboxyl carbon either since it is double bonded to oxygen. And the amino nitrogen does not qualify anyway because it is bonded to three different groups of atoms, not four.
